Specifications include, but are not limited to: STRUCTURE (2-12' X 9' RCBC) & APPROACH GRADING. This project crosses a stream inhabited by the Topeka Shiner, a federally endangered species. The following conditions shall be implemented to minimize the impact of stream crossing construction on the Topeka shiner. Failure to implement the following conditions may result in violation of the Endangered Species Act. Construction activities within the stream, along the stream banks, and in areas that drain into the stream will not be allowed unless comprehensive and effective Best Management Practices (BMPs), that will prevent sediment, fuels, chemicals, concrete wash water, and other pollutants from entering into the stream, are in-place and functioning properly. Erosion and sediment controls shall be maintained in good working condition until vegetation is restored to 70% of the pre-disturbance condition. Erosion and sediment controls implemented shall be those appropriate for the specific site conditions. Fill material shall not be placed below the ordinary high water elevation except as directed by the plans or as allowed by the United States Army Corps of Engineers 404 permit.
