[Adopted 7-29-2011 by L.L. No. 5-2011]
This article is enacted pursuant to § 10 of the Municipal
Home Rule Law to promote the public health, safety, and general welfare
of Town citizens through land use regulations intended to control
flooding, erosion, or sedimentation within the entire Town, as mandated
by Articles 17 (Title 7.8), 36 and 70 of the Environmental Conservation
Law and any and all applicable laws, rules or regulations of the State
of New York.
The Town of Shelter Island in 2009 was given State Pollutant
Discharge Elimination System (SPDES) permit number GP-0-08-002 from
the New York State Department of Environmental Conservation (NYSDEC)
in connection with the discharge of stormwater, as required pursuant
to the Environmental Conservation Law (ECL). The SPDES permit requires
that the Town enact a local law that complies with federal and New
York State guidelines for stormwater control, which addresses the
following findings of fact as determined by the State and as accepted
by the Town of Shelter Island:
A. 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.
B. This stormwater runoff contributes to increased quantities of water-borne
pollutants, including siltation of aquatic habitat for fish and other
desirable species.
C. Clearing and grading during construction tends to increase soil erosion,
adding to loss of native vegetation necessary for terrestrial and
aquatic habitat.
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 municipality.
G. Stormwater runoff, soil erosion and nonpoint source pollution can
be controlled and minimized through the regulation of stormwater runoff
from land development activities.
H. 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.
I. 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.
The purpose of this article is to establish minimum stormwater management requirements and controls to protect and safeguard the general health, safety, and welfare of the residents of the Town of Shelter Island and to address the findings of fact and statutory authority in §
110-31. This article seeks to meet those purposes by achieving the following objectives:
A. Meet the requirements of minimum Measures 4 and 5 of the New York
SPDES General Permit for Stormwater Discharges from Municipal Separate
Storm Sewer Systems (MS4s), Permit No. GP-0-08-002, or as amended
or revised.
B. Require land development activities to conform to the substantive
requirements of the New York SPDES General Permit for Stormwater Discharges
from Construction Activity, Permit No. 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 streambank 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.
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.
G. Establish provisions for the Town to recover costs and expenses incurred
by the Town for any repairs it makes to stormwater facilities and
for implementation of management practices.
