A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of roles in the environment, principally water purification, flood control, carbon sink and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life.
The SP360 is Precon’s patented, unique low impact development (LID) retention best management practices (BMP) for stormwater management.

The Franklin Park and Chesterbrook (FP&C) neighborhoods were built in the 1950s in McLean, VA. At the time, there were few if any stormwater management regulations.
