Project Scientist

Mr. Yancey Cashell is an environmental scientist with 5 years of professional experience across the nonprofit, academic, and private sectors. He has worked as a California Environmental Quality Act (CEQA) practitioner supporting water infrastructure projects across southern California. He is proficient with the use of mapping applications, such as ArcGIS and QGIS, and with programming languages, such as R and MATLAB, which he uses to conduct quantitative analyses and support data visualizations.

Marine Science

Characterization of Shallow-Water Microbial Community, Santa Cruz de Tenerife, Canary Islands, Spain Spent 10 days aboard the R/V Ángeles Alvariño collecting samples to characterize the microbial community surrounding the hydrothermal vents of submarine volcano, Tagoro, in the Canary Islands. Oversaw the culture growth of more than 100 samples of bacteria, as well as the DNA extraction and 16S rRNA amplification process to conduct ecological analysis. Conducted bioinformatic pipeline and subsequent ecological analysis using R.
Ecological Health and Biodiversity Assessment, STARESO Marine Station, Corsica, France Conducted benthic resource surveys using the Posidonia oceanica Rapid Easy Index to determine the ecological status of a Posidonia oceanica meadow near the STARESO marine research station.

Planning and Permitting

Sonoma Baylands Mitigation Credit Agreement Application, Sonoma County, California Supported the preparation of a mitigation credit agreement for the California Department of Fish and Wildlife (CDFW) Regional Conservation Investment Strategies (RCIS) Program. Work included assessing potential for opportunities for advanced mitigation credits within RCIS framework for the Sonoma Creek Baylands Strategy. Work also required preparation of the application package and consultation with CDFW.
CEQA and Permitting for Various Sewer Rehabilitation Projects, Marin County, California Provided CEQA support and documents for Ross Valley Sanitary District on several infrastructure projects in Marin County. Developed initial study/mitigated negative declarations (IS/MNDs), CEQA addenda, and categorical exemption/notice of exemption documents for various sewer rehabilitation projects.
Piers 39–43½ Sediment Remediation Project, San Francisco, California Supported development of IS/MND addendum for CEQA review for remediation of PAH-contaminated sediments in the intertidal and subtidal areas near Pier 39–45 in San Francisco Bay.
Shell Pond Remediation Project, Contra Costa County, California Conducted biological monitoring for salt marsh harvest mouse (Reithrodontomys raviventris) during construction activities in compliance with authorizations from CDFW and U.S. Fish and Wildlife Service.
Copper Sulfate Application Project, Olancha, California Served as the deputy project manager to prepare a CEQA initial study/mitigated negative declaration for a project entailing the application of copper sulfate to treat harmful vascular plants along water conveyance and storage infrastructure.
Onyx Ranch South Fork Valley Water Project, Onyx, California Supported preparation of an environmental impact report under CEQA for a project involving the change in points of diversion for water rights along the Kern River to be used for irrigation and groundwater recharge.
Lake Perris Seepage Recovery Project, Perris, California Supported the preparation of an environmental impact report under CEQA involving the installation of recovery wells and conveyance pipeline to recover water lost to seepage from the Lake Perris Dam.
