The study should be prepared in accordance with the Caltrans Guide for the Preparation of Trak Impact Studies, dated December 2002 (Guide). The Guide is available online at the following web address: http://www.dot.ca.gov/hq/tpp/Planning—tools/tools.htm. Minimum contents of the TIS are listed in Appendix "A" of the TIS guide. All State owned signalized intersections affected by this project should be analyzed using the intersecting lane vehicle (ILV) procedure from the Department's Highway Design Manual,Topic 406,page 400-21. • The Department requires level of service (LOS) "C" or better at State owned facilities, including intersections (see Appendix "C-3" of the TIS guide). If an intersection is currently below LOS "C," any increase in delay from project-generated traffic must be analyzed and mitigated. The LOS for operating State highway facilities is based upon treasures of effectiveness (MOE) (sec Appendix "C-2" of the Guide). If an existing State highway facility is operating at less than this target LOS, the existing MOE should be maintained. • The Department recommends that the Lead Agency encourage the developer to submit a scope of work for conducting the TIS prior to circulating the local development application for comment in order to expedite the Department's review. This will insure that the TIS submitted follows the Department's guidelines as stated in the Caltrans Guide for the Preparation of Trak Impact Studies, dated December 2002 (TIS guide). The TIS guide is available online at the following web address: http://www.dot.ca.gov/hq/tpp/planning_tools/tools,htin, • This proposed development may not create a major impact on SR-4 when considered by itself. However, when combined with the cumulative impacts of other existing and proposed development in this area,the resulting traffic will contribute to the significant congestion forecasted to the SR-4 mainline and at the 4 intersection of SR- 4/ Walker Lane Road. Therefore, the Department recommends the collection of impact fees on a "Fair Share" basis for future improvements to these facilities. "Callraas improv<s mobility&cross California"
