Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The applicant has designed the proposed residential sub -division to avoid other impact to streams, wetlands. The applicant has selected the stream crossing locations in an area the stream is narrow and straight with few meanders. The applicant designed the road crossing the utilize approximate 7-8-foot head/end walls thus reducing the permanent impacts to streams and wetlands. Initial designs included an additional stream crossing of Muddy Creek. However, the applicant revised the overall site plan to avoid and minimize impacts to streams and wetlands by removing this crossing from the proposed design. The remaining 3.75 acres of wetlands and 8,553 linear feet of stream channel are being avoided. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The clearing limits will be staked and silt fence or other BMPs will be used. Temporary coffer dams will be installed. During construction, water will be bypassed around the construction footprints. Appropriate stream bank protection will be provided in the channel during construction and all excess excavated material will be immediately removed from the crossing area and stockpiled in upland locations. Upon completion of the culvert/sewer line installations, the temporary sand bag coffer dams will be removed and flow will be diverted through the culvert or over the restored stream beds. Following installation of the culvert and sewer lines, areas of temporary stream or wetland impacts will be restored to similar pre -construction grades. The stream banks will be matted with biodegradable materials and seeded/live staked with native species. The wetlands will be stabilized with native grass herbaceous seed mix. 2.
