• Agenda Item 5A Environmental Board Meeting Date: May 25, 2005 Topic: Integra Homes, Proposed Development Site, Resources Review and Recommendations Background: Integra Homes has purchased property South of Birch Park for Development Reasons. Please see Location Map (Attachment 1). The purpose of this report is 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 are no lot/street layouts that will be looked at this time. Attachment 2 shows the vicinity of Integra to Foxburough. Recall that the Saddle Club proposal was denied, but offered us substantial greenway/ resource protection /open space consideration. The area highlighted on Attachment 1 is approximately 50 acres. Analysis: • Resources • The Integra property is within a Level 1 habitat/Greenway (Attachment 3) area of the Open Space, Greenways, Parks and Trails Plan adopted last year. Level 1 habitat are those habitats pulled out of our MLCCS that are of higher existing value. Attachments 4 and 5 are regionally significant eco patches (expanded and close views). The close view shows Integra's land within a higher classified significant eco patch. Attachment 6 shows the MLCCS for the Integra site. 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 forbes on upland soils, willow swamp, seasonally flooded non native emergent vegetation, grassland with sparse trees, oak forest, and wet meadow - shrub sub type. Attachment 7 maps the sub watershed for the site, surface water flow, and flood plain. 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. If possible, we should be looking for ways to restore CD 25 to more of a natural system in order to restore native vegetation
