Environmental Services Unit

When County DPW requires environmental review, they turn to in-house experts in the Environmental Services Unit (ESU). Before DPW can begin construction, ESU conducts a thorough review to ensure the County complies with all federal, state, and local environmental regulations, including the California Environmental Quality Act (CEQA).

For more information about CEQA, please review this Fact Sheet.

ESU studies a wide range of resources, such as: biology, archaeological or historical resources, traffic, noise, and water quality to name a few.  

They review a variety of DPW facilities, including:

• Capital Improvement Projects
• Roads
• Airports
• Wastewater
• Flood Control

ESU also provides environmental guidance for other County departments. ESU is heavily involved in each project starting from its conception through construction and beyond.
