The <br />all -way stop intersection of Pock Lane & Boeing Way would continue to operate at LOS <br />E in the a.m. peak hour, with an increase of 3.1 seconds of average delay. In addition, the <br />signalized intersection of Mariposa Road & 8th Street/Farmington Road would degrade <br />to LOS E. <br />The Traffic Impact Study recommended that signal timing optimization using Synchro 11 <br />methodology would allow the Mariposa Rd. & 81 Street intersection to operate at <br />acceptable LOS. As with Existing plus Project Conditions, the impact at Pock Lane & <br />Mariposa Road can be eliminated with the addition of a northbound right -turn lane. At <br />the Pock Lane & Boeing Way intersection, the westbound approach would experience <br />substantially more delay than the other three approaches in the a.m. peak hour. By <br />providing a separate right -turn lane on this approach, operations would be improved to an <br />acceptable LOS. <br />In its review of the Traffic Impact Study, the County stated that the installation of the <br />northbound right -turn lane at Pock Lane & Mariposa Road would be a condition of <br />approval of the project, as previously noted. The County determined that the project <br />would not be required to pay fair -share costs for the other two recommendations, as it is <br />assumed that signal optimization will be looked at from now to 2040 and the addition of a <br />lane at the intersection of Pock Lane/Boeing Way could be completed by restricting <br />parking and restriping since the area is fully built out with curb/gutter. Based on the <br />County findings, the project would be consistent with the LOS standards set forth under <br />Pock Lane Public Review Draft IS/MND 3-77 May 2022 <br />
