Page 3 May 8, 1990 11. 12. Grading/Drainage The grading plan shows a floor elevation for the proposed building of 884 and the centerline of the street at an elevation of 886.33. City Code requires that the building elevation be at least 18 inches above the street. This may be modified provided there is good drainage from the building. The grading plan shows the drainage from the northeast corner of the parking lot flowing north to the Sunfish Lake Boulevard ditch with minimal fall. We would recommend that the building be raised or the drainage pattern changed to provide better drainage from this area. Landscape Plan The landscape plan illustrates a mixed foundation planting with plants roughly 10' on center. Selection of plant materials is not well suited for the north side of the building and should be revised with material more tolerant to shade/north exposure. The boulevard planting should be enhanced with more canopy trees. Silver maple are not acceptable as boulevard trees due to their soft wood, size and susceptibility to storm damage. These trees should be replaced with a suitable hardwood species and spacing should be reduced to approximately 40' On the south side of the building, the five foot setback to pavement provides little room for screening loading dock activity without using a fence. The plan indicates alternate use of pine and Lindens. The pine normally get to be 20-30' across at the base and will encroach into the truck maneuvering area as well as the lot to the south. Greater consideration should be given to treatment of this building side due to its high visibility. One alternative would be to construct a landscaped curb island extending south from the east line of the building. Ail disturbed areas not sodded will need to be seeded.
