| 10/24/2007 | JASON GREEN | ENGINEERING | REVIEW | Denied | DATE: October 29, 2007 SUBJECT: 5140 S Nogales Hwy Site/Grading Plan- Engineering Review TO: Manny Delgado LOCATION: T15S R13E Sec01 Ward 5 REVIEWERS: Jason Green, CFM ACTIVITY: T07CM03690 (Site Plan) and T07BU01928 (Grading Plan) SUMMARY: Engineering Division of Development Services Department has received and reviewed the site plan (T07CM03690), grading plan (T07BU01928), and Drainage Report (Coronado Engineering and Development, 20AUG07) for the above referenced property. Engineering Division does not recommend approval of the site plan, grading plan or Drainage Report at this time. The following items need to be addressed: SITE PLAN COMMENTS: 1) DS Sec.2-02.2.1.A.8: Revise the site plan to label the 2.5-foot width for the wheel stops in plan view or reference detail 1/C3 with a keynote for construction purposes. 2) DS Sec.2-02.2.1.A.8: Revise the handicap space width dimensions shown in plan view to meet the minimum width requirements for handicap spaces. The width shown in plan view does not match detail 1/C3, clarify. 3) DS Sec.2-02.2.1.A.8: Revise the site plan to provide all dimensions for the proposed back-up spurs, specifically the 3-foot radius must be labeled and dimensioned. Refer to DS Sec.3-05.2.2.D for clarification. 4) DS Sec.2-02.2.1.A.11: Verify and label the 25-feet radii and concrete curbs per City of Tucson Transportation Access Management Guidelines (TAMG), Section 5.5 at the driveway entrance located on Nogales Highway. Refer to DS Sec.3-01.3.2.C for street development standards. 5) DS Sec.2-02.2.1.A.12: Revise the site plan to show the required 6-foot wide sidewalk with curb along the street frontage of Nogales Hwy. Per the adopted Mayor and Counsel policy all sidewalks along MS&R right-of-ways for arterial and collector streets require 6-foot wide sidewalks. If a sidewalk is existing along the street frontage provide photo documentation showing that the sidewalk is in good condition and is not buckled or cracked in spots, if the sidewalk is not in good condition then a new 6-foot sidewalk will be required. 6) DS Sec.2-02.2.1.A.12: Revise the handicap ramp detail on the site plan to show the proper handicap ramp required for the PAAL ingress/egress from Nogales Hwy. Per COT Standard detail 207 the alternative detail that is shown on the top half of Sheet 4 of 5 is the correct handicap ramp required for this location. Provide all dimension for the ramp and verify that the revision meets the design requirements per ANSI Standards A117.1-2003 Section 406.13. 7) DS Sec.2-02.2.1.A.12: Revise the site plan to label and dimension the required 5-foot sidewalk that is required between the building and the proposed PAAL. Pedestrian circulation must provide a clear 4-foot minimum width unless adjacent to a PAAL which would require a 5-foot width. In front of the overhead doors the pedestrian access can be a striped crosswalk area. Provide a handicap ramp with truncated domes where the striped area meets the sidewalk. The indicated 4' sidewalk area does not meet this requirement. 8) DS Sec.2-02.2.1.A.12: Revise the site plan to show that all existing and proposed handicap access ramps meet the design requirements per ANSI Standards A117.1-2003 Section 406.13. Provide details or keynotes that label truncated domes at all transitions from pedestrian circulation to vehicular circulation. Specifically the truncated domes for the handicap ramps must be revised to be correctly shown. 9) DS Sec.2-02.2.1.A.14: Provide (label and dimension) the required onsite maneuvering areas for the required loading zone that is shown on the site plan. Refer to AASHTO for the national standards for turning radii. All radii must be shown to scale. 10) DS Sec.2-02.2.1.A.15: Revise detail 2/C4 to show the bottom elevation and water surface elevation for the proposed basin. 11) DS Sec.2-02.2.1.A.15: Revise the basin design or provide verification that the proposed retaining walls for the basins do not occupy more than 35% of the basin side slope. If more than 35% of the side slope for the basin is constructed out of retaining walls the excess area must provide an alternate design that meets the basin configuration standards, such as a retaining wall system design that provides positive drainage away from the retaining system where an earthen slope is constructed on the inside of the basin wall to prevent ponding of water along the retaining wall. Verify that the basin still meets the retention threshold volume requirements. Provide a geotechnical report that addresses slope stability, soils conditions and setback of building to the proposed basins, refer to the geotechnical comments within this letter. 12) DS Sec.2-02.2.1.A.16: Revise the site plan to show roof drainage, with flow arrows, and down spout locations. Provide a detail for the dimension of the proposed scuppers that are used for collecting onsite roof drainage at all pedestrian sidewalk. Any scuppers proposed under the sidewalk will be designed and constructed to convey the 10-year flood flow. Provide a revised drainage report showing scupper calculations that demonstrate that the 10-year flood flow is contained under the sidewalk. 13) DS Sec.2-02.2.1.A.16: Provide the Improvement Plan reference for all existing catch basins and storm drains located along Nogales Highway. All existing drainage improvements must be shown on the site plan and must have the referenced improvement plan for site verification. 14) DS Sec.2-02.2.1.A.19: Provide a letter of approval from Arizona Department of Transportation for the proposed site plan and for all proposed construction within the state right-of-way. Contact Donna M Jones, Senior Permit Technician for ADOT review of the site plan. DJones2@azdot.gov or (520)-388-4236. 15) DS Sec.2-02.2.1.A.19: Provide the recordation information for Nogales Highway that is shown on the site plan. Label Nogales as public or private. 16) DS Sec.2-02.2.1.A.19: Provide the recordation information for the existing right-of-way. Clearly label and dimension the required 9-foot setback area from the future curb to the future right-of-way for the location of the future 6-foot sidewalk and required space. 17) DS Sec.2-01.2.1.A.20: Verify that all existing and proposed easements are drawn with recordation information, location, width, and purpose of on the site plan. Specifically for the sewer line that is shown on the site plan. 18) DS Sec.2-02.2.1.A.23: Revise the site plan to provide more spot elevations to show horizontal grading limits. Revise the bench mark reference section to include the datum reference for all spot elevations, i.e. NGVD29 or NAVD88. 19) DS Sec.2-02.2.1.A.27: Revise keynote #6 to reference the wall details that are shown on sheets C3 and C4. 20) DS Sec.2-02.2.1.A.32: Revise the Trash Enclosure Detail on Sheet C4. Provide the minimum inside clear dimension of 10 feet by 10 feet between steel pipes that are required between the container and the enclosure's rear and sidewall. Refer to the attached Figure 3 per DS Sec.6-01 for the required refuse enclosure dimensions and construction. 21) DS Sec.2-02.2.1.A.32: Revise the refuse container location to show the maneuverability to scale for the required 36-foot and 50-foot radii. When scaled the maneuverability shows that the refuse vehicle has to back up over the pedestrian access, which is not acceptable. Provide maneuverability for the enclosure to show the required 14-foot by 40-foot clear approach. Refer to DS Sec.6-01 for all refuse requirements. GRADING PLAN COMMENTS: The project was reviewed for grading plan purposes, however until all site plan and Drainage Report comments are addressed the grading plan could not be shown to be in conformance with an approved plan. 22) DS Sec.11-01.9: Revise the grading plan to provide the required 2-feet setback from the all property boundaries to the top of fill slope or retaining wall system for the proposed basins. Provide and/or revise the cross-sections on the grading plan to show the limits of grading, property lines and the required 2-feet setback from the property lines for the retention basins along the property boundaries. 23) 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. 24) DS Sec.10-02.2.3.1.6.4.a: Provide a cross section for the proposed wall openings to show all dimensions (width, height, spacing, etc.) for construction purposes. The detail must be shown on the site/grading plan and must reference all elevations and details within the drainage report. All details and cross section shown on the grading plan must be clear and precise for construction purposes. 25) Revise the basin cross sections to show the location and depth of all utilities (water and electric) that are proposed to be constructed through the basins. Verify that the utility lines are deep enough to prevent damage or water infiltration. 26) 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 27) DS Sec.11-01: Provide general grading notes, including a grading/drainage note specifying conformance with City of Tucson Development Standard 11-01.0 (excavation and grading requirements). 28) DS Sec.10-02.14.3.2: Provide a note on the grading plan stating that, (a) the owner or owners shall be solely responsible for operation, maintenance, and liability for drainage structures and detention/retention 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". 29) Please ensure that any future grading plan will be consistent with the site plan, Drainage Report and geotechnical report. Grading standards may be accessed at: http://www.ci.tucson.az.us/dsd/DevStandsTOC.pdf 30) 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. Contact Thad Harvison, (520)-791-5100 or Thad.Harvison@tucsonaz.gov for all right-of-way requirements and permit applications. GEOTECHNICAL REPORT: 31) DS Sec.10-01.III.3.5.1.3.a, 10-02.14.2.6: Provide a geotechnical report evaluation that addresses the following: a) Soils report should provide conformance with DS Section 10-02.14.2.6 regarding 30-foot boring for the basins, and provide a discussion of the potential for hydro-collapsible soils.
