Item 4HCITY OF
SOUTH LAKE
MEMORANDUM
July 7, 2009
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Public Works Director
Subject: Approve Amendment No. 3 to the existing Professional
Services Agreement for design services for the East
Dove Road Drainage Improvements with Teague Nall
and Perkins, Inc. in the amount of $18,900.00.
Action
Requested: Approve Amendment No. 3 to the existing Professional
Services Agreement for design services for the East Dove
Road Drainage Improvements with Teague Nall and Perkins,
Inc. in the amount of $18,900.00.
Background
Information: In January 2008, Teague Nall and Perkins, Inc. was hired to
design the East Dove Road Drainage Improvements. The
professional services agreement included design of a storm
drain system along East Dove Road between North Carroll
Avenue and Dove Creek (just east of Lonesome Dove
Road).
In January 2009, Amendment No. 1 was approved by the
City Manager in the amount of $35,500.00 for the design of
the pavement reconstruction along Dove Rd. between N.
Carroll Ave. and Lonesome Dove Rd. and the addition of
water line improvements at the intersection of N. Carroll Ave.
and E. Dove Rd.
In June 2009, Amendment No. 2 was approved by the City
Manager for design of the extension of a storm drain and the
addition of a portion of 12" water line. The amendment did
not change the total contract amount of $285,100.00.
The current amendment is for the design of an additional
2,800 LF of 12" water line and all related appurtenances
along Dove Road between North Carroll Avenue and
Lonesome Dove Road in the amount of $18,900.
During construction of the Dove Road Intersection and
Drainage Improvements project, it was determined that the
existing water line in Dove Road between North Carroll
Avenue and Kimball Avenue needs to be upsized to a 12"
line to meet the City's Water Master Plan. The water line
from Lonesome Dove Road to Kimball Avenue is also under
design and will be under constructed later this year with
another project. Including the installation of the 12" water
line along Dove Road between North Carroll Avenue and
Lonesome Dove Road while the roadway and storm drain
system are under construction should eliminate the need to
disrupt the area for additional infrastructure improvements
again in the future.
Financial
Considerations: The current amendment to the contract puts the total
amendment amount of $54,400 above the City Manager's
signature authority. Funds for the engineering design of the
East Dove Road Drainage Improvements are included in the
2008 Capital Improvements Program.
Strategic Link: The construction of the water line improvements along Dove
Road with the Dove Road Intersection and Drainage
Improvements project links to the city's strategy map relative
to the focus areas of Infrastructure and Performance
Management and Service Delivery. The specific corporate
objectives that are met by the construction of this water
infrastructure include: Providing High Quality Customer
Service and Investing to provide and maintain high quality
public assets.
