Given the unique shape of the southeast corner of the parcel, maximizing the number of pads in usable sizes was a challenge. Since there is established residential to the west and south and Armstrong Avenue currently ends inside the development, creating an access road that could handle delivery truck traffic was important to making the pads at the end of the street as viable as possible.
Since the site plan is focused on a Build-To-Suit approach to attracting new retailers, it is unknown as to when the back pads will be built out. To accommodate any service traffic to them, a roundabout was installed to allow vehicles to exit easily before being stuck at the end of the street. It also allowed for a median to be placed along the length of Armstrong Avenue, preventing future retail traffic from stopping flow by simply turning across the oncoming lane at any point.
To provide the property owners with a traffic system that would meet future standards given the long timeline for completing the property, Yamabe & Horn designed the roundabout to the 1st Edition of the Federal Highway Administration guidelines. This provided a modern roundabout, as opposed to a simple traffic circle, and increased the likelihood that the road will easily fall within City of Fresno standards well into the future.
The roundabout is 95 feet in diameter and provides enough turning radius for the most common vehicles on the road today.
