Name: Master Street Plan Amendment — Adding Roundabouts
Location: Jurisdiction wide
Request: Add typical roundabout design as option to the Master Street Plan
Source: Staff
PROPOSAL / REQUEST.-

EQUEST:
To amend the Master Street Plan text to show a 'typical' roundabout design as an
option for road intersections within the Little Rock Master Street Plan area.
ANALYSIS:
Over the last decade 'traffic circles' or'roundabouts' have been used in various parts of
Little Rock for intersection design. These roundabouts were first placed on existing
streets at intersections by the City. Later a few developers placed roundabouts at
intersections of Local and Collector streets. In addition a two lane roundabout was
constructed at an Arterial intersection.
The Master Street Plan does include a 'typical' design for Arterial intersections. This
design has left and right turn lanes for turning movements. It does not include a design
for a roundabout at intersections. To clarify that such an intersection is appropriate in
Little Rock, staff would like to add a 'typical' roundabout design to the Master Street
Plan.
This is intended to be permissive in nature and would still require that the actual design
be reviewed with engineers in the City Public Works Department.
NEIGHBORHOOD COMMENTS:
Notices were sent to the City contact list for ordinance amendments. This list includes
engineers, developers and neighborhood organizations. Staff has received a couple of
calls in general support as a result of the mailing.
STAFF RECOMMENDATIONS:
Staff believes the change is appropriate.

Roundabouts:
Roundabouts can be added to any street of any classification when an engineering
study shows that the proposed round -a -bout will operate at an acceptable level of
service. Round -a -bouts shall be designed in accordance with Standard Engineering
Practice and Guidelines provided by FHWA, AASHTO, ITE, or other applicable
standards. The design shall be submitted to the Department of Public Works for
review and approvals.
