Berkeley County completed a scenario planning and likely impacts analysis to accompany its new 2040 Comprehensive Plan, One Berkeley. It contemplated four alternative growth scenarios for a county-wide planning area, measured their impacts, and evaluated the trade-offs between them for meeting stated goals for the community. The scenarios were also used to enumerate infrastructure and financial impacts associated with the four different conservation and development futures, which will influence the creation of a Future Land Use Map for the new Comprehensive Plan. Findings and conclusions in the report that are focused on government finances, future land use categories, supporting infrastructure, and the costs of providing services will also be considered for specific policies and recommendations in the new Comprehensive Plan. The Scenario Planning and Likely Impacts Analysis Report presents information for Unincorporated Berkeley County and the cities and towns within it separately. The information for Unincorporated Berkeley County is highlighted in different report chapters, which will be considered while developing the new Comprehensive Plan. Information for nine individual cities and towns within Berkeley County is presented in the technical appendix of the report, and is available to the individual jurisdictions for their use independent of the County’s initiative to write its new Comprehensive Plan. The Report is organized into seven chapters: General Overview — A brief overview of the planning area, key concepts, and the work completed for the scenario planning and likely impacts analysis. Methodology and Tools — A summary of four primary components developed to support 1 | Berkeley County, SC
