Workers with Evans Landscaping, Cincinnati, last week work to demolish the former St. Marys power plant on Chestnut Street near North Street. The company paid the city $198,000 to tear down the building and salvage the scrap metal. The plant was built in the 1920s and generated the city's power for more than 80 years before becoming obsolete and decommissioned in 2008. Demolition began in September and is expected to be completed by the end of the year.
