Permits
RC2
Rural Commercial 2 District
There are four types of rural commercial districts. These districts provide for a variety of commercial areas reflecting the diversity of existing business areas. Parcels with this designation that are located within RACs, hamlets, ICIAs, and other areas designated under RCW 36.70A.070 5 d i Dl LAMIRDs shall be principally designed to serve the existing and projected rural population. The county's primary method of such design is to limit building size, height, and floor to area ratios so that businesses of such size and intensity will ordinarily be oriented towards primarily serving the existing and projected rural population. Isolated LAMIRDs D2 and D3 LAMIRDs of a commercial nature are not required to be principally designed to serve the rural population. These isolated commercial LAMIRDs, however, shall protect rural character, which is defined at RCW 36.70A.030 14, by containing and limiting rural development, by not being in conflict with surrounding uses and by assuring that such development is visually compatible with the surrounding area. The county's primary method of achieving such purpose is by providing for buffer yards, limiting the character of rezones, by limiting building size, height, and floor to area ratios in such a way as to be appropriate for the rural areas. Public services and facilities shall not be provided so as to permit low intensity sprawl.
