Sep- 19, 2006 217PM CA DEPARTMENT OF TRANSPORTATION No.5676 P. 3/4 i ! Mr. Hatef September 19, 2006 Page 2 2.. The body of the TIS states that the analysis results indicate that left-turn lanes should be installed for Moth directions on SR-88 at both project access driveways. However, in the section addressing Impacts and Mitigation Measures, the"Existing+ Approved +Project Traffic Levels" do not mention the left-turn lanes. The opposing traffic volumes are high enough that a westbound left-turn lane from SR-88 to Sierra will be necessary to prevent degrading existing traffic safety. 3. The TIS mentions that the Fast Access may need to be restricted in the future to right- in/right-out. The TIS states "So for the near-term it would not be necessary. . however, in the long term, it may be necessary to implement right-in/right- restrictions". The SR-88 project East Access, if ultimately proposed, shall be right-in/right-out only using a raised island or similar device from the opening date of the project, designed to restrict left turns in our out accordingly. The right-in/right- out condition at this access would not require the construction of the a westbound left turn pocket at this access. E 4. At the proposed Sierra Drive (south) intersection, the eastbound traffic volumes in conjunction with the project's expected PM Peals Hour right-turning vehicles will require a right-turn deceleration lane to safely remove decelerating right-turning vehicles from the through lane. 5. From past traffic counts taken on SR-88 prior to Clements Road, it appears that the peak hour traffic on Fridays and the weekends maybe significantly greater than the normal weekday commute AM and PM peaks. The Friday PM peak from(4:00 PM to 5:00 PM) taken by a traffic census hose count on July 8a', 2005 was 870 eastbound vehicles. i 6. Any proposed new and/or improved access to Sit,-88 from this development shall meet Caltrans public road intersection standards. 7. The TIS analysis indicates that at the approach on the south leg of the SR-88/Sierra Drive intersection, the queue length could extend back up to 325 feet. The Project Site Plan (Figure 1) indicates that taking the aforementioned information into account, the adjacent intersecting street in the subdivision should be moved further away from the SR-88 intersection to improve the function of both intersections. 8. Any access Improvements such as the left-turn pockets will need to be in place to mitigate project Impacts at the opening date of the subdivision. ."Caltrans impmvm moblliryacra.e.a 4Wi, mia"
