Based on past use and permitted capacity, the <br />existing municipal wells have sufficient surplus capacity to serve the proposed project. A trunk water <br />main will be extended from Riverdale Drive to serve the development area. Water flow, pressure, <br />and storage will be adequate to serve the development area. As indicated under Item 11.a.ii, the <br />project is not located in or near a wellhead protection area. <br />iv.Surface Waters <br />a)Wetlands.Describe any anticipated physical effects or alterations to wetland features such as <br />draining, filling, permanent inundation, dredging and vegetative removal. Discuss direct and <br />indirect environmental effects from physical modification of wetlands, including the anticipated <br />effects that any proposed wetland alterations may have to the host watershed. Identify measures <br />to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental <br />effects to wetlands. Discuss whether any required compensatory wetland mitigation for <br />unavoidable wetland impacts will occur in the same minor or major watershed, and identify <br />those probable locations. <br />As discussed under Item 11.a.i., the project area does not include any surface waters, wetlands, <br />streams, or channels. <br />Wetlands and waters near the project areaaregenerallyregulated by the Lower Rum River <br />Watershed Management Organization(LRRWMO), which administers the Minnesota Wetland <br />Conservation Act (WCA)in the project area; the U.S. Army Corps of Engineers(USACE), which <br />administers Section 404 of the Federal Clean Water Act(CWA); and the MPCA, which administers <br />Minnesota water quality standards and Section 401 of CWA. <br />The projectwill not involve physical effects on or alterations of any surface waters, wetlands, <br />streams, or channels. <br />17 <br /> <br />
