GENERAL INFORMATION This document was developed for use in situations involving changes in the Work which, if not processed expeditiously, might delay the Project. These changes are often initiated in the field and may affect the Contract Price or the Contract Times. This is not a Change Order, but only a directive to proceed with the Work that may be included in a subsequent Change Order. For supplemental instructions and minor changes not involving a change in the Contract Price or the Contract Times a Field Order should be used. B. COMPLETING THE WORK CHANGE DIRECTIVE FORM Engineer initiates the form, including a description of the items involved and attachments. Based on conversations between the Engineer/Owner and Contractor, Engineer completes the following: METHOD OF DETERMINING CHANGE, IF ANY, IN CONTRACT PRICE: Mark the method to be used in determining the final cost of Work involved and the estimated net effect on the Contract Price. If the change involves an increase in the Contract Price and the estimated amount is approached before the additional or changed Work is completed, another Work Change Directive must be issued to change the estimated price or Contractor may stop the changed Work when the estimated time is reached. If the Work Change Directive is not likely to change the Contract Price, the space for estimated increase (decrease) should be marked “Not Applicable”. Once Engineer has completed and signed the form, all copies should be sent to Owner for authorization because Engineer alone does not have authority to authorize changes in Price or Times. Once authorized by Owner, a copy should be sent by Engineer to Contractor. Price and Times may only be changed by Change Order signed by Owner and Contractor with Engineer’s recommendation. Article 10 of the General Conditions requires that a Change Order be initiated and processed to cover any undisputed sum or amount of time for Work actually performed pursuant to this Work Change Directive. Once the Work covered by this directive is completed or final cost and times are determined, Contractor should submit documentation for inclusion in a Change Order. IF THIS IS A DIRECTIVE TO PROCEED WITH A CHANGE THAT MAY AFFECT THE CONTRACT PRICE OR CONTRACT TIMES. A CHANGE ORDER, IF ANY, SHOULD BE CONSIDERED PROMPTLY. WORK CHANGE DIRECTIVE NO.

SUBSURFACE UTILITY ENGINEERING (SUE) IS A PROFESSIONAL PRACTICE DEFINED BY THE AMERICAN SOCIETY OF CIVIL ENGINEERS (ASCE). SURVWEST PERFORMS SUE INVESTIGATIONS IN CONFORMANCE WITH THE COLORADO SENATE BILL 18-167 AND THE CONSTRUCTION INSTITUTE (CI) / ASCE 38-02 (OR LATEST REVISION BY SAME OR DIFFERENT TITLE), “STANDARD GUIDELINE FOR THE COLLECTION AND DEPICTION OF EXISTING SUBSURFACE UTILITY DATA”. IDENTIFYING AND DOCUMENTING UNDERGROUND UTILITIES IS THE RESULT OF GATHERING EVIDENCE FROM VARIOUS SOURCES AND IS LIMITED TO THE ACCURACY OF THE GEOPHYSICAL TOOLS USED, SURVEYING CONTROL AND EQUIPMENT USED, FIELD METHODOLOGIES USED, AND WEATHER CONDITIONS ENCOUNTERED. THE EXACT LOCATIONS OF INDIVIDUAL SUBSURFACE UTILITY INFRASTRUCTURE SHOWN IN THESE PLANS ARE NOT CONFIRMED UNLESS THEY WERE VISUALLY EXPOSED AND SURVEYED, AND SUCH INFORMATION OBTAINED ONLY APPLIES TO THOSE SPECIFIC EXPOSED LOCATIONS OF THE SUBJECT UTILITY INFRASTRUCTURE. IF ANY UTILITIES CONFLICT WITH THE PROPOSED DESIGN BY OTHERS, SURVWEST RECOMMENDS THAT THE OWNER AND/OR DESIGN ENGINEER COMPLETE A QUALITY LEVAL A TEST HOLE AT EACH CONFLICT LOCATION PRIOR TO FINAL DESIGN AND CONSTRUCTION TO DETERMINE THE EXACT HORIZONTAL AND VERTICAL POSITION OF THE SUBJECT UTILITY INFRASTRUCTURE. 2. UTILITIES ARE DEPICTED IN THESE PLANS IN ACCORDANCE WITH THEIR ACHIEVED QUALITY LEVELS AS DEFINED IN THE CI/ASCE 38-02 (OR LATEST REVISION BY SAME OR DIFFERENT TITLE), “STANDARD GUIDELINE FOR THE COLLECTION AND DEPICTION OF EXISTING SUBSURFACE UTILITY DATA”. BASED ON TYPICAL TASKS LEADING TO UTILITY DEPICTION, ASCE DEFINES THE QUALITY LEVELS AS FOLLOWS. ·QUALITY LEVEL D (QL-D): “INFORMATION DERIVED FROM EXISTING RECORDS OR ORAL RECOLLECTION.” ·QUALITY LEVEL C (QL-C): “INFORMATION OBTAINED BY SURVEYING AND PLOTTING VISIBLE ABOVE-GROUND UTILITY FEATURES AND BY USING PROFESSIONAL JUDGEMENT IN CORRELATING THIS INFORMATION TO QUALITY LEVEL D INFORMATION.” ·QUALITY LEVEL B (QL-B): “INFORMATION OBTAINED THROUGH THE APPLICATION OF APPROPRIATE SURFACE GEOPHYSICAL METHODS TO DETERMINE THE EXISTENCE AND APPROXIMATE HORIZONTAL POSITION OF SUBSURFACE UTILITIES. QL-B DATA SHOULD BE REPRODUCIBLE BY SURFACE GEOPHYSICS AT ANY POINT OF THEIR DEPICTION. THIS INFORMATION IS SURVEYED TO APPLICABLE TOLERANCES DEFINED BY THE PROJECT AND REDUCED ONTO PLAN DOCUMENTS.” ·QUALITY LEVEL A (QL-A): “PRECISE HORIZONTAL AND VERTICAL LOCATION OF UTILITIES OBTAINED BY ACTUAL EXCAVATION (OR VERIFICATION OF PREVIOUSLY EXPOSED AND SURVEYED UTILITIES) AND SUBSEQUENT MEASUREMENT OF SUBSURFACE UTILITIES, USUALLY AT A SPECIFIC POINT. MINIMALLY INTRUSIVE EXCAVATION EQUIPMENT IS TYPICALLY USED TO MINIMIZE THE POTENTIAL FOR UTILITY DAMAGE. A PRECISE HORIZONTAL AND VERTICAL LOCATION, AS WELL AS OTHER UTILITY ATTRIBUTES, IS SHOWN ON PLAN DOCUMENTS. ACCURACY IS TYPICALLY SET TO 15-MM VERTICAL AND TO APPLICABLE HORIZONTAL SURVEY AND MAPPING ACCURACY AS DEFINED OR EXPECTED BY THE PROJECT OWNER.” 3. RELIANCE UPON THESE DATA FOR RISK MANAGEMENT PURPOSES DURING BIDDING DOES NOT RELIEVE THE PROJECT OWNER, ONWER'S ENGINEER, CONTRACTOR, OR UTILITY OWNER FROM FOLLOWING ALL APPLICABLE UTILITY DAMAGE PREVENTION STATUTES, POLICIES, AND/OR PROCEDURES DURING EXCAVATION. IT IS IMPORTANT THAT THE CONTRACTOR INVESTIGATES AND UNDERSTANDS THE SCOPE OF WORK BETWEEN THE PROJECT OWNER(S) AND THEIR ENGINEER REGARDING THE SCOPE AND LIMITS OF THE UTILITY INVESTIGATIONS LEADING TO THESE UTILITY DEPICTIONS. 4. THESE PLANS HAVE BEEN PREPARED FOR THE USE OF SURVWEST'S CLIENT AND MAY NOT BE USED, REPRODUCED OR RELIED UPON BY THIRD PARTIES EXCEPT BY THE EXPRESS WRITTEN CONSENT OF SURVWEST AND THEIR CLIENT, OR AS REQUIRED BY LAW. 5. THIS SUE INVESTIGATION DEPICTS UTILITIES FOR PLANNING AND DESIGN PURPOSES ONLY - NOT FOR CONSTRUCTION. SUE NOTES PERIOD OF DATA COLLECTION 1. SUE INVESTIGATION FIELD WORK WAS PERFORMED BETWEEN 03/28/2024 - 04/04/2024, 08/02/2024 - 08/05/2024, AND 9/06/2024. 2. SURVWEST WILL NOT BE HELD LIABLE FOR THE DEPICTION OF ANY CHANGES IN FIELD CONDITIONS RELATED TO THESE PLANS, INCLUDING UTILITIES AND APPURTENANCES THAT WERE INSTALLED, REMOVED, OR ADJUSTED AFTER THE FIELD WORK WAS COMPLETED. RECORDS RESEARCH & SITE RECONNAISSANCE 1. SURVWEST REQUESTED UTILITY INFORMATION SUCH AS FACILITY MAPS AND RECORD DRAWINGS FROM KNOWN UTILITY OWNERS (CO 811 MEMBERS) AND APPLICABLE CUSTODIANS OF UTILITY RECORDS. 2. SURVWEST SCANNED THE LIMITS OF INVESTIGATION FOR EVIDENCE OF ADDITIONAL UTILITIES NOT MADE KNOWN DURING RECORDS RESEARCH. 3. UTILITIES NOT DISCOVERED THROUGH RECORDS RESEARCH OR SITE INVESTIGATION SHALL BE REFERRED TO AS UNDOCUMENTED UTILITIES. SURVWEST IS NOT RESPONSIBLE FOR DEPICTING UNDOCUMENTED/UNKNOWN UTILITIES. 4. UTILITIES DOCUMENTED IN RECORDS, IF AVAILABLE TO SURVWEST, ARE DEPICTED AS QL-D UNLESS A HIGHER QUALITY LEVEL WAS ACHIEVED. 5. THE UTILITY COMPANIES PRESENTED IN TABLE 1 - UTILITY OWNER INFORMATION BELOW WERE EITHER CONTACTED DIRECTLY OR NOTIFIED OF THE PROJECT VIA THE CO 811 ENGINEERING TICKET SYSTEM. THIS INFORMATION IS CURRENT AS OF THE ORIGINAL ISSUE DATE OF THESE PLANS. THE SYSTEM GENERATED 811 TICKET NUMBER IS B407804752-00B (03/18/2024). TABLE 1 - UTILITY OWNER INFORMATION GEOPHYSICAL INVESTIGATION 1. SURVWEST PERFORMED THE GEOPHYSICAL SUE INVESTIGATION FOR THIS PROJECT IN ACCORDANCE WITH ITS STANDARD OF PRACTICE WHICH GENERALLY CONFORMS TO CI/ASCE 38-02 (OR LATEST REVISION BY SAME OR DIFFERENT TITLE) AND ALIGNS WITH GENERALLY ACCEPTABLE INDUSTRY STANDARDS. THIS INVOLVED THE TRACING OF DISTINCT, KNOWN, AND DETECTABLE UTILITY ALIGNMENTS WITHIN THE LIMITS OF INVESTIGATION. HOWEVER, THIS EFFORT IS NOT A TOTAL GEOPHYSICAL SWEEP OF THE LIMITS OF INVESTIGATION. 2. FOR UTILITIES WHERE A TRACER WIRE IS PRESENT IN A USUABLE CONDITION, THOSE UTILITIES HAVE BEEN DESIGNATED AND LABELED AS QL-B HEREIN UPON SUCCESSFUL DESIGNATION. HOWEVER, DUE TO THE UNKNOWN METHODS USED TO INSTALL THE TRACER WIRE DURING CONSTRUCTION, THE LOCATION OF THE TRACER WIRE MAY BE DIFFERENT THAN THE ACTUAL LOCATION OF THE SUBJECT UNDERGROUND UTILITY LINE, WHICH MAY NECESSITATE THE NEED FOR FURTHER SUE INVESTIGATION OR QL-A TEST HOLES. 3. NON-TRACEBLE FIBER OPTIC CONDUITS WERE RODDED USING A TRANSMITTER OR TRACER WIRE TO INTRODUCE CONDUCTIVE MATERIAL INTO THE LINES AND ALLOW FOR DESIGNATION. ELECTRONIC DEPTHS 1. ELECTRONIC DEPTHS SHOWN IN THESE PLANS ARE APPROXIMATE, CANNOT BE RELIED UPON FOR DESIGN OR CONSTRUCTION PURPOSES, AND ARE ONLY PROVIDED AS GUIDELINES FOR ADDITIONAL SUE WORK. THE PROJECT OWNER AND THEIR ENGINEER MUST VERIFY ALL ELECTRONIC DEPTHS WITH QL-A TEST HOLES PRIOR TO FINAL DESIGN OR CONSTRUCTION. 2. THE ELECTRONIC DEPTH, IF SHOWN HEREIN, IS A RANGE (FEET TO FEET), WHICH REFERS TO THE BEST AVAILABLE INFORMATION ON BURIED DEPTH AS COLLECTED FROM THE DESIGNATING EQUIPMENT. FOR METALLIC UTILITY LINES, THE DESIGNATING EQUIPMENT GENERALLY ESTIMATES THE BURIED DEPTH OF THE UTILITY BASED ON THE DISTANCE BETWEEN THE EQUIPMENT AND THE CENTER OF THE MAGNETIC FIELD (SIGNAL) FORMED AROUND THE UTILITY LINE. FOR NON-METALLIC LINES INTO WHICH A ROD OR SONDE WAS INTRODUCED, ESTIMATED DEPTHS ARE NOT PROVIDED. 3. SURVWEST HAS NOT STATED, IMPLIED, OR OTHERWISE COMMUNICATED TO ANY PARTY ANY ACCURACY OR RELIABILITY OF ANY ELECTRONIC DEPTHS BECAUSE THEY ARE DEPENDENT ON THE CALIBRATION AND MANUFACTURER'S SPECIFICATIONS OF THE DESIGNATING EQUIPMENT USED, THE DESIGNATOR'S EXPERIENCE AND ABILITIES, THE SITE CONDITIONS ENCOUNTERED DURING THE FIELD WORK, AND OTHER FACTORS SUCH THAT NO SPECIFIC ACCURACY OR RELIABILITY CAN BE DETERMINED. DATA LIMITATIONS 1. ALL QL-D, QL-C, AND/OR QL-B DATA DEPICTED IN THESE PLANS ARE INTENDED AS GUIDELINES FOR QL-A TEST HOLES OR OTHER UTILITY INVESTIGATION PRIOR TO FINAL DESIGN AND CONSTRUCTION BY OTHERS. THE EXACT LOCATIONS OF INDIVIDUAL SUBSURFACE UTILITY INFRASTRUCTURE SHOWN IN THESE PLANS ARE NOT CONFIRMED UNLESS THEY WERE VISUALLY EXPOSED AND SURVEYED, AND SUCH INFORMATION OBTAINED ONLY APPLIES TO THOSE SPECIFIC EXPOSED LOCATIONS OF THE SUBJECT UTILITY INFRASTRUCTURE. REFERENCED FILE: (MtnVista-Timberline-Bridge 2010 Topo NGVD88 ELEV) 2. SURVWEST PERFORMED THIS SUE PROJECT IN ACCORDANCE WITH THE ASCE 38-22 GUIDELINES (OR LATEST REVISION BY SAME OR DIFFERENT TITLE) AND CURRENT GENERALLY ACCEPTED INDUSTRY STANDARDS. HOWEVER, THE POSSIBILITY STILL EXISTS THAT SOME UTILITIES WERE NOT FOUND OR DEPICTED. 3. THE DEPICTED HORIZONTAL LIMITS OF BURIED UTILITIES ARE NOT NECESSARILY INDICATIVE OF THE UNDERGROUND HORIZONTAL LIMITS, WHICH CAN EXTEND SIGNIFICANTLY BEYOND WHAT IS SHOWN IN THESE PLANS. 4. SOME UTILITIES MAY BE DEPICTED OUTSIDE OF THE LIMITS OF THE SUE INVESTIGATION; THIS IS NOT AN INDICATION THAT ALL EXISTING UTILITIES ARE DEPICTED BEYOND THESE SUE INVESTIGATION LIMITS. 5. UTILITY ATTRIBUTE INFORMATION SUCH AS UTILITY OWNERSHIP, PIPE SIZE, OR PIPE MATERIAL ARE BASED ON INFORMATION GATHERED FROM AVAILABLE RECORDS. IN SOME CASES, THIS INFORMATION MAY BE OBSOLETE OR INACCURATE. THE USER OF THESE PLANS MUST VERIFY UTILITY ATTRIBUTE INFORMATION BY CONTACTING UTILITY OWNERS DURING THEIR UTILITY COORDINATION PROCESS. DESIGNATING EQUIPMENT 1. GEOPHYSICAL UTILITY DESIGNATION WAS PERFORMED USING THE RD 8100 RDL RECEIVER AND THE RD TX10 TRANSMITTER. 2. ADDITIONAL UTILITY INFORMATION WAS COLLECTED USING STANDARD FIELD EQUIPMENT SUCH AS SONDE, MEASURING TAPE, AND METAL DETECTORS. FIELD CONDITIONS 1. FIELD CONDITIONS WERE UNREMARKABLE THROUGHOUT THE DATA COLLECTION PERIOD. RECOMMENDATIONS FOR FURTHER INVESTIGATION 1. FURTHER UTILITY INVESTIGATION IS RECOMMENDED FOR UTILITIES DOCUMENTED IN RECORDS AND DEPICTED HEREIN AS QL-D BUT NOT INSPECTED OR DESIGNATED DURING FIELD WORK. SURVEY NOTES 1. THIS LOCATION SURVEY OF THE EXISTING UTILITY INFRASTRUCTURE DOES NOT REPRESENT A LAND SURVEY PLAT, AN IMPROVEMENT SURVEY PLAT, OR A BOUNDARY SURVEY. THIS LOCATION SURVEY IS BASED ON EXISTING PHYSICAL EVIDENCE THAT WAS PERFORMED ON 04/05/2024, BETWEEN 08/05/2024 - 08/06/2024, AND ON 09/06/2024. 2. THE SURVEY EQUIPMENT USED TO RECORD DESIGNATING MARKS, APPURTENANCES, AND OTHER SURFACE FEATURES IS KNOWN TO HAVE AN ACCURACY OF +/-0.2'. THIS SURVEY ACCURACY DOES NOT APPLY TO THE ACCURACY OF QLB DESIGNATING, ONLY TO THE ACCURACY OF THE SURVEYED MARKS. THE VERTICAL ACCURACY FOR QLA TEST HOLES IS KNOWN TO HAVE AN ACCURACY OF +/- 0.1', UNLESS OTHERWISE STATED HEREIN 3. THE NON-SUE PROJECT SURVEY WAS PERFORMED BY SURVWEST. 4. THE PROJECT SURVEY INFORMATION, INCLUDING COORDINATE SYSTEM, CONTROL POINTS, AND THE BASE FILE WAS PROVIDED TO SURVWEST BY THE CLIENT. ORTHOMETRIC HEIGHTS (ELEVATION) WERE ESTABLISHED BY GPS METHODS INCORPORATING A HIGH-RESOLUTION GEOID MODEL (GEOID18), NAD83(2011) DATUM. 5. HORIZONTAL COORDINATES ARE BASED ON CITY OF FORT COLLINS GROUND MASTER COORDINATE SYSTEM ; VALUES BEING REPORTED ARE GRID VALUES. 6. CONTROL POINTS ARE AS DESCRIBED IN TABLE 2 - SURVEY CONTROL POINTS BELOW. TABLE 2 - SURVEY CONTROL POINTS CERTIFICATION NOTE: THE UTILITY INFRASTRUCTURE DEPICTED HEREIN HAVE BEEN INVESTIGATED IN GENERAL COMPLIANCE WITH CI/ASCE 38-22, “STANDARD GUIDELINE FOR INVESTIGATING AND DOCUMENTING EXISTING UTILITIES”, AND THEY ARE DEPICTED AT THEIR ACHIEVED QUALITY LEVELS. THE EXACT LOCATIONS OF INDIVIDUAL SUBSURFACE UTILITY INFRASTRUCTURE SHOWN IN THESE PLANS ARE NOT CONFIRMED UNLESS THEY WERE VISUALLY EXPOSED AND SURVEYED, AND SUCH INFORMATION OBTAINED ONLY APPLIES TO THOSE SPECIFIC EXPOSED LOCATIONS OF THE SUBJECT UTILITY INFRASTRUCTURE.

EXHIBIT B 15 City of Ft Collins August Mountain Vista Drive and Timberline Road Culvert Replacement Bid Number: 10204 4 REVISION OF SECTION 108 PROSECUTION AND PROGRESS D. The following specifies the procedure for the determination of time extensions for unusually severe weather. The listing below defines the anticipated number of calendar days lost to adverse weather for each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data for the geographic location of the project. Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions A. The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse weather days that delay the work will be recorded on a day-to-day basis. It is assumed that the work will be carried out Mondays through Fridays (holidays accepted) unless an approved construction schedule or written authorization from the Owner indicates otherwise. The number of days of delayed work due to adverse weather or the impact thereof will then be compared to the monthly adverse weather schedule above. B. An actual adverse weather day must prevent work for 50 percent or more of the Contractor’s workday, delay work critical to the timely completion of the project and be documented by the Contractor. The City Representative observing the construction shall determine on a daily basis whether or not work can proceed or if work is delayed due to adverse weather or the effects thereof. The Contractor shall notify the Engineer in writing of any disagreement as to whether or not work can proceed on a given date, within 2 calendar days of that date. The Owner will use the above written notification in determining the number of working days for which work was delayed during each month. C. At the end of each month, if the number of working days for which work was delayed due to adverse weather exceeds that shown in the above schedule, a Change Order will be executed which increases the Contract Time. The number of work days delayed due to adverse weather or the impact thereof will then be converted to Calendar Days based on the contract completion day and date. This conversion assumes a 5- day work week, Mondays through Fridays, holidays excepted; should the Contractor have authorization to work weekends and/or holidays, and then the method of conversion of workdays to calendar days would take this into consideration. The contract time period will then be increased by the number of calendar days calculated above and a new contract completion day and date will be set. D. The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all weather- dependent activities. E. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the Owner shall make no monetary compensation for any costs to the Contractor arising out of such delays. The Contractor shall comply with the portions of the Contract Documents relating to his project schedule and amendments thereto which result from the "unusually severe" weather condition. F. Breakdowns in equipment or lack of performance by the Contractor will not be considered justification for an extension of time. Liquidated damages will be assessed as delineated elsewhere. G. The Contractor shall not be charged with liquidated damages or any excess cost when the delay in completion of the work is due to the following, and the Contractor has promptly given written notice of such delay to the Owner or Engineer. EXHIBIT B 16 City of Ft Collins August Mountain Vista Drive and Timberline Road Culvert Replacement Bid Number: 10204 5 REVISION OF SECTION 108 PROSECUTION AND PROGRESS No compensation or liquidated damages will be considered for actual Calendar Days lost, not in excess of the Anticipated Calendar Days lost identified in this section. A. To any preference, priority, or allocation order duly issued by the Owner. B. To unforeseeable causes beyond the control and without the fault or negligence of the Contractor, including but not restricted to, acts of God, or of the public enemy, acts of the Owner, acts of another Contractor in the performance of a contract with the Owner C. Fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather as provided above. D. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2, above. Subsection 108.05 shall include the following: The contractor shall schedule all work between 7:00 A.M. and 7:00 P.M. Monday through Friday, unless otherwise authorized by the Engineer The Contractor may make emergency repairs to provide protection of the work and traveling public at any time.

Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials i Report Summary Topic 1 Overview Statement 2 Project Description A geotechnical exploration has been performed for the proposed culvert and wing walls to be constructed near the intersection of Timberline Road and Mountain Vista Drive in Fort Collins, Colorado. Three borings were performed to depths of approximately 20 to 25½ feet below existing grades. Geotechnical Characterization Subsurface conditions encountered in our exploratory borings generally consisted of about 19 to 20 feet of lean clay with varying amounts of sand over about 5 feet of weathered claystone bedrock. Boring No. B-3 has about 9 feet of clayey sand, over sandy lean clay. Groundwater not observed during our field exploration. Geotechnical Overview Expansive soils and weathered claystone bedrock are present on this site; however, swell test results for samples obtained from our borings were generally low swelling to compressible. This report provides recommendations to help mitigate the effects of soil movement/heave associated with these materials. The risk can be mitigated by careful design, construction and maintenance practices; however, it should be recognized these procedures will not eliminate risk. The owner should be aware and understand pavements and/or utilities may be affected to some degree by the expansive soils and bedrock on this site. Comparatively loose, low relative density sand soils were encountered at a depth of approximately 7 feet below existing grade in Boring No. B-3. These materials present a risk for potential settlement of shallow foundations and other surficial improvements. These materials can also be susceptible to disturbance and loss of strength under repeated construction traffic loads and unstable conditions could develop. Rework or stabilization of loose soils may be required at some locations to provide adequate support for construction equipment and the proposed structure. Terracon should be contacted if these conditions are encountered to observe the conditions exposed and to provide guidance regarding stabilization (if needed).

Import materials (if needed) should be evaluated and approved by Terracon prior to delivery to the site. Shallow Foundations We believe the wing walls for the proposed box culvert can be supported on a shallow, spread footing foundation system, provided the soils beneath the wing walls and the box culvert are over-excavated to a depth of at least 1 foot below the bottom of footings and replaced with moisture conditioned, properly compacted engineered fill.

Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 1 Introduction This report presents the results of our subsurface exploration and Geotechnical Engineering services performed for the proposed culvert to be located near the intersection of Timberline Road and Mountain Vista Drive in Fort Collins, Colorado. The purpose of these services was to provide information and geotechnical engineering recommendations relative to: Subsurface soil and rock conditions Groundwater conditions Seismic site classification Site preparation and earthwork Demolition considerations Dewatering considerations Foundation design and construction Lateral earth pressures The geotechnical engineering Scope of Services for this project included the advancement of test borings, laboratory testing, engineering analysis, and preparation of this report. Drawings showing the site and boring locations are shown in the Site Location and Exploration Plan section of this report. The results of the laboratory testing performed on soil and bedrock samples obtained from the site during our field exploration are included on the boring logs and as separate graphs in the Exploration Results section. Project Description Our initial understanding of the project was provided in our proposal and was discussed during project planning. A period of collaboration has transpired since the project was initiated, and our final understanding of the project conditions is as follows: Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 2 Item Description Information Provided The project information described below is based on the following: Email and phone communication with Benesch. Mountain Vista and Timberline.kmz, provided by Benesch. Timberline Mountain Vista Culvert Replacement Scope.pdf, provided by Benesch and dated February 20, 2024. Preliminary site plans provided by Benesch, dated June 7, 2024 Project Description We understand a new culvert is planned to replace the existing 6-foot by 9-foot arch pipe for the Number 8 Outlet Ditch at the intersection of Mountain Vista Drive and Timberline Road. We understand the planned box culvert will be approximately 8 feet wide, 7 feet in height, and 160 feet long. Grading/Slopes Grading plans were not provided to Terracon at the time of this report. We anticipate cuts and fills on the order of about 5 feet or less will be required to achieve proposed grades. Deeper excavations could be required for some structural elements. Free-Standing Retaining Walls Wing walls are planned to be constructed at the ends of the culvert to achieve final grades. Wing walls are anticipated to be designed and constructed as reinforced concrete, cantilevered walls. Pavements No new pavements requiring design are anticipated. We anticipate existing roadway pavements/surfacing will be demolished as part of the installation of the culvert will be replaced per Larimer County specifications to a minimum thickness at least equal to the existing pavement/surfacing thickness. The asphalt core that was observed during this project was approximately 6 inches thick. Design Code AASHTO LRFD Bridge Design Specifications Terracon should be notified if any of the above information is inconsistent with the planned construction, especially the grading limits, as modifications to our recommendations may be necessary. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 3 Site Conditions The following description of site conditions is derived from our site visit in association with the field exploration and our review of publicly available geologic and topographic maps. Item Description Parcel Information The project site is located near the intersection of Timberline Road and Mountain Vista Drive in Fort Collins, Colorado. Latitude/Longitude (approximate): 40.61022° N, 105.02905° W See Site Location Existing Improvements Mountain Vista Drive spans over the ditch and has two, asphalt-paved drive lanes, with approximately 6-foot-wide shoulders on each side. Current Ground Cover The existing roadways are paved with asphalt, and shoulders are vegetated with native grasses and weeds. Existing Topography The alignment slopes towards the Number 8 Outlet Ditch. The interpolated ground surface elevations at the boring locations range from about El. 5,001 to El. 5,003 feet AMSL. Geotechnical Characterization We have developed a general characterization of the subsurface conditions based upon our review of the subsurface exploration, laboratory data, geologic setting and our understanding of the project. This characterization, termed GeoModel, forms the basis of our geotechnical calculations and evaluation of the site. Conditions observed at each exploration point are indicated on the individual logs. The individual logs can be found in the Exploration Results and the GeoModel can be found in the Figures attachment of this report. As part of our analyses, we identified the following model layers within the subsurface profile. For a more detailed view of the model layer depths at each boring location, refer to the GeoModel. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 4 Model Layer Layer Name General Description 1 Lean Clay Lean clay with varying amounts of sand; medium stiff to very stiff 2 Clayey Sand Clayey sand; very loose to medium dense 3 Weathered Bedrock Weathered claystone bedrock; medium stiff to stiff Groundwater Conditions The boreholes were observed while drilling and shortly after completion for the presence and level of groundwater. Groundwater was not observed during or after drilling. Groundwater conditions may change because of water levels within Number 8 Outlet Ditch, seasonal variations in rainfall, runoff, and other conditions not apparent at the time of drilling. Long-term groundwater monitoring was outside the scope of services for this project. Seismic Site Class The seismic design requirements for buildings and other structures are based on Seismic Design Category. Site Classification is required to determine the Seismic Design Category for a structure. The Site Classification is based on the upper 100 feet of the site profile defined by a weighted average value of either shear wave velocity, standard penetration resistance, or undrained shear strength in accordance with Section 20.4 of ASCE 7 and the International Building Code (IBC). Based on the soil and bedrock properties observed at the site as described on the exploration logs and laboratory test results, our professional opinion is a Seismic Site Classification of D be considered for the project. Subsurface explorations at this site were extended to a maximum depth of 25½ feet. The site properties below the boring depth to 100 feet were estimated based on our experience and knowledge of geologic conditions of the general area. Additional deeper borings or geophysical testing may be performed to confirm the conditions below the current boring depth. Corrosivity Results of water-soluble sulfate testing indicate Exposure Class S0 according to ACI 318. ASTM Type I, IL, or II portland cement should be specified for all project concrete on and below grade. Foundation concrete should be designed for low sulfate exposure in accordance with the provisions of the ACI Design Manual, Section 318, Chapter 4. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 5 Numerous sources are available to characterize corrosion potential to buried metals using the parameters above. ANSI/AWWA is commonly used for ductile iron, while threshold values for evaluating the effect on steel can be specific to the buried feature (e.g., piling, culverts, welded wire reinforcement, etc.) or agency for which the work is performed. Imported fill materials may have significantly different properties than the site materials noted above and should be evaluated if expected to be in contact with metals used for construction. Consultation with a NACE certified corrosion professional is recommended for buried metals on the site. Mapping by the NRCS includes qualitative severity of corrosion to concrete and steel. Based on this source, the near-surface materials are rated “Low” for corrosion to concrete and “Moderate” for corrosion of steel. Geotechnical Overview Based on subsurface conditions encountered in the borings, the site appears suitable for the proposed construction from a geotechnical point of view provided certain precautions and design and construction recommendations described in this report are followed. We have identified several geotechnical conditions that could impact design, construction and performance of the proposed structures and other site improvements. These included expansive soils and weathered claystone bedrock, and potentially loose, low relative density sand soils. These conditions will require particular attention in project planning, design and during construction and are discussed in greater detail in the following sections. Expansive Soils and Bedrock Expansive soils and weathered claystone bedrock are present on this site; however, swell test results for samples obtained from our borings were generally low swelling to compressible. This report provides recommendations to help mitigate the effects of soil shrinkage and expansion. However, even if these procedures are followed, some movement and cracking in the structures, pavements, and flatwork (if any) is possible. The severity of cracking and other damage such as uneven flatwork will probably increase if modification of the site results in excessive wetting or drying of the expansive clays and/or weathered claystone bedrock. Eliminating the risk of movement and cosmetic distress is generally not feasible, but it may be possible to further reduce the risk of movement if significantly more expensive measures are used during construction. It is imperative the recommendations described in section Grading and Drainage section of the Earthwork section of this report be followed to reduce potential movement. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 6 Low Strength Soils Comparatively loose, low relative density sand soils were encountered at a depth of approximately 7 feet below existing grade in Boring No. B-3. Loose and/or soft soils could also exist at other locations on the site and extend to greater depths particularly within the ditch itself. These materials present a risk for potential settlement of shallow foundations and other surficial improvements. These materials can also be susceptible to disturbance and loss of strength under repeated construction traffic loads and unstable conditions could develop. Stabilization of soft soils may be required at some locations to provide adequate support for construction equipment and proposed structures. Terracon should be contacted if these conditions are encountered to observe the conditions exposed and to provide guidance regarding stabilization (if needed). Foundation Recommendations Based on the results of the borings and our understanding of the project, we believe the wing walls for the proposed box culvert can be supported by a shallow, spread footing foundation system provided the soils are over-excavated to a depth of at least 1 foot below the bottom of footings and replaced with moisture conditioned, properly compacted engineered fill. On-site soils free of any deleterious materials are suitable for use as engineered fill below foundations. Design recommendations for foundations for the proposed structure and related structural elements are presented in the following sections of this report. To reduce the potential for differential movements between the culvert and wing walls due to the presence of potentially loose soils at/near the anticipated culvert floor elevation, we recommend the soils be over-excavated to a depth of at least 1 foot below the bottom of the culvert and replaced with moisture conditioned, properly compacted engineered fill. The recommendations contained in this report are based upon the results of field and laboratory testing (presented in the Exploration Results), engineering analyses, and our current understanding of the proposed project. The General Comments section provides an understanding of the report limitations. Earthwork Earthwork is anticipated to include demolition, site preparation, excavations, subgrade preparation, soil stabilization (if needed), and engineered fill placement. The following sections provide recommendations for use in the preparation of specifications for the project. Recommendations include critical quality criteria, as necessary, to render the site in the state considered in our geotechnical engineering evaluation for foundations. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 7 Demolition Demolition of the existing roadway and drainage structure should include complete removal of all foundation systems, any other below-grade structural elements, and existing roadway pavements/surfacing within the proposed construction area. This should include removal of any utilities to be abandoned along with any loose utility trench backfill or loose backfill found adjacent to existing foundations or structures. All materials derived from the demolition of existing structures and roadways should be removed from the site. Site Preparation Prior to placing fill, existing vegetation, topsoil, and root mats, and any other deleterious materials should be removed from the proposed construction area. Complete stripping of the topsoil should be performed in areas of new construction. While not encountered in our borings, any existing, undocumented fill if encountered should also be completed removed from within the proposed construction area. Stripped organic materials should be wasted from the site or used to re-vegetate landscaped areas or exposed slopes after completion of grading operations. Prior to the placement of fills, the site should be graded to create a relatively level surface to receive fill, and to provide for a relatively uniform thickness of fill beneath proposed structures. Where fill is placed on existing slopes steeper than 5H:1V (Horizontal:Vertical), benches should be cut into the existing slopes prior to fill placement. The benches should have a minimum vertical face height of 1 foot and a maximum vertical face height of 3 feet and should be cut wide enough to accommodate the compaction equipment. This benching will help provide a positive bond between the fill and natural soils and reduce the possibility of failure along the fill/natural soil interface. Although no evidence of fill or underground facilities (such as septic tanks, cesspools, basements, and utilities) was observed during the exploration and site reconnaissance, such features could be encountered during construction. If unexpected fills or underground facilities are encountered, such features should be removed, and the excavation thoroughly cleaned prior to backfill placement and/or construction. Excavation We anticipate excavations for the proposed construction can be accomplished with conventional earthmoving equipment. Excavations into the on-site soils will encounter loose soil conditions with possible caving conditions. The bottom of excavations should be thoroughly cleaned of loose/disturbed materials prior to backfill placement and/or construction. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 8 Any over-excavation that extends below the bottom of culvert and wing wall foundation elevations should extend laterally beyond all edges of the foundations at least 8 inches per foot of over-excavation depth below the foundation base elevation. The over- excavation should be backfilled to the foundation and culvert base elevation in accordance with the recommendations presented in this report. Depending upon depth of excavation and seasonal conditions, surface water infiltration and/or groundwater may be encountered in excavations on the site. We anticipate pumping from sumps may be utilized to control water within excavations. Well points may be required for significant groundwater flow, or where excavations penetrate groundwater to a significant depth. Groundwater was not encountered during the time of our field exploration; however, we anticipate groundwater levels in the Number 8 Outlet Ditch to rise in different times of the year. The subgrade soil conditions should be evaluated during the excavation process and the stability of the soils determined at that time by the contractors’ Competent Person as defined by OSHA. Slope inclinations flatter than the OSHA maximum values may have to be used. The individual contractor(s) should be made responsible for designing and constructing stable, temporary excavations as required to maintain stability of both the excavation sides and bottom. All excavations should be sloped or shored in the interest of safety following local, and federal regulations, including current OSHA excavation and trench safety standards. As a safety measure, we recommend all vehicles and soil piles be kept a minimum lateral distance from the crest of the slope equal to the slope height. The exposed slope face should be protected against the elements. Subgrade Preparation After site preparation, removal of existing, undocumented fill (if necessary), and completion of the recommended over-excavation, the top 10 inches of the exposed ground surface should be scarified, moisture conditioned, and compacted to at least 95 percent of the maximum dry unit weight as determined by AASHTO T99 before any new fill, roadway embankment, or foundation is placed or constructed. Large areas of prepared subgrade should be proof rolled prior to new construction. Proof rolling is not required in areas which are inaccessible to proof rolling equipment. Subgrades should be proof rolled with an adequately loaded vehicle such as a fully- loaded tandem-axle dump truck. Proof rolling should be performed under the observation of the Geotechnical Engineer or representative. Areas excessively deflecting under the proof roll should be delineated and subsequently addressed by the Geotechnical Engineer. Excessively wet or dry material should either be removed or moisture conditioned and compacted. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 9 After the bottom of the excavation has been prepared as recommended above, engineered fill can be placed to bring the subgrade to the desired grade. Engineered fill should be placed in accordance with the recommendations presented in subsequent sections of this report. The stability of the subgrade may be affected by precipitation, repetitive construction traffic or other factors. If unstable conditions develop, workability may be improved by scarifying and drying. Alternatively, over-excavation of wet zones and replacement with granular materials may be used, or crushed gravel and/or rock can be tracked or “crowded” into the unstable surface soil until a stable working surface is attained. Use of geosynthetics could also be considered as a stabilization technique. Lightweight excavation equipment may also be used to reduce subgrade pumping. Subgrade Stabilization Methods of subgrade stabilization/improvement, as described below, could include scarification, moisture conditioning and compaction, removal of unstable materials and replacement with granular fill (with or without geosynthetics), and chemical treatment. The appropriate method of improvement, if required, would be dependent on factors such as schedule, weather, the size of area to be stabilized, and the nature of the instability. More detailed recommendations can be provided during construction as the need for subgrade stabilization occurs. Performing site grading operations during warm seasons and dry periods would help reduce the amount of subgrade stabilization required. If the exposed subgrade is unstable during proof rolling operations, it could be stabilized using one of the methods described below. Scarification and Compaction - It may be feasible to scarify, dry, and compact the exposed soils. The success of this procedure would depend primarily upon favorable weather and sufficient time to dry the soils. Stable subgrades likely would not be achievable if the thickness of the unstable soil is greater than about 1 foot, if the unstable soil is at or near groundwater levels, or if construction is performed during a period of wet or cool weather when drying is difficult. Crushed Stone - The use of crushed stone or crushed concrete is a common procedure to improve subgrade stability. Typical undercut depths would be expected to range from about 6 to 24 inches below finished subgrade elevation. Crushed stone and/or concrete can be tracked or “crowded” into the unstable subgrade until a stable working surface is attained. The use of high modulus geosynthetics (i.e., geotextile or geogrid) could also be considered after underground work such as utility construction is completed. Prior to placing the geosynthetic, we recommend all below-grade construction, such as utility line installation, be completed to avoid damaging the geosynthetic. Equipment should Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 10 not be operated above the geosynthetic until one full lift of crushed stone fill is placed above it. Chemical Treatment - Improvement of subgrades with portland cement, or fly ash could be considered for improving unstable soils. Chemical treatment should be performed by a pre-qualified contractor having experience with successfully treating subgrades in the project area on similar sized projects with similar soil conditions. Results of chemical analysis of the chemical treatment materials should be provided to the Geotechnical Engineer for review prior to use. The hazards of chemicals blowing across the site or onto adjacent properties should also be considered. Additional testing would be needed to develop specific recommendations to improve subgrade stability by blending chemicals with the site soils. Additional testing could include, but not be limited to, determining the most suitable chemical treating agent, the optimum amounts required, the presence of sulfates in the soil, and freeze-thaw durability of the subgrade. Further evaluation of the need and recommendations for subgrade stabilization can be provided during construction as the geotechnical conditions are exposed. Fill Material Types Fill for this project should consist of engineered fill. Engineered fill is fill that meets the criteria presented in this report and has been properly documented. On-site soils free of deleterious materials or approved granular and low plasticity cohesive imported materials may be used as fill material. Weathered bedrock excavated during site development and construction can be reused as fill provided the material is broken down and thoroughly processed to a “soil-like” consistency, with no particles greater than 2 inches in size. The earthwork contractor should expect significant mechanical processing and moisture conditioning of the site soils and/or bedrock will be needed to achieve proper compaction. Imported fill materials (if required) should meet the following material property requirements. Regardless of its source, compacted fill should consist of approved materials that are free of organic matter and debris. Frozen material should not be used, and fill should not be placed on a frozen subgrade. Gradation Percent Finer by Weight (ASTM C136) 3 ”100 1 ”70-100 No. 4 Sieve 30-100 No. 200 Sieve 60 (max.)

Plasticity Index 15 (max.) Other import fill material types may be suitable for use on the site depending upon proposed application and location on the site and could be tested and approved for use on a case-by-case basis. Fill Placement and Compaction Requirements Engineered fill should be placed and compacted in horizontal lifts, using equipment and procedures that will produce recommended moisture contents and densities throughout the lift. Item Description Maximum Lift Thickness 9 inches or less in loose thickness when heavy, self-propelled compaction equipment is used 4 to 6 inches in loose thickness when hand-guided equipment (i.e., jumping jack or plate compactor) is used Minimum Compaction Requirements 1 Engineered Fill : At least 95% of the maximum dry unit weight as determined by AASHTO T99. Engineered Fill 8 Feet or Greater: At least 98% of the maximum dry unit weight as determined by AASHTO T99 for the entire depth of fill in areas receiving 8 feet of fill or greater. Aggregate Base Course: At least 95% of maximum dry unit weight as determined by AASHTO T180. Water Content Range 2,3 Cohesive (clay): -1% to +3% of optimum moisture content Granular (sand): -3% to +3% of optimum moisture content 1.We recommend engineered fill be tested for moisture content and compaction during placement. If the results of the in-place density tests indicate the specified moisture or compaction limits have not been met, the area represented by the test should be reworked and retested as required until the specified moisture and compaction requirements are achieved. 2.Moisture conditioned clay materials should not be allowed to dry out. A loss of moisture within these materials could result in an increase in the material’s expansive potential. Subsequent wetting of these materials could result in undesirable movement. 3.Specifically, moisture levels should be maintained low enough to allow for satisfactory compaction to be achieved without the fill material pumping when proof rolled. Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 12 Utility Trench Backfill Any loose, soft, or unsuitable materials encountered at the bottom of utility trench excavations should be removed and replaced with engineered fill or bedding material in accordance with public works specifications for the utility to be supported. This recommendation is particularly applicable to utility work where settlement control of the utility is critical. On-site materials are considered suitable for backfill of utility and pipe trenches provided the material is free of organic matter and deleterious substances. Utility trench backfill should be placed and compacted as discussed earlier in this report. Compaction of initial lifts should be accomplished with hand-operated tampers or other lightweight compactors. Flooding or jetting for placement and compaction of backfill is not recommended. We recommend a representative of the Geotechnical Engineer provide full-time observation and compaction testing of trench backfill within construction areas. Grading and Drainage Grades should be adjusted to provide effective drainage away from the proposed structure and roadway during construction. Infiltration of water into foundation excavations must be prevented during construction. Backfill against foundations and walls should be properly compacted and free of all construction debris to reduce the possibility of moisture infiltration. After construction of the proposed structure and prior to project completion, we recommend verification of final grading be performed to document positive drainage, as described above, has been achieved. Maximum grades practical should be used for roadways to prevent areas where water can pond. Care should be taken to prevent the infiltration of surface water into the roadway subgrade and behind the culvert wing walls. Earthwork Construction Considerations Upon completion of filling and grading, care should be taken to maintain the subgrade water content prior to construction. Construction traffic over the completed subgrades should be avoided. The site should also be graded to prevent ponding of surface water on the prepared subgrades or in excavations. Water collecting over or adjacent to construction areas should be removed. If the subgrade freezes, desiccates, saturates, or is disturbed, the affected material should be removed, or the materials should be scarified, moisture conditioned, and recompacted.

Observation should include documentation of adequate removal of surficial materials (vegetation, topsoil, and existing pavements), subgrade stabilization, as well as proof rolling and mitigation of unsuitable areas delineated by the proof roll. Each lift of compacted fill should be tested, evaluated, and reworked, as necessary, as recommended by the Geotechnical Engineer prior to placement of additional lifts. In areas of foundation excavations, the bearing subgrade and exposed conditions at the base of the recommended over-excavation should be evaluated by the Geotechnical Engineer. If unanticipated conditions are observed, the Geotechnical Engineer should prescribe mitigation options. In addition to the documentation of the essential parameters necessary for construction, the continuation of the Geotechnical Engineer into the construction phase of the project provides the continuity to maintain the Geotechnical Engineer’s evaluation of subsurface conditions, including assessing variations and associated design changes. Shallow Foundations If the site has been prepared in accordance with the requirements noted in Earthwork, the following design parameters are applicable for shallow foundations. Spread Footings – Design Recommendations Item Description Maximum Net Allowable Bearing Pressure 1 1,500 psf Required Bearing Stratum 2 1 foot of moisture conditioned ,properly compacted engineered fill Minimum Foundation Dimensions Continuous: 18 inches Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 14 Item Description Lateral Earth Pressure Coefficients 3 On -site clay soil: Active, Ka = 0.36 Passive, Kp = 2.77 At-rest, Ko = 0.53 Sliding Resistance 4 On -site clay soil: = 0.43 Moist Soil Unit Weight On -site clay soil and engineered fill: = 100 pcf Minimum Embedment Below Finished Grade 5 36 inches Estimated Total Movement 6 About 1 inch or less Estimated Differential Movement 6 About ½ to ¾ of total movement 1.The maximum net allowable bearing pressure is the pressure in excess of the minimum surrounding overburden pressure at the footing base elevation. Values assume exterior grades are no steeper than 20% within 10 feet of structure. The design bearing pressure applies to a dead load plus design live load condition. The design bearing pressure may be increased by one-third when considering total loads that include wind or seismic conditions. 2.Unsuitable or soft/loose soils should be over-excavated and replaced with engineered fill per the recommendations presented in Earthwork. 3.Use of lateral earth pressures require the sides of the excavation for the spread footing foundation to be nearly vertical and the concrete placed neat against these vertical faces or the footing forms be removed and compacted engineered fill be placed against the vertical footing face. Assumes no hydrostatic pressure. The lateral earth pressure coefficients are ultimate values and do not include a factor of safety. The foundation designer should include the appropriate factors of safety. 4.For fine-grained materials, lateral resistance using cohesion should not exceed ½ the dead load. 5.Embedment necessary to minimize the effects of frost and/or seasonal water content variations. For sloping ground, maintain depth below the lowest adjacent exterior grade within 5 horizontal feet of the structure. 6.The estimated movements presented above assume the maximum footing width is 5 feet for continuous footings. Larger foundation footprints will likely require reduced net allowable soil bearing pressures to reduce risk for potential settlement. Footings should be proportioned to reduce differential foundation movement. As discussed, total movement resulting from the assumed structural loads is estimated to be on the order of about 1 inch. Additional foundation movements could occur if water from any source infiltrates the foundation soils; therefore, proper drainage should be provided in the final design and during construction and throughout the life of the structure. Failure to maintain the proper drainage as recommended in the Grading and Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 15 Drainage section of the Earthwork section of this report will nullify the movement estimates provided above. Any over-excavation that extends below the bottom of foundation elevation should extend laterally beyond all edges of the foundations at least 8 inches per foot of over- excavation depth below the foundation base elevation. The over-excavation should be backfilled to the foundation base elevation in accordance with the recommendations presented in this report. Shallow Foundation Construction Considerations As noted in Earthwork, foundation excavations should be evaluated under the observation of the Geotechnical Engineer. The base of all foundation excavations should be free of water and loose soil, prior to placing concrete. Concrete should be placed soon after excavating to reduce bearing soil disturbance. Care should be taken to prevent wetting or drying of the bearing materials during construction. Excessively wet or dry material or any loose/disturbed material in the bottom of foundation excavations should be removed/reconditioned before foundation concrete is placed. To reduce the potential of “pumping” and softening of the foundation soils at the foundation bearing level and the requirement for corrective work, we suggest the foundation excavation be completed remotely with a track-hoe operating outside of the excavation limits. Foundation elements should be reinforced as necessary to reduce the potential for distress caused by differential foundation movement. Unstable subgrade conditions encountered in foundation excavations should be observed by Terracon to assess the subgrade and provide suitable alternatives for stabilization. Typical methods of stabilization/improvement are presented in the Subgrade Stabilization section of Earthwork. Lateral Earth Pressures Design Parameters Structures with unbalanced backfill levels on opposite sides should be designed for earth pressures at least equal to values indicated in the following table. Earth pressures will be influenced by structural design of the walls, conditions of wall restraint, methods of construction, and/or compaction and the strength of the materials being restrained. Two wall restraint conditions are shown in the diagram below. Active earth pressure is commonly used for design of free-standing cantilever retaining walls and assumes wall Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 16 movement. The “at-rest” condition assumes no wall movement and is commonly used for basement walls, loading dock walls, or other walls restrained at the top. The recommended design lateral earth pressures do not include a factor of safety and do not provide for possible hydrostatic pressure on the walls (unless stated). Lateral Earth Pressure Design Parameters Earth Pressure Condition 1 Coefficient for Backfill Type 2 Surcharge Pressure 3 p1 (psf) Equivalent Fluid Pressures (psf)2,4 Unsaturated 5 Submerged 5 Active (Ka)Fine Grained -0.36 (0.36)S (35)H (75)H At-Rest (Ko)Fine Grained -0.53 (0.53)S (50)H (80)H Passive (Kp)Fine Grained – 2.77 --------- 1.For active earth pressure, wall must rotate about base, with top lateral movements 0.002 H to 0.004 H, where H is wall height. For passive earth pressure, wall must move horizontally to mobilize resistance. Fat clay or other expansive soils should not be used as backfill behind the wall. 2.Uniform, horizontal backfill, with a maximum unit weight of 100 pcf for cohesive soils. 3.Uniform surcharge, where S is surcharge pressure. 4.Loading from heavy compaction equipment is not included. 5.To achieve “Unsaturated” conditions, follow guidelines in Subsurface Drainage for Below-Grade Walls below. “Submerged” conditions are recommended when drainage behind walls is not incorporated into the design. To control hydrostatic pressure behind the walls, we recommend a drain be installed at the foundation and wing walls with a collection pipe leading to a reliable discharge. If this is not possible, then combined hydrostatic and lateral earth pressures should be calculated for backfill using the submerged equivalent fluid pressures presented in the above table for active and at-rest conditions. These pressures do not include the influence of surcharge, equipment, or traffic loading, which should be added. Heavy Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 17 equipment should not operate within a distance closer than the exposed height of retaining walls to prevent lateral pressures more than those provided. The lateral earth pressure recommendations given in this section are applicable to the design of rigid retaining walls subject to slight rotation, such as cantilever, or gravity type concrete walls. These recommendations are not applicable to the design of modular block - geogrid reinforced backfill walls (also termed MSE walls). Recommendations covering these types of wall systems are beyond the scope of services for this assignment. However, we would be pleased to develop a proposal for evaluation and design of such wall systems upon request. General Comments Our analysis and opinions are based upon our understanding of the project, the geotechnical conditions in the area, and the data obtained from our site exploration. Variations will occur between exploration point locations or due to the modifying effects of construction or weather. The nature and extent of such variations may not become evident until during or after construction. Terracon should be retained as the Geotechnical Engineer, where noted in this report, to provide observation and testing services during pertinent construction phases. If variations appear, we can provide further evaluation and supplemental recommendations. If variations are noted in the absence of our observation and testing services on-site, we should be immediately notified so that we can provide evaluation and supplemental recommendations. Our Scope of Services does not include either specifically or by implication any environmental or biological (e.g., mold, fungi, bacteria) assessment of the site or identification or prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the potential for such contamination or pollution, other studies should be undertaken. Our services and any correspondence are intended for the sole benefit and exclusive use of our client for specific application to the project discussed and are accomplished in accordance with generally accepted geotechnical engineering practices with no third- party beneficiaries intended. Any third-party access to services or correspondence is solely for information purposes to support the services provided by Terracon to our client. Reliance upon the services and any work product is limited to our client and is not intended for third parties. Any use or reliance of the provided information by third parties is done solely at their own risk. No warranties, either express or implied, are intended or made. Site characteristics as provided are for design purposes and not to estimate excavation cost. Any use of our report in that regard is done at the sole risk of the excavating cost estimator as there may be variations on the site that are not apparent in the data that Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials 18 could significantly effect excavation cost. Any parties charged with estimating excavation costs should seek their own site characterization for specific purposes to obtain the specific level of detail necessary for costing. Site safety and cost estimating including excavation support and dewatering requirements/design are the responsibility of others. Construction and site development have the potential to affect adjacent properties. Such impacts can include damages due to vibration, modification of groundwater/surface water flow during construction, foundation movement due to undermining or subsidence from excavation, as well as noise or air quality concerns. Evaluation of these items on nearby properties are commonly associated with contractor means and methods and are not addressed in this report. The owner and contractor should consider a preconstruction/precondition survey of surrounding development. If changes in the nature, design, or location of the project are planned, our conclusions and recommendations shall not be considered valid unless we review the changes and either verify or modify our conclusions in writing.

B-1 and B-3)25 to 25.5 Near each end of the proposed culvert alignment 1 (Boring No. B-2)20 Existing roadway Boring Layout and Elevations: Terracon personnel provided the boring layout using handheld GPS equipment (estimated horizontal accuracy of about ±10 feet) and referencing existing site features. Approximate ground surface elevations were estimated using Google Earth/USGS topographic map. If surface elevations and a more precise boring layout are desired, we recommend the borings be surveyed. Subsurface Exploration Procedures: We advanced the borings with a truck-mounted drill rig using solid-stem, continuous-flight augers. Four samples were obtained in the upper 10 feet of each boring and at intervals of 5 feet thereafter. In the split-barrel sampling procedure, a standard 2-inch outer diameter split-barrel sampling spoon was driven into the ground by a 140-pound automatic hammer falling a distance of 30 inches. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18-inch penetration is recorded as the Standard Penetration Test (SPT) resistance value. The SPT resistance values, also referred to as N-values, are indicated on the boring logs at the test depths. For the modified California barrel sampling procedure, a 2½-inch outer diameter split-barrel sampling spoon is used for sampling. California barrel sampling procedures are similar to standard split-barrel sampling procedures; however, blow counts are typically recorded for 6-inch intervals for a total of 12 inches of penetration. Modified California barrel sampler blow counts are not considered N-values. The samples were placed in appropriate containers and taken to our soil laboratory for testing and classification by a Geotechnical Engineer. For safety purposes, Boring Nos. B-1 and B-3 were backfilled with auger cuttings after their completion. Boring No. B-2 was backfilled with flowable fill and patched with utilibond glue and an asphalt core. We also observed the boreholes while drilling and at the completion of drilling for the presence of groundwater. Groundwater was not observed at these times in the boreholes. The sampling depths, penetration distances, and other sampling information was recorded on the field boring logs. The samples were placed in appropriate containers and Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials taken to our soil laboratory for testing and classification by a Geotechnical Engineer. Our exploration team prepared field boring logs as part of the drilling operations. These field logs included visual classifications of the materials observed during drilling and our interpretation of the subsurface conditions between samples. Final boring logs were prepared from the field logs. The final boring logs represent the Geotechnical Engineer's interpretation of the field logs and include modifications based on observations and tests of the samples in our laboratory. Laboratory Testing The project engineer reviewed the field data and assigned laboratory tests. The laboratory testing program included the following types of tests: Moisture Content Dry Unit Weight Atterberg Limits One-dimensional Swell Water-soluble Sulfates The laboratory testing program often included examination of soil samples by an engineer and/or geologist. Based on the results of our field and laboratory programs, we described and classified the soil samples in accordance with the Unified Soil Classification System. A brief description of this classification system as well as the General Notes can be found in the Supporting Information section. Laboratory test results are indicated on the boring logs and are presented in depth in the Exploration Results section. Laboratory tests are performed in general accordance with applicable local standards or other acceptable standards. In some cases, variations to methods are applied as a result of local practice or professional judgement. Rock classification was conducted using locally accepted practices for engineering purposes. Boring log rock classification was determined using the Description of Rock Properties.

See Exploration and Testing Procedures in the report for the methods used to locate the exploration points for this project. Surface elevation data annotated with +/- indicates that no actual topographical survey was conducted to confirm the surface elevation. Instead, the surface elevation was approximately determined from topographic maps of the area. Soil classification as noted on the soil boring logs is based Unified Soil Classification System. Where sufficient laboratory data exist to classify the soils consistent with ASTM D2487 "Classification of Soils for Engineering Purposes" this procedure is used. ASTM D2488 "Description and Identification of Soils (Visual-Manual Procedure)" is also used to classify the soils, particularly where insufficient laboratory data exist to classify the soils in accordance with ASTM D2487. In addition to USCS classification, coarse grained soils are classified on the basis of their in-place relative density, and fine-grained soils are classified on the basis of their consistency. See "Strength Terms" table below for details. The ASTM standards noted above are for reference to methodology in general. In some cases, variations to methods are applied as a result of local practice or professional judgment. Exploration/field results and/or laboratory test data contained within this document are intended for application to the project as described in this document. Use of such exploration/field results and/or laboratory test data should not be used independently of this document.

Geotechnical Engineering Report Timberline Culvert Replacement | Fort Collins, Colorado August 27, 2024 | Terracon Project No. 20245020 Facilities | Environmental |Geotechnical | Materials Rock Classification Notes WEATHERING Term Description Fresh Mineral crystals appear bright; show no discoloration. Features show little or now staining on surfaces. Discoloration does not extend into intact rock. Slightly weathered Rock generally fresh except along fractures. Some fractures stained and discoloration may extend <0.5 inches into rock. Moderately weathered Significant portions of rock are dull and discolored. Rock may be significantly weaker than in fresh state near fractures. Soil zones of limited extent may occur along some fractures. Highly weathered Rock dull and discolored throughout. Majority of rock mass is significantly weaker and has decomposed and/or disintegrated; isolated zones of stronger rock and/or soil may occur throughout. Completely weathered All rock material is decomposed and/or disintegrated to soil. The rock mass or fabric is still evident and largely intact. Isolated zones of stronger rock may occur locally.
