The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement number 1600-2019-0240-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, California Department of Transportation. The project is part of a larger project to construct and/or upgrade existing curb ramps and sidewalks along State Route 88. Project activities include the construction of temporary forms to contain demolition debris or concrete pours where the existing sidewalk near the abutment overhands the steep northwestern streambank and streambed area below. Work includes the installation of temporary scaffolding, temporary cantilever brackets or other appropriate falsework to support the proposed concrete formwork and or concrete demolition containment systems
from below. The falsework system will be founded on the streambank slopes and will consist of mudsills (sections of lumber or metal plates) or other adequate firm foundation set onto two 4-foot wide hand excavated benches on the slope. The proposed project will result in approximately 235.34 square feet of temporary impacts to areas consisting of bed, bank, and channel habitat within the North Fork of Jackson Creek. The temporary disturbance area is expected to result in the trimming or removal of approximately one tree of heaven and stream bank vegetation dominated by Himalaya blackberry, everlasting pea, and white sweet clover.
