We are pleased 10 see the appiieant has a Forest Management flan (Jane 2014) for the site and that future site plans will preserve desirable vegetation and other unique natural features when practical, Also, we are pleased to see-that stormwater collection will include low impact design and disconnecting ilarpervious surfaces 1.0 maximize stormwater infiltration, We offer file following general recommendations regarding development projects to nainin-Lize impacts to aquatic and terrestrial wildlife resources. 1. ]]"wetlands and/or streams will be impacted by construction activities, then the project should he coordinated with the U.S. Army Carps of Engineers and the N.C. Division of'1�'ater Resources. 1 Measures to avoid or minimize impacts to wetlands sho€rid be implemented during construction. In addition to providing wildlife habitat, wetland areas perform important functions of flood. control and water quality protection. 3. Maintain a minimum 100-1`00t undisturbed, native,forested buffer along perennial streams, and a mininium 50-foot:buffer along intermittent strearns and wetlands. Maintaining undisturbed, forested buffers along these areas will minimize impacts to aquatic and terrestrial wildlife resources, water duality, and aquatic habitat both within and downstream of the project area. Also, wide riparian buffers are helpful in maintaining stability of stream banks and for treatment of pol atants associated with urban stormwater. In addition, these buffers Will pr•ovidC art adequate traval corridor for wildlife species. 4. Avoid development and fill in the 100-year floodhlain. Development and fill in tire li.00dplain increases the potential for iloodin:g and i nterfcres with the natural hydrologic process of the waterways. It also disrupts the cnntir.Auity of migration corridors for wildlife. 5. Locate sewers and other utilities as far away from streams as functionally possible and minimize stream and wetland crossings. It is preferable that sewers are located outside floodplains and the riparian buffers described in##3. 6. Li.nt.it iul.pervious surface to less than 10%or use stormwater control measures to mimic the hydrograph consistent with an impervious coverage of less than 10%. 7. Use non-invasive native species and Low impact Development (LID)technology in landscaping. Using native species instead of ornamentals should reduce the need for water, fertilizers and pesticides. Using LED technology in landscaping will not only help maintain the predevelopment hydrologic regime, but also enhance the aesthetic and habitat value of the site. 8. Sediment and erosion control measures should be installed prior to any land clearing or construction. These measures slap€r.ld be routinely inspected and properly maintained. Excessive silt and sediment toads can have numerous detrim.entat effects on aquatic,resources including dVStrt1Cfl01l of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species.
