The plan assessment included updates from the previous 2000 Transportation Plan that were completed before the 2000 US Census data release and prior to completion of the 2030 Charleston Area Transportation Study (CHATS) Long-Range Transportation Plan (LRTP). The 2006 Plan Update used the most up-to-date data available, including 2030 socioeconomic (SE) data projections recently compiled by the Town Planning staff. CHATS is the Metropolitan Planning Organization (MPO) for the region and is responsible for transportation planning. The 2006 Plan Update used the CHATS planning tools and data for initial evaluation of existing and future transportation needs, ensuring consistency with the regional planning process. The study effort refined the regional planning perspective using Town-generated population and employment data for both the 2003 base year and 2030 horizon year to more accurately identify transportation needs. Process Overview The 2006 Plan Update is a multimodal assessment of transportation facilities to include roadways, transit, bicycle, and pedestrian. In every case, accessibility to anticipated multimodal improvements was noted and considered in evaluating road project recommendations. The development of the 2006 Plan Update was completed using existing data sources available from the US Census, the South Carolina Department of Transportation (SCDOT), CHATS, Charleston County and the Town of Mount Pleasant. Coordination with Metropolitan Planning Process The Berkeley-Charleston-Dorchester Council of Governments (BCDCOG) manages the MPO process for the Charleston study area, including the Town of Mount Pleasant. A detailed study and plan was developed for the BCD region in the late 1960s, which formed the basis for the Charleston Area Transportation Study (CHATS). The CHATS area covers the three-county region’s most urbanized parts. Since 1977, BCDCOG has performed the planning and programming functions of CHATS, in collaboration with SCDOT, the Federal Highway Administration (FHWA), and Federal Transit Administration (FTA). The BCDCOG, in collaboration with the South Carolina Department of Health and Environmental Control (DHEC) Bureau of Air Quality (BAQ), is also responsible for regional air quality issues. The BCDCOG region currently meets the requirements for air quality standards and each of the three counties has entered into the statewide Early Action Plan to proactively address possible future air quality issues. The Town of Mount Pleasant is an active member in the BCDCOG Regional Transportation Planning Process. It is represented in all three CHATS committees: Policy Committee (2 of 47 voting members from Town of Mount Pleasant), as well as the CHATS Policy Committee’s two standing advisory committees, the Study Team Advisory Committee (1 of 27 members from Town of Mount Pleasant), and Standing
