LARKIN, HOFFMAN, DALY & LINDGREN, LTD. Mr. Steven R. Sarkozy Thomas M. Scott, Esq. May 28, 1999 Page 11 The existing south buffer zone along Ryan Avenue is about 40 to 45 feet wide from the property line to the existing shopping center parking. It, too, is ,generally defmed by a six-foot high vine-covered chain link fence. The south buffer area contains a mix of overstory coniferous (12 spruce trees), overstory deciduous (10 ash, linden, or olive trees) and large shrubs (19 lilac) in mature sizes similar to the east buffer. The south buffer also provides very good screening of the parking area. As shown on Exhibit D, a new stormwater treatment pond is proposed for the southeast corner of the site. This pond eliminates some existing parking adjacent to the residential areas and provides additional green buffer area. An existing trail will be relocated about 200 feet to the west of its present location at the westerly end of the pond. This design avoids encroachment on the east buffer area. The proposed stormwater treatment pond will require a partial fence relocation and removal of about three spruce trees adjacent to Ryan Avenue. Cub Foods proposes to replant vines on the relocated chain link fence and plant a dense row of 16 spruce trees within the upland buffer area between the pond and Ryan Avenue. The existing west buffer area adjacent to the rear of residential lots along Asbury Street is about 70 feet deep. Similar to the other buffer zones, a heavily vine-covered six-foot high chain link fence and a mix of mature coniferous trees (21 overstory spruce), deciduous trees (24 overstory trees) and large shrubs (21 lilac) provide a good visual screen for the adjacent residential area. Proposed new plantings in the west buffer zone include ten additional overstory coniferous and one additional deciduous tree. Three overstory deciduous trees would also be added in a new planting area within the parking for the northerly drive aisle. Upon completion of the proposed landscape plan, the total number of existing trees or shrubs and new trees and shrubs in the three Har Mar buffer zones will be: east buffer-169; south buffer-57; west buffer-77. . Grading and Drainage Stormwater runoff from the existing Home Place site drains by surface flow to two small, dry detention basins located on the east side of the building near the dock area. The existing basins provide little if any water quality treatment and do not meet current City and Rice Creek Watershed District criteria. The north basin has a tributary area of 0.78 acre and the south basin has a tributary area of 6.76 acres. Stormwater runoff which enters the two basins is discharged by outlet structures to an existing 48-inch storm sewer. Both existing dry detention basins will be filled in to provide additional parking and driving surface, or green area for the proposed Cub Foods store. Stormwater runoff from areas tributary to the north basin will now be conveyed directly to the existing 48-inch storm sewer by a system of new catch basins and pipes. Stormwater runoff from areas tributary to the south
