Yesterday I received the following email from Mr. Gus Pego, FDOT District 6 Secretary:
As you know, at the public information meeting on March 30th for the resurfacing project on Sunset Drive from SW 84th Place to 69 Avenue, the department received numerous inquiries and requests regarding the configuration of the roadway to address the needs of bicyclists.
The design presented at that meeting reflected a minor pavement widening into the roadway median and a reduction in lane width of the inside travel lane in order to implement a wide outside lane in each direction (14 feet in width) to provide a bicycle facility along the corridor. A wide outside lane is one in which the motorist and bicyclist travel in the outside lane together. This meets the requirements of a bicycle facility per the department’s standards.
At the public meeting, the bicycle community requested that the District evaluate an option that would provide a delineated lane for bicyclists.
The department evaluated two different options:
- Implementation of 4 foot undesignated bike lane in each direction
- Implementation of a 5 foot designated bike lane in each direction.
Each of these options would require the addition of significant amounts of pavement to the corridor. As such, new drainage facilities would be needed to treat the additional stormwater runoff resulting from the new pavement areas. Normally french drains would be used for this purpose and environmental permits would be required. Given the project’s close proximity to the South Wellfield protection area, the department’s research indicates that this type of drainage system is not feasible or permittable in this area, although any existing exfiltration trenches or slab covered trenches are “grandfathered-in. Only dry systems for treatment and attenuation (swales or ponds) which would not fit in the corridor without ROW acquisition could be permitted in this area. The additional pavement area would also require the implementation of concrete curb and gutter along the roadway edges due to the proximity to fixed objects along the roadway.
The current project budget is $3.5 Million. The two options cited above are estimated to cost $9.9 Million and $10.1 Million, respectively.
Due to the increased cost and probable drainage permitting issues cited above, the department is not able to implement a 4 foot undesignated bike lane or 5 foot designated bike lane as part of this project. Therefore, the current design of a 14 foot wide outside lane will be maintained; however the department will explore the possibility of installing signing to inform motorists that they need to provide a 3 foot clearance to bicycles and will also explore utilization of special pavement markings.”
