Adelaide Landing Residential Development EAW, Hugo January 31, 2017 City of Hugo Rules: Stormwater Management Plans, Erosion and Sediment Control Plans, Wetland Alteration, and Floodplain Alterations. The City of Hugo is the local governing unit for these sections of the Rice Creek Watershed District Rules. Water resources within the project area may also be regulated under: Section 404 and 401 of the Federal Clean Water Act administered by the U.S. Army Corps of Engineers and the Minnesota Pollution Control Agency, and Minnesota Statute 103G.245, administered by the Minnesota Department of Natural Resources (DNR). Impacts to wetlands to accommodate road crossings are anticipated to have only minor effects, if any, to the host watershed. Most of these impacts are proposed along somewhat linear drainage features that will be crossed with culverts. The project proposer evaluated alternatives as the site was designed to avoid and minimized impacts, and will further analyze opportunities for reductions as required through the Wetland Conservation Act sequencing process. Compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed, to the degree practicable. There are six Corps - approved wetland banks within the same major watershed, but only three of which fall within the pre -settlement zone (<50%). There are numerous additional banks and credits available within the same wetland Bank Service Area (BSA-7). The project proposer is also evaluating opportunities to potentially restore some of the on -site wetlands for replacement credits. b) Other surface waters- Describe any anticipated physical effects or alterations to surface water features (lakes, streams, ponds, intermittent channels, county/judicial ditches) such as draining, filling, permanent inundation, dredging, diking, stream diversion, impoundment, aquatic plant removal and riparian alteration. Discuss direct and indirect environmental effects from physical modification of water features. Identify measures to avoid, minimize, or mitigate environmental effects to surface water features, including in -water Best Management Practices that are proposed to avoid or minimize turbidity/sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage. Anticipated physical effects and alterations to surface water features are discussed in 11 iv. Direct effects to the project will include fill to accommodate the internal street network, ponds, and few residential lots; indirect effects are not anticipated. As discussed, unavoidable impacts, as determined through the wetland permitting process, will be compensated via purchase of offsite banking credits, or on -site replacement. The required wetland permitting process will fully evaluate opportunities to further avoid, minimize, and mitigate environmental effects to surface water features on the site. In - water Best Management Practices to avoid or minimize turbidity/sedimentation while physically altering the drainages and wetlands (such as silt fence, bio rolls and silt booms) will be described in the project SWPPP, and deployed as needed. The project site does not encompass surface waters that are used by watercraft, and therefore will not change the number or type of watercraft on any waterbody. 23
