PROJECT NAME: Williams Building #2
PROJECT ADDRESS: 1375 West Glenn Street
PROJECT REVIEWER: Patricia Gilbert

The following items must be revised or added to the grading plan. Please include a response letter with the next submittal that states how all comments have been addressed.

RESUBMITTAL REQUIRED: GRADING PLAN, SWPPP, GEOTECHNICAL REPORT


1. A copy of the stamped approved Site Plan must be included with the Grading Plan submittal.

2. The Site Plan is currently in review. Any changes made to the Site Plan must be reflected on the Grading Plan. The Site Plan and Grading Plan must match.

3. In the grading legend identify the contour lines weights, spot elevations for existing grades and finish grades.

4. Revise the near side SVT at the south entrance/exit drive to provide the length of the SVT to be located along the curb line. DS 2-02.2.1.A10.

5. Show on the grading plan the existing and developed 100-year discharge concentration point locations include the quantities. SMDDFM 2.3.1.6.A.

This comment is from the previous review and will remain due to the fact the localized floodplain analysis has not been provided. The discharge rate could change.

6. For basins with a water depth of two feet or more, with slopes steeper than 4 to 1. Provide a security barrier for the southeast basin. It is not clear if a security barrier is required for the other basins since the elevations can not be determined. Additional comments could be forthcoming.

The above comment is from the previous review. The response letter stated a fence has been added however a fence has not been identified on the plan. Call out the fence on the plan view.

DRAINAGE REPORT COMMENTS


1. Provide on the pre and post development site plans all points of drainage concentration for a 100-year event. Be advised this information will also need to be on the site and grading plan. Standards Manual for Drainage Design and Floodplain Management 2.3.1.3.A and B 2.b.
The above comment is from the previous review and the provide point of concentration could change based on the fact a floodplain analysis has not been provided. Once the analysis has been provided and if the Q changes revise the site plan and drainage report accordingly.

2. This project is not a mapped FEMA floodplain but the parcel lies within a City of Tucson (COT) Regulatory Flood Hazard Area. Areas with a 100-year discharge of 100 cfs or more are designated as a City of Tucson Regulatory Flood Hazard Area. The City of Tucson Floodplain Ordinance requires all structures located within a designated flood hazard area (FEMA or COT) is required to elevate one foot above the 100-year water surface elevation (WSE). Provide a floodplain analysis for the existing and future floodplain conditions for the proposed development. In the analysis provide the WSE for the 100-year event, the FFE and the datum. Refer to the Standards Manual for Drainage Design and Floodplain Management 2.3.1.4., for additional report format, content and requirements.

GEOTECHNICAL REPORT COMMENTS (Soil's Report)

1. The soil's report must show the maximum disposal times for the detention/retention facilities are being met. 12 hours is the maximum time for a detention/retention facility that intercepts runoff from an upstream watershed area that is up to ten acres in size. 24 hours is the maximum time for a detention/retention facility that intercepts runoff from an upstream watershed area that is greater than ten acres in size. Provide discussion and calculations that confirm the maximum infiltration times are being met.

2. Provide recommended setbacks from the proposed and existing structure to the underground storage facilities. It must be clear the soil type can support an underground retention system adjacent to the existing and proposed structure where the foundation is not comprised. Provide discussion and recommended setbacks for the structures.

STORMWATER POLLUTION PRVENTION PLAN COMMENTS

1. 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

2. Identify the receiving waters for this project on the location map and in the narrative (general notes).

3. The operator responsible for day to day activities (the contractor) and the operator with control over plans and specifications (owner/engineer) is required to submit an NOI to the state and a copy to the City of Tucson. Each operator is responsible for submitting a completed NOI to ADEQ and a copy to the City of Tucson. Submit two copies of the NOIs filled out and signed by the appropriate parties. (Part IV.F)

4. The Owner and Operator (1) certification statement has not been provided. Provide a certification statement for the owner and operator. Be advised this must be signed prior to approval of the SWPPP. This assures the City of Tucson prior to issuance of a grading permit that there is a designated responsible party for the SWPPP.

THE above comment is from the previous review and has not fully been addressed. It is acknowledged the certification statements have been provided however the signatures have not been provided. Provide the signatures.

5. A copy of the Arizona Pollutant Discharge Elimination System (AzPDES) General Permit must accompany the SWPPP. On the plan in a general note state a copy of the AzPDES permit provided by ADEQ will be on site with the SWPPP at all times at the construction site. A copy of the general permit can be found online at http://www.azdeq.gov/environ/water/permits/links.html
(Part IV.F)

6. Clearly indicate on the SWPPP that accumulated sediments in the retention basin will be removed prior to the planting of the required landscaping. (Part IV.D.2.b)
