A case study of a recent master plan for a 16. 5 sq mi watershed in Virginia Beach, Virginia is presented to illustrate stormwater master planning approaches. The analysis showed that public perceptions of increases in fluvial flooding potential were unfounded, and that coastal storm surges cause more flooding in the impacted area than fluvial flooding under an ultimate land use scenario. Final recommendations were to prevent development and prohibit filling activities in the floodplain. Approximately 1 million worth of improvements which were originally proposed for the study area were found to be ineffective and environmentally harmful by the master plan study.
