Measure O on the Nov. 3, 2026 ballot asks voters in the Reed Union School District — covering Tiburon, Belvedere and east Corte Madera — whether to authorize $115 million in general-obligation bonds to repair and upgrade all three campuses: Reed and Bel Aire elementary schools and Del Mar Middle School. The ballot question estimates about $6.2 million a year in debt service while bonds are outstanding. It needs 55% approval.

What a yes or no vote means

A yes vote authorizes the district to sell up to $115 million in bonds at legal interest rates for projects on the bond Project List. A no vote leaves the district without that borrowing authority; board President Shelby Pasarell Tsai told The Ark that unmet facility needs would then have to come from the district's operating budget, which could mean staffing or program cuts.

By law, bond proceeds cannot pay teacher or administrator salaries. The measure requires a citizens' oversight committee and annual independent audits. County Counsel's impartial analysis says money may only be used for the listed facilities purposes, including bathrooms, plumbing, roofs, fire and earthquake safety, and mold and asbestos removal.

What it would cost property owners

The tax rate statement, signed by Superintendent Kimberly McGrath, estimates an average rate of $26.63 per $100,000 of assessed value over the life of the bonds, with a highest projected rate of $30 per $100,000 in fiscal 2027-28. The last collection year is estimated as 2060-61. Total principal and interest if all bonds are sold is estimated at $213 million. Rates are based on assessed value, not market value.

The Ark notes that for every $1 million of assessed value, the peak rate works out to about $300 a year.

What the money would fix

The average campus age is about 68 years; Reed School dates to 1954, according to the argument in favor. Supporters cite leaking roofs, worn clay-pipe plumbing, outdated electrical and HVAC systems, and portable classrooms with mold. At Bel Aire, some portables have been closed as unsafe; at Reed and Del Mar, portables still house programs such as prekindergarten and robotics, district leaders told The Ark.

Planned work includes replacing portables with permanent classrooms, installing air conditioning districtwide, removing hazardous materials, and site-specific repairs such as covered lunch areas, playground paving and accessibility upgrades beyond ADA minimums. The district's long-range facilities plan, finished in 2024, would guide priorities. Tsai said $115 million still falls short of every need and that the board does not plan a second bond.

Who is for and against

The argument in favor was signed by Tsai, PTA President Jessica Etchevers, former board member A.J. Brady, Belvedere Councilmember Jane Cooper and Tiburon Councilmember Jack Ryan. No argument against Measure O was filed with Marin County Elections.
