The Village of Rye Brook finds that:
A. Land development activities and associated increases
in site impervious cover often alter the hydrologic response of local
watersheds and increase: a) stormwater runoff rates and volumes; b)
flooding; c) stream channel erosion; or d) sediment transport and
deposition;
B. Stormwater runoff contributes to increased quantities
of waterborne pollutants, including siltation of aquatic habitat for
fish and other desirable species;
C. Stormwater runoff can carry pollutants into receiving
water bodies and degrade water quality;
D. Clearing and grading during construction tends to
increase soil erosion and add to the loss of native vegetation necessary
for terrestrial and aquatic habitats;
E. Improper design and construction of stormwater management
practices can increase the velocity of stormwater runoff, thereby
increasing streambank erosion and sedimentation;
F. Impervious surfaces allow less water to percolate
into the soil, thereby decreasing groundwater recharge and stream
base flow;
G. Improperly managed stormwater runoff can increase
the incidence of flooding and the level of floods that occur, endangering
property and life;
H. Substantial economic losses can result from these
adverse impacts on the waters of the municipality;
I. Stormwater runoff, soil erosion and nonpoint-source
pollution can be controlled and minimized through the regulation of
stormwater runoff from land development activities;
J. 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; and
K. Regulation of land development activities by means
of performance standards management and site design will produce development
compatible with the natural governing stormwater functions of a particular
site or an entire watershed and thereby mitigate the adverse effects
of erosion and sedimentation from development.
[Amended 3-8-2011 by L.L. No. 1-2011]
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 §
217-2 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 SPDES General Permit
for Stormwater Discharges from Municipal Separate Stormwater Sewer
Systems (MS4s), Permit No. GP-02-02, as amended or revised;
B. Require
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-02-01, 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 streambank erosion and maintain the integrity of stream channels;
D. Promote
groundwater recharge and maintain stream base flow.
E. Minimize
increases in pollution caused by stormwater runoff from land development
activities that would otherwise degrade local water quality;
F. Minimize
the total annual volume of stormwater runoff that 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 wherever possible through stormwater management practices
and to ensure that these management practices are properly maintained
and eliminate threats to public safety; and
H. Encourage
the use of green infrastructure practices to control stormwater runoff
such as protecting natural areas, reducing impervious cover, and runoff
reduction techniques to the maximum extent practicable.
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 Rye Brook has the authority to enact and amend local laws
for the purpose of promoting the health, safety or general welfare
of the Village of Rye Brook and for the protection and enhancement
of its physical environment. The Village Board of Trustees 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.
