SUBJECT: Tucson Water Southern Avra Valley Storage And Recovery Project (SAVSARP) Recharge Facilities Grading Plan Engineering Review
ADDRESSS: 2984 South Sandario Road, north of Snyder Hill Road
LOCATION: T14S, R11E, Sections 22, 27-29, 32-34
REVIEWER: Elizabeth Eberbach, PE
FLOODPLAIN STATUS: FIRM Panels: 04019C2175K and 040192200K (effective date 2/8/99), SFHA zones: A01, A02, & A03.
ACTIVITY NUMBERS: T07BU01318, T07CM02493 - T07CM02501

SUMMARY: DSD Engineering Division has reviewed the plan set submittal for Grading Plan review, and recommends a conditional approval of the grading permit with conditions. The drainage report was reviewed for the initial phase of the Tucson Water SAVSARP recharge basin project only.

GRADING PERMIT CONDITIONS:
1) Admin.Dir.1.07-6.III.A: The following 5 conditions apply to grading permit T07BU01318:
a) This permit is for the initial phase of the Tucson Water SAVSARP recharge basin project only.
b) The Southern Avra Valley Storage And Recovery Project (SAVSARP) Recharge Facilities and Raw Water Delivery Pipeline (CIP Nos.W339 and W439) plans are a part of the grading permit. See also Floodplain Drainage Analysis Report for Southern Avra Valley Storage and Recovery Project (SAVSARP) by TetraTech dated 09/20/06 and Addendum dated 05/14/07, engineering response letters dated May 31, 2007, June 5, 2007, CH2MHILL Geotechnical Design Report dated 7/12/06, ERR dated June 2007, and Tucson Water Plan No.9-062-2006 and specifications.
c) Benchmark and datum information is provided on sheet G-9 of the Grading Plan set.
d) All proposed structures for this project shall be set at a minimum of 1-foot above the jurisdictional water surface elevation as shown on the approved plans and drainage report.
e) Submit a copy of the as-builts to the City of Tucson Development Services Department upon completion.
f) The remaining signatures for the operators on Certification Statements on sheet G-10 must be on the site copy of the Stormwater Pollution Prevention Plan (SWPPP) at, or before, commencement of construction. At minimum, one operator, either the engineer of record or the project manager shall sign the certification.
g) The following conditions shall be completed prior to commencement of any earthwork activities:
i) Prior to commencement of any earthwork activities, provide copy of the report for the levee maintenance plan that provides discussion of how the levee structures shall be maintained, including identification and procedure for maintenance inspection and schedule. The maintenance plan shall include an assessment as to whether Levee B shall be upgraded.
ii) Prior to commencement of any earthwork activities, a copy of the updated SWPPP, with a copy of General Permit, showing on planview locations of the proposed stabilization practices / interim erosion control methods shall be submitted to the City of Tucson Development Services Department Engineering Division. The updated SWPPP shall have the registrant's seal on sheets G-10 through G13 of the SWPP. The SWPP shall clearly delineate disturbance area / limits of grading.
2) DS Sec.10-02.2.3.1.2.F: All conditions of Pima County Regional Flood Control District Floodplain Use Permit No.07-438 approved 6/7/07 shall apply.
3) DS Sec.11-01.4.1.C: Additional grading and floodplain review by the City of Tucson Development Services Department will be required for permits for the future booster station structure. At the time when permits are required for the booster station, it will be determined whether Levee B will need to be upgraded. For the booster station permit review, submit grading plans, updated SWPPP, and a drainage report that includes:
a) WSEL's adjacent to the proposed structure.
b) Finished building elevation at a minimum of one foot above the regulatory floodplain water surface elevation.
c) Discussion of stormwater velocities at booster station building pad and extents of any needed erosion protection so that the Tucson Water booster station site will be protected from 100- year floodplain scour and erosion.
d) Discussion of the levee structure to protect the booster station or other intent. Any levee proposed to be recognized as a permanent structure by FEMA needs to show conformance with NFIP section 65.10(b-e) including erosion protection, seepage, settlement, and other levee design criteria, as well as operation, maintenance, and certification plans. Include an assessment as to whether Levee B shall be upgraded.
e) Tucson Code Sec. 26-8(a)(2)b: Provide discussion regarding how the booster station will be: constructed so as to minimize or eliminate flood damage; constructed to minimize or eliminate flood and erosion damage; designed with strict conformance to the public's health, safety and welfare; and evaluated to prevent any contamination of the groundwater aquifer.
f) DS Sec.11-01.4.1.C: Grading plan shall show delineation for disturbance area / limits of grading; shall provide local benchmark on plan view and datum information relative to the floodplain data; shall clarify extents of erosion protection; shall show erosion protection for Tucson Water site so that their site will be protected from floodplain scour and erosion; and shall provide estimates for cut/fill and for total disturbance area in square feet.
4) For gas lines and any other utilities, contact the utility company for coordinating grading construction.
5) Submit two half size copies of the approved plan sets to the City of Tucson Development Services Department Engineering Division.

If you have any questions, call me at 837-4934.
