Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | SUMMARYTopic Alternative 1 Alternative 2 Alternative 3Gorst UGACreation of impervioussurface would result in theloss of soils on up to 41 netacres, as well as thefunctions that they provide(e.g., ability to supportnative plant species andother vegetation, andinfiltration of water), andcould contribute toincreased erosion of soils.Development on currentlyundeveloped parcels wouldresult in the long-term loss ofsoils and their functions on upto 70 net acres; though thealternative does recognizepublic park/open space areas.Creation of new impervioussurface could contribute toincreased erosion of soils.Construction on the mine sitecould require substantialmitigation, including projectdesign to minimize impacts tosoils and geologic resources.Developable land wouldequal about 69 net acres.This alternative includes thesame amount of open spaceas Alternative 2, as well asLow Intensity Waterfront,which reduces impervioussurfaces and promotesshoreline reclamation andopen space. Thereforesome soil functions wouldbe retained within thedevelopable land.Potential impactsassociated with the minesite would be similar toAlternative 2.Water ResourcesWater Quality and FloodingCommercial areas wouldlikely be redeveloped onthe previously disturbedimpervious surface withoutwater quality treatment andwould continue to impactfloodplains and theshoreline. Incrementalrestoration and potentialwater quality treatmentwould occur on waters thatare 303(d) listed.Overall, Alternative 2 wouldhave a minor effect on waterresources from short-termconstruction related impactsand moderate effects fromlong-term developmentcontinued development of highdensity commercial areas alongthe shoreline. The long-termeffects of the commercialdevelopment may be offset byimplementation of the adoptedWatershed Characterization &Framework Plan.Due to greater scrutiny ofpermits in floodplains and dueto the listing of fish species, thedevelopability of the GorstCreek floodplain area forintensive commercial uses isexpected to be challenging.Similar to Alternative 2.Air QualityEmissions from Vehicle Travel(VMT) due to Gorst UGAGrowthAlternative 1 wouldproduce 29,067 daily VMT,which would contribute lessthan one percent (0.4%) ofthe Kitsap County regionalVMT forecast for 2035.Alternative 2 would produce49,350 daily VMT (0.7%) lessthan one percent of the KitsapCounty VMT forecast for 2035.Alternative 3 wouldproduce 45,707 daily VMT(0.7%) less than onepercent of the KitsapCounty VMT forecast for2035.Gorst UGA Emission increase,metric tons CO2-equivalentper year compared to existingconditions7,474 14,371 12,922Draft | June 2013 1-13
