Chalk Mountain Road over North Fork Cache Creek Bridge
(Bridge No. 14C-0048) Replacement Project
NOTICE OF INTENT TO ADOPT A U.S. DEPARTMENT OF TRANSPORATION ACT SECTION 4(f) DE MINIMIS FINDING FOR IMPACTS TO HELEN MITCHAM PARK
WHAT’S BEING PLANNED
Lake County Department of Public Works proposes to replace the existing bridge on Chalk Mountain Road over North Fork Cache Creek (Bridge No. 14C-0048) located approximately 5 miles northeast of the Town of Clearlake Oaks in central Lake County. Below is a description of the proposed project.
The existing bridge was constructed in 1967, and is 206 feet long, 16.1 feet wide, and within the existing 40 feet wide public right-of-way. The bridge was classified as Structurally Deficient by Caltrans and needs to be replaced.
The new bridge would be constructed immediately downstream of the existing structure, in order to keep the existing road and bridge open to public traffic during construction. The replacement bridge would be approximately 220 feet long and wider than the existing bridge to comply with current AASHTO standards for local rural roads, which will include at a minimum two 9-foot travel lanes and two 3-foot shoulders, plus crash-tested vehicular barriers. It is anticipated that deep foundations would be needed to support the replacement bridge.
The Project will require permanent right of way take from the Helen Mitcham Park Day Use Area. The acquisition area is approximately 0.35 acres and is required to accommodate the construction of the new bridge. The permanently impacted portion of the Helen Mitcham Park will be reconstructed and will provide safer public access to the Helen Mitcham Park.
Construction is anticipated to commence in Spring 2020 or Spring 2021.
A Notice of Availability of de minimis Determination will be posted in the local newspaper, online at the County Website, and at the entrances to the Spring Valley Community Center.
WHY THIS NOTICE
The project is an action subject to the U.S. Department of Transportation Act of 1966 (49 U.S.C. 03 and 23 U.S.C.138 [PL 110-17], [PL 97-449], [PL 86-670]). Section 4(f) of this legislation seeks to protect publicly owned public parklands, recreation areas, waterfowl and wildlife refuges and significant historic sites from impacts – the “use” of these resources – by U.S. Department of Transportation actions. After an evaluation of the impacts of an action upon Section 4(f) resources, a finding must be made. The responsibility for Section 4(f) findings has been assigned by the U.S. Department of Transportation/Federal Highway Administration to the California Department of Transportation (Caltrans) under the Safe, Accountable, Flexible, Efficient Transportation Equity Act – A Legacy for Users (SAFETEA-LU) Act of 2005. Section 6009 of SAFETEA-LU allows determinations that certain uses of 4(f) land will have no adverse effect – de minimis – on the protected resource. Section 6009(a) requires that a public notice and opportunity for review and comment be provided for projects that are determined to have de minimis impact.
