It is hereby determined that:
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
and add to the 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 chapter 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 § 222-1 hereof. This chapter 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 Systems (MS4s), Permit No. GP-02-02 or as amended or revised;
B.
Require land development activities to conform to the substantive
requirements of the New York State Department of Environmental Conservation
State Pollutant Discharge Elimination System (SPDES) General Permit
for Construction Activities GP-02-01 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; 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 Article 10 of the Municipal Home Rule Law
of the State of New York, the Village Board of Trustees of Spring
Valley 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 Village of Spring Valley and for the protection and enhancement
of its physical environment. The Village Board of Trustees of Spring
Valley 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.
B.
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:
(1)
Review the plans;
(2)
Upon approval by the Village Board of Trustees of the Village of
Spring Valley, engage the services of a registered professional engineer
to review the plans, specifications and related documents at a cost
not to exceed a fee schedule established by said governing board;
or
(3)
Accept the certification of a licensed professional that the plans
conform to the requirements of this chapter.
C.
All land development activities subject to review and approval by
the applicable board of the Village of Spring Valley under subdivision,
site plan, and/or special permit regulations shall be reviewed subject
to the standards contained in this chapter.
The following activities may be exempt from review under this
chapter:
A.
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.
B.
Repairs to any stormwater management practice or facility deemed
necessary by the Stormwater Management Officer.
C.
Any part of a subdivision if a plat for the subdivision has been
approved by the Village of Spring Valley on or before the effective
date of this chapter.
D.
Land development activities for which a building permit has been
approved on or before the effective date of this chapter.
E.
Cemetery graves.
F.
Installation of fence, sign, telephone, and electric poles and other
kinds of posts or poles.
G.
Emergency activity immediately necessary to protect life, property
or natural resources.
H.
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.
I.
Landscaping and horticultural activities in connection with an existing
structure.
