4.Minor Revisions to the Draft Environmental Impact Report r Intersection of Bird Road and Blewett Road The analyses indicate that the intersection of Bird Road and Blewett Road is currently operating :I at an acceptable level of service. and is expected to eantinias to filinetion at adequate levels of sefviee thFough the year 2025 under all pFE)jeGt seenaries with construction afthe pmjeet. However,the near-term Haul Route 1 analyses indicate that a combination of the proposed project and the pending and approved projects will result in a level of service F during peak periods at the intersection. The intersection is expected to operate at a level of service E in the year 2025 even without the ` proposed project Haul Route 1 would exacerbate the cumulative year 2025 impacts to a level of service F. ` To mitigate the impacts created by Haul Route I on opening day,a southbound left-tum lane is required. v It is anticipated that traffic signal warrants will be satisfied based on the year 2025 cumulative traffic volume forecasts. To mitigate the cumulative 2025 impacts of Haul Route 1. traffic signals may be installed with a separate southbound left-tum lane and protected left-tum phasing Traffic r signals should not be installed until such time as the observed traffic volumes indicate signals are warranted. Haul Route 3 does not significantly impact the intersection.
