Redwood Cabin Removal Project
The Midpeninsula Regional Open Space District (Midpen) proposes to demolish the Redwood Cabin and remove associated features onsite, including the stone retaining walls and barbeque and fire pits. Prior to demolition activities, lead-based paint present within the structure would be properly removed and disposed of. While it is expected that excavation of posts and bases associated with the structure would be approximately 2 feet below grade, it is possible that maximum depth of excavation could reach up to 5 feet. During demolition of the structure, it is estimated that approximately 60 tons of material would be removed from the project site. Tree removal will not be required to facilitate demolition activities, although some brush clearing along the access road may be necessary. Following completion of demolition activities, disturbed areas would be recontoured and erosion control applied to the site to ensure adequate site drainage. All demolition and recontoured areas would be compacted to 75 percent relative compaction. Native grass seed mix would be spread in the disturbed areas and weed free or native grass straw would be placed in the disturbed areas, on top of the native grass seed mix, to assist with soil stabilization and erosion control. Any wood chips or mulch generated from unsalvageable building materials may also be used to stabilize disturbed areas but will not be more than 3 inches in depth. Midpen also conducts early detection rapid response surveys for up to 3 years at revegetation sites and treats any invasive plant species on the early detection rapid response list. Other priority integrated pest management target species, including slender false brome may be treated prior to and after demolition. Slender false brome is an invasive weed of high concern at the project site; due to Midpen’s mandatory quarantine of this weed, all slender false brome in the area will be treated prior to any work being completed. Current activity at the project site consists of occasional visits from Midpen staff for inspections. Once removal of the structure and site recontouring/erosion control activities are complete, no additional maintenance or operational activities would be required at the project site except for invasive plant species treatment, if needed. The site would remain closed to the public.
