National Dam Inspection Program. Oxford Valley Mall Dam (NDS-ID Number PA-00801, DER-ID Number 9-171), Delaware River Basin, Queen Ann Creek, Bucks County, Pennsylvania. Phase I Inspection Report.
Abstract
Oxford Valley Mall Dam is a homogeneous earth embankment about 1,200 feet long. The height, measured from the top of the embankment to the toe of the impervious fill, is about 27 feet. However, fill extending from the embankment to U.S. Route 1, a distance of about 850 feet, has reduced the apparent height of the embankment to about 13 feet. The eight acre reservoir was formed by excavation to the elevation of the reservoir drain inlet. The spillway consists of an octagonal reinforced concrete intake tower, 851 feet of an eight foot wide by eight foot high conduit and a transition section at the outlet. The dam and reservoir are used to control storm water runoff from the adjacent Oxford Valley Mall. The dam and its appurtenant facilities are considered to be in generally good condition. Calculations indicate that the existing spillway system discharges about 46 percent of the Probable Maximum Flood (PMF) without overtopping. It is assessed that the embankment would probably withstand overtopping for a limited period. Therefore, the spillway system of this structure is considered to be inadequate but not seriously inadequate.
