3.0 Environmental Impact Checklist intended to depict a "quality of life" impact as opposed to a substantial impact with respect to traffic congestion. In most cases, the local street system is designed to accommodate the relatively small increase in traffic volume;however, the impact as experienced by local residents is one the City seeks to mitigate through a range of options,most frequently through traffic calming techniques. This analysis is based on the Kentfield Traffic Impact Analysis Memorandum(Appendix F) prepared by the City of Redwood City Traffic Engineer and Planning Services for a similar residential project located on Kentfield Avenue in the vicinity of the proposed project. The proposed project would involve the construction of 12 two-story detached, single-family homes.As there are three existing single-family homes on-site,the project would result in the net increase of 9 new single family residences. Trip rates for the analysis are based on the Institute of Transportation Engineers(ITE)Trip Generation handbook. Table 5 provides the estimated net new trips resulting from the project. The project would result in 86 net new daily trips, 7 net new AM peak hour trips, and 9 net new PM peak hour trips.

Traffic counts taken in June 2008 indicated that 2,011 daily trips were taken on Kentfield Avenue between Woodside and Palm Avenue/Union Avenue. Based on the surrounding roadway network, it is estimated that the project traffic would be oriented towards Woodside Road rather than towards Palm Avenue/Union Avenue. The distribution of trips entering and leaving the project site is assigned as follows: • 60 percent to and from southeast(Woodside Road) • 40 percent to and from northwest(Palm Avenue/Union Avenue) The distribution of trips that approach or leave the project site via Woodside Road are further assigned as follows: • 33 percent to and from the west(Highway 280) • 67 percent to and from the east(Highway 101) Based on the estimated 86 net new daily project trips on Kentfield Avenue,and the project trip distribution of 60 percent of the trips to/from southeast of the site and 40 percent of the trips to/frorn northwest of the site,the project's traffic is estimated to increase volume on Kentfield La Palma Subdivision Project Final Initial Study/Mitigated Negative Declaration 58
