TABLE 5-C: ISLAND ZONE PURPOSE STATEMENTS
IR-1 To provide for a low-intensity environment characterized by residential, recreational, and rural uses on
Portland’s islands. Standards for the IR-1 zone are intended to preserve and protect the rustic character of the
islands, to protect groundwater resources and natural and scenic areas, and to permit only low-intensity
development in areas lacking adequate public facilities and services. Select nonresidential uses may also be
permitted in the IR-1 zone.

IR-2 To provide for a residential neighborhood environment on Portland’s islands in areas with adequate public
services. Expansion or extension of IR-2 zoning should be limited, generally focused toward areas adjacent to
existing 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, whether soils in the area are adequate for subsurface water
disposal, or whether public sewers are available. Select nonresidential uses may also be permitted in the IR-2
zone.

I-B To provide limited areas on Portland’s islands for the development of a mixture of residential, retail, and
service establishments that primarily serve the needs of the local island market area. The I-B zone provides for
a mixture of commercial and service uses, closely integrated with – and complimentary to – the surrounding
residential neighborhood fabric to support the concept of a complete neighborhood. Standards for the I-B
zone may vary by location, dependent upon the availability of public water and sewer resources.
