TABLE 5-C: ISLAND ZONE PURPOSE STATEMENTS
  IR-1   To provide for low-intensity residential, recreational, and rural uses in the less developed areas of the islands
         in order to preserve the rustic character of the islands, to protect groundwater resources and natural and
         scenic areas, and to permit only appropriate low-intensity development in areas lacking adequate public
         facilities and services.
  IR-2   To protect the character of existing developed residential neighborhoods on the islands and to allow infill
         where there are adequate public services. Expansion or extension of an existing IR-2 zone should be strictly
         limited, generally focused toward areas adjacent to existing village IR-2 areas, and restricted by such factors
         as adequacy of access, whether adequate water will be available for private use and for fire protection, and
         whether soils in the area are adequate for subsurface water disposal or whether public sewers are available.
         IR-2 rezoning on substantially sized parcels should not be considered for those sites that should be more
         appropriately zoned otherwise.
  IR-3   To allow for a planned unit development in a manner compatible with both the natural and built
         environment, which provides for adequate circulation and waterfront access, adequate water supply for
         private use and fire protection, and safe and clean disposal of solid and septic wastes. The following
         guidelines shall be considered, among others, in establishing an IR-3 zone:
         A. An IR-3 zone should have a minimum land area of 20 acres.
         B. A site for an IR-3 zone should be able to accommodate higher density development by providing
              buffers from surrounding areas on a substantially-sized parcel for which natural amenities are capable
              of being conserved in a development plan for the site.
         C. IR-3 zones should not be established unless issues of municipal services, including infrastructure,
              education, and police and fire services and other municipal services can be appropriately and
              adequately addressed.
         D. The differences in scale and intensity of uses between existing development and the IR-3 zone, and the
              cumulative impact on the overall density of the island, should be mitigated by appropriate open space
              and buffer areas.
         E. The development plan should have the capability of meeting the development review standards of the
              zone.
   I-B   To provide limited areas on the islands for retail and service establishments that primarily serve the needs
         of the local island market area. CITY OF PORTLAND LAND USE CODE | 5-5 ZONES
