[Added 12-7-2006 by L.L. No. 4-2006]
[Amended 8-1-2019]
In addition to this article, all development
activities must comply with other applicable state and federal laws,
including NYS SPDES General Permit.
A.
Findings of fact. It is hereby determined that:
(1)
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;
(2)
This stormwater runoff contributes to increased
quantities of water-borne pollutants, including siltation of aquatic
habitat for fish and other desirable species;
(3)
Clearing and grading during construction tend
to increase soil erosion and add to the loss of native vegetation
necessary for terrestrial and aquatic habitat;
(4)
Improper design and construction of stormwater
management practices can increase the velocity of stormwater runoff,
thereby increasing stream bank erosion and sedimentation;
(5)
Impervious surfaces allow less water to percolate
into the soil, thereby decreasing groundwater recharge and stream
base flow;
(6)
Substantial economic losses can result from
these adverse impacts on the waters of the municipality;
(7)
Stormwater runoff, soil erosion and nonpoint
source pollution can be controlled and minimized through the regulation
of stormwater runoff from land development activities;
(8)
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.
(9)
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.
B.
Purpose. 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 public
residing within this jurisdiction and to address the findings of fact
in this section. This article seeks to meet those purposes by achieving
the following objectives:
(1)
Meet the requirements of minimum measures 4
and 5 of the New York State Department of Environmental Conservation
(NYSDEC) State Pollution Discharge Elimination System (SPDES) General
Permit for Stormwater Discharges from Municipal Separate Stormwater
Sewer Systems (MS4s) Permit, or as amended or revised;
(2)
Require land development activities to conform
to the substantive requirements of the NYS SPDES General Permit for
Construction Activities General Permit, or as amended or revised;
(3)
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;
(4)
Minimize increases in pollution caused by stormwater
runoff from land development activities which would otherwise degrade
local water quality;
(5)
Minimize the total annual volume of stormwater
runoff which flows from any specific site during and following development
to the maximum extent practicable; and
(6)
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.
C.
Statutory authority. In accordance with § 10
of the Municipal Home Rule Law of the State of New York, the Town
Board of the Town of Wilton has the authority to enact local laws
and amend local laws and for the purpose of promoting the health,
safety or general welfare of the Town of Wilton and for the protection
