| 05/29/2007 | JASON GREEN | ENGINEERING | REVIEW | Denied | DATE: June 7, 2007 SUBJECT: Desert View Plaza Lot 1-7 Grading Plan- 1st Engineering Review TO: Baker and Associates Engineering, Inc. LOCATION: 6307 S Alvernon, T15S R14E Sec10, Ward 5 REVIEWERS: Jason Green, CFM ACTIVITY: T07BU00680 SUMMARY: Engineering Division of Development Services Department has received and reviewed the grading plan, Drainage Report (Baker & Associates Engineering, Inc., 22MAR07), Geotechnical Evaluation (Western Technologies, 2920JX177), Stormwater Pollution Prevention Plan (Baker & Associates Engineering, Inc., MAR07, not sealed or signed by engineer of record) and Preliminary Tentative Plat sheets for the above referenced property. Engineering Division does not recommend approval of the grading plan at this time. The following items need to be addressed: GRADING PLAN COMMENTS: Be advised that grading plan can not be approved prior to Tentative Plat approval. 1) It could not be verified if the proposed grading plan matches the last approved Tentative Plat. Provide the last approved Tentative Plat showing that the grading plan is in conformance with the Tentative Plat. The grading plan shows multiply storm drains and interim drainage channels that do not show up on the last submitted Tentative Plat. Provide a revised drainage report with discussion and hydraulic calculation sheets for all drainage improvements. 2) Provide the seal and signature of the professional engineer that prepared the plans. The grading plan must have the original seals stamped and signed on all applicable sheets prior to grading plan approval. 3) Clarify the limits of grading on the revised grading plan. Provide the parcel area and the proposed disturbance area on the grading plan along with the grading limits clearly delineated to met the requirements of phase development per the last submitted Tentative Plat. 4) DS Sec.11-01.2.3: A bond shall be posted for native seeding. If grading construction does not commence within 60 days after grubbing, the disturbed area shall be native seeded within 30 days following the expiration of the 60 day period. The reseed bond will be required at time of grading permit issuance and is based on the total disturbance area in square feet at $0.05 per squarefoot. 5) Revise the grading plan so that all work within the public right-of-way has met the requirements of Traffic Permits and Codes Department. Per conversation with Steve Tineo traffic will not accept rock riprap within the public right-of-way. Redesign the channel system so that the side slopes (and bottom if applicable) are constructed out of concrete for maintenance issues. Also an access ramp must be constructed into the channels for future maintenance access. 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 Steve Tineo at 741-3115 for all right-of-way requirements and permit applications. 6) Provide the improvement plans for all offsite storm drain or culverts systems that are within the public right-of-way and that are being used to collect onsite flows. Verify if the existing storm drains or culverts have the capacity to contain the excess flow from this development. 7) Please ensure that the Grading Plan is consistent with the Drainage Report, Geotechnical Evaluation and the last approved Tentative Plat. Grading standards may be accessed at: http://www.ci.tucson.az.us/dsd/DevStandsTOC.pdf 8) Revise the grading plan to show the required 6-foot wide sidewalk with curb along the street frontages of Valencia Road and Alvernon Way (this is based on previous meetings and conversations that was agreed to by the applicant and City of Tucson at Tentative Plat review). 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 sidewalk already exist along the frontage of Valencia Road or Alvernon Way provide photo documentation showing that the existing sidewalk is in good condition. If the sidewalk is missing in spots or is cracked and buckled a new 6-foot sidewalk will be required. 9) Revise the grading plan to show the required 5-foot wide sidewalk with curb along the street frontage of Antrim Loop. All new development requires curb and sidewalk along street frontage. 10) Revise the grading plan to show the required pedestrian circulation path that is required from all proposed buildings to the pedestrian circulation path located along Alvernon Way and Valencia Road. 11) Provide on the proposed grading plan details for all handicap access ramps. Verify that all handicap ramps at crosswalks or at the transition of a pedestrian circulation area to a vehicular use area has the required detectable warning devices (truncated domes) per ANSI Standards A117.1-2003 Section 406.13. 12) DS Sec.11-01.4.1.C.3: Provide the minimum percent slope (0.5%) in the bottom of the channels and basins that are to be achieved by grading. 13) DS Sec.11-01.4.1.C.4: The scuppers proposed under the sidewalk must 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. 14) DS Sec.11-01.9: Revise the grading plan to provide cross sections at all property boundaries to verify the required 2-feet setback from property lines to the proposed limits of grading, existing and constructed channel fill slopes, detention/retention basin fill slope and associated erosion protection have been met. Provide sufficient room to allow for the 2-feet setback from property lines to top of and toe of fill slopes. 15) DS Sec.11-01.9: Provide typical lot grading details, show minimum side and rear setbacks, and building setbacks to the detention/retention basins and constructed channels per geotechnical report recommendations. Provide detailed cross sections for each perimeter, fully labeled and dimensioned. 16) DS Sec.11-01.4.1.C.4: Provide a General Note stating that all CMU walls and retaining walls will require a separate permit for review and approval by all necessary Development Services Departments. 17) Add a general note; "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 " 18) DS 10-02.0, Section 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". 19) DS Sec.11-01.4.1.C.6: Revise the grading plan to demonstrate that the protective slopes from all proposed buildings reflect the minimum grade as recommended in the revised Geotechnical Report. Revise Grading Plan to demonstrate that the minimum horizontal setback distance from the perimeter of any building and the high-water elevation of the nearest storm-water detention/retention basin is the recommended distance per the Geotechnical Report. Clarify the areas were the proposed buildings are within the proposed setbacks of the Geotechnical Report. Or provide an addendum to the Geotechnical Report stating that the revised grading plan is acceptable. 20) The correct grading plan number (T07BU00680) may be added to the lower right hand corner of the plans where indicated by "T06BU." 21) Provide existing and future sight visibility triangles (SVTs), labeled and dimensioned, in plan view for both Valencia Road and Alvernon Way. Verify that line of sight will not be obscured between 30-inches and 6-feet through the SVT areas adjacent to the driveways or PAALs. 22) Further comments may be generated upon resubmittal of the grading plan.
