Flood Risk Management

Bookmark and Share Email Print

DESCRIPTION:

Flooding on the Byram River primarily affects the Town of Greenwich, just south of the constructed project of levees at Pemberwick.  A secondary damage area was identified to the north, on Bailiwick Bridge within the Town of Greenwich.  This bridge is small, with low clearance, and it consequently traps debris on the river course, effectively acting as a dam.  Its stone facing was stripped by raging floodwaters during the April 2007 storm.  There are also minor tidally induced flood damages at the lower end of the Byram River within the Village of Port Chester, Westchester County, New York.

 

AUTHORIZATION:

The study was authorized by a Resolution of the House of Representatives, Committee on Transportation and Infrastructure, Docket Number 2779, dated May 2, 2007. 

 

STATUS

Byram River is one of six river basins investigated in the Reconnaissance Report for Westchester County Streams, Westchester County, NY and Fairfield County, CT (approved September 2008). Feasibility Cost Sharing Agreement (FCSA) was executed on August 29, 2012 with the Town of Greenwich, the non-Federal partner for the study.  Public information meetings were held in Town of Greenwich, CT annually since start of the study. The initial flood risk management solutions’ activities including data gathering, surveys, and site visits were completed by the Non-Federal sponsor as part of the in-kind work.  They also performed stream surveys, flood marks survey, existing condition hydrology and hydraulics structure inventory and valuation for the economic analysis. The team has developed the cost estimate and benefit to cost ratio for ten alternatives. The Alternative 5a - removal and replacement of the Rt. 1 Bridges plan has the maximum net benefit and is the Tentatively Selected Plan (TSP). The study is funded to completion. A Draft Integrated Feasibility Report and Environmental Impact Statement was release for public and agency review on June 28, 2018.
