. . . Memorandum July 2, 2002 Page 2 The project also includes the replacement of approximately 1300 feet of8 inch diameterwatermain located along Old Highway 10 between Lake Valentine Road and County Road E-2. The new watermain will be plastic in lieu of cast iron and should not cxperience the same degradation that thc cast iron has experienced in this part of the City. The project includes directional boring of the watermain across Lake Valentine Road and County Road E-2 to minimize disruption to the travelling public. The project also includes a water service to Valentine Park for potential future fountains and restrooms. The watermain is locatcd parallel to and approximately 10 feet apart from an existing 12" and 10" diameter sanitary sewer trunk main. The sanitary sewer trunk main was televised several years ago and consists of clay pipe in fair to poor condition. The project includes the lining of the sanitary sewer adjacent to the watermain in order to protect the sanitary sewer from damage during the replacement of the watermain (adjacent excavation), and to extend the life of the pipe by at least fifty years and greatly reduce infiltration of groundwater into the system. The Engineer's Estimate for this portion of work is $155,000. The total estimated construction cost for the 2002 Sanitary Sewer and Watermain Improvements is $255,000. There was no planned budget for this rehabilitation work. The Sewer Utility Fund #602 currently has a balance of approximately $1,650,000. The Water Utility Fund #601 currently has a balancc of$I,500,000. 2002 Drainaee Improvements The project includes improvements at Perry Park along an existing slope to address a severe erosion condition which may ultimately threaten playing ficlds.
