Box 580 Fort Collins, Colorado 80522 RE: STORM DRAINAGE REPAY AGREEMENT ON 1990 JUNIOR HIGH SCHOOL Dear Susan: This letter is a follow-up to the meeting held March 15th with City staff and George Galida (Poudre R-1), Carr Bieker (ZVFK) and Stan Myers (RBD, Inc.). This meeting was held to discuss among other subjects the potential of a repay agreement between the City and the School District for the additional costs incurred by the District to accommodate 100 year developed flows through the 1990 Junior High site. These developed flows will be channeled through the site in a series of pipes and swale sections which will run adjacent and parallel to the northerly row line of Seneca Street. The repay agreement discussed would cover the additional cost in- curred to accommodate 100 year developed versus 100 year historic offsite flows. The Final Drainage Report for Poudre R-1 Elemen- tary School dated April 1987 by EPI calculated these flows to be 226.1 cfs and 52.4 cfs respectively. Onsite developed flows will raise both these figures slightly for the culvert designs required. A preliminary hydraulic analysis has shown the 100 year developed flows will require 2-42 inch RCP when 100 historic flows can be accommodated in one 36 inch RCP. As per your request I have summarized the potential cost differential for storm drain piping and headwalls below. Other Offices: Vail, Colorado 303/476-6340 • Colorado Springs, Colorado 303/574-3504 For 100 Developed Flows: 42 inch RCP (2 lengths) 800 L.F. @ $57/LF = $45,600 4 Headwalls @ $1068 Each = $ 4,272 TOTAL $49,872 For 100 Historic Flows 36 inch RCP (1 length) 400 LF @ $40/LF = $16,000 4 Headwalls @ $613 Each = $ 2,452 TOTAL $18,452 The difference of these two totals ($31,420.00) is the ap- proximate potential cost covered by a repay agreement. This cost does not include grading or engineering costs and is dependent on the final design approach. I trust this letter addresses the concerns discussed in our forementioned meeting. Please contact me if I can be of further assistance. Sincerely, RBD, Inc. Stan A. Myers, P.E. cc: Carr Bieker - ZVFK George Galida - Poudre R-1 021-009 r UTILITIES § 26.546 basin reimbursement, prior to final approval of the development agreement the developer must submit to the stormwater utility a report detail- ing the proposed basin improvements and obtain the city's approval of the report. The report must identify all elements of the project eligible for reimbursement and include a detailed project de- scription, a project bid form with estimated quan- tities, unit prices, engineering design and construc- tion management costs. The report must also pro- vide an accurate quantity and cost delineation between the proposed basin improvements and the stormwater improvements necessary to meet the standard requirements of the development. The stormwater basin reimbursement must be taken first as credit toward the total basin fees due for the developed property with regard to which the basin improvements are being constructed and any remaining reimbursement to be paid in cash to the developer will be made as a cash repayment subject to (e) of this Section. If more than two (2) years elapse from the approval date of the development agreement without substan- tial progress toward the construction of all im- provements eligible for basin reimbursement, the reimbursement obligation shall terminate. The developer may request and the Director of Utility Services may approve extensions of the obliga- tion for additional one-year periods. (b) After final approval of the plat, the owner of the developed property shall have the option of reducing the stormwater basin fee due for the development by an amount equal to one-half (1/2) of the estimated basin reimbursement as shown in the development agreement or the total basin fees due, whichever is less. (c) Subject to the provisions of (e) of this Sec- tion, the city will make additional basin reim- bursement upon completion of all required storm - water improvements, approval by the stormwater utility and submittal by the developer of copies of the following: (1) Completed bid forms from at least three (3) qualified contractors showing which contrac- tor was awarded the project; (2) The contractor's invoice for final payment as approved by the developer's engineer separating the quantities and costs of the basin improvements from the improvements necessary to meet the standard requirements of the development; (3) An invoice from the developer's engineer clearly showing any fees charged for that portion of the work which is eligible for basin reimbursement; (4) Letters from the contractor and the engi- neer certifying that final payment has been received for the work eligible for basin reimbursement; (6) Any other information deemed necessary by the Director of Utility Services or re- quired by the development agreement. (d) The books and records of the developer re- lating to the stormwater facilities for which the utility is providing basin reimbursement shall be open to the city at all reasonable times for the purpose of audit and/or verification of costs. (e) If the estimated cost of improvements eligi- ble for basin reimbursement for a development exceeds the stormwater basin fees due for the development, the Director of Utility Services will recommend inclusion of such costs in the next available budget submittal to the City Council. Upon approval and appropriation by the City Coun- cil, such costs will be reimbursed from the storm drainage fund. (Code 1972, § 93-11; Ord. No. 161, 1986, § 2, 11-4-86) 1797 Sec. 26-546. Assessment for off -site stormwater improvements. (a) When any developer constructs stormwater facilities on or through undeveloped areas to serve the property or to meet the requirements for developing the property the entire cost of such facilities if they are not identified as an element of a basin master plan shall be the responsibility of such developer. If the facility is identified in a basin master plan, but only a portion of the cost is eligible for basin reimbursement from the storm drainage fund, the balance of the cost is the re- sponsibility of that developer. However, if the de- veloper enters into a repayment agreement with the city within ninety (90) days of the completion and approval by the stormwater utility of such 0 • UTILITIES ities will be constructed and installed as indicated and approved.

(a) If the stormwater utility requires a devel- oper to construct stormwater facilities that serve more than that development and are identified in a basin master plan, a portion of the actual costs incurred may be eligible for basin reimbursement from the storm drainage fund.
