The quality of existing stormwater runoff from the project is typical of agricultural land. <br />Stormwater runoff flows from upland areas to lower elevations on site as sheet flow where it <br />generally gets conveyed into either Cedar or Wilkinson Lake. <br />Up to approximately 60 acres of land are expected to be impacted during construction. A <br />Stormwater Pollution Prevention Plan (SWPPP) will be developed for the project to ensure <br />protection of water resources during construction. Due to the adjacent Wilkinson Lake, an <br />impaired water, the special provisions for impaired waters included within the Minnesota <br />Construction Stormwater General Permit will be included within the SWPPP. Temporary erosion <br />and sediment control best management practices (BMPs) will initially be installed (per the project's <br />SWPPP), maintained/repaired, and amended throughout the construction phases as required to <br />remain compliant with the applicant's NPDES Construction Stormwater Permit. BMPs may include <br />(but are not limited to) silt fence, bio-rolls/filter logs, rock construction entrances, mulch/hydro <br />mulch, and permanent native seeding or turf seeding in appropriate areas. <br />The quality of storm water runoff from the project post construction will be typical of an urban land <br />use with impervious surfaces and lawn/landscaping generally generating higher concentrations of <br />total suspended solids and total phosphorus. Stormwater runoff is proposed to be conveyed into <br />permanent constructed stormwater treatment infrastructure (e.g. infiltration basins, filtration <br />basins, holding ponds, vegetated swales, etc.) across the site for treatment prior to discharge. <br />These features will be designed to reduce flows to receiving waters and to accommodate for the <br />increased precipitation projected to occur based on climate trends. Flow reductions will be <br />calculated and included within the required storm water management permits. <br />iii. Water appropriation - Describe if the project proposes to appropriate surface or <br />groundwater (including dewatering). Describe the source, quantity, duration, use and <br />purpose of the water use and if a DNR water appropriation permit is required. Describe any <br />well abandonment. If connecting to an existing municipal water supply, identify the wells to <br />be used as a water source and any effects on, or required expansion of, municipal water <br />infrastructure. Discuss environmental effects from water appropriation, including an <br />assessment of the water resources available for appropriation. Discuss how the proposed <br />water use is resilient in the event of changes in total precipitation, large precipitation events, <br />drought, increased temperatures, variable surface water flows and elevations, and longer <br />growing seasons. Identify any measures to avoid, minimize, or mitigate environmental <br />effects from the water appropriation. Describe contingency plans should the appropriation <br />volume increase beyond infrastructure capacity or water supply for the project diminish in <br />quantity or quality, such as reuse of water, connections with another water source, or <br />emergency connections. <br />No appropriations of surface waters are proposed as part of the Project. Water will be sourced <br />from the City of Lino Lakes's existing public water supply system (PWS # 1020023) and/or the White <br />Bear Township existing public water supply system (PWS # 1620025). The Lino Lakes PWS is <br />currently sourced from five groundwater wells (MDH #s 240171, 559373, 554207, 722629, and <br />767887). Construction of new watermains will be required to service the project.. The projected <br />water demand for the site is an average flow rate per capita of 88,800 gallons per day with a peak <br />flow rate per capita of 199,700 gallons per day. <br />Page 17 <br />
