The applicant has submitted a rough grading plan as an integral part of the street and storm drainage improvement plans to the City for review and approval.
The grading plan must accurately show contours of the existing ground elevations and details of area drainage and terrain, including identification of areas with existing or proposed gradients greater than 33 percent. The plan must also show contours of the finished ground elevations to be achieved by the proposed grading activities plus all grading within public rights-of-way, and typical cross-sections of all proposed drainage channels and swales. Existing and proposed contours must be shown extending at least 200 feet beyond the boundaries of the development site at 2-foot intervals.
The grading plan must also comply with the new “lot-to-lot” grading standards for residential developments.
