Grading/ Drainage The grading plan requires a retaining walls near the parking lot on the east side, and adjacent to Yankton on the west side of the project. The walls are approximately 3-3.5 feet high. At 36 inches, some sort of drop-off delineation should be provided. Hedges or fencing is most typical. Regardless of solution, more detail should be provided. Further, the headlights of these cars will be about 6 feet above grade at the property line. To avoid headlight issues with adjacent parcels, headlight screening is recommended. The grading will collect rain water from the parking lot and funnel it to a linear rain garden along the street. The design details of this garden have not been submitted. All drainage will be collected in a small depression on the north side of the building, then funneled to a wet bottom detention basin on the west side of Yankton. The pond will be approximately 9 feet deep at normal conditions. All storm water will need to meet the requirements of the city permit. Staff is not ready to recommend approval of the grading plan. Landscaping The landscaping plan has been prepared,but not by a landscape architect. The plan shows the minimum number of plants as required by the City Code. Staff recommends that the landscaping plan be revised, to further communicate the goals of the PUD zoning and prevent any detrimental effects on adjacent properties.
