B. 
To meet the requirements of § 99-3 of the Site Design Criteria and Land Development Regulations, and Town Law, the Planning Board may request the reservation and dedication of at least 10% of the area of land to be subdivided for park, playground, recreation, open land or other public purposes. In locating lands to be reserved and dedicated, the Board shall consider preservation of special environmental and geographic features, unsuitability of certain lands for building purposes, future expansion of public use areas, the most appropriate type of public land use for the area and the conditions necessary to preserve access, use and maintenance of such lands for their intended purpose.
C. 
Prior to such lands being dedicated to the Town, a Phase I Environmental Site Assessment shall be completed by the applicant at their expense.
D. 
In the event that the Planning Board, upon consultation with the Town Board, determines that reservation of land of adequate size and suitable purpose cannot be practically located in a proposed subdivision, or that said reservation would not appropriately serve the locale, the Board may condition its approval of a subdivision upon payment to the Town of a sum as set forth by the Town Board. The amount shall be available for use by the Town for neighborhood, playgrounds or other recreation purposes, including the acquisition of property.
A. 
General.
(1) 
It is the Town's intent to control soil movement by employing effective erosion and sediment control measures before, during and after site disturbance.
(2) 
Erosion and sediment control measures, both temporary and permanent, must be designed per the SPDES General Permit and presented for approval to the Planning Board prior to any site development or soil disturbance. A stormwater pollution prevention plan (SWPPP) may be required and shall be prepared in accordance with the NYSDEC requirements and approved by the Town Engineer prior to any site development or soil disturbance.
(3) 
The Planning Board and its designated representatives will evaluate submitted erosion and sediment control design plans against the most current edition of "New York State Standards and Specifications for Erosion and Sediment Control."
B. 
Vegetative controls. To attain the Town's goals, vegetative measures should be used in a site design to control surface water runoff, provide soil stabilization methods and entrap soil sediments generated from the forces of erosion.
(1) 
Site slopes shall be graded to be stable and provide control of any surface or subsurface water prior to vegetative plantings.
(2) 
Site disturbance, especially in sensitive areas, shall be kept at a minimum. Designs shall limit the removal of existing trees, hedge rows and indigenous plant cover. Physiographic features such as drumlins, wetlands and forested areas shall be retained in their natural form.
(3) 
The site developer shall take whatever action is necessary to establish a stabilized vigorous stand of vegetative cover on all disturbed site soils within seven calendar days after construction activities have ceased, unless otherwise authorized in the SWPPP. If phasing is necessary to meet these conditions, the developer shall present such in the development plans presented for Town review.
C. 
Structural controls. Some projects may require erosion and sediment controls that will be permanent in nature. If these measures are required to be constructed, they must be fully functional before upland site disturbance begins as determined by the Town. Such structures may include but are not limited to such features as siltation traps, ponds, diversion swales or dikes.
D. 
Maintenance measures.
(1) 
It is imperative that both the vegetative and structural components as constructed be periodically reviewed and maintained for optimum erosion and sediment control.
(2) 
Facilities must be cleaned, repaired and/or replaced as necessary to meet the original design criteria established in the project approval.
(a) 
Dedicatible projects. If the project under consideration involves possible dedication of constructed facilities to the Town, the developer/owner must include sufficient funds in the maintenance bond to cover the projected cost of such facilities for a two-year period.
(b) 
Private projects. If a project is under consideration without dedicatible facilities to the Town, the site owner is responsible to make sure the erosion control facilities are constructed and properly maintained. Final acceptance of the erosion control facilities is necessary for the Town to issue a certificate of occupancy.
E. 
Penalty. The Town is empowered to assess reasonable penalties to a site owner for failure to properly construct, operate and maintain an approved soil erosion and sedimentation control plan. The penalties shall be as follows:
(1) 
The site owner shall be charged for the Town's costs for, but is not limited to, cleaning ditches, swales, drains or streams that require such due to the failure of the site owner to properly construct, operate and maintain site erosion and sedimentation control devices.
(2) 
No further reviews of such project shall be conducted by the Town until all payments for the Town charges have been satisfied and/or satisfactory completion of the required erosion and sediment control measures has occurred by the site owner.
