Before construction, the Arizona crossing poses a major barrier to fish migration.
This photo is from the wet season; Carpinteria Creek dries out at this location in summer.
A few trees and shrubs were removed from the creek banks to allow access.
Disturbed soils will be restored with native plants at the end of the construction process.
An excavator with a "breaker" attachment begins to crack and remove the old concrete slab.
Several layers of concrete were discovered under the top slab.
Concrete and rebar remnants are excavated out of the channel
and hauled away for recycling.
Rock residue is used to fill the eroded gap downstream of the old slab.
The creek channel is re-graded to provide a consistent slope.
