Page 3 of 5 • Water o Water main was installed as part of the surrounding developments with 6-inch, 8- inch, and 12-inch ductile iron pipe (DIP). o 515-feet of 6-inch watermain that serves 6 properties along Hwy-96 is proposed for replacement. This segment has a history of main breaks that would indicate poor condition of pipe. o Through recent inspections Public Works has identified a few hydrants and valves to replace which were not included in the initial estimate. o The installation of an additional hydrant along Amble Dr. is proposed. • Storm Drainage o Storm catch basin and manhole structures that are deteriorating and need repair have been identified by Public Works. o Retaining wall rehab near outlet pump (RCWD Grant eligible) o BMP-Phase 2 – surface water treatment from Cummings Park and adjacent property (RCWD Grant eligible) o Grit chamber improvement proposed for drainage from Karth Lake Circle (RCWD Grant eligible) o Storm sewer pipe televising identified spot repairs but overall good condition. o Dredging of formed deltas is proposed around outlet locations that discharge into Karth Lake, actual amount of sediment to be removed will be evaluated. o Curb and gutter is generally in good condition but spot replacement will be needed in some areas. Additional research regarding the age and condition of existing infrastructure will be evaluated during preparation of the feasibility report. Preliminary Project Budget From the 2025-2029 CIP, the initial cost estimate is summarized in the following table and will be revised as part of the feasibility report. This estimate includes the anticipated costs for engineering design, surveying, and construction administration as a 27% contingency, which is consistent with previous PMP projects since 2021. * Initial estimate subject to revisions during the feasibility study Category CIP Budget Streets $1,720,000 Storm Drainage $500,000 Sanitary Sewer $145,000 Water Utility $120,000 TOTAL $2,485,000
