Allen-area voters will decide Nov. 3 whether to approve $817.5 million in Collin County bonds split across four propositions covering jail and courthouse expansion, roads, parks and a new elections facility.

The Collin County Commissioners Court voted 4-0 on Aug. 10 to place the package on the general election ballot. Commissioner Duncan Webb was absent. The six-year program, covering fiscal years 2027 through 2032, exceeds the county's $683 million bond package voters approved in November 2023.

Here's what each proposition would fund, according to The Dallas Morning News:

Proposition A ($296.5 million): Jail and courthouse projects. About 550 new beds at the Collin County Detention Facility in McKinney, which has been operating at or above capacity and forcing the county to board inmates elsewhere. Roughly one-third of the money goes to courthouse improvements including a new roof, elevator upgrades and renovation of the community supervision space.

Proposition B ($475 million): Road and bridge projects. Includes service roads for the Dallas North Tollway, a second service road for the Outer Loop just west of U.S. Highway 75 and a service road from Farmersville to the Rockwall County line, plus widening existing roads and improving intersections.

Proposition C ($6 million): Parks and open space, including land acquisition, improvements to existing parks and joint county-city projects.

Proposition D ($40 million): A new facility for the elections department and county records storage. Staff recommends building it on Bloomdale Road in McKinney, where the county owns 400 acres.

Tax impact

County officials said the bond could raise the debt service rate from 4.18 cents per $100 of assessed value to as much as 4.95 cents over six years, assuming county revenue grows 3% annually. County Administrator Yoon Kim said a tax increase is not guaranteed. "There's multiple factors. We don't have to sell it all over six years. It can be seven or eight to try to maintain today's tax rate as much as possible," Kim said at the Aug. 10 meeting.

Commissioners chose the larger of two options. The smaller, roughly $481 million package would have excluded the elections building, cut proposed jail beds in half and funded less than 60% of the transportation projects. Collin County Director of Engineering Clarence Daugherty told commissioners the smaller option would delay "the projects that are addressing congestion."

Growth driving the ask

Collin County now has about 1.3 million residents. It ranked second nationally among counties adding the most people in a single year, gaining nearly 43,000 residents between July 2024 and July 2025, according to U.S. Census data.

Commissioner Susan Fletcher framed the vote in practical terms at the Aug. 10 meeting: "I don't like to hear … about the long lines at the tax office and people sitting on the floor. We've got to respond to the growth."

Allen voters will also see a separate $600 million Collin College bond on the same Nov. 3 ballot, meaning more than $1.4 billion in combined borrowing decisions.
