Checklist SW-3, Measures for Avoiding or Reducing Potential Storm Water Impacts Prepared by: Date: District-Co-Route: PM : Project ID (or EA): RWQCB: The PE must confer with other functional units, such as Landscape Architecture, Hydraulics, Environmental, Materials, Construction and Maintenance, as needed to assess these issues. Summarize pertinent responses in Section 2 of the SWDR. Options for avoiding or reducing potential impacts during project planning include the following: Can the project be relocated or realigned to avoid/reduce impacts to receiving waters or to increase the preservation of critical (or problematic) Yes No NA areas such as floodplains, steep slopes, wetlands, and areas with erosive or unstable soil conditions? Can structures and bridges be designed or located to reduce work in live Yes No NA streams and minimize construction impacts? Can any of the following methods be utilized to minimize erosion from slopes: a. Disturbing existing slopes only when necessary? Yes No NA b. Minimizing cut and fill areas to reduce slope lengths? Yes No NA c. Incorporating retaining to reduce steepness of slopes or to Yes No NA shorten slopes? d. Acquiring right-of-way easements (such as grading easements) to Yes No NA reduce steepness of slopes? e. Avoiding soils or formations that will be particularly difficult to re- Yes No NA stabilize? f. Providing cut and fill slopes flat enough to allow re-vegetation and Yes No NA limit erosion to pre-construction rates? g. Providing benches or terraces on high cut and fill slopes to reduce Yes No NA concentration of flows? Yes No NA h. Rounding and shaping slopes to reduce concentrated flow? i. Collecting concentrated flows in stabilized drains and channels? Yes No NA Does the project design allow for the ease of maintaining all BMPs? Yes No Can the project be scheduled or phased to minimize soil-disturbing work Yes No during the rainy season?
