BEFORE THE ADOPTION OF Washington State’s Growth Management Act (GMA) in 1990, unincorporated communities like South Hill were under the planning and development policies of Pierce County’s Comprehensive Land use Plan and the Pierce County Zoning code adopted in 1962. Basic Euclidian zoning districts were established that dictated the appropriate location for commercial business and residential homes. However, the Plan did not offer much protection from incompatible uses and did not recognize the unique individuality of communities. The lack of contemporary design guidelines and community involvement is evident on Meridian Avenue (SR-161), the main thoroughfare of South Hill. Rapid growth during the late 1970’s caused major traffic congestion as it became intensely developed as a continuous strip of commercial developments.
