SPR 10 IS90 BOOK 79 PAGE 875 5 NORTH COUNTY DISTRIBUTION SYSTEM WATER MAIN EXTENSIONS The Board reviewed the following memo: DATE: MARCH 30, .1990 TO: JAMES E. CHANDLER COUNTY ADMINISTRATOR FROM: TERRANCE G. PINXOi DIRECTOR OF UTILITY SERVICES PREPARED JOHN F. LANG AND STAFFED ENVIRONMENTAL PECIALIST BY: DEPARTMENT OF UTILITY SERVICES SUBJECT: NORTH COUNTY DISTRIBUTION SYSTEM WATER MAIN EXTENSIONS BACKGROUND ` The Department of Utility Services has a number of franchise and purchased water treatment plants north of 65th Street, in addition to the privately operated facilities. The South County Water Treatment Plant Expansion Project (UW -89 -07 -WC) will provide excess capacity initially for the South Region. The Department proposes a water main extension in three phases to link these small package facilities together and then to eliminate them in the North Region. The plants to be affected are: Sandridge Golf Course KOA Hobart Park Park Place Wabasso School New Horizons Breezy Village Aspen Whispering Palms I & II Pelican Pointe GDU Pipeline to River Run, Reflections on the River Phase I construction would link the Breezy Village, Park Place, and Pelican Pointe Water Treatment Plants with an estimated cost of $350,000.00. Phase II construction would start at 65th Street and 58th Avenue, proceed north to S.R. 510, east to U.S. #1, and then north and connect to Phase I. Phase II has been estimated at $1,1007000.00. Phase III construction would start at north termination of Phase I and proceed north on both sides of U.S. #1 to Schumann Drive and River Run respectively. The estimated costs associated with Phase III are $800,000.00. A fourth phase to be constructed in conjunction with the North County Water Treatment Plant would consist of constructing water mains on U.S. #1 east right-of-way from S.R. 510, south to connect at 49th Street. ANALYSIS All water mains in the four phases would consist of master plan ;` sized mains. The linking of the Breezy Village, Park Place, and .Pelican Pointe Water Treatment Plants would eliminate the possibility of water outages due to plant failures. The Phase II ..and III constructions would place large mains in right-of-ways prior to additional development, as well as to allow elimination of the listed package plants. Phase I financing would be from impact fees on an interim basis ultimately to be included in a bond issue to finance Phase I through IV and a North County R.O. Plant. RECOMMENDATION The Department of Utility Services recommends that the Board of County Commissioners conceptually approve the North County Distribution System Water Main Extension Project and authorize negotiations with engineering firms for design of Phases I.- III. 86
