reviewed by staff, MPO, MPO Advisory Committee, the MPO Technical Advisory Committee and the Planning and Zoning Commission; all recommending approval by the Board. Chairman Ginn thought this was a tortuous way to make a determination. She felt common sense would tell you whether a left-turn lane was needed. She suggested making it a requirement based on a certain number of homes. Discussion continued regarding the process of determination. County Traffic Engineer Chris Mora explained that the developer’s traffic impact study is a requirement and they will use that study to determine trips to and from the development and track trips during peak hours. The benefit of having the guidelines is being able to know where left-turn lanes are needed and there will be more left-turn lanes than we have now. Chairman Ginn said she wants the best system possible. She was concerned that after a development is completed it would be found that a left-turn lane is needed. She believes it would be safer having left-turn lanes a mandatory requirement. Attorney Collins responded that the analysis is based on trips when the development is completed and he thought that should not be a concern. Public Works Director Jim Davis said because left-turn lane projects can be very expensive and to avoid making arbitrary decisions this analysis was prepared by Kimley-Horn and Associates, Inc. Attorney Collins responded to an inquiry made by Commissioner Lowther who asked if the Board can decide on a case-by-case basis. If it is a Planned Development the Board can decide on a case-by-case basis because with Planned Developments the developer can ask for waivers and the Board can ask for additional benefits. If the Ordinance sets out a threshold then, if they meet that threshold, they must put in the left-turn lanes. October 12, 2004 17
