[Added 12-16-2014 by L.L. No. 3-2014]
(a) 
Upon the request of an applicant, if the Planning Board makes a finding pursuant to this chapter that the proposed subdivision presents a proper case for requiring trees to be planted for screening or landscaping purposes, but that a suitable location for said plantings does not exist, or it is otherwise impracticable, the Planning Board may permit the applicant to pay a sum of money in lieu thereof. The fee shall be as follows:
[1] 
Not less than an amount as determined by resolution of the Town Board, nor more than an amount as determined by resolution of the Town Board, per tree, based on caliper, that would have been required for screening or landscaping purposes.
[Amended 1-16-2024 by L.L. No. 4-2024]

No subdivision design will be permitted that would create a flood or flooding hazard to adjoining or nearby properties including public roads and property.
A. 
All stormwater runoff resulting from the development or improvement of a subdivision or any of its lots should be retained on-site by adequate on-site drainage structures so that the stormwater runoff will not flow into the right-of-way of a Town, county or state road, upon any neighboring properties under separate ownership, or in any body of water.
B. 
All historic drainage patterns shall be preserved. Where existing grade is altered, the applicant shall submit a grading and drainage plan to the Planning Board. Dewatering, altering, or causing adverse existing drainage patterns and/or conditions on adjacent properties or parcels is prohibited.
C. 
Erosion and sediment control measures as defined by the Planning Board will be required during and immediately after construction on site to help prevent stormwater from carrying soil and other deleterious material onto adjacent properties and highways and into wetland areas and adjoining bodies of water.
D. 
The Planning Board may refer all residential subdivision proposals to the Suffolk County Soil and Water Conservation District (SWCD) and/or the Town Engineering Office, for their review as to the acceptability of proposed drainage, erosion and sediment control measures both during construction phases and after completion. All easements deemed necessary to maintain either natural or man-made stormwater drainage, erosion and/or sediment control measures shall be provided and plotted accordingly on the final plat.
E. 
All subdivisions on parcels greater than 10 acres in size and located within designated watersheds may be required to provide a soil and water conservation plan and/or site development and/or construction best management practices to the Planning Board.
