Gowanus Canal Watershed/Waterbody Facility Plan
The Gowanus Canal Watershed/Waterbody Facility Plan is the first phase of developing a Long Term Control Plan for this waterbody. This Plan assesses the ability of the existing New York City CSO Facility Plan for the Gowanus Canal to provide compliance with existing water quality standards. Implementation of the Plan is expected to reduce CSO discharges to the Gowanus Canal, which will eliminate odors, greatly reduce floatables, and improve dissolved oxygen concentrations to meet the existing water quality standards.

Jamaica Bay Watershed Protection Plan
On July 20, 2005, Mayor Bloomberg signed a City Council bill requiring the DEP to create a watershed protection plan for the watershed/sewershed of Jamaica Bay. The legislation established a pathway towards restoring and maintaining the water quality and ecological integrity of the Bay by evaluating threats to the Bay and coordinating environmental remediation and protection efforts in a focused and cost-effective manner. In addition, DEP was required to create a plan advisory committee to provide advice and recommendations the final watershed protection plan.

The Staten Island Bluebelt: A Natural Solution to Storm Water Management
The Staten Island Bluebelt provides ecologically-sound and cost-effective storm water management for the South Richmond area of Staten Island. The project preserves streams, ponds and other wetland areas – called Bluebelts – allowing them to perform their natural functions of conveying, storing, and filtering storm water. In addition, the Bluebelts also provide important community open spaces and diverse wildlife habitats.

Gilboa Dam Stabilization Project Completed
Commissioner Emily Lloyd was in Gilboa on December 14 to mark the end of the Gilboa Dam stabilization project. In the span of one year, the DEP completed a $24 million project to make the dam safe by installing 80 anchoring cables that pin the dam down to the bedrock below. A $300 million full-scale reconstruction of the dam will begin in 2008. That project will add up to 12 feet of mass to the dam, reconstruct the spillway and dam face, install a new diversion tunnel around the dam from the Schoharie Reservoir into Schoharie Creek, and construct a floodgate at the top of the dam that will allow for quick releases of water in order to help control flooding downstream.

Brooklyn-Queens Aquifer Feasibility Study

Brooklyn-Queens Aquifer Feasibility Study
DEP is conducting the Brooklyn-Queens Aquifer Feasibility Study to investigate the viability of using groundwater from Jamaica aquifers to supplement the drinking water and simultaneously reducing flooding in Southeastern Queens. The study also involves groundwater cleanup of the West Side Corporation, a New York State Department of Environmental Conservation Class 2 hazardous waste disposal site.
