County Launches Flood Risk Study Map Application

The Rockland County Planning Department’s Geographic Information System (GIS) team has implemented an interactive map application that enables residents to view their property in relation to flood risk, the county executive has announced.

The GIS team, with the assistance of the Rockland County Office of Fire and Emergency Services, has developed the Preliminary FEMA Flood Risk Study Map Application, in tandem with the Federal Emergency Management Agency’s (FEMA’s) Rockland County Flood Hazard Mapping Update project. The interactive map application is located on the Rockland County GIS Portal, which can be accessed from the Rockland County GIS link on the County website at

This interactive map allows a user to determine if their parcel may be in the preliminary 100-year flood plain, or if it is slated for removal from the current 100-year flood plain within the process of the review and digitization of the FEMA Flood Insurance Rate Maps (FIRMs).

“Rockland County has made a commitment to provide an effective, user-friendly way for citizens, businesses and local governments to access valuable GIS-related resources,” said County Executive C. Scott Vanderhoef. “The launch of this application helps us expand that commitment by providing residents with a way to view the FEMA mapping update process, as well as to review their flood risk.”

“We are very excited about the release of this new application,” said Douglas Schuetz, Director of GIS. “The direct access it provides residents to the FEMA mapping update is important, and we are proud to be able to continue improving the accessibility of vital data like this to Rockland residents.”

As part of FEMA’s Flood Hazard Mapping Update project, Rockland County’s FIRM has been revised to reflect new data and converted to a digital format so residents, homeowners, business owners and officials can better understand their flood risk and manage development.
