As a forensic engineering company continues to investigate why the roof drainage system failed at the Adrienne Arsht Center for the Performing Arts during a spring storm, Miami-Dade County Mayor Carlos Gimenez said in a memo Wednesday that the estimated bill for repairs would be about $3.8 million.

A tally of the cost had not previously been released; county commissioners agreed to authorize up to $5 million last month to fix the county-owned center, which opened in 2006. Flooding forced a crowd of nearly 2,500 to flee during a performance of The Lion King in May.

The county pays the Performing Arts Center Trust about $7.65 million annually to cover the facility’s operations and has said that the reimbursements for repairs will likely come from that pot of money as well as other tax-collection funds, if needed.

In the memo, Gimenez said the county, trust and insurance adjusters were continuing to seek reimbursement from insurance carriers. The deductible for the facility is $5 million.

Gimenez also said that a notice of claim has been sent to companies involved in construction or design of the center to allow them to inspect the site and damages. Commissioners have said that they want the county to seek restitution if the damage was due to faulty materials, design or construction.

The county and trust are working to have repairs finished by early October, when the performing arts center’s new season starts.
