This chapter 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 Southampton in 2003, obtained State Pollutant Discharge
Elimination System (SPDES) Permit No. NYR20A454 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 Board
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 Southampton:
A. Land development, redevelopment, the building of roads and highways,
other site improvement and construction activities may alter the hydrologic
response of local watersheds and increase stormwater runoff rates
and volumes and associated increases in site impervious cover, thereby
resulting in flooding and sediment transport and deposition into local
water bodies;
B. Stormwater runoff from developed areas may contribute significant
quantities of waterborne pollutants to surface and groundwater sources,
degrading water bodies, potentially affecting public and private water
supplies, recreational uses, and impacting the viability of fish and
other aquatic life;
C. Clearing and grading during construction tends to increase soil erosion,
adding to loss of native vegetation necessary for terrestrial and
aquatic habitat;
D. Flooding conditions caused by the washing and deposition of eroded
soil on adjacent properties and roadways can result in the pollution
of bays, streams, lakes and ponds;
E. The washing, blowing, and deposition of eroded soil across and upon
roadways can decrease visibility and reduce traction of vehicles;
F. Sedimentation from erosion can clog culverts, fill drainage retention
areas, pollute and silt bays, lakes, and ponds, thereby increasing
the likelihood of flooding;
G. Improper design, construction and implementation of stormwater and
erosion control measures can lead to increased flooding, sediment
transport and deposition, as well as overall degradation of water
bodies;
H. Impervious surfaces allow less water to percolate into the subsurface
soil, thereby decreasing groundwater recharge and stream base flow;
I. Impacts from stormwater runoff, soil erosion and nonpoint-source
pollution can be minimized through the control 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, and nonpoint-source pollution
associated with stormwater runoff is in the public interest and will
minimize threats to public health and safety;
K. The implementation of performance standards governing stormwater
management and site design will result in development that is more
compatible with the natural functions of a particular site or a larger
watershed and tend to mitigate the adverse impacts due to erosion
and sedimentation caused by development;
L. Economic consequences may result from adverse impacts on the waters
of the Town.
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 residents of the Town of Southampton and to address the findings of fact and statutory authority in §
285-2. This chapter 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-0-10-002, 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. Control, restrict or prohibit activities which alter natural drainage
systems, floodplains, and other natural protective features, including
wetlands, which contribute to the accommodation of floodwaters and
retention of sediment.
D. Control, restrict or prohibit land use activities which increase
nonpoint-source pollution due to stormwater runoff which result in
discharge onto public lands, neighboring properties or natural protective
features which would degrade local water quality.
E. Assure that land and water uses in the Town are designed and conducted
using best-management practices to control flooding, stormwater runoff
and discharge onto public lands, neighboring properties, or natural
protective features.
F. Promote the recharge of stormwater into the fresh water aquifer to
protect the drinking water supply and minimize salt water intrusion.
G. Minimize the total annual volume of stormwater runoff which flows
from any specific site during and following development and redevelopment
to the maximum extent practicable.
H. Protect the biological, ecological, and other beneficial functions
of water bodies from the adverse impacts of stormwater runoff.
I. Establish provisions for the long-term responsibility for and maintenance
of stormwater control facilities and practices to ensure that they
continue to function as designed, are maintained, and pose no threat
to public safety.
J. Establish provisions to ensure that there are adequate funding mechanisms,
including financial security or surety, for the proper review, inspection
and long-term maintenance of stormwater facilities and practices implemented
pursuant to this chapter.
K. 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.
L. Establish administrative procedures for the submission, review, and
approval of stormwater management plans and for the inspection of
approved active development projects, and long-term oversight of the
stormwater control facilities and practices.
M. Promote public awareness of the hazards involved in the improper
discharge of trash, yard waste, lawn chemicals, pet waste, wastewater,
grease, oil, petroleum products, hazardous waste, sediment and other
pollutants into local watersheds and water bodies.

may be made and necessary further action may be taken in conformity
with the requirements of this chapter.
All land development or redevelopment activities shall be subject
to the following performance and design criteria:
A. Technical standards. For the purpose of this chapter, the following
documents shall serve as the official guides and specification for
stormwater management. Stormwater management practices that are designed
and constructed in accordance with these technical documents shall
be presumed to meet the standards imposed by this chapter.
(1) The New York State Stormwater Management Design Manual, hereafter
referred to as the "Design Manual," in its most recent version (including
applicable updates), which serves as the official guide for the design
of stormwater management principles, methods and practices.
(2) The New York State Standards and Specifications for Erosion and Sediment
Controls, hereafter referred to as the "Erosion Control Manual," in
its most recent version (including applicable updates), also commonly
known as the "Blue Book."
