[HISTORY: Adopted by the Board of Trustees of the Village
of Mamaroneck 3-22-2010 by L.L. No. 10-2010, effective 5-4-2010. Amendments
noted where applicable.]
Due to its location, the Village of Mamaroneck is faced with
great challenges relative to the management of stormwater and the
prevention of flooding and there is a pressing need for additional
and innovative stormwater management. It has been determined by the
New York State Department of Environmental Conservation that uncontrolled
drainage and runoff associated with land development has a significant
impact upon the health, safety and welfare of the community, specifically
that:
A.
Improperly managed stormwater can increase the incidence of flooding
and the levels of floods which occur, endangering property and human
life;
B.
Land development activities and associated increases in site impervious
cover often alter the hydrologic response of local watersheds and
increase stormwater runoff rates and volumes, flooding, stream channel
erosion, or sediment transport and deposition;
C.
This stormwater runoff contributes to increased quantities of waterborne
pollutants, including siltation of aquatic habitat for fish and other
desirable species;
D.
Clearing and grading during construction tends to increase soil erosion
and add to the loss of native vegetation necessary for terrestrial
and aquatic habitat;
E.
Improper design and construction of stormwater management practices
can increase the velocity of stormwater runoff, thereby increasing
stream bank erosion and sedimentation;
F.
Impervious surfaces allow less water to percolate into the soil,
thereby decreasing groundwater recharge and stream baseflow;
G.
Substantial economic losses can result from these adverse impacts
on the waters of the municipality;
H.
Stormwater runoff, soil erosion and non-point source pollution can
be controlled and minimized through the regulation of stormwater runoff
from land development activities;
I.
The regulation of stormwater runoff discharges from land development
activities in order to control and minimize increases in stormwater
runoff rates and volumes, soil erosion, stream channel erosion, and
nonpoint-source pollution associated with stormwater runoff is in
the public interest and will minimize threats to public health and
safety;
J.
Regulation of land development activities by means of performance
standards governing stormwater management and site design will produce
development compatible with the natural functions of a particular
site or an entire watershed and thereby mitigate the adverse effects
of erosion and sedimentation from development;
K.
The Village of Mamaroneck, as the community at the bottom of the
watershed, is faced with additional challenges relative to the management
of stormwater runoff in that the floodway and overall floodplain receives
significant contributions from the upstream communities. For this
reason, certain unique approaches to the management of stormwater,
especially within the one-hundred-year floodplain, as well as carefully
regulated management practices outside of the floodplain, need to
be implemented.
[Amended 9-22-2014 by L.L. No. 17-2014, effective 10-30-2014]
The purpose of this chapter is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing within this jurisdiction and to address the findings of fact in § 294-1 hereof. This chapter seeks to meet those purposes by achieving the following objectives:
A.
Meet the requirements of Minimum Measures 4 and 5 of the State Pollution
Discharge Elimination System (SPDES) General Permit for Stormwater
Discharges from Municipal Separate Stormwater Sewer Systems (MS4s),
Permit No. GP-0-10-002, or as amended or revised;
B.
Require all land development activities to conform to the substantive
requirements of the New York State Department of Environmental Conservation
State Pollutant Discharge Elimination System (SPDES) General Permit
for Construction Activities GP-0-10-001, or as amended or revised;
C.
Minimize increases in stormwater runoff from land development activities
in order to reduce flooding, siltation, increases in stream temperature,
and stream bank erosion and maintain the integrity of stream channels;
D.
Require calculation for stormwater detention and retention on existing
properties with proposed improvements/modifications by a licensed
engineer to upgrade the stormwater management practices on these properties,
by requiring property owners to upgrade stormwater management systems
in accordance with the requirements of this chapter and subject to
the approval of the Stormwater Management Officer (SMO), in connection
with the construction of an addition to an existing structure or other
land-disturbing activity so that stormwater management practices for
the entire site (including retention, detention, runoff and discharge
into a public storm drain) are in full compliance with this chapter;
E.
Minimize increases in pollution caused by stormwater runoff from
land development activities which would otherwise degrade local water
quality;
F.
Minimize the total annual volume of stormwater runoff which flows
from any specific site during and following development to the maximum
extent practicable;
G.
Reduce stormwater runoff rates and volumes, soil erosion and nonpoint-source
pollution from land development or land-disturbing activities, and
ensure that these management practices are properly maintained and
eliminate threats to public safety wherever possible, through stormwater
management practices;
H.
Control erosion and sedimentation from land development or land-disturbing
activities so as to prevent it from being deposited in streams, brooks,
rivers, watercourses and other receiving water bodies;
I.
Facilitate the removal of pollutants in stormwater runoff so as to
perpetuate the natural biological and recreational functions of streams,
rivers, water bodies and wetlands;
J.
Regulate discharge of pollutants to the MS4 and promote public awareness
of the hazards of the improper discharge of pollutants into the MS4.
In accordance with Article 10 of the Municipal Home Rule Law
of the State of New York, the Board of Trustees of the Village of
Mamaroneck has the authority to enact and amend local laws for the
purpose of promoting the health, safety or general welfare of the
Village of Mamaroneck and for the protection and enhancement of its
physical environment. The Board of Trustees of the Village of Mamaroneck
may include in any such local law provisions for the appointment of
any municipal officer, employees, or independent contractor to effectuate,
administer and enforce such local law.

[Added 9-22-2014 by L.L. No. 17-2014, effective 10-30-2014]
In the context of stormwater management, the term "green
infrastructure" includes a wide array of practices at multiple scales
to manage and treat stormwater, maintain and restore natural hydrology
and ecological function by infiltration, evapotranspiration, capture
and reuse of stormwater, and establishment of natural vegetative features.
On a regional scale, green infrastructure is the preservation and
restoration of natural landscape features, such as forests, floodplains
and wetlands, coupled with policies such as infill and redevelopment
that reduce overall imperviousness in a watershed or ecoregion. On
the local scale green infrastructure consists of site- and neighborhood-specific
practices and runoff reduction techniques. Such practices essentially
result in runoff reduction and/or establishment of habitat areas with
significant utilization of soils, vegetation, and engineered media
rather than traditional hardscape collection, conveyance and storage
structures. Some examples include green roofs, trees and tree boxes,
pervious pavement, rain gardens, vegetated swales, planters, reforestation,
and protection and enhancement of riparian buffers and floodplains.
