Ms. Hatef Fcbrttary 7, 2007 page 2 • This proposed development has the potential to create an impact on. SR-99. When combined with the cumulative impacts of other existing and proposed development in the area, the resulting traffic will contribute to the significant congestion forecasted on both facilities_ The Department supports the concept of"Fair Share Contributions" on the part of developers due to traffic impacts by the proposed development. Therefore, it 1s our recommendation that the developer contribute their fair. share for future improvements to SR-99 and I-5 mainlines, and interchanges with Eight Mile Road_ « A traffic impact study (TIS) is necessary to determine this proposed project's near- term and long-term impacts to State facilities --both existing and proposed--and.to propose appropriate mitigation measures. The Department recommends that the study be prepared in accordance with the Caltrans wide,for the Preparation of Traffic Impact Studies, dated December 2002 (Guide). The Guide is available online at the following web address: bttp://Nvww.dot.ca.gov/bq/tpp/planning2ools/tools.htrn- 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 400-20. o The TIS needs to evaluate the peak hour traffic generation and the impacts of the church's proposed driveways on the operations and.Level of Service (LOS) of the adjacent intersections at the ramps and frontage road. Additionally, it would need to analyze any effect to the LOS of segments of Eight Mile Road, If so, it would need to mitigate impacts. o The Department endeavors to maintain a target LOS at the transition. between LOS C and LOS D on State highway 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 should be analyzed and mitigated. The LOS .for operating State highway facilities is based upon measures of effectiveness (MOE) (see Appendix "C-2" of the Guide). If an existing State highway facility is operating at Icss than this target LOS, the existing MOE should be maintained. o A proposed project only select zone analysis - trip generation and assignment for build-out of general plan — is required to complete the review of this project.
