Additional standards for conservation development projects with a combination of dwelling types

Where developments with a combination of single-, two-, three- and multi-family dwellings are proposed in a zoning district where such dwellings are permitted, the following additional requirements shall apply in addition to those provided for herein. If there is a conflict between this subsection and another section of this ordinance, the stricter interpretation shall apply.

• • 1. Permitted uses are limited to: single-, two-, three- and multi-family units. Two-, three- and multi-family uses shall be in the style of duplexes, townhouses with or without attached garages, apartment houses, open space and forestland preserved within open space. Permitted accessory uses include, but are not limited to, a community building, sports and exercise courts and fields, swimming pool, shared gardens and parks and those customarily incidental to a single-family home.

    • a. The number of residential units per structure shall be limited as shown in the table below:

      Structure Type	Maximum Dwelling Units per Structure
      Single-family home	1
      Duplex	2
      Townhouse	4
      Apartment House	8

• • 2. Subject to planning board approval, this form of conservation development project may have greater than one primary residential structure on each lot, without the necessity of obtaining a dimensional or use variance, unless the dwelling is a single-family dwelling.

  • 3. Density. The density calculation for the number of units permitted in this form of a conservation development project shall be calculated as required in section 4 of this article.

  • 4. Lot requirements.

    • a. This form of a conservation development project shall maintain a 75-foot no cut buffer around the perimeter of the entire project excepting for entrance and fire/emergency access points approved by the planning board or other cleared area as required by easement benefiting a utility company, the State of Rhode Island or Town of Tiverton and recorded in the Tiverton Land Evidence Records. This standard may not be reduced by dimensional variance.

    • b. The minimum front yard setback of any single-, two-, or three-family structure from an internal street shall be 30 feet; for a multi-family structure the minimum front yard setback shall be ten feet. The minimum setback between any two structures shall be 20 feet. The minimum setback from the no cut buffer shall be 20 feet.

      • (1) These setbacks are subject to approval by the town engineer and Tiverton Fire Marshal for safe access and operation of vehicles, emergency vehicles, and pedestrians. The planning board, based on competent evidence, may require plan modification including an increased setback to achieve public safety requirements.

      • (2) This standard may not be reduced by dimensional variance.

  • 5. Water and wastewater. All projects of this form that include multi-family dwellings of four units or more must be served by public water and public sewer.

  • 6. Sidewalks shall be required along at least one side of all internal streets. Where there are existing sidewalks on the primary road, a sidewalk shall be required to connect.
