1. Biological Services
Chambers Group Biological Services staff possesses a tremendous
depth of experience in terrestrial/aquatic wildlife and plant ecology
that is mobilized to conduct biological assessments, habitat evaluations
and presence/absence surveys for sensitive plant and wildlife
resources. The staff regularly consults with regulatory agencies under
the federal and state Endangered Species Acts and provides biological
technical reports in support of EIR/EIS documents in compliance with CEQA/NEPA. Chambers
Group biologists also assist clients with the design and implementation of mitigation bank
programs and natural resource management plans.
The Biological staff has won awards for its responsiveness and its goal is to add value to
every project. The staff likes to work closely with the client project team, engineers, and
designers to identify opportunities to minimize project impacts and, therefore, mitigation
costs. This interaction includes creative contingencies to avoid cost overruns while keeping
the project on schedule.
Project experience includes work in both urban and rural environments in coastal areas,
wetlands, rivers, streambeds, flood plains, deserts, reservoirs, parks, and landfills in support of
projects such as long distance fiber optic cable installations, additional railroad lines, new
transmission lines, solar energy sites, sediment removal projects, bridges, pipelines, and
transportation improvements.
Chambers Group offers services and capabilities in all phases of
biological sciences and its multidisciplinary teams address each
client’s unique needs and each resource’s distinct significance.
