NJDOT - FEMA Category B - EPM – Surveys

NJDOT - FEMA Category B - EPM – Surveys.jpg
Project Overview: 
McLaren as part of the New Jersey Department of Transportation’s (NJDOT) Superstorm Sandy Recovery FEMA Category B - Emergency Protective Measures effort was retained to provide surveying and engineering services for the location of debris and shoaling in State channels. The NJDOT wanted to map the condition information for all State navigation channels in the Raritan Bayshore, Monmouth, Ocean, Burlington, Atlantic and Cape May shore areas in order to protect the public from injury and harm.
McLaren's Role: 
McLaren provided bathymetric surveys for approximately 100 nautical miles of state channels, utilizing single beam sonar of sufficient density to determine the depth and 3D contour of the channel bottom in an effort to locate and map debris (sunken vessels, trees, cars, telephone poles, large household items, waterfront infrastructure, etc.). McLaren developed approximately 100 reports consisting of sidescan targets of possible debris, which included information such as latitude and longitude, NJ State Plane coordinates, an image of object and approximate dimensions.

The Village of Dobbs Ferry Waterfront Park

Dobbs Ferry.JPG
Project Overview: 
The Village was not only interested in stabilizing its shoreline, but developing the waterfront areas for recreational and/or practical use. The design included shore line stabilization; the potential of a boat berthing facilities, recreational alternatives, fishing pier; and the feasibility to install floating boat docks at the Village's Hudson River Waterfront Park.
McLaren's Role: 
McLaren provided marine engineering and surveying services for this award winning project, to evaluate and design the most cost-effective means, to develop and rehabilitate the shoreline. Services included: evaluation of the exiting stone rip-rap revetment, shore line embankment, and sheet piling conditions; a hydrographic survey; evaluation of alternatives for use of waterfront property; a cost analysis; construction documents; permitting assistance; construction administrative services; bid phase support; construction consulting services; public hearing attendance; and NYSDOS project reporting services. A key element to the success of this project was resolving coastal design issues associated with significant environmental forces, as well as federal and state coastal permitting processes. McLaren worked to resolve the physical and visual impacts on the surrounding environment.

Survey & Engineering Services, Quaspeck Park Drainage Improvements

Quaspeck Park Drainage.jpg
Project Overview: 
McLaren was retained by the Town of Clarkstown to provide surveying and site civil engineering services because several streets and adjacent resident lots in Valley Cottage were experiencing problems with both surface and subsurface drainage. Project locations included Charles Boulevard, Helene Road, Quaspeck Boulevard, East Mary Lane, West Mary Lane, and Rock Drive. To correct these deficiencies, modifications and improvements to the existing storm drain system were required.
McLaren's Role: 
McLaren’s surveying services included a boundary and limited topographic survey of four (4) parcels of land for the creation of drainage easements in favor of the Town of Clarkstown. The limited topographic survey included all utilities in the above-mentioned predefined area. Trees with a diameter greater than 8” within this predefined were located and mapped. Off-site drainage structures leading from NYS RT. 9W to Rockland Lake were also e located and mapped for Civil Design purposes. McLaren’s site/civil engineering services associated with this drainage improvement project included a site investigation, environmental assessment, hydraulic analysis, drainage analysis, drainage design, public outreach and construction administration.

Land Surveying Services: Central Park Westside Playgrounds

Central Park Picture.jpg
Project Overview: 
McLaren Engineering Group (McLaren) was retained by the Central Park Conservancy to provide services of a licensed land surveyor to develop topographic surveys for seven (7) playgrounds and adjacent landscape, located on the western perimeter of the park along Central Park West.
McLaren's Role: 
McLaren provided topographic surveys to support the Central Park Conservancy’s design projects for playgrounds on the west side of Central Park. The purpose of the surveys was to locate play equipment (posts at grade and structure outlines) pavement changes, walls, ramps, curbs, fences, benches, tree locations with diameter at breast height and base elevation, as well as locate visible utilities and incorporate data on subsurface utilities provided by CPC. For uses during design and construction, McLaren provided PK nails near each project area in accordance with NAD83 and oriented to Manhattan Borough north. L1/L2 GPS was used to create control points. Mapping of the surveys were produced in accordance with the Production Standards provided by CPC. After the data was gathered from the field, McLaren performed a comprehensive process to ensure the quality of our work, this includes L1/L2 GPS data post-process using OPUS; Horizontal and Vertical Datum calculations to bring in local control; and calculation reviews and approvals performed by a Senior Land Surveyor, and Final Mapping and Drafting reviews completed by a NYS Licensed Land Surveyor.
