Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | AFFECTED ENVIRONMENT, SIGNIFICANT IMPACTS, AND MITIGATION MEASURESClimate Change in the Kitsap County Energy Efficiency and Conservation PlanThe 2011 Kitsap County Energy Efficiency and Conservation Plan (Kitsap County 2011) includes a list ofrecommended policies and actions to reduce energy use and encourage renewable energy projects. In addition toachieving greater energy efficiency and energy cost reductions, one of the primary goals of the plan is to reduceGHG emissions.Climate Change in the City of Bremerton SKIA Subarea PlanThe City of Bremerton’s SKIA Subarea Plan applicable to a portion of the western watershed includes developmentregulations and incentives that are intended to reduce vehicle trips, encourage alternate modes of transportation,increase energy efficiency, and reduce GHG emissions within SKIA.MethodologyLand Use Values Used for Air Quality and GHG AssessmentsPlanning in the Gorst Creek Watershed includes a review of two geographies, the Gorst UGA where land usechanges are under consideration and the larger Gorst Creek Watershed which would retain current land use plansbut which would show some amount of growth, nevertheless. Each portion of the study area is considered in thissection.This analysis considered future land use growth and future emissions increases in the Gorst UGA. The proposedsquare footage of commercial and industrial space in the Gorst UGA would be higher for the no action alternative(Alternative 1) than under Action Alternatives 2 and 3, whereas population growth is expected to be higher forAlternatives 2 and 3 than under Alternative 1. Table 3.3-2 Assumed Land Use and Population Growth for GHGEmission Calculations–Gorst UGA lists the land use values that were used to assess regional VMT) and regionalGHG emissions.Table 3.3-2Assumed Land Use and Population Growth for GHG Emission Calculations–Gorst UGANet Increase under Alternatives Compared to ExistingConditionsLand Use Type Existing Alternative 1 Alternative 2 Alternative 3Single-family (dwelling units) 88 33 25 10Multifamily/Townhomes (dwelling units) 18 0 513 587Commercial (square feet) 78,000 316,319 286,325 157,375Light Industrial (square feet) 78,489 76,336 32,128 17,659Note:Existing dwellings are based on US Census block group household data for 2010. Existing square feet are derived fromEmployment Security Department numbers of jobs (as provided by PSRC) for 2010, multiplied by 969 square feet peremployee for industrial uses and 500 square feet per employee for commercial uses. This matches Kitsap County’sComprehensive Plan assumptions.Future estimates of growth are based on each alternative proposed land use and zoning as well as a land capacityanalysis consistent with Kitsap County’s Urban Land Capacity Analysis as updated for the Kitsap County UGA Resizingand Composition Remand in 2012.In addition to considering growth in the Gorst UGA, this analysis also considered future land use growth and futureemissions increases in the Gorst Watershed. Table 3.3-3 Assumed Land Use and Population Growth for GHGEmission Calculations Gorst Watershed, excluding Gorst UGA provides land use values that were used to assessregional GHG emissions.Draft | June 2013 3-31
