• A loggerhead shrike survey maybe required by the DNR as part of a development project if tree or shrub disturbance would be planned during the nesting season. 12. Physical Impacts on Water Resources. Will the project involve the physical or hydrologic alteration (dredging, filling, stream diversion, outfall structure, diking, and impoundment) of any surface waters such as a lake, pond, wetland, stream or drainage ditch? ®Yes ^ No If yes, identify water resource affected. Describe alternatives considered and proposed mitigation measures to minimize impacts. Give the DNR Protected Waters Inventory (PWI) number(s) if the water resources affected are on the PWI. Wetland Impact: No specific development plans have been developed for the study area. Both state and federal wetland regulations require avoidance and minimization of-wetland impact. However, with anticipated infrastructure needed to serve the study area such as roads and utilities, it is anticipated some wetland impact would occur. Approximately 1-3 acres of wetland impact for each scenario could be anticipated as part of development in the study area. Wetland impact would be subject to State regulations through the Wetland Conservation Act (WCA) and by the City's Wetland Ordinance. The City is the Local Government Unit (LGU) for the WCA. Impacts would also be regulated by the US Corps of Engineers through Section 404 of the Clean Water Act. Wetland impact would need to be avoided and minimized to the greatest extend practical. The wetland complex in the north provides a more contiguous connection to wetlands and natural areas outside of the study area and could be incorporated into a larger wetland mitigation and stormwater management plan for the study area. Impact on Public Waters: There are no DNR Public Waters/Wetlands within the study area as shown on Figure 11-1. The Mississippi River (a DNR Watercourse) is adjacent to the study area. No DNR Public Waters would be impacted by any of the development scenarios. 13. Water Use. Will the project involve installation or abandonment of any water ' wells, connection to or changes in any public water supply or appropriation of any ground or surface water- (including dewatering)? ®Yes ^ No If yes, as applicable, give location and purpose of any new wells; public supply affected, changes to be made, and water .quantities to be used; the source, duration, quantity and purpose of any appropriations; and unique well numbers and DNR appropriation permit numbers, if known. Identify any existing and new wells on the site map. If there are no wells known on site, explain methodology used to determine.
