TRANSMITTAL DATE: June 27, 2012

DEVELOPMENT PLAN COMMENTS: Please resubmit revised drawings along a response letter, which states how all Zoning Review Section comments regarding the Land Use Code and Development Standards were addressed.

1. This development package was reviewed for full code compliance with the City of Tucson Development Standards (D.S.) and Land Use Code (LUC) for the entire site.

2. It appears that a portion of this proposed Renewable Energy Generation is located within the RX-1 zone. If this is the case per LUC Section 2.3.2.3.C Renewable Energy Generation "38", subject to: Sec. 3.5.11.2.B., C., D., and E. and approval through a Zoning Examiner Full Notice Procedure, Sec. 23A-50 and 23A-53, requires a Special Exception. Until comment 12 is addressed the requirement for the Special Exception cannot be verified. If a Special Exception is required the development package cannot be approved until the Special Exception is approved. If the Special Exception is required and approved provide the case number, date of approval, and any conditions of approval on the cover sheet of the development package.

The following comments are based on the "LAYOUT TO BE USED WITH A DEVELOPMENT PACKAGE SUBMITTAL (DS 2-01) dated 12-2009. This layout document can be viewed @ http://cms3.tucsonaz.gov/files/dsd/DevPackageSubmittalLayout.pdf;

3. The sheet order is not correct. All general notes are to be on the cover sheet or a sheet following the cover sheet, organized under a heading indicating which plan the note(s) are for, i.e. site, grading, etc. The Native Plant Preservation plan should follow the Landscape plans.

The following comments are based on Development Standard 2-01.0:

5. D.S. 2-01.3.2.D Zoning acknowledges that D.S. 2-01.3.2.D states that an administrative street address is to be provided in the title block. After discussion with Pima County Addressing the administrative street address is to be provided adjacent to the title block. That said provide an administrative address adjacent to the title block.

6. D.S. 2-01.3.3 Provide the following relevant case numbers on the plan adjacent to the title block on all sheets, DP12-0085

7. D.S. 2-01.3.4 Provide a location map that meets the requirements of D.S. 2-01.3.4.

8. D.S. 2-01.3.5 When the development package documents consists of more than one (1) sheet, a sheet index (a legible drawing of the site showing the area represented on each sheet) is to be placed on the cover sheet or the second sheet, see comment 4.

SUBJECT: Prairie Fire SOLON TEP Solar Project Engineering Review
ADDRESS: 7540 S OLD VAIL RD
LOCATION: T15S, R15E, Section 21
REVIEWER: Elizabeth Leibold
CASE: DP12-0085

SUMMARY: PDSD Engineering Division has reviewed the Development Package for the Prairie Fire Solar Project and recommends conditional approval. Project is impacted by the Rita Ranch Master Drainage Report and associated annexation Ordinance 6143. For this solar project, a SWPPP and Floodplain Use Permit application will be needed for resubmittal.

CONDITIONS OF APPROVAL:
1) DS Sec.2-01.3.8.F: Address the following clarifications in the Drainage Report:
a) DS Sec.10-01.2.1: Add to the report that the project is within the Julian Wash Watershed which is a Balanced Basin Management Watershed.
b) DS Sec.10-01.2.2: Clarify detention & retention requirements in report by addressing the following comments:
i) Per the Rita Ranch Master Drainage Report, the Rita Ranch Regional Detention Basin allows for 190 cfs allocated for runoff to this regional basin from an 28.9 acre site to the north of this regional basin. State that the project does not exceed this requirement.
ii) State that the project does not need to provide detention or retention for the watershed that enters the Regional Basin per the Rita Ranch Master Drainage Report.
c) State whether the downstream condition, on the north side of the project, increases Q100 leaving the site on the north side for proposed conditions.
2) DS Sec.2-01.3.8.I: Address the following drainage comments on the plans:
a) Label on planview for site and grading plan sheets, the following information:
i) floodplain information, including the location of the developed condition 100-year flood limits for all flows of 100 cfs or more with 100-year flood water surface elevations; and
ii) water surface contours for existing floodplain areas for the 100-year flood with water surface elevations; and
iii) W.A.S.H. Ordinance watercourse label offsite on planviews; and
iv) W.A.S.H. Ordinance 50-ft Setback line within property limits.
b) DS Sec.10-01.3.5.1.3.a: Hydrologic soil type D is indicated on soils maps which typically do not provide for basin drain down times meeting City standards of under 12 hours. Provide an orifice plate for the 12-in bleed pipe for basin and show on detail PD01 on sheet 7.
c) Per the Rita Ranch Master Drainage Report, drainage easements may be needed, including maintenance access easement for the Rita Ranch Regional Detention Basin. Unless there is another access easement from Valencia Road, provide by delineation and labeling, an access easement across a portion of access area for Public Drainage Maintenance Access, from northeast access easement to south corner of project along proposed access road. Provide the recordation sequence number information on plan view. Provide gate opening at this corner of the project.
3) DS Sec.2-01.3.7.A.7: The property is subject to annexation requirements; provide the applicable annexation file number, in the lower right corner of each sheet. List the applicable conditions of approval as a note. Development Plan with Landscape Plan & Grading Plan is required per Annexation. Provision and participation in the improvement district for maintaining public infrastructure is also referenced in the Annexation (Ord.6143). The City has not yet determined if a provision will be imposed for this project.
4) Address the following note comments on the cover sheet:
a) Clarify Basis of Bearing and Basis of Elevation. Elevation with datum should be provided that matches drainage report and/or provide explanation of datum. Rotated boundary data is confusing; clarify/explain or correct boundary data to match title report and/or ALTA - provide one or the other with resubmittal.
b) DS Sec.2-01.3.7.B.1: Drainage Notes. List the following notes under Drainage Notes This project is affected by the City of Tucson Floodplain Regulations. A floodplain use permit is required for the project.
5) DS Sec.11-01.4.C: Address the following grading related comments:
a) LUC Sec.3.7.2.7: Disturbed areas are required to be reseeded as stated in previous meetings. Show and label and add as notes that there will be reseeding for all disturbed areas for this project to the following plans: LA-01, General Grading Note on sheet 7, Sheet 4, and cover sheet.
b) Tucson Code Chap.26 Art.2: On sheet 7, Detail GD03 shows built up fill against silt fence - this is not acceptable due to concentrated flows that would occur for this design. Provide standard drain rock (which is typically also not feasible or used) or show that ground is flattened to allow stormwater to actually flow through the silt fence as the silt fence is intended to do.
c) For inspection purposes, provide several dimensions for basin, and outlet channel structure on plan view sheet 4.
d) Label rock size and thickness (min 2 D50) for detail PD02.

For resubmittal, to show compliance for conditional approval, provide 2 sets of plans, 2 copies of reports or other documentation, and a response letter. If you have any questions, call me at 837-4934.
