National Dam Inspection Program. Village Two at New Hope Dam (NDI ID PA-00803, PA DER 9-173), Delaware River Basin, Unnamed Tributary of Delaware River, Pennsylvania. Phase Inspection Report
Village Two at New Hope Dam is a zoned earth embankment approximately 300 feet long with a maximum height of 34 feet which impounds a reservoir with a normal pool storage capacity of 14 acre-feet. The normal overflow spillway consists of a 36-inch diameter steel riser pipe, 21 feet long, feeding into a 30-inch diameter steel pipe through the base of the embankment which outlets downstream of the dam. The emergency overflow spillway consists of a reinforced concrete overflow inlet structure and a 48-inch diameter reinforced concrete discharge pipe constructed through the dam and outletting on the downstream abutment close to the downstream embankment face. The dam is located at New Hope, Pennsylvania, about 0.25 miles west of the Delaware Canal. The Spillway Design Flood (SDF) chosen for this 'Small' size, 'High' hazard dam is 50 percent of the Probable Maximum Flood (PMF). The spillways are capable of discharging 29 percent of the PMF without overtopping of the embankment. However, a dam breach with 50 percent of the PMF will only increase the water surface elevation at the downstream hazard area by 0.9 feet. Therefore, the spillways are classified as 'Inadequate', but not 'Seriously Inadequate'. Based on the visual observations and review of the information obtained Village Two at New Hope Dam is considered to be in fair condition. The following recommendations and remedial measures should be initiated immediately. The Owner should retain the services of a licensed professional engineer experienced in the design and construction of dams to assist in complying with these recommendations and remedial measures.
