P76. Prepare Storm Water Data Report

A Storm Water Data Report is required for all project phases. It is a toll used to identify, evaluate and document the best storm water management plan for each project. Substantial information and procedures regarding Storm Water Management for PID’s is found in Section 5 of the Storm Water Project Planning and Design Guide (PPDG). A short form Storm Water Data Report (SWDR) or a full Storm Water Data Report must be completed for all projects. The SWDR and the corresponding checklists are found in Appendix E of the PPDG. The project engineer is responsible for initiation of the SWDR and for obtaining the involvement of other units towards its completion. General guidance for storm water cost estimates is available in the PPDG, Appendix F.

The SWDR summarizes the information found in Checklists SW-1, SW-2 and SW-3. Checklist SW-1 lists categories of pertinent information required for storm water planning and design. Checklist SW-2 provides a guide to collecting information relevant to project storm water quality issues. Checklist SW-3 provides direction to the designer during the project-planning phase to avoid or reduce potential storm water impacts.

The SWDR and all of the corresponding Checklists are initiated during the PID process, updated during the PA/ED process and updated again and completed during the PS&E process. During each process, the SWDR is signed by the project engineer, District Design Storm Water Coordinator, the designated Landscape Representative, designated Maintenance Representative, and by the project manager to verify that storm water quality design issues have been addressed and the data are complete, current and accurate. At the conclusion of project design, the project engineer stamp is required and the report is to be included in the final PS&E package.

The purpose of the SWDR is to document the key information regarding the selection and evaluation of Design Pollution Prevention Best Management Practices (BMPs), Treatment BMPs and some Temporary Construction Site BMPs. It is also used to document key negotiated understandings or agreements with the Regional Water Quality Control Board (RWQCB) pertaining to the project.

Time Constraint:

Once it is determined that a Short Form - Storm Water Data Report is appropriate, it should not take more than a day to complete. If a full SWDR is needed, the time to complete it will vary depending on the size and complexity of the project. The gathering of information will actually span the entire PID process. The signatures for the SWDR are needed before the circulation of the Draft PID because the cover sheet (with signatures) should be an attachment to the Draft PID.
