Project Description
The New York City Department of Environmental Protection (DEP) Bureau of Environmental Planning and Analysis (BEPA) has reviewed the proposed project to perform emergency repairs on Allen Rd. located in Tannersville, NY as a result of damage related to Hurricane Irene. Project Background: Allen Road serves as the only vehicular and delivery truck entrance to service the Tannersville Wa. Due to the amount of runoff and stream flow experienced as a result of Hurricane Irene and a resulting debris jam at the existing stream crossing, Allen Road is in need of repair. Due to the storm a debris jam formed at the Allen Brook stream crossing, which forced Allen Brook to overtop the roadway damaging the existing pavement, washing out sections of roadway pavement and roadside swale, damaging the existing guiderails, uncovering water main and irrigation pipes, damaging an existing timber retaining wall, eroding a golf cart path and causing further damage downgrade. Approximately, 600 feet downgrade of the culvert the storm runoff eroded a section of Allen Road approximately 75-100 in length was washed out exposing and damaging an existing 8 sewer main and 8 water main. The washout was approximately 6-8 deep and removed the entire access road servicing the WWTP. This washout is approximately 1000 feet or more south of the intersection of Allen Road with NYS Route 23A. The damaged sewer and water mains have already been repaired / restored through a BWS job order contract (JOC). Scope of Work Description: The design for the permanent repair is would include the redesign of the two (2) culvert barrel crossing of Allen Brook with a single span culvert to prevent debris blockage. The design plans are to also include plans and details for the resurfacing of Allen Road, roadside ditches (stone lined), the gravel golf cart path, the timber retaining wall, the replacement of utilities, guiderails, rebuilding of Allen Road in the vicinity of the washout area, necessary slope stabilization, and the removal of fallen / leaning trees in Allen Brook.
