CO 80526 303/226-4955 063-001 May 4, 1984 Mr. Jon W. Savignano NDC DEVELOPMENT COMPANY 6553 S. Dayton St. Suite #3800 Englewood, CO 80111 RE: McClelland Office Park P.U.D. Dear Jon: This storm drainage letter report and supporting calculations are submitted for the proposed McClelland Office Park P.U.D. located approxi- mately 500 feet south of Harvard Street on the east side of McClelland Drive in Fort Collins, Colorado. The site Is bordered by commercial properties to the north, east and south while facing onto McClelland Drive to the west. The site topography splits the historic flow two directions. One area flows in a southeasterly direction at a 1.2% grade. The other area in a northeasterly direction at a 1.3% grade. The existing Ground is covered with native grasses. All historic offsite flow is intercepted by McClelland Drive. DESIGN CRITERIA --------------- --------------- The two year historic flow from the site's two detention areas will be outlet to a 43" x 27" CMP on the east property line of the Executive Car Wash through an outfall pipe. The outfall pipe to this structure is sized for the two year historic flow from both the McClelland Office Park and Solar One. The majority of the procedures, methods and numerical constants were obtained from the City of Fort Collins Storm Drainage Design Criteria revised March 1984. The capacity of the piping was determined by Manning's Formula which equates a constant, a roughness factor, the area of flow, the hydraulic radius and the slope, to the capacity of the pipe. In order to restrict the outflow from each detention area, an orifice plate will be used. The proposed development consists of three, three story office build- ings and associated parking. The following is a breakdown of the proposed ground cover: Buildings 32,200 S.F. Parking, Driveways 8 Sidewalk 109,500 S.F. Landscaping 50,100 S.F. This ground cover will produce a composite runoff coefficient of 0.74 for developed conditions. It is proposed to provide stormwater detention in accordance with the guidelines stated under the Design Criteria section of this report. For a 100-year storm event, the volume of storage necessary is 32,400 cubic feet, calculations> enclosed. The ponding will occur in parking areas and will be limited to a maximum depth of 1.5 feet. - 2 - Detention will be released through area drains with orifice plates for restricting the flow, calculations attached. The flow will then go through a fifteen inch storm sewer piping system to the 43" x 23" CMP storm drain. In order to properly handle the stormwater from the buildings, the following Ml1SI occur. One; the buildings adjacent to the east property y. . line must have downspouts designed to drain to the parking areas to the west. And two; the middle building must split its drainage equally to the north and south. :# �. ". S t e"d x Yam` sv%$ oar r 2" 411 a '� q When properly constructed, this drainage plan will satisfy all hydrau- lic considerations as well as City of Fort Collins current regulations in providing the proposed development with both a safe and economic method of stormwater management. Should you or others have comments or questions concerning this drain- age plan, please contact us. Very truly yours, REID, INC. G Robert M. Mcl_au I in Takeda, P.E.

Development Company, Inc. 6565 South Dayton Street, Suite 3800 Englewood, CO 80111 Dear Mr. Lamer: The City has proceeded with amending the Development Agreement for McClelland —Office ---- Rark--R-U-11. to allow a Footing and Foundation Permit to be issued once the conditions of the amendment are met. When all City Code requirements are met, the Engineering Division will release any holds on the full Building Permit for Phase I at McClelland Office Park P.U.D. This includes but is not limited to the completion of waterlines, fire hydrants, sanitary sewer and streets serving such structure and said improvements being accepted by the City.

Additionally, I understand the building in this project addressed as 2850 McCelland Drive is in the process of changing ownership. According to the documents on file with the City this project was platted as one lot. Consequently, all structures built inconjunction with this Development are obligated to the Development Agreement. However, in discussing this issue with staff and finding that the public improvements ie., water, sewer storm sewer and etc. associated with 2838 have been installed and are complete, it is our belief that the requirements of the Development Agreement as they pertain to this building have been met. Please be informed that the fulfillment of requirements as outlined by the Development Agreement only applies to the structure addrressed as 2850 McCelland Drive. No other activity will be allowed on the remaining portions the McCelland Office Park project until the utility plans and plat have been resubmitted to the City for its' review and the necessary amendments to the Development Agreement have been made. Hopefully, I've addressed your question and if you need aditional information please call me at 221-6605. Sincerely, l \ David Stringer Chief Construction Inspector 281 North College Avenue • P.O.
