Stewart shared pictures of the flooded property after floods in 2009 and 2016. “This is a hundred-year event … and I’ve been through two [of them],” he said. Stewart showed diagrams of drainage systems throughout Spanish Valley, indicating that a multiple—too many, he said—drained in the Rim Village area.
Stewart said that the culverts above Rim Village had the capacity to deliver 300 to 400 cubic feet per second of water into the area, while two 12-inch culverts that let water out of the area were insufficient for that level of flow. He suggested that installing larger culverts would impact adjacent property. “I don’t want to flood my neighbor,” he said. Instead, Stewart hoped the county would install culverts to divert water away from the subdivision and increase the number of retention ponds above Rim Village.
Council Vice Chair Curtis Wells thanked Stewart for the presentation and requested to have an item on the next county council agenda so that the council could discuss the issue with county staff.
