This chapter shall be known as the "Stormwater Management and Erosion
Control Ordinance."
The City of Canandaigua finds that uncontrolled drainage and runoff
associated with land development has a significant impact upon the health,
safety and welfare of the community. Specifically:
A. The City's stormwater drainage system is currently
stressed during heavy rain events, causing flooding in multiple locations.
B. 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.
C. This stormwater runoff contributes to increased quantities
of water-borne pollutants, including nutrients, pathogens and siltation of
aquatic habitat for fish and other desirable species.
D. Clearing and grading during construction tends to increase
soil erosion and add to the loss of native vegetation necessary for terrestrial
and aquatic habitat.
E. Improper design and construction of stormwater management
practices can increase the velocity of stormwater runoff, thereby increasing
streambank erosion and sedimentation.
F. Impervious surfaces allow less water to percolate into
the soil, thereby decreasing groundwater recharge and stream base flow.
G. Substantial economic losses can result from these adverse
impacts on the waters of the municipality.
H. Stormwater runoff, soil erosion phosphorus loading and
other nonpoint source pollutants can be controlled and minimized through the
regulation of stormwater runoff from land development activities.
I. 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, phosphorus
loading and other nonpoint source pollutants associated with stormwater runoff
is in the public interest and will minimize threats to public health and safety.
J. 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.
It is the purpose of this chapter to protect, maintain and enhance both
the immediate and the long-term health, safety and general welfare of the
citizens of the City of Canandaigua, by regulating site preparation and construction
activities, including excavation, filling, grading, stripping, and paving,
in order to prevent problems related to erosion, flooding, sedimentation,
or drainage. In relation to this purpose, this chapter has 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 and additional
requirements in this chapter and the Enhanced Phosphorus Removal Supplement
(Chapter 10, New York State Stormwater Management Design Manual);
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 (especially phosphorus)
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 predevelopment
conditions; and
F. Reduce stormwater runoff rates and volumes, soil erosion
and phosphorus and other nonpoint source pollutants, wherever possible, through
stormwater management practices, and ensure that these management practices
are properly maintained and eliminate threats to public safety.
In accordance with Article 2-A of the General City Law of the State
of New York, the City of Canandaigua has the authority to enact ordinances
for the purpose of promoting the health, safety or general welfare of the
City of Canandaigua, including the protection of the property of its inhabitants.
By the same authority, the City of Canandaigua may include in any such ordinance
provision for the appointment of any municipal officer or employees to effectuate
and administer such ordinance.
