M <br />Chairman Eggert moved the discussion to CR -512 landscaping. <br />Public Works Director James W. Davis explained that Phase 2 of CR -512 (the eastern <br />4,000 feet, just west of US -1) is currently under construction. County Engineer Roger Cain has <br />been working with consultants to define the ultimateltypical section of CR -512 west of the <br />Library. A document (preliminary alternative alignment) has just been transmitted which gets <br />into what the actual road should look like. It is necessary now to determine the landscaping <br />element, which involves the width of the median between the eastbound and westbound lanes. <br />He asked that the Commissioners keep in mind that this is a 4 -lane improvement now that will be <br />expandable to 6 lanes in the future. The intent is to install as much of the drainage infrastructure <br />now, so that later the entire cross section of the right-of-way will not have to be re -worked The <br />consultants are mandated by Florida Statutes to use the Florida DOT Uniform Minimum Design <br />Requirements for Streets and Highways (DOT Green Book). He explained how clear zones are <br />established and required under the Green Book. He detailed the differences in the types of <br />roadway designs, a rural (non -curb and gutter) and urban (curb and gutter) and the choice will <br />dictate the right-of-way needed. <br />Director Davis pointed out that other considerations also need to be addressed, such as <br />utility accommodations in the corridor. There is a 20 -inch water main down CR -512 which <br />would end up being placed in the median. Anyone tapping into the water main would possibly <br />have to trench across the median which might disturb the root structure of the trees in the future <br />and also complicate utility maintenance and repair. Another consideration is that, if going with a <br />rural section and expanding the median to 64 feet, there would be additional right-of-way <br />acquisition needed. There are some areas where that will be very sensitive and also some <br />constraints along some of the developed sections. The western part of CR -512 is basically <br />undeveloped now. The design callsfor avoiding disturbing some of the oak canopy around the <br />south prong of the Sebastian River. The roadway is being designed away from it. This <br />particular corridor is much different from the SR -60 and CR -5 10 corridors because much of the <br />property on the north side of the road will be preserved for government or recreational use. <br />More development is likely to occur on the south side of the corridor where landscaping can be <br />designed and be aesthetically pleasing. Curbing the median and introducing large oak trees there <br />would probably inflate the cost of the job by $1-2 million. <br />Director Davis explained that the next concern would be funding for the additional $1-2 <br />million. Phase 1 of the CR -512 corridor was 100% funded with impact fee revenues. It is <br />apparent that the cash flow in the impact fee account will accommodate Phase 2, but the initial <br />estimates and impact fee formula did not include curbing and large tree landscaping in the <br />median. An alternate means of funding would have to be a policy decision. Staffs <br />recommendation is to enhance the corridor and right-of-way with softer vegetation, smaller <br />33 <br />6o0K .�U'.O PAGEJ9L JO <br />JULY 229 1997 <br />
