Project Impact Technical Study


City of Rye, NY - Project ImpactThe City of Rye is located on Long Island Sound in Westchester County, New York, approximately 7 miles north of the New York City line. It is bordered on the west by the Village of Mamaroneck, on the north by the Village of Rye Brook, on the northwest by the Town/Village of Harrison, and on the northeast by the Village of Port Chester. Long Island Sound forms the City’s southern and eastern boundaries. Rye is a small residential community of 15,000 people, with single-family homes occupying 60 percent of its 6 square miles. Less than 10 percent of the City is in commercial use: Campus-type office buildings that are headquarters for businesses and corporations are the main large economic enterprises in the community; the central business district consists of about 200 small businesses that serve local residents.

In 1998, the City of Rye was designated a Project Impact community by the Federal Emergency Management Agency. The purpose of Project Impact is to build disaster-resistant communities through private and public sector partnerships. As a result of its shoreline and watershed position, Rye experiences chronic flooding and wind damage from coastal and inland storm events. Flooding causes repetitive property losses; as a result, approximately 500 residents hold federal flood insurance policies.

As part of Project Impact, the City is working closely with the New York State Emergency Management Office (SEMO), the Westchester County Emergency Management Office and Chamber of Commerce, and major private corporations, including Consolidated Edison, Inc. to improve its disaster preparedness. FEMA, through its Hazard Mitigation Grant Program, has provided substantial funds to improve a local breakwater and the pier at Westchester County’s Playland Park. The City also has initiated several flood mitigation projects addressing erosion control, elevation and relocation of structures, and stream bank improvements, and has partnered with more than a dozen local businesses and community organizations to enhance disaster response.


The Technical Study component of Project Impact will provide a comprehensive watershed database to identify and implement the structural and institutional measures needed to create a disaster-resistant community.

The City of Rye occupies the shore of Long Island Sound and the lower reaches of the Blind Brook and Beaver Swamp Brook watersheds; both basins are tributary to Long Island Sound. In addition to the City of Rye, the Blind Brook watershed contains portions of the Village of Rye Brook, the Town/Village of Harrison, the City of White Plains and the Village of Port Chester. In addition to Rye, the Beaver Swamp Brook watershed contains portions of the Town/Village of Harrison and the Village of Mamaroneck; the west branch of the Beaver Swamp Brook is entirely within the Town/Village of Harrison and is known as Brentwood Brook or Beaver Swamp Brook West.

Rye is located in the Hudson Valley climatological division in New York State. The average annual precipitation is 49 inches.


The Project Study Area will comprise the Blind Brook and Beaver Swamp-Brentwood Brook watersheds for purposes of developing the stormwater management models and GIS databases. The Project Study Area will emphasize the watershed area within the incorporated boundaries of the City of Rye for purposes of developing project outputs and performing selected surveys; however, flood control solutions that benefit the City should be presented regardless of watershed position.


The City of Rye, New York, in cooperation with the Federal Emergency Management Agency (FEMA), will soon be seeking proposals from a qualified consultant, or team of consultants, to prepare a comprehensive GIS-based technical study to identify actions needed to create a flood-resistant community and improve stormwater quality. Specifically, the technical study will develop comprehensive hydrologic and hydraulic models for the Blind Brook and Beaver Swamp Brook watersheds to update the Federal Flood Insurance Study maps for the City, and to identify flooding and water quality problems and solutions.

The study will emphasize environmentally feasible flood control initiatives that minimize or eliminate repetitive property losses. Such initiatives may include acquiring land and easements to prevent increased flooding, reclaiming wetlands, and modifying or constructing new stormwater structures. The study also will stress improving the quality of interior waterways and the receiving waters of Long Island Sound.

Related field surveys and GIS-based inventories will be prepared to inform the modeling effort, facilitate implementation of stormwater management projects, and support the emergency planning objectives of Project Impact. The City of Rye also intends to use the technical study to apply for FEMA Hazard Mitigation Grants and to support future applications for Clean Water Act water quality funding.
