Senator Robach And Mayor Duffy Announce $1 Million In State Funding For Completed Hemlock Lake Dam And Spillway Rehabilitation Project
AND SPILLWAY REHABILITATION PROJECT
Project Improved Overall Safety of Dam Used to Create Reservoir for City Water Supply
State Senator Joe Robach and Rochester Mayor Bob Duffy today announced that the City of Rochester will receive $1 million in funding from the New York State Department of Environmental Conservation Dam Safety Program to support the completed Hemlock Lake Dam and Spillway rehabilitation project. The total cost of the project was $1.38 million. The Dam Safety Program funds 75 percent of eligible costs up to $1 million.
The City of Rochester owns, operates and maintains the Hemlock Lake Dam and Spillway which is located at the north end of Hemlock Lake in the Town of Livonia, Livingston County. The dam and spillway are used to create a reservoir to supply water to the City of Rochester. The dam and spillway also provide downstream flood control for the Hemlock Outlet.
“This rehabilitation project provides for the continued safety of the dam itself and the surrounding community, and also ensures clean and safe drinking water for residents in the City of Rochester,” stated Senator Joe Robach. “The City of Rochester recognized the urgent need to address necessary improvements to the dam and spillway. However, this funding will alleviate a substantial financial burden from City taxpayers.”
“Rochester’s water system has provided pure and wholesome water to our residents and businesses for 130 years. The Hemlock dam and spillway project was a vital component to continuing to ensure safe drinking water for our community,” said Mayor Robert J. Duffy. “This state funding acknowledges the worthiness of the project and will provide some welcome relief for our taxpayers.”
In April 1996, the City hired Bergman Associates to complete the planning and preliminary engineering work required to rehabilitate the Hemlock Lake Dam and Spillway. This was completed and a report issued in September 1996. In accordance with NYSDEC’s publication, Guidelines for Design of Dams, the report made recommendations for repairs including:
· Constructing an auxiliary spillway to increase capacity
· Replacing existing stop logs with a fixed crest spillway
· Adding additional fill material to the top of the earthen dam, which had settled by as much a 2.5 feet
· Making structural modifications to the existing spillway and repair of deteriorated concrete
· Extending existing wave slope protection to control against erosion
Final design of the project began in October of 1996 and was completed in April 1997. Construction began in August 1997 and was completed in 1999. The exclusive purpose of the project was to improve the overall safety of the dam and its appurtenant works, thereby minimizing the risk of failure and subsequent hazard to life and property located downstream of the dam. The project did not increase the water supply yield of Hemlock Lake.
In 1997, the City of Rochester authorized the issuance of $1.38 million in bonds to fund the project. These state funds will provide $1 million towards this total project cost.
“I am happy to join with Mayor Duffy on issues like this that affect residents in the City of Rochester. I look forward to continuing to work with the mayor to address the needs of the City and to help deliver the necessary resources to make sure Rochester remains a great place to live and work” Robach added.
