[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
and enhancement of its physical environment. The Town of Wilton 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.
D. Applicability.
(1)
This article shall be applicable to all land
development activities as defined in this chapter.
(2)
The municipality shall designate a Stormwater
Management Officer who shall accept and review all stormwater pollution
prevention plans and forward such plans to the applicable municipal
board. The Stormwater Management Officer may:
(b)
Upon approval by the Town Board of the Town
of Wilton, engage the services of a registered professional engineer
(PE), registered landscape architect (RLA), or certified professional
in erosion and sediment control (CPESC) to review the plans, specifications
and related documents at a cost not to exceed a fee schedule established
by said governing board; or
(c)
Accept the certification of a PE or RLA that
the plans conform to the requirements of this article.
(3)
All land development activities subject to review
and approval by the Town Board, or other designated Board, of the
Town of Wilton under subdivision, site plan, and/or special use permit
regulations shall be reviewed subject to the standards contained in
this article.
(4)
All land development activities not subject to review as stated in Subsection
D(3) shall be required to submit a stormwater pollution prevention plan (SWPPP) to the Stormwater Management Officer, who shall approve the SWPPP if it complies with the requirements of this article.
E. Exemptions. The following activities may be exempt
from review under this article:
(1)
Agricultural activity as defined in this chapter.
(3)
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, including
road maintenance that does not disturb the soil, such as repaving.
(4)
Repairs to any stormwater management practice
or facility deemed necessary by the Stormwater Management Officer.
(5)
Any part of a subdivision if a plat for the
subdivision has been approved by the Town of Wilton on or before the
effective date of this article, but is still subject to the regulations
set forth in SPDES General Permit.
(6)
Land development activities for which a building
permit has been approved on or before the effective date of this article.
(7)
Individual cemetery graves.
(8)
Installation of fence, sign, telephone, and
electric poles and other kinds of posts or poles.
(9)
Emergency activity immediately necessary to
protect life, property or natural resources.
(10)
Activities of an individual engaging in home
gardening by growing flowers, vegetable and other plants primarily
for use by that person and his or her family.
(11)
Landscaping and horticultural activities in
connection with an existing structure.
All land development activities shall be subject
to the following performance and design criteria:
A. Technical standards. For the purpose of this article,
the following documents shall serve as the official guides and specifications
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 article:
(1)
The New York State Stormwater Management Design
Manual (New York State Department of Environmental Conservation, most
current version or its successor, hereafter referred to as the "Design
Manual").
(2)
New York Standards and Specifications for Erosion
and Sediment Control, (Empire State Chapter of the Soil and Water
Conservation Society, August 2004, most current version or its successor,
hereafter referred to as the "Erosion Control Manual").
B. Water quality standards. Any land development activity
shall not cause an increase in turbidity that will result in substantial
visible contrast to natural conditions in surface waters of the State
of New York.
