SUBJECT: City Manager Approval
ITEM: Consider an action by the City Manager to execute
Supplemental Agreement No. 1 to the Agreement for
Engineering Services with Espey Consultants, Inc. for the
South Creek Channel Improvement Project.
Department: Engineering and Development Services
Staff Person: Michael Thane, Sr. Engineer/Engineering Manager
Justification:
Espey Consultants is designing improvements to channel and drainage systems in
the interest of flood control, appearance, and to facilitate maintenance for the Dry
Branch Tributary No.1 channel that extends from A.W. Grimes Boulevard easterly
through the South Creek Subdivision. A 24 -inch wastewater line currently extends
across the channel where the proposed improvements will occur. Because of
conflicts with the flow lines, the City has requested that Espey investigate
alternative alignments for the existing wastewater line as it crosses Dry Branch
Tributary No. 1.
This Supplemental Agreement No. 1 includes Espey analyzing several alignment
alternatives, including rerouting upstream, use of sag sewers, and installing sag
drains. Espey will design and provide plans, specifications, and a cost estimate
using the selected wastewater alignment from the analysis. Espey will incorporate
the wastewater line design into the existing plans for the channel improvements.
Funding:
Cost: $7,962.00
Source of funds: Capital Project Funds (GO Bond 2001)
Outside Resources: Espey Consultants, Inc.
Background Information:
Dry Branch Tributary No. 1 channel traversing through South Creek subdivision is
difficult to maintain and is critical for carrying flood waters safely through the
subdivision. This same channel is experiencing stabilization problems near its
intersection with Gattis School Road. Also, there have been flooding problems in the
Greenslopes Subdivision just west of Dry Branch Tributary No. 1 near the northern
intersection of Greenlawn Blvd. and Parkside Circle. This project will provide design
of channel improvements that will increase channel capacity and improve the
appearance and maintainability of Dry Branch Tributary No. 1. The City Manager
approved the original agreement with Espey Consultants, Inc. on September 10,
2004.

Work Breakdown Structure
1. Alignment Alternatives Analysis — EC will investigate alignment alternatives for the existing 24"
wastewater line as it crosses Dry Branch Creek. We anticipate analyzing 4 to 5 alignment
alternatives, including rerouting upstream, use of sag sewers, and installing sag drains. Analysis
will also include iterative HEC -RAS modeling of Dry Branch Creek Tributary No. 1 as
necessary. Approximately two project meetings and five conference calls will be necessary to
complete the analysis. EC will verbally recommend a design solution to the City of Round Rock.
No written report will be prepared.
2. Wastewater Line Design — EC will design and provide plans, specifications, and a cost estimate
using the selected wastewater alignment from the previous analysis. EC will incorporate the
wastewater line design into the existing plan and profile sheets; however, additional details and
sections will be required to accurately describe the proposed work. This work will be included in
the next submittal to the City (anticipated to be the 90%). It is anticipated that this design will not
include any additional survey or geotechnical investigations.
