Final costs to repair a cracked roof truss in the Sagebrush Theatre are expected to exceed $1 million once final invoices are calculated.
The bill figures to be about $200,000 more than initially estimated when the damage was discovered earlier this year.
SD73 facilities director Art McDonald said the city and SD73 are working out how to divvy up the costs of repairs.
The two entities have a cost-sharing agreement regarding capital items for the Sagebrush Theatre.
A cracked roof truss was discovered in February, leading to an eight month shutdown in the facility that left arts groups in the city scrambling.
A new steel structure was added in the roof to support the beams and the truss repaired.
