It is the intent of this chapter to adopt a stormwater management and
erosion and sediment control chapter that will satisfy the relevant part of
the Phase II stormwater regulations adopted by the DEC.
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 the Village and to address the findings
of fact in this chapter. 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 MS4s, Permit No. GP-02-02
or as amended or revised;
B.
Require land development activities to conform to the
substantive requirements of 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 ensure that these management practices are properly maintained
and eliminate threats to public safety.
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 waterborne 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 base flow;
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.
A.
For the purposes of this chapter, certain terms and words
are hereby defined. Words used in the present tense include the future; words
in the singular include the plural, and words in the plural include the singular;
the word "shall" is mandatory. Notwithstanding some references for definitional
purposes to the Village Code, the omission of such references in other instances
shall not be taken as an intent not to use such definitions for specific terms
that are not defined in this section and are defined in said Code when it
is deemed by the Building Inspector or any other official, board, or committee
of the Village to be appropriate to do so.

enhancement of its physical environment. The Board of Trustees may include
in any such rules, regulations and/or local laws provisions for the appointment
of any municipal officer, employees, or independent contractor to effectuate,
administer, and enforce such rules, regulations and/or local laws.
