The developer should be aware that the entire site is required to be graded, including the building pads. The cross section indicates only the street will be graded--revise cross sections. 2.

Submit documentation regarding design methods used to size the detention pond. 3. Incorporate comments from Wright Soil and Water Conservation District into the plan. Utility Plan 1. Install 6 inch tile line along rear lot lines of Blocks 1 and 2, and connected to proposed storm sewer. This tile line will allow a direction connection to the sump pumps in the future homes. 2.
