Capital Improvement Project


Cobblestone Dr Zone R2-R4 Water Main Connection

Estimated Construction Schedule: Slated to begin August, 2019 and is anticipated to be completed July, 2020.
Construction Contract Amount: Pending
Project ID #: 1999
Description: This project is meant to improve fire protection water flow in the Cobblestone neighborhood only. No new water service connections are incluced. Several fire hydrants serving approximately 32 homes at the north end of Cobblestone Dr have sub-optimal fire flow ranging from approximately 752 gpm at 20 psi to 1329 gpm at 20 psi. A new 8" pipeline is proposed to connect the existing pipeline in Tillmont Way (located in the City's Pressure Zone R2) to the existing 6-inch diameter pipeline located in Cobblestone Drive (located in Pressure Zone R4).

Summer-Fall 2018: Environmental and Geotechnical studies are continuing. Some soil sound wave studies and borings will be necessary possibly using a small backhoe.
