Article 1 - General Provisions
Article 2 – Stormwater Control
Article 3 - Administration and Enforcement
Appendix A - Stormwater Management Practices Acceptable for Water Quality
Be it enacted by the Board of Trustees of the Village of Shoreham as follows:
Article 1 General Provisions
Section 1.1 Findings of Fact
It is hereby determined that:
1.1.1 Land use activities including land development, as well as impervious surfaces such as parking lots and roads, can increase stormwater runoff rates and volumes, erosion, and sediment transport and deposition;
1.1.2 This stormwater runoff contributes to increased quantities of water-borne pollutants;
1.1.3 Clearing and grading during construction tends to increase soil erosion;
1.1.4 Impervious surfaces allow less water to percolate into the soil, thereby decreasing groundwater recharge;
1.1.5 Stormwater runoff and concomitant soil erosion and nonpoint source pollution can be controlled and minimized through the regulation of such runoff;
1.1.6 The regulation of stormwater runoff discharges in order to control runoff rates and volumes and nonpoint source pollution associated with stormwater runoff is in the public interest and will minimize threats to public health and safety.
Section 1.2 Purpose
The purpose of this local law 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 Section 1.1 hereof. This local law seeks to meet those purposes by achieving the following objectives:
1.2.1 Require runoff from impervious surfaces to be contained to the maximum extent practicable;
1.2.2 Require land development activities to conform to the substantive requirements of the NYS Department of Environmental Conservation State Pollutant Discharge Elimination System (SPDES) General Permit for Construction Activities GP-02-01 or as amended or revised;
1.2.3 Minimize increases in stormwater runoff from impervious surfaces and land development activities in order to reduce the amount of such water reaching the Sound;
1.2.4 Minimize increases in pollution caused by storm water runoff from impervious surfaces and land development activities which would otherwise degrade local water quality;
1.2.5 Minimize the total annual volume of stormwater runoff which flows from impervious surfaces and any specific site during and following development to the maximum extent practicable;
1.2.6 Reduce stormwater runoff rates and volumes, soil erosion and nonpoint source pollution, wherever possible, through stormwater management practices; and
1.2.7 Ensure that these management practices are properly maintained.
Section 1.3 Statutory Authority
In accordance with Article 10 of the Municipal Home Rule Law of the State of New York, the Village Board of Trustees has the authority to enact local laws for the purpose of promoting the health, safety or general welfare of the Village of Shoreham, and for the protection and enhancement of its physical environment.

Article 3. Administration and Enforcement
Section 3.1 Construction and post-Construction Inspection
3.1.1 Erosion and Sediment Control Inspection
The Stormwater Management Officer may require such inspections as necessary to determine compliance with this law and may either approve that portion of the work completed or notify the applicant wherein the work fails to comply with the requirements of this law and the stormwater pollution prevention plan (SWPPP) as approved. 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 Stormwater Management Officer.
3.1.2 Stormwater Management Practice Inspections
The Stormwater Management Officer is responsible for conducting inspections of stormwater management practices (SMPs). Inspections shall be carried out on a reasonable basis, including but not limited to: 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: 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.
3.1.3 Right-of-Entry for Inspection
When any stormwater management facility is installed on private property or when any connection is made between private property and the public storm water system, the landowner shall grant to the Stormwater Management Officer the right to enter the property at reasonable times and in a reasonable manner for the purpose of inspection as specified in paragraph 3.1.2.
Section 3.2 Enforcement and Penalties
3.2.1 Notice of Violation.
When the Stormwater Management Officer determines that a situation has developed, or an activity is being carried out, not in accordance with the requirements of this local law, he/she may issue a written notice of violation to the landowner, developer or applicant specifying the nature of the violation and a description of the remedial measures necessary to bring the situation or activity into compliance with this local law and a time schedule for the completion of such remedial action.
3.2.2 Stop Work Orders
The Stormwater Management Officer may issue a stop work order for violations of this law. 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 Stormwater Management Officer 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 local law.
Any land development activity that is commenced or is conducted contrary to this local law, may be restrained by injunction or otherwise abated in a manner provided by law.
In addition to or as an alternative to any penalty provided herein or by law, any person who violates the provisions of this local law shall be guilty of a violation punishable by a fine not exceeding three hundred fifty dollars ($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 three hundred fifty dollars nor more than seven hundred dollars ($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 seven hundred dollars nor more than one thousand dollars ($1000) 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 local law 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.
3.2.5 Withholding of Certificate of Occupancy
If any building or land development activity is installed or conducted in violation of this local law the Stormwater Management Officer may prevent the occupancy of said building or land. Such a finding must be communicated to the Building Commissioner in writing, before the Certificate of Occupancy is issued by his/her Office.
3.2.6 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 Stormwater Management Officer may take necessary corrective action, the cost of which shall become a lien upon the property until paid.
Section 3.3 Fees for Services
The Stormwater Management Officer may require any person undertaking land development activities regulated by this law to pay reasonable costs at prevailing rates for review of SWPPPs, inspections, or SMP maintenance performed by the Village or performed by a third party for the Village.
