• Agenda Item 5A Environmental Board Meeting Date: August 28, 2002 Topic: Ray Benkler, Lake Drive, CUP and Site Plan Review Background: Application to build a car wash and rapid oil- change was submitted for property on Lake Drive. This property is on the West Side of Lake Drive, East of the new elementary school, North of Don's Auto, and west of the Methodist Church (Attachment 1). A proposed Site and Utility Plan (Attachment 2), Grading Plan (Attachment 3), and Landscaping and Tree Preservation Plan (Attachment 4), were submitted and are enclosed with this report. The site is 1.56 acres. The site is zoned Light Industrial District. The allowable impervious area is 90 %. Sewer and water will service the site. There is no surface water or soils information available at this time. There is no Rice Creek Watershed District information at this time. Soils on this site are mostly sandy and hydric (Attachment 5). Soils are also indicated to be very sensitive to ground water contamination in the Anoka County Sandplane Groundwater Study. The submitted design directs surface water through infiltration basins and infiltration swales to a larger infiltration basin on the West Side of the property. The top of this basin berm is 0.3 feet above the indicated seasonally high water elevation. All overflow water from this basin would flow to basins adjacent to the schools (Attachment 6). Infiltration swales indicate a 1.0 % slope. Curbing on the Southeast corner is designed as flat, if needed. The Lino Lakes Handbook for Environmental Design identifies this area as a Lake Protection Zone (Attachment 7) and several High Ecological Value Zones (Attachment 8) are in close proximity to the site. High Ecological Protection Zones are area where ecological protection opportunities are very high and that protection of these values should be a foremost consideration in the development process. The Lake Protection zone consists of waterbodies, wetlands and parks that are protected from development under current regulatory controls. Under protection status, no development should occur. Trees on the site consist entirely of recently developed and opportunistic types ( Boxelder) of trees growing on a largely disturbed site (Attachment 9). The MLCCS describes this area as boxelder /green ash forest with 11% to 25% impervious cover. Immediately adjacent to this area are areas that are seasonally flooded, have other exposed transitional land with 0 -10% cover and a weedy waste, and short grasses with 51 -75% impervious cover. Trees are proposed for removal to accommodate building and basin construction. •
