Edmonton City Council agreed to help pay to fix a drainage issue at RE/MAX Field on Wednesday, committing up to $1 million.
A report found that rainwater is not draining away from the field and the bleachers at the city-owned ball park. Water has been leaking into field-level suites.
Baseball Edmonton will contribute more than $600,000 to replace the turf at the park before the 2021 season.
Councillors have now approved a maintenance agreement with Baseball Edmonton to help pay for all of the work.
It includes taking nearly $400,000 from the old Telus Field Capital Reserve.
