If you have questions about any comments, you may contact the individual commenter or direct your questions through the Project Planner, Jason Holland, at 970-224-6126 or jholland@fcgov.com. Comment Summary: Comment Responses: Ripley Design, Kimley-Horn, Ware Malcomb, ESC, Core Spaces Department: Engineering Development Review Contact: Marc Virata, 970-221-6567, mvirata@fcgov.com Topic: General Comment Number: 3 Comment Originated: 12/23/2016 06/16/2017: Carried over as unresolved. Response: Parkway along Elizabeth has been revised to be indicated as an “access easement” on plan documents and plat. 03/08/2017: The plat call out a 2 foot parkway easement, which should be indicated as an "access easement" (also on the other documents that reference it as well). 12/23/2016: The cross section for the West Elizabeth Enhanced Travel Corridor Plan (ETC) specifies an area behind the curb of 12 feet. While acknowledging that the plan would appear to show the road narrowing and the future implementation of the corridor plan under this premise would then be at 12 feet, the concern at this time is that the project isn't funded to implement the plan, and there may be the realization that the narrowing of the roadway isn't a cost effective approach to implement the ETC. As a result, we would want to ensure that an equivalent sidewalk area of 12 feet behind the curb is provided at this time, instead of the 10 feet shown, requiring the offset of the landscape 2 wall and plaza area 2 feet further south than presently shown. (As Figure 16-1 of LCUASS requires the horizontal clearance of 2 feet from the back of sidewalk to a wall, this additional 2 foot of widening also accomplishes the horizontal clearance requirement from walls to a sidewalk). Additional right-of-way wouldn't necessarily need to be dedicated, we would be OK with the first 2 feet of the 15 foot utility easement also being an access easement. Comment Number: 8 Comment Originated: 12/23/2016 06/16/2017: The response indicated that the only letter of intent needed is from the property owner to the south. This should be provided prior to scheduling a public hearing per #15 of the PDP submittal requirements through the following link: http://www.fcgov.com/developmentreview/pdf/pdp_submittal_req_11.18.14.pdf ?1450456080 Response: Easement agreement with neighbor for signature. Email record has been provided on CD to show they are in agreeance while we wait for signature. 03/08/2017: I didn't find any letters of intent from abutting property owners. In general an exhibit of what the identified offsite work is needed from specific property owners would be beneficial for review. In addition, we should be provided information/documentation of what the language of all existing offsite easements allows (such as the private utility access and shared parking easement on the property to the east which the development is tying into). 12/23/2016: The grading plan does show TW labels with elevations that would appear to indicate top of wall elevations. If so, it appears that these walls are built on the property line and would need to excavate offsite in order to build, needing offsite easements and letters of intent from those property owners prior to hearing (this may also be needed for offsite grading that would be needed from the previous comment.) Comment Number: 16 Comment Originated: 06/16/2017 06/16/2017: The new driveway onto Elizabeth Street does not correctly reflect the tie in to the walk to the west. The proposal reflects pre-Uptown Plaza sidewalk widths, but with the approved Uptown Plaza plans, the sidewalk is further widened. Please have the design reflect the approved Uptown Plaza plans to tie into. Response: Sidewalk connection to the west along Elizabeth Street has been revised to reflect the widened, newly constructed Uptown Plaza plans. Comment Number: 17 Comment Originated: 06/16/2017 06/16/2017: The new driveway onto Elizabeth Street should be designed in accordance with our high volume drive type IV standard (707.2) in LCUASS. Please ensure the detail is included in the details sheet and the plans reflect its design. Additionally, Table 8-2 of LCUASS requires a 20' curb return radii, which does not appear to be met here. Response: New driveway onto Elizabeth Street is designed in accordance with the high volume drive type IV standard (707.2) in LCUASS. Curb radii are 20’. Comment Number: 18 Comment Originated: 06/16/2017 06/16/2017: The new driveway onto Elizabeth Street appears to meet warrants for a right turn into the driveway in accordance with Table 8-4 of LCUASS. In additional access spacing requirements are not met under Table 7-3 of 3 LCUASS. Either the project should address these standards, or submit variance request(s) for evaluation. Response: Variance request for right turn lane on Elizabeth is included with this resubmittal. Comment Number: 19 Comment Originated: 06/16/2017 06/16/2017: In general, Engineering is of the view that work on other off-site properties outside of the boundaries of the subdivision plat require letters of intent prior to scheduling a public hearing based upon 2.2.3(C) of the Land Use Code and the PDP master list previously referenced. Response: See comment 8 response above.

Response: See revised landscape plan, this new design includes more landscape sf than previous Comment Number: 19 Comment Originated: 06/14/2017 06/14/2017: Environmental Planning has no further comments at this time and is ready for Final Plan. Response: Thanks Topic: Landscape Plans Comment Number: 15 Comment Originated: 06/14/2017 06/14/2017: Please provide more plan details for those landscape amenities or features that are to be included on the rooftop outdoor space. Response: Rooftop amenity space is designed by third party and will be available for FDP Comment Number: 16 Comment Originated: 06/14/2017 06/14/2017: Please add an additional note or indicator on landscape plan sheet 5 of 19 that all trees are to be of specified upsized caliper (in addition to that identified in plant list on 6 of 19). This is to avoid any confusion or potential errors during installation (e.g. installing smaller caliper trees purposefully or accidentally). Response: Note added Comment Number: 17 Comment Originated: 06/14/2017 06/14/2017: For the green screen plantings of Hydrangea anomala petiolaris (climbing hydrangea), upsize to 5 gallon containers to be planted to give the screens more of a jumpstart in the short term, as they will take several years to establish. Choice of climbing hydrangea for green screens seems sound with high potential for long-term success as they can tolerate shade and grow up to 30 to 50 feet. Thinking ahead ensure longterm irrigation plans for the green screens are sound as well. Response: Green screen material is eliminated Topic: Lighting Plan Comment Number: 18 Comment Originated: 06/14/2017 06/14/2017: Thank you for clear identification on lighting plans of luminaires to 4 be ordered and installed and specifically those that support City of Fort Collins Dark Skies efforts in using warmer color lights (3000K or less CCT) and limiting amount of blue light in the night skies. Response: Ok. (Assuming item closed) Department: Forestry Contact: Molly Roche, , mroche@fcgov.com Topic: Landscape Plans Comment Number: 5 Comment Originated: 03/09/2017 6/12/2017: Continued: Thank you for stating that you can provide a cross-section of Tree #1. Please submit this to Forestry for review. In regards to Tree #3, please provide additional detailed information as to why this tree cannot be retained. Submit to Forestry and Project Planner for review. Response: Tree section will be provided at FDP Response: Elizabeth Street cross sections are shown on Sheet 13 of the Utility Plan Set with this submittal. 03/09/2017: Please provide a cross-section of the two existing Linden trees in regards to the proposed wall. Forestry would like to further review the distance between the trees and the structure. Additionally, please provide additional information regarding the preservation and protection of the two linden trees, and to what measures construction will impact roots. What is the foundation material for the walls? Please explore using pylon spanning to limit excavation near tree roots. Comment Number: 6 Comment Originated: 03/09/2017 Continued: Thank you for stating that you can provide a cross-section of Tree #1. Please submit this to Forestry for review. In regards to Tree #3, please provide additional detailed information as to why this tree cannot be retained. Submit to Forestry and Project Planner for review. Response: Tree section will be provided at FDP 03/09/2017: Currently, the plans show the wall proposed at approximately 3 feet away from the east tree, and 4 feet away from the west tree. With the goal of doing everything in our power to preserve the trees in mind, I recall that Sam Coutts, Jason Holland, Ralph Zentz, and Molly Roche discussed providing additional separation by shifting the walls further away from the trees, or even eliminating the walls completely. As discussed at our most recent site-visit, please provide Forestry with a detailed cross-section sketch of each tree-to-wall separation. We would also like to understand the degree of excavation involved on each side of the trees. (Email sent to Sam Coutts 3/8/17) Forestry received an email from the applicant on March 8, 2017 explaining where some adjustments had been made to help protect these trees. After 5 reviewing this communication and diagrams, there are still additional questions Forestry would like explored and answered by the applicant. Can the east wall by the west tree be adjusted further to the east to provide additional separation? Also, please explore removing the south wall by the west tree (similar to the removal of the wall by the east tree). Comment Number: 7 Comment Originated: 03/09/2017 Continued: Provide a detail of sidewalk and street trees and specify tree type and grate. Please set up a meeting with City Water Utilities, City Planner, Forestry, Environmental Planning, and the applicant to discuss having street trees along West Elizabeth. Response: Tree grate detail will be provided at FDP 03/09/2017: Per discussion with City Water Utilities (Heather McDowell) and City Planner (Jason Holland), what is the status of the sewer relocation? Please explore the feasibility of adding 2-3 additional street trees along Elizabeth Street. Please use an ornamental or narrow shade tree in these new planting locations.

Comment Number: 2 Comment Originated: 12/20/2016 12/20/2016: Electric capacity fees, development fees, building site charges and system modification charges necessary to feed the site will apply to this development. Please contact me or visit the following website for an estimate of charges and fees: http://www.fcgov.com/utilities/business/builders-and-developers/plant-investmen t-development-fees Comment Number: 3 Comment Originated: 12/20/2016 12/20/2016: System modification charges will apply to remove/relocate existing electric infrastructure on the site. Due to the existing electric system that will need to be modified, modification charges will be substantial. Light and Power has primary electric lines existing running north/south through the middle of the site and along the rear property line. It appears that these lines will need to be relocated as part of this project. The relocated lines will need to be placed within a utility easement on the site. Please note that there is a 10ft minimum separation requirement with electric lines and other utility main lines. Relocation and system modifications will be at the expense of the developer/owner of the project. Please contact me to discuss. 7 Comment Number: 4 Comment Originated: 12/20/2016 12/20/2016: Commercial service information forms (C-1 forms) and a one line diagrams for the commercial meters will need to be completed and submitted to Light & Power Engineering for review.

This material detail seems out of place in the West Central Area and more of a large commercial center detail. Staff would recommend that this be changed to a masonry detail such as the buff sandstone used on campus or brick to harmonize with the adjacent buildings. Response: Color of stone wall behind metal mesh will be selected to compliment color of surrounding buildings. Comment Number: 24 Comment Originated: 06/14/2017 06/14/2017: Provide PDP level site plan details with labeling for the rooftop amenities and interior courtyards and the inclusion of rooftop landscaping and perimeter vines would satisfy the alternative compliance. Response: Rooftop plans show amenity general areas and type.

Response: Noted Comment Number: 28 Comment Originated: 06/14/2017 06/14/2017: Too many compact spaces; over 40%; basement level parking drive aisle could be reduced and more space allocated to the parking bay. Response: Compact parking stall ratio now at 39.7% of required parking for the site. Comment Number: 29 Comment Originated: 06/14/2017 06/14/2017: Show a breakdown on the site plan indicating formulas and how you arrived at the required 382 parking total. Also show the math/formula for the retail total. Response: Parking requirement breakdown included on cover page Comment Number: 30 Comment Originated: 06/14/2017 06/14/2017: Show a cross section to the Matador to the south and the Fairview apartment to the west that shows the transitional elements height relationships. Label Fairview/1409 w Elizabeth on the site plan. Response: Per our meeting on 9/20 with City staff, the images shown clearly show a step down away from Elizabeth to the south. If a section is still needed, we can include one prior to public hearing Comment Number: 31 Comment Originated: 06/14/2017 06/14/2017: Please look closely through the parking modification request and the KH demand study and fix errors such as – table shows different bed/parking for District than is described in the mod letter and then is also different in the parking demand study. 273 parking spaces required. (278 is mentioned as the “exact number” needed in the Mod. request). The KH study also needs to be updated to reflect the site plan table. Response: Parking modification is no longer been requested, we have not resubmitted parking study Comment Number: 32 Comment Originated: 06/19/2017 Both the KH study and the TOD modification request provide a lot of detail. Please provide a summary that combines the information in both documents and provides a concise bottom-line comparison and justification, such as a matrix, so that that Board can review the information. You could also add a column for a "typical" student housing development showing the common demand mitigation deducts that other projects are taking and how this compares to the Hub breakdown. Response: Parking modification is no longer been requested, we have not resubmitted parking 10 study Comment Number: 33 Comment Originated: 06/19/2017 Basement parking: Compact spaces in basement, why are they compact on the east side? Just make the drive aisle narrower. Also the parallel spaces adjacent to the perpendicular spaces along a 20’ drive aisle seems tight. Response: Parking structure configuration and ramp layout has been revised. Please see updated parking plans. Comment Number: 34 Comment Originated: 06/19/2017 Main parking area – the two parallel spaces are an issue – please make these employee or service spaces and label on the plans. Response: Parking structure configuration and ramp layout has been revised. Please see updated parking plans. Comment Number: 35 Comment Originated: 06/19/2017 Tight maneuvering into and out of the MMN parking garage does not work well. Can the ingress/egress be simplified so that few turns are required through the entrance/egress area and can more openings be provided for visibility. Response: Parking structure configuration and ramp layout has been revised. Please see updated parking plans. Please refer to civil auto-turn exhibits for reference. Comment Number: 36 Comment Originated: 06/19/2017 The revised parking garage vehicular circulation design does not work and does not meet LUC 3.2.2. This would appear to be a major issue: Three levels of parking are required to make a 180 turn at the ramp bottom and there is not nearly enough space to make this turn without cars turning into oncoming traffic, which are already making a series of tight turns as the cars enter the garage. Walls surrounding these turns appear to be solid and further hamper site distance at the turns. Pedestrians are also walking through this vehicular area from the stairwell. Response: Parking structure configuration and ramp layout has been revised. Please see updated parking plans. Please refer to civil auto-turn exhibits for reference. Comment Number: 37 Comment Originated: 06/19/2017 Bike parking in the parking garage: If these are required bike parking spaces a location that can be found closer to the main entrance that would be preferred if feasible. Response: Bike share spaces located at entrance to southern building Comment Number: 38 Comment Originated: 06/19/2017 There’s an existing retaining wall along the south parking garage PL that is labelled to be removed on the civil set. Please also label this on the site plan. Response: Retaining wall is still proposed to be removed Comment Number: 39 Comment Originated: 06/19/2017 The parking structure will need to move back off of the private drive so that a landscape bed is provided between the back of walk and the west face of the building. The standard minimum foundation planting depth is five feet per the land use code. Response: Southern multifamily building is now setback off the property line and private drive Comment Number: 40 Comment Originated: 06/19/2017 Headlights in the parking garage facing adjacent units to the south and east need to be fully screened. Plans need to clarify how this is accomplished, clarify 11 the panel insert detail and is this solid. Response: Headlights from parking structure will be screened by solid precast spandrel elements and clad on exterior to match building finishes, typical. Comment Number: 41 Comment Originated: 06/19/2017 The shadow diagrams are missing an existing offsite building to the southwest. Response: Shadow diagrams have been updated to include building. Comment Number: 42 Comment Originated: 06/19/2017 The utility plans show an off-site tree to the south that is being removed. Show this on the tree mitigation plan. Response: Tree mitigation plan has been coordinated with utility plans Response: Trees on south shown to be removed. Comment Number: 43 Comment Originated: 06/19/2017 The entire area between the parking garage and the ex. buildings to the south is being reconfigured and will essentially be a construction staging area as well. There appear to be multiple LLC’s that own both of these properties and staff has no confirmation that the proposed plans and off-site construction activities are acceptable to these parties. This is required prior to scheduling the hearing along with any other needed letter of intent from offsite owners for the project. Response: Property to south is owned by a single entity. See comment 8 response above. Comment Number: 44 Comment Originated: 06/19/2017 Since there is already a reconfiguration of this area, why not if possible place fastigiate English Oaks and Woodward Junipers on the south property line to give more instant screening in lieu of the vines. What type of footing is used here and can the footing be notched or designed so that the trees be placed essentially espalier next to the parking garage wall and at least 4¿ away from the gas line. If this does not work, then the vines are acceptable. Would recommend planting several different types of vines in case the Hydrangea has issues. Response: There is more room between building and property line on south side now, so adequate plantings have been provided Comment Number: 45 Comment Originated: 06/19/2017 Label all surrounding buildings on the site plan, Fairview and the SW building, not sure if that is also called Matador. Response: Buildings labeled Comment Number: 46 Comment Originated: 06/19/2017 Elizabeth Street -- With tree grates typically we are looking for those to be 5’ if achievable instead of 4’s. Please confirm what is shown. Response: 5’ tree grates shown Comment Number: 47 Comment Originated: 06/19/2017 Fence shown on the utility plans is offsite on the property to the south and east, is this correct? Please also show all fencing on the site plan, some is missing and show details for the fence design with the planning set. Response: Fencing is now shown only on SW side of main building, where emergency access gate occurs.

This means that the rational method calculations and spreadsheets that you have used to calculate the hydrology at the site for the 2-year and 100-year storm are required to be included in the drainage report. Response: All runoff calculations are shown within the drainage report. 03/06/2017: All runoff calculations need to be provided. Comment Number: 17 Comment Originated: 03/06/2017 03/06/2017: Page 3 Storm Sewer Design: Tc of 5 minutes should be used for all your basin calculations. Also, hydrologic calculations should be provided for the 2-year and 100-year storms. Response: Tc of 5 minutes used for all individual basin calculations. Comment Number: 18 Comment Originated: 06/09/2017 06/09/2017: For LID systems that are volume-based are sized based on the WQCV (water quality capture volume). The WQCV calculations need to be included in the drainage report. The WQCV calculation can be performed using the UDFCD spreadsheets. Note that sand filters and rain gardens are volume-based LIDs. Bio-swales are not volume-based and are sized based on the run-on area. The maximum allowable run-on for bio-swales is 10:1, meaning that the area running onto the bio-swale must be no more than 10x the area of the bottom (the bottom 2’ wide flat part only) of the swale. Please revise your calculations for the bio-swale or change the LID system in this area to something will more likely work. Response: LID systems revised to be rain gardens. Appropriate calculations shown in the drainage report and spreadsheets. Topic: General Comment Number: 7 Comment Originated: 03/06/2017 06/09/2017: Please review this comment again. The run-on ratio for bioswales is the run-on area: bio-swale bottom area (flat area only). I don’t know if you will be able to make a bio-swale work here, so I would suggest sizing this area for a rain garden or sand filter. 03/06/2017: Drainage Plan: Bioswales are required to have a minimum 2-foot wide bottom width. The run-on ratios for bioswales are based on a maximum 10 sq ft area run-on to a 1 sq ft bottom area of the swale. You will need to show the bioswales with a width to the bottom and show how the run-on ratios work. Response: Rain gardens are proposed as opposed to bioswales. Comment Number: 19 Comment Originated: 06/09/2017 06/09/2017: Drainage Plan and Storm Sewer Plan: Please note that the relocated storm line running along the eastern side of this project site is not public. This is still a private storm pipe, to be owned and maintained by this project owner. Please label all storm lines on this project (other than the storm line running along Elizabeth) as “private”. Response: Storm lines noted as “private” on storm sewer plan. Comment Number: 20 Comment Originated: 06/09/2017 06/09/2017: Drainage Plan: the sand filter located on the east side of the building will need to be sized for the WQCV. (Volume-based LID’s are sized for 13 the WQCV not for run-on ratios.) Please provide the WQCV calculations. You may utilize the UD spreadsheet for this. Response: Proposed rain gardens are sized appropriately and calculations provided in the spreadsheets in the stormwater report. Comment Number: 21 Comment Originated: 06/09/2017 06/09/2017: Grading Plan: There are permeable pavers shown on top of the water meter vaults. I don’t think this will work with the subsection that is required for the pavers. Please revise. Response: Pervious pavers no longer shown over meter vaults. Comment Number: 22 Comment Originated: 06/09/2017 06/09/2017: Storm Sewer Plan: We still have concerns about the placement of the storm pipe near or below what looks like stairs and/or walls along the building frontage on Elizabeth Street. Please provide a cross-section of what this looks like. The cross-section should accurately depict the depth of the storm pipe and the foundation of the stairs/walls. Response: Walls and stairs removed from being placed over existing storm sewer.

Department: Traffic Operation Contact: Nicole Hahn, 970-221-6820, nhahn@fcgov.com Topic: Traffic Impact Study Comment Number: 1 Comment Originated: 12/20/2016 6/14/2017: On page 26 of the revised study the engineer indicates that the LOS of Elizabeth will drop to an F if the West Elizabeth plan is implemented. We would like to work with the traffic engineer to better understand the results they are finding with this implementation. At Shields and Elizabeth: The TIS shows the existing overall LOS at Shields and Elizabeth as LOS F. That would potentially invoke Adequate Public Facilities constraints through our Land Use Code and as such this should be double checked. Also, the TIS recommends removal of split phasing to improve operations. In the past this strategy was not possible/beneficial due to geometric constraints (shared through/left lanes) and pedestrian calls (on the north side crosswalk almost every cycle). The conclusions also list recommended changes to auxiliary turn lane lengths. Unless you¿re proposing to construct those, the assumptions in the study (especially in the short term) should reflect the actual turn lane lengths. Please call so we can discuss the timing, existing LOS, ped calls, and what improvements are possible or anticipated with the current underpass project that can be assumed. At Shields and Elizabeth, please include movement and approach LOS information. Any movements / approaches that do not meet LOS standards will require variance letters. Response: Traffic study revised and resubmitted. 3/8/2017: As previously mentioned split phasing is not possible with the ped calls that occur at the Shields and Elizabeth intersection, please revise this in the traffic study. 12/20/2016: 12/14/2016: The traffic study has been received and reviewed. There are a few refinements needed for the next submittal.

This study identifies utilization rates but some additional information is needed to truly identify demand. How many permits are in circulation? How much do the permits cost and how many car-owning/driving tenants have opted to park in the neighborhood? What is the District’s leasing occupancy and do they know the amount of tenants who own cars?

Comment Number: 19 Comment Originated: 06/09/2017 06/09/2017: Utility Plan: Sanitary manhole S15 is located in the existing detention pond. Please include a label that indicates that a water tight lid will be required. Response: Structure S15 does not apply due to the reconfiguration of the sanitary sewer. Structure S11 has been labeled to be water tight due to its proximity to the rain garden. Comment Number: 20 Comment Originated: 06/09/2017 06/09/2017: Utility Plan: The proposed water meter sizes need to be reviewed again, as these are very oversized. The placement of the meter vaults will also need to be reviewed again. It looks like the meter vaults are sitting right next to or on top of the existing storm main. The meter vaults will need to shift south to provide adequate separation between the two utilities. In addition, the Utility Crossings table indicates that there are some tricky utility crossings in the area of the meter vaults. A profile of these utility services will need to be provided to show how they are going to be constructed. Response: Water sizes have been reviewed along with water meter vault locations and revised accordingly. Profile for proposed water line connections at Elizabeth Street provided on Sheet 13 of the Utility Plan Set. Comment Number: 21 Comment Originated: 06/09/2017 06/14/2017: Utility Plan: The proposed configuration of the sanitary sewer includes a private main (or service) that drains to the west and is located approximately 8’ north of the wall of the parking structure and on Hub property. This private main connects to a proposed public main that would be located within the private drive in between Taco Bell and Uptown Plaza and on Uptown Plaza’s property. The public sewer main would need to be placed within a dedicated utility easement and the owner of the Uptown Plaza has not been amenable to allowing this dedication of the easement to date. The applicant has asked that the City consider utilizing eminent domain to aid in acquiring the needed easement. At this time, City staff needs more time to discuss the issues presented and we cannot yet recommend proceeding to P&Z until the issues have been further considered. Response: N/A Topic: Landscape Plans Comment Number: 6 Comment Originated: 12/19/2016 06/09/2017: Tree placement along the building frontage on Elizabeth Street looks to be within 3-4’ of the storm and/or existing sewer main. These still don’t meet the City’s separation requirement between utility mains and trees. Please 18 revise. Response: Sanitary has been relocated out to Elizabeth to give room for street trees 12/19/2016: Landscape Plans: Trees are required to be located a minimum of 10¿ from utility mains. Along the front of the building the proposed trees will need to be relocated as they are in very close proximity or on top of the existing sewer and storm mains. Comment Number: 16 Comment Originated: 03/06/2017 06/09/2017: Tree placement along the building frontage on Elizabeth Street looks to be within 3-4’ of the storm and/or existing sewer main. These still don’t meet the City’s separation requirement between utility mains and trees. Please revise. 03/06/2017: The tree placement shown along the building frontage does not look like what we had discussed via email with Sam Coutts. There are two proposed trees shown to be placed between the sewer and storm line along the frontage and I thought the trees were to be placed directly adjacent to the curb in this location? Comment Number: 18 Comment Originated: 06/09/2017 06/09/2017: The proposed utilities shown on the Landscape Plans don’t match those shown in the Utility Plans. Please coordinate.
