DISCUSSION / BACKGROUND
This Project is necessary to repair damage to Airport Road caused by the storms of 2017. The Project consists of tree removal, slide debris removal including fallen trees, clearing and grubbing, culvert excavation, removal of an existing 18" corrugated metal pipe under Airport Road, installation of a new 18” reinforced concrete pipe, installation of underdrain system and permeable material, structure backfill, installation of rock slope protection, roadway excavation, installation of drainage inlet, installation of rolled erosion control product, placement of a new structural section, asphalt dike, asphalt paving for roadway and gutter, and striping work. The roadway will remain closed for the duration of this Project, with a detour in place.
Airport Road will be fully closed to traffic for twenty-nine (29) calendar days at Post Mile 0.31 (just east of the entrance to the airport). Access for local residents and visitors, as well as emergency personnel and law enforcement will be via detour to Airport Road, Broadway, Main Street, Cedar Ravine Road and Country Club Drive per the Detour Plan (Attachment C). Transportation has coordinated with local businesses, schools, and emergency services. Further notification will be given at least one week in advance of the closure once the construction schedule is known. Transportation will also notify the public of this road closure at least one week in advance via the County website, press release, and portable changeable message signs.
Due to federal funding, both California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) compliance are required. A CEQA Notice of Exemption was filed on May 18, 2017. A California Department of Transportation (Caltrans) NEPA Categorical Exclusion Determination was issued on June 26, 2017. All applicable environmental permits will be retroactively obtained for the Project as determined to be necessary and in conformance with Caltrans and FHWA emergency contract procedures.
