Twelve of the soils (AnA, AnB, AnC, Bm, Bx, D20A, Mc,NrD, Rf,ZmC, ZmD,NyQ have limitations due to factors such as ponding, depth to saturated zone, shrink-swell, frost action, and slope. Grading operations for residential development construction are expected to affect about 115 acres and involve movement of about 400,000-500,000 cubic yards of soil to construct streets,residential building pads, and stormwater features. Elevations in the project area range from 904 feet above mean sea level at the highest point in the northwestern part of the site to 864 feet at the lowest point in the southeastern part of the site. 9
