| 09/15/2004 | DOUG WILLIAMS | ENGINEERING | REVIEW | Denied | SUBJECT: Drainage Report, Site Plan Grading Plan and Stormwater Pollution Prevention plan review DATE: 14-15 September 2004 ACTIVITY NUMBERS: T04CM03716/T04BU02032 T15S, R13E, Section 15 Engineering Division has reviewed the Subject items. Approvals are not recommended at this time. Please provide revised site, grading and SWPP plans, drainage report, "red/green line" markups for reference, and a response letter addressing all of the following comments: DRAINAGE REPORT: 1. Specify the name, address and telephone # of the person(s), firm(s), agency or agencies responsible for the ownership, operation, scheduled and unscheduled maintenance, and liability of the drainage improvements described in the report, and list any other documents where these responsibilities are documented, in accordance with Section 2.3.1.2 E of the City of Tucson's Standards Manual For Drainage Design and Floodplain Management - SMDDFM (Development Standard 10-02.0). 2. Discuss and provide recommendations for minimum setbacks from the retention basins for the proposed building, or provide additional geotechnical engineering recommendations from Terracon - the soils report does not specifically address minimum setbacks, as required per Section14.2.6 of the Drainage Standards Manual (DS 10-02.0). 3. Discussion in the second paragraph on page 7 specifies a shared inlet/maintenance access ramp. Please revise the report as necessary to specify minimum 15' wide vehicular access ramps with slopes not to exceed 15% for both basins (Section 14.3.4 - DS 10-02.0). 4. Provide retention basin percolation test results in the revised drainage report. Include discussion/analysis of the test results to assure the maximum allowed time of disposal will not be exceeded for each basin, in accordance with Section 3.5.1 of the Pima County/City of Tucson Stormwater Detention/Retention Manual (DS 10-01.0). 5. Omit or revise the last sentence of the fourth paragraph under "Post-developed Conditions" (page 5). A scupper will be required for conveyance under sidewalk area(s). 6. Omit the portion of the last sentence on page 8, referencing a dry well as an alternative to infiltration/percolation. 7. Omit or revise the second to last paragraph on page 9, referring to maintenance access from the private street. Basin maintenance access shall occur on the property. 8. Provide individual retention basin 100-year water surface elevations, outlet weir elevations, and erosion protection (riprap) sizing and dimensions - preferably on the Drainage Concept or elsewhere in the report (Section 5.2.6 - DS 10-01.0). 9. Please refer to Sections 3.5.1.1 - 3.5.1.4 of the Stormwater Detention/Retention Manual for additional retention/detention design guidelines, maximum disposal times, etc. SITE PLAN: Please refer to Development Standard (DS) 2-02.2.0 Site Plan Content and Specifications. Revisions to the drainage report may result in necessary revisions or additions to the site and grading plans. Please assure all new construction related items and revisions are depicted on the grading plan. 1. Depict and label new sidewalks and curb access ramps along the entire property frontage, in accordance with Development Standards 3-01.3.3, 3-01.2.7, 2-08.4.0. 2. Provide 100-year water surface elevations for each basin (DS 2-02.2.1.15) 3. Provide dimensioning from street monument lines to all existing curbs, sidewalks and utility lines (DS 2-02.2.1.21) 4. Specify a minimum 5" thick concrete slab and bollards to be placed on the rear and side walls of the dumpster (and enclosure, should one be required). Provide an enclosure detail if so, and assure a minimum of 20 feet between sidewall bollards is dimensioned (DS 6-01.4.0). 5. Depict the refuse container size and access thereto, fully dimensioned and labeled. A clear approach of 14' x 40' is required for service vehicles, with minimum inside and outside turning radii of 36' and 50', respectively (DS 2-02.2.1.32 & DS 6-01.4.0). 6. Depict and label roof drainage direction, all downspout locations and corresponding sidewalk scuppers for conveyance of 100% of the 10-year flow event under all sidewalk areas (DS 2-08.4.1 E and 2-08.5.1 E). 7. Provide a note on the plan stating that, (a) the owner or owners shall be solely responsible for operation, maintenance, and liability for drainage structures and detention basins; (b) that the owner or owners shall have an Arizona Registered Professional Civil Engineer prepare a certified inspection report for the drainage and detention/retention facilities at lease once each year, and that these regular inspection reports will be on file with the owner for review by City staff, upon written request; (c) that City staff may periodically inspect the drainage and retention/detention facilities to verify that scheduled and unscheduled maintenance activities are being performed adequately; and (d) that the owner or owners agree to reimburse the City for any and all costs associated with the maintaining of the drainage and detention/retention facilities, should the City find the owner or owners deficient in their obligation to adequately operate and maintain their facilities" (DS 10-02.0, Section 14.3.2). 8.

Ensure property lines, setbacks, any curbing and sidewalks are included in each, at a minimum. 8. Revise and include all construction details and notes consistent with a revised drainage report and site plan. 9. Due to concerns regarding basin infiltration requirements, please add the following General Note: "Infiltration test results shall be submitted upon basin completion after 90% grading construction is complete. The Certificate of Occupancy shall be held until function of the basins are determined to meet design requirements as specified per the approved Site and Grading plans, drainage and geotechnical reports". STORMWATER POLLUTION PREVENTION PLAN (SWPPP): Please submit three copies of SWPPP text with specific description and discussion addressing all required items for stormwater pollution prevention, as outlined in the construction SWPPP Checklist, available at the following link: http://www.adeq.state.az.us/environ/water/permits/download/cswppp.pdf. Ensure a copy of the Arizona Pollutant Discharge Elimination System (AZPDES) General Permit is included in the text and ensure each submittal contains a signed copy of the Notice of Intent (NOI) as submitted to Arizona Department of Environmental Quality (ADEQ). The SWPPP should be consistent with the Site and Grading plans and drainage report. Listed below are some items that must be included with a resubmittal. Please visit the links provided for complete SWPPP preparation/requirements. 1. Provide the project operator's name and project information. 2. Provide a copy or copies of signed owner/operator certifications with the resubmittal. 3. Depict and label an appropriate washout location. 4. Depict and label a sediment trap or basin (optional). 5. Depict and label an appropriate protected material storage area. ยท For information regarding SWPPP content specifications, go to: http://www.azdeq.gov/function/forms/appswater.html Resubmittal will require a revised Drainage Report, Site, Grading and Stormwater Pollution Prevention Plans addressing all items listed above. Please enclose "red/green lines" with the resubmittal package for reference.
