A. 
On any parcel upon which new construction involving the creation of more than 500 square feet of new impervious surfaces will be created or, in the determination of the Building Inspector, significant additional runoff will be generated, the owner of the parcel shall be required to provide on-site water retention facilities meeting not less than the following criteria.
(1) 
Impervious surfaces. For all new impervious surfaces, the owner shall provide on-site water retention facilities for the full volume of 100% of a five-inch rainfall.
(2) 
All other surfaces. For all other surfaces, the owner shall provide on-site water retention facilities for the full volume of 30% of a five-inch rainfall, as a minimum. Factors to be considered which may warrant an increase in this percentage may include soil conditions, the type of surface coverage, groundwater conditions, and site slope.
B. 
In situations of extreme slopes, grade raises, or other unusual conditions, the Building Inspector and/or the Village Engineer may require greater on-site water retention facilities in order to protect adjacent properties, public roads, and/or waterways and other wetlands.
C. 
In any land development application before it, the Board of Trustees, the Planning Board, the Board of Appeals, the Architectural and Preliminary Site Review Board, and the Landmarks Preservation Commission may require greater on-site water retention facilities in order to protect adjacent properties, public roads, and/or waterways and other wetlands.
[Amended 11-20-2017 by L.L. No. 6-2017]

B. 
All water retention facilities shall be located not less than two feet above the highest reasonably foreseeable potential groundwater level beneath the facilities.
C. 
Adequate soil borings shall be provided to the Village to assure compliance with Subsections A and B.
D. 
All water retention facilities shall be subject to the approval of the Building Department and, in its discretion or when so directed by a Board or Committee of the Village, the Village Engineer.
[Amended 11-20-2017 by L.L. No. 6-2017]
In any land development application before it, the Board of Trustees, the Planning Board, the Board of Appeals, the Architectural and Preliminary Site Review Board, and the Landmarks Preservation Commission may waive the provisions of this chapter based upon the topography, landscaping, existing structures, scope of the proposed work, adjacent properties, groundwater level, soil conditions, cost of implementation, and adverse impacts of failing to provide the water retention facilities set forth herein. Any such waiver shall require the written opinion of the Village Engineer that, in such Engineer's professional opinion, such waiver shall not cause any significant adverse impact upon any adjacent properties, public roads, and/or waterways and other wetlands. Such application shall not be subject to a public hearing; however, notice of such application shall be given to the owners of all of the adjacent properties and such other properties as such board, or commission may deem appropriate by certified mail, return receipt requested, not less than 20 days before the application is to be heard. All of the costs and expenses of such application, including, but not limited to, the fees and expenses of the Village Engineer, shall be paid by the applicant in accordance with Chapter 68.
