Our comments on this application are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). Wild trout reproduction should not be impacted by project activities, and a trout moratorium does not apply. Impacts are associated a development on 85 acres. Stream impacts are associated with the installation of two reinforced concrete pipe (RCP) culverts. We recommend against RCP and high density polyethylene (HDPE) culverts, as these smooth materials are less likely to hold stream substrate and provide for movement of aquatic organisms like fish and salamanders. We offer the following recommendations to minimize impacts to fish and wildlife: I. In -channel work should be accomplished as quickly as possible and vigilance used in sediment and erosion control during site preparation, construction, and clean up. Disturbed areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of each work day. A native riparian seed mix and native shrubs and trees should be used to permanently stabilize disturbed stream areas. 2. Any erosion control matting used should be free of plastic or nylon mesh, as this type of mesh frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for years.

The proposed culverts are RCP material. We recommend against using RCP or HDPE material, as this material is less likely to hold stream substrate and provide for movement of aquatic organisms like fish and salamanders. 4. Effective stormwater management is essential in minimizing impacts to downstream waters. Stormwater control measures should mimic the hydrograph consistent with an impervious coverage of less than 10%. We recommend the use of Low Impact Design techniques, such as grassed swales and pervious pavement; curb and gutter, catch basins, and underground piping of stormwater should be avoided. As stormwater runoff from pavement can cause short-term temperature spikes in downstream waters, mechanisms to lower stormwater temperature should be incorporated into the stormwater management design. 5. Maintain open space areas with native vegetation. Thank you for the opportunity to review and comment on this project.
