This
project is being funded by the California Department of Fish and Game's Adaptive
Watershed Grant Program. Questa is providing professional environmental and
engineering services related to removal of a 9-foot-high concrete Arizona
Crossing and a golf cart bridge across the San Antonio Creek at the Soule Park
Golf Course. The Arizona Crossing, which was constructed at stream grade but
caused downstream bed scour, is currently precluding all fish passage (including
southern steelhead) upstream of the structure. The channel has completely filled
in with sediment behind the structure. The initial scope of work includes
geotechnical, hydraulic, and geomorphic analyses, and development of a
conceptual design. The overall objectives of the County are 1) to provide a
year-round, all-weather bridge to accommodate vehicles required for golf course
maintenance and 2) to facilitate the reestablishment of fish movement through
the project area. To accomplish these objectives, the pavement currently in the
channel bottom will be removed and a new bridge structure will be installed.
Bioengineering approaches will be utilized for bank stabilization. To date, a
conceptual design has been developed to enable the County to apply for grant
funding of the construction project. |
