Sunrise Highway (NY-27) Oakdale Merge Planning / Feasibility Study

As part of a Regional Design Services Agreement (RDSA), the project served to identify, evaluate, and document existing conditions and deficiencies and propose feasible conceptual alternatives to mitigate said deficiencies.

The project site experienced significant congestion and delays during peak travel periods, as motorists encountered recurring bottleneck in the eastbound and westbound approaches to Oakdale Merge.

The feasibility study described the highway facility and its role in the local and regional surface transportation network, defined existing operational issues and deficiencies, established the need for a capital construction project to reduce the issues, recommended and assessed various alternatives, and assessed the impacts of each proposed alternative.

The scope of work also included review of environmental impacts due to the site’s proximity to New York State of Department of Conservation (NYSDEC) wetlands and the Connetquot River State Park. The project required continuous coordination with the New York State Parks Department, NYSDEC, Suffolk County Department of Public Works (DPW), and the Town of Islip.

KC was responsible for developing detailed cost estimates for the alternatives identified in the feasibility study and performing HCS traffic analyses.

South Street Pump Station Emergency Generator Replacement Project

The Village of Suffern owns and operates a pump station, located on South Street, as part of the sanitary sewer collection system. This pump station is the largest within the collection system and serves as the primary pump station. The pump station is located within the floodway of the floodplain, and received significant damage during Hurricane Irene, which also had a direct impact on the emergency generator.

KC was responsible for providing engineering consulting services for the project, which included performing site and existing condition investigations and preparing design documents, specifications, and the engineering cost estimate. KC also provided bid phase services, including preparation of bid and contract documents.

The scope of construction work included removal of the existing generator, all associated accessories, and the transfer switch; installation of a 150-kilowatt (kW) generator and automatic transfer switch; reconnection of the new generator to the existing control panels; and installation of all wiring, conduit, and appurtenances to and from the new generator to provide a complete and functional backup power generation system.

Adirondack Welcome Center

As part of a Regional Design Services Agreement (RDSA), this project served to construct a new I-87 northbound welcome center in West Glens Falls. The new facility replaced an existing rest area in excess of 25 years old. The new Adirondack Welcome Center included construction of a new building with parking lot and boat inspection areas, lighting, a new septic system, waterline work, and utility upgrades.

As subconsultant, KC was responsible for assisting New York State Department of Transportation (NYSDOT) with reviewing and reapplying for New York State Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination System (SPDES), water connection system, and septic system permitting.

KC also provided detailed design for water supply, wastewater septic, and stormwater systems; design survey and mapping for confirmation of existing infrastructure; preliminary building and site construction cost estimating; and existing utilities identification and coordination. KC also developed site drainage, sanitary system, and grading design alternatives; identified existing drainage basins to determine the impact of proposed construction on erosion and sedimentation; developed the Stormwater Pollution Prevention Plan (SWPPP); and prepared cross sections to outline existing ground and proposed roadway surfaces.
