Comments:

1. The grading plan has been reviewed by Zoning Review Section but cannot approve the plan until it has been approved by the Engineering, and Landscape Review Sections and until all zoning comments or concerns have been addressed.

2. Zoning could not verify that the grading plan was in compliance with the approved site plan. Please submit two copies of the approved and stamped site, landscape, and NPPO plans with the next grading plan submittal.

3. Zoning will re-review the grading plan on the next submittal to ensure compliance with the approved and stamped site plan. Additional comments may be forthcoming.

SUBJECT: Site Plan and Grading Plan Lot 176- 2nd Engineering Review
TO: Baker and Associates Engineering, Inc.
LOCATION: 2111 E Valencia Road; T15S R14E Sec08, Ward 5
REVIEWERS: Jason Green, CFM
ACTIVITY: T06CM06322 (Site Plan) and T06BU02936 (Grading Plan)


SUMMARY: Engineering Division of Development Services Department has received and reviewed the revised site plan (T06CM06322), grading plan (T06BU02936), drainage report (prepared by Baker and Associates Engineering, Inc., dated 1-25-2007), and Geotechnical Evaluation (prepared by Western Technology, dated 11-08-06) for the above referenced property. Engineering Division does not recommend approval of the site plan or grading plan at this time. The following items need to be addressed:


SITE PLAN COMMENTS:

1) DS Sec.2-02.2.1.A.8: Provide dimensions for all 2-way PAALs shown on the site plan. Verify that the central parking area PAALs have a minimum 17-foot wide access per the Motor Vehicle Area Dimension Table in DS Sec.3-05.

2) DS Sec.2-02.2.1.A.20: It is acknowledge that the 1-foot no access easement is in the recordation process, the docket and page of the easement must be shown on the site plan prior to approval.


GRADING PLAN COMMENTS: Be advised that the grading plan can not be approved prior to site plan approval. All comments associated with the site plan must be corrected and the site plan must be approved prior to grading plan approval.

3) DS Sec.10-01.4.3.1: For this project, there may be a potential for integrity of the proposed pavement and building foundation to be undermined from the potential saturation with this type of flood restraining system. The design does not meet the technical requirements and guidelines for basin design. Revise Detail # 8 and the retaining wall system proposed. Design will not be accepted due to various engineering considerations including the potential leaking and failure of the system from break down of grout and the decay of the wall over time from poor maintenance, erosion, permeability issues and collapsibility of soils in any combination flood restraining, soil retaining systems. DSD Engineering will accept alternate designs that meet 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."

4) DS Sec.11-01.4.1.C.3: Provide the percent slope in the bottom of the detention/retention basin that is to be achieved by grading. All basins must be designed to allow positive drainage to the required low flow bleeder pipe and the outlet of the basin.

5) DS Sec.11-01.9: Revise Detail # 6 on Sheet 1 to verify that the footer of the proposed wall meets the minimum 2-foot setback from the property line. Provide sufficient room on the site plan and grading plan for the construction of the footer and wall and to allow for the 2-feet setback from property line.


STORMWATER POLLUTION PREVENTION PLAN: The SWPPP does not meet the minimum requirements of the AzPDES Construction General Permit (CGP). Revise the SWPPP according to the following comment:

6) CGP Part IV.C.3: Revise the exhibit to show the approximate location for all truck washout areas. Clarify if there is sufficient volume within the wash out area to accommodate day to day operations. The truck wash out area is to be located to prevent non-stormwater discharge from draining into proposed detention/retention basin.

7) CGP Part IV.C.3.b: Revise the SWPPP exhibit to show SWPPP controls around the outlet of the proposed detention/retention basin.

8) CGP Part IV.D.8.b: Clarify on the exhibit that both entrances point on the west side of the project for Valencia Road and Weiding Road are blocked off and will not be used for construction vehicles access.

9) CGP Part IV.J.1: The Operator must sign the SWPPP.

10) Revise Detail # 2 on the exhibit to remove the statement for the "5' additional right-of-way…" from plan view. This has been addressed on the revised site plan.

11) Revise Detail # 3 to call out the correct dimension for the proposed wall and curb openings.


GENERAL COMMENTS:

Please provide a revised site plan, a revised grading plan and a revised SWPPP that address the comments provided above. Include a comprehensive response letter addressing in detail responses to all of the above comments.

Further comments may be generated upon resubmittal of the site plan, grading plan, and SWPPP. Please enclose "redlines" with the resubmittal package for reference.
