Editor's Note: This local law also repealed former Ch. 248, Stormwater Management, adopted 5-4-2004 by L.L. No. 12-2004.
It is hereby determined that:
A. 
Land development activities and associated increases in site impervious cover often after 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 species:
C. 
Clearing and grading during construction tends to increase soil erosion and add to the loss of native vegetation necessary for terrestrial and aquatic habitats;
D. 
Improper design and construction of stormwater management practices can increase the velocity of stormwater ronoff, thereby increasing stream bank erosion and sedimentation;
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 waters of the municipality;
G. 
Stormwater runoff, soil erosion and nonpoint 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 nonpoint 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.
J. 
Trees and woodlands play a vital role in helping to stabilize soil, reducing the risk of soil erosion and siltation in watercourses, and clogging of drainage channels. Additionally, tree roots provide channels that allow water infiltration, crucial to groundwater and reservoir recharge. Woodlands are especially important in carrying out these functions, not just because of the presence of trees, but because the presence of canopy, shrub, and ground cover layers of vegetation. Therefore, protecting the integrity of woodlands and their valuable functions requires regulating the removal of any of these three layers in such communities.
[Added 7-7-2020 by L.L. No. 7-2020]
It is the intent of the Town of Yorktown to establish minimum stormwater management requirements and controls to safeguard persons, protect property, prevent damage to the environment, and promote the public welfare by guiding, regulating, and controlling the design, use and maintenance of any development or other activity which disturbs or breaks the surface of soil or results in the movement of earth on land situated in the Town. 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), 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, 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; and
F. 
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.

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 or the Town Engineer or his/her authorized representative.
B. 
Stormwater management practice inspections. The Town of Yorktown Stormwater Management Officer is responsible for conducting 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.
C. 
Inspection of stormwater facilities after project completion. Inspection programs shall be established on any 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 of 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.

F. 
Special precautions.
(1) 
If at any stage of the grading (at any development site), the Town Engineer or his/her authorized representative determines, by inspection, that the nature of the site is such that further work authorized by an existing permit is likely to imperil any property, public way, watercourse, or drainage structure, the Stormwater Management Officer, Town Engineer or his/her authorized representative may require as a condition of allowing the work to be done that such reasonable precautions be taken as are considered advisable to avoid the likelihood of such peril. Special precautions may include, but are not limited to, reducing the grade of exposed slope, construction of additional drainage facilities, berms, terracing, compaction or cribbing, installation of plant materials for erosion control, and recommendations to use a registered engineer, CPESC individual and/or geologist, which may make requirements for further work.
(2) 
Where it appears that storm damage may result from incomplete grading on any construction site, work may be stopped and the permittee may be required to install temporary structures or take such other measures as may be necessary to protect adjoining property or public safety. On large developments or where unusual site conditions prevail, the Town Engineer may specify the time of start for grading and time of completion or may require that the operations be conducted in specific stages to ensure completion of protective measures or devices prior to the advent of seasonal rains.
A. 
Construction completion guarantee. In order to ensure the full and faithful completion of all land development activities related to compliance with all conditions set forth by the Town of Yorktown in its approval of the stormwater pollution prevention plan, the Town of Yorktown 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 of Yorktown as beneficiary. The security shall be in an amount to be determined by the Town of Yorktown 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 of Yorktown, 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 plans and specifications and that a one-year inspection has been conducted and the facilities have been found to be acceptable to the Town of Yorktown. Per annum interest on cash escrow deposits shall be reinvested in the account until the surety is released from liability.
B. 
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 of Yorktown 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 of Yorktown may draw upon the account to cover the costs of proper operation and maintenance, including engineering and inspection costs.
