Murphy, Wylie and Sachse residents will vote Nov. 3 on the largest bond package in Collin County history: $817.5 million spread across four propositions to fund roads, a jail expansion, parks and a new elections facility.

The Commissioners Court voted unanimously on Monday, Aug. 10, to place the bond on the general election ballot, choosing the larger of two options after weeks of discussion, the Murphy Monitor reported. The smaller alternative, roughly $481 million, would have cut a major highway project, dropped the elections building entirely and halved the proposed jail expansion, according to The Dallas Morning News.

The package dwarfs the county's previous record, a $683.4 million bond placed before voters across five propositions in November 2023.

What's in each proposition

Proposition A, $296.5 million: Court and detention facility projects, including roughly 550 new jail beds, replacement of cell doors, HVAC upgrades and a courthouse renovation with a new roof and modernized elevators.

Proposition B, $475 million: Road and bridge projects, the largest single share at more than half the total. Planned work includes service roads for the Dallas North Tollway, a second service road for the Outer Loop west of U.S. Highway 75 and a service road from Farmersville to Rockwall County, plus road widening and intersection improvements. The Outer Loop corridor runs near Murphy, Wylie and Sachse.

Proposition C, $6 million: Parks and open space, including land acquisition and joint county-city projects.

Proposition D, $40 million: A new elections department and records storage facility, recommended for the county's 400-acre headquarters on Bloomdale Road in McKinney.

What it could cost taxpayers

The county's current debt service tax rate is 4.18 cents per $100 of assessed property value. If all bonds sell on schedule and revenue grows at 3% annually, that rate could climb to 4.95 cents per $100 over six years.

County administrator Yoon Kim told commissioners the timeline is flexible. "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.

Why now

Collin County added nearly 43,000 residents between July 2024 and July 2025, ranking second nationally among counties for population growth, according to Local Profile. The county now has roughly 1.3 million people.

Commissioner Susan Fletcher pointed to overcrowded facilities. "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," Fletcher said at the Aug. 10 meeting.

Kim initially considered a $1.2 billion package before trimming it to the $820 million range discussed in July and ultimately to the $817.5 million figure approved Aug. 10.

How to vote

The voter registration deadline is Oct. 5, according to county election records. Early voting runs Oct. 19–30. Election day is Tuesday, Nov. 3.
