Collin County commissioners voted 4-0 Monday to call a November bond election that would authorize $817.5 million in infrastructure projects to keep up with the breakneck speed of growth in their county, which is home to Dallas suburbs such as Plano, Frisco and McKinney.
The county, now home to about 1.3 million people, ranked second in the country for counties that added the most residents in a year. It added nearly 43,000 new residents between July 2024 and July 2025, according to U.S. Census numbers.
The bond is broken down into four propositions that residents will vote on Nov. 3. Proposition A sets aside money for expansion of the county jail and courthouse. Proposition B will fund road and bridge projects. Proposition C will pay for park and open space projects. Proposition D will allow the county to build a new facility for the elections department and the storage of county records.

Commissioner Duncan Webb, who represents the southwest part of the county, was absent from Monday’s vote.
Commissioner Susan Fletcher, who represents parts of Frisco, Prosper and Celina, said the bond, especially funds for the courthouse’s expansion, would help the county serve residents more efficiently.
“I don’t like to hear … about the long lines at the tax office and people sitting on the floor,” Fletcher said. “We’ve got to respond to the growth.”

Commissioners on Monday discussed two proposals and chose to put the larger bond package on the ballot instead of one worth about $481 million. The smaller proposal did not include a major highway project, funds for the elections building or half of the beds proposed in the county’s jail expansion. That proposal also included less than 60% of the funds set aside for transportation in the larger bond commissioners chose to put on the ballot.

“It’ll delay the projects that are addressing congestion,” Clarence Daugherty, director of engineering for the county, said of the smaller proposal.
The $817.5 million bond could raise the debt service rate from 4.18 cents per $100 of assessed value to 4.95 cents per $100 of assessed value over six years, which could increase taxes. During discussions before the vote, County Judge Chris Hill said he was weighing the long-term impacts of the proposed bond.
“I really like the idea of holding the … rate steady,” Hill said. “But I recognize that all these projects are really important, and as we put them off … we defer them for the future.”

Fletcher said it would ultimately be the voters’ decision whether to fund these projects through a bond now or deal with the impacts such as traffic or paying for inmates to be transported to other counties when the jail hits capacity.

“If the taxpayers choose to go forward, we go forward. If they don’t … we’re still going to pay [in other ways],” Fletcher said.
Here’s a breakdown of the four propositions:
Proposition A
This $296.5 million proposition includes expanding the county jail by approximately 550 beds, replacing cell doors, modernizing elevators and upgrading HVAC systems, county administrator Yoon Kim said. About a third of this proposition will fund improvements to the county courthouse building including replacing the roof, modernizing elevators and renovating the space that currently houses the community supervision and corrections department.
Proposition B
This $475 million proposition could fund three major road projects. These include service roads for the Dallas North Tollway, the second service road for the Outer Loop just west of U.S. Highway 75 and a service road from Farmersville to Rockwall County, Daugherty said. Money will also be used to widen existing roads and improve intersections.

Proposition C
This proposition dedicates $6 million to parks and open space projects. This includes acquiring land, improving existing parks and joint county-city projects.
Proposition D
This proposition will fund a new $40 million facility for the elections department and the storage of county records. Kim said if voters approve the proposition, staff recommends constructing the facility at the county’s headquarters on Bloomdale Road in McKinney, where the county owns 400 acres and wouldn’t have to buy new land.
