Starleaf Design Ph1 Council Presentation- ExternalStarleaf Pump Station- Phase 1 Design
Agenda Item XXXXX

Our goal is to design and construct a fully redundant supply of treated water with additional storage and pumping capacity.
This allows the City water supply to operate in the event of a pipeline failure and to take the existing pump station off line for maintenance.
Three groups sued the city four and a half years ago contending the city violated the ADA by not doing enough to make sidewalks more accessible. With three cases unresolved, city officials
had said they were unable to move forward on a long-term sidewalk repair plan, even as money for repairs has become available.
“This $1.4 billion settlement is the largest disability access class action settlement in U.S. history” . The settlement, in which the city agreed to spend $31 million a year for 30
years, will install curb ramps throughout the city, fix sidewalks that are broken and torn up by tree roots, install accessible sidewalks and remove many other barriers.

History & Need
In 1999 (or previous) the City outlined the need for additional water pump capacity and redundancy.
The site is owned by the City…….. And is located along the pipeline
The original budget was anticipated to be $10M
The City is currently served by the Village Parkway Pump Station from a 54” Dallas Water Utility pipeline from the Elm Fork Water Treatment Plant.
The City’s historical peak demand is approximately 25 MGD.

Design Firm Selection Process
On April XXX, 2015 a Request for Proposals was advertised for the design of the Starleaf Pump Station
A Selection Committee was formed with City personnel from Fire, Planning and Public Works
Four engineering firms submitted proposals
Three qualified firms were interviewed
Based on interview questions and criteria from the Selection Committee, Brown & Gay Engineers was selected as the design firm

Phased Design
Due to the long-term goals of the project, the Engineering Design & Construction of Starleaf will be broken into four phases.
Phase 1- Site Planning (CURRENT PHASE)
Phase 2- Facility Design
Phase 3- Construction
Phase 4- Commissioning
9
Phase 1
The presentation today covers Phase 1 of the process which includes:
Site Study including Geotechnical and Topographical Information
Hydraulic Models & Feasibility to Assist with Tank Sizing
Recommendations on Pump Selection
SCADA System and Telemetry recommendations
Preliminary Site Layout with Preliminary Construction Cost Estimate
Review and facilitation of Wholesale Water Contracts with DWU and Irving
Phase 1 ($235,000) represents about 20% of the anticipated design budget
