A 2"x6"X79" redwood board will be affixed to a concrete bridge pier of Highway 193, which is located in the South Fork American River. The wooden board will be attached to a concrete support pier which would be screwed to the wooden board. Work will occur during a period of low flows so that most of the installation will occur above the water. No ground disturbance will be required.
Minor alteration (affixing a staff plate) to an existing bridge for the purpose of gathering and providing information to the public about the stage of the river; therefore it is categorically exempt acording to Section 15301 and 15308 of the CEQA guidelines.
