It is hereby determined that:
A. Land development activities and associated increase
in site impervious cover often alter the hydrologic response of local
watersheds and increase stormwater runoff and volumes, flooding, stream
channel erosion, or sediment transport and deposition;
B. This stormwater runoff contributes to increased quantities of waterborne
pollutants, including siltation of aquatic habitat for fish and other
desirable species;
C. Cleaning and grading during construction tends to increase soil erosion
and add to the loss of native vegetation necessary for terrestrial
and aquatic habitats;
D. Improper design and construction of stormwater management practices
can increase the velocity of stormwater runoff, thereby increasing
stream bank erosion and sedimentation;
E. Impervious surfaces allow less water to percolate into the soil,
thereby decreasing groundwater recharge and stream baseflow;
F. Substantial economic losses can result from these adverse impacts
on the waters of the Village;
G. Stormwater runoff, soil erosion and nonpoint source pollution can
be controlled and minimized through the regulation of stormwater runoff
and land development activities;
H. The regulation of stormwater runoff discharges from land development
activities in order to control and minimize increase 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;
I. Regulation of land development activities by means of performance
standards governing stormwater management and site design will produce
development compatible with natural functions of a particular site
or an entire watershed and thereby mitigate the adverse effects of
erosion and sedimentation from development.
The purpose of this chapter and Ch.
252, Art.
XVII, 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 §
209-1 hereof. This chapter and Ch.
252, Art.
XVII, 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 System (MS4s), Permit No. GP-02-02, as amended or revised;
B. Require land development activities to conform to the substantive
requirements of the NYS Department of Environmental Conservation State
Pollutant Discharge Elimination System (SPDES) General Permit for
Construction Activities, GP-02-01, 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. Minimize increases in pollution caused by stormwater runoff from
land development activities which would otherwise degrade local water
quality;
E. Minimize the total annual volume of stormwater runoff which flows
from any specific site during and following development to the maximum
extent practicable; and
F. 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.
In accordance with § 10 of the Municipal Home Rule
Law of the State of New York, the Village Board has the authority
to enact local laws and amend local laws for the purpose of promoting
the health, safety and/or general welfare of the Village of Lynbrook
and for the protection and enhancement of its physical environment.
The Village Board may include in any such local law provisions for
the appointment of any Village officer, employees, or independent
contractor to effectuate, administer and enforce such local law.
The following activities may be exempt from review under this chapter and Ch.
252, Art.
XVII:
A. Agricultural activity as defined in §
252-204.
B. Silvicultural activity, except that landing areas and log haul roads are subject to this chapter and Ch.
252, Art.
XVII.
C. Routine maintenance activities that disturb less than five acres
and are performed to maintain the original line and grade, hydraulic
capacity or original purpose of a facility.
D. Repairs to any stormwater management practice or facility deemed
necessary by the Stormwater Management Officer.
E. Any part of a subdivision if a plat for the subdivision has been approved by the Planning Board on or before the effective date of this chapter and Ch.
252, Art.
XVII.
F. Land development activities for which a building permit has been approved on or before the effective date of this chapter and Ch.
252, Art.
XVII.
H. Installation of fence, sign, telephone, and electric poles and other
kinds of posts or poles.
I. Emergency activity immediately necessary to protect life, property
or natural resources.
J. Activities of an individual engaging in home gardening by growing
flowers, vegetables and other plants primarily for use by that person
and his or her family.
K. Landscaping and horticultural activities in connection with an existing
structure.
