The vehicles driving in Anaverde Creek, a natural drainage channel/ephemeral stream, pose potential risks to water quality and surrounding ecosystems as vehicles can discharge oils, greases, and other chemicals into the waterway. Additionally, vehicles can disrupt the flow of water causing turbulent waters that result in erosion. All temporary and permanent impacts to a Water of the State require the filing of a report of waste discharge for a dredge or fill permit.
