5.3. A residence has been placed on a site as illus- trated in Figure 5.29. Using the finished floor elevations noted on the plan, regrade the site and indicate all proposed contour lines and spot elevations. The proposed exterior grades adjacent to the building cannot be less than 0.5 ft nor more than 1.0 ft below the estab- lished FFE, except at the garage door. 1. .
