Examples of Our Work
PG&E Jefferson-Martin 230k-V Line Installation
The BioMaAS team conducted surveys for special-status species including the California red-legged frog and San Francisco garter snake on the Jefferson-Martin 230 k-V Line Project adjacent to the San Andreas Reservoir. Prior to construction, BioMaAS conducted protocol-level surveys along the project right-of-way, including a 90-day trapping survey for San Francisco garter snake, California red-legged frog, and western pond turtle. We provided detailed reports of our research, including GIS mapping. Team members monitored contractor compliance, reported on compliance to the client, and conducted all other aspects of permitted work required by resource agencies.

BioMaAS is currently conducting biological surveys and impact analysis for the construction and operation of turbines at the Shiloh Wind Farm in the Montezuma Hills Wind Resource area. We provide protocol western burrowing owl surveys and studies of avian mortality as part of a multi-year evaluation of mortality rates for newer generation turbines in order to assess the impact of these turbines on bird populations during the nesting season and during migration. Additionally, our team conducts prey monitoring, avian activity, and avian nesting surveys for the existing wind farm as well as for areas planned for future wind turbine installation. Data collected is...

Read MoreSan Francisquito Creek Emergency Pipeline Repair, Stanford, CA
BioMaAS provided environmental management and monitoring during an emergency pipeline repair requiring the dewatering of Central California Coast Steelhead habitat. Inspection of construction practices, monitoring water quality, relocation of biological resources, and coordination with city, county, state, and federal agencies, as well as the contractor, were top priorities on this high profile project. During post construction, BioMaAS prepared and implemented a revegetation plan for the site of emergency pipeline repair work on the bank of the San Francisquito Creek. This included the design and implementation of erosion control measures to stabilize the creek...

Prior to construction, BioMaAS conducted biological surveys and a trapping/relocation program for red-legged frogs along the tunnel corridor in coordination with nest dismantling for the San Francisco dusky-footed woodrat. Surveys for resident and migratory nesting birds occurred throughout the 4-year project. We presently coordinate environmental compliance efforts to satisfy all relevant agency permits for the three contract sites associated with the Devil’s Slide Tunnel Bypass Project. Issues of concern include wetland plants and special-status species such as California red-legged frog, San Francisco dusky-footed woodrat, migratory nesting birds, and...
Read MoreAlameda Creek and Eden Creek Biological Assessments, Alameda County, CA
BioMaAS conducted Biological Assessments (BA) for Alameda County Public Works and Sound Watershed. These BA’s included the Alameda Creek Desilting Project and the Den Creek Desilting Project in 2011. Our permitted biologists (for steelhead, salt marsh harvest mouse, and California red-legged frog) conducted reconnaissance surveys and database searches, as well as research and review of historical site data and previous reports concerning biological resources within the creek corridor for both Alameda Creek and Eden Creek. BioMaAS assessed the habitat for protected species and sensitive habitats, and coordinated with our team regarding jurisdictional wetland issues....
Read MoreAgua Caliente Biological Assessment and Wetland Delineation, Fremont, CA
BioMaAS conducted a delineation of waters and wetlands along Agua Caliente Creek channel to determine the jurisdictional limits of waters of the U.S. regulated by the U.S. Army Corps of Engineers under Section 404 of the Clean Water Act. The delineation was submitted to the Corps for verification. BioMaAS also wrote a biological assessment of the site which involved referencing the CNDDB, creating a vegetation cover map, conducting a rare plant and tree survey, and conducting habitat assessments for special status wildlife. The banks of the creek were severely eroded and restoration was planned for the site.

BioMaAS regulatory specialists conducted CEQA review for the slender false brome IPM plan and the associated public education plan for the Mid-Peninsula Open Space District. For this ongoing project BioMaAS is currently in the process of preparing a programmatic MND for this IPM. Tasks included review of all documents associated with the development of an extensive pest management and public outreach program designed to cover district lands in San Mateo County, development of mitigation measures in coordination with the resource agencies, and biological assessments at three District Open Space Preserves and adjacent lands. Environmental resources include wetlands and...
