The Common Council of the City of Ithaca hereby makes the following findings:
A. 
Land development activities and increases in site impervious cover permanently alter the hydrologic responses of local watersheds and increase stormwater runoff rates and volumes, which in turn increase flooding, stream channel erosion and sediment transport and deposition, and decrease the recharge of groundwater resources;
B. 
Stormwater runoff from developed areas contributes significant quantities of water-borne particulates and pollutants to surface and groundwater sources, degrading the water quality of water bodies, affecting public and private water supplies and recreational uses, and threatening fish and other aquatic life;
C. 
The clearing and loss of vegetation, and the grading of the soil for development or redevelopment purposes may increase soil erosion, leading to siltation of water bodies, decreasing their capacity to hold and transport water, and degrading terrestrial and aquatic habitats;
D. 
The southern end of Cayuga Lake has been placed on the New York State Section 303(d) List of Impaired Waters, with both phosphorus and silt/sediment being major source contributors of the impairment;
E. 
Improper design, construction, and implementation of stormwater and erosion control facilities may also increase stormwater runoff rates and volumes, leading to increased flooding, stream channel erosion, sediment transport and deposition and overall degradation to water bodies;
F. 
Substantial economic losses may result from these adverse impacts on the public stormwater sewer conveyance systems;
G. 
Substantial economic losses may result from these adverse impacts on community waters;
H. 
Stormwater runoff, soil erosion, and non-point source pollution can be controlled and minimized through the regulation of stormwater runoff quantity and quality from new land development and redevelopment activities, by use of both structural and nonstructural practices;
I. 
In order to serve the public interest and minimize threats to the environment and to public health and safety, it is imperative to regulate stormwater runoff from land development activities and other construction activities within the City of Ithaca so as to control and minimize increases in stormwater runoff rates and volumes, to provide for the recharge of groundwater resources, and to control and minimize soil erosion, stream channel erosion, non-point source pollution, and other threats to general water quality associated with land development activities;
J. 
City regulation of land development activities, by the establishment of performance standards governing stormwater management and site design, will act to mitigate the adverse effects associated with stormwater runoff and erosion and sedimentation caused by development.
The purpose of these Stormwater Regulations, hereinafter also referred to as the "regulations," is to establish minimum stormwater management requirements and controls to protect, maintain, and enhance the health, safety and general welfare of the citizens of the City and its natural environment.
The objectives of these Stormwater Regulations are to:
A. 
Meet the requirements of minimum measures numbered 4 and 5, contained in the New York State Department of Environmental Conservation State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Municipal Separate Stormwater Sewer Systems (MS4s) No. GP-02-02, or as such requirements have been amended or revised;
B. 
Require land development activities to conform to the substantive requirements of the SPDES General Permit for Construction Activities GP-02-01, or as such requirements have been amended or revised;
C. 
Control and reduce stormwater runoff rates and volumes, in order to reduce erosive velocities, stream bank erosion and property damage, and to maintain the integrity of stream channels and aquatic habitats;
D. 
Reduce the detrimental impacts of stormwater flows on adjacent properties and downstream communities;
E. 
Control and minimize soil erosion from land development activities and prevent the transport of sediment either through direct discharge or conveyed by public stormwater sewer systems to water bodies;
F. 
Facilitate the removal of pollutants in stormwater runoff so as not to degrade ground and surface water quality;
G. 
Protect the biological, ecological, and other beneficial functions of water bodies, such as streams, wetlands, lakes and reservoirs, from the adverse impacts of stormwater runoff;
H. 
Encourage groundwater recharge so as to maintain stream base flows, aquatic life, and adequate water supplies;
I. 
Establish provisions for the long-term responsibility for and maintenance of both structural and nonstructural stormwater control facilities and management practices to ensure that they continue to function as designed, are adequately maintained, and pose no threat to public safety;
J. 
Establish provisions to ensure that there is an adequate funding mechanism, including financial security or surety, for the proper review, inspection and long-term maintenance of stormwater facilities implemented as part of these Stormwater Regulations;
K. 
Establish administrative procedures for the submission, review, approval or disapproval of stormwater management plans, for the inspection of approved active development projects, and for long-term follow-up;
L. 
Establish provisions for enforcement and penalties for noncompliance with these Stormwater Regulations.

SPECIAL CONDITIONS
Conditions in an MS4 permit where any of the following apply:
A. 
Discharge compliance with water quality standards: the condition that applies where a municipality has been notified that the discharge of stormwater authorized under its MS4 permit may have caused or has the reasonable potential to cause or contribute to the violation of an applicable water quality standard. Under this condition, the municipality must take all necessary actions to ensure future discharges do not cause or contribute to a violation of water quality standards.

C. 
Total maximum daily load (TMDL) strategy: the condition in the municipality's MS4 permit where a TMDL, including requirements for control of stormwater discharges, has been approved by the EPA for a water body or watershed into which the MS4 discharges. If the discharge from the MS4 did not meet the TMDL stormwater allocations prior to September 10, 2003, the municipality was required to modify its stormwater management and regulation plan to ensure that reduction of the pollutant of concern specified in the TMDL is achieved.
D. 
Future TMDL approval: When a TMDL is approved in the future by the EPA for any water body or watershed into which an MS4 discharges, the municipality must review the applicable TMDL to see if it includes requirements for control of stormwater discharges. If an MS4 is not meeting the TMDL stormwater allocations, the municipality must, within six months of the TMDL's approval, modify its stormwater management program to ensure that reduction of the pollutant of concern specified in the TMDL is achieved.
