It is hereby determined that:
A. 
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.
B. 
This stormwater runoff contributes to increased quantities of waterborne pollutants, including siltation of aquatic habitat for fish and other desirable habitat.
C. 
Clearing and grading during construction tend to increase soil erosion and add to the loss of native vegetation necessary for terrestrial and aquatic habitat.
D. 
Improper design and construction of stormwater management practices can increase the velocity of stormwater runoff thereby increasing stream bank erosion and sediment.
E. 
Impervious surfaces allow less water to percolate into the soil, thereby decreasing groundwater recharge and stream base flow.
F. 
Substantial economic losses can result from these adverse impacts on the water of the municipality.
G. 
Stormwater runoff, soil erosion and non-point-source pollution can be controlled and minimized through the regulation of stormwater runoff from land development activities.
H. 
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 non-point-source pollution associated with stormwater runoff is in the public interest and will minimize threats to public health and safety.
I. 
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 Village of Plandome Manor and to address the findings of fact in § 104-1 hereof. This chapter seeks to meet those purposes by achieving 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.
C. 
Minimize increases in stormwater runoff from land development activities in order to reduce flooding, siltation, increases in stream temperature and stream bank erosion and maintain the integrity of stream channels.
D. 
Minimize increases in pollution 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 the maximum extent practicable.
F. 
Reduce stormwater runoff rates and volumes, soil erosion and non-point-source pollution, wherever possible, through stormwater management practices and to ensure that these management practices are properly maintained and eliminate threats to public safety.
A. 
This chapter shall be applicable to all land development activities as defined in this chapter, Article II, § 104-5.
B. 
The Village of Plandome Manor shall designate a Stormwater Management Officer who shall accept and review all stormwater pollution prevention plans and forward such plans to the applicable Village board. The Stormwater Management Officer may:
(1) 
Review the plans.
(2) 
Accept the certification of a licensed professional that the plans conform to the requirements of this chapter.
C. 
All land development activities subject to review and approval by the Planning Board of the Village of Plandome Manor under subdivision and site plan regulations shall be reviewed subject to the standards contained in this chapter.
D. 
All land development activities not subject to review as stated in Subsection C shall be required to submit a stormwater pollution prevention plan (SWPPP) to the Stormwater Management Officer, who shall approve the SWPPP if it complies with the requirements of this chapter.
The following activities may be exempt from review under this chapter.
A. 
Agricultural activity as defined in this chapter.
B. 
Routine maintenance activities that disturb less than one acre and are performed to maintain the original line and grade.
[Amended 7-15-2008 by L.L. No. 3-2008]
C. 
Repairs to any stormwater management practice or facility deemed necessary by the Stormwater Management Officer.
D. 
Any part of a subdivision if a plat for the subdivision has been approved by the Village of Plandome Manor on or before the effective date of this chapter.
E. 
Land development activities for which a building permit has been approved on or before the effective date of this chapter.
F. 
Installation of fence, sign, telephone and electric poles and other kinds of posts or poles.
G. 
Emergency activity immediately necessary to protect life, property or nature resources.
H. 
Activities of an individual engaging in home gardening by growing flowers, vegetables and other plants primarily for use by that person and his or her family.
I. 
Landscaping and horticultural activities in connection with an existing structure that open not more than one acre of area.
