Miscellaneous: Catch basin #1 should have a solid lid. A section from the north side of the site to the suuth side of the site passing through the middle of both wetlands, L•he wetpond, and the inlet and outlet from ti.� wetland system sliould be provided (section C as drawn in on sheet C-3). The existing ground elevations, proposed elevations, th•� normal high water elevations in the wetlands, inverts �f pipes, etc., should be shown. The elevation of the outte: pipe relative to the existing ground elevation shculd be made very clear. If the proposed locatian of the outlet pipe is downstream of the local high point controlling the water elevation in the wetland, the pipe invert should be set at the existing ground elevation. However, if the controlling point is located downstream of the proposed pipe inlet location, and will be eliminated by the construction of the south entrance, the elevation of the pipe invert must be set at the elevation of the downstream high point. More spot elevations are needed along the south driveway/ entrance. The site plan and the grading/drainage plan are not consistent with each other in terms of the swale location and access to the wetpond at the northern end of the pond - the grading plan does not show a wetpond access or a swale. A plan for restoration of any areas that will be disturbed by the construction of stormwater facilities (e.g. swales, wetpond, storm drains, etc.) will be required to be approved by the Planning Dapartment prior to the disturbance. A specially designated area will be required for washing of cars by tenants of the complex. The area must be hydro- logically 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 designed 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 designated area. A covenant must be recorded and signed by the owner stating that such a clause will be written into the tenant leases and/or rental agreement.s. in addition, a note stating that car washing is only permissible in the designated area must be included on the storm drainage plans. As an alternative to the specially designated car washing 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
