| 02/06/2004 | Loren Makus | ENGINEERING | REVIEW | Denied | SUBJECT: Site, Grading and Drainage review - 1050 E. Milton Rd. DATE: 10 February 2004 ACTIVITY NUMBERS: T03CM05846/T03BU03176 SUMMARY: Engineering Section has reviewed the Drainage Report, Site Plan and Grading Plan for the Park Avenue Apartments. The Site Plan, Drainage Report and Grading Plan cannot be approved 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). The permit applications and submittals for this project and for the adjacent project have been mismatched. This must be corrected for the next submittal. 2. 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. 3. 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. 4. 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. 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 #2). 8. Provide a note for stormwater harvesting maximization in all landscape areas, in accordance with Section 14.2.10 of the SMDDFM and Section 3.7.4 of the City of Tucson's Land Use Code (LUC). 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 east-west and north-south cross sections for the retention basin, fully labeled and dimensioned, and ensure the sections depict 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 COMMENTs A right of way excavation permit will be required for any proposed work in the right of way. Contact Permit and Codes Section, Tucson Department of Transportation - Engineering Division at 791-5100 for questions. This project is part of a larger common plan of development or sale as defined by the AzPDES Construction General Permit. Prepare and submit a Stormwater Pollution Prevention Plan (SWPPP) for this project and for the adjacent Milton Apartments project. (Provide either one SWPPP for both projects or provide a separate SWPPP for each.) If these projects qualify for a waiver, submit a copy of the certification and provide the beginning and ending dates for the projects. Resubmittal will require a revised Site Plan, Drainage Report, Soils Report, SWPPP and Grading Plan addressing all items listed above. If you have any questions, I can be reached at 791-5550, extension 1161 or LMakus1@ci.tucson.az.us Loren Makus Sr. Engineering Associate Engineering Division Development Services Department |
