Storm sewers — See Ch. 128.
Subdivision of land — See Ch. 175.
Zoning — See Ch. 185.
It is hereby determined that:
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;
This stormwater runoff contributes to increased quantities of waterborne pollutants, including siltation of aquatic habitat for fish and other desirable species;
Clearing and grading during construction tends to increase soil erosion and add to the loss of native vegetation necessary for terrestrial and aquatic habitat;
Improper design and construction of stormwater management practices can increase the velocity of stormwater runoff, thereby increasing streambank erosion and sedimentation;
Impervious surfaces allow less water to percolate into the soil, thereby decreasing groundwater recharge and stream baseflow;
Substantial economic losses can result from these adverse impacts on the waters of the municipality;
Stormwater runoff, soil erosion and nonpoint source pollution can be controlled and minimized through the regulation of stormwater runoff from land development activities;
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; and
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 the Town, and to address the findings of fact in § 127-1A of this chapter. This chapter seeks to meet those purposes by achieving the following objectives:
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 GP-02-02, as amended or revised;
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, as amended or revised;
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;
Minimize increases in pollution caused by stormwater runoff from land development activities which would otherwise degrade local water quality;
Minimize the total annual volume of stormwater runoff which flows from any specific site during and following development to the maximum extent practicable; and
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.

Prior to the issuance of final approval of a land development activity that has a stormwater management facility that will remain in private ownership as one of the requirements, the record owner of the stormwater management facility shall execute a maintenance and inspection easement agreement running to the benefit of the Town. The maintenance and inspection easement agreement shall provide for maintenance of the facility, by the owner, in accordance with the requirements of this chapter together with access to the facility at reasonable times for periodic inspection by the Town to ensure that the facility is maintained in proper working condition to meet design standards and any other provisions established by this chapter. The maintenance and inspection easement agreement shall be recorded in the office of the County Clerk after approval by the attorney for the Town.
Dedication permitted. The Town, at its sole discretion, may accept dedication of any existing or future stormwater management facility, provided such facility meets all the requirements of this chapter and includes adequate and perpetual access and sufficient area, by easement or otherwise, for inspection and regular maintenance.
Erosion and sediment control inspection.
The SMO may require such inspections as necessary to determine compliance with this chapter and may either approve that portion of the work completed or notify the applicant how the work fails to comply with the requirements of this chapter and the SWPPP as approved. To obtain inspections, the applicant shall notify the SMO at least 48 hours before any of the following as required by the SMO:
Start of construction;
Installation of sediment and erosion control measures;
Completion of site clearing;
Completion of rough grading;
Completion of final grading;
Close of the construction season;
Completion of final landscaping; and
Successful establishment of landscaping in public areas.
If any violations are found, the applicant and developer shall be notified in writing of the nature of the violation and the required corrective actions. No further work shall be conducted except for site stabilization until any violations are corrected and all work previously completed has received approval by the SMO.
Stormwater management practice inspections. The SMO is authorized to conduct inspections of stormwater management practices (SMPs). All applicants are required to submit as-built plans for any stormwater management practices located on site after final construction is completed. The plan must show the final design specifications for all stormwater management facilities and must be certified by a professional engineer.
Inspection of stormwater facilities after project completion. Inspection programs may be established by the SMO on any reasonable basis, including, but not limited to, the following: routine inspections; random inspections; inspections based upon complaints or other notice of possible violations; inspection of drainage basins or areas identified as higher-than-typical sources of sediment or other contaminants or pollutants; inspections of businesses or industries of a type associated with higher-than-usual discharges of contaminants or pollutants or with discharges of a type which are more likely than the typical discharge to cause violations of state or federal water or sediment quality standards or the SPDES stormwater permit; and joint inspections with other agencies inspecting under environmental or safety laws. Inspections may include, but are not limited to: reviewing maintenance and repair records; sampling discharges, surface water, groundwater, and material or water in drainage control facilities; and evaluating the condition of drainage control facilities and other stormwater management practices.
Submission of reports. The SMO may require monitoring and reporting from entities subject to this chapter as are necessary to determine compliance with this chapter.
Right of entry for inspection. When any new stormwater management facility is installed on private property or when any new connection is made between private property and the public stormwater system, the landowner shall grant to the Town the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection as required or allowed by this chapter. This right to enter may be granted by the maintenance and inspection easement and agreement provided in accordance with § 127-8C of this chapter.
Construction completion guarantee. In order to ensure the full and faithful compliance with an approved SWPPP, the SMO may require the applicant or developer to provide, prior to construction, a performance bond, cash escrow, or irrevocable letter of credit from an appropriate financial or surety institution which guarantees satisfactory completion of the project and names the Town as the beneficiary. The security shall be in an amount to be determined by the SMO based on submission of final design plans, with reference to actual construction and landscaping costs. The performance guarantee shall remain in force until the surety is released from liability by the Town, provided that such period shall not be less than one year from the date of final acceptance or such other certification that the facility(ies) have been constructed in accordance with the approved SWPPP, and that a one-year inspection has been conducted and the facilities have been found to be acceptable to the SMO.
Maintenance guarantee. Where stormwater management and erosion and sediment control facilities are to be operated and maintained by the developer or by a corporation that owns or manages a commercial or industrial facility, the developer, prior to construction, may be required to provide the Town with an irrevocable letter of credit from an approved financial institution or surety to ensure proper operation and maintenance of all stormwater management and erosion control facilities both during and after construction, and until the facilities are removed from operation. If the developer or landowner fails to properly operate and maintain stormwater management and erosion and sediment control facilities, the Town may draw upon the account to cover the costs of proper operation and maintenance, including engineering and inspection costs.
Recordkeeping. The SMO may require entities subject to this chapter to maintain records demonstrating compliance with this chapter.
Notice of violation. When the SMO determines that a land development activity is not being carried out in accordance with the requirements of this chapter, the SMO may issue a written notice of violation to the landowner, applicant and/or developer. The notice of violation shall contain:
The name and address of the landowner, developer and/or applicant;
The address, when available, or a description of the building, structure or land upon which the violation is occurring;
A statement specifying the nature of the violation;
A description of the remedial measures necessary to bring the land development activity into compliance with this chapter and a time schedule for the completion of such remedial action; and
A statement of the penalty or penalties that shall or may be assessed against the person to whom the notice of violation is directed.
Stop-work orders. The SMO may issue a stop-work order for violations of this chapter. Persons receiving a stop-work order shall be required to halt all land development activities, except those activities that address the violations leading to the stop-work order. The stop-work order shall be in effect until the SMO confirms that the land development activity is in compliance and the violation has been satisfactorily addressed. Failure to address a stop-work order in a timely manner may result in civil, criminal, or monetary penalties in accordance with the enforcement measures authorized in this chapter.
Violations. Any land development activity that is commenced or is conducted contrary to this chapter may be restrained by injunction or otherwise abated in a manner provided by law in an action brought by the Town in State Supreme Court. Further, the SMO may issue appearance tickets for violations of this chapter.
Penalties. In addition to or as an alternative to any penalty provided in this chapter or by law, any person who violates the provisions of this chapter shall be guilty of a violation punishable by a fine not exceeding $350 or imprisonment for a period not to exceed six months, or both for conviction of a first offense; for conviction of a second offense, both of which were committed within a period of five years, punishable by a fine not less than $350 nor more than $700 or imprisonment for a period not to exceed six months, or both; and upon conviction for a third or subsequent offense, all of which were committed within a period of five years, punishable by a fine not less than $700 nor more than $1,000 or imprisonment for a period not to exceed six months, or both. However, for the purposes of conferring jurisdiction upon courts and judicial officers generally, violations of this chapter shall be deemed misdemeanors and for such purpose only all provisions of law relating to misdemeanors shall apply to such violations. Each week's continued violation shall constitute a separate additional violation.
Withholding of certificate of occupancy. If a land development activity is conducted in violation of this chapter, the SMO may prevent the occupancy of said building or land, and the Building Inspector or Code Enforcement Officer may refuse to issue a certificate of occupancy of certificate of compliance pursuant to Chapter 64 of this Code.
Restoration of lands. Any violator may be required to restore land to its undisturbed condition. In the event that restoration is not undertaken within a reasonable time after notice, the Town may take necessary corrective action, the cost of which shall become a lien upon the property until paid.
The Town may require any person undertaking land development activities regulated by this chapter to pay reasonable costs at prevailing rates for review of SWPPPs, inspections, or SMP maintenance performed by the Town or performed by a third party for the Town.
If the provisions of any article, section, subsection, paragraph, subdivision or clause of this chapter shall be judged invalid by a court of competent jurisdiction, such order of judgment shall not affect or invalidate the remainder of any article, section, subsection, paragraph, subdivision or clause of this chapter.
