The project is currently in the Preliminary Development Plan process and currently one (1) variance is being requested to modify portions of the Fort Collins Stormwater Criteria Manual as follows: VARIANCE REQUEST –STORMWATER DETENTION STANDARDS DESIGN CRITERIA OF VARIANCE BEING REQUESTED Section 6.0 within the Fort Collins Stormwater Criteria Manual which states: Onsite detention is required for all development projects. The required minimum detention volume and maximum release rate(s) for the developed condition 100-year recurrence interval storm must be determined in accordance with the conditions and regulations established in the appropriate Master Drainage Plan(s) for that area of the City, for the development and in accordance with the criteria set forth in this Manual. HARDSHIP REGARDING REQUIREMENT The site is located at 1600 East Prospect Road within Prospect Park East P.U.D and is surrounded by existing fully developed commercial properties to the south (Advanced Energy) and west (Larimer County Coroner) along with Prospect Road and Sharp Point to the north and east respectively. The original subdivision development planned for drainage to be conveyed via overland flow to the drainage facility located south of the site; therefore, no storm sewer currently exists on the site. However, the original subdivision plat did not include drainage easements on the property to allow for the conveyance of 100-year stormwater runoff from the site, across the property to the south and to the existing drainage facility. After discussion with the south property owner and their attorney, the southern property owner has denied any new easements on their property. Refer to Appendix A for an email from the south property owner regarding the denial of new easements. Therefore, the site cannot utilize the detention system within the subdivision. Storm sewer for the project, required to convey both water quality and 100-year developed stormwater flows, is proposed to convey runoff to the east across Sharp Point to the existing property also owned by the developer of the Prospect Sports Club facility to avoid the need for drainage easements south of the site. PROPOSED ALTERNATE DESIGN The existing subdivision detention facility located south of the project site drains to the existing pond located east of Sharp Point prior to being released to the Poudre River. Coincidentally, the property east of Sharp Point where this existing pond is located is also owned by the developer of the Prospect Sports project. As such, the development team proposes to drain 100-year undetained flows from the Prospect Sports site directly to this existing pond, bypassing the subdivision detention facility and negating the need for drainage easements on properties south of the development site. The following sections of this variance request documents the negligible impacts this alternate design will cause the downstream pond and property. S TORMWATER V ARIANCE R EQUEST P ROSPECT S PORTS C LUB F ORT C OLLINS ,CO 19 OLD TOWN SQUARE #238 | FORT COLLINS, CO 80524 | 970-530-4044 | www.unitedcivil.com The existing detention facility was analyzed in the approved drainage report entitled, “Final Drainage and Erosion Control Plan – Advanced Energy Buildings 7 & 8”, by Park Engineering Consultants and dated June 11, 1999, see Appendix A for excerpts. In said report, the detention facility was found to require a total volume of 8.94 ac-ft; however, the facility only has a volume of 7.69 ac-ft to the centerline of Sharp Point prior to overtopping, by approximately 0.32-feet, and draining directly to the existing pond east of Sharp Point. With this request, it is calculated that the proposed development would account for approximately 0.43 ac-ft of the required volume in the existing detention facility. By piping the undetained 100-year flows from the proposed development directly to the existing pond east of Sharp Point: 1.The existing detention storage deficit in the facility to the south is reduced. 2.The amount of flow overtopping of Sharp Point is reduced. 3.The net volume of undetained storage the existing pond east of Sharp Point remains the same. Additionally, it should be noted that the existing pond east of Sharp Point is approximately 6.1-acres in size. With the required detention volume of the site of 0.43 ac-ft being attenuated within the existing pond, rather than detained onsite, the rise in depth in the existing pond would be less than 1-inch. Based on the information provided for this detention variance request, it is the design teams opinion that the proposed design will improve the function of downstream infrastructure (i.e. the existing detention facility to the south and the overtopping of Sharp Point), will have negligible impacts to the existing pond east of Sharp Point and will have no negative impacts on City infrastructure, downstream properties or the safety of the public. On behalf of the owners of the Prospect Sports Club and the design team, we thank you for the consideration of this request.

I believe there is currently an easement in place that allows access off Sharp Point Drive through our existing drive lane to your proposed site. We are not interested in entering into a parking share agreement or providing additional easements. Please note that our tenant (Advanced Energy) does not have the authority to enter into any arrangement. Please call me if you would like to discuss further – 804.357.1852.

Erika Ashauer, ALEP | Project Coordinator Direct: (970) 488-3870 From: Erika Ashauer <eashauer@rbbarchitects.com> Sent: Wednesday, December 14, 2022 3:42 PM To:jnielsen@capitalsquare1031.com Cc: 2204 Prospect East <2204ProspectEast@rbbarchitects.com> Subject: 1600 E. Prospect Road Hi Jerad, I am part of the architectural team at RB+B Architects working on the Prospect Sports facility being developed in Prospect Park East PUD, Lot 5. I will be the liaison between the Prospect Sports owner and our team, and the adjacent property owners. Have you been able to locate any existing access agreements between your property (Advanced Energy) and ours? I have not yet found any existing agreements in public records. If there are no existing agreements, we would like to submit the following for your consideration: 1.Access Easement: We would like to share the same drive used to access the Advanced Energy buildings off of Sharp Point Drive as the main point of entry to our site 2.Emergency Access Easement: Our site is relatively small, and we have determined that the fire department cannot access our lot off Prospect Rd. and will need access on the southern side of the site. The emergency access would impact the AE site by extending the lane to the eastern portion of the property so the fire lane can wrap around our property to the East. This would cause a loss of a few parking spaces and trees on your property. 3.Parking Share Easement: Since our lot is relatively small for the proposed building of approximately 35,000 square feet, we are limited to the number of parking spaces on our lot. We are currently planning on 49 parking spaces on our property. The City of Fort Collins routinely allows for parking share agreements between adjacent properties so that adequate parking is available while not creating an abundance of hardscaped areas dedicated to parking. Prospect Sports is expected to experience high vehicular parking during off-business hours: the evenings and weekends. We hope that patrons of Prospect Sports could use the AE parking lot as overflow parking during these peak times and the Prospect Sports parking would be available for AE use as well. I have attached a site plan with the proposed easements diagramed. Please do not hesitate to reach out to me should you want to discuss further.
