Assistant City Manager/City Engineer City of Coppell Post Office Box 478 Coppell, Texas 75019 Water Distribution System Master Plan Analysis Dear Mr. Griffin: In accordance with your requested, we are pleased to submit our engineering services proposal for updating the City' s Water Distribution System Master Plan, and performing a computerized hydraulic evaluation of both the master plan water distributions system and the existing water distribution system. The computer analysis will be completed utilizing the Cybernet water distribution system software which provides a graphic interface through AutoCAD 12. The focus of this analysis is to determine what, if any, water distribution system improvements are required to support the construction of the proposed 2.0 million gallon elevated storage tank in the vicinity of Thweat Road and Royal Lane and to re-evaluate the recommendations contained in the City' s current water distribution system master plan in light of anticipated land use changes in the northern and western portions of Coppell. The scope of engineering services included in this proposal are more fully described on the enclosure marked "Exhibit A". The scope of services represents a limited evaluation of the City's water distribution system based on the hydraulic data sets provided by the City. Our findings and specific recommendations will be presented in a brief letter report and is expected to include color exhibits. We propose to be compensation for engineering services on this project on actual salary cost times a multiplier of 2.3, with expenses at actual invoice amount times 1.10. We recommend the City budget an amount not to exceed $3,000 for our work on this project. This project budget amount includes our services, printing, delivery of the letter reports and maps and training on the use of the hydraulic model. Of course, if required, we are pleased to participate in any presentations to the City Management or City Council. Mr. K~nneth M. Griffin, P.E. City of Coppell 5/16/96 ' Page No. 2 If you are in agreement with this proposal for engineering services, please have one copy of this letter agreement executed on behalf of the City of Coppell and returned to our office. We very much appreciate the opportunity to provide the City of Coppell with this proposal for engineering services and look forward to working with you and the City of Coppell on this important project.

Sincerely r Enclosure APPROVED FOR THE CITY OF COPPELL By: ~ Date:/~~2~_9 ~ "' ~ Shimek ,]acobs & Finklea Exhibit "A" City of Coppell Water System Master Plan Update & Report Scope of Services I. Convert the City's current water distribution system hydraulic model KY Pipe data set to the Cybernet hydraulic model, including both existing system and build-out scenario models. II. Evaluate both the maximum hourly and minimum hourly system demands based on: A. Information contained in the current master plan report dated March, 1994. B. Available water records provided by the City. C. Current population estimates and projections provided by the City. III. Update both the existing system model and the master plan model with the revised system demands as required. This includes any special use demands as identified by the City. Apply the system demands to the hydraulic model based on existing and projected land use assumptions. IV. Model all existing pump stations utilizing actual pump flow data or pump curves, where available from the City. V. Add existing water lines to the model at the City's direction and as required to properly evaluate both the existing and build-out scenarios. VI. Evaluate and make recommendations for system improvements for both the existing system and the master plan. System improvements include water distribution lines, elevated storage tanks, ground storage tanks, and pump stations. The existing system recommended improvements shall be based on meeting the anticipated demands in the western portion of Coppell and those required to support the construction of the proposed elevated storage tank. The master system improvements will be based on the findings and recommendations of the existing system and the impact those recommendations have on the master plan. We understand the City would like us to specifically evaluate the need for distribution system improvements along the Sandy Lake Road corridor. VII. Prepare and deliver a brief letter report on water system master plan report including methodology of the analysis, recommendations, schedules, probable cost for system improvements, and if requested, computer analysis input and output data set printouts. VIII. Deliver AutoCAD drawing files of both the existing and master plan water distribution systems containing the Cybernet data base attributes. The electronic files will be delivered under the following conditions: A. The files are compatible with AutoCAD 12 by Autodesk, and Cybernet Version. 2.14 by Haestad Methods. We do not make any warranty as to the compatibility of these files beyond the release of AutoCAD 12 or Cybernet Version. 2.14.
