Content:
st total extent in the vicinity and a discussion of the relative importance of habitat types lost based on functions (e.g., importance to wildlife). • Description of any plans for restoration (e.g., grading, contouring, seeding, and planting) of temporarily disturbed terrestrial habitats and an estimate of the time required for restored habitats to regain pre-disturbance conditions and functionality. • Determination of whether excavation or other site-preparation activities might substantially dewater wetlands or surface waterbodies (e.g., ponds, springs, and seepages) or alter surface drainage patterns in a way that might affect terrestrial biota and a discussion of possible impacts to affected habitats and wildlife. DG-4026, Page 65 Wetlands Information on wetland impacts should be as consistent as possible with Federal, State, and local wetland permit applications, and possible discrepancies should be explained. Wetland permit applications are sometimes prepared subsequent to the ER; in such cases wetland impact data presented in the ER should be conservative enough to account for likely impact levels ultimately reported in permit applications. The ER should also include information on unregulated wetland impacts, including impacts to wetlands not under regulatory jurisdiction. The ER should include the following: • Estimated disturbance footprint overlaid onto the wetland maps developed for Chapter 2. • Tables estimating wetland impacts using a widely recognized wetland classification system (e.g., the National Wetlands Inventory). Separate data should be provided for each wetland classification and each category of impact (e.g., permanent fill, temporary fill, permanent dredging, and temporary dredging). Separate tables should also be provided for the site and for each offsite parcel or corridor. • Discussion of wetland impacts and their effect on the functions and values of wetlands. • Discussion of construction BMPs that may be used to protect
