| 08/26/2003 | Doug Williams | ENGINEERING | REVIEW | Denied | SUBJECT: Insurance Auto Auction REVIEWER: Doug Williams DATE: 12 September 2003 ACTIVITY NUMBERS: T03CM01353-R/T03OT01508 SUMMARY: Engineering Division has reviewed the drainage report, Stormwater Pollution Prevention Plan (SWPPP) and report, and the site plan received on 23 August 2003. Approval of the Site Plan may not occur prior to drainage report approval, and is not recommended at this time. An engineering study review fee of $150.00 is required with the resubmittal, in accordance with Tucson Code, Section 26-11.2 i. The following comments are offered: DRAINAGE REPORT: 1. Please address/discuss potential adverse impact to adjacent properties or right of way (the increase in flow velocity specifically), at the northeast corner of the site, as a result of the proposed floodplain encroachment; 2. Provide an additional (east/west) cross-section for the basin inlet spillway, and include elevations and dimensions fully labeled, per the City of Tucson's Standards Manual for Drainage Design and Floodplain Management (SMDDFM), sec. 2.3.1.6 A 4 a; 3. Please omit the notes on Figure 4 indicating the 100-year Floodplain Limits are to be left natural. This does not appear to correspond with the intent and discussion contained in the report; 4. The report should address erosion protection measures at the basin discharge location; 5. Provide percolation test results with the resubmittal. Percolation test should be performed in accordance with the recommended procedures of the Pima County Department of Transportation-Flood Control District, and must demonstrate that the basin will percolate within the allowed time frame, as specified in section 3.5.1 of the Pima County/City of Tucson Stormwater Detention/Retention Manual (Development Standard -DS-10-01.0); 6. Provide a soils report addressing at a minimum, items a-d outlined in the SMDDFM, section 14.2.6 (DS 10-02.0); 7. Provide a minimum of one 15' wide vehicular access ramp into the basin, with a maximum slope of 15 percent, in accordance with the SMDDFM, section 14.3.4 (DS 10-02.0); 8. Please discuss the proposed 4" diameter orifice depicted in cross-section D-D, Figure 4; 9. Please remove the "min." notation for the outlet weir length of 9.3' on cross-section D-D, Figure 4; If you have any questions, I can be reached at 791-5550, extension 1189 or Dwillia1@ci.tucson.az.us.
