Hagen Ranch Road, From the Boynton Canal to the L-22 Canal

Erdman Anthony (as Crossroads Engineering & Surveying) provided highway design and engineering surveying services for the design of this missing link of Hagen Ranch Road through experimental farmlands in Boynton Beach. An interesting aspect of the project was the addition of a roundabout at the future intersection into the adjoining property.

The project was one-quarter mile of a two-lane arterial highway in Boynton Beach expandable to a five-lane facility. It traversed undeveloped farmlands, which required a small amount of fill material (under two feet), connected to an existing bridge over the Boynton Canal, and included the construction of a 72-inch culvert crossing at the L-22 canal. The drainage design involved exfiltration trenches, roadside swales, and an off-site dry detention pond. These facilities were used to meet the regulatory agencies' requirements for water quality and discharge quantities as well as the county's own requirements for roadway flood protection. Surveying services included design surveys, utility pothole locations, location of soil borings, and counter sinking reference points to ensure preservation at this undeveloped site where they were likely to be disturbed.

The county added a roundabout in the center of the project where the future entrance to the adjoining land will be located. The roundabout will provide a pleasant entrance to the property and will aid in calming the traffic through this area, which is primarily residential. The roundabout was designed in accordance with the Florida Department of Transportation guidelines. Since it is one of the few roundabouts designed for Palm Beach County, it will serve as a model for future designs.

The county required an accelerated design schedule; the design was completed in only three phases. Close coordination between the county and (Erdman Anthony) Crossroads project managers enabled the project to be completed ahead of schedule. Additionally, the revision to add the roundabout was completed quickly with only two reviews and permit modification coordination being completed by (Erdman Anthony) Crossroads.
