Civil engineering scope depends on the site: grading permit (required by most Wasatch Front municipalities for cut-and-fill exceeding ~50 cubic yards or 2-foot grade changes — requires a grading plan by a licensed engineer); stormwater management (projects disturbing over 1 acre require a Utah Construction General Permit under NPDES, which includes a Stormwater Pollution Prevention Plan, SWPPP); retaining walls over 4 feet (structural/civil engineering for the wall and drainage system); and new access drives on steep lots with significant grading. Hillside lots in Sandy, Draper, and foothill communities frequently trigger multiple civil engineering requirements simultaneously — grading permit, drainage design, retaining wall engineering, and erosion control planning. RainFire Builders identifies civil engineering requirements at the site analysis stage before design begins.
