Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | SUMMARY• Existing plan policies or concepts under Alternative 1 or features of the proposed Watershed Characterization& Framework Plan, Gorst Subarea Plan under Alternatives 2 and 3 – that serve as mitigation.• Applicable regulations and commitments at the federal, state, and local level that would mitigate impacts.• Other potential mitigation that could modify current or proposed plans or regulations.For the full text, consult Chapter 3.0, Affected Environment, Significant Impacts, and Mitigation Measures.Geology/SoilsIncorporated Plan FeaturesNew plans that would be implemented under Alternatives 2 and 3 include features that would serve as mitigationfor potential impacts to soils and geologic resources. Implementing regulations associated with the Gorst SubareaPlan, and Gorst Creek Watershed Characterization & Framework Plan would incorporate the suggestedmanagement measures shown in Table 2-8 Integrated Watershed Processes and Habitat Results and ManagementMeasures.Possible plan features that would serve as mitigation for potential impacts to soil include the following:• Minimization of new development in certain areas.• Limiting logging activities and maintain appropriate zoning in areas with high sediment export.• Implementation of measures to reduce erosion and sediment export in areas identified for futuredevelopment (e.g., buffers, setbacks from steep slopes, reduction of overland flow through infiltration).• Restoration of cleared/degraded areas.• Implementation of stormwater retrofits to reduce impervious surface.Additionally, capital facility improvements have been recommended for addressing stormwater deficiencies andflooding issues. Implementation of these improvements would help reduce soil erosion and loss of soil from thewatershed. Based on policies in the proposed Draft Gorst Subarea Plan and Draft Gorst Creek WatershedCharacterization & Framework Plan implementing regulations could include a zero stormwater dischargerequirement limiting direct and untreated stormwater and a requirement that future development incorporate aseries of LID measures to infiltrate or detain runoff.Applicable Regulations and Commitments• Kitsap County CAO• City of Bremerton CAO• KCC Chapter 12, Stormwater Drainage, and Kitsap County Stormwater Design Manual.• BMC Chapter 15, Stormwater Management Manual for Western Washington (SWMMWW) and LID GuidanceManual.Other Potential Mitigation MeasuresNo additional mitigation measures are proposed for soil and geologic resources.Water ResourcesIncorporated Plan FeaturesFeatures of the Watershed Characterization & Framework Plan and Gorst Subarea Plan that serve as mitigation forpotential impacts on water resources include the following concepts found in Guiding Principles and Goals andPolicies:Draft | June 2013 1-23
