Design: Civil / Site

TSPE has designed shoreline protection for many locations throughout Long Island. Design plans have included stone revetments, bluff slope flattening and gabion baskets. The stone revetment design included the evaluation of the flood elevation and wave heights anticipated for a specific year storm in order to appropriately size armor stone. The design process also included securing NYSDEC, NYSDOS and Army Corp permits in addition to local permits.

A key part of a lot of our design projects is the incorporation of new stormwater discharge systems. Typical roadway/bridge projects frequently included the design of new drainage systems in the immediate vicinity. TSPE has performed numerous analysis of watersheds with the Rational and other methods in order to ensure that new drainage systems are appropriately sized. TSPE has also performed several drainage studies for low-lying areas in order to determine cost effective techniques for the reduction of the magnitude/frequency of flooding.

TSPE has been involved in several projects where water bodies were improved in order to provide better water quality and to enhance the visual environment. Techniques used include: selective dredging to create stormwater flow paths into non-circulating areas of ponds; installation of aeration devices to increase dissolved oxygen; sediment capture devices in drainage structures, ponds and wetland vegetation to filter stormwater.

In the Site Development field, TSPE has developed site plans for multi-unit housing developments and single family residences, as well as utility modifications and site plans for facilities such as ice skating rinks and, student housing and sports facility restrooms.
