ENVIRONMENTAL BOARD MEETING MARCH 31, 2004 Mr. Schlichting stated that the basins had not yet been identified. There were six ponds. Asleson responded the ponds would infiltrate. Mr. Schlichting indicated that the ponds hold water two ways. They held water by lining them with clay, or because the groundwater was there. Asleson stated that it needed more sand infiltration. He indicated that Rice Creek Watershed District was going to ask for more. If they were built up they would infiltrate, and there would be enough microbes to remove particles. Mr. Black inquired if the issue could be acknowledged and addressed with Rice Creek Watershed District. The sanitary sewer depth and storm water ponding affect development of the site. Asleson answered that if the size of the lots were reduced, it would reduce the amount of infiltration required. O’Dea made a motion: We recommend denial under the present zoning. This is an excellent property to create a contiguous greenway corridor. • We recommend this development be a P.U.D. conservation development that incorporates variability in lot sizes and street widths. • Work with Saddle Club property for the two parcels to be developed concurrently. • Seasonally high groundwater table be evaluated in relation to infiltration and NURP ponds by civil engineer and the Rice Creek Watershed District engineer. • Work with staff to identify the trees that can be saved in the buffer areas. • Developer should work with staff to establish and record conservation areas with restrictions for specific lots. • Create a greenway corridor from the Southwest corner to the Southeast corner and up along the East side of the property. Grundhofer seconded the motion. Motion carried unanimously. 6. DISCUSSION ITEMS A.
