[HISTORY: Adopted by the Board of Trustees
of the Village of Piermont 9-25-2007 by L.L. No. 12-2007. Amendments noted
where applicable.]
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 § 169-1 hereof. This local law 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 NYS 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 § 10 of the Municipal
Home Rule Law of the State of New York, the Village Board of Trustees
of Piermont has the authority to enact local laws and amend local
laws for the purpose of promoting the health, safety or general welfare
of the Village of Piermont and for the protection and enhancement
of its physical environment. The Village Board of Trustees of Piermont
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.

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 chapter:
(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");

and Sediment Control, (Empire State Chapter of the Soil and Water
Conservation Society, 2004, most current version or its successor,
hereafter referred to as the "Erosion Control Manual").
B.

C.
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.
A.
Maintenance and inspection during construction.
(1)
The applicant or developer of the land development
activity or their representative shall at all times properly operate
and maintain all facilities and systems of treatment and control (and
related appurtenances) which are installed or used by the applicant

any approval that has a stormwater management facility as one of the
requirements, the applicant or developer must execute a maintenance
easement agreement that shall be binding on all subsequent landowners
served by the stormwater management facility. The easement shall provide
for access to the facility at reasonable times for periodic inspection
by the Village of Piermont to ensure that the facility is maintained
in proper working condition to meet design standards and any other
provisions established by this chapter. The easement shall be recorded
by the grantor in the office of the County Clerk after approval by
the counsel for the Village of Piermont.
C.

of permanent stormwater management practices installed in accordance
with this chapter shall ensure they are operated and maintained to
achieve the goals of this chapter. Proper operation and maintenance
also includes, as a minimum, the following:
