Figure 17: Cross Section View of Drainage and Conservation Framework <br />iv. Water Appropriation — Describe if the project proposes to appropriate surface <br />or groundwater (including dewatering). Describe the source, quantity, duration, <br />use, and purpose of the water use and if a DNR water appropriation permit is <br />required. Describe any well abandonment. If connecting to an existing <br />municipal water supply, identify the wells to be used as a water source and any <br />effects on, or required expansion of, municipal water infrastructure. Discuss <br />environmental effects from water appropriation, including an assessment of <br />the water resources available for appropriation. Discuss how the proposed <br />water use is resilient in the event of changes in total precipitation, large <br />precipitation events, drought, increased temperatures, variable surface water <br />flows and elevations, and longer growing seasons. Identify any measures to <br />avoid, minimize, or mitigate environmental effects from the water <br />appropriation. Describe contingency plans should the appropriation volume <br />increase beyond infrastructure capacity or water supply for the project <br />diminish in quantity or quality, such as reuse of water, connections with <br />another water source, or emergency connections. <br />AUAR Guidance: If the area requires new water supply wells, specific information <br />about that appropriation and its potential impacts on groundwater levels should be <br />given; if groundwater levels would be affected, any impacts resulting on other <br />resources should be addressed. <br />Dewatering <br />Construction dewatering may be required for the development of the AUAR study <br />area. No permanent dewatering is anticipated as no underground structures will be <br />constructed adjacent to a water body. Construction activities associated with <br />dewatering will include discharging into temporary sedimentation basins to reduce <br />the rate of water discharged from the site, as well as discharging to temporary <br />stormwater BMPs. Any temporary dewatering will require a DNR Temporary Water <br />Appropriations General Permit 1997-0005 if 10,000 gallons per day or 1 million <br />Lino Lakes Main Street - AUAR 49 July 2025 <br />Page 57 of 617 <br />
