TJ KM Transportation Consu Itants Table II shows the expected trip generation for the proposed project. Overall,the proposed project is expected to generate a net increase of approximately 9 a.m. peak hour vehicle trips (6 inbound, 3 outbound), 12 school p.m. peak hour vehicle trips (2 inbound, 10 outbound), and I 6 commute p.m. peak hour vehicle trips (9 inbound, 7 outbound).

Daily trips at existing jewelry store were conservatively estimated based on peak hour counts at the site. Project Trip Distribution and Assignment TJKM developed trip distribution assumptions for the proposed project based on the collected existing turning movement counts and knowledge of the study area, in coordination with City staff. The estimated trip distribution is as follows: • To/from EI Camino Real North —45 percent • To/from EI Camino Real South — 35 percent • To/from Oakwood Drive West - 20 percent • To/from Dumbarton Avenue East— less than one percent Net project trips were assigned to the existing roadway network based on the above distribution and added to Existing turning movement counts. These assigned trips are illustrated in Figure 4. The resulting study intersection volumes for Existing plus Proposed Project Conditions are shown in Figure 5. Intersection Level of Service Analysis— Existing plus Proposed Project Conditions Table III summarizes peak hour levels of service at the study intersection under Existing plus Proposed Project Conditions. LOS worksheets are provided in Appendix D. Under Existing plus Proposed Project Conditions, the EI Camino ReaUOakwood Drive/Dumbarton Avenue intersection is expected to continue operating acceptably at LOS C or better,just as under Existing Conditions, with minor changes in average vehicle delay.
