Dam Break Inundation Zones

Areas represent dam break inundation zones based on individual dam/spillway designs. Development within this boundary shall be studied to determine if or how the dam’s hazard rating is effected, and the results shall be reviewed and approved by the Virginia Department of Conservation and Recreation. Developing within this boundary may raise the hazard classification of the dam and require improvements at the expense of the developer and the dam owner. The PMF ( Probable Maximum Flood) is caused by the PMP (Probable Maximum Precipitation) of 38” in 24 hours. The average precipitation for Virginia Beach is 48” per year.
