H&H Surveying

ESP understands the entire flood risk cycle from base data collection through effective issuance. We have a dedicated survey department for H&H surveys who have worked closely with water resource managers and hydraulic modeling engineers over the past 15 years to provide accurate survey data to streamline H&H model input.

Since 2000, ESP has performed thousands of surveys for FISs, including field survey of over 12,000 hydraulic structures, 2,400 cross sections, 1,450 high water mark surveys, 243 coastal transects, and 130,000 remote sensed first floor elevations (FFE). ESP stands ready to support the surveying needs for H&H studies. We are also equipped for surge capacity needed to respond to natural disasters, such as flood and hurricane events.
