20C.30.82 Residential Innovative Zone.
20C.30.82-010 Purpose.
The Residential Innovative zone is intended to achieve the purposes below in addition to those described in the Redmond Comprehensive Plan and Redmond Community Development Guide for Low Moderate Density zones.
(1) Provide a type of single-family housing (smaller dwelling units such as a cottage, size-limited dwelling or duplex) that responds to changing household sizes and ages (e.g., small families, single-person households, retirees).
(2) Provide opportunities for households of various sizes, ages, and incomes to live in a neighborhood by promoting diversity in the size, type and price of new single-family development.
(3) Blend infill development with existing residential development to help maintain neighborhood character, particularly in neighborhoods with a predominance of small to moderately sized dwelling units.
(4) Help to provide appealing and active streetscapes that promote a more walkable and enjoyable neighborhood experience for residents and avoid concentrations of a single housing type or size in one location by interspersing dwellings and lots of various sizes within a residential development. (Ord. 2126)
20C.30.82-020 Applicability.
The Residential Innovative zone may be applied to areas of the City designated Low-Moderate Density Residential. (Ord. 2126)
20C.30.82-030 Density.
(1) Sites 30,500 Square Feet and Greater. Allowed density shall be five dwelling units per gross acre.
(2) Sites Less Than 30,500 Square Feet. Allowed density shall be four dwelling units per gross acre.
(3) Bonus Programs. The allowed density represents the maximum number of dwelling units that may occupy a gross acre of land. This maximum number of units for a site may be exceeded through participation in cottage housing density bonus provisions (RCDG 20C.30.52) or affordable housing requirements (RCDG 20D.30.10) when allowed through a neighborhood plan, or through other bonus programs as provided for in the RCDG. (Ord. 2126)
20C.30.82-040 Requirements for Smaller Dwelling Units.
Applications for subdivisions, short plats, and binding site plans with sites 30,500 square feet and greater shall include smaller dwellings units as a minimum of 20 percent of the greater of: (1) number of proposed dwelling units on the site, excluding cottage housing density bonus or other bonuses, or (2) net buildable area multiplied by the site’s allowed or “zoned” density. See RCDG 20C.30.25-040 for calculation of net buildable area. The smaller dwelling unit(s) shall be a size-limited dwelling as defined by RCDG 20A.20.190, a duplex, or cottage as defined by RCDG 20A.20.030. An existing dwelling on the site that meets the RCDG requirements with regard to size may be counted towards the requirement for smaller dwellings. (Ord. 2126)
20C.30.82-050 Other Site Requirements.
