Consideration of PSA with Barge Waggoner Sumner & Cannon, Inc., for Aspen Grove Intersection Improvements Project (COF Contract 2015-0196) (08/27/15 CIC 3-0)
body
Purpose
The purpose of this memo is to provide information to the Franklin Board of Mayor and Aldermen (BOMA) concerning a proposed contract for professional engineering services with Barge Waggoner Sumner & Cannon, Inc., for evaluating improvements at the intersection of Aspen Grove Drive and Seaboard Lane.
Background
The intersection at Aspen Grove Drive and Seaboard Lane is currently un-signalized and operates as an all -way stop control intersection. This intersection currently experiences significant delay and queueing along southbound and westbound approaches. This intersection provides access to two apartment complexes - Wyndchase and Park Side apartments. Also, majority of the traffic passing through this intersection is coming from/to Cool Springs interchange at I-65 and accessing the industrial complexes along Seaboard Lane. The current intersection control (i.e., all way stop control) is not able to handle traffic at this intersection and safety of traffic is being compromised. The Aspen Grove Intersection project will evaluate improvements at this intersection for three options (signalization, modern roundabout, mini-roundabout) and come up with conceptual designs and probable costs for each.
Data
BWSC will conduct a Topographic survey to collect right-of-way, utilities, and to identify the adjacent property owners. Also, traffic counts (turning movement counts and tube counts) will be conducted at this intersection. Future year volumes will be calculated using growth rates and considering the future development in the area. ...
