Developing A Watershed Management Strategy

The
Bronx River watershed, like all of Westchester, was once covered by
forests, meadows, marshes and swamps, through which ran small
streams and larger rivers. Ponds dotted the landscape,
offering a rich and varied ecosystem. Today, however, the
watershed is considerably developed, especially in southern
Westchester. Low-, moderate-, and high-density housing,
shopping centers, offices, industry, and other similar land uses
have replaced much of the visible natural resources that once
dominated the landscape. Even recreational uses, like golf
courses and athletic fields, have altered the former landscape.

Unlike the forests and wetlands they replaced, parking lots, office
buildings,
shopping centers, factories, etc. do not absorb the rainfall and
melting snow that runs over and through
them, purifying the water as it goes. Instead, they shed the water,
adding pollutants like oils and
grease, metals and salts and nutrients like nitrogen and
phosphorus. This polluted stormwater
runoff
then washes into catch basins and other stormwater infrastructure,
where
it may go untreated directly into the river and its tributaries.
This adds to the degradation of water quality, thereby impeding
the river’s ability to host fish and wildlife and recreational
pursuits, like fishing and swimming.
The
Bronx River Watershed Coalition, formerly known as Watershed
Advisory Committee 7, was formed in 2003 as a partnership among
Westchester County municipalities and agencies and not-for-profit
organizations seeking the same goal: to improve water quality in the
Bronx River. Over time, state and New York City agencies joined the
effort, too. The Coalition sought to achieve its goal by developing
a comprehensive management plan, available on this website, which
lays out a strategy for limiting the amount of pollution entering
the river and its tributaries via stormwater runoff.
Coalition members included municipalities in Westchester County
whose boundaries fall wholly or partly within the Bronx River
watershed: Ardsley, Bronxville, Eastchester, Elmsford, Greenburgh,
Harrison, Mount Pleasant, Mount Vernon, New Castle, North Castle,
Scarsdale, Tuckahoe, White Plains, and Yonkers. Other members
include the Westchester County
Department of Planning, Westchester County Department of Parks,
Recreation and Conservation, and the Bronx River Conservancy, Bronx
River Alliance, Kensico Environmental Enhancement Program, New York
City Department of Parks and Recreation, New York City Department of
Environmental Protection, New York Department of State Division of
Coastal Resources, and New York Department of Environmental
Conservation Division of Water.
The
Center for Watershed Protection, Biohabitats, and Northern
Ecological Associates assisted staff of the Westchester County
Department of Planning in developing the Bronx River Watershed
Management Plan. The U.S. Army Corps of Engineers, New York
District, and Westchester County Department of Health and Department
of Laboratories and Research also provided assistance.
