Plano City Council approved the final cost for a cast iron replacement project along Park Boulevard at a meeting June 22.
The city also approved the start of a new project in the Parkway Estates and Whiffletree Addition neighborhoods.
In a nutshell
Clay Lipscomb, the city’s community investment program engineering manager, said the first phase of the cast iron pipe replacements along Park Boulevard was completed.
City Council approved $123,492 in additional funds for the project, which spanned from Preston Road to US 75, for a total cost of about $4.7 million, according to city documents. Additional funds approved with council’s change order June 22 include the cost of added pavement replacement, cast iron pipe replacement and other necessities for the project.
“The city has many miles of cast iron water mains. These water mains are old and have an increased likelihood of failure,” said Drew Zaeske, the city’s community investment program manager.
Cast iron pipes that have reached the end of their service life are replaced with PVC water mains, which Zaeske said have a longer service life, are less likely to fail and improve water quality.
The background
The change order was needed to finalize payment for the completed work, per city documents. Funds come from the city’s 2025-26 water Community Investment Program.
City officials first approved work along Park Boulevard July 2024, per previous reporting. Lipscomb said the project was broken down into two phases, with the second phase reaching from US 75 to east city limits.
Lipscomb said the second phase of the project was completed September 2025, while the first phase was completed April 2026.
What’s next
City Council approved more than $5.4 million to start construction for cast iron pipe replacements in the Parkway Estates and Whiffletree neighborhoods.
The project will replace roughly 14,500 linear feet of 6-inch and 8-inch cast iron pipelines, according to city documents. The replacements are needed because of the increased risk of corrosion, line breaks, maintenance costs, service interruptions and negative impacts for residents in the area.
Funding, which comes from the city’s 2025-26 Street Improvements Community Investment Program, will also go toward any needed pavement reconstruction and barrier-free ramp installations during the project.
Lipscomb said construction is estimated to start in July and should be completed by fall 2027.
