Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | AFFECTED ENVIRONMENT, SIGNIFICANT IMPACTS, AND MITIGATION MEASURESMitigation MeasuresIncorporated Plan Features• Focusing growth in existing UGAs and cities where solid waste services already exist would reduce impactsrelated to providing curbside pickup for added population and promote more curbside customers. Therewould also be less need for additional RAGFs.Applicable Regulations and Commitments• Coordination and monitoring at transfer facilities and RAGFs would be ongoing to ensure adequate solid wastecapacity. Service levels for curbside collection as outlined in the CFP would continue or improve to encouragerecycling.Other Potential Mitigation Measures• Based on available landfill capacity at the County’s current contracted landfill location a new or extendedcontact could be enacted to provide landfill capacity well beyond the 2025 planning horizon.Significant Unavoidable Adverse ImpactsFuture population growth and development would continue to increase the amount of solid waste generated inthe county under any alternative, especially the action alternatives. With Solid Waste Management Plans, regularlyupdated as appropriate, no significant unavoidable adverse impacts are anticipated.3.13.3. Water, Wastewater, and StormwaterThis section describes the environmental considerations related to utilities in the study area. An evaluation andreview of existing levels of service, estimated needs and demand for service, and projected levels of service undereach alternative for water, wastewater, and stormwater is provided. Surface water, groundwater, and waterquality was previously described in Section 3.2 Water Resources. The utilities analysis is based on the stormwaterplan and capital improvement program. Utilities information was collected from the City of Bremerton CityServices Element of the Comprehensive Plan (City of Bremerton 2010) and City of Bremerton GIS data. Othersources used in this analysis include: Gorst Creek Watershed Characterization Report (City of Bremerton 2012),Gorst Creek Watershed Inventory and Characterization Technical Memorandum (Parametrix 2011), and KitsapCounty’s 2013-2025 CFP (Kitsap County 2012).Affected EnvironmentWatershedWaterWater (drinking) for residents in the watershed is supplied from City of Bremerton utility lands and also theAnderson Creek aquifer. Primary water service is provided by both the City of Bremerton and Port Orchard in thestudy area. The Sunnyslope Water District No. 15 provides water to unincorporated rural areas in the watershed.The Gorst aquifer currently has five wells and six wellhead protection areas. The City of Bremerton supplies waterto the Gorst UGA and portions of the SKIA UGAs (City of Bremerton 2012). The City of Bremerton partially supplieswater to the McCormick Woods area. There is one reservoir in the watershed, which is not in the City ofBremerton, located near the Twin Lakes area, just upstream from the Gold Mountain Golf Course. There are twomajor water mains in the watershed. One of the water mains is a 28-inch diameter pipe installed in 1950 along WBelfair Valley Road and Gorst Creek that supplies water from the Union River reservoir and surrounding wells formthe Gorst UGA. The other 18-inch water main, which was installed in 1976, follows the shoreline of Alexander Lakeand then heads along Heins Creek to the Gorst UGA. Two water pump stations are located in the watershed, one inthe central portion of Gorst Creek (Pump Station #3) and the other along W Belfair Valley Road near DivisionDraft | June 2013 3-222
