Stream-Related Construction and Road Repair Projects
From 2005 to the present, DWA has provided the fisheries portion of biological assessments for Federal
Biological Opinions related to various Santa Cruz County Public Works projects. These projects have
included numerous bridge replacements, bridge retro-fittings and stream-side road repairs with erosive
slip outs, giving Mr. Alley considerable experience in working with construction contractors. For
example, in 2005 Mr. Alley provided the fishery analysis for replacement of the Olson Road ford with a
free-span bridge on West Branch Soquel Creek, satisfying CEQA and federal Biological Opinion
requirements.
During project implementation, DWA has captured and relocated steelhead, tidewater gobies, California
red-legged frogs and other aquatic species from project sites with electrofishing and seining. Alley has
supervised cofferdam construction, monitored construction and completed monitoring reports to satisfy
regulatory requirements for more than 30 stream-related construction projects where federally and state
listed species were at issue. Projects have been located from Santa Cruz County east to San Benito
County and south to San Luis Obispo County, with clients including county and city public works
departments, RCD’s, water districts and private land owners.
