Engineering Division does not recommend approval of the site plan or grading plan at this time. The following items need to be addressed:


SITE PLAN COMMENTS:

1) DS Sec.2-02.2.1.A: Revise Sheet T.1 to replace all red lettering from the title sheet with black lettering to insure site plan clarity for reproduction and microfiche purposes.

2) DS Sec.2-02.2.1.A.4: Revise the project location map on Sheet T.1 to identify conditions within the square mile shown, such as watercourses and subdivisions adjacent to the site. Reference recorded subdivision plats by book and page numbers.

3) DS Sec.2-02.2.1.A.8: Revise the site plan to label the dimensions for the proposed back-up spur provided at the end of the PAAL located at the new car delivery area that is shown on the proposed site plan. The spur must have a minimum of a 3-foot radii and 3 feet in depth, but must also provide a minimum of 3 feet between the back of spur and any wall obstruction that is over 6 inches in height.

4) DS Sec.2-02.2.1.A.8: Provide a back-up spur at the end of each PAAL located at the proposed screen wall located on the northeast corner of the office building. Refer to DS Sec.3-05.2.2.D for requirements.

5) DS Sec.2-02.2.1.A.8: Provide wheel stop barriers for all parking stalls located adjacent to the pedestrian circulation areas. Wheel stop barriers are required at these locations to prevent parked vehicles from extending into the unobstructed 4-foot pedestrian circulation area.

6) DS Sec.2-02.2.1.A.8: Provide dimensions for all 2-way PAALs shown on the site plan. Verify that PAALs have a minimum 24-foot wide access area where gates are proposed and for parking stalls located across from proposed buildings.
