Term Agreement for Stormwater Management

NYS Department of Transportation, Regions 8, 10 & 11

Under this “On-Call Agreement” LKMA has been involved with multiple assignments, including:

Inventories Illicit Stormwater Discharge
Drainage Studies

Completed an update of existing inventories of over 3,500 drainage outfalls on State highways in Orange, Ulster, Putnam and Dutchess Counties, as well as four of the five boroughs of New York City. The work was completed under tight timeframes to enable submissions to be made to USEPA. Data, including GPS-based locations and field photos, was collected by multiple teams of technicians using iPads equipped with ArcGIS Collector and was continuously uploaded to a cloud-based platform for monitoring in the office and the production of progress reports. In addition to the inventory update, field personnel identified suspected illicit discharges emanating from the outfalls.

Flushing Meadows-Corona Park Drainage Study:

In the development of stormwater Best Management Practice measures to alleviate flooding on the Van Wyck Expressway, LKMA developed a hydraulic and hydrologic model of the 1,000-acre urban watershed. High groundwater levels and tidal influence in the adjacent Flushing Bay contribute to the flooding. Analysis and simulation of design-year storm stormwater flow was performed using the USEPA SWMM program.

Noise and Lead Mitigation at Suffolk County Trap & Skeet Range, Southaven County Park

Suffolk County Department of Public Works

Project entailed an evaluation of sound reduction structures and/or methodologies to mitigate noise impacts on the adjacent communities from Trap, Skeet and Sporting Clay venues at a 60-acre County shotgun range. A previous noise study and proposed mitigation measures were reviewed and evaluated. Additional noise mitigation techniques were evaluated, and various noise barrier materials were investigated along with estimated construction costs. In addition, the remediation of lead shot was investigated and discussed along with a recommended course of action. Complete topographic field survey with digital mapping and DTM were provided along with a report summarizing our findings.

Town of Southold Fueling Station

Town of Southold Engineering Department

In 2014, L.K. McLean Associates was hired by the Town’s permitted, design, constructed and now being used by the Town of Southold is a project known As the Southold Town Fueling Facility situated at the Southold Town Highway Yard in Peconic. The project was an important part of addressing many Health Department violations involving unregistered above ground storage tanks used for fueling and heating purposes at his site. Two (2) 8,000 gallon above ground tanks provide diesel and gasoline product to four (4) state of the art fueling dispensers covered by a steel canopy and fire suppression system. The fueling system is the Town’s primary fueling system and is now backed up by a natural gas generator if a natural disaster were to strike the east end. The project included over-fill protection, leak detection, high/low alarm system and remote access to the fuel management system. The new facility will now enable the Town to decommission the unregistered tanks in order to address the violations with the County.
