n. Depress all landscaped areas a maximum of 6" for waterharvesting"

5- Provide the administrative address.
6- Correct the detail sheet number in all applicable Grading, Drainage & Paving Notes on Sheets C-1.4 and C-1.5. (i.e. the notes refer to sheet C-1.6 for details).
7- Grading, Drainage & Paving Note #13 does not clarify where the width of the sidewalk is noted. Provide the width of all proposed sidewalks.
8- Revise Grading, Drainage & Paving Note #9 to include the installation of Filter Fabric underneath the dumped riprap.
9- Provide Grant Road grades to compare them to proposed onsite grades. Additionally, it appears that the western entrance area is proposed to be lowered close to 2 feet. Explain how this grade change might affect the general drainage in that area.
10- Based on a field investigation, it appeared that the topography in the dirt area, shown on Sheet C-1.5, does not match what is on the ground. Do the shown contour lines represent the old topography before the area was grubbed and graded?
11- The Drainage Statement does not address the proposed wall openings, erosion control pad and check dam. These drainage structure designs need to be incorporated in a revised drainage statement. Additionally, ensure that the check dam will not cause any back water that might create adverse impact on the parking lot. Provide a revised drainage statement that addresses theses issues.
12- Provide additional construction details for the proposed check dam (i.e. riprap will be dumped or grouted, riprap and course aggregate sizes, the use of filter fabric, the required key in's and toe down's, additional structure dimensions, etc.).
13- Provide the dimensions of the erosion control pad proposed at the end of the valley gutter, shown on Sheet C-1.5. Additionally, provide the size and the thickness of the proposed riprap.
14- Provide the proposed width of the valley gutter at the end of the flare as it connects to the riprap pad.
15- It is not clear where Details 6, 8 and 11 are referenced on the plan.
16- Work in the public right of way requires an excavation permit and/or may require a private improvement agreement. Check with City of Tucson Department of Transportation Permits and Codes for additional information.
17- Resubmit the redlined grading plan with future Grading Plan submittals for comparison.
