[HISTORY: Adopted by the Town Board of the Town of Rye 3-17-1981. Amendments noted where applicable.]
This chapter shall be known and cited as the "Erosion and Sediment Control Ordinance of the Town of Rye."
This chapter is enacted pursuant to the Town's authority to promote the public health, safety and general welfare of its citizenry under the New York State Municipal Home Rule Law, § 10, and the New York State Environmental Conservation Law, Article 36.
The public health, safety and general welfare of the Town of Rye can be adversely affected by flooding, erosion and sedimentation of streams and natural watercourses. The flood hazard areas of the Town are subject to periodic inundation which can result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, public expenditures for flood protection and relief and impairment of the tax base. The Flood Damage Prevention Ordinance,[1] enacted September 25, 1979, addresses this problem. However, erosion and sediment deposition in the waters of the Town increase this flooding, contribute to nonpoint pollution and adversely affect fish and marine life. Therefore, in order to protect the citizens and property of the Town, a program of preventative and remedial activity is required for erosion control and minimization of sediment.

Editor's Note: See Ch. A76, Land Subdivision Regulations, Art. II, Floodplain Management Regulations.
It is the purpose of this chapter to promote the public health, safety and general welfare by:
A. 
Controlling, restricting or prohibiting activities which endanger health, safety or property in times of flood or cause increased flood heights or velocities in watercourses and floodplains.
B. 
Controlling, restricting or prohibiting the alteration of natural floodplains, stream channels and natural protective barriers, including vegetation, which are involved in the accommodation of floodwaters.
C. 
Controlling, restricting or prohibiting land uses and activities which increase nonpoint-source pollution due to erosion and sedimentation.
D. 
Preserving natural resources which aid in prevention of flooding, especially natural vegetation and wetland areas.
E. 
Ensuring that future use of land and water is made in accordance with the most appropriate procedures and principles for control of erosion and sedimentation.

A. 
This chapter shall apply to all municipal permits issued under any law of the Town of Rye or issued by the Town of Rye pursuant to any other law.
B. 
The Town Engineer is hereby designated as the agent for administering and implementing the provisions of this chapter.
C. 
The Best Management Practices Manual of the County of Westchester shall be used as a guide in the issuance of all municipal permits and for all work done pursuant to Town authority.
A. 
Every person seeking any municipal permit for permission to conduct any land-disturbing activity within the Town shall indicate which best management practices he intends to use to minimize erosion and sedimentation caused by that activity. Such applicant shall also list any watercourses which may be affected by the proposed activity or which are within 500 feet of the site of the proposed activity.
B. 
Any municipal permit for land-disturbing activity shall be conditioned by the following provisions:
(1) 
Development shall preserve salient natural features, keep cut and fill operations to a minimum and ensure conformity with topography so as to create the least erosion potential and adequately handle the volume and rate of velocity of surface water runoff as specified in the permit issued by the Town Engineer, based upon the Best Management Practices Manual.
(2) 
Disturbed soils shall be stabilized as soon as practicable and in any event within the time specified in the permit.
(3) 
Temporary vegetation and/or mulching shall be used to protect exposed land areas during development.
(4) 
The permanent (final) vegetation and mechanical erosion control measures shall both be installed within the time specified in the permit.
(5) 
Provisions shall be made to dispose of the increased runoff caused by changed soil and surface conditions during and after development in a manner which minimizes danger of flooding; where necessary, the rate of surface water runoff shall be mechanically retarded.
(6) 
Until a disturbed area is stabilized, sediment in the runoff water shall be trapped by the use of debris basins, sediment basins, silt traps or similar measures, as more specifically may be determined in any particular instance by the Town Engineer.
(7) 
Provisions shall be made to prevent surface water from damaging the cut face of excavations or the sloping surfaces of fills.
(8) 
Cuts and fills shall not endanger adjoining property nor divert water onto the property of others without permission.
