Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | SUMMARYincrease by less than 35 percent over existing (2010) volumes. Based on the modeled data, traffic noise would beexpected to increase by less than three dB(A), a change that is barely perceptible to the average human ear.Land use within the Gorst UGA under all alternatives would include residential and commercial use to varyingdegrees. New commercial development would likely occur near existing or future residences and other sensitivereceivers.Hazardous MaterialsWatershed. Under all alternatives, development and redevelopment would occur within portions of the GorstCreek Watershed. Three sites in the watershed outside of the Gorst UGA are currently releasing hazardousmaterials to the environment, although it is assumed that some level of cleanup of these sites would occur in thefuture under all of the alternatives. Redevelopment of these sites would likely include construction activities thatcould disturb contaminated areas, exposing workers, soil, groundwater, and/or surface water to hazardousmaterials. Additionally, construction activities elsewhere in the watershed could expose new contamination notpreviously documented, which would provide opportunities for remediation. Demolition of existing structuresunder any of the alternatives could be associated with risks to workers from exposure to lead-based paint and/orasbestos containing materials (ACMs).Gorst UGA. One Reasonably Predictable and seven Substantially Contaminated Sites have been identified withinthe Gorst UGA. Many of these sites are currently undergoing cleanup or remedial actions, and it is likely thatcleanup actions would continue into the future under all of the alternatives. However, since many sites in the UGAare currently documented as storing hazardous substances or waste, it is likely that additional contaminated siteswill be discovered in the future. As discussed for the watershed, there would be risks associated with exposures orreleases of hazardous materials during redevelopment activities, including disturbance of contaminated soil,demolition of buildings with lead-based paint or ACMs, and use/storage of hazardous materials at constructionsites.Land Use PatternsUnder all alternatives, additional growth is anticipated in the Gorst UGA. Vacant land would, over time, bedeveloped for commercial, residential, recreational, or industrial use, as allowed by the land use and zoningdistricts adopted under that alternative. Properties occupied by nonconforming uses would eventually beredeveloped in a manner consistent with adopted zoning, and new development and redevelopment would alsoentail the eventual modification or demolition of some existing structures, as well as the construction of newbuildings, which could cause temporary construction-related impacts, such as increased levels of noise, fugitivedust, and vehicle traffic.Socio-EconomicsWatershed. Outside the Gorst UGA, it is not expected there will be any differences for the Gorst Creek Watershedin terms of population and employment growth between the alternatives. Population growth will most likely occuron rural lots in the areas designated Rural Residential and Urban Reserve in the southern part of the watershed.Both designations limit development to relatively low densities. Rural Residential allows one dwelling unit per fiveacres and Urban Reserve allows one unit per 10 acres. Commercial and employment growth will most likely occurwithin parts of SKIA and Bremerton in the watershed. Impacts from the large increase in jobs in SKIA are addressedin the SKIA Subarea Plan and EIS.Gorst UGA. Under all alternatives, additional growth is anticipated in the Gorst UGA. The number and compositionof people and housing varies considerably by alternative. See Table 1-2 Comparison Matrix of Impacts.Draft | June 2013 1-9
