If you have questions about any comments, you may contact the individual commenter or direct your questions through the Project Planner, Ted Shepard, at 970-221-6343 or tshepard@fcgov.com. Comment Summary: Department: Planning Services Contact: Ted Shepard, 970-221-6343, tshepard@fcgov.com Topic: General Comment Number: 1 Comment Originated: 09/10/2018 The proposed development project is subject to a Type 2 (Planning and Zoning Board) review and public hearing. The applicant for this development request is required to hold a neighborhood information meeting prior to formal submittal of the proposal. Neighborhood meetings offer an informal way to get feedback from your surrounding neighbors and discover any potential hiccups prior to the formal hearing. Please contact me, at 221 6343, to assist you in setting a date, time, and location. I and possibly other City staff would be present to facilitate the meeting. HCM response: Neighborhood Meeting was held on Wednesday September 26, 2018 Comment Number: 2 Comment Originated: 09/10/2018 Please provide landscape plans and details with planting list and legend. Overall planting plan to show full tree stocking, building foundation planting and parking lot screening and interior lot planting islands. HCM response: See attached landscape plan submitted with SPAR package 2 Comment Number: 3 Comment Originated: 09/10/2018 Off-street parking requirements for proposed 55,333 SF building. The parking requirements for general office use is minimum 1/1000 SF and 3/1000 SF of gross leasable space of proposed building. For medical office use it is min. 2/1000 SF and 4.5/1000 SF max. HCM response: Using the assumption of one (1) space per 1,000 SF, the campus current has 261,863 GSF not including storage facilities, which equates to 262 parking spaces (or 269 spaces if you include storage facilities), and per the parking count matrix below there are currently 2,072 spaces available. If we include the approximate 61,000 GSF for the new Healthcare Careers Center we will have a new grand total of 322,863 GSF which will increase the required parking number to 330 spaces (including storage facilities), which will still be well below required capacity. For Handicap parking, there are 41 spaces and per the zoning requirement 29 handicap parking spaces are required.

Referenced drainage reports are the Master Drainage Study - Front Range Community College Campus, dated May 22, 2014 and the Master Drainage Study – Front Range Community College Campus, dated December 1, 2010. JVA Response: The site will conform to the Campus Drainage Master Plan, which is included with this Submittal for reference. Comment Number: 3 Comment Originated: 09/10/2018 09/10/2018: DOCUMENTATION REQUIREMENTS (SITE SPECIFIC COMMENT): A drainage report (or addendum to the previous master drainage study) and construction plans are required, and they must be prepared by a Professional Engineer registered in the State of Colorado. The drainage report must address the four-step process for selecting structural BMPs as well as show how the added building is within the impervious assumptions, runoff values and volume provided in the existing detention pond and conveyance systems. JVA Response: See attached drainage memo Comment Number: 4 Comment Originated: 09/10/2018 09/10/2018: IMPERVIOUSNESS DOCUMENTATION (STANDARD COMMENT): It is important to document the existing impervious area since drainage requirements and fees are based on new impervious area. An exhibit showing the existing and proposed impervious areas with a table summarizing the areas is required prior to the time fees are calculated for each building permit. JVA Response: The increase in impervious area has been provided on attached site plan SP-1. 4 Comment Number: 5 Comment Originated: 09/10/2018 09/10/2018: STANDARD WATER QUALITY REQUIREMENTS (STANDARD COMMENT) Standard water quality is provided in the existing extended detention basin located at the northeast corner of the campus. The water quality capture volume must be shown to be adequate with the addition of this project, or additional water quality capture volume will need to be added somewhere on the campus. The general requirement for water quality is that fifty percent of the site runoff is required to be treated using the standard water quality treatment as described in the Fort Collins Stormwater Manual, Volume 3-Best Management Practices (BMPs). (http://www.fcgov.com/utilities/business/builders-and-developers/development-f orms-guidelines-regulations/stormwater-criteria) Extended detention is the usual method selected for water quality treatment; however, the use of any of the BMPs is encouraged. JVA Response: Storm water quality is already included in the downstream regional detention pond. Comment Number: 6 Comment Originated: 09/10/2018 09/10/2018: LID REQUIREMENTS (STANDARD COMMENT): (??) Low Impact Development (LID) requirements are required on all new or redeveloping property which includes sites required to be brought into compliance with the Land Use Code. These require a higher degree of water quality treatment with one of the two following options: 1. 50% of the newly added or modified impervious area must be treated by LID techniques and 25% of new paved areas must be pervious. 2. 75% of all newly added or modified impervious area must be treated by LID techniques. JVA Response: The HCCC design will incorporate LID techniques Comment Number: 7 Comment Originated: 09/10/2018 09/10/2018: INSPECTION AND MAINTENANCE (STANDARD COMMENT): There will be a final site inspection of the stormwater facilities when the project is complete and the maintenance is handed over to an HOA or another maintenance organization. Standard operating procedures (SOPs) for on-going maintenance of all onsite drainage facilities will be included as part of the Development Agreement. More information and links can be found at: http://www.fcgov.com/utilities/what-we-do/stormwater/stormwater-quality/low-im pact-development FRCC: The College performs all necessary maintenance on the on-site campus drainage features. 5 Comment Number: 8 Comment Originated: 09/10/2018 09/10/2018: FEES (STANDARD COMMENT): Stormwater Development Fees include two components: Plant Investment Fees (PIFs) and Review Fees. 1. PIFs (2018) are $8,217/acre of new impervious area over 350 square feet ($8,217 x % imperviousness x site acreage) 2. Review Fees are $1,045/acre of new impervious area and based on the impervious area rate factor (i.e. $1,045 x rate factor (based on % imperviousness) x site acreage) Fees are to be paid at the time of the issuance of the first building permit. There are no fees charged for existing impervious areas. Stormwater Development Fees for parking lots or other projects that do not require a building permit are due prior to project approval. The fees are calculated the same as for project sites with buildings. More information on stormwater fees can be found at: http://www.fcgov.com/utilities/business/builders-and-developers/plant-investmen t-development-fees or contact our Utility Fee and Rate Specialists at (970) 416-4252 for questions on fees. FRCC Response: will continue to coordinate with the city for required fees Contact: Jesse Schlam, 970-218-2932, jschlam@fcgov.com Topic: Erosion Control Comment Number: 1 Comment Originated: 08/30/2018 08/30/2018: The site disturbs more than 10,000 sq. ft. and if it were constructed within the City's MS4 Boundaries then Erosion and Sediment Control Materials would need to be submitted. The erosion control requirements can be located in the Stormwater Design Criteria under the Amendments of Volume 3 Chapter 7 Section 1.3.3. a copy of the erosion control requirements can be found at www.fcgov.com/erosion. The Erosion Control Materials would normally be submitted at time of the first round of FDP. Based upon the area of disturbance, State permits for stormwater will be required since the site is over an acre and should be pulled before Construction Activities begin. Please consult with FRCC's Permit Compliance folks to discuss meeting the FRCC's MS4 Permit requirements. If you need clarification concerning the Erosion Control Material Requirements or Comments presented above please contact myself. Jesse Schlam (970) 224-6015 jschlam@fcgov.com Haselden Response: The campus will coordinate with the City throughout construction and provide a plan for addressing erosion control. 6 Department: Water-Wastewater Engineering Contact: Heather McDowell, 970-224-6065, hmcdowell@fcgov.com Topic: General Comment Number: 1 Comment Originated: 09/10/2018 09/10/2018: OTHER SERVICE DISTRICT (SITE SPECIFIC COMMENT): This project site is located within the Fort Collins Loveland Water District and the South Fort Collins Sanitation District for water and sewer service. Please contact them at (970) 226-3104 for development requirements. HCM Response: Noted Department: Traffic Operation Contact: Tim Tuttle, 970-221-6820, TTUTTLE@fcgov.com Topic: General Comment Number: 1 Comment Originated: 09/10/2018 09/10/2018: Based on the ITE Trip Generation Manual the estimated number of trips generated for the new building would warrant a Traffic Impact Study. The TIS will help the City analyze the operations of the intersections and make adjustments if needed. Please contact me to scope the study at 970-221-6820. HCM response: FRCC contracted with Delich Associates to provide a Traffic Impact Study per the attached Document dated October 26, 2018. Comment Number: 2 Comment Originated: 09/10/2018 09/10/2018: Will the temporary construction access be returned to its existing condition following construction. Haselden response: Yes, the proposed temporary construction access point at the abandoned bus stop on Shields Street will be returned to its original condition after construction is completed. Department: Engineering Development Review Contact: Marc Virata, 970-221-6567, mvirata@fcgov.com Topic: General Comment Number: 1 Comment Originated: 09/11/2018 09/11/2018: The temporary access drive onto Shields would need to be further reviewed in its design and spacing, to ensure it operates as right-in, right-out and that its access spacing is not detrimental to the overall traffic in the area. Haselden response: the construction team will coordinate with the city for final approval for the layout of the temporary construction access drive at the existing abandoned bus stop on Shields Street. This temporary curb cut is critical to avoid conflicts with truck traffic and the adjacent Harmony Library. Comment Number: 2 Comment Originated: 09/11/2018 09/11/2018: The construction of the project should be staging in a manner that allows two feet of separation/buffer from the back of sidewalk along Harmony and Shields. Haselden Response: Understood. This will be accommodated on site 7 Comment Number: 3 Comment Originated: 09/11/2018 09/11/2018: There was a parking lot project built on the south end of the campus with a replat that was part of an earlier submittal. It does not appear that this project was ever completed with the City between plans and the plat. FRCC Response: This parking lot project has been completed. The college purchased a portion of the adjacent land owned by the church. The college will look into the status of the plat. Comment Number: 4 Comment Originated: 09/11/2018 09/11/2018: Street cuts onto Harmony Road or Shields Street, such as for utilities and/or the temporary driveway connection, would require a Development Construction Permit (DCP) and/or an excavation permit/drive approach permit prior to starting any work. FRCC Response: will continue to coordinate with the city for required fees and permits Comment Number: 5 Comment Originated: 09/11/2018 09/11/2018: If going through City of Fort Collins for building permitting, Larimer County Road Impact Fees and Transportation Expansion Fees are due at the time of building permit. Please contact Kyle Lambrecht at 221-6566 if you have any questions. FRCC response: Since this is a State project, the building permit will be provided by a third-party code review firm contracted with the State of Colorado (Safe Built). Comment Number: 6 Comment Originated: 09/11/2018 09/11/2018: The remaining comments are standard comments for reference. Comment Number: 7 Comment Originated: 09/11/2018 09/11/2018: The City's Transportation Development Review Fee (TDRF) is due at the time of submittal for any appropriate City review.

Front Range Community College Health Care Careers Center – Project Narrative Site Plan Advisory Review Submittal November 27, 2018 This document summarizes the design goals for the new Health Care Careers Center (HCCC) for Front Range Community College (FRCC). FRCC hired the Haselden Construction | Hord Coplan Macht Design/Build (D/B) team in August 2018 to verify the HCCC program requirements and to start the design for the project. The HCCC building will consolidate the Larimer Campus Nursing and Allied Health departments into one health sciences focused building. The project will not alter any existing zoning or Land Use Codes. The following are a few of the design priorities identified by the FRCC President as goals for the team: • High stakeholder involvement (both internal and external) • Exterior view of the building at the street intersection creates a prominent welcome to the campus. • Design that is generally compatible with the rest of the campus (but not necessarily mimicry) The D/B team has kept these goals in mind throughout the past several months for the schematic design phase. SPAR timeline: • FRCC and the design/build team met with the city on September 12, 2018 to discuss the goals for the project and the process for the SPAR review. • The D/B team then submitted a drawing package for a Preliminary Design Review on September 29, 2018. • FRCC met with the city forester on September 19, 2018 to review existing site trees and identify trees that should be protected during the project construction. The city forester provided documents that outline guidelines for landscaping that we have incorporated into our landscape plan. • FRCC held the required neighborhood meeting on September 26, 2018. There was not any indicated opposition to the project during the meeting, and several neighbors expressed an interest in continuing the campus connection to the neighborhood to the south with the pedestrian pathway. To meet the project schedule identified by FRCC to complete construction by June 2020, Haselden has determined that they will need to start construction in April 2019. Therefore, the D/B team created a design schedule that includes an early bid package for earthwork, site utilities, structural foundations and steel procurement that will be submitted in February, and a second bid package for the remainder of the project scope of work due in April 2019. The D/B team worked closely with the User Groups, the project Steering Committee and the Executive Committee to verify program needs and to assure required adjacencies for each program location to develop a floor plan layout. The HCCC is to be a 61,000 GSF, 2-story structure located at the vacant lot at the northwest corner of the Larimer Campus. The HCCC will be located at the southeast corner of the Shields Street and Harmony Road intersection, just north of the campus/community library, and west of the existing Sunlight Peak campus building. The site legal description is Page 2 of 3 as follows: A portion of land located in the northwest quarter of Section 2, Township 6 North, Range 69 west of the 6th P.M., City of Fort Collins, County of Larimer, State of Colorado. The corner location for the HCCC building makes for a highly visible project site that provides an opportunity for the building to create a ‘Gateway’ to campus and provides an opportunity to create a stronger community connection to campus than the rest of the existing campus buildings currently provide. The two existing campus access points from Harmony Road and from Shields Street will remain in their current condition and there will not be any additional access points provided to campus for this development, except for a temporary construction access point at an abandoned bus stop pull out area on Shields Street, just southwest of the building site. Please see the attached Traffic Impact Study completed by Delich Associates regarding anticipated traffic impact on the existing intersections that provide access to campus. The existing parking lots on campus provide 2,072 parking spaces, which is more than 6 times the zoning requirement of 324 spaces; therefore, no additional parking, or parking lot lighting, is planned to be provided for this development. The project goal is to avoid losing any existing parking spaces and to add a drop off/pick up lane along the south edge of the HCCC building. The exterior design for the HCCC balances the contextual use of building materials and scale found on existing campus buildings with a prominent vertical translucent atrium that provides a primary entry to the campus core, and a secondary entry to the street intersection. To relate to campus context the building materials include red and tan brick with layered, horizontal brick banding, and the building mass incorporates a unified base and parapet top elements that reference existing campus building forms. The brick masses are ‘eroded’ at corners to create translucent openings, and a variety of vertical and horizontal shading devices have been incorporated at windows to reduce heat gain and glare issues, and to also provide a rhythm of horizontal and vertical forms. The building will also include FRCC branding/signage visible from the intersection. The atrium has a prominent, angled form that slopes up at each entry, providing glass walls at each entry and at clerestories above the lower roof forms. The primary entry will be from the southeast corner of the atrium and is designed to align with the existing pedestrian walkway from the parking lot. A new prominent plaza provides an intersection for the two main pedestrian pathways on campus and leads students and visitors directly to the main entry. The plaza design incorporates the existing pollinator garden west of Sunlight Peak, as well as outdoor study areas, benches and landscape areas. Since this project is partially State funded there will be an art sculpture element in the plaza area, with the final location determined by a committee. There will be an added handicap accessible connection from the entry plaza to the existing bus drop off on Harmony Road, just north of Sunlight Peak. A new drop-off lane has been added at the north edge of the existing parking lot, which is directly south of the project site. There are no natural wetlands on the proposed building site. A trash enclosure will be located at the southwest corner of the building and will be built into significant site grades that slope up toward Shields street, which will assist with screening the dumpsters. The materials for the enclosure will be brick on block structure, with brick colors/pattern that will complement the building. Gates for the enclosure will be painted steel. The college is participating in the city of Fort Collins IDAP process and held our kick-off meeting on November 15, 2018, with the goal to be a LEED Gold certified building. Page 3 of 3 The existing observatory is currently located on the south edge of the proposed building site and so will be relocated 100 feet to the south during the construction phase. The new location will be half way between the HCCC building and the Harmony Library. Attached are the responses to the city review from the Preliminary Design Review submittal for your record. Please contact us if you have any questions about this SPAR submittal in preparation for our work session with the city team on December 19, 2018 and the Planning and Zoning Board meeting on January 17, 2018.

Shields Street Fort Collins, CO 80526 Re: Larimer Campus - Northwest Detention Pond Status Crestone Project No.: 13020 Dear Mr. DeRemer: Per your request on April 17, 2018, we’ve prepared this letter to identify the status of the existing detention pond located west of the Sunlight Peak (SP) building and north of the Observatory and Harmony Library Parking Lot at the northwest corner of the Larimer Campus. We’ve reviewed the following Master Drainage Studies for the Larimer Campus in the preparation of this letter: 1. Master Drainage Study – Front Range Community College Campus, prepared by Interwest Consulting Group, dated December 1, 2010 revised. (AKA 2010 Master Study) 2. Master Drainage Study – Front Range Community College Campus, prepared by Interwest Consulting Group, dated May 22, 2014. (AKA 2014 Master Study) A summary of the 2010 Master Study as it pertains to the subject detention pond has been provided as follows: 2010 Master Study Summary: The subject detention pond was constructed with the Harmony Library Parking Lot project in 2010/2011 to help mitigate any effects from the parking lot development on the existing storm sewer system. The 2010 Master Study identified the existing storm sewer system which the Harmony Library Park Lot is tributary to (i.e. Storm System 1) as being undersized. The subject detention pond is located within Basin A1 and is required to be installed to attenuate developed flows from the interim condition Basin A1 until improvements to the campus’ storm drainage conveyance and storage systems are constructed. Required storm drainage conveyance improvements include the construction of a new storm pipe (36”) located on the north side of the SP building which will convey the developed flows from Basin A1 east to the existing riprap channel adjacent to Harmony Road which outfalls to the campus’ North Detention Pond located at the northeast corner of the campus. Required storage improvements include increasing the North Detention Pond volume by raising the pond’s spillway elevation and providing additional pond excavation to account for the additional April 23, 2018 Dennis DeRemer; Front Range Community College – Northwest Detention Pond Status Page 2 imperviousness proposed throughout the campus and to provide additional water quality capture volume. Additionally, the 2010 Master Study includes modifying the North Detention Pond outlet structure to accommodate the additional water quality capture volume and detained volumes. Please refer to select excerpts and maps attached to this letter from the 2010 Master Study. In 2011, the storm drainage conveyance and storage systems identified in the 2010 Master Study were constructed. This includes the 36” storm pipe conveyance for Basin A1 as well as the North Detention Pond storage improvements and outlet structure modifications. A summary of the 2014 Master Study as it pertains to the subject detention pond has been provided as follows: 2014 Master Study Summary: The 2014 Master Study states, “In the current condition, Basin A1 drains to a temporary pond. This temporary pond drains north to the existing 36” RCP Storm System located to the northeast that conveys the flow east to the Northern Channel adjacent to Harmony Road at the northeast corner of the SP building and finally to the North Detention Pond. This temporary pond can be removed at any time, the existing storm pipes and swales are adequate to receive undetained water now and with future building. This entire basin will drain to the existing 36” RCP Storm System.” Please refer to select excerpts and maps attached to this letter from the 2014 Master Study. Based on the 2014 Master Study, all improvements which were required to be installed for the removal of the subject detention pond have been constructed and the subject detention pond may be removed at any time. Please Note - The 2014 Master Study identifies conveyance and storage capacity allowances provided by the existing storm drainage system for future identified planned improvement areas. The study also identifies triggers for future improvements to the storm drainage conveyance and storage systems, including improvements for North Detention Pond. We recommend that Front Range Community College provide a complete copy of the 2014 Master Study to all perspective designers for their review and use in preparing their respective designs of future improvements throughout the Larimer Campus.

With today’s pond size and the historic 100-year release rate of 42 cfs, 0 cfs would spill over the spillway to the drainage channel adjacent to the Coventry Subdivision. Please refer to Appendix D for the North Detention Pond calculations. The South Detention Pond is located in the southeast portion of the campus adjacent the Clarendon Hills and Coventry Subdivisions. This pond treats water quality and detains flow from the newest parking lot. The pond releases to the Southern channel that directs flow to the North Detention Pond. The South Detention Pond releases 0.6 cfs and is a negligible impact to the overall release from the North Pond. 5. DRAINAGE FACILITY DESIGN 5.1 Specific Flow Routing A summary of the drainage patterns within each basin is provided in the following paragraphs. The Master Drainage Plan Current Condition map is located in the back pocket of this study. Basins A and A1 include the northwest portion of the site. These basins contain portions of HL, BP and RP buildings and all of SP and CP buildings. With current conditions, basins A and A1 consist of 8.0 acres. Basin A is 3.8 acres and flow from this basin enters Storm System 1 and is conveyed east to the North Detention Pond. Basin A1 is 4.2 acres and is the area west of the SP building, consists of a parking lot and has space for an additional impervious area in the future. Once an improvement adding hard surface is completed, it will then be considered completely built out. For the purposes of this report, basin A1 will be considered in its current condition. In the current condition, basin A1 drains to a temporary pond. This temporary pond drains north to the existing 36” RCP Storm System located to the northeast that conveys the flow east to the Northern Channel adjacent to Harmony Road at the northeast corner of the SP building and finally to the 7 North Detention Pond. This temporary pond can be removed at any time, the existing storm pipes and swales are adequate to receive undetained water now and with future building. This entire basin will drain to the existing 36” RCP Storm System. Basin B is 3.2 acres and includes the center portion of the site. This basin includes portions of buildings BP, RP, LP and MA. Flows from this basin enter existing Storm System 2 and are conveyed east to the North Detention Pond. Basin C is 14.3 acres and includes the student parking lots located in the center of the site. Flows in this area will be routed east in existing Storm System 3 to the North Detention Pond. Basin D is a total of 5.5 acres and consists of the south central portion of the site. It consists of parking lots and the existing Southern Channel. This basin drains north via curb cut and inlet in the parking lot to the existing grass lined Southern Channel located between the existing student parking lots. Culverts are sized to pass this flow and the additional offsite flow from the Westbury Pond and Shields under the two drive aisles that access the parking lot. Basin E is 4.2 acres and is located in the east portion of the site. The majority of this basin is a parking lot. Flow from this basin sheets to the northeast and into the existing North Detention Pond. If an addition of a building does occur in the future, it will occur in the existing parking lot and will include removal of pavement and will not affect the overall site imperviousness of this basin. Basin F is 6.7 acres and consists of the northeast portion of the site and includes the Northern Channel and the North Detention Pond. It also contains the MP and FB buildings. Basin G is 5.2 acres and is located in the southwest portion of the campus. This basin includes the southern parking lot and is north of the irrigation ditch and is considered the Southwest Parking Lot Expansion. The basin drains via a self-contained storm system to a detention and water quality pond located in the southeast portion of the campus adjacent the Clarendon Hills and Coventry Subdivisions. The pond detains this basin’s 100-year event to historic 2-year flows and is sized to also handle runoff from a future phase of 8 parking area. The total 100-year developed release rate for the Southwest Parking Lot Expansion is slightly over the 10-year historic runoff. Construction of a parking lot and South Detention Pond in this basin is currently underway (2014). Design of this area is included in JVA Consulting Engineers, “FRCC Larimer Campus—South Parking Lot (Phase I & II) Final Drainage Letter”, dated January 12, 2014 in Appendix E of this document. Because of the detention provided in Basin G, this acreage is not included in the North Detention Pond volume calculations. 5.2 Proposed Improvements The current conditions of the portions of the site draining to the existing North Detention Pond include 41.9 acres at 61% imperviousness. The existing pond, based on a current topographic survey, has 3.1 ac-ft of storage (not including water quality capture volume). The required water quality capture volume is 1.0 ac-ft and is achieved at elevation 5061.8’ based on the as-built shots of the water quality outlet structure. With today’s pond size and the historic 100-year release rate of 42 cfs, the 100-yr water surface elevation is at elevation 5063.8’ and spillway is at elevation 5063.9’. The entire site is detained and 0 cfs spills over the spillway to the drainage channel adjacent to the Coventry Subdivision. Currently, the pond has capacity for 70,000 square feet of additional impervious area allowing for Future Impervious Areas A and B to be completed without needing to upgrade the North Detention Pond or water quality outlet structure. These improvements equate to the 41.9 acres having 65% imperviousness. With these conditions, the required water quality capture volume will be 1.1 ac-ft at elevation 5061.8’. With today’s pond size and the historic 100-year release rate of 42 cfs, the 100-year water surface and spillway elevation will be at elevation 5063.9’. Please refer to Appendix D for pond calculations. Please refer to the Master Drainage Plan Current Conditions map located in the back pocket for two delineated areas where future impervious areas could be located. Area A is located in the northwest corner of the site within Basin A1. Area B is in Basin F and is located in the flat area adjacent to the Mount Antero Building. If changes to the 41.9 acres that drain to the North Detention Pond cause a percent imperviousness to be greater than 65%, the pond must be reanalyzed using EPA SWMM 5.0 software and a new water quality and detention volume must be calculated.

Page 1 of 51 PURPOSE AND SCOPE OF STUDY This report presents the results of a geotechnical evaluation performed by GROUND Engineering Consultants, Inc. (GROUND) for Front Range Community College in support of design of the proposed Health Care Career Center in Lafayette, Colorado. Our study was conducted in general accordance with GROUND’s proposal No. 1809- 1662 with Front Range Community College, dated September 18th, 2018. A field exploration program was conducted to obtain information on the subsurface conditions. Material samples obtained during the subsurface exploration were tested in the laboratory to provide data on the engineering characteristics of the on-site soils. The results of the field exploration and laboratory testing are presented herein. This report has been prepared to summarize the data obtained and to present our findings and conclusions based on the proposed development/improvements and the subsurface conditions encountered. Design parameters and a discussion of engineering considerations related to the proposed improvements are included herein. This report should be understood and utilized in its entirety; specific sections of the text, drawings, graphs, tables, and other information contained within this report are intended to be understood in the context of the entire report. This includes the Closure section of the report which outlines important limitations on the information contained herein. This report was prepared for design purposes of Front Range Community College(FRCC) based on our understanding of the proposed project at the time of preparation of this report. The data, conclusions, opinions, and geotechnical parameters provided herein should not be construed to be sufficient for other purposes, including the use by contractors, or any other parties for any reason not specifically related to the design of the project. Furthermore, the information provided in this report was based on the exploration and testing methods described below. Deviations between what was reported herein and the actual surface and/or subsurface conditions may exist, and in some cases those deviations may be significant. PROPOSED CONSTRUCTION Current plans provided show an approximately 30,000 square foot footprint for the proposed Health Care Career Center along with a supporting paved drive lane and Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 2 of 51 parking spaced on the south side of the proposed facility. The existing observatory is also planned to be relocated to the south of its current position. Additionally, construction will likely include installation of underground utilities. Provided preliminary building loads were 275 kips for maximum column loads and 2 kips per linear foot for wall loads. Provided preliminary grading plans indicate that the anticipated finished floor elevation is approximately 5080.5 feet in elevation. Cuts of up to approximately 9 feet and fills of up to approximately 4 feet will be required to establish anticipated grades. If proposed construction, including the assumed loading conditions, differ from those described above, or changes subsequently, GROUND should be notified to re- evaluate the parameters in this report. SITE CONDITIONS At the time of our exploration, the project site was the northwest corner of the Larimer Campus of Front Range Community College near the intersection of E. Harmony Road and S. Shields Street at Fort Collins. The site supported grass and trees. The site is bordered by the Harmony Library to the south, existing FRCC buildings to the east, West Harmony Road to the north, and South Shields Street to the west. The topography across the site was variable with notable slopes falling from the northwest to the southeast at slopes up to approximately 15 percent. There is an existing drainage ditch and detention on the eastern portion of the site. Fill was observed in several of the test holes likely associated with previous site grading at the project site. The exact extents, limits, and composition of any man-made fill were not determined as part of the scope of work addressed by this study, and should be expected to exist at varying depths and locations across the site. SUBSURFACE EXPLORATION The subsurface exploration for the project was conducted on October 31st, and November 1st, 2018. A total of eleven (11) test holes were drilled at the project site. Nine (9) test holes were drilled within the approximate footprint of the proposed building. One (1) test hole was drilled near the proposed future location of the observatory. One(1) test hole were drilled within the proposed parking lot expansion. The test holes were drilled with a truck-mounted, continuous flight power auger rig to evaluate the subsurface conditions as well as to retrieve soil samples for laboratory testing and Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 3 of 51 analysis. The foundation test holes were drilled to depths of approximately 24 to 39 feet below existing grades and the pavement test hole was drilled to approximately 5 feet below existing grades. A representative of GROUND directed the subsurface exploration, logged the test holes in the field, and prepared the soil samples for transport to our laboratory. Samples of the subsurface materials were retrieved with a 2-inch I.D. California liner sampler. The sampler was driven into the substrata with blows from a 140-pound hammer falling 30 inches. This procedure is similar to the Standard Penetration Test described by ASTM Method D1586. Penetration resistance values, when properly evaluated, indicate the relative density or consistency of soils. Depths at which the samples were obtained and associated penetration resistance values are shown on the test hole logs. The approximate locations of the test holes are shown in Figure 1. Logs of the exploratory test holes are presented in Figures 2 to 4. Explanatory notes and a legend are provided in Figure 5. LABORATORY TESTING Samples retrieved from our test holes were examined and visually classified in the laboratory by the project engineer. Laboratory testing of soil samples obtained from the subject site included standard property tests, such as natural moisture contents, grain size analyses, liquid and plastic limits, and swell-consolidation testing. Water-soluble sulfate and corrosivity testing was completed on selected samples of the soils as well. Laboratory tests were performed in general accordance with applicable ASTM protocols. Results of the laboratory testing program are summarized on Tables 1 and 2. SUBSURFACE CONDITIONS Geologic Setting - Published geologic maps, e.g., Colton (1978),1 depict the project site as underlain by Slocum Alluvium (Qs) consisting of cobble and gravel with reddish brown clay. The surficial deposits at the project site are mapped as being underlain by 1 Colton, R.B., 1978, Geologic map of the Boulder-Fort Collins-Greeley area, Front Range Urban Corridor, Colorado: U.S. Geological Survey, Miscellaneous Investigations Series Map I-855-G, scale 1:100,000 Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 4 of 51 the Pierre Shale (Kp) consisting of silty shale, sandstone, and shale. A portion of that geologic map is reproduced below. The claystones and siltstones can be moderately to highly expanse and the formation includes well cemented beds that can be very hard and difficult to excavate. Local Conditions The subsurface conditions encountered in the test holes generally consisted of a layer of topsoil2 materials approximately 1 foot in thickness. The topsoil was underlain by fill materials that consisted of sandy clay with trace gravels that generally extended to depths ranging from 3 to 6 feet below existing grades. Sand and clay materials were encountered locally below the fill in test holes 2, 3 and 10. Sand and clay with gravel was encountered below the sand and clay and fill materials. Claystone bedrock was encountered below the sand and clay with gravel materials at depths ranging from 8 to 35 feet below existing grades and continued to the test hole termination depths of approximately 24.5 to 39 feet below existing grades. 2 ‘Topsoil’ as used herein is defined geotechnically. The materials so described may or may not be suitable for landscaping or as a growth medium for such plantings as may be proposed for the project. Approximate Project Site Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 5 of 51 It should be noted that coarse gravel, cobbles, boulders, and similarly sized fragments of debris are not well represented in small diameter liner samples collected from 4-inch diameter test holes. Therefore, such materials may be present at varying depths at the project site. Fill materials consisting of sandy clay with trace gravels were fine to coarse grained locally, low to medium plastic, relatively compact, slightly moist to moist, and light brown to dark brown in color. Sand and Clay materials were fine to coarse grained with local gravel, low to medium plastic, stiff/medium dense to hard/dense, moist, and brown to red-brown in color with local caliche deposits. Sand and Gravel with Clay materials were fine to coarse grained with gravel, non to medium plastic, stiff/medium dense to hard/dense, moist to wet, and brown to red-brown to yellow-brown in color with local caliche deposits. Claystone Bedrock was fine grained with siltstone layers, medium to highly plastic, hard to very hard, dry to slightly moist, and brown-gray in color. Swell-Consolidation Testing yielded results ranging from 0.9 percent swell to 0.3 percent consolidation and one swell of 0.2 percent at various surcharge pressures based on estimated overburden pressure. Groundwater was encountered in the test holes at the time of drilling at approximate elevations of 5069 to 5076 feet. When measured 5 days later in test holes 1, 3, 7, and 9 groundwater was at elevations ranging from approximately 5072.5 to 5076 feet. Groundwater levels can be expected to fluctuate, however, in response to annual and longer-term cycles of precipitation, irrigation, surface drainage, nearby rivers and creeks, land use, and the development of transient, perched water conditions. SEISMIC CLASSIFICATION According to the 2015 International Building Code® (Section 1613 Earthquake Loads), “Every structure, and portion thereof, including nonstructural components that are permanently attached to structures and their supports and attachments, shall be designed and constructed to resist the effects of earthquake motions in accordance with Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 6 of 51 ASCE 7, excluding Chapter 14 and Appendix 11A. The seismic design category for a structure is permitted to be determined in accordance with Section 1613 (2015 IBC) or ASCE 7.” Exceptions to this are further noted in Section 1613. Based on extrapolation of available data to depth and our experience in the project area, we consider the site likely to meet the criteria for a Seismic Site Classification of C according to the 2015 IBC classification (Section 1613.3.2). If, however, a quantitative assessment of the site seismic properties is desired, then sampling or shear wave velocity testing to a depth of 100 feet or more should be performed. Utilizing the United States Geological Survey’s Seismic Design Maps Tool (http://geohazards.usgs.gov/designmaps/us/application.php), assuming a Site Class C the project area is indicated to possess an SDS value of 0.149g and an SD1 value of 0.066g for the site latitude and longitude. If however, local codes require quantitative assessment of the site then assuming a Site Class D the tool provides an SDS value of 0.198g and an SD1 value of 0.094g for the site latitude and longitude. FOUNDATION/FLOOR SYSTEM OVERVIEW Geotechnical Considerations for Design: As stated previously cuts of up to 9 feet and fills of up to 4 feet will be required to establish grades for the anticipated finished floor elevation of 5080.5. If simply filled and cut from current elevations the differential fills will likely settle differentially based on depth. Additionally un-documented fills exist locally below the anticipated finished floor elevation. Un-documented fills are generally not geotechnically acceptable as they present an unquantifiable potential for heave and settlement. According to our field and laboratory analysis, it is GROUND’s opinion the materials encountered in our exploration are generally suitable to support the proposed structure on a shallow foundation system consisting of spread footings with a slab-on-grade floor system. However, a uniform fill prism consisting of over-excavated and replaced site materials should be established to mitigate the potentials for differential settlement and the risks associated with undocumented fills. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 7 of 51 Foundation and Floor System: The building footprint should be over-excavated to a common bottom elevation of approximately 5076 feet. This depth of over-excavation will establish a uniform fill prism for floor slabs and spread footing foundations. The fill prism should extend out past the building perimeter by at least 5 feet. The existing site materials should be re-placed in moisture treated and compacted state in accordance with the Project Earthwork section of this report. Greater depths of over-excavation may be required if soft areas are exposed at the time of constructions. A representative of the geotechnical engineer should be retained to verify existing conditions during construction excavation. Due to the proximity of groundwater near the bottom of the over-excavation, localized areas may require stabilization methods such as stabilization rock, aggregate base course materials, and geogrid in some combination to establish a firm platform for filling. Additionally, dewatering operations and the construction of a mud mat may be required to facilitate the construction of any proposed deeper foundations that will bear at or near the groundwater. The Contractor should take care to construct a fill layer of uniform composition to reduce differential post-construction building movements. If materials are imported for, fill with the exception of stabilization rock, they should not be mixed with site materials in the same horizontal fill layer within the building footprint. To use these parameters, the Owner must accept the risk of post-construction foundation movement associated with shallow foundation systems placed on the on-site soils. Utilizing the above parameters as well as other parameters in this report, we estimate likely post-construction foundation and floor movements to be on the order of 1 inch, with 1/2 inch differential movements over spans of about 40 feet. Movement estimates are difficult to predict and actual movements may be more or less The conclusions and parameters provided in this report were based on the data presented herein, our experience in the general project area with similar structures, and our engineering judgment with regard to the applicability of the data and methods of forecasting future performance. A variety of engineering parameters were considered as indicators of potential future soil movements. Our parameters were based on our judgment of “likely movement potentials,” (i.e., the amount of movement likely to be Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 8 of 51 realized if site drainage is generally effective, estimated to a reasonable degree of engineering certainty) as well as our assumptions about the owner’s willingness to accept geotechnical risk. “Maximum possible” movement estimates necessarily will be larger than those presented herein. They also have a significantly lower likelihood of being realized in our opinion, and generally require more expensive measures to address. We encourage the Client, upon receipt of this report, to discuss these risks and the geotechnical alternatives with us. FOUNDATION SYSTEM The design and construction criteria presented below should be observed for a spread footing foundation system. The construction details should be considered when preparing project documents. The precautions and parameters provided below will not prevent movement of the footings if the underlying materials are subjected to alternate wetting and drying cycles. However, the recommended measures will tend to make the movement more uniform, and reduce resultant damage if such movement occurs. Geotechnical Parameters for Shallow Foundation Design: 1) Footings bearing on materials as described in the Foundation / Floor System Overview section above may be designed for an allowable soil bearing pressure (Q) of 2,500 psf. These values may be increased by ⅓ for transient loads such as wind or seismic loading. Compression of the bearing soils for the provided allowable bearing pressure is estimated to be 1 inch, based on an assumption of drained foundation conditions. If foundation soils are subjected to an increase/fluctuation in moisture content, the effective bearing capacity will be reduced and greater post-construction movements than those estimated above may result. 2) To be able to use the allowable bearing capacity values presented above, strip footings should be limited to 6 feet or less in width and pad footing should have a maximum dimension of 10.5 feet. For other estimated settlements associated Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 9 of 51 with allowable bearing pressure values or footing widths exceeding the dimensions above please contact this office. 3) In order to reduce differential settlements between footings or along continuous footings, footing loads should be as uniform as possible. Differentially loaded footings will settle differentially. Similarly, differential fill thickness beneath footings will result in increased differential settlements. 4) Spread footings should have a minimum lateral dimension of 18 or more inches for linear strip footings and 24 or more inches for isolated pad footings. Actual footing dimensions, however, should be determined by the structural engineer. 5) All footings should bear at an elevation 3 or more feet below the lowest adjacent exterior finish grades. 6) Continuous foundation walls should be reinforced top and bottom to span an unsupported length of at least 10 feet. 7) Geotechnical parameters for lateral resistance to foundation loads are provided in the Lateral Earth Pressures section of this report. 8) Connections to the building of all types must be flexible and/or adjustable to accommodate the anticipated, post-construction movements. Shallow Foundation Construction: The following should be considered during the construction of spread footing foundations. 1) Care should be taken when excavating the foundations to avoid disturbing the supporting materials. Hand excavation or careful backhoe soil removal may be required in excavating the last few inches. 2) Footing excavation bottoms may expose loose, organic or otherwise deleterious materials, including debris. Firm materials may become disturbed by the excavation process. All such unsuitable materials should be excavated and replaced with properly compacted fill or the footing deepened. 3) Foundation soils may be disturbed or deform excessively under the wheel loads of heavy construction vehicles as the excavations approach footing bearing Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 10 of 51 levels. Construction equipment should be as light as possible to limit development of this condition. Track-mounted vehicles generally should be used because they exert lower contact pressures. The movement of vehicles over proposed foundation areas should be restricted. 4) All footing areas should be compacted with a vibratory plate compactor prior to placement of reinforcing steel placement for concrete to consolidate loose materials at the surface. 5) Compacted fill placed against the sides of the footings should be compacted in accordance with the criteria in the Project Earthwork section of this report. FLOOR SYSTEM The following measures are recommended to reduce damage, which may result from movement of the slab subgrade material. These measures will not eliminate potential movements. If slab-on-grade construction is used in accordance with the following criteria, as well as other applicable parameters contained in this report, we estimate that potential slab movements may be on the order of 1 inch. The actual magnitude of movement is difficult to estimate and may be more or less. Geotechnical Parameters for Design of Slab-on-Grade Floors 1) Slab subgrade materials shall be over-excavated and replaced in general accordance with the Foundation / Floor System Overview section above. 2) An allowable subgrade vertical modulus (K) of 100 pci may be utilized for lightly loaded slabs supported by over-excavated on-site materials. This value is for a 1- foot x 1-foot plate; they should be adjusted for slab dimension. 3) Based on our experience with reinforced slabs and conversations with the owner, there is a concern with using 4 inch slab thicknesses and reinforcing steel such as #4 bar mats. Slab thicknesses of 5 inches or greater should be considered. Reinforcing clearance and cover can be difficult to achieve during construction of thinner slabs. Lack of proper cover can be detrimental to the finish and appearance of these slabs. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 11 of 51 4) Floor slabs should be separated from all bearing walls and columns with slip joints, which allow unrestrained vertical movement. Slip joints should be observed periodically, particularly during the first several years after construction. Slab movement can cause previously free-slipping joints to bind. Measures should be taken to assure that slab isolation is maintained in order to reduce the likelihood of damage to walls and other interior improvements. 5) Concrete slabs-on-grade should be provided with properly designed control joints. ACI, AASHTO and other industry groups provide guidelines for proper design and construction concrete slabs-on-grade and associated jointing. The design and construction of such joints should account for cracking as a result of shrinkage, curling, tension, loading, and curing, as well as proposed slab use. Joint layout based on the slab design may require more frequent, additional, or deeper joints, and should reflect the configuration and proposed use of the slab. Particular attention in slab joint layout should be paid to areas where slabs consist of interior corners or curves (e.g., at column blockouts or reentrant corners) or where slabs have high length to width ratios, significant slopes, thickness transitions, high traffic loads, or other unique features. The improper placement or construction of control joints will increase the potential for slab cracking. 6) Interior partitions resting on floor slabs should be provided with slip joints so that if the slabs move, the movement cannot be transmitted to the upper structure. This detail is also important for wallboards and doorframes. Slip joints which will allow 2 inches or more of differential vertical movement should be considered. It may not be practical to construct slip joints capable of accommodating movements of that magnitude. In such case, replacement of the slip joints or re- establishment of slip capacity should be anticipated and incorporated into building design. Accommodation for differential movement also should be made where partitions meet bearing walls. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 12 of 51 7) Post-construction soil movements may not displace slab-on-grade floors and utility lines in the soils beneath them to the same extent. Design of floor penetrations, connections and fixtures should accommodate at least 2 inches of differential movement. 8) Moisture can be introduced into a slab subgrade during construction and additional moisture will be released from the slab concrete as it cures. A properly compacted layer of free-draining gravel, 4 or more inches in thickness, should be placed beneath the slabs. This layer will help distribute floor slab loadings, ease construction, reduce capillary moisture rise, and aid in drainage. The free-draining gravel should contain less than 5 percent material passing the No. 200 Sieve, more than 50 percent retained on the No. 4 Sieve, and a maximum particle size of 2 inches. The capillary break and the drainage space provided by the gravel layer also may reduce the potential for excessive water vapor fluxes from the slab after construction as mix water is released from the concrete. We understand, however, that professional experience and opinion differ with regard to inclusion of a free-draining gravel layer beneath slab-on-grade floors. If these issues are understood by the owner and appropriate measures are implemented to address potential concerns including slab curling and moisture fluxes, then the gravel layer may be deleted. 9) A vapor barrier beneath a building floor slab can be beneficial with regard to reducing exterior moisture moving into the building, through the slab, but can retard downward drainage of construction moisture. Uneven moisture release can result in slab curling. Elevated vapor fluxes can be detrimental to the adhesion and performance of many floor coverings and may exceed various flooring manufacturers’ usage criteria. Per the 2006 ACI Location Guideline, a vapor barrier is required under concrete floors when that floor is to receive moisture-sensitive floor covering and/or adhesives, or the room above that floor has humidity control. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 13 of 51 Therefore, in light of the several, potentially conflicting effects of the use vapor- barriers, the owner and the architect and/or contractor should weigh the performance of the slab and appropriate flooring products in light of the intended building use, etc., during the floor system design process and the selection of flooring materials. Use of a plastic vapor-barrier membrane may be appropriate for some building areas and not for others. In the event a vapor barrier is utilized, it generally should consist of a minimum 15 mil thickness, extruded polyolefin plastic (no recycled content or woven materials), maintain a permeance less than 0.01 perms per ASTM E-96 or ASTM F-1249, and comply with ASTM E-1745 (Class “A”). Vapor barriers should be installed in accordance with ASTM E-1643. Polyethylene (“poly”) sheeting (even if 15 mils in thickness which polyethylene sheeting commonly is not) does not meet the ASTM E-1745 criteria and should not, in general, be used as vapor barrier material. It can be torn and/or punctured easily, does not possess necessary tensile strength, becomes brittle, tends to decompose over time, and has a relatively high permeance. Construction Considerations for Slab-on-Grade Floors 10) Loose, soft or otherwise unsuitable materials exposed on the prepared surface on which the floor slab will be cast should be excavated and replaced with properly compacted fill. 11) Concrete floor slabs should be constructed and cured in accordance with applicable industry standards and slab design specifications. 12) All plumbing lines should be carefully tested before operation. Where plumbing lines enter through the floor, a positive bond break should be provided. OBSERVATORY FOUNDATION AND FLOOR SYSTEM (Drilled Pier Foundations) Geotechnical Risk The proposed location of the observatory is underlain by approximately 6 feet of undocumented fill materials and claystone bedrock materials. As stated previously undocumented fills are generally not geotechnically acceptable as they present an unquantifiable potential for heave and settlement. Additionally the claystone Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 14 of 51 materials underlying the proposed observatory location exhibited potentials for post- construction heave that can cause damaging, post-construction, structural movements. This condition, if not mitigated, will affect improvements near the observatory site. Mitigating the expansive materials and/or their effects, the undocumented fills, as well as controlling the surface waters and shallow subsurface moisture changes, are the principal geotechnical design considerations for the site. Specific geotechnical parameters in these regards are provided in subsequent sections of this report. Additional discussion and information regarding these recommendations and the geotechnical risks that they address are provided below. Additionally, it is our understanding that this structure is sensitive to vibration and settlement and a deep foundation system is desirable to mitigate further mitigate these when compared to a shallow foundation. Depth of Wetting The “depth of wetting” (the depth to which foundation soils will gain moisture and experience volume change over the design-life of a structure) estimated for a given site strongly affects the anticipated performance of structures at that site. Based on the data obtained at this site and our experience with similar geotechnical settings, a ‘depth of wetting’ of 20 feet was used to develop geotechnical parameters for foundation system design. ‘Depths of wetting’ of 30, 40 or 70 feet or more have been considered (e.g., Chao and others, 2006)3 and have been encountered locally in the field. Depths of wetting of such magnitudes, however, generally are in unusual geologic conditions such as the Dipping Bedrock Overlay District to the west, or identified forensically in unusual circumstances such as a pipe leak that has remained un-repaired for an extended period. In our experience, such deep ‘depths of wetting’ are considered only rarely in engineering consulting practice in more typical geologic settings in the Colorado Front Range area. GROUND considers a 20-foot depth of wetting to be appropriately conservative for the proposed project. We can consider a more (or less) conservative depth of wetting, however, upon request. Observatory Foundation/Floor System Due to the movement potential in the existing fill materials and the claystone materials encountered at the project site as well as the nature of the observatory structure, it is GROUND’s opinion that the proposed 3 Chao, K-C, D.D. Overton, and J.D. Miller, 2006, The Effects of Site Conditions on the Predicted Time Rate of Heave, Unsaturated Soils 2006, American Society of Civil Engineers, Special Publication No. 147, pp. 2086 – 2097. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 15 of 51 observatory facility be supported on straight-shaft drilled piers advanced into the underlying bedrock and provided with a structural floor system. Additionally, building entryways should be founded similarly so as to reduce the potential for differential movement. Although a drilled pier foundation system (of any length) will not eliminate the risk of post-construction building movement, if the measures outlined in this report are implemented effectively, the likelihood of acceptable building performance to a reasonable degree of engineering certainty will be within local industry standards for construction of a drilled pier foundation system on soils and bedrock of this nature. Based on the conditions encountered in GROUND’s test holes, the assumptions outlined herein, including effective maintenance of site drainage, we estimate likely post- construction movements from heave and/or settlement of drilled pier foundations to be on the order of ½ inch. Observatory Drilled Pier Foundation System Geotechnical Parameters for Drilled Pier Design Based on the results of the field exploration, laboratory testing, and experience, the design criteria presented below should be observed for a straight-shaft, drilled pier foundation system. In our experience it can be beneficial to facilitate construction to use as few pier diameters / types as possible. Note that the minimum dead load and the minimum pier length indicated below were developed to resist the uplift force that the expansive bedrock will exert on the surface of the pier in the zone above the depth of wetting. The minimum length on that basis may or may not be sufficient to provide the necessary axial capacity. The uplift loading also should be used to develop the (minimum) reinforcing steel, as discussed below. 1) Drilled piers should bear in ‘comparatively unweathered’ bedrock underlying the site. For design purposes, ‘comparatively unweathered’ bedrock may be taken to be at and below a depth of approximately 9 feet below existing grades. For bidding purposes, these elevations may vary. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 16 of 51 2) Drilled piers should be at least 18 inches in diameter and should be designed with a maximum length to diameter ratio of 30 to 1. The actual length to diameter ratios should be determined by the structural engineer. 3) Drilled piers should have a minimum length of 30 feet. The actual drilled pier lengths should be determined by the structural engineer based on loading, etc., with further increases in length possibly required by the conditions encountered during installation at each drilled pier location. 4) Drilled piers also should penetrate at least 10 feet into relatively un-weathered bedrock or 3 drilled pier diameters, whichever is greater. Based on the minimum length and bedrock penetration, and taking the top of relatively un-weathered bedrock to be about 9 feet below existing grade, drilled pier lengths on the order of 30 to 32 feet are anticipated to meet the geotechnical criteria. Actual drilled pier lengths commonly will be greater due to structural considerations, conditions in the drilled pier holes, actual depths to relatively un- weathered bedrock, clean out, etc. 5) Drilled piers bearing in relatively un-weathered bedrock at and below depths of 30 feet may be designed for an allowable end bearing pressure of 30,000 psf. The portion of the drilled pier penetrating comparatively un-weathered bedrock may be designed for a skin friction value of 2,250 psf. 100 percent of the skin friction may be used to resist both compressional loads and uplift. However, skin friction above the depth of wetting indicated in the Observatory Foundation and Floor System section of this report, i.e., in the upper 20 feet of the pier should be ignored for axial load resistance. 6) Estimated settlement of properly constructed drilled piers will be low – on the order of ½ inch – to mobilize skin friction. 7) Drilled piers should be designed for a minimum dead load pressure of 6,000 psf based on drilled pier cross-sectional area. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 17 of 51 Where minimum dead load cannot be applied, it will be necessary to increase the drilled pier length beyond the recommended minimum, even where the minimum bedrock penetration has been achieved or exceeded. This can be accomplished by assuming that skin friction on the extended zone acts in the direction to resist uplift. 8) Drilled piers should be reinforced as determined by the structural engineer. At a minimum, drilled piers should be reinforced for their full length to resist the tensile loading created by the swelling soils and bedrock. Tension may be estimated as an uplift skin friction of 1,050 psf applied to the upper 20 feet of each drilled pier. Reinforcement design also should include any deficit between the dead load applied in design and the minimum dead load provided above. 9) A 6-inch or thicker continuous void should be provided beneath grade beams, drilled pier caps, foundation walls, and floor slabs. The void space should be protected from backfill intrusion. 10) Based on the data obtained for this study and our experience with similar sites and conditions, lateral load analysis using the Terzaghi method may take the values tabulated below for the modulus of horizontal subgrade reaction (Kh) to be characteristic of the soils and bedrock underlying the site, based on a simplified soil / bedrock profile. Resistance to lateral loads by deep foundations should be neglected in the upper 3 feet of soils, weather fill or native granular fill soils. Horizontal Modulus Subgrade Reaction (Kh) – Terzaghi Method Material Kh based on Foundation Kh based on Foundation Approximate Depth Range Element Width / Diameter Element Width / Diameter 1.5-Foot Diameter 2-Foot Diameter Overburden Fill and Sand and Clay 3-9 80 tcf 60 tcf Claystone Bedrock 9+ feet 240 tcf 180 tcf Note that the Kh values tabulated above are dependent on deep foundation element width or diameter. If values for other widths / diameters are required, please contact this office. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 18 of 51 11) Penetration of comparatively unweathered bedrock in drilled pier shafts should be roughened artificially to assist the development of peripheral shear between the drilled pier and bedrock. Artificially roughening of drilled pier holes should consist of installing shear rings 3 inches high and 2 inches deep in the portion of each drilled pier penetrating comparatively unweathered bedrock and below a depth of 20 feet. The shear rings should be installed 18 inches on centers. However, the specifications should allow a geotechnical engineer to waive the requirement for shear rings depending on the conditions actually encountered in individual drilled pier holes. 12) Groups of closely spaced drilled piers placed to support concentrated loads will require an appropriate reduction of the estimated capacities. Reduction of axial capacity generally can be avoided by spacing drilled piers at least 3 diameters center to center. At this spacing or greater, no reduction in axial capacities or horizontal soil modulus values is required. Drilled pier groups spaced less than 3 diameters center to center should be studied on an individual basis to determine the appropriate axial capacity reduction(s). The settlement of closely spaced groups of drilled piers should also be studied on an individual basis. Linear arrays of drilled piers, however, must be spaced at least 8 diameters center to center to avoid reductions in lateral capacity when loaded in line with the array (parallel to the line connecting the drilled pier centers). Linear arrays of drilled piers spaced more closely than 8 diameters center to center should be studied to determine the appropriate lateral capacity reductions in that direction. Refer to Figures 6 and 7 for additional information regarding reductions in lateral and axial capacity for closely spaced caissons Drilled Pier Construction The following should be considered during the construction of drilled pier foundations. 13) The depth of comparatively unweathered bedrock should be determined in the field at each drilled pier location and may differ from other information provided herein. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 19 of 51 14) Lenses or beds of relatively soft bedrock, including coal or lignite seams, (not suitable for foundation support) may be encountered in the bedrock materials. Such circumstances may result in lengthening the drilled piers. 15) The bedrock beneath the site was hard to very hard and resistant, particularly with depth. The pier-drilling contractor should mobilize equipment of sufficient size and operating capability to achieve the design lengths and bedrock penetration. If refusal is encountered in these materials, a geotechnical engineer should be retained to evaluate the conditions to establish whether true refusal has been met with adequate drilling equipment. 16) Groundwater was encountered in test hole 10 at a depth of approximately 22 feet below existing grade the time of drilling. Additionally, groundwater was observed as shallow as 4 feet below the existing grade at the proposed observatory location in the test holes advanced for the Health Care Career Center to the northwest. Groundwater, combined with granular soils, often results in caving during pier installation. Seating of the casing in the upper layers of the bedrock may not create positive cutoff of water infiltration. The contractor should be prepared to address this condition. 17) In no case should concrete be placed in more than 3-inches of water, unless placed through an approved tremie method. The proposed concrete placement method should be discussed during the pre-construction meeting by the Project Team. 18) Where groundwater and unconsolidated soils and/or caving bedrock materials are encountered, the installation procedure of drilled piers can be a concern. Commonly in these conditions, the drilling contractor utilizes casing and slurry during excavation of the drilled pier holes, which may adversely affect the axial and/or lateral capacities of the completed drilled piers. During casing withdrawal, the concrete should have sufficient slump and must be maintained with sufficient head above groundwater levels to displace the water or slurry fully to prevent the creation of voids in the drilled pier. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 20 of 51 Because of these considerations, the drilling contractor should submit a written procedure addressing the use of casing, slurry, and concrete placement prior to commencement of drilled pier installation. 19) Drilled pier holes should be properly cleaned prior to placement of concrete. 20) Concrete utilized in the drilled piers should be a fluid mix with sufficient slump so that it will fill the void between reinforcing steel and the drilled pier hole wall, and inhibit soil, water, and slurry from contaminating the concrete. The concrete should be designed with a minimum slump of no less than 5 inches. 21) Concrete should be placed by an approved method to minimize mix segregation. 22) Concrete should be placed in a drilled pier on the same day that it is drilled. Failure to place concrete the day of drilling may result in a requirement for lengthening the drilled pier. The presence of groundwater or caving soils may require that concrete be placed immediately after the pier hole drilling is completed. 23) The contractor should take care to prevent enlargement of the excavation at the tops of drilled piers, which could result in “mushrooming” of the drilled pier top. 24) Sonic integrity testing (sonic echo or cross-hole sonic) can be performed at the discretion of the structural engineer to assess the effectiveness of the drilled pier construction methods and to check any suspect piers. Additional information on sonic integrity testing can be provided upon request. Observatory Structural Floor System Structural floors should be supported on grade beams and straight-shaft drilled piers in the same manner as the building structure. Requirements for the number and position of additional piers to support the floors will depend upon the span, design load, and structural design, and should be developed by the Structural Engineer. Geotechnical recommendations for design and installation of drilled piers are provided in the Observatory Drilled Pier Foundation System section of this report. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 21 of 51 Crawl Space Structural floors should be constructed to span above a well-ventilated crawl space permitting utility lines to be installed above the swelling materials. The crawl space should be adequately sized to allow access to and maintenance of utility piping and have a minimum clearance of 24 inches. Piping connections through floors, grade beams, or foundation walls should allow for differential movement between the piping and the structural element through which the piping is penetrating. Additionally, prior to or during the construction of the planned addition may be an opportune time to assess the ventilation and general condition of crawl space beneath the existing gym. This space should also be provided with adequate ventilation similar to that of the new crawl space. A vapor barrier meeting ASTM E-1745 (Class “A”) should be considered for installation below all structurally supported floors and if utilized, should be properly attached/sealed to foundation walls/drilled piers above the void material. The sheet material should not be attached to horizontal surfaces such that condensate might drain to wood or corrodible metal surfaces. Use of polyethylene (“poly”) sheeting as a vapor barrier is not recommended. Polyethylene (“poly”) sheeting (even if 15 mils in thickness which polyethylene sheeting commonly is not) does not meet the ASTM E-1745 criteria and is not recommended for use as vapor barrier material. It can be easily torn and/or punctured, does not possess the necessary tensile strength, gets brittle, tends to decompose over time, and has a relatively high permeance. New buildings generally lack ventilation due primarily to systematic efforts to construct air-tight, energy-efficient structures. Therefore, areas such as crawl spaces beneath structural floors are typically areas of elevated humidity which never completely dry. This condition can be aggravated in some locations by shallow groundwater or a perched groundwater condition, which can result in saturated soils within several feet of the finished building pad grade. Persistently warm, humid conditions in the presence of cellulose, which is found in many typical construction materials, creates an ideal environment for the growth of molds, fungi and mildew. Published data suggest links between molds and illnesses. Therefore, GROUND recommends that crawl spaces beneath structural floors be provided with adequate, active ventilation systems or other active mechanisms such as specially designed HVAC systems to reduce the potential Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 22 of 51 for mold, fungus and mildew growth. Crawl spaces should be inspected periodically so that remedial measures can be taken in a timely manner, should mold, fungus or mildew be present and require removal. The Owner must be willing to accept the risks of potential mold, fungus and mildew growth when electing to utilize a structural floor system. Additionally, the contractor is solely responsible for the means and methods during construction including adequate ventilation, and any observation or testing performed during construction does not relieve the contractor of that responsibility. All plumbing lines should be carefully tested before operation. Where utility lines enter through the floor, positive bond breaks should be provided. Utility lines can be displaced by soils and bedrock movements, which are not reflected in the building. Design and installation of associated fixtures should accommodate this potential differential movement, which could be on the order of 8 inches or more and should allow for repair / maintenance. Slab-on-void Alternative Based on GROUND’s experience with similar projects, as an alternate floor system, the proposed floor could be constructed as a structural slab on void form in lieu of a structural floor system over a ventilated crawl space. In the event a structural slab on void form is utilized, a minimum void form thickness of 6 inches should be utilized. Greater void thickness may accommodate increased heave movement. The Client/Owner should be aware that to our knowledge, there is no floor system that will provide the same tolerance for floor movements as would be provided by a structural floor system placed over a well-ventilated crawl space. Please note that by utilizing a structural floor spanning above a crawl space, as indicated previously, this would permit utility lines to be installed (hung) above the swelling soils and bedrock. GROUND would anticipate that utilities placed in soil trenches beneath a structural slab on void may be subjected to these expansive materials. Piping connections through the floor should allow for differential movement between the piping and floor system (flexible). All plumbing lines should be carefully tested before operation. Where utility lines enter through the floor, positive bond breaks should be provided. Utility lines can be displaced by soil and bedrock movements, which are not reflected in the building. Design and installation of associated fixtures should Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 23 of 51 accommodate this potential differential movement. Previously, we stated that entryway floor slabs should also be constructed as structural floors. In the event this is not to be the case, again, the Client/Owner should be aware that these elements may also be subjected to expansive materials and may experience significant structural movements. LATERAL EARTH PRESSURES The at-rest, active, and passive conditions for the on-site backfill is summarized on the table below. Base friction may be combined with passive earth pressure if the foundation is in a drained condition. The values for the on-site material in the upper 10 feet provided in the table below were approximated utilizing a unit weight of 127 pcf and a phi angle of 27 degrees. Lateral Earth Pressures (Equivalent Fluid Unit Weights) Material Type Water Condition At-Rest (pcf) Active (pcf) Passive(pcf) Friction Coefficient CDOT Class 1 Structure Fill Drained 55 37 400 (max. 4,000 psf) 0.45 On-Site Backfill Drained 70 48 300(max. 3,000 psf) 0.34 The upper 1 foot of embedment should be neglected for passive resistance, however. Where this passive soil pressure is used to resist lateral loads, it should be understood that significant lateral strains will be required to mobilize the full value indicated above, likely 1 inch or more. A reduced passive pressure can be used for reduced anticipated strains, however. The lateral earth pressures indicated above are for a horizontal upper backfill slope. The additional loading of an upward sloping backfill as well as loads from traffic, stockpiled materials, etc., should be included in the wall/shoring design. GROUND can provide the adjusted lateral earth pressures when the additional loading conditions and site grading are clearly defined. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 24 of 51 WATER-SOLUBLE SULFATES The concentration of water-soluble sulfates measured in selected samples retrieved from the test holes ranged up to 0.02 percent by weight (see Table 2). Such a concentration of water-soluble sulfates represents a negligible degree of sulfate attack on concrete exposed to these materials. Degrees of attack are based on the scale of 'negligible,' 'moderate,' 'severe' and 'very severe' as described in the “Design and Control of Concrete Mixtures,” published by the Portland Cement Association (PCA). The Colorado Department of Transportation (CDOT) utilizes a corresponding scale with 4 classes of severity of sulfate exposure (Class 0 to Class 3) as described in the published table below. REQUIREMENTS TO PROTECT AGAINST DAMAGE TO CONCRETE BY SULFATE ATTACK FROM EXTERNAL SOURCES OF SULFATE Severity of Sulfate Exposure Water-Soluble Sulfate (SO4) In Dry Soil (%) Sulfate (SO4) In Water (ppm) Water Cementitious Ratio (maximum) Cementitious Material Requirements Class 0 0.00 to 0.10 0 to 150 0.45 Class 0 Class 1 0.11 to 0.20 151 to 1500 0.45 Class 1 Class 2 0.21 to 2.00 1501 to 10,000 0.45 Class 2 Class 3 2.01 or greater 10,001 or greater 0.40 Class 3 Based on these data no special sulfate-resistant cement appears necessary in project concrete. SOIL CORROSIVITY The degree of risk for corrosion of metals in soils commonly is considered to be in two categories: corrosion in undisturbed soils and corrosion in disturbed soils. The potential for corrosion in undisturbed soil is generally low, regardless of soil types and conditions, because it is limited by the amount of oxygen that is available to create an electrolytic cell. In disturbed soils, the potential for corrosion typically is higher, but is strongly affected by soil chemistry and other factors. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 25 of 51 A preliminary corrosivity analysis was performed to provide a general assessment of the potential for corrosion of ferrous metals installed in contact with earth materials at the site, based on the conditions existing at the time of GROUND’s evaluation. Soil chemistry and physical property data including pH, and sulfides content were obtained. Test results are summarized on Table 2. pH Where pH is less than 4.0, soil serves as an electrolyte; the pH range of about 6.5 to 7.5 indicates soil conditions that are optimum for sulfate reduction. In the pH range above 8.5, soils are generally high in dissolved salts, yielding a low soil resistivity (AWWA, 2010). Testing indicated pH values of approximately 8.5 and 8.4. Reduction-Oxidation testing indicated negative potentials: approximately -116 and -111 millivolts. Such low potentials typically create a more corrosive environment. Sulfide Reactivity testing for the presence of sulfides indicated ‘positive’ results. The presence of sulfides in the site soils also suggests a more corrosive environment. Soil Resistivity In order to assess the “worst case” for mitigation planning, samples of materials retrieved from the test holes were tested for resistivity in the in the laboratory, after being saturated with water, rather than in the field. Resistivity also varies inversely with temperature. Therefore, the laboratory measurements were made at a controlled temperature. A measurement of electrical resistivity indicated values of approximately 2,287 and 5,044 ohm-centimeters in samples of the site earth materials. Corrosivity Assessment The American Water Works Association (AWWA, 20104) has developed a point system scale used to predict corrosivity. The scale is intended for protection of ductile iron pipe but is valuable for project steel selection. When the scale equals 10 points or higher, protective measures for ductile iron pipe are suggested. The AWWA scale (Table A.1 Soil-test Evaluation) is presented below. The soil characteristics refer to the conditions at and above pipe installation depth. 4 American Water Works Association ANSI/AWWA C105/A21.5-05 Standard.

We anticipate that drainage at the site after construction will be effective. However, based on the values obtained for the soil parameters, the overburden soils appear to comprise a highly corrosive environment for metals (10.5 points). If additional information are needed regarding soil corrosivity, the American Water Works Association or a Corrosion Engineer should be contacted. It should be noted, however, that changes to the site conditions during construction, such as the import of other soils, Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 27 of 51 or the intended or unintended introduction of off-site water, may significantly alter corrosion potential. EXTERIOR FLATWORK Proper design, drainage, construction, and maintenance of the areas between individual buildings and parking/driveway areas are critical to the satisfactory performance of the project. Sidewalks, entranceway slabs and roofs, fountains, raised planters, and other highly visible improvements commonly are installed within these zones, and distress in or near these improvements is common. Commonly, soil preparation in these areas receives little attention because they fall between the building and pavement (which are typically built with heavy equipment). Subsequent landscaping and hardscape installation often is performed by multiple sub-contractors with light or hand equipment, and over-excavation / soil processing is not performed. Therefore, particular care should be taken by the design team, contractor, and pertinent subcontractors take particular care with regard to proper subgrade preparation around the structure exteriors. Similar to slab-on-grade floors, exterior flatwork and other hardscaping placed on the soils encountered on-site may experience post-construction movements due to volume change of the subsurface soils and the relatively light loads that they impose. Both vertical and lateral soil movements can be anticipated as the soils experience volume change as the moisture content varies. Distress to rigid hardscaping likely will result. The following measures will help to reduce damages to these improvements. Provided the owner understands the risks identified above, the subgrade under exterior flatwork or other (non-building) site improvements should be scarified to a depth of 12 or more inches. The scarified soil should be replaced as properly moisture-conditioned and compacted fill as outlined in the Project Earthwork section of this report. Prior to placement of flatwork, a proof roll should be performed to identify areas that exhibit instability and deflection. The soils in these areas should be removed and replaced with properly compacted fill or stabilized. Flatwork should be provided with effective control joints. Increasing the frequency of joints may improve performance. ACI recommendations should be followed regarding construction and/or control joints. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 28 of 51 In no case should exterior flatwork extend to under any portion of the building where there is less than 2 inches of vertical clearance between the flatwork and any element of the building. Exterior flatwork in contact with brick, rock facades, or any other element of the building can cause damage to the structure if the flatwork experiences movements. GROUND does not recommend tying of exterior flatwork and/or hardscapes to the building including floor slabs, bearing walls, or columns. The exterior flatwork should be independent and be allowed to move independently from the structure and its components. As discussed in the Surface Drainage section of this report, proper drainage also should be maintained after completion of the project, and re-established as necessary. In no case should water be allowed to pond on or near any of the site improvements or a reduction in performance should be anticipated. Concrete Scaling: Climatic conditions in the project area including relatively low humidity, large temperature changes and repeated freeze – thaw cycles, make it likely that project sidewalks and other exterior concrete will experience surficial scaling or spalling. The likelihood of concrete scaling can be increased by poor workmanship during construction, such as ‘over-finishing’ the surfaces. In addition, the use of de-icing salts on exterior concrete flatwork, particularly during the first winter after construction, will increase the likelihood of scaling. Even use of de-icing salts on nearby roadways, from where vehicle traffic can transfer them to newly placed concrete, can be sufficient to induce scaling. Typical quality control / quality assurance tests that are performed during construction for concrete strength, air content, etc., do not provide information with regard to the properties and conditions that give rise to scaling. We understand that some municipalities require removal and replacement of concrete that exhibits scaling, even if the material was within specification and placed correctly. The contractor should be aware of the local requirements and be prepared to take measures to reduce the potential for scaling and/or replace concrete that scales. In GROUND’s experience, the measures below can be beneficial for reducing the likelihood of concrete scaling. It must be understood, however, that because of the other factors involved, including weather conditions and workmanship, surface damage to concrete can develop, even where all of these measures were followed. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 29 of 51 1) Maintaining a maximum water/cement ratio of 0.45 by weight for exterior concrete mixes. 2) Include Type F fly ash in exterior concrete mixes as 20 percent of the cementitious material. 3) Specify a minimum, 28-day, compressive strength of 4,500 psi for all exterior concrete. 4) Include ‘fibermesh’ in the concrete mix. also may be beneficial for reducing surficial scaling. 5) Cure the concrete effectively at uniform temperature and humidity. This commonly will require fogging, blanketing and/or tenting, depending on the weather conditions. As long as 3 to 4 weeks of curing may be required, and possibly more. 6) Avoid placement of concrete during cold weather so that it is not exposed to freeze-thaw cycling before it is fully cured. 7) Avoid the use of de-icing salts on given reaches of flatwork through the first winter after construction. We understand that commonly it may not be practical to implement some of these measures for reducing scaling due to safety considerations, project scheduling, etc. In such cases, additional costs for flatwork maintenance or reconstruction should be incorporated into project budgets. PROJECT EARTHWORK The earthwork criteria below are based on our interpretation of the geotechnical conditions encountered in the test holes. Where these criteria differ from applicable municipal specifications, e.g., for trench backfill compaction along a public utility line, the latter should be considered to take precedence. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 30 of 51 General Considerations: Site grading should be performed as early as possible in the construction sequence to allow settlement of fills and surcharged ground to be realized to the greatest extent prior to subsequent construction. Prior to earthwork construction, existing concrete, asphalt, vegetation, and other deleterious materials should be removed and disposed of off-site. Relic underground utilities should be abandoned in accordance with applicable regulations, removed as necessary, and properly capped. Topsoil present on-site should not be incorporated into ordinary fills. Instead, topsoil should be stockpiled during initial grading operations for placement in areas to be landscaped or for other approved uses. Existing Fill Soils: Man-made fill materials were encountered in select test holes during subsurface exploration. Complete contents and composition of the man-made fill materials are not known; therefore, some of the excavated man-made fill materials may not be suitable for replacement as backfill. We anticipate that the majority of the fill materials will be suitable for re-use as fill; however, a geotechnical engineer should be retained during site excavations to observe the excavated fill materials and provide recommendations for its suitability for reuse. Drainage During Construction The contractor should take pro-active measures to control surface waters during construction, to direct them away from excavations and into appropriate drainage structures. Wetting of foundation soils during construction can have adverse effects on the performance of the proposed facility. Filled areas should be graded to drain effectively at the end of each work day. Use of Existing Native Soils: Overburden soils that are free of trash, organic material (including all firewood, wood chips, etc.), construction debris, and other deleterious materials are suitable, in general, for placement as compacted fill. Organic materials should not be incorporated into project fills. Fragments of rock, cobbles, and inert construction debris (e.g., concrete or asphalt) larger than 3 inches in maximum dimension will require special handling and/or placement to be incorporated into project fills. In general, such materials should be placed as deeply as possible in the project fills. A Geotechnical Engineer should be Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 31 of 51 consulted regarding appropriate direction for usage of such materials on a case-by-case basis when such materials have been identified during earthwork. Standard parameters that likely will be generally applicable can be found in Section 203 of the current CDOT Standard Specifications for Road and Bridge Construction. Imported Fill Materials: If it is necessary to import material to the site, the imported soils should be free of organic material, and other deleterious materials. Imported material should consist of soils that have less than 50 percent passing the No. 200 Sieve and should have a plasticity index of less than 15. Representative samples of the materials proposed for import should be tested and approved prior to transport to the site. Fill Platform Preparation: Prior to filling, the top 8 to 12 inches of in-place materials on which fill soils will be placed should be scarified, moisture conditioned and properly compacted in accordance with the parameters below to provide a uniform base for fill placement. If over-excavation is to be performed, then these parameters for subgrade preparation are for the subgrade below the bottom of the specified over-excavation depth. If surfaces to receive fill expose loose, wet, soft or otherwise deleterious material, additional material should be excavated, or other measures taken to establish a firm platform for filling. The surfaces to receive fill must be effectively stable prior to placement of fill. General Considerations for Fill Placement: Fill soils should be thoroughly mixed to achieve a uniform moisture content, placed in uniform lifts not exceeding 8 inches in loose thickness, and properly compacted. No fill materials should be placed, worked, rolled while they are frozen, thawing, or during poor/inclement weather conditions. Where soils supporting foundations or on which foundation will be placed are exposed to freezing temperatures or repeated freeze – thaw cycling during construction – commonly due to water ponding in foundation excavations – bearing capacity typically is reduced and/or settlements increased due to the loss of density in the supporting soils. After periods of freezing conditions, the contractor should re-work areas affected by the formation of ice to re-establish adequate bearing support. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 32 of 51 Care should be taken with regard to achieving and maintaining proper moisture contents during placement and compaction. Materials that are not properly moisture conditioned may exhibit pumping, rutting, and deflection at high moisture contents. Compaction areas should be kept separate, and no lift should be covered by another until relative compaction and moisture content within the specified ranges are obtained. Compaction Specifications: Soils that classify as GP, GW, GM, GC, SP, SW, SM, or SC in accordance with the USCS classification system (granular materials) should be compacted to 95 or more percent of the maximum modified Proctor dry density at moisture contents within 2 percent of optimum moisture content as determined by ASTM D1557. Soils that classify as ML or CL should be compacted to 95 or more percent of the maximum standard Proctor density at moisture contents within 2 percent of the optimum moisture content as determined by ASTM D698. Use of Squeegee: Relatively uniformly graded fine gravel or coarse sand, i.e., “squeegee,” or similar materials commonly are proposed for backfilling foundation excavations, utility trenches (excluding approved pipe bedding), and other areas where employing compaction equipment is difficult. In general, GROUND does not recommend this procedure for the following reasons: Although commonly considered “self compacting,” uniformly graded granular materials require densification after placement, typically by vibration. The equipment to densify these materials is not available on many job-sites. Even when properly densified, uniformly graded granular materials are permeable and allow water to reach and collect in the lower portions of the excavations backfilled with those materials. This leads to wetting of the underlying soils and resultant potential loss of bearing support as well as increased local heave or settlement. It is GROUND’s opinion that wherever possible, excavations be backfilled with approved, on-site soils placed as properly compacted fill. Where this is not feasible, use of “Controlled Low Strength Material” (CLSM), i.e., a lean, sand-cement slurry (“flowable fill”) or a similar material for backfilling should be considered. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 33 of 51 Where “squeegee” or similar materials are proposed for use by the contractor, the design team should be notified by means of a Request for Information (RFI), so that the proposed use can be considered on a case-by-case basis. Where “squeegee” meets the project requirements for pipe bedding material, however, it is acceptable for that use. Settlements: Settlements will occur in filled ground, typically on the order of 1 to 2 percent of the fill depth. If fill placement is performed properly and is tightly controlled, in GROUND’s experience the majority (on the order of 60 to 80 percent) of that settlement will typically take place during earthwork construction, provided the contractor achieves the compaction levels recommended herein. The remaining potential settlements likely will take several months or longer to be realized, and may be exacerbated if these fills are subjected to changes in moisture content. GROUND anticipates some degree of post-construction movement/distress as a result of settlement. Cut and Filled Slopes: Permanent site slopes supported by on-site soils up to 5 feet in height may be constructed no steeper than 3 : 1 (horizontal : vertical) in site soils. Minor raveling or surficial sloughing should be anticipated on slopes cut at this angle until vegetation is well re-established. Surface drainage should be designed to direct water away from slope faces. Steeper slope angles and heights may be possible but will require detailed slope stability analysis based on final proposed grading plans. GROUND can be retained to evaluate this on a case by case basis, if needed. EXCAVATION CONSIDERATIONS Excavation Difficulty: Test holes for the subsurface exploration were advanced to the depths indicated on the test hole logs by means of conventional, truck-mounted, geotechnical drilling equipment. We anticipate no significant excavation difficulties in the majority of the site with conventional heavy-duty excavation equipment in good working condition. Excavation Slopes: Temporary, un-shored excavation slopes up to 8 feet in height be cut no steeper than 1.5 (H) to 1 (V) in the on-site soils in the absence of seepage. Some surface sloughing may occur on the slope faces at these angles. Where seepage or flowing groundwater is encountered in shallow project excavations, a Geotechnical Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 34 of 51 Engineer should be retained to evaluate the conditions and provided additional direction, as appropriate. The risk of slope instability will be significantly increased in areas of seepage along excavation slopes. Should site constraints prohibit the use of the recommended slope angles, temporary shoring should be used. The shoring should be designed to resist the lateral earth pressure exerted by structure, traffic, equipment, and stockpiles. GROUND can be retained to provide shoring design upon request. Any excavations in which personnel will be working must comply with all OSHA Standards and Regulations (CFR 29 Part 1926). The contractor’s “responsible person” should evaluate the soil exposed in the excavations as part of the contractor’s safety procedures. GROUND has provided the information above solely as a service to the client, and is not assuming responsibility for construction site safety or the contractor’s activities. Surface Water and Groundwater: Good surface drainage should be provided around temporary excavation slopes to direct surface runoff away from the slope faces. A properly designed swale should be provided at the top of the excavations. In no case should water be allowed to pond at the site. Slopes should be protected against erosion. Erosion along the slopes will result in sloughing and could lead to a slope failure. Groundwater was measured as shallow as 5076 feet in the test holes approximately 4.5 feet below anticipated finished floor elevations. Therefore, groundwater may be encountered in shallow utility trenches A properly designed and installed de-watering system may be required during the construction in these sections of trench. The risk of slope instability will be significantly increased in areas of seepage along the excavation slopes. If seepage is encountered, the slopes should be re-evaluated by a geotechnical engineer. UTILITY LATERAL INSTALLATION AND BACKFILLING The measures and criteria below are based on GROUND’s evaluation of the local, geotechnical conditions. Where the parameters herein differ from applicable municipal requirements, the latter should be considered to govern. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 35 of 51 Pipe Support: The bearing capacity of the site soils appeared adequate, in general, for support of buried utilities. The pipes + contents, typically, are less dense than the soils which will be displaced for installation. Therefore, GROUND anticipates no significant pipe settlements in these materials where properly bedded. Excavation bottoms may expose soft, loose or otherwise deleterious materials, including debris. Firm materials may be disturbed by the excavation process. All such unsuitable materials should be excavated and replaced with properly compacted fill. Areas allowed to pond water will require excavation and replacement with properly compacted fill. The contractor should take particular care to ensure adequate support near pipe joints which are less tolerant of extensional strains. Where thrust blocks are needed, they may be designed utilizing the parameters set forth in the Later Earth Pressures section of this report Trench Backfilling: Some settlement of compacted soil trench backfill materials should be anticipated, even where all the backfill is placed and compacted correctly. Typical settlements are on the order of 1 to 2 percent of fill thickness. However, the need to compact to the lowest portion of the backfill must be balanced against the need to protect the pipe from damage from the compaction process. Some thickness of backfill may need to be placed at compaction levels lower than recommended or specified (or smaller compaction equipment used together with thinner lifts) to avoid damaging the pipe. Protecting the pipe in this manner can result in somewhat greater surface settlements. Therefore, although other alternatives may be available, the following options are presented for consideration: Controlled Low Strength Material: Because of these limitations, we recommend backfilling the entire depth of the trench (both bedding and common backfill zones) with “controlled low strength material” (CLSM), i.e., a lean, sand-cement slurry, “flowable fill,” or similar material along all trench alignment reaches with low tolerances for surface settlements. We recommend that CLSM used as pipe bedding and trench backfill exhibit a 28-day unconfined compressive strength between 50 to 150 psi so that re-excavation is not unusually difficult. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 36 of 51 Placement of the CLSM in several lifts or other measures likely will be necessary to avoid ‘floating’ the pipe. Measures also should be taken to maintain pipe alignment during CLSM placement. Compacted Soil Backfilling: Where compacted soil backfilling is employed, using the site soils or similar materials as backfill, the risk of backfill settlements entailed in the selection of this higher risk alternative must be anticipated and accepted by the Client/Owner. We anticipate that the on-site soils excavated from trenches will be suitable, in general, for use as common trench backfill within the above-described limitations. Backfill soils should be free of vegetation, organic debris and other deleterious materials. Fragments of rock, cobbles, and inert construction debris (e.g., concrete or asphalt) coarser than 3 inches in maximum dimension should not be incorporated into trench backfills. If it is necessary to import material for use as backfill, the imported soils should meet the requirements set for in the Project Earthwork section of this report. Representative samples of the materials proposed for import should be tested and approved prior to transport to the site. Soils placed for compaction as trench backfill should be conditioned to a relatively uniform moisture content, placed and compacted in accordance with the parameters in the Project Earthwork section of this report. Pipe Bedding: Pipe bedding materials, placement and compaction should meet the specifications of the pipe manufacturer and applicable municipal standards. Bedding should be brought up uniformly on both sides of the pipe to reduce differential loadings. As discussed above, we recommend the use of CLSM or similar material in lieu of granular bedding and compacted soil backfill where the tolerance for surface settlement is low. (Placement of CLSM as bedding to at least 12 inches above the pipe can protect the pipe and assist construction of a well-compacted conventional backfill, although possibly at an increased cost relative to the use of conventional bedding.) If a granular bedding material is specified, GROUND recommends that with regard to potential migration of fines into the pipe bedding, design and installation follow ASTM Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 37 of 51 D2321. If the granular bedding does not meet filter criteria for the enclosing soils, then non-woven filter fabric (e.g., Mirafi® 140N, or the equivalent) should be placed around the bedding to reduce migration of fines into the bedding which can result in severe, local surface settlements. Where this protection is not provided, settlements can develop/continue several months or years after completion of the project. In addition, clay or concrete cut-off walls should be installed to interrupt the granular bedding section to reduce the rates and volumes of water transmitted along the utility alignment which can contribute to migration of fines. If granular bedding is specified, the contractor should not anticipate that significant volumes of shallow on-site soils may be suitable for that use. Materials proposed for use as pipe bedding should be tested for suitability prior to use. Imported materials should be tested and approved prior to transport to the site. SURFACE DRAINAGE The site soils are relatively stable with regard to moisture content – volume relationships at their existing moisture contents. Other than the anticipated, post-placement settlement of fills, post-construction soil movements will result primarily from the introduction of water into the soils underlying the proposed structure, hardscaping and pavements. Based on the site surface and subsurface conditions encountered in this study, we do not anticipate a rise in the local water table sufficient to approach grade beam or floor elevations. Therefore, wetting of the soils likely will result from infiltrating surface waters (precipitation, irrigation, etc.), and water flowing along constructed pathways such as bedding in utility pipe trenches. The following drainage measures should be followed both for during construction and as part of project design. The facility should be observed periodically to evaluate the surface drainage and identify areas where drainage is ineffective. Routine maintenance of site drainage should undertaken throughout the design life of the proposed facility. If these measures are not implemented and maintained effectively, the movement estimates provided in this report could be exceeded. 1) Wetting or drying of the underslab or foundation bearing areas should be avoided during and after construction. Permitting increases/variations in moisture to the Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 38 of 51 adjacent or supporting soils may result in increased total and/or differential movements. 2) Positive surface drainage measures should be provided and maintained to reduce water infiltration into foundation soils. The ground surface surrounding the exterior of each building should be sloped to drain away from the foundation in all directions. A minimum slope of 12 inches in the first 10 feet should be constructed in the areas not covered with pavement or concrete slabs, or a minimum of 3 percent in the first 10 feet in the areas covered with pavement or concrete slabs. Reducing the slopes to comply with ADA requirements or other reasons may be necessary but may result in an increased potential for moisture infiltration and subsequent volume change of the underling soils. In no case should water be allowed to pond near or adjacent to foundation elements, hardscaping, etc. 3) Drainage also should be established to direct water away from sidewalks and other hardscaping as well as utility trench alignments which are not tolerant of moisture-volume changes in the underlying soils or flow of infiltrating water. The ground surface near foundation elements should be able to convey water away readily. Cobbles or other materials that tend to act as baffles and restrict surface flow should not be used to cover the ground surface near the foundations. Where the ground surface does not convey water away readily, additional post- construction movements and distress should be anticipated. 4) In GROUND’s experience, it is common during construction that in areas of partially completed paving or hardscaping, bare soil behind curbs and gutters, and utility trenches, water is allowed to pond after rain or snow-melt events. Wetting of the subgrade can result in loss of subgrade support and increased settlements / increase heave. By the time final grading has been completed, significant volumes of water can already have entered the subgrade, leading to Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 39 of 51 subsequent distress and failures. The contractor should maintain effective site drainage throughout construction so that water is directed into appropriate drainage structures. In no case should water be permitted to pond adjacent to or on sidewalks, hardscaping, or other improvements as well as utility trench alignments, which are likely to be adversely affected by moisture-volume changes in the underlying soils or flow of infiltrating water. 5) Roof downspouts and drains, if used, should discharge well beyond the perimeter of the structure foundation, or be provided with positive conveyance off-site for collected waters. If roof downspouts and drains are not used, then surface drainage design should anticipate concentrated volumes of water adjacent to the buildings. 6) Irrigation water – both that applied to landscaped areas and over-spray – commonly is a significant cause of distress to improvements. Where (near-) saturated soil conditions are sustained, distress to nearby improvements should be anticipated. To reduce to potential for such distress, vegetation requiring watering should be located 10 or more feet from the building perimeter, flatwork, or other improvements. Irrigation sprinkler heads should be deployed so that applied water is not introduced near or into foundation/subgrade soils. Landscape irrigation should be limited to the minimum quantities necessary to sustain healthy plant growth. Use of drip irrigation systems can be beneficial for reducing over-spray beyond planters. Drip irrigation also can be beneficial for reducing the amounts of water introduced to building foundation soils, but only if the total volumes of applied water are controlled with regard to limiting that introduction. Controlling rates of moisture increase beneath the foundations, floors and other improvements should take higher priority than minimizing landscape plant losses. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 40 of 51 Where plantings are desired within 10 feet of the building, plants should be placed in water-tight planters, constructed either in-ground or above-grade, to reduce moisture infiltration in the surrounding subgrade soils. Planters should be provided with positive drainage and landscape underdrains. As an alternative involving only a limited increase in risk, the use of water-tight planters may be replaced by local shallow underdrains beneath the planter beds. 7) Plastic membranes should not be used to cover the ground surface near the building without careful consideration of other components of project drainage. Plastic membranes can be beneficial to directing surface waters away from the building and toward drainage structures. However, they effectively preclude evaporation and transpiration of shallow soil moisture. Therefore, soil moisture tends to increase beneath a continuous membrane. Where plastic membranes are used, additional shallow, subsurface drains should be installed. Perforated “weed barrier” membranes that allow ready evaporation from the underlying soils may be used. SUBSURFACE DRAINAGE As a component of project civil design, properly functioning, subsurface drain systems (underdrains) can be beneficial for collecting and discharging saturated subsurface waters. Underdrains will not collect water infiltrating under unsaturated (vadose) conditions, or moving via capillarity, however. In addition, if not properly constructed and maintained, underdrains can transfer water into foundation soils, rather than remove it. This will tend to induce heave or settlement of the subsurface soils, and may result in distress. Underdrains can, however, provide an added level of protection against relatively severe post-construction movements by draining saturated conditions near individual structures should they arise, and limiting the volume of wetted soil. Professional opinion varies regarding the potential benefits relative to the cost of an underdrain system. Therefore, the owner and the design team and contractor should assess the net benefit of an underdrain system as a component of overall project drainage. (GROUND does not specifically recommend underdrains at this site with the exception of below grade levels.) Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 41 of 51 If, however, below-grade or partially below-grade level(s) are incorporated into project design, then an underdrain system should be included to protect those portions of the building. Damp-proofing should be applied to the exteriors of below-grade elements. The provision of Tencate MiraFi® G-Series backing (or comparable wall drain provisions) on the exteriors of (some) below-grade elements may be appropriate, depending on the intended use. If a (partially) below-grade level is limited in extent, the underdrain system, etc., may be local to that area. Geotechnical Parameters for Underdrain Design: Where an underdrain system is included in project drainage design, it should be designed in accordance with the parameters below. The actual underdrain layout, outlets, and locations should be developed by a civil engineer. An underdrain system should be tested by the contractor after installation and after placement and compaction of the overlying backfill to verify that the system functions properly. 1) An underdrain system for a building should consist of perforated, rigid, PVC collection pipe at least 4 inches in diameter, non-perforated, rigid, PVC discharge pipe at least 4 inches in diameter, free-draining gravel, and filter fabric, as well as a waterproof membrane. 2) The free-draining gravel should contain less than 5 percent passing the No. 200 Sieve and more than 50 percent retained on the No. 4 Sieve, and have a maximum particle size of 2 inches. Each collection pipe should be surrounded on the sides and top (only) with 6 or more inches of free-draining gravel. 3) The gravel surrounding the collection pipe(s) should be wrapped with filter fabric (MiraFi 140N® or the equivalent) to reduce the migration of fines into the drain system. 4) The waterproof membrane should underlie the gravel and pipe, and be attached to the foundation grade beam or stem wall. 5) The underdrain system should be designed to discharge at least 5 gallons per minute of collected water. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 42 of 51 6) The high point(s) for the collection pipe flow lines should be below the lowest foundation bearing elevation. Multiple high points can be beneficial to reducing the depths to which the system would be installed. The collection and discharge pipe for the underdrain system should be laid on a slope sufficient for effective drainage, but a minimum of 1 percent. (Flatter gradients may be used but will convey water less efficiently and entail an increased risk of local post-construction movements.) Pipe gradients also should be designed to accommodate at least 1 inch of differential movement after installation along a 50-foot run. 7) Underdrain ‘clean-outs’ should be provided at intervals of no more than 100 feet to facilitate maintenance of the underdrains. Clean-outs also should be provided at collection and discharge pipe elbows of 60 degrees or more. 8) The underdrain discharge pipes should be connected to one or more sumps from which water can be removed by pumping, or to outlet(s) for gravity discharge. We suggest that collected waters be discharged directly into the storm sewer system, if possible. PAVEMENT SECTIONS A pavement section is a layered system designed to distribute concentrated traffic loads to the subgrade. Performance of the pavement structure is directly related to the physical properties of the subgrade soils and traffic loadings. The standard care of practice in pavement design describes the flexible pavement section as a “20-year” design pavement: however, most flexible pavements will not remain in satisfactory condition without routine maintenance and rehabilitation procedures performed throughout the life of the pavement. Pavement designs for the private pavements were developed in general accordance with the design guidelines and procedures of the American Association of State Highway and Transportation Officials (AASHTO). Subgrade Materials Based on the results of our field exploration and laboratory testing, the majority of potential pavement subgrade materials classify as sandy clay soils. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 43 of 51 Based on our experience at similar sites, an R-Value of 5 was estimated for the likely on- site pavement subgrade materials. An R-Value of 5 converts to a resilient modulus of 3,025 psi based on CDOT correlation tables. It is important to note that significant decreases in soil support have been observed as the moisture content increases above the optimum. Pavements that are not properly drained may experience a loss of the soil support and subsequent reduction in pavement life. Anticipated Traffic Based on our experience with similar projects an equivalent 18-kip daily load application (EDLA) value of 5 was assumed for the general parking areas, an EDLA value of 10 was assumed for light vehicle drive lanes. The EDLA values of 5 and 10 were converted to equivalent 18-kip single axle load (ESAL) values of 36,500 and 73,000 respectively for a 20-year design life. If anticipated traffic loadings differ significantly from these assumed values, GROUND should be notified to re-evaluate the pavement recommendations below. Pavement Sections The soil resilient modulus and the ESAL values were used to determine the required design structural number for the project pavements. The required structural number was then used to develop the pavement sections. Pavement designs were based on the DARWin™ computer program that solves the 1993 AASHTO pavement design equations. A Reliability Level of 80 percent was utilized to develop the pavement sections, together with a Serviceability index loss of 2.5. An overall standard of deviation of 0.44 also was used. Structural coefficients of 0.44 and 0.11 were used for hot bituminous asphalt and aggregate base course, respectively. The resultant minimum pavement sections that should be used at the facility are tabulated below. Minimum Pavement Sections Location Full Depth Asphalt Composite Section (inches Asphalt) (inches Asphalt / inches ABC) Parking Areas 6.0 4.0 / 8 Light Vehicle Drive Lanes 6.5 4.5 / 8 ABC = Aggregate base course, PCCP = Portland cement concrete pavement Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 44 of 51 Heavy traffic areas/routes serving the facility that impose high stress on the pavement such as trash collection areas or where trucks or tractor-trailers start, stop, or turn sharply such as loading dock areas should be provided with rigid pavements consisting of 6.5 or more inches of portland cement concrete underlain by 6 or more inches of properly compacted CDOT Class 5 or 6 Aggregate Base Course. (An equivalent composite flexible section for these areas would not perform as well as the concrete section where heavy vehicles are parked, stop suddenly, turn repeatedly, etc.) Pavement Materials Asphalt pavement should consist of a bituminous plant mix composed of a mixture of aggregate and bituminous material. Asphalt mixture(s) should meet the requirements of a job-mix formula established by a qualified engineer and applicable local municipality design requirements. Aggregate base material should meet the criteria of CDOT Class 5 or 6 Aggregate Base Course. Base course should be placed in and compacted in accordance with the standards in the Project Earthwork section of this report. Concrete pavements should consist of a plant mix composed of a mixture of aggregate, Portland cement and appropriate admixtures meeting the requirements of a job-mix formula established by a qualified engineer and applicable local municipality design requirements. Concrete should have a minimum modulus of rupture of third point loading of 650 psi. Normally, concrete with a 28-day compressive strength of 4,500 psi should develop this modulus of rupture value. The concrete should be air-entrained with approximately 6 percent air and should have a minimum cement content of 6 sacks per cubic yard. Maximum allowable slump should be 4 inches for hand-placed concrete. Machine-placed concrete may require a lower slump. These concrete mix design criteria should be coordinated with other project requirements including any criteria for sulfate resistance presented in the Water-Soluble Sulfates section of this report. To reduce surficial spalling resulting from freeze-thaw cycling, we suggest that pavement concrete meet the requirements of CDOT Class P concrete. In addition, the use of de-icing salts on concrete pavements during the first winter after construction will increase the likelihood of the development of scaling. Placement of flatwork concrete during cold weather so that it is exposed to freeze-thaw Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 45 of 51 cycling before it is fully cured also increases its vulnerability to scaling. Concrete placing during cold weather conditions should be blanketed or tented to aid in curing. Concrete pavements should contain sawed or formed joints. CDOT and various industry groups provide guidelines for proper design and concrete construction and associated jointing. In areas of repeated turning stresses the concrete pavement joints should be fully tied and doweled. Example layouts for joints, as well as ties and dowels, that may be applicable can be found in CDOT’s M standards, found at the CDOT website: http://www.dot.state.co.us/DesignSupport/. PCA, ACI and ACPA publications also provide useful guidance in these regards. Subgrade Preparation Shortly before paving, the pavement subgrade should be excavated and/or scarified to a minimum depth of 12 inches, moisture-conditioned and properly re-compacted. Subgrade preparation should extend the full width of the pavement from back-of-curb to back-of-curb. The subgrade for sidewalks and other project hardscaping also should be prepared in the same manner. Criteria and standards for fill placement and compaction are provided in the Project Earthwork section of this report. The contractor should be prepared either to dry the subgrade materials or moisten them, as needed, prior to compaction. Localized stabilization efforts such as chemical stabilization or removal and replacement with aggregate base may be used in areas that do not stabilize with conventional moisture- density treatment. Where adequate drainage cannot be achieved or maintained, excavation and replacement should be undertaken to a greater depth, in addition to the edge drains discussed below. Proof Rolling Immediately prior to paving, the subgrade should be proof rolled with a heavily loaded, pneumatic tired vehicle. Areas that show excessive deflection during proof rolling should be excavated and replaced and/or stabilized. Areas allowed to pond prior to paving will require significant re-working prior to proof-rolling. Establishment of a firm paving platform (as indicated by proof rolling) is an additional requirement beyond proper fill placement and compaction. It is possible for soils to be compacted within the Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 46 of 51 limits recommended in the Project Earthwork section of this report and fail proof rolling, particularly in the upper range of indicated moisture contents. Additional Considerations The collection and diversion of surface drainage away from paved areas is extremely important to satisfactory performance of the pavements. The subsurface and surface drainage systems should be carefully designed to ensure removal of the water from paved areas and subgrade soils. Allowing surface waters to pond on pavements will cause premature pavement deterioration. Where topography, site constraints or other factors limit or preclude adequate surface drainage, pavements should be provided with edge drains to reduce loss of subgrade support. The long-term performance of the pavement also can be improved greatly by proper backfilling and compaction behind curbs, gutters, and sidewalks so that ponding is not permitted and water infiltration is reduced. Landscape irrigation in planters adjacent to pavements and in “island” planters within paved areas should be carefully controlled or differential heave and/or rutting of the nearby pavements will result. Drip irrigation systems are recommended for such planters to reduce over-spray and water infiltration beyond the planters. Enclosing the soil in the planters with plastic liners and providing them with positive drainage also will reduce differential moisture increases in the surrounding subgrade soils. In our experience, infiltration from planters adjacent to pavements is a principal source of moisture increase beneath those pavements. This wetting of the subgrade soils from infiltrating irrigation commonly leads to loss of subgrade support for the pavement with resultant accelerating distress, loss of pavement life and increased maintenance costs. This is particularly the case in the later stages of project construction after landscaping has been emplaced but heavy construction traffic has not ended. Heavy vehicle traffic over wetted subgrade commonly results in rutting and pushing of flexible pavements, and cracking of rigid pavements. Where the subgrade soils are expansive, wetting also typically results in increased pavement heave. In relatively flat areas where design drainage gradients necessarily are small, subgrade settlement or heave can obstruct proper drainage and yield increased infiltration, exaggerated distress, etc. (These considerations apply to project flatwork, as well.) Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 47 of 51 Also, GROUND’s experience indicates that longitudinal cracking is common in asphalt- pavements generally parallel to the interface between the asphalt and concrete structures such as curbs, gutters or drain pans. This of this type is likely to occur even where the subgrade has been prepared properly and the asphalt has been compacted properly. The anticipated traffic loading does not include excess loading conditions imposed by heavy construction vehicles. Consequently, heavily loaded concrete, lumber, and building material trucks can have a detrimental effect on the pavement. GROUND recommends that an effective program of regular maintenance be developed and implemented to seal cracks, repair distressed areas, and perform thin overlays throughout the life of the pavements. Most pavements will not remain in satisfactory condition and achieve their “design lives” without regular maintenance and rehabilitation procedures performed throughout the life of the pavement. Maintenance and rehabilitation measures preserve, rather than improve, the structural capacity of the pavement structure. Therefore, GROUND recommends that an effective program of regular maintenance be developed and implemented to seal cracks, repair distressed areas, and perform thin overlays throughout the lives of the pavements. The greatest benefit of pavement overlaying will be achieved by overlaying sound pavements that exhibit little or no distress. Crack sealing should be performed at least annually and a fog seal/chip seal program should be performed on the pavements every 3 to 4 years. After approximately 8 to 10 years after construction, patching, additional crack sealing, and asphalt overlay may be required. Prior to overlays, it is important that all cracks be sealed with a flexible, rubberized crack sealant in order to reduce the potential for propagation of the crack through the overlay. If actual traffic loadings exceed the values used for development of the pavement sections, however, pavement maintenance measures will be needed on an accelerated schedule. CLOSURE AND LIMITATIONS Geotechnical Review The author of this report or a GROUND principal should be retained to review project plans and specifications to evaluate whether they comply with Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 48 of 51 the intent of the measures discussed in this report. The review should be requested in writing. The geotechnical conclusions and parameters presented in this report are contingent upon observation and testing of project earthwork by representatives of GROUND. If another geotechnical consultant is selected to provide materials testing, then that consultant must assume all responsibility for the geotechnical aspects of the project by concurring in writing with the parameters in this report, or by providing alternative parameters. Materials Testing Front Range Community College should consider retaining a geotechnical engineer to perform materials testing during construction. The performance of such testing or lack thereof, however, in no way alleviates the burden of the contractor or subcontractor from constructing in a manner that conforms to applicable project documents and industry standards. The contractor or pertinent subcontractor is ultimately responsible for managing the quality of his work; furthermore, testing by the geotechnical engineer does not preclude the contractor from obtaining or providing whatever services that he deems necessary to complete the project in accordance with applicable documents. Limitations This report has been prepared for Front Range Community College as it pertains to design of the proposed Health Care Career Center as described herein. It should not be assumed to contain sufficient information for other parties or other purposes. The Client has agreed to the terms, conditions, and liability limitations outlined in our agreement between Front Range Community College and GROUND. Reliance upon our report is not granted to any other potential owner, contractor, or lender. Requests for third-party reliance should be directed to GROUND in writing; granting reliance by GROUND is not guaranteed. In addition, GROUND has assumed that project construction will commence by Spring / Summer 2019. Any changes in project plans or schedule should be brought to the attention of a geotechnical engineer, in order that the geotechnical conclusions in this report may be re-evaluated and, as necessary, modified. The geotechnical conclusions in this report were based on subsurface information from a limited number of exploration points, as shown in Figure 1, as well as the means and Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 49 of 51 methods described herein. Subsurface conditions were interpolated between and extrapolated beyond these locations. It is not possible to guarantee the subsurface conditions are as indicated in this report. Actual conditions exposed during construction may differ from those encountered during site exploration. In addition, a contractor who obtains information from this report for development of his scope of work or cost estimates does so solely at his own risk and may find the geotechnical information in this report to be inadequate for his purposes or find the geotechnical conditions described herein to be at variance with his experience in the greater project area. The contractor should obtain the additional geotechnical information that is necessary to develop his workscope and cost estimates with sufficient precision. This includes, but is not limited to, information regarding excavation conditions, earth material usage, current depths to groundwater, etc. Because of the necessarily limited nature of the subsurface exploration performed for this study, the contractor should be allowed to evaluate the site using test pits or other means to obtain additional subsurface information to prepare his bid. If during construction, surface, soil, bedrock, or groundwater conditions appear to be at variance with those described herein, a geotechnical engineer should be retained at once, so that our conclusions for this site may be re-evaluated in a timely manner and dependent aspects of project design can be modified, as necessary. The materials present on-site are stable at their natural moisture content, but may change volume or lose bearing capacity or stability with changes in moisture content. Performance of the proposed structure and pavement will depend on implementation of the conclusions and information in this report and on proper maintenance after construction is completed. Because water is a significant cause of volume change in soils and rock, allowing moisture infiltration may result in movements, some of which will exceed estimates provided herein and should therefore be expected by Front Range Community College. ALL DEVELOPMENT CONTAINS INHERENT RISKS. It is important that ALL aspects of this report, as well as the estimated performance (and limitations with any such estimations) of proposed improvements are understood by Front Range Community College. Utilizing the geotechnical parameters and measures herein for planning, design, and/or construction constitutes understanding and acceptance of the Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 50 of 51 conclusions with regard to risk and other information provided herein, associated improvement performance, as well as the limitations inherent within such estimates. Ensuring correct interpretation of the contents of this report by others is not the responsibility of GROUND. If any information referred to herein is not well understood, it is imperative that Front Range Community College contact the author or a GROUND principal immediately. We will be available to meet to discuss the risks and remedial approaches presented in this report, as well as other potential approaches, upon request. This report was prepared in accordance with generally accepted soil and foundation engineering practice in the project area at the date of preparation. Current applicable codes may contain criteria regarding performance of structures and/or site improvements which may differ from those provided herein. Our office should be contacted regarding any apparent disparity. GROUND makes no warranties, either expressed or implied, as to the professional data, opinions or conclusions contained herein. Because of numerous considerations that are beyond GROUND’s control, the economic or technical performance of the project cannot be guaranteed in any respect. This document, together with the concepts and conclusions presented herein, as an instrument of service, is intended only for the specific purpose and client for which it was prepared. Re-use of, or improper reliance on this document without written authorization and adaption by GROUND Engineering Consultants, Inc., shall be without liability to GROUND Engineering Consultants, Inc. Front Range Community College Health Care Career Center Fort Collins, Colorado Job No. 18-0040 Ground Engineering Consultants, Inc. Page 51 of 51 GROUND appreciates the opportunity to complete this portion of the project and welcomes the opportunity to provide Front Range Community College with a proposal for construction observation and materials testing.

Roche [mailto:mroche@fcgov.com] Sent: Friday, October 05, 2018 1:53 PM To: Garland, Ann <Ann.Garland@frontrange.edu> Subject: RE: Front Range Community College, Landscape plans Hi Annie, 2 Sorry it has taken me a few weeks to get back to you! I have been meaning to send you a list of some guidelines to consider throughout the development review/SPAR process. Regarding what City Forestry will review on the plans, we typically like to see the following details shown: - City of Fort Collins General Landscape Notes (optional) and Tree Protection Notes (required) - attached - Existing tree locations surveyed and included on a site/landscape plan - Existing tree inventory table including species, size (caliper inches), condition, mitigation value (required number of mitigation trees*), and status of tree retention/removal/transplant. Trees are typically numbered on the plan and a corresponding number is provided in the inventory table. o *Since this is a SPAR, we will not require you to provide upsized mitigation trees. However, below I will provide the mitigation sizes in the case that you do wish to upsize replacement trees. If you would like my help, I am happy to meet on-site again to inventory the trees in more detail (size, condition, and recommended mitigation value).  Typical upsized mitigation tree sizes: • Canopy Shade Trees: 3.0” caliper B&B or equivalent • Evergreen Trees: 8’ height B&B or equivalent • Ornamental Trees: 2.5” caliper B&B or equivalent o Tree inventory table should include whether the tree is to remain and be protected, to be removed, or to be transplanted.  Trees to be removed are typically shown with a X over the symbol.  Transplanted trees are symbolized with a bolded, capital “T” next to the symbol. Our general transplanting note is also displayed on the landscape plans: Transplanting trees #__, SPECIES, shall follow the recommendations of a qualified tree transplanting contractor in terms of size, staking, mulching, and irrigation. If trees are transplanted back on-site, please provide the transplanting location on the site/landscape plans. - Proposed Plant List to include quantity, species (scientific and common name), size (caliper inches), method of transplant (B&B or equivalent), species diversity percentage o Typical planting sizes for new trees and shrubs:  Canopy Shade Trees: 2.0” caliper B&B or equivalent  Evergreen Trees: 6’ height B&B or equivalent  Ornamental Trees: 1.5” caliper B&B or equivalent  Shrubs: 5 gallon or adequate size consistent with design intent o Recommended Species list (attached). City Forestry will review trees in the plant list provided on the landscape plan. The City of Fort Collins recommended plant list is currently under review – contact Stephanie Blochowiak in Environmental Planning if you have questions on specific plants/varieties. o Species Diversity Percentage: • To prevent uniform insect or disease susceptibility and eventual uniform senescence on a development site or in the adjacent area or the district, species diversity is required and extensive monocultures are prohibited. The following minimum requirements shall apply to any development plan. Number of trees on site Maximum percentage of any one species 10-19 50% 20-39 33% 40-59 25% 3 60 or more 15% - Utility/Tree Separation Guidelines o Include utilities on the site/landscape plan (gas, electric, water, sanitary sewer, storm sewer, etc). Please consider placement of existing and proposed tree locations to meet the following separations:  10’ between trees and public water, sanitary, and storm sewer main lines, electric lines  6’ between trees and public water, sanitary, and storm sewer service lines  4’ between trees and gas lines - Street light/stop sign Separation Guidelines o Include locations of street lights (probably not proposed on this project) and stop signs on the site/landscape plan. Please consider placement of existing and proposed tree locations to meet the following separations:  Stop Signs: 20 feet from sign  Street Light: 40 feet for canopy shade trees and 15 feet for ornamental trees - Tree Protection Specifications o Tree Protection will be required around all City owned street trees between the curb and sidewalk along Shields Street and Horsetooth Road. Please follow the guidelines below. Tree protection is not required, but is encouraged, around all existing trees to retain on FRCC property.  (1) Within the drip line of any protected existing tree, there shall be no cut or fill over a four-inch depth unless a qualified arborist or forester has evaluated and approved the disturbance.  (2) All protected existing trees shall be pruned to the City of Fort Collins Forestry standards.  (3) Prior to and during construction, barriers shall be erected around all protected existing trees with such barriers to be of orange fencing a minimum of four (4) feet in height, secured with metal T-posts, no closer than six (6) feet from the trunk or one-half (½) of the drip line, whichever is greater. There shall be no storage or movement of equipment, material, debris or fill within the fenced tree protection zone.  (4) During the construction stage of development, the applicant shall prevent the cleaning of equipment or material or the storage and disposal of waste material such as paints, oils, solvents, asphalt, concrete, motor oil or any other material harmful to the life of a tree within the drip line of any protected tree or group of trees.  (5) No damaging attachment, wires, signs or permits may be fastened to any protected tree.  (6) Large property areas containing protected trees and separated from construction or land clearing areas, road rights-of-way and utility easements may be "ribboned off," rather than erecting protective fencing around each tree as required in subsection (G)(3) above. This may be accomplished by placing metal t-post stakes a maximum of fifty (50) feet apart and tying ribbon or rope from stake-to-stake along the outside perimeters of such areas being cleared.  (7) The installation of utilities, irrigation lines or any underground fixture requiring excavation deeper than six (6) inches shall be accomplished by boring under the root system of protected existing trees at a minimum depth of twenty-four (24) inches. The auger distance is established from the face of the tree (outer bark) and is scaled from tree diameter at breast height as described in the chart below. I am more than happy to provide additional information throughout the SPAR process. Please let me know if you have any questions! Have a great weekend!

City of Fort Collins Plant List April 2011 April 2011 2 City of Fort Collins Plant List City of Fort Collins Plant List This Plant List was developed to meet the provisions of the Land Use Code Section 3.2.1 regarding Landscape Plans that are submitted as part of the development review process. Landscape Plans are required for commercial, multifamily and common areas of subdivisions, but do not apply to single-family residences. The Land Use Code says that plant material for Landscape Plans must be selected from the City of Fort Collins Plant List. Additional plants may be added to the list upon a determination that the plants are appropriate for inclusion. In addition, hydrozones must be shown on the plan. Hydrozones are areas defined by a grouping of plants requiring a similar amount of water to sustain health. The four hydrozones based on supplemental irrigation needed: High Hydrozone (H): 18 gallons/s.f./season Moderate Hydrozone (M): 10 gallons/s.f./season Low Hydrozone (L): 3 gallons/s.f./season Very Low Hydrozone (VL): 0 gallons/s.f./season More Information about the Plants Books Armitage's Native Plants for North American Gardens by Allan Armitage Durable Plants for the Garden: A Plant Select Guide by Plant Select Manual of Herbaceous Ornamental Plants by Steven Still Manual of Woody Landscape Plants by Michael Dirr Waterwise Landscaping with Trees, Shrubs and Vines by Jim Knopf Western Garden Book by Kathleen Norris Brenzel Xeriscape Plant Guide by Denver Water Websites Bath Garden Center and Nursery: www.bathgardencenter.com City of Fort Collins Native Plant List: www.fcgov.com/naturalareas/native-plants.php Colorado State University Extension: www.ext.colostate.edu Fort Collins Nursery: www.fortcollinsnursery.com Fossil Creek Nursery: www.fossilcreeknursery.com Gulley Greenhouse: www.gulleygreenhouse.com Monrovia Nursery: www.monrovia.com Turfgrass Selection in Colorado: http://csuturf.colostate.edu Sources Used Fort Collins Wholesale Nursery Descriptive Guide - 4th Edition Little Valley Wholesale Nursery - 2009 catalog Waterwise Landscaping Best Management Practices Manual CSU Extension Fact Sheets: #7.229 Xeriscaping: Trees and Shrubs #7.230 Xeriscaping: Ground Cover Plants #7.231 Xeriscaping: Garden Flowers #7.232 Ornamental Grasses #7.405 Herbaceous Perennials #7.418 Small Deciduous Trees #7.419 Large Deciduous Trees #7.421 Native Trees for Colorado Landscapes #7.422 Native Shrubs for Colorado Landscapes April 2011 3 City of Fort Collins Plant List Street Trees Trees selected for planting as public street trees should be from the list below or approved by the City Forester.

DIVISION 3.2 SITE PLANNING AND DESIGN STANDARDS Sections: 3.2.1 Landscaping and Tree Protection 3.2.2 Access, Circulation and Parking 3.2.3 Solar Access, Orientation, Shading 3.2.4 Site Lighting 3.2.5 Trash and Recycling Enclosures 3.2.1 Landscaping and Tree Protection (A) Applicability. This Section shall apply to all development (except for development on existing lots for single-family detached dwellings) within the designated "limits of development" ("LOD") and natural area buffer zones established according to Section 3.4.1 (Natural Habitats and Features). (B) Purpose. The intent of this Section is to require preparation of landscape and tree protection plans that ensure significant canopy shading to reduce glare and heat build-up, contribute to visual quality and continuity within and between developments, provide screening and mitigation of potential conflicts between activity areas and site elements, enhance outdoor spaces, reduce erosion and stormwater runoff, encourage water conservation and mitigate air pollution. (C) General Standard. All developments shall submit a landscape and tree protection plan, and, if receiving water service from the City, an irrigation plan, that: (1) reinforces and extends any existing patterns of outdoor spaces and vegetation where practicable, (2) supports functional purposes such as spatial definition, visual screening, creation of privacy, management of microclimate or drainage, (3) enhances the appearance of the development and neighborhood, (4) protects significant trees, natural systems and habitat, (5) enhances the pedestrian environment, (6) identifies all landscape areas, (7) identifies all landscaping elements within each landscape area, and (8) meets or exceeds the standards of this Section. (D) Tree Planting Standards. All developments shall establish groves and belts of trees along all city streets, in and around parking lots, and in all landscape areas that are located within fifty (50) feet of any building or structure in order to establish at least a partial urban tree canopy. The groves and belts may also be combined or interspersed with other landscape areas in remaining portions of the development to accommodate views and functions such as active recreation and storm drainage. (1) Minimum Plantings/Description. These tree standards require at least a minimum tree canopy but are not intended to limit additional tree plantings in any remaining portions of the development. Groves and belts of trees shall be required as follows: (a) parking lot landscaping in accordance with the parking lot landscaping standards as set forth in this Section and in Section 3.2.2. Access, Circulation and Parking; (b) street tree planting in accordance with the Larimer County Urban Area Street Standards or other street tree planting as defined in subsection (2)(b) or (c) below; (c) "full tree stocking" shall be required in all landscape areas within fifty (50) feet of any building or structure as further described below. Landscape areas shall be provided in adequate numbers, locations and dimensions to allow full tree stocking to occur along all high use or high visibility sides of any building or structure. Such landscape areas shall extend at least seven (7) feet from any building or structure wall and contain at least fifty-five (55) square feet of nonpaved ground area, except that any planting cutouts in walkways shall contain at least sixteen (16) square feet. Planting cutouts, planters or other landscape areas for tree planting shall be provided within any walkway that is twelve (12) feet or greater in width adjoining a vehicle use area that is not covered with an overhead fixture or canopy that would prevent growth and maturity. Full tree stocking shall mean formal or informal groupings of trees planted according to the following spacing dimensions: Tree Type Minimum/Maximum Spacing Canopy shade Trees 30'-40' Coniferous evergreens 20'-30' Ornamental trees 20'-30' Exact locations and spacings may be adjusted at the option of the applicant to support patterns of use, views and circulation as long as the minimum tree planting requirement is met. Canopy shade trees shall constitute at least fifty (50) percent of all tree plantings. Trees required in subparagraphs (a) or (b) above may be used to contribute to this standard. (2) Street Trees. Planting of street trees shall occur in the adjoining street right-of-way in connection with the development by one (1) or more of the methods described in subparagraphs (a) through (c) below: (a) Wherever the sidewalk is separated from the street by a parkway, canopy shade trees shall be planted at thirty-foot to forty- foot spacing (averaged along the entire front and sides of the block face) in the center of all such parkway areas. If two (2) or more consecutive residential lots along a street each measure between forty (40) and sixty (60) feet in street frontage width, one (1) tree per lot may be substituted for the thirty-foot to forty-foot spacing requirement. Such street trees shall be placed at least eight (8) feet away from the edges of driveways and alleys, and forty (40) feet away from any streetlight and to the extent reasonably feasible, be positioned at evenly spaced intervals. (b) Wherever the sidewalk is attached to the street in a manner that fails to comply with the Larimer County Urban Area Street Standards, canopy shade trees shall be established in an area ranging from three (3) to seven (7) feet behind the sidewalk at the spacing intervals as required in subsection (a) above. Wherever the sidewalk is attached to the street and is ten (10) feet or more in width, or extends from the curb to the property line, canopy shade trees shall be established in planting cutout areas of at least sixteen (16) square feet at thirty-foot to forty-foot spacing. (c) Ornamental trees shall be planted in substitution for the canopy shade trees required in subsection (D)(2)(a) and (b) above where overhead lines and fixtures prevent normal growth and maturity. Ornamental trees shall be placed at least fifteen (15) feet away from any streetlight. (3) Minimum Species Diversity. To prevent uniform insect or disease susceptibility and eventual uniform senescence on a development site or in the adjacent area or the district, species diversity is required and extensive monocultures are prohibited. The following minimum requirements shall apply to any development plan. Number of trees on site Maximum percentage of any one species 10-19 50% 20-39 33% 40-59 25% 60 or more 15% (4) Tree Species and Minimum Sizes. The Director shall provide a recommended list of trees which shall be acceptable to satisfy the requirements for landscape plans, including approved canopy shade trees that may be used as street trees. The following minimum sizes shall be required (except as provided in subparagraph (5) below): Type Minimum Size Canopy Shade Tree 2.0" caliper balled and burlapped or equivalent Evergreen Tree 6.0' height balled and burlapped or equivalent Ornamental Tree 1.5" caliper balled and burlapped or equivalent Shrubs 5 gallon or adequate size consistent with design intent Canopy Shade Tree as a street tree on a Residential Local Street Only 1.25" caliper container or equivalent Any tree plantings that are in addition to those that are made as part of the approved landscape plan are exempt from the foregoing size requirements. (5) Reduced Minimum Sizes for Affordable Housing Projects. In any affordable housing project, the following minimum sizes shall be required: Type Minimum Size Canopy Shade Tree 1.0" caliper container or equivalent Evergreen Tree 4.0' height container or equivalent Ornamental Tree 1.0" caliper container or equivalent Shrubs 1 gallon Canopy Shade Tree as a street tree on a Local or Collector Street only 1.25" caliper container or equivalent (E) Landscape Standards. All development applications shall include landscape plans that meet the following minimum standards: (1) Buffering Between Incompatible Uses and Activities. In situations where the Director determines that the arrangement of uses or design of buildings does not adequately mitigate conflicts reasonably anticipated to exist between dissimilar uses, site elements or building designs, one (1) or more of the following landscape buffering techniques shall be used to mitigate the conflicts. (a) Separation and screening with plant material: planting dense stands of evergreen trees, canopy shade trees, ornamental trees or shrubs; (b) Integration with plantings: incorporating trees, vines, planters or other plantings into the architectural theme of buildings and their outdoor spaces to subdue differences in architecture and bulk and avoid harsh edges; (c) Establishing privacy: establishing vertical landscape elements to screen views into or between windows and defined outdoor spaces where privacy is important, such as where larger buildings are proposed next to side or rear yards of smaller buildings; (d) Visual integration of fences or walls: providing plant material in conjunction with a screen panel, arbor, garden wall, privacy fence or security fence to avoid the visual effect created by unattractive screening or security fences; (e) Landform shaping: utilizing berming or other grade changes to alter views, subdue sound, change the sense of proximity and channel pedestrian movement. (2) Landscape Area Treatment. Landscape areas shall include all areas on the site that are not covered by buildings, structures, paving or impervious surface. Landscape areas shall consist only of landscaping. The selection and location of turf, ground cover (including shrubs, grasses, perennials, flowerbeds and slope retention), and pedestrian paving and other landscaping elements shall be used to prevent erosion and meet the functional and visual purposes such as defining spaces, accommodating and directing circulation patterns, managing visibility, attracting attention to building entrances and other focal points, and visually integrating buildings with the landscape area and with each other. (a) Turf grass. High-use areas shall be planted with irrigated turf grass. Nonirrigated shortgrass prairie grasses or other adapted grasses that have been certified as Xeriscape landscaping may be established in remote, low-use, low visibility areas. (b) Planting beds. Shrub and ground cover planting beds shall be separated from turf grass with edging and shall have open surface areas covered with mulch. (c) Slopes. Retaining walls, slope revetment or other acceptable devices integrated with plantings shall be used to stabilize slopes that are steeper than 3:1. If soil tests performed on the subject soils indicate steeper slopes are stable without the above required protection, then the maximum slope allowed without the above required protection may be increased to the maximum stated in the soils report or 2:1, whichever is less steep. (d) Foundation Plantings. Exposed sections of building walls that are in high-use or high-visibility areas of the building exterior shall have planting beds at least five (5) feet wide placed directly along at least fifty (50) percent of such walls. (e) Parkways. All adjoining street parkways shall be landscaped in connection with the development in accordance with the Larimer County Urban Area Street Standards. (f) Agricultural Use. If outdoor space is maintained in active agricultural use, the landscape surfaces and ground cover standards above shall not apply. (3) Water Conservation. To the extent reasonably feasible, all landscape plans shall be designed to incorporate water conservation materials and techniques in order to comply with each of the Xeriscape landscaping principles listed below. Xeriscape landscaping principles do not include or allow artificial turf or plants, mulched (including gravel) beds or areas without landscape plant material, paving of areas not required for walkways, plazas or parking lots, bare ground, weed covered or infested surfaces or any landscaping that does not comply with the standards of this section. (a) Xeriscape landscaping principles are as follows: 1. Design. Identify zones of different water requirements and group plants together that have similar water needs; 2. Appropriate Use of Turf. Limit high-irrigation turf and plantings to appropriate high-use areas with high visibility and functional needs; 3. Low-Water-Using Plants. Choose low-water-demanding plants and turf where practicable; 4. Irrigation. Design, operate and maintain an efficient irrigation system; 5. Soil Preparation. Incorporate soil amendments before planting; 6. Mulch. Add mulch to planting beds to a minimum depth of three (3) inches; 7. Maintenance. Provide regular and attentive maintenance. (b) Landscape plans submitted shall include: 1. Accurate and clear identification of all applicable hydrozones using the following categories: High Hydrozone: 18 gallons/s.f./season Moderate Hydrozone: 10 gallons/s.f./season Low Hydrozone: 3 gallons/s.f./season Very Low Hydrozone: 0 gallons/s.f./season 2. A water budget chart that shows the total annual water use, which shall not exceed fifteen (15) gallons/square foot over the site, including all hydrozones used on the landscape plan. (4) Parking Lot Perimeter Landscaping. Parking lot perimeter landscaping (in the minimum setback areas required by Section 3.2.2(J) (Access, Circulation and Parking) shall meet the following minimum standards: (a) Trees shall be provided at a ratio of one (1) tree per twenty-five (25) lineal feet along a public street and one (1) tree per forty (40) lineal feet along a side lot line parking setback area. Trees may be spaced irregularly in informal groupings or be uniformly spaced, as consistent with larger overall planting patterns and organization. Perimeter landscaping along a street may be located in and should be integrated with the streetscape in the street right-of-way. (b) Screening. Parking lots with six (6) or more spaces shall be screened from abutting uses and from the street. Screening from residential uses shall consist of a fence or wall six (6) feet in height in combination with plant material and of sufficient opacity to block at least seventy-five (75) percent of light from vehicle headlights. Screening from the street and all nonresidential uses shall consist of a wall, fence, planter, earthen berm, plant material or a combination of such elements, each of which shall have a minimum height of thirty (30) inches. Such screening shall extend a minimum of seventy (70) percent of the length of the street frontage of the parking lot and also seventy (70) percent of the length of any boundary of the parking lot that abuts any nonresidential use. Openings in the required screening shall be permitted for such features as access ways or drainage ways. Where screening from the street is required, plans submitted for review shall include a graphic depiction of the parking lot screening as seen from the street. Plant material used for the required screening shall achieve required opacity in its winter seasonal condition within three (3) years of construction of the vehicular use area to be screened. (5) Parking Lot Interior Landscaping. As required in Section 3.2.2(M)(1) Access, Circulation and Parking, six (6) percent of the interior space of all parking lots with less than one hundred (100) spaces, and ten (10) percent of the interior space of all parking lots with one hundred (100) spaces or more shall be landscape areas. (See Figure 1). All parking lot islands, connecting walkways through parking lots and driveways through or to parking lots shall be landscaped according to the following standards: (a) Visibility. To avoid landscape material blocking driver sight distance at driveway-street intersections, no plant material greater than twenty-four (24) inches in height shall be located within fifteen (15) feet of a curbcut. (b) Maximized Area of Shading. Landscaped islands shall be evenly distributed to the maximum extent feasible. At a minimum, trees shall be planted at a ratio of at least one (1) canopy shade tree per one hundred fifty (150) square feet of internal landscaped area with a landscaped surface of turf, ground cover perennials or mulched shrub plantings. (c) Landscaped Islands. In addition to any pedestrian refuge areas, each landscaped island shall include one (1) or more canopy shade trees, be of length greater than eight (8) feet in its smallest dimension, include at least eighty (80) square feet of ground area per tree to allow for root aeration, and have raised concrete curbs. Figure 1 Interior Landscaping for Vehicular Use Areas (d) Walkways and Driveways.

Detailed specifications concerning parking lot surfacing material and parking lot drainage detention are available from the City Engineer. (6) Screening. Landscape and building elements shall be used to screen areas of low visual interest or visually intrusive site elements (such as trash collection, open storage, service areas, loading docks and blank walls) from off-site view. Such screening shall be established on all sides of such elements except where an opening is required for access. If access is possible only on a side that is visible from a public street, a removable or operable screen shall be required. The screen shall be designed and established so that the area or element being screened is no more than twenty (20) percent visible through the screen. (a) Screening Materials. Required screening shall be provided in the form of new or existing plantings, walls, fences, screen panels, topographic changes, buildings, horizontal separation or a combination of these techniques. (7) Landscaping of Vehicle Display Lots. Vehicle display lots for vehicle sales and leasing (as those terms are defined in Article 5) that abut an arterial or collector street shall feature landscaped islands along the street at an interval not to exceed every fifteen (15) vehicles or one hundred thirty-five (135) feet, whichever is less. Each landscaped island shall comply with the requirements of Section 3.2.1(E)(5)(c). (F) Tree Protection and Replacement. Existing significant trees within the LOD and within natural area buffer zones shall be preserved to the extent reasonably feasible and may help satisfy the landscaping requirements of this Section as set forth above. Such trees shall be considered "protected" trees within the meaning of this Section, subject to the exceptions contained in subsection (2) below. Streets, buildings and lot layouts shall be designed to minimize the disturbance to significant existing trees. All required landscape plans shall accurately identify the locations, species, size and condition of all significant trees, each labeled showing the applicant’s intent to either remove, transplant or protect. Where it is not feasible to protect and retain significant existing tree(s) or to transplant them to another on-site location, the applicant shall replace such tree(s) according to the following schedule and requirements. Replacement trees shall be used to satisfy the tree planting standards of this Section. Replacement trees shall be planted either on the development site or in the closest available and suitable planting site. The closest available and suitable planting site shall be selected within one-half (½) mile (2,640 feet) of the development site, subject to the following exceptions. If suitable planting sites for all of the mitigation trees are not available within one-half (½) mile (2,640 feet) of the development, then the planting site shall be selected within one (1) mile (5,280 feet) of the development site. If suitable planting sites are not available for all of the mitigation trees within one (1) mile (5,280 feet) of the development site, then the City Forester shall determine the most suitable planting location within the City's boundaries as close to the development site as feasible. (1) A significant tree that is removed shall be replaced with not less than one (1) or more than six (6) replacement trees sufficient to mitigate the loss of value of the removed significant tree. Notwithstanding the foregoing, significant Siberian elm and Russian olive trees located in a natural habitat buffer found to contain ecological value, as provided in paragraph 3.4.1(D)(1) of this Code, shall be mitigated in accordance with subparagraph 3.4.1(E)(2)(b) of this Code. The applicant shall select either the City Forester or a qualified landscape appraiser to determine such loss based upon an appraisal, including, but not limited to, shade, canopy, aesthetic, environmental and ecological value of the tree to be removed and by using the species and location criteria in the most recent published appraisal guide by the Council of Tree and Landscape Appraisers. Replacement trees shall meet the following minimum size requirements: (a) Canopy Shade Trees: 3.0" caliper balled and burlap or equivalent. (b) Ornamental Trees: 2.5" caliper balled and burlap or equivalent. (c) Evergreen Trees: 8' height balled and burlap or equivalent. (2) Trees that meet one (1) or more of the following removal criteria shall be exempt from the requirements of this subsection: (a) dead, dying or naturally fallen trees, or trees found to be a threat to public health, safety or welfare; (b) trees that are determined by the City to substantially obstruct clear visibility at driveways and intersections; (c) Siberian elm less than eleven (11) inches DBH and Russian olive less than eight (8) inches DBH; (d) Russian olive and Siberian elm of wild or volunteer origin, such as those that have sprouted from seed along fence lines, near structures or in other unsuitable locations; (e) Russian olive and Siberian elm determined by the City Forester to be in poor condition. (3) All existing street trees that are located on city rights-of-way abutting the development shall be accurately identified by species, size, location and condition on required landscape plans, and shall be preserved and protected in accordance with the standards of subsection (G). (G) Tree Protection Specifications. The following tree protection specifications should be followed to the maximum extent feasible for all projects with protected existing trees. (1) Within the drip line of any protected existing tree, there shall be no cut or fill over a four-inch depth unless a qualified arborist or forester has evaluated and approved the disturbance. (2) All protected existing trees shall be pruned to the City of Fort Collins Forestry standards. (3) Prior to and during construction, barriers shall be erected around all protected existing trees with such barriers to be of orange fencing a minimum of four (4) feet in height, secured with metal T-posts, no closer than six (6) feet from the trunk or one-half (½) of the drip line, whichever is greater. There shall be no storage or movement of equipment, material, debris or fill within the fenced tree protection zone. (4) During the construction stage of development, the applicant shall prevent the cleaning of equipment or material or the storage and disposal of waste material such as paints, oils, solvents, asphalt, concrete, motor oil or any other material harmful to the life of a tree within the drip line of any protected tree or group of trees. (5) No damaging attachment, wires, signs or permits may be fastened to any protected tree. (6) Large property areas containing protected trees and separated from construction or land clearing areas, road rights-of-way and utility easements may be "ribboned off," rather than erecting protective fencing around each tree as required in subsection (G)(3) above. This may be accomplished by placing metal t-post stakes a maximum of fifty (50) feet apart and tying ribbon or rope from stake-to-stake along the outside perimeters of such areas being cleared. (7) The installation of utilities, irrigation lines or any underground fixture requiring excavation deeper than six (6) inches shall be accomplished by boring under the root system of protected existing trees at a minimum depth of twenty-four (24) inches. The auger distance is established from the face of the tree (outer bark) and is scaled from tree diameter at breast height as described in the chart below. Tree Diameter at Breast Height (inches) Auger Distance From Face of Tree (feet) 0-2 1 3-4 2 5-9 5 10-14 10 15-19 12 Over 19 15 (H) Placement and Interrelationship of Required Landscape Plan Elements. In approving the required landscape plan, the decision maker shall have the authority to determine the optimum placement and interrelationship of required landscape plan elements such as trees, vegetation, turf, irrigation, screening, buffering and fencing, based on the following criteria: (1) protecting existing trees, natural areas and features; (2) enhancing visual continuity within and between neighborhoods; (3) providing tree canopy cover; (4) creating visual interest year round; (5) complementing the architecture of a development; (6) providing screening of areas of low visual interest or visually intrusive site elements; (7) establishing an urban context within mixed-use developments; (8) providing privacy to residents and users; (9) conserving water; (10) avoiding reliance on excessive maintenance; (11) promoting compatibility and buffering between and among dissimilar land uses; (12) establishing spatial definition. (I) Landscape Materials, Maintenance and Replacement. (1) Topsoil. To the maximum extent feasible, topsoil that is removed during construction activity shall be conserved for later use on areas requiring revegetation and landscaping. Organic soil amendments shall also be incorporated in accordance with the requirements of Section 3.8.21. (2) Plant Materials. Plant materials shall be selected from a list of native plants and other plants determined to be appropriate for and well adapted to local environmental conditions, as such list is established and updated from time to time by the Director and entitled the City of Fort Collins Plant List. Additional plants may be added to the Plant List upon a determination by the Director that such plants are appropriate for inclusion consistent with the above standard. (3) Plant Quality. All plants shall be A-Grade or No. 1 Grade, free of any defects, of normal health, height, leaf density and spread appropriate to the species as defined by American Association of Nurserymen standards. (4) Installation. All landscaping shall be installed according to sound horticultural practices in a manner designed to encourage quick establishment and healthy growth. All landscaping in each phase shall either be installed or the installation shall be secured with a letter of credit, escrow or performance bond for one hundred twenty-five (125) percent of the value of the landscaping prior to the issuance of a certificate of occupancy for any building in such phase. (5) Maintenance. Trees and vegetation, irrigation systems, fences, walls and other landscape elements shall be considered as elements of the project in the same manner as parking, building materials and other site details. The applicant, landowner or successors in interest shall be jointly and severally responsible for the regular maintenance of all landscaping elements in good condition. All landscaping shall be maintained free from disease, pests, weeds and litter, and all landscape structures such as fences and walls shall be repaired and replaced periodically to maintain a structurally sound condition. (6) Replacement. Any landscape element that dies, or is otherwise removed, shall be promptly replaced based on the requirements of this Section. (7) Mitigation. Healthy, mature trees that are removed by the applicant or by anyone acting on behalf of or with the approval of the applicant shall be replaced with not less than one (1) or more than six (6) replacement trees sufficient to mitigate the loss of value of the removed tree. The applicant shall select either the City Forester or a qualified landscape appraiser to determine such loss based upon an appraisal of the removed tree, using the most recent published methods established by the Council of Tree and Landscape Appraisers. Larger than minimum sizes (as set forth in subsection (D)(4) above) shall be required for such replacement trees. (J) Irrigation. (1) Provision shall be made for permanent, automatic irrigation of all plant material, with the following exceptions: (a) very low-water-use plantings that do not require any supplemental irrigation beyond establishment. (b) trees and other plants used to landscape a residential local street parkway abutting lots for single-family detached dwellings. (2) For any development provided water by the City, an irrigation plan shall be submitted to and approved by the Utilities Executive Director prior to the issuance of the building permit, or if no building permit is required, then prior to commencement of construction. As determined by the Director, minor redevelopment or change of use projects may not be required to submit an irrigation plan; in such cases, a written statement shall be submitted describing the type of irrigation system proposed. The irrigation plan shall incorporate the City of Fort Collins Irrigation System Standards for Water Conservation set forth below. In addition, the irrigation system must be inspected for compliance with the approved irrigation plan before the issuance of a Certificate of Occupancy. (3) The City of Fort Collins Irrigation System Standards for Water Conservation are as follows: (a) Irrigation Methods and Layout. 1. The irrigation system shall be designed according to the hydrozones shown on the landscape plan. 2. Each zone shall irrigate a landscape with similar site, soil conditions and plant material having similar water needs. To the extent reasonably feasible, areas with significantly different solar exposures shall be zoned separately. 3. Turf and non-turf areas shall be irrigated on separate zones. 4. On steep grades, an irrigation method with a lower precipitation rate shall be used in order to minimize runoff, and, to the extent reasonably feasible, these areas shall be zoned separately. 5. Drip, micro-sprays, sprayheads and rotors shall not be combined on the same zone. 6. The irrigation method shall be selected to correlate with the plant density. Drip irrigation or bubblers shall be used for sparsely planted trees and shrubs, and rotors, sprayheads and multi-jet rotary nozzles shall be used for turfgrass. (b) Equipment Selection. 1. In order to reduce leakage of water from the irrigation system, a master shut-off valve shall be installed downstream of the backflow device to shut off water to the system when not operating. 2. For irrigation systems that are on a combined-use tap, with a water meter installed upstream to measure total water use, the installation of an irrigation-only submeter should be considered. The purpose of the submeter would be to enable the owner and landscape maintenance contractor to monitor water use for irrigation. The submeter would not be used for billing purposes. The cost of installation and maintenance of a submeter, if used, would be borne by the owner of the property and not by the City. All such submeters would have to be installed in accordance with the specifications established by the City. 3. Irrigation controllers shall be "smart" controllers, using climate-based or soil moisture-based technology, selected from the Irrigation Association's current Smart Water Application Technologies (SWAT) tested products list or other similarly tested product list. Controllers shall be installed and programmed according to manufacturer's specifications. a. A data input chart for the Smart Controller, including the precipitation rate from the audit, shall be posted at each irrigation controller. b. Within six (6) weeks of the installation of new landscaping, the irrigation system Smart Controllers shall be reset to the normal seasonal watering schedule. 4. A rain sensor shall be installed on each irrigation controller and installed according to the manufacturer's specifications. 5. Sprinklers and nozzles shall meet the following requirements: a. The type of sprinkler and associated nozzles shall be selected to correlate with the size and geometry of the zone being irrigated. b. Sprinklers shall be spaced no closer than seventy- five (75) percent of the maximum radius of throw for the given sprinkler and nozzle. Maximum spacing shall be head-to-head coverage. c. Coverage arcs and radius of throw for turf areas shall be selected and adjusted to water only turf areas and minimize overspray onto vegetated areas, hard surfaces, buildings, fences or other non- landscaped surfaces. d. Sprinklers, bubblers or emitters on a zone shall be of the same manufacturer. e. Sprayheads in turf areas shall have a minimum three-and-one-half-inch pop-up riser height. f. Sprayheads on a zone shall have matched precipitation nozzles. g. Nozzles for rotors shall be selected to achieve an approximate uniform precipitation rate throughout the zone. h. All sprayheads and rotors shall be equipped with check valves. Sprayheads shall also have pressure- regulating stems. 6. Pressure-compensating emitters shall be used for drip irrigation. For sloped areas, a check valve shall be installed, and the drip line shall be parallel to the slope. 7. Remote control valves shall have flow control. 8. A backflow prevention assembly shall be installed in accordance with local codes. All backflow assemblies shall be equipped with adequately sized winterization ports downstream of the backflow assembly. 9. Properties with single or combined point of connection flows of two hundred (200) gpm or greater shall have a control system capable of providing real-time flow monitoring and the ability to shut down the system in the event of a high-flow condition. (c) Sleeving. 1. Separate sleeves shall be installed beneath paved areas to route each run of irrigation pipe or wiring bundle. The diameter of sleeving shall be twice that of the pipe or wiring bundle. 2. The sleeving material beneath sidewalks, drives and streets shall be PVC Class 200 pipe with solvent welded joints. (d) Water Pressure. 1. The irrigation system designer shall verify the existing available water pressure. 2. The irrigation system shall be designed such that the point-of-connection design pressure, minus the possible system pressure losses, is greater than or equal to the design sprinkler operating pressure. 3. All pop-up spray sprinkler bodies equipped with spray nozzles shall operate at no less than twenty (20) psi and no more than thirty (30) psi. 4. All rotary sprinklers and multi-stream rotary nozzles on pop-up spray bodies shall operate at the manufacturer's specified optimum performance pressure. 5. If the operating pressure exceeds the manufacturer's specified maximum operating pressure for any sprinkler body, pressure shall be regulated at the zone valve or sprinkler heads. 6. Booster pumps shall be installed on systems where supply pressure does not meet the manufacturer's minimum recommended operating pressure for efficient water distribution. (e) Sprinkler Performance Audit. 1. A sprinkler performance audit shall be performed by a landscape irrigation auditor who is independent of the installation contractor, and who is certified by the Irrigation Association (a nonprofit industry organization dedicated to promoting efficient irrigation). Sprinkler systems that are designed and installed without turf areas are exempt from this requirement. 2. The audit shall include measurement of distribution uniformity. Minimum acceptable distribution uniformities shall be sixty (60) percent for sprayhead zones and seventy (70) percent for rotor zones. Sprinkler heads equipped with multi-stream rotary nozzles are considered rotors. 3. The audit shall measure the operating pressure for one (1) sprinkler on each zone to determine whether the zone meets the above pressure requirements. 4. A copy of the sprinkler performance audit shall be submitted to and approved by the City before issuance of a certificate of occupancy. (K) Utilities and Traffic. Landscape, utility and traffic plans shall be coordinated. The following list sets forth minimum dimension requirements for the most common tree/utility and traffic control device separations. Exceptions to these requirements may occur where utilities or traffic control devices are not located in their standard designated locations, as approved by the Director. Tree/utility and traffic control device separations shall not be used as a means of avoiding the planting of required street trees. (1) Forty (40) feet between shade trees and streetlights. Fifteen (15) feet between ornamental trees and streetlights. (See Figure 2.) Figure 2 Tree/Streetlight Separations (2) Twenty (20) feet between shade and/or ornamental trees and traffic control signs and devices. (3) Ten (10) feet between trees and water or sewer mains. (4) Six (6) feet between trees and water or sewer service lines. (5) Four (4) feet between trees and gas lines. (6) Street trees on local streets planted within the eight-foot-wide utility easement may conflict with utilities. Additional conduit may be required to protect underground electric lines. (L) Visual Clearance or Sight Distance Triangle. Except as provided in Subparagraphs (1) and (2) below, a visual clearance triangle, free of any structures or landscape elements over twenty-four (24) inches in height, shall be maintained at street intersections and driveways in conformance with the standards contained in the Larimer County Urban Area Street Standards. (1) Fences shall not exceed forty-two (42) inches in height and shall be of an open design. (2) Deciduous trees may be permitted to encroach into the clearance triangle provided that the lowest branch of any such tree shall be at least six (6) feet from grade. (M) Revegetation. When the development causes any disturbance within any natural area buffer zone, revegetation shall occur as required in paragraph 3.4.1(E)(2) (Development Activities Within the Buffer Zone) and subsection 3.2.1(F) (Tree Protection and Replacement). (N) Alternative Compliance. Upon request by an applicant, the decision maker may approve an alternative landscape and tree protection plan that may be substituted in whole or in part for a landscape plan meeting the standards of this Section. (1) Procedure. Alternative landscape plans shall be prepared and submitted in accordance with submittal requirements for landscape plans. Each such plan shall clearly identify and discuss the modifications and alternatives proposed and the ways in which the plan will better accomplish the purposes of this Section than would a plan which complies with the standards of this Section. (2) Review Criteria. To approve an alternative plan, the decision maker must first find that the proposed alternative plan accomplishes the purposes of this Section equally well or better than would a plan which complies with the standards of this Section. In reviewing the proposed alternative plan for purposes of determining whether it accomplishes the purposes of this Section as required above, the decision maker shall take into account whether the alternative preserves and incorporates existing vegetation in excess of minimum standards, protects natural areas and features, maximizes tree canopy cover, enhances neighborhood continuity and connectivity, fosters nonvehicular access, or demonstrates innovative design and use of plant materials and other landscape elements.
