Agenda Item 5A Environmental Board Meeting Date: May 25, 2005 Topic: Integra Homes -The Preserve, PUD, Conservation Development/ Preliminary Plat application review. Background: On May 25th of 2005, the Environmental Board reviewed a site purchased by Integra Homes. The purpose of review was to present the natural resource and cultural issues on the Integra Site in order to discern the viability of conservation development on the Integra land. There were no lot/street layouts that were looked at that time. Subsequently, Integra submitted application for a PUD Development on April 10, 2006 Analysis: From The Environmental Board Resources Review of May 25th 2005 /Summary Resources The Integra property is within a Level 1 habitat/greenway area of the Open Space, Greenways, Parks and Trails Plan. Level 1 habitat is those habitats pulled out of our MLCCS that are of higher existing value. The Integra property is in regionally significant eco patches. These eco - patches were mapped by the MN DNR The MLCCS for the Integra site showed: Delineated wetland areas are cattail marsh. The aspen forest area also has interspersed oaks, cherry and red maple on the more upland areas. These areas are inundated with new growth buckthorn plants. There are smaller areas of saturated aspen forest, long grasses and forbs on upland soils, willow swamp, seasonally flooded non native emergent vegetation, and grassland with sparse trees, oak forest, and wet meadow -shrub sub type. County Ditch 25 channels water to the NE through the Integra land, and goes to Wards Lake, then to Reshanau Lake. The flood plain area map is extensive throughout this site. It was recommended to do as much as possible to create a surface water treatment train and buffer system to improve water quality to Reshenau Lake.
