The City's 1990-2005 General Plan/Local Coastal Plan previously required a minimum 100-foot setback from new development to the centerline of all watercourses unless a management plan was prepared. The City Council and Coastal Commission requested that staff prepare a management plan for watercourses city-wide to modify this setback requirement to reflect variations in the values of watercourses in the City. The City Council adopted the Plan and Ordinance on February 28, 2006. The Plan was Certified by the California Coastal Commission on May 9, 2008. The Plan provides specific setbacks for each watercourse and a series of aerial maps delineating these setback requirements.
