In the MU-3 Zoning District, the maximum height of any building shall be 45 feet, provided, however, that as part of CDSP approval, the Town Board may permit additional building height where it finds that such additional height, in the context of the development of a project site pursuant to site-specific building envelope controls, furthers the Town's interests in reducing impacts on the environment, including, but not limited to, environmentally sensitive areas, and i) reduces development coverage, and ii) mitigates visual impacts of the proposed development on surrounding properties and viewsheds to a greater extent than a plan restricted to the conforming building height.
(a) A conceptual development plan consistent with the bulk regulations of the MU-3 Zoning District, including the forty-five-foot maximum building height, referred to herein as the "base height plan," shall be provided which reasonably attempts to accomplish the project sponsor's objectives and which shall serve as the baseline for the Town Board's consideration of any alternate conceptual development plan that allows increased building height. The base height plan must conform to all dimensional requirements for the MU-3 Zoning District and to the applicable dimensional requirements of the site development plan regulations and the subdivision regulations of the Town. The base height plan may not be dependent upon variances from, or waivers of, the said Code or regulatory requirements. The base height plan shall consist of the following drawings, all prepared in accordance with the Town's site development plan regulations:
[1] Planimetric Site Layout Sheet (Sheet 1);
[2] Grading, Drainage and Utilities Plan Sheet (Sheet 2); provided, however, that information as to drainage and utilities may be omitted; and
[3] Drawings depicting the masses (height, width, depth) of all buildings proposed for the site. Architectural details such as variations of facade walls, fenestration, door placements, etc., shall not be required for these drawings.
(b) The Town Board may approve an additional building height plan that allows a maximum building height above the maximum allowed by the MU-3 bulk regulations if the applicant demonstrates that the following standards apply:
[1] Compared to the base height plan, there is no increase in floor area ratio.
[2] The maximum increase in permitted height for a building within the building envelope allowed in the CDSP will be no more than one foot for every three feet separating the nearest point of the building and the nearest lot line, and in any event may not exceed 75 feet.
[3] The increased building height does not violate the MU-3 ridgeline protection requirements.
[4] The highest rooftop elevation allowed by the additional building height plan will not be higher than the highest rooftop elevation of the base height plan.
[5] The overall development coverage to be achieved by increasing height must be at least 10% less than the base height plan. The project shall maintain a minimum of 50% of the gross lot area of the subject property as deed restricted open space, which the Town Board may, to the extent feasible, require to be consolidated during the CDSP process, to protect environmentally sensitive areas and to provide contiguous areas of habitat.
[6] All buildings benefiting from increased height must contain at least one level, but not more than two levels, of interior parking within the footprint of the respective building; provided, however, that this parking level requirement shall not apply to any building consisting of a single level with uninterrupted interior volume.
[7] A minimum setback of 200 feet shall be provided between structures greater than 45 feet and the front property line.
[8] The applicant demonstrates to the Town Board, by means of a visual impact analysis or other means acceptable to the Town Board, that the siting of the increased height buildings mitigates visual impacts of the proposed development on surrounding properties and viewsheds to a greater extent than a plan restricted to the conforming building height.
[9] The Town Board shall also consider the potential visual and shadow impacts of any increased height building on nearby off-site structures.
