EXHIBIT D: Professional Engineer Letter <br />TRAFFIC UMPACT <br />GROUP, LLC <br />TO: Patrick Marston, Optimal Outcomes <br />FROM: Scott Israeison, P.E., PTOE <br />DATE: 11 May 2020 <br />RE: <br />Required Improvement <br />Medical Office Building TIA <br />Vero Beach, FL <br />Dar Mr. Marston, <br />This letter serves as a reply to your previous email, in which you asked three questions regarding the <br />Vero Beach Medical Office Building Traffic impact Analysis, the docacment's conclusions, and <br />subsequent improvement requirements from Indian River County. <br />(1) Do you stilt disagree with the County's process, assumptions, or conclusions? <br />During our discussions with County staff, our analysis showed that vehicles taming Left out of the <br />development to head north on Indian River Boulevard would experience acceptable levels of service <br />(LOS). This analysis used a two-step left -tum movement that one commonly experiences across <br />divided highways. County staff, however, disagreed with that analysis. Based on a "one-step" left - <br />tam movement, the projected left -turn movement out of the driveway would experience LOS F. To <br />answer your question, there is stilt disagreement between our analysis and County staff. <br />(2) Do you stilt maintain those improvements were not required pursuant to the data, standards, <br />arid processes you typically see in Florida? <br />During our discussions with County staff, t maintained that the exit movement would function <br />acceptably as proposed. However, the County has the authority and responsibility to make <br />requirements of developers and this is no exception. The proposed improvement (left -turn <br />aceeteration Lane), however, is not commonly found in Florida although Isuppose there are some <br />locations where it exists. <br />(3) Do you believe the position the County took was based on "capacity' or "operational" drivers? <br />County staff directed the analysis to examine a "one-step" Left turn out of the development. That <br />analysis resulted in 105 F. The County determined that it was deficient, therefore, the improvement <br />can be considered a "capacity" improvement. <br />Please contact me at scott@traffic-impact.com or by phone at 407.607.6985 with any questions. <br />wkw.trafflc-impact.com <br />2180 West SR 434, Suite 6000, Longwood, FL 32779 1 1 P a g e <br />169 <br />
