DATE: 2 February 2004 ACTIVITY NUMBERS: T03CM05845/T03BU03175 SUMMARY: Engineering Section has reviewed the Drainage Report, Site Plan and Grading Plan received on 15 January 2004. Approvals are not recommended at this time. Please address the following comments: DRAINAGE REPORT: 1. Please provide the site address that corresponds with the site and grading permit applications (1016 E. Milton Rd.) on the drainage report cover sheet and in the introduction, in accordance with the City of Tucson's Standards Manual for Drainage Design and Floodplain Management (SMDDFM), Section 2.3.1.1 B (Development Standard - DS 10-02.0). 2. Specify the name, address and telephone number of the person(s), firms(s), agency or agencies responsible for the ownership, operation, scheduled and unscheduled maintenance and liability of the detention basins described in the report (SMDDFM, Section 2.3.1.2 E). 3. The text in the report states this site is not affected by any offsite drainage sources, yet existing photo-contours indicate there may be flows entering the site from the east and possibly south. Please address acceptance of offsite flows, with flow-through wall opening calculations and recommendations in a revised report. The report should include a topographic map at a scale of one inch = 200' or larger, or preferably a photo-topo showing the applicable items listed in section 2.3.1.3 A 3 of the SMDDFM. 4. All retention/detention basins within the City of Tucson must have a minimum of one maintenance access ramp. The City of Tucson's Standards Manual for Drainage Design and Floodplain Management (Development Standard 10-02.0), Section 14.3.4, states that, "a minimum of one 15-foot wide vehicular access ramp shall be provided into each basin. The maximum roadway or access ramp slope shall not exceed 15 percent. Alternate means of access will be reviewed by the City Engineer on a case-by-case basis". Please discuss an appropriate ramp in the drainage report and depict on the site and grading plans, labeled and dimensioned, addressing this requirement. 5. As a part of the basin maintenance checklist, provide the summaries outlined in section 2.3.1.6 C 2, of the SMDDFM. 6. Please provide percolation test results with the resubmittal. Test results are required to be submitted with the drainage report, in accordance with section 3.5.1 of the Pima County/City of Tucson Stormwater Detention/Retention Manual. Testing shall be performed in accordance with the recommended procedure of the Pima County Department of Transportation - Flood Control District. 7. Please provide a soils report with the resubmittal. Soils reports are required in conjunction with the design of each surface facility that utilizes infiltration as a method of basin drainage. The report shall at minimum address minimum recommended setbacks to structures, soil permeability, erodibility, slope stability and groundwater elevation (Section 3.5.1.5, DS 10-01.0). 8. The report should address an appropriate erosion control or energy dissipation structure at the detention basin outlet weir. The pad must be located onsite, and be designed to return flows to pre-developed conditions location and magnitude, as nearly as possible, prior to exiting the site (Section 3.3.3, DS 10-01.0). SITE PLAN: 1. Depict the location and size of maintenance access ramps and roadways, in accordance with the City of Tucson's Standards Manual for Drainage Design and Floodplain Management (SMDDFM), Section 2.3.1.6 A 4 b (Development Standard 10-02.0). 2. Provide the 100-year ponding limits with water surface elevation noted (SMDDFM, Sec.2.3.1.6 A 4 e). 3. Depict and label minimum unobstructed radii of 18' at the driveway entrances onsite (DS 3-05.2.1 C 3 a). 4. Identify and label proposed driveway aprons in the right of way to be constructed in accordance with Pima County/City of Tucson Standard Detail (SD) 206, or provide 18' radius curb returns, with curbing to be constructed per SD 209. 5. Omit or revise the Floodplain Note on sheet 2.0. 6. Provide and label roof downspout locations with corresponding sidewalk scuppers south and southwest of the storage/office building. 7. Please provide a typical flow-through wall opening detail with clear notation of opening size, spacing and location(s), in accordance with a revised drainage report (see drainage report comment #3). 8.

GRADING PLAN: 1. Please provide grading limits and the total area to be disturbed. 2. Provide a Grading Note specifying conformance to excavation and grading requirements outlined in the 2000 International Building Code - local amendment. These may be accessed at http://www.ci.tucson.az.us/dsd/2000_IBC_Amendments.pdf 3. Please provide ease-west and north-south cross sections for basin A2, fully labeled and dimensioned, and ensure the former section depicts a 2'setbacak from property line. 4. Provide any wall opening details, as may be indicated in a revised drainage report, and include a detail or cross section for conveyance and/or water harvesting along the eastern (2' wide) perimeter. 5. Revise the riprap splash pad to be constructed within the property limits. ***GENERAL COMMENT*** A right of way excavation permit will be required for any proposed work in the right of way.
