Total stream and tributary impacts 363 3i. Comments: Of the proposed impacts, only 56 linear feet are permanent and will require mitigation at a 2:1 ratio. The temporary construction impacts are necessary for installing the box culvert and relocating the water line. An impervious dike and diversion channel is proposed (see attached Construction Sequencing) to conduct the construction activities in the dry. The proposed 103 LF of temporary dewatering is concurrent with the proposed box culvert installation. In addition, there is a UT to Boulding Branch located on the south side of the proposed bridge replacement that will be temporarily impacted with dewatering in order to install the proposed waterline.

Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The proposed project is to remove the existing two span structure and replace it with a double, reinforced, concrete box culvert. Roadway approach work is minimized as much as is practical to reduce the overall project footprint. Impacts to the associated protected riparian buffers has also been reduced by promoting sheet flow, out-letting drainage pipes outside the riparian buffer and proposing rip rap aprons to reduce the flow to non-erosive velocities. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Impacts will be minimized by strict enforcement of Best Management Practices for the protection of surface waters, restrictions against the staging of equipment in or adjacent to waters of the US and coordination (including a pre- construction meeting) with the Division Environmental Supervisor. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
