It is hereby determined that:
A. Uncontrolled drainage and runoff associated with land development
has a significant impact upon the health, safety and welfare of the
community.
B. Eroded soil endangers water resources by reducing water quality and
causing the silting of streams, lakes and other water bodies, adversely
affecting aquatic life.
C. Stormwater runoff and sediment transports pollutants such as heavy
metals, hydrocarbons, nutrients and bacteria to water resources, degrading
water quality.
D. Eroded soil necessitates repair and accelerates the maintenance needs
of stormwater management facilities.
E. Clearing, grading and altering natural topography during construction
tends to increase erosion.
F. Improper design and construction of drainage facilities can increase
the velocity of runoff, thereby increasing stream bank erosion and
sedimentation.
G. Impervious surfaces increase the volume and rate of stormwater runoff
and allow less water to percolate into the soil, thereby decreasing
groundwater recharge and stream base flow.
H. Improperly managed stormwater runoff can increase the incidence of
flooding and the severity of floods that occur, endangering property
and human life.
I. Substantial economic losses can result from these adverse impacts.
J. Stormwater runoff, soil erosion and nonpoint source pollution can
be controlled and minimized through the regulation of land development
activities.
The purpose of this chapter is to safeguard persons, protect
property, and prevent damage to the environment in the City of Troy,
New York. This chapter will also promote the public welfare by guiding,
regulating and controlling the design, construction, use and maintenance
of any land development activity as it relates to erosion and sedimentation
control and stormwater management. This chapter seeks to meet these
purposes by achieving the following objectives:
A. Meet the requirements of minimum control measures Four (construction
site stormwater runoff control) and Five (post-construction stormwater
management) of the State Pollution Discharge Elimination System (SPDES)
General Permit for Stormwater Discharges from Municipal Separate Stormwater
Sewer Systems (MS4s), Permit 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
(SPDES) General Permit for Construction Activities GP-02-01, or as
amended or revised.
C. Minimize soil erosion and sedimentation impacts on streams, water
bodies and neighboring properties.
D. Avoid excessive and/or unnecessary tree and vegetation removal.
E. Minimize windblown soil associated with properties being cleared
and graded for development.
F. Maintain the integrity of watercourses and sustain their hydrologic
functions.
G. Minimize increases in the magnitude and frequency of stormwater runoff
to prevent an increase in flood flows and the hazards and costs associated
with flooding.
H. Minimize decreases in groundwater recharge and stream base flow to
maintain aquatic life, assimilative capacity and water supplies.
I. Facilitate the removal of pollutants in stormwater runoff to perpetuate
the natural biological function of water bodies.
In accordance with § 10 of the Municipal Home Rule
Law of the State of New York, the Governing Board of the City of Troy
has the authority to enact local laws and amend local laws for the
purpose of promoting the health, safety or general welfare of the
City of Troy and for the protection and enhancement of its physical
environment. The City Council 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.
