USRB Feasibility Study Overview

Upper Susquehanna River Basin Comprehensive Flood Damage Reduction Feasibility Study

Within New York, the Upper Susquehanna River Basin (USRB), excluding the Chemung River watershed, drains approximately 4,520 square miles in the south central part of the state. The United States Army Corps of Engineers (USACE) has constructed 20 flood risk management projects in the USRB dating back to 1938

USACE and New York State Department of Environmental Conservation plan to evaluate many of these projects under USACE’s feasibility study process. This feasibility study will identify the current risk for flooding and propose ways to minimize the impact from flood events, preliminarily determine environmental and economic impact from various levels of flooding, and suggest structural and non-structural alternatives that could help minimize damage to life and property. 

The feasibility study will involve updating existing hydrologic and hydraulic models of the USRB, defining levels of protection at the existing levee/floodwall projects, and determine preliminary economic benefits for all of the existing levees/floodwalls.

One flood risk management project location will be chosen by the Project Delivery Team and formulation will begin to develop concept design alternatives involving varying levels of protection. Evaluation of these alternatives will be done using Hydrologic Engineering Center Flood Damage Assessment model and a comparison will follow to determine an alternative that yields the greatest National Economic Development benefits.

Public Meetings

Public scoping meetings were held in November 2016 for the study in three different municipalities including Owego Village on November 21, 2016, the Town of Chenango on November 22, 2016 and the Village of Sidney on November 30, 2016. Study questions from the audience and resultant discussions at each meeting were general in nature.  A paraphrased record of questions and discussion from each meeting is presented here.
