This civil detail shows a building foundation adjacent to a surface drainage swale with a splash pad extending from the downspout. A protective liner extends five feet minimum from the building face beneath the proposed grade. Underground utilities including a proposed eight-inch storm drain, six-inch sewer, and eight-inch hydrant lateral run parallel to the swale alignment. Existing grade transitions to proposed grading matching an existing concrete gutter on the opposite side.
