Collin County voters will decide on an $817.5 million bond proposition this November designed to fund infrastructure upgrades, facility expansions, and public space developments across the fast-growing region.

County commissioners approved placing the multi-part measure on the Nov. 3 ballot to address escalating demand on public resources. Driven by expansion in suburban hubs such as Plano, Frisco, and McKinney, Collin County’s population has reached approximately 1.3 million. Federal census data indicates the county added nearly 43,000 residents between July 2024 and July 2025, ranking it second nationally for annual population growth.

The proposed $817.5 million package was chosen over a smaller $481 million alternative. According to County Engineering Director Clarence Daugherty, the smaller option omitted significant highway funding, jail capacity, and record-storage infrastructure, which would have worsened regional traffic congestion and delayed critical facility expansions.

County Administrator Yoon Kim noted that issuing the full debt package over a six-year period under a conservative 3% annual revenue growth projection could raise the county’s debt service tax rate from 4.18 cents to 4.95 cents per $100 of assessed valuation. However, tax increases are not guaranteed; officials may extend the bond issuance timeline beyond six years or adjust annual sales volumes if local tax revenues outpace projections.

The ballot will feature four distinct propositions:

• Proposition A ($296.5 million): Funds a 550-bed expansion of the county jail alongside facility updates to cell doors, HVAC systems, and elevators. It also allocates funding for courthouse repairs, including roof replacement and department renovations.
• Proposition B ($475 million): Allocates capital for major transportation infrastructure, including service road developments along the Dallas North Tollway, the Outer Loop west of U.S. 75, and a route connecting Farmersville to Rockwall County, alongside general road widening and intersection improvements.
• Proposition C ($6 million): Directs funding toward acquiring land, upgrading existing parks, and supporting joint city-county open-space initiatives.
• Proposition D ($40 million): Authorizes construction of a dedicated facility for the elections department and county records storage, targeted for county-owned land along Bloomdale Road in McKinney.

Commissioner Susan Fletcher emphasized that expanding administrative and judicial space is vital to maintaining basic public services, framing the election as a direct choice for residents on how to manage regional growth challenges.
