ChapterONEEXISTING CONDITIONS1.1 STUDY PURPOSEThe Ohio Kentucky Indiana Regional Council of Governments (OKI) and DearbornCounty undertook the Dearborn County Transportation Assessment in April of 2003.Dearborn County is one of the fastest growing counties within the OKI region. With apopulation of nearly 46,000 in 2000, Dearborn County is expected to grow by 60% by2030, according to the 2030 OKI Regional Transportation Plan. In fact, also accordingto OKI, over 90% of the region’s growth in the next 30 years will occur in the outer belt ofCincinnati that includes the counties of Butler, Clermont, Warren, Dearborn and Boone.The Dearborn County Transportation Assessment project comes at an opportune time inthe county’s history. The county is benefiting from its proximity to the Cincinnati urbancore and from the success of tourism attractions such as Argosy Casino and PerfectNorth Slopes. The triangle between I-74, I-275 and SR 1 is being rapidly developed andincludes the communities of St. Leon, Bright, Hidden Valley Lake, Greendale,Lawrenceburg and Aurora. While residential and commercial development is on the risewithin Dearborn County, the infrastructure still remains mostly rural. Many of thecounty’s rural roads were not designed to operate under increased volumes. Severalroadways now serve thriving communities but are too narrow and do not meet currentstandards. The infrastructure of the area needs to be improved to accommodate theexisting and future needs of Dearborn County.The Transportation Assessment will provide Dearborn County with a framework forfuture projects and will include a complete evaluation of the county roadwayinfrastructure. This chapter will provide background data regarding the socioeconomic,transportation, and land use description of the study area. This information will be usedto identify and understand the existing problems and issues in the area. It also helpedshape the development of a wide array of initial alternatives.Study GoalsAfter discussions with the Project Management Team, consisting of Dearborn County,OKI and Parsons Brinckerhoff, and an examination of the needs of Dearborn County, thefollowing goals have been developed for the Transportation Assessment.1. The Dearborn County Transportation Assessment will identify a responsible planfor roadway maintenance and spending within the county. This goal willencompass identifying an accurate roadway mileage count to be filed with thestate of Indiana to receive appropriate funding as well as set a prioritizationprocedure for roadway maintenance.2. The Dearborn County Transportation Study will provide an accurate blueprint ofthe county roadway system to assist in understanding the growth trends of thecounty and its future transportation needs.Dearborn County Transportation Assessment Page 1-1
