A. 
District purposes.
(1) 
General purposes of all residential districts. The residential zoning districts contained in this section are intended to:
(a) 
Provide appropriately located areas for residential development that are consistent with the Dobbs Ferry Vision Plan and with public health, safety, and general welfare;
(b) 
Allow for a variety of housing types and community amenities that meet the diverse physical, economic, and social needs of residents; and
(c) 
Respect the scale and character of existing residential neighborhoods and surrounding areas.
(2) 
Specific purposes of residential districts.
(a) 
One-Family Residential (OF) Districts. The primary purpose of the OF Districts is to maintain the character and scale of established neighborhoods characterized by one-family houses on individual lots and to allow for the appropriate development and redevelopment of lots in those areas. Clustered development may be appropriate in some areas with OF designation. The Zoning Ordinance provides a range of OF Districts (OF-1 to OF-6) which are differentiated primarily on the basis of minimum lot area and coverage requirements.
(b) 
Mixed-Density Residential (MDR) Districts. The primary purpose of the MDR Districts is to maintain the character and scale of established neighborhoods characterized by a mixture of detached one-family houses, two- and three-family homes, and multifamily housing, often found in large, older buildings which have been reorganized into apartments, and to allow for the appropriate development and redevelopment of lots and existing buildings in those areas. The districts are also intended to provide a transition between OF Districts and higher-density apartment districts or commercial districts. The Zoning Ordinance includes three types of MDR Districts intended to address the current and desired character of different areas of the Village.
[1] 
MDR-1 allows for a mixture of one-, two- and three-family dwelling units and townhouses with a minimum lot area of 2,500 square feet per dwelling unit is required. See Appendix B, Table B-2.[1]
[1]
Editor's Note: Appendix B is included at the end of this chapter.
[2] 
MDR-2 allows for a more intense mixture of dwelling units, including townhomes and small multifamily buildings with a maximum of eight units per building. A minimum lot area of 800 square feet per dwelling unit is required. See Appendix B, Table B-2.[2]
[2]
Editor's Note: Appendix B is included at the end of this chapter.
[3] 
MDR-H is intended to reinforce the existing pattern of larger historic homes and estates that have been subdivided into multiple dwelling units while maintaining the exterior appearance of a single-family home. A minimum lot area of 2,500 square feet per dwelling unit is required. See Appendix B, Table B-2.[3]
[3]
Editor's Note: Appendix B is included at the end of this chapter.
(c) 
Multifamily (MF) Districts. The primary purpose of the MF Districts is to maintain the character and scale of existing multifamily housing complexes. Although the districts accommodate a wide range of housing types, they are primarily intended to accommodate moderate- to high-density, multiunit residential buildings in areas where such development already exists. The Zoning Ordinance includes four MF Districts (MF-1, MF-2, MF-3 and MF-4). These districts are differentiated primarily on the basis of allowed density (minimum lot area per unit).
(d) 
Broadway (B) District. The purpose of the Broadway (B) District is to support the continued use of large homes, many built pre-1900, for multifamily and professional offices. Adaptive reuse that retains the historic character of the existing buildings is encouraged.
B. 
Conformance with design and character guidelines.
[Amended 7-13-2021 by L.L. No. 3-2021]
(1)

A. 
District purposes.
(1) 
General purposes of all downtown districts. The downtown districts are intended to accommodate retail, service, residential and commercial uses and to ensure that business and commercial-zoned areas are compatible with the character of existing neighborhoods. The downtown districts are also intended to ensure the preservation of the unique character and quality of life in the downtown area by encouraging compatible redevelopment and infill development.
(2) 
Specific purposes of commercial districts.
(a) 
Downtown Business (DB) District. The purpose of the Downtown Business (DB) Zoning District is to maintain the existing character, scale and mix of uses in the downtown core that allow it to serve as the Village's meeting place while encouraging appropriate redevelopment that adds to the civic and economic vitality of the community. A mix of uses, including residential uses above nonresidential establishments, is encouraged. In order to encourage a pedestrian-friendly environment, flexible standards are provided for meeting parking requirements.
(b) 
Downtown Transition (DT) District. The purpose of the Downtown Transition (DT) Zoning District is to maintain the existing character, scale and mix of uses along Lower Main Street (below the Library) as a transition between the more intensive Downtown Business District and the surrounding residential areas. Residential uses are permitted on both the ground floor and above nonresidential establishments. In addition, the DT Zoning District may be applied to other commercial areas that serve surrounding residential neighborhoods.
(c) 
Gateway (DG) District. The purpose of the Downtown Gateway (DG) Zoning District is to provide an appropriate location for community- and region-serving commercial within a mixed use environment near the intersection of Ashford and Broadway; to enhance the pedestrian environment; to reduce traffic conflicts; and to encourage development including residential uses with a quality of design appropriate for this highly visible location. Development should be focused to the major streets, with transitions in building scale, intensity and use adjacent to established residential neighborhoods.
B. 
Downtown design guidelines. Conformance with the Downtown Design Guidelines in Appendix F,[1] as adopted by the Board of Trustees, is encouraged and shall be considered as part of the site plan review criteria, as well as a basis for the Architectural and Historic Review Board's evaluation.
[1]
Editor's Note: Appendix F is included at the end of this chapter.

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
C. 
Chauncey Park (CP) District.
(1) 
District purpose. The purpose of the Chauncey Park (CP) Zoning District is to facilitate redevelopment opportunities in the area of the Village bordering the Saw Mill Parkway immediately north and south of Lawrence Street. The area was originally a small hamlet served by the Putnam train line with a station at Lawrence Street. Because of its remote location relative to the remainder of the Village and its excellent access to the regional roadways, the area is particularly appropriate for larger-scale redevelopment as a mixed use center with substantial employment and mid- to high-density residential opportunities. New construction in the CP District shall meet standards for cluster development, with a site design that is sensitive to the environmentally sensitive features in the area, including wetlands and watercourses, steep slopes, and woodland areas, and that takes advantage of opportunities for trail connections, sidewalks and greenbelts. In addition, building design should reflect the modernist architectural style of existing buildings. As the area represents a prime development opportunity in the Village, all plans will be held to the highest standards of site design, architecture and green building.
(2) 
Cluster development mandated. In order to allow for additional flexibility in site and building design while ensuring the highest quality development with significant community benefits, any redevelopment of portions or the entirety of the CP zoned property that includes the subdivision of properties or the development of new structures shall be consistent with the standards for cluster development in Article XIII, § 300-54F.
(3)

(6) 
Development incentive bonus in the Chauncey Park District. In order to further the objectives of the LWRP and the Vision Plan, the Board of Trustees in consultation with the Planning Board may increase the permissible density of development in the Chauncey Park District as set forth below:
[Amended 6-14-2011 by L.L. No. 6-2011]
(a) 
The Board of Trustees may provide, in its sole discretion, density bonuses in accordance with this subsection in exchange for an applicant providing one or more of the following facilities or amenities:
[1] 
Preserving environmentally sensitive features such as steep slopes, rock outcroppings, watercourses and stands of trees;
[2] 
Implementing stormwater management measures that improve the water quality in wetlands and help prevent flooding of the Saw Mill River Parkway;
[3] 
Committing a significant portion of land in the Chauncey Park District to park or open space use, either by conveying the land in the Chauncey Park District to the Village for such purposes or by other means, such as covenants, deed restrictions, and/or conservation easements;
[4] 
Promoting walking and biking trails that help connect sidewalks and off-site trails through the Chauncey Park District to neighboring communities' parkland, the Putnam bike trail, and Hillside Park;
[5] 
Improving vehicular traffic patterns and connections to adjacent street networks through the Chauncey Park District to reduce congestion;
[6] 
Encouraging the use of mass-transit for people visiting, working or living in the Chauncey Park District;
[7] 
Providing a shuttle bus system connecting the Chauncey Park District to the downtown portions of the Village of Dobbs Ferry and the Metro North Station;
[8] 
Preserving a significant portion of the existing structures in the Chauncey Park District;
[9] 
Providing a mix of residential unit sizes (e.g., one-bedroom and two bedroom units) in development to be constructed in the Chauncey Park District that is consistent with the needs of the Village; and
[10] 
Achieving a LEED-ND rating for the development within the Chauncey Park District, although actual certification is not required.
(b) 
For applicants who provide or make provision for amenities and facilities listed in § 300-37C(6)(a) above, the Board of Trustees may, at its discretion, award bonuses by increasing the density ratios in Chauncey Park District up to a maximum of 20%. A bonus awarded under this provision may be in any increment between 0% and 20% in proportion to the degree to which the proposed amenities confer benefits identified in § 300-37C(6)(a) above, and shall be computed by reducing the minimum size of plot per family by the amount of the bonus. For example, if a bonus of 10% were allowed, permissible density would be calculated based on a reduction of the minimum lot per family from 1,800 square feet to 1,620 square feet. The bonus permitted under this section is a bonus in permissible density only and does not authorize any enlargement of the permissible bulk or lot coverage of buildings to be constructed.
(c) 
In awarding a density bonus under this subsection, the Board of Trustees shall make specific findings that set forth in detail the amenities to be provided by the applicant, how those amenities further the purposes of the LWRP and the Vision Plan and, in particular, how they preserve and enhance the unique aesthetic, recreational, environmental and historic qualities and features of this district for the maximum benefit and enjoyment of the entire community and otherwise promote the public health, safety and welfare of the community. The findings shall also set forth in detail the relationship between the amenities being provided and the bonus being awarded and shall specify the rationale supporting the proportionality of the amenities to the bonus.
D. 
Educational/Institutional (EI) District.
(1) 
District purpose. The purpose of the EI District is to accommodate the development of public or quasi-public facilities or private facilities of a noncommercial character, including churches, hospitals, schools and cultural facilities in a campus-like setting with substantial open space. The Ardsley Country Club, while an existing private facility, is included within this district because of similar land use impacts and the campus-like setting of the facility. The Dobbs Ferry Hospital, while it does not include substantial open space, is included within this EI District specifically because it is a large public facility with a property that is incongruent with its surrounding residential neighbors, requiring better control of the uses of that property and their impacts on the surrounding community. Because of the size of the EI zoned lands and the potential for significant impacts on surrounding properties and the community as a whole, redevelopment and subdivision applications shall meet the cluster development standards. In order to permit a comprehensive understanding and review of future development potential, a plan illustrating the property owner's development and disposition plans for the site should accompany any such application.
(2) 
Cluster development mandated. In order to allow for additional flexibility in site and building design while ensuring the highest quality development with significant community benefits, any redevelopment of portions or the entire parcel in the EI zone that includes the subdivision of properties or the development of new structures shall be and are mandated to be consistent with the standards for cluster development in Article XIII, § 300-54F.
(3) 
Development plan required. Any application for subdivision or development shall include a graphic plan and accompanying text illustrating the property owner's long-term plan for the development and disposition of the site. Such plan should, at a minimum, indicate proposed roadway and pedestrian path alignments, open space and sensitive natural areas/features, areas identified for disposition, and proposed uses, densities and building heights. Where a rezoning application is anticipated for a portion or the entirety of the site, the preferred zoning designation should also be indicated. Such plan shall not constitute an application for rezoning.
(4) 
Permitted uses. Permitted uses in the EI Zoning District shall be as specified in Table A-3.[10]
[10]
Editor's Note: Table A-3 is included at the end of this chapter in Appendix A.
(5) 
Dimensional standards. Dimensional standards in the EI District shall be as specified in Table B-10.[11]
[11]
Editor's Note: Table B-10 is included at the end of this chapter in Appendix B.
(6) 
Base density. The base permitted density for development within the EI District is per 40,000 square feet. That density may be increased according to the standards for cluster development at Article XIII, § 300-54F, and the findings of the site plan review.
