Wildlife - Selected Project Experience

Miles Crossing Biological Assessment for Miles Crossing Sanitary Sewer District, Clatsop County, Oregon.
The Miles Crossing and Jeffers community is an unincorporated area south of Astoria, Oregon, which currently has no sewer service. Homes and businesses in the community use on-site treatment systems (septic tanks) for wastewater disposal. High groundwater levels in the community reduce the effectiveness of the on-site systems, and many of the systems are in marginal or failed condition. ES&A prepared USFWS and NOAA Fisheries Biological Assessments for the Miles Crossing Sanitary Sewer District project in Clatsop County, Oregon. Species evaluated included listed species (bald eagle, marbled murrelet, brown pelican, Columbian white-tailed deer, Oregon silverspot butterfly, water howellia, 5 ESU’s of steelhead, 1 ESU of sockeye salmon, 5 ESU’s of chinook salmon, 1 ESU of chum salmon, 3 ESU’s of coho salmon, coastal cutthroat trout). Also, per Rural Utilities District standards, 23 candidate species and species of concern were included in the impact evaluation.

Petaluma Water Resources Plan for City of Petaluma, Petaluma, California.
The City of Petaluma floods annually due to a combination of tidal influence from the San Francisco Bay and rainfall. ES&A performed a biological resources review for all significant waterways. Work involved both document and field reviews. ES&A documented sensitive, threatened and endangered species, and sensitive resources (i.e., wetlands) associated with the waterways. ES&A prepared a technical report summarizing findings, which will assist the project engineer in developing an approach to managing the City of Petaluma’s water resources. The document will also be used as a tool in public involvement, providing graphical information regarding Petaluma’s waterways and associated natural resources.

Rhone-Poulenc (RPAC) Site for AMEC Earth & Environment, Portland, Oregon.
Providing assessment of biological (wildlife) receptors that may be impacted by contaminants of concern at North Doane Lake, adjacent to the Rhone-Poulenc (RPAC) site in Portland, Oregon. Project work includes preparing a site assessment work plan, assessing for the presence of sensitive species (i.e., northern red-legged frogs and northwestern pond turtle), and evaluating the suitability of North Doane Lake habitat for other sensitive native bird, mammal and herptiles. Information will be utilized in the Level I and Screening Level II Ecological Risk Assessments for the RPAC site.
