Enivornmental Board February 6, 2019 Page 2 APPROVED MINUTES A. Lyngblomsten Senior Living Community / PUD/ Mixed Use/ Preliminary Plat Review The concept plans for Lyngblomsten were dicussed at the February 28, 2018 and the June 21, 2018 Environmental Board meetings. The property is zoned Gerneral Business. The project proposal is located north and east of the corner of Hodgson Road and Country Road J. Lyngblomsten proposes to purchase the 17.18 acres on the northwest quadrant of the property owned by R.L. CO., LLC located at 6075 Hodgson Road, along with the insurance and liquor store buildings for the purpose of developing a senior living community and facilitating the development of a stand-alone restaurant. The plan is to create a “continuum-of-care” campus offering up to a total of 198 units comprised of a mix of independent living, assisted living, and memory care/enhanced care suites/skill nursing care plus complementary campus amenities and 20 stand-alone senior living townhomes. Land/Environmental issues have not changed. The building configurations and locations have changed, or have been defined better per this application. At this time, the application proposes to build townhomes to the north and west of the main building. According to narrative provided by the developer, these townhomes are setback from the adjacent single-family homes and existing wetlands and will preserve a significant amount of the sites mature trees, and minimize wetland impact. Surface Water and Wetlands Water runs to a constructed pond. The Watershed’s requirement is that the proposed rates of runoff cannot exceed 80% of the existing runoff rates, and the site must provide water quality treatment for 1.1 inches of runoff from the new and reconstructed impervious areas. City Engineers must verify the requirements. It appears the developer is proposing to use Stormwater for irrigation purposes as part of the volume mitigation. A wetland exists on the northwest side of the project, it is not in a wetland corridor, however the city is asking for a 25 foot buffer around this wetland. And the standard wetland buffer signs must be placed around the perimeter. The pond would need a maintenance agreement signed. We would require a plan for the establishment and management of the native prairie for a 5 year period. Usually a plan requires a fire at the end of 3-5 years, trees that would tolerate the fire are for the most part Oaks.
