Item 4FCITY OF
SOUTHLAKE
MEMORANDUM
April 7, 2009
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Public Works Director
Subject: Approve amendment for design services on F.M. 1709
deceleration lanes to the existing Professional Services
Agreement with Transystems Corporation in the amount
of $7,735.00
Action
Requested: Approve amendment for design services on F.M. 1709
deceleration lanes to the existing Professional Services
Agreement with Transystems Corporation in the amount of
$7,735.00
Background
Information: In December 2006, Transystems Corporation was hired to
design the FM1709 Deceleration Lanes. The professional
services agreement included design of right turn
deceleration lanes at 16 locations along FM1709.
Upon review of the design plans, TxDOT determined that
utilities would need to be relocated at several locations. An
amendment to the contract was approved by the City
Manager in March 2008 in the amount of $48,996.00 to
prepare design plans for the required utility relocations.
During negotiations with a property owner to acquire a
necessary easement, staff agreed to widen an existing
driveway to accommodate ingress/egress to the property
because the deceleration lane design required closure of a
second driveway to the property. The redesigned driveway
will provide similar access to the property as previously
provided by the two driveways. The redesign of the
driveway necessitated the redesign of the sidewalk and
retaining wall to comply with the Texas Accessibility
Standards (TAS) of the Architectural Barriers Act. This
redesign necessitates the proposed amendment.
TxDOT bid letting will be in September 2009 with
construction anticipated to begin shortly thereafter.
Financial
Considerations: The current amendment to the contract puts the total
amendment amount of $56,731 above the City Manager's
signature authority. Funds for the engineering design of the
FM1709 Deceleration Lanes are included in the 1999 Traffic
Management Bond Program.
Strategic Link: The FM 1709 deceleration lane project links to the city's
strategy map relative to the focus areas of Safety and
Security and Infrastructure. The specific corporate objectives
that are met by the implementation of this project include:
Achieving the highest standards of safety and security by
constructing deceleration lanes which provide safe haven for
vehicles which are in the process of exiting the corridor. In
addition, the project assists in providing travel convenience
within the city and region.
