Item #01- Special Council Meeting - 01106114 File #13-3638 & 13-3639 [Total Pages 99] sediment tracking, soil stabilization, sediment traps including silt fence, and protection measures for permanent stormwater management features. iii. Water appropriation - Describe if the project proposes to appropriate surface or groundwater (including dewatering). Describe the source, quantity, duration, use and purpose of the water use and if a DNR water appropriation permit is required. Describe any well abandonment. If connecting to an existing municipal water supply, identify the wells to be used as a water source and any effects on, or required expansion of, municipal water infrastructure. Discuss environmental effects from water appropriation, including an assessment of the water resources available for appropriation. Identify any measures to avoid, minimize, or mitigate environmental effects from the water appropriation. The Project site is currently proposed to connect to city water from Minnetrista. If a water connection agreement cannot be reached between the cities of Minnetrista and Orono, then on site wells shall be used for water. Anticipated water use will be reduced when compared to the existing Golf Course site. Per the 2011 DNR water appropriation records, the golf course currently uses 20 MG of water per year. Water use is anticipated to lower by a factor of 113 when the Project site is converted to residential use combined with preservation of wetland and open space. The reduction factor includes estimated irrigation of lawns (9000 gal/week/dwelling) and dwelling water consumption (300 gal/day/dwelling). iv. Surface Waters a) Wetlands - Describe any anticipated physical effects or alterations to wetland features such as draining, falling, permanent inundation, dredging and vegetative removal. Discuss direct and indirect environmental effects from physical modification of wetlands, including the anticipated effects that any proposed wetland alterations may have to the host watershed. Identify measures to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental effects to wetlands. Discuss whether any required compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed, and identify those probable locations. The Project site will maintain all existing wetland areas where practicable. Subdivision and ROW placement will account for wetland preservation as a key factor for the development site layout. If any wetland impact is proposed, then the impact will be sequenced through the WCA LGU process. If the impact is allowed through sequencing, then replacement wetlands will be provided within the same watershed preferably within the project site boundary. b) Other surface waters- Describe any anticipated physical effects or alterations to surface water features (lakes, streams, ponds, intermittent channels, count)'/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. Little to no watercraft use currently occurs on the ponds and streams located on the Project area. Development is not expected to significantly alter watercraft use. This project is not expected to alter any existing lake littoral area, or alter existing downstream water bodies. page 8
