The project engineer should consider replacing the rookery along the northeast edge of the pond with a retaining wall. The City has observed poor performance of rockeries in this situation, with water ponding at the rockery base. If a rockery will be provided, the setback distances shown on the attached sketch must be met. The fire de1�artment typically requests 10 feet of flat ground around the perimeter of buildings. Adequate horizontal room is also import.�nt in allowing maintenance of buildings. The recreation building and building B are too close t•.o the wetpond. Sufficient topography must be shown on adjacent properties, particularly in the areas of the swale and the wetpond, to show that the proposed grading is feasible - proposed contours must be shown to "meet up with" those contours on adjacent property. The ultimate dis�:harge location of the existing concrete pipe that this p�:oject discharges into should be shown on the plans. If there is any question as to the adequacy of this system to convey storm flows from this project, an analysis of the system will be requi�ed to be performed and submitted. A specially designated area will be required for waehing of cars by tenants of the complex. The area must be hydro- loqically isolated from the rest of the site, be covered, and washwater from the area must drain to the sanitary sewer � after being routed through a baffle-type oil/water separator desiqned to City standards. Signs must be posted on the site limiting car washing to the designated area only. The tenant lease or rental agreement must contain a clause prohibiting car washing on the site outside of the specially ' deaignated area. A covenant must be recorde:d and signed by the owner stating that such a clause will �e written into the tenant leases and/or rental agreements. In addition, a note stating that car washing is only permiesible in the designated area must be included on the storm drainage plans. As an alternative to the specially designated car washinq area, hose bibs can be eliminated from the site or tenant access to them prevented. If this option is exercised, the tenant lease or rental agreement must contain a clause prohibiting car washing on the site. A covenant must be recorded and signed by the owner stating that such a clause will �e written into the tenant leases and/or rental agreements. In addition, a note stating that car washinc; is prohibited on the site must be added on the storm drainage plans. I
