PUBLIC NOTICE: Floodplain Management

TOWN OF COEYMANS
 FLOODPLAIN MANAGEMENT

To: All interested Agencies, Groups and Individuals

This is to give notice that the Town of Coeymans has conducted an evaluation as required by Executive Order 11988 and/or 11990, in accordance with HUD regulations at 24 CFR 55.20 Subpart C Procedures for Making Determinations on Floodplain Management, to determine the potential effect that its activity in the floodplain and wetland will have on the human environment for the Sewer System Improvements Project – Phase 1 under CDBG CFA #150245. 

The Town of Coeymans owns and operates its own sanitary sewer system. The sanitary sewer system discharges to the Town’s wastewater treatment plant (WWTP) located at 67 Sewer Plant Access Rd, Coeymans, NY.  During wet weather events, the Town encounters a significant increase in sanitary sewer flow which is to be attributed to a combination of inflow and infiltration (I/I). The high flow rates result in sanitary sewer overflows (SSOs) creating both an environmental and health concern for the Town.  The high flow rates also negatively affect the WWTP resulting in violations of the SPDES Permit

Phase 1 of the Town of Coeymans Sewer System Improvements Project will address deficiencies in the sanitary sewer system to reduce SSOs. The existing trunk sewer located along Main Street consists of 15-inch asbestos cement pipe. During heavy rain events this line surcharges 4-5 times a year. To address this issue, the project proposes complete removal and replacement of the approximately 1,500 LF of 15-inch sewer located on Main Street between manholes 8 and 14-1 including the existing manholes.

The Town has also been experiencing increased maintenance on the existing pumps at the Division Street and Riverview Drive pump stations. The Riverview Drive Pump Station currently receives flow from the nearby industrial park. Future tenants are anticipated within the industrial park which will increase flow to the pump station, which has limited capacity to accept the additional flow. Pump replacements and other upgrades are needed at both pump stations to meet the level of service required by the Town’s customers.

The proposed project area is inclusive of the Riverview Drive and Division Street pump stations and 1,500 LF of 15-inch sewer located on Main Street from manhole 14-1 to manhole 8.

To reduce SSOs, sanitary sewer system infrastructure improvement activities are proposed including:

• Repair/Rehabilitation of Division and Riverview Pump Stations
• Replacement of approximately 1,500 LF of 15-inch sewer located on Main Street between manholes 8 and 14-1, and the replacement of existing manholes.
• Development of Wastewater Treatment Plant Engineering Report and Income Survey

FEMA flood mapping for the project site shows that part of the project area is designated as Zone AE or the 100-year flood plain. The location of the Riverview Dr. and Division St. Pump Stations are within the 100-year floodplain in the Town of Coeymans, Albany County.

There are three primary purposes for this notice. First, people who may be affected by activities in floodplains and those who have an interest in the protection of the natural environment should be given an opportunity to express their concerns and provide information about these areas.  Second, an adequate public notice program can be an important public educational tool.  The dissemination of information about floodplains can facilitate and enhance Federal efforts to reduce the risks associated with the occupancy and modification of these special areas.  Third, as a matter of fairness, when the Federal government determines it will participate in actions taking place in floodplains, it must inform those who may be put at greater or continued risk.

Written comments must be received by the Town of Coeymans at the following address on or before July 29, 2025: Town of Coeymans, 18 Russell Ave., Ravena, N.Y. 12143 and (518) 756-6006, Attention: Candace McHugh, Town Clerk, during normal business hours. Comments may also be submitted via email at [email protected].
