'.:�vEE ENGINEERING SERVICES DEPARTMENT December 11, 1978 David L. Oyler Melody Construction Company 11031 Sheridan Boulevard Broomfield, Colorado Dear Mr. Oyler: Following the discussion in our offices on December 1 regarding the two developments your firm is considering, I had an opportunity to review our records of these properties. I hope the following information will be helpful. In regard to the area north of the proposed Trend Homes development, I believe we discussed briefly the problems associated with storm drainage on this site. In reviewing the design information in our files for the drainage in Cedar Village Subdivision, it appears that only the 36 acres included in the first and third filings of the subdivision were considered in sizing the detention pond. In addition, the pond was sized in accordance with the City's old drainage requirements, which have now been revised. As a result, the capacity of the pond is only 1.8 acre-feet, while ny calculations for the site under the new drainage criteria indicate approximately 4.0 acre-feet of detention storage would be required. In view of this, it appears that any development of the area south of Cedar Village Subdivision must provide on -site detention of storm runoff from that development. With respect to the off -site drainage which enters this site from the Trend Homes development, the final engineering drawings are now being prepared by James Stewart and Associates, a local consultant. As the City probably will not have an opportunity to review these drawings for several weeks, it might be prudent for you to direct your questions concerning this drainage directly to the consultant. Vic Weidmann is the engineer with Stewarts who has analyzed the storm drainage. If it would be convenient, perhaps I could arrange a meeting between yourself, Mr. Weidmann, and the City's storm drainage engineer to discuss this matter in more detail. Regarding the proposed Allen Farm development, the plans for the outlet facilities are still in the preliminary stages. We are currently looking into the possible conflicts with other utility installations already located in Shields Street, and we hope to proceed with the actual design very shortly. As to the extent of your participation in this matter, I believe Mr. Bartran agreed to bear the cost of installing the line from his detention pond to the low area immediately north of Swallow Road, which is approximately one-fourth of the proposed line. This participation will not include any engineering costs as the City has accepted the responsibility for the design. Perhaps you could verify this agreement with 100% Recycled Bond M E M O R A N D U M TO: Cathy Chianese, Planning Department FROM: Marc Engemoen, Engineering Department DATE: May 3, 1979 RE: Cedar Village, Fifth Filing Regarding the proposed first phase of Cedar Village, Fifth Filing: (1) we agree that the proposed location of Swallow Road is the logical extension of that street, and that the resolution of the storm drainage situation for this area will not alter the proposed align- ment in either the first or second phase of this development; (2) we are in the process of retaining a consultant to analyze the storm drainage in this basin with respect to the City's role in providing a by-pass channel, and will not approve any plans for the second. phase of this development prior to receiving the recommendation of that consultant; (3) the first phase of this development must submit a drainage report and drawings indicating how they intend to provide on -site detention of storm run-off for this site; and (4) final approval of this development requires that the developer dedicate all necessary easements and design the necessary improve- ments to provide for the passage of historic storm waters across this site. ME/lm Z PICSOURCE COH ULTNHTS 1HC May 4, 1979 Mr. Bob Smith Engineering Services Division City of Fort Collins P. 0. Box 580 Fort Collins, CO 80522 Dear Bob: E. Brm-e o,)es, PE v%' e,t, r ,t: ,. F E a Ls .%'ci._� N x_ s, V E ? Es Gt wqt- Pl-dos D,rvid 'M Frick_, FF This letter is in response to the request you made in our meeting of May 1 concerning a hydrologic analysis of the drainageway through the Cedar Village Subdivision area. I have reviewed the information concerning the major drainage requirements for Cedar Village Fifth Filing and the Ross - borough Subdivision to Spring Creek. Based on this brief analysis, I have come up with a proposed study which would include a hydrologic analysis of the various aroblems and determine alternative solutions and cost estimates. In recent work which we have completed for James H. Stewart & Associates, Inc., we have performed hydrologic calculations for Rossborough Subdivision and have made a brief analysis of the Cedar Village Fifth Filing area. Based on this analysis it appears that this major drainage area south of Spring Creek would :include the Cedar Village Fifth Filing and Rossborough Sub- division, as well as areas to the south and west of Rossborough and areas east and west of Cedar Village Fifth Filing. Based on the information that we have developed, it would be possible to come up with design hydrographs at the north boundary of Cedar Village Fifth Filing. These design hydro - graphs can take into account the outflow from the Rossborough Subdivision, as well as the drainage from the west of Rossborough which is proposed to be diverted around the north boundary of the Rossborough Subdivision. My initial analysis utilized a drainage area into the Cedar Village Fifth Filing, which was somewhat larger than the subdivision itself, to take into account offsite drainage entering the subdivision. Therefore, based on the information I currently have, I can readily develop design hydro - graphs from these areas for the 2-year and 100-year storms. Based on the design hydrology, the next portion of the study would be to determine the various improvement alternatives and to analyze the cost of each alternative. 1. One alternative would be to not provide any drainage facilities and to allow the drainage to proceed overland through the current Cedar Village Post Office Box Q • Fort Collins, Colorado 80522 • (303) 482-8471 Denver Nlietro (303) 572-1806 Mr. Bob Smith May 4, 1979 Page 2 i development. These flow figures could be utilized in developing a damage estimate for benefit -cost studies. 2. A second alternative would be to create a pond on the Cedar Village Fifth Filing for detention of storm water directly from that area. This alternative would consider carrying all drainage water from Rossborough Subdivision and areas south and west of Rossborough along the west side of Cedar Village Fifth Filing. This would produce similar results to your current analysis of the major drainageway and conduit on the west side of the Cedar Village Subdivision. 3. Another alternative would be to analyze the use of the Cedar Village Fifth Filing detention pond for onsite drainage and also to route some overflow from Rossborough Subdivision through this pond and i, down Hanover Street or through a storm sewer under Hanover Street. The remainder of the flows for this alternative would be carried down a smaller open channel on the west side of the Cedar Village Subdivision. 4. A fourth alternative would be to take all of the flows to a concen- tration point: near Hanover Street routing some portions of these flows through a detention basin and releasing the major part of the flows down Hanover Street in a manner which would create little or no damage during the major storm. / Based on &ese various alternatives and any additional alternatives that might be determined during the course of the study, we could then make preliminary cost estimates for these various improvements. At this point in the studies I would submit to you a letter outlining the results of our studies and containing cost information for various improvement alternatives. Some of these improvement alternatives might not eliminate total damage during the 100-year flood; therefore you would have design flows that you could use to make a benefit analysis for various improvement alternatives and to determine benefit -cost ratios for each alternative. From the resulting cost estimates and the benefit analysis that you could prepare, a decision could be reaches as to the most appropriate improvement alternative. I would estimate that the cost of our portion of this study, based on information we have and the information your office has developed, would be somewhere between $1,000 and $1,500, depending upon the number of improve- ments analyzed and the complexity of the various improvements. I would also estimate that we could complete this study in 3 to 5 weeks after approval of this proposal. Mr. Bob Smith May 4, 1979 Page 3 I hope this presents the information you have requested. If you have any further questions concerning our proposed study, please let me know. Sincerely yours, RESOURSE CONSULTANTS, INC. a�'z t�"- David M. Frick DMF:km MILLER PROPERTIESINC. 11.0.

Filing, to protect the lo:s adjacent to Trend Homes' Property. Miller Properties, Inc. Bruce E. Miller BEM/gmf August 23, 1979 TO: H. R. Phillips, Director of Parks & Recreation FROM: Bob Smith, Storm Drainage Engineer/1-14RE: Detention Pond, Rossborough Subdivision This letter is to inform you as to the status of the drainage problems between the Rossborough (Trend) and Cedar Village 5th subdivisions. You are probably aware that during the discussions it was proposed to separate the detention pond from the park site in the Rossborough subdivision and combine it with the pond in the Cedar Village 5th subdivision. To do so would have involved a considerable time delay for the developers with regard to replatting the property and answering the ccu Alex problem of who actually benefitted by the revisions and who was eligible for additional ccn pensation. The developers felt that they could not accept the time delay and it was finally decided that the Rossborough developers would develcp with the understanding that they would have their original combination detention pond and park site located in the N.E. corner of their subdivision. Also, the Cedar Village subdivision would accept the runoff from the Rossborough site and they would handle their own drainage in a separate detention pond. If I can be of any further assistance on the matter, please feel free to contact me. (_I I YM I OR I (O11-INS P.O.

Box 580 Fort Collins, Colorado 80522 Re: Cedar Village, Fifth Filing Dear Mr. Rupel: We are the developer and builder of the suject subdivision at Cedar Village, Fifth Filing and are applying for subdivision approval through the Veterans Administration. One of the standard VA and FHA requirements is that we obtain a letter from the local authority regarding the acceptance of the streets. The letter should indicate their willingness to assume responsibility for maintenance of the streets, drainage structures and sewer and water facilities as soon as the developer has ful- filled his obligations. May we have such a letter addressed to the Veterans Administration but s-nt to our address sn that it may be included v.1ith the other documents and exhibits that we will file with the VA. Thank you. Sincerely, , C-J Associates 5'--J rft Venture d. Jensen Enterprises, Inc., Partner Dan R. Jensen, President DRJ/ss David L.
