Renderings of Commercial Buildings Proposed in Columbia submitted to the TC Planning Comission Columbia, CA — There was a contentious debate over water services for the planned Stone Mill Center near Columbia. The TUD Board of Directors discussed whether to approve the CEQA Notice of Determination environmental documents and the construction and transfer of a water and sewer main line to be built by the developer. Plans for the project, at the intersection of Highway 49 and Parrotts Ferry Road, were approved by the Tuolumne County Board of Supervisors in 2017. A lawsuit was filed, and the developers were later victorious. The three commercial properties planned would use an estimated 1,084 gallons of water per day, according to TUD staff. This is the equivalent of four single-family homes. District staff determined in a report submitted that it would not have a notable impact on supply.
