Volume 2: Draft Gorst Planned Action Environmental Impact Statement

GORST PLANNED ACTION EIS | AFFECTED ENVIRONMENT, SIGNIFICANT IMPACTS, AND MITIGATION MEASURESLOS ImpactsOperational impacts were assessed by calculating the LOS of roadways and intersections in 2035 under trafficconditions projected to result from build-out of each of the three alternatives.Roadway segmentsTable 3.11-8 Projected Roadway Segment Deficiencies under Two Alternatives by 2035 summarizes the lane-milesof deficient roadway segments within the Gorst UGA projected by 2035 under the three alternatives. As notedearlier in this chapter, a county roadway is considered deficient if the projected V/C ratio exceeds the County’sadopted standards (Table 3.11-6 V/C Ratio Ranges as they Relate to LOS).Table 3.11-8Projected Roadway Segment Deficiencies under Alternatives by 2035Alternative 1 Alternative 2 Alternative 3Gorst Area Total Deficient Lane-Miles 0.46 0.46 0.46Total 2025 Gorst Roadway Lane-Miles 8.16 8.16 8.16Percent of Deficient Lane-miles 5.6 5.6 5.6Source: Kitsap County 2013Table 3.11-8 Projected Roadway Segment Deficiencies under Alternatives by 2035 shows that all three alternativesare projected to have a similar number of deficient lane miles. The projected 2035 volume on Belfair Valley Roadbetween Sam Christopherson Avenue and the UGA limits is expected to increase with all three alternatives to apoint where this section of roadway will be deficient by 2035. It is noted that this section of roadway wasidentified as needing improvement in the Kitsap County UGA Remand SEIS. None of the alternatives are expectedto result in a percentage of deficient lane-miles of roadway that exceeds the County concurrency standard of 15percent when considering either the Gorst UGA or for the entire County.IntersectionsDue to the uncertainty in timing and configuration of the state highway improvements within the Gorst UGA, anintersection analysis was not performed. It is recommended that as land is developed in the future, a traffic impactanalysis be prepared for the development that will look at the intersections within the area as well as thoseintersections outside of the Gorst UGA that could be affected.Impacts on State FacilitiesState HighwaysTable 3.11-9 Projected State Highway Deficiencies by 2035 summarizes the miles of deficient state highwaysegments projected by 2035 under each alternative. As noted earlier in this chapter, a county roadway isconsidered deficient if its operations are projected to exceed adopted highway standards (Table 3.11-8 ProjectedRoadway Segment Deficiencies under Alternatives by 2035).This table shows that Alternative 3 will have the least impact on the State Highways within the Gorst UGA in termsof the length of deficient roadway length with the Gorst area. Table 3.11-9 Projected State Highway Deficiencies by2035 shows that 1.87 miles of the 2.7 miles of SR 3 that is located in the Gorst Area will be deficient withAlternative 1 and 2 while 1.66 miles will be deficient with Alternative 3. None of the 1.14 miles of SR 16 within theGorst UGA is projected to be deficient by 2035.The table shows that 63 percent of the state highway miles in Kitsap County are projected to be deficient underAlternative 1 and 63 percent are projected to be deficient under Alternative 2.Draft | June 2013 3-170
