Box 580 Fort Collins, Colorado 80522 Attention: Mr. Robert Sinith, Assistant Engineer Re: Detention Requirement variance for Park Central P.U.D. Dear Mr. Smith: A variance from the requirement of the City of Fort Collins "Stcrm Drainage Design Criteria", dated January, 1980, for on -site detention is recuested for Park Central P.U.D. No on -site detention is proposed for this project for the followinq reasons: the improvements rude to Spring Creek are based on the 100- year fully developed flows; the time of concentration when Park Cen- tral F.U.D. is contributing its maximum 100-year flow into Sprirg Creek is 15 ininutes into tie storm; the peak flow from the Sprirg Creek hydrograph does not occur until approximately 2.5 hours irto the 100-year storm. It is our conclusion that the flows released directly into Spring Crnrl< `rnni pare (Pniral P,:1 F) kill not cinrifirantl­ inrrFa�n 1hr downstreali, flood peak; therefore, no detention is proposed. if you have any questions, comments, or need additional information, please advise.

Collins, Collins Center Ave. CO 80521 June 4, 1985 Re: Park Central P.U.D. Job No. 10-252-103 Two structures will be constructed near Spring Creek within the area designated as the Park Central P.U.D. Phase IV. The struc- tures will be constructed entirely or in part, within the area inundated by the 100 year flood. The structures will be ele- vated 18" above the 100 year flood and will not increase the base flood level to the detriment of property along Spring Creek. All applicable requirements will be followed during their final design and construction. The structure to be constructed within Phase III is not located within floodplain limits. Flood peaks, volumes, and discharge points will not be signif- icantly changed from the original estimates. Construction will require the relocation of a detention area and existing swale. The design and location of these hydraulic structures will be submitted in the final (revised) drainage report for this area. 7sin.eWreil, Roger Peterson, P.E.

L City of Fort Collins October 4, 1988 Mr. William Albrecht President, Albrecht homes 4836 South Collcgc Avenue Fort Collins, CO. 80525 Dear Mr. Albrecht: As you are probably aware, the Alcdical Center of Fort Collins P.U.D. at the northeast corner of Prospect Road and Lcill ny Avcnuc received preliminary approval from Cu Cite o[ I ort Collins Planning and Zoning Roard on August 22, 1988. Final P.U.D. approval will be considered by the Planning and "Zoning Board at the public hearing scheduled for October 24, 1988. As part of the requirement for redeveloping the old gas station site on the corner, the applicant must fully improve the curb, guttcr and sidewalk on both Prospect Road and Lcmay Avenue. The applicant has indicated a willingness to fulfill this obligation. As part of the Development Agreement for the Par k_Central P.U_D., the organiza- tion owning Park Central P.U.D. is responsible for constructing a right turn bay on westbound Prospect Road for turning onto northbound Lemay Avenue. This right turn bay construction consists of the full pavement section as well as a transitional "taper" but would not include the curb and gutter. 'File Planning Department feels the public would be best served if the two obliga- tions of the Medical Center and Park Central would be coordinated as one pro- ject. By coordinating bath obligations, the construction time would be reduced and the inconvenience to motorists would he minimized. The Planning Department also feels it would be in the interest of the Park Central V.U.D. ownership to coordinate the project rather than act separately at a later date. It will eventually be a greater expense to the Park Central P.U.D. ownership to have to demolish the Mcdical Center improvements in order to provide the right turn bay. This added demolition cost would be unnecessary if the two public obligations were coordinated into a joint project. The Planning Department strongly urges you, as representative of the Park Central P.U.D. ownership, to obtain a cost estimate of the right turn bay pavement section and to consider coordinating the construction with the Medical Center of Fort Collins. The obvious benefit to Park Central P.U.D. is to save on 300 LaPorte Avenue • P.O. Boy ;SO • Fort Collins, CO 80522-0580 • (303) 22t 6750 future demolition costs. The benefit to the City is to. minimize lane closures at the intersection of tN%o arterials within one half mile of the Poudre Valley Hospital. Please Cccl free to ca� the Planning Department if you have any questions or need clarif icaticn on ny engineering details. We will be glad to assist in any way possible.

Diehl Cornell Consulting Ccaripany P.O. Box 646 Ft. Collins, CO 80522 Dear Mr. Diehl, 580, Fort Collins, Colorado 80522 In reference to your request for a variance in the detention requirements for Park Central P.U.D., I have the following coranents. The reasoning behind your request is correct in that the difference in the tine to peak between Spring Creek and the site is indeed large. The 100-year cL�veloped runoff peak from the site should be sufficiently ahead of the Spring Creek peak to pose no problems downstream. Your request for a variance in the detention requirements is hereby granted provided your design incorporates sufficient erosion control and adequate structures to channel the sites runoff into Spring Creek.

Mountain Ave. Fort Collins, Colorado 80521 RE: Spring Creek Trail Easement Dear Frank: This letter is to inform you that we will comply with the City's request not to include an easement on the plat for the proposed Spring Creek Trail located on Park Central D.U.D. Phase 1. Their intent is to establish the easement after the trail is constructed. This does not appear to create any problems with the engineering design completed to date. However, it is important that the location of the trail remain in the position that we have determined. If the trail were to be moved, it would alter the designed capacity of the proposed Spring Creek channel. This would mean a reevaluation of the channel configuration. 4Je recommend that a statement in the subdivision agreement be included that would fix the position of the trail to the present designed location. If you have any questions, comments, or need additional information, please advise us.

In going; over the existing utilities, it appears that the 6" water line will not have the required 4 1/2' of cover required, thus it will be necessary to insulate the pipe with some type of "blown -on" insulation. This revision to the original plans must be shown on the record drawings provided the City's construction inspectors when the project is completed. Sincerely, Webb Jones Systems Engineer cc: Bruce Fisher Rodney Albers Bonnie Tripoli MEMORANDUM To: Joe Fry, ZVFK Architects From: Bob Shemmerling, TST Engineers' Date: January 25, 1984 Subject: Park Central P.U.D. Phase I Job Number: 83-293-003 Last week we investigated eliminating the proposed water line in Park Central P.U.D. Phase I as shown on Cornell's Construction Drawing and the proposed Water Line in Phase II adjacent to tract's D & E. Several City agencies were contacted to obtain their approval including: - Water and Sewer Department (Web Jones) - Planning ----------------- (Bonnie Tripoli) - Fire Department ---------- (Mark Springer) - Engineering -------------- (Dave Stringer) We requested eliminating this Line because of the following reasons: 1) The Health Club is intended to be sprinkled and the fire hydrant to be installed in front of the Club can provide adequate flows from the 12-inch main in Prospect Rd. 2) We found that current hydrant spacing met City standards and therefore, this loop was not technically necessary for fire protection. 3) Construction costs could be reduced. Eliminating this Line was approved by all the above depart- ments based on the following conditions: 1) Only one curb cut be made into Prospect Road as shown on Cornell's drawings. 2) The fire hydrant constructed at the southwest corner of Tract D be reconstructed so that the fare hydrant is tapped off of the 6-inch Line in the Phase II drive from Prospect Road. In addition, the existing Line to this hydrant is to be removed back to the 6x6 tee juncture where the main goes west from the Phase II drive and this tee is to be plugged and blocked on its east end. Page Two Memo To Joe Fry ZVFK Architects From Bob Shemmerling January 25, 1984 These provisions will be shown on Engineering Drawing Revisions to'be prepared by our office -and will be submitted with the revised Health Club Site Plan being prepared by ZVFK Architects. I informed Steve White, Park Central Project Manager for Osprey, Inc., by meeting with him at his office of these events. He expressed no objections to this plan and instructed me to proceed with the revisions. An added bonus achieved using this Plan was that a Footing and Foundation Permit was released by the City of Fort Collins so the Building Construction could commence. The final Building Permit will not be released until the revised drawings are approved by the City of Fort Collins.

I Job No.: 83-294-000 Attn: Phil Waite, Engineering Division Dear Phil: Our office has submitted a revised grading plan for Park Central Phase I. To make this plan work a storm drain system is required. Please refer to the construction plans. The storm. drain system is designed to collect and transfer the 100-year developed flaws frcrl the shown inlet collection points. The expected I00-year and 2-year flood rates are shown on the storm sewer plan. No on -site detention. will be created by the addition of this system. It noshx en added _ontx as _a_iear ___of _ Qy7 ring the _ avenge itecr-i.des so imported fall can be mrmn.izLci. As you can see, the construction of this line will. eliminate the tem orary drainage Swale shown on the Phase II drawing that flows across Tract E. This is in conformance with the Phase II drainage study. All future construction. in Tracts P oral E will be designed to utilize this storm drain system.

April 26, 1985 Red/ Park Central Floodway 1 kevision _ Job No. 1 for Spring Creek between Lemay Avenue reach adjacent to and downstream of One of the runs (100 yr. Q = 3,300 cfs) is a reasonable replication of the Federal Emergency Management Agency, Flood Insurance Study (revised February 15, 1934). The second run uses a design flora of 5,000 cfs, as reccarr,tended in the Spring Creek Major Drainageway Plan, by Gingery Associates, Inc., dated August, 1980. This run provides a high water elevation of 4,939.27 to be used for design. The corresponding minimum finished floor elevation would be 4,939.8, but for additional safeguarding, the minimum finished floor elevation should equal the existing building (4940.2). This, of course, does not include the volleyball court, pool equip ent enclosure, landscaping and fencing. Also enclosed is a drawing showing the location of the FEMA cross -sections, project cross -sections and the floodway defined by the = Floodway map.
