Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | SUMMARY• Identify and protect critical areas such as floodplains along Gorst Creek.• Prioritize areas for restoration that would improve water quality.• Protect and enhance water quality/quantity.• Promote shoreline reclamation.Additionally, capital facility improvements have been recommended to address runoff from impervious surfacesand flood-prone areas.Applicable Regulations and CommitmentsSurface water quality standards are implemented through the Clean Water Act Section 401 certifications, waterquality modifications, and compliance with the standards in Chapter 90.48 RCW and WAC 173-201A. Applicationsfor water quality related permits include the Joint Aquatic Resources Permit Application (JARPA) process, and theNPDES permits. In addition there are shoreline and critical area regulations applied by the City and County.Other Potential Mitigation MeasuresOther potential mitigation measures could include the following:• During construction, future projects will need to comply with all construction-related stormwaterrequirements, including temporary erosion and sediment control, and development and implementation of astormwater pollution and spill prevention plan.• The project-specific design will determine the necessary permanent, long-term water quality treatmentrequirements, necessary for all vehicle-accessible areas and redevelopments. Large areas of landscaping orlawn, unless strict policies on pesticide and fertilizer use are adopted, will also be subject to water qualitytreatment requirements.• No specific water quality treatment method is proposed at this point, but it is likely that treatment wouldconsist of various LID systems to the extent feasible. Additional erosion protection improvements may beneeded at project outfalls because of increased peak runoff rates caused by an increase in impervious surface.• If Gorst Subarea Plan policies and BMPs are implemented with corresponding development regulations therewould be incentives for the removal of existing impervious areas and smaller new impervious footprints.Implementation of these types of incentives and standards could result in beneficial effects on waterresources.The concept of allowing commercial or mixed uses on smaller impervious footprints could be extended to theGorst Creek corridor and floodplain similar to Low Intensity Waterfront designation, recognizing the convergenceof critical areas and difficulties of development in the floodplain. This would replace portions of CommercialCorridor in Alternative 2 and Gorst Mixed Use in Alternative 3.Air QualityIncorporated Plan FeatureThe Gorst Subarea Plan includes policies promoting compact development as well as a policy on adapting to sealevel rise. It also includes policies promoting incentives for increased heights and densities, increased landscaping,and energy reduction that could encourage GHG reduction. In addition Kitsap County and City of BremertonComprehensive Plans include additional land use and transportation goals that would encourage GHG reduction.Applicable Regulations and Commitments• National Ambient Air Quality Standards• State Ambient Air Quality StandardsDraft | June 2013 1-24
