A.
The Town of Mamaroneck hereby designates the following
areas as "critical environmental areas" (CEA) because of their exceptional
or unique character pursuant to Section 617.4 of Title 6 of the New
York Codes, Rules and Regulations:
B.
These areas were previously adopted by the Town of
Mamaroneck under Local Law No. 8 of 1986 and Local Law No. 4 of 1987.
Each of these areas is more specifically set forth in a map and descriptions
as attached.[1] The Premium River - Pine Brook Wetland Complex is described
under its former title of the Premium Salt Marsh Complex, the Hommocks
- East Creek Wetlands Complex includes descriptions of the Hommocks
Salt Marsh Complex and the East Creek Area, and the Larchmont Reservoir
- Sheldrake - Leatherstocking Freshwater Wetlands Complex is described
under the same.
[1]
Editor's Note: Documents describing these
areas are on file in the Town offices.
C.
In all places where the Sheldrake or Premium Rivers
or any stream, pond or tributary connecting thereto flow through or
are located on private property, as shown on the Town of Mamaroneck
Assessment Map, the critical environmental area is on the streambed
of said river, tributary, pond or stream and all land within 10 feet
of either side of the top of the streambanks.
A.
General description. This area, totaling some 40 acres,
consists of major parts of the Premium River, Premium Marsh and Premium
Mill Pond and associated lands and waters nearby. Together with the
smaller Pine Brook - Premium Border, an adjacent critical environmental
area in the neighboring Village of Larchmont and similar marshlands
and waters in the adjoining coastal section of New Rochelle, this
complex constitutes an important coastal fish and wildlife habitat
area, offers major aesthetic and recreational values and contributes
to the mitigation of flooding through the capacity of the marsh to
absorb stormwater. Being located at the south of the Pine Brook -
Premium watershed, which drains highly developed residential and commercial
areas, this complex requires protection against the adverse impact
of flooding, siltation and pollution.

includes all lands and adjacent waters within, and certain land directly

critical environmental area in the Village of Larchmont known as the
"Hommocks Border" and with a portion of the Hommocks Conservation
Area lying across the boundary in the Village of Mamaroneck and similarly
dedicated by that village, this complex constitutes an important coastal
fish and wildlife habitat area, offers major aesthetic and recreational
values and therefore merits special protection from adverse impact
of future action in the highly developed residential and commercial
areas immediately upstream.
B.

bodies and other geographical features referred to below are as shown
on the Tax Assessment Maps of the Town of Mamaroneck.

A.
General description of component parts and their value
to the community.
(1)
This complex consists of five areas of open space
in the unincorporated area of the Town, together with connecting water
bodies (streams, ponds and drainage ditches) and land margins immediately
adjacent to such water bodies as provided herein. All these parts
of the complex are situated in the Sheldrake River watershed. Together,
they constitute an important fish and wildlife habitat complex (see
Policy 7/7A of the Town of Mamaroneck - Village of Larchmont Local
Waterfront Revitalization Program). The open spaces in the complex
provide water-retention capacity which contributes to the lessening
of flooding and erosion in downstream parts of the watershed; they
also provide visual relief and associated recreational values in this
highly developed area. The wetlands and water bodies in the complex,
in view of their ecological, drainage and related educational and
recreational values, require special protection from flooding, siltation,
pollution and other types of adverse impact.
(2)
The total area of the complex is approximately 529
acres.
