TA. - Page 113 LSA ASSOCIATES, INC. ROCKETSHIP REDWOOD CITY ELEMENTARY SCHOOL PROJECT SEPTEMBER 2016 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION A trip generation analysis was prepared for the project site (with and without the proposed project) using counts of vehicles entering and exiting existing driveways on November 4,2014,based on trip generation rates from the Institute of Transportation Engineers(ITE)Trip Generation Manual, 9th Edition for Automobile Sales; and also using peak hour trip rates from surveys conducted by Hexagon Consultants at existing Rocketship schools in San Jose between 2012 and 2014.As shown in Table 7,existing activities on the project site currently generate no trips during the AM peak hour and 3 trips during the PM peak hour. The proposed project would generate a net 462 trips during the AM peak hour and 247 trips during the PM peak hour. The proposed project would implement a Transportation Demand Management(TDM)Program to encourage students and employees to carpool,take transit,or use active modes of transport to get to and from school.Proposed TDM measures are outlined in the Traffic Study(Appendix F). The TDM Program is expected to reduce the vehicle trips and parking demand generated by the proposed project compared to that observed at other Rocketship schools,which do not have similar TDM programs. However,to be conservative,the analysis does not assume trip reductions for TDM measures.

Daily trip rate was derived by multiplying the AM Peak Hour rate by the ratio of daily trip rate to the AM trip rate(1.29/.45) available in the Institute of Transportation Engineers(ITE)Trip Generation Manual,9 h Edition for Elementary School(ITE Land Use 9520). d Peak hour trips from driveway counts conducted on Tuesday,November 4,2014.Daily trip rate was derived by multiplying the PM Peak Hour rate by the ratio of daily trip rate to the PM trip rate(32.3/2.62)available in the Institute of Transportation Engineers(ITE)Trip Generation Manual,9"Edition for Automobile Sales(ITE Land Use 11841). sf=square feet Source: Hexagon Transportation Consultants,Inc.,2016.Rocketship Redwood Academy at 860 Charter Street Traffic Study Report. September 28. Trip Distribution. The trip distribution pattern for the proposed project was estimated based on existing travel patterns on the surrounding roadway system and the locations of the complementary land uses.Four separate trip distributions were used in the study: 1) staff and visitors; 2)non-working parents; 3)incoming trips from working parents; and 4)outgoing trips for working parents. Trip distribution patterns are illustrated in the Traffic Study.
