RESUBMITTAL REQUIRED: Grading Plan, Drainage Report and SWPPP

The Grading Plan (GP), Drainage Report (DR) and Stormwater Pollution Prevention Plan cannot be approved as submitted. Please address the following review comments prior to the next submittal.

Grading Plan:
1. Please include a response letter to the comments along with the corrected copies of the GP.
2. This grading plan was reviewed under a separate activity number, hence the "entire" set did not accompany the grading plan for review and notes on the grading plan referred to details on sheets that could not be reviewed. Submit the entire set of plans if the GP page will be referring to other sheets in the set or include the pertinent details/sections with the GP.
3. Add note: "Depress all landscaped areas a maximum of 6" for water harvesting"
4. Add the basin(s) maintenance responsibility note per S.M.D.D.F.M. 2.3.1.6 C 1 and 2 to the GP.
5. List administrative address/site address on plans.
6. List GP number (T06BU02309) on all sheets.
7. Provide a Location Map (3" = 1 mile)
8. Include the basin details (dimensioned plan view) on the grading plan.
9. All basins must be graded to drain.
10. The basin discharge pipes shall have a smaller orifice than the pipe size. Revise as required.
11. Show all symbols in the legend.
12. Show cross sections with transverse and longitudinal slopes.
13. Please show the proposed roof drainage patterns, 100% of the 10-year flow must be conveyed under the sidewalks. Please provide supporting calculations to demonstrate compliance with D.S. 3-01.4.4. If the location(s) of the roof scuppers have not yet been decided, add a general note indicating sidewalk scuppers (per COT/SD) will be used when the roof scuppers locations have been designed.
14. Call out surface paving material. It appears that the same material designation for the basin maintenance ramp is being used for the 3" AC designation. Differentiate between the two.
15. Curb and Gutter elevation include drainage flow with percent slope.
16. Show details of all surface materials including but not limited to riprap aprons, catch basins, channels etc. All riprap shall be lined with an approved filter fabric.
17. A permit or a private improvement agreement will be necessary for any work performed within the Right-of-way. Contact Permits and Codes at (520) 791-5100 for permit information.
18. Show the 100-year flood peak discharge.
19. Call out all slopes and stabilization material (concrete, riprap, gabbions or vegetation).
20. Cut or fill slopes require a 2' minimum setback from property line.
21. Drainage patterns with percent slopes (Show patterns within the first 100 feet from the property line).
22. Flow arrows, grades and flow rates within and adjacent to site to show drainage scheme.
