| 06/05/2008 | JASON GREEN | ENGINEERING | REVIEW | Denied | DATE: June 10, 2008 SUBJECT: Premises at Tucson Airport Grading Plan- Engineering Review TO: EEC- Attn: Ken Perry, PE LOCATION: 3649 E Corona Road, T15S R14E Sec16 Ward 5 REVIEWERS: Jason Green, CFM ACTIVITY: T08BU00622 (Grading Plan) SUMMARY: Engineering Division of Development Services Department has received and reviewed the proposed grading plan, Drainage Report (Engineering and Environmental Consultants, Inc., 30NOV07 revised 01APR08), and Geotechnical Engineering Report (Terracon, 25APR07). Engineering Division has reviewed the submitted grading plan, Drainage Report, and Geotechnical Investigation and does not recommend approval at this time. The following items need to be addressed: DRAINAGE REPORT: 1) Title 4 Chapter 30 R4-30-304.E.4: Revise the Drainage Report along with the grading plan to provide the expiration date along with the seal for the engineer of record. Per the referenced section; "All original documents should include a notation beneath the seal either written, typed, or electronically generated that provides the day, month, and year of expiration of current registration, as shown in Appendix B. (Effective 3/08/08)." 2) Revise the Drainage Report to provide a discussion on the erosion hazard setback line for the regulatory wash running through the southern portion of the property. The erosion hazard setback must be calculated for the wash and shown on the drainage exhibit, Figure 5. The calculations provided in the response letter needs to be included in a discussion within the Drainage Report, revise. 3) DS Sec.10-02.11.4.4.2: Revise the grading plan to accurately show all drainage improvements per the Drainage Report and exhibits. Provide accurate cross sections and details in plan view on the grading plan for all improvements, transitions, etc. to reflect the requirements in the Drainage Report. GRADING PLAN COMMENTS: 4) Provide a copy of an approved Tentative Plat. The grading plan will not be approved until verification that all details, locations, dimensions, and plan profiles match the approved Tentative Plat. Provide all information associated with the Tentative Plat and any additional information that is required on the grading plan that will be used as the construction document. 5) Revise Sheets 1 thru 10 to correctly label the plan set as a GRADING PLAN. Prior to grading plan approval the proposed plan set must have the words "Grading Plans for Premises at Tucson Airport……" 6) Title 4 Chapter 30 R4-30-304.E.4: Revise the grading plan sheets to provide the expiration date along with the seal for the engineer of record. Per the referenced section; "All original documents should include a notation beneath the seal either written, typed, or electronically generated that provides the day, month, and year of expiration of current registration, as shown in Appendix B. (Effective 3/08/08)." 7) See redlines on Sheets 1 thru 10 for all corrections required for the next submittal. Due to the numerous errors found on the grading plan submitted for review the following comments do not reflect all of the Quality Control comments that must be addressed prior to resubmittal. Make sure that all drainage infrastructure, dimensions, details, sections, transitions, keynotes, and all other aspects of this project meet the minimum requirements within DS Sec.3-01, 3-05, 6-01, 10-01, 10-02, and 11-01 and are reflected on the grading plan sheets. Provide comments on the redlined plan sheets that show how each comment was addressed. 8) A symbol identical to that used to represent the water surface contour intervals and the erosion hazard setback as shown on the plan should be included in the legend on Sheet 1. 9) DS Sec.3-01.3.3.A: Revise the grading plan and associated details to dimension the required 5-foot wide sidewalk along the entire street frontage of Corona Road. Refer to DS Sec.3-01 for all public curb and sidewalk requirements. 10) DS Sec.3-01.3.3.B: Revise the grading plan to show that all proposed sidewalks are constructed with the required handicap access ramps and that the ramps meet the minimum design requirements per the Standard Public Improvement Details, DS Sec.3-01.3.3.C and ANSI Standards A117.1-2003. Provide details that label and dimension the maximum slope requirements, lengths, widths, etc. 11) Revise the grading plan to show all locations and types of subdivision control monuments per the Tentative Plat, specifically at all existing and proposed property corners. Provide a clear site plan that shows the proposed 3 lots. 12) Revise the grading plan to label and delineate the proposed phase line. All proposed development for Phase 1 must be shown outside of the proposed phase line for Phase 2. All landscaping, screen walls, and right-of-way improvements that are required to be built during the Phase 1 construction must be clearly shown to be within the Phase 1 boundary line. 13) Revise the grading plan so that it is designed in accordance with Street DS Sec.3-01 and the Vehicular Use Area DS Sec.3-05. The following items need to be revised or added to the proposed Grading plan : a) Revise the Grading Plan to depict and label the minimum 18-feet radii concrete curbs returns. Curb returns are to be constructed without encroaching into the adjacent property. The end of the curb return can not encroach into a projected line from the east property line at the southeast corner of the project. Refer to DS Sec.3-01.3.2.C and the Transportation Access Management Guidelines for street development standards. For further information contact the Tucson Department of Transportation, Jose Ortiz, P.E. at 837-6730. b) Revise section C/10 on Sheet 10 to include a copy of the WWM Detail #111 or clearly show that the stabilized surface for the public easement is constructed out of the minimum design requirements per the LUC for vehicular use areas (concrete, asphalt or double shot chip seal). c) Revise the grading plan to provide the minimum width of 20-feet for fire access lanes at all PAAL and gate locations. All fire access lanes must have a minimum 20-foot width requirement, revise. d) Revise the grading plan to dimension the dump station location. Verify the minimum 24-foot width requirement for the unobstructed PAAL at this access point. Provide the dimension in plan view. e) Revise the grading plan to clearly depict the proposed 16-foot access gate at the entrance of the proposed WWM access road. f) Revise the grading plan to clearly show the type of material or method of construction for the WWM access road at the east property corner. Provide a cross section showing the slope, material used and the minimum 2-foot setback from toe of slope to property line. g) Refer to comments from Ron Brown, RA Structural Plans Examiner for all ANSI Standard requirements. 14) Revise the grading plan to include the language "by Final Plat" after all proposed easements. If the review of the plans by the respective utility companies changes the easement locations to interfere with buildings, drainage infrastructure, etc a revised grading plan will be required to correctly show locations of buildings and improvements to be outside of the easements. 15) Revise the grading plan to clearly show all proposed Private Drainage Easements and Private Access Easement per the Tentative Plat. Both the drainage easement and the access easement must be graphically depicted on the grading plan with a legal description (surveyable lines). 16) DS Sec.2-08 a continuous pedestrian circulation route must be provided from the street to the proposed storage office. Further clarification-DS 2-08.4.1 requires the sidewalk to the office to be physically separated from the PAAL - raised, curbing, etc., revise all cross section and plan view to reflect. 17) Revise the grading plan, in conjunction with the submitted Drainage Report, to reflect the following information. For additional information regarding drainage standards, see the City of Tucson Standards Manual for Drainage Design and Floodplain Management. a) Provide a detail for each individual riprap pad, weir wall, slope protection or other drainage structure showing the exact dimensions (width, length, depth, thickness, etc.), details, and elevations. The pads can be dimensioned in plan view or with a clear precise easy to read table for construction purposes. b) Provide an access ramp into all basins to meet the minimum width of 15-feet. Provide spot elevations or percent slope for the ramp to verify that it does not exceed 15 percent. Per DS Sec.10-02.14.3.4 the standard does not distinguish between a private or public basin. All basins are required to have an access ramp into them. The use of ATVs or other vehicles driving over the constructed slopes to maintain the basin is not common engineering practice due to the erosion and break down of the slope from wear and tear. c) Revise the grading plan to clarify the drainage openings in the proposed chain link fence around Basin #2. The chain link fence must be elevated at all inlet concentration points to allow water to pass through without blocking debris and trash causing adverse impacts to the property. d) Revise the grading plan to clarify the drainage openings in the proposed 6-foot screen wall around Basin #1. Provide the wall within all cross sections that apply and clarify how the wall is built over the basin inlets. Provide a profile view showing lintels or other type of construction for the wall support at the depressed curb openings or clarify how the inlets operate with the block wall constructed over them. e) Revise the grading plan and Basin #2 to show a cross section along the west property line at the northwest corner through the property line and basin side slope. A minimum 3-foot wide top of berm is required with a minimum 2-foot setback from toe of fill slope to property line. f) Revise the grading plan and Detail F on Sheet 10 to clarify the weir height per the Drainage Report. The Drainage Report calls out a 4-foot high weir wall, but the grading plan only calls out 3-feet, clarify. g) Revise the grading plan and both weir wall details to show method of construction. The detail provided is a modified detail from the Public Improvement Standards. Provide all dimensions, depth of cut off walls, thickness, etc on the detail for construction purposes. h) DS Sec.11-01.9: Revise the grading plan to provide for the required 2-feet setback from all property boundaries to the proposed limits of grading, fill slopes, retention basin, block wall and associated erosion protection. Revise all cross sections to clearly show the 2-foot setback from the property line as depicted in plan view. 18) DS Sec.6-01: Revise the grading plan to provide a detail for the proposed double trash enclosure that meets the minimum requirements of DS Sec.6-01, Figure 3. Provide an enclosure detail for both a single and a double refuse container. 19) Provide additional spot elevations for all refuse containers to verify that stormwater runoff does not pond within the enclosure areas from PAAL stormwater runoff. Very that all curb and gutter flow stays within the PAAL and does not flow into the enclosure. 20) DS Sec.11-01.9: Revise the grading plan to accurately show the direction of slope grade for the proposed 2:1 and 1.5:1 (H: V) slope along the west property line at the southwest corner of the property. The proposed slope must be correctly called out and verification of the required 2-foot setback is required. Provide a cross section through this area to verify all dimensions. 21) DS Sec.11-01.4.1.C.4: Provide a General Note stating that all fencing and walls will require a separate permit for review and approval by all necessary Development Services Departments. 22) Provide a general note on the grading plan to state the following: "Call for a Pre-construction meeting prior to start of earthwork. To schedule a DSD Pre-construction meeting, SWPPP inspection or general 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 23) Review and approval from TDOT Permits and Codes for all improvements within the public right-of-way will be required. A right-of-way use permit application will be required prior to construction.
