General contractor

Let It Grow, Inc.

Let It Grow performed as General Contractor for the construction of an earthen dam along the south edge of Congers Lake. This dam, which is composed of a clay liner and embankment, was the key to enable the construction of the pathway along the water’s edge. A temporary cofferdam was installed in the lake during the construction of the clay liner and rip rap embankment. This was followed by the installation of a 10″ sewer line buried 20′ deep.

An 8′ foot gabion wall was installed after the sanitary line relocation. Site clearing, excavation, PVC storm sewer, embankment and grading, pavement, traffic striping, and sign installation were also components of the project. The scope of work for the Gilchrest Road Improvement portion of the project included the construction of a 600 linear foot dike, with a 12’ wide asphalt trailway, including gabions of 12” to 15” in diameter; RCP storm sewer, “T” inlets, detention basin, 21” PVC Interceptor in conformance with Rockland County Sewer District No. 1 Standards – constructed on site. Other activities included the installation of manholes and the installation of new metal and wood fencing.
