Title
Approving a professional services supplemental agreement with ESP Associates, Inc. in the amount of $1,210,189 for professional engineering services associated with Kelly Lane Phase 3 Roadway Project, and authorizing the City Manager to execute the same.
Summary
This agenda item requests approval of a professional services supplemental agreement (PSSA) #3 in the amount $1,210,188.10 for ESP Associates, Inc. to complete the design for the Kelly Lane Phase 3 roadway improvements project (CIP# TR2001). Prompting this PSSA #3 is a re-design of the Kelly Lane intersections to enhance operations and safety and align the design with the City of Pflugerville’s Transportation Master Plan. The Kelly Lane Phase 3 project extends from just west of Hidden Lakes Drive/Jakes Hill Road to just east of Weiss Lane.
The original design for Kelly Lane Phase 3 assumed signalized intersections at Kelly Lane and Hidden Lakes Drive/Jakes Hill Road and at Kelly Lane and Weiss Lane/Cele Road/Hodde Road. Traffic signals were not warranted nor proposed at the intersections of Kelly Lane with Levels Trail and with Pleasant Bay. The existing Kelly Lane near Weiss Lane was designed to “T” into the new Kelly Lane, with no westbound left turns permitted, effectively making the old Kelly Lane useful only for eastbound Kelly Lane traffic headed to Weiss Lane. No changes were proposed to the old Kelly Lane at Weiss Lane intersection, despite neighborhood concerns with the safety and operational issues associated with making turns at that intersection.
Traffic modeling for the original design using 2040 forecasted traffic indicated levels of service (LOS) D or worse for 10 movements total in the AM and PM peak periods at the intersections of Kelly Lane with Hidden Lakes Drive/Jakes Hill Road, Cele Road/Weiss Lane/Hodde Lane, and old Kelly Lane. LOS qualitatively describes the traffic operations from A to F, with A-C referring to free flow or close to free flow conditions with tra...
