| 01/09/2008 | LAITH ALSHAMI | ENGINEERING | REVIEW | Denied | Laith Alshami, Engineering and floodplain Review, 01/15/2008 Pavilion at Civano Grading Plan Comments: 1- Provide a copy of the Tentative Plat. Please be advised that the grading plan shall be approved only after the tentative plat is approved. 2- The approval of the proposed Lots 9 and 10 grading requires an approved development for these two lots. Submit development plans for the said lots 9 and 10 prior to the resubmittal of the grading plan. 3- The plan shall be clearly marked "GRADING PLAN". 4- Provide the T07BU02480 case number in the Tile Block. 5- Use the T07PI00023 (PIA number) as a reference only. 6- Include the CDRC Case number in the Title Block. 7- Revise the Title Block to clarify that the submitted grading plan is only for the installation of the private access roads and the proposed detention basin and the associated drainage structures, and the rough grading of Lots 9 and 10. The plan title implies that the grading plan is for the entire site improvements. 8- Provide the administrative address. 9- Add a general note concerning blue staking the project before construction activities start. 10- Show and label grading limits. Include the grading limits symbol in the legend. 11- Add the following general notes: a. The approved Grading Plan is the only acceptable construction plan onsite. The Contractor may not use any other plans, such as the approved Tentative Plat and/or Development Plan, for construction purposes. The Contractor may ask the Development Services Inspector to consult with the other approved plans for additional information or details that might not be included on the approved grading plan but needed for completion of work. b. The contractor shall remove the fine materials from the bottom of the detention/retention basin and scarify the basin bottom once the construction activities are completed in order to remove any fine material build up caused by construction and to restore soil percolation. The contractor may, alternatively, install BMP's at the basin inlet(s) to prevent fine materials from entering the basin and clogging the basin bottom. c. Add a note, which states that any engineering work to be done below grade (i.e. toe-downs, cutoff walls, drainage pipes/structures, etc.) shall not be back filled until Development Services Inspector inspects the work and approves it. d. The contractor is not permitted to make an autonomous decision to carry out construction field changes without prior written approval from the Engineer of Record and the City of Tucson Development Services Department. e. CALL FOR SWPPP INSPECTION AND PRE-CONSTRUCTION MEETINGS. FOR A DSD ENGINEERING INSPECTIONS, CALL IVR (740-6970), OR SCHEDULE WITH A CUSTOMER SERVICE REPRESENTATIVE AT THE DEVELOPMENT SERVICES DEPARTMENT, OR CONTACT DSD ENGINEERING AT 791-5550 EXTENSION 2101, OR SCHEDULE INSPECTIONS ONLINE AT: http://WWW.CI.TUCSON.AZ.US/DSD/ONLINE_SERVICES/ONLINE_PERMITS/ONLINE_PERMITS.HTML. f. The project will be in compliance with City of Tucson Development Standard 11-01.0 (Excavation and Grading). g. A copy of the approved Grading Plan, Grading Permit, and any Geotechnical Reports shall be kept at the site at all times, until final grading approval. h. Any revision to the Grading Plan MAY require a re-submittal of a revised grading plan for review. Contact DSD Engineering at 791-5550 to discuss changes in grading design. i. If grading construction is expected to last longer than the expiration date of the grading permit, contact DSD to renew/extend the Grading Permit. If Final Grading Inspection has not been completed before the Grading Permit expires, and the permit has not been renewed, additional fees and reviews may be required. j. See the associated Stormwater Pollution Prevention Plan as a part of this grading permit. k. Contact Permits and Codes at 791-5100 for any questions regarding any right-of-way permit requirements. l. As-builts and letters of completion for basin and overall project are required. m. The Engineer of Record shall submit a statement of conformance to as-built plan and the specifications. n. The permitee shall notify the DSD when the grading operation is ready for final grading inspection. Final grading approval shall not be given until all work, including installation of all drainage facilities and their permanent protective devices, and all erosion control measures have been completed in accordance with the approved grading plan and grading permit, and any required reports have been submitted. o. Depress all landscaped areas a maximum of 6" for waterharvesting" 12- Show the location of cross-section detail A/3 on the plan. Additionally, show the sidewalk dimension on the detail A/3. 13- Show the location of the thickened edge pavement detail on the plan. Additionally, clarify why the ABC thickness in the thickened edge detail is thicker than the ABC thickness in Detail A/3. 14- The weir toe down, shown in Detail D/3, can not be dumped riprap, which does not provide the required protection. Propose more durable material such as concrete or grouted riprap. 15- Show on Sheet 1/7 the basis of elevation and the basis of bearing and the tie to the subject development. 16- Clarify what the solid lines with the letters "F" and "C" signify. 17- Clarify how the existing and created slopes (cut or fill) shall be protected and stabilized. Provide a Geotechnical Report that addresses slope stabilization and protection 18- Provide additional detention basin construction information (i.e. dimensions, curve radii, additional cross-sections, etc.). 19- The detention basin appears to require a sediment trap to minimize bottom sedimentation and help reduce the need for maintenance. 20- It appears that the detention basin outlet will be partly within Lot 1. Clarify how the maintenance responsibility will be shared by different lot owners. 21- Are the detention basin and its inlet channel going to be within a common area or a drainage easement? 22- The Bottom of the basin does not appear to provide the proper positive drainage and the 1% slope appears to be inaccurate. Either provide a low flow channel or revise the bottom slope to provide acceptable positive drainage in accordance with the requirements of the Detention/Retention Manual. 23- It appears that the velocity in the basin inlet channel is erosive and will require channel protection and erosion control at the discharge point within the basin. Provide a revised drainage report that addresses this issue and the sediment trap. 24- Work in the public right of way requires an excavation permit and/or a private improvement agreement. Check with City of Tucson Department of Transportation Permits and Codes for additional information. 25- Ensure that the proposed landscaping in the detention/retention basins does not conflict with the basin's inlets/outlets and maintenance ramps. 26- Resubmit the redlined plan with future Grading Plan submittals. 27- Provide a detailed response letter with the next submittal that explains how the comments were addressed and references the exact locations/sheets where the revisions were made. SWPPP Comments: 1. Show the grading limits on the SWPPP exhibit. 2. Place controls inside grading limits. 3. It appears that the proposed work Drexel and Houghton Roads shall be included in the SWPPP. Please be advised that the stabilized entrances may need to be relocated based on this comment. 4. Show, on Figure 2, the washout area and BMP's around the box culvert wing walls and the detention basin slopes including its inlet channel, the construction trailer and all high and low points. Please be advised that washout area must not be within the detention basins and the washout runoff shall not be drained into the basins. 5. Identify the name of nearest receiving waters and the areal extent and description of any wetlands that will be disturbed or receive discharges from disturbed areas of the project. (Part IV.C.4) 6. Identify all operators for the project site, and the areas over which each operator has control. Provide the operators (Part IV.C.1). 7. Indicate in the SWPPP the name(s) of the party(ies) with operational control over project specifications (including the ability to make modifications in specifications). (Part IV.B.2.c). 8. Indicate in the SWPPP the areas of the project where the operator has operational control over project specifications, including the ability to make modifications in specifications. (Part IV.B.1.b). 9. Indicate in the SWPPP the name(s) of the party(ies) with day-to-day operational control of those activities necessary to ensure compliance with the SWPPP or other permit conditions. Provide a table for recording the names and responsibilities for each party responsible for activities necessary to ensure compliance with the SWPPP or other permit conditions. (Part IV.B.1.d). 10. Indicate in the SWPPP the areas of the project where each operator has operational control over day-to-day activities. (Part IV.B.2.c). 11. Include a certification and signature for each operator in accordance with Part VII.K. (Part IV.J.1). 12. Provide completed and signed NOI for all known operators and some blank forms for the unknown operators. (Part IV.F) Each operator is responsible for submitting a completed NOI to ADEQ and to the City of Tucson. 13. Identify location and potential discharges from support activities, including asphalt/concrete plants and stockpiles if applicable. (Part IV.C.5). 14. The Certification Section shall be signed and dated. 15. Section "IV.B.2." states that the Site Map should show the approximate post-grading slopes, locations of waste, borrow, fill, equipment storage, or offsite material, but Figure 2 does appear to provide this information. Revise. 16. In the "Sequence of Major Construction Activities", the first activity shall be marking the grading limits on the ground and installing the grading limit fences before the BMP's are installed inside the grading limits. Revise the section accordingly. 17. Provide in the report a copy of the AZPDES Construction General Permit. 18. Describe structural practices to divert flows from exposed soils, store flows or otherwise limit runoff and the discharge of pollutants from exposed areas of the site to the degree attainable. Placement of structural practices in floodplains shall be avoided to the degree attainable. A combination of sediment and erosion control measures is required to achieve maximum pollutant removal. 19. Elaborate on how non-stormwater discharges will be filtered using BMP's in accordance with the requirements of Part IV.D.7. and Part IV.D.8. a, b, c, d, and e.
