Our streambank restoration at a former nuclear weapons plant used bioengineered bank treatments to prevent erosion and protect the site, which is now a thriving wildlife preserve.

Our California Water Right Application and River Watershed Study included geophysical surveys and groundwater modeling; installing monitoring wells; water level/quality, river stage and hourly temperature monitoring; and obtaining permits from federal, state and local agencies.


Streams and rivers are vital for water supply, wildlife habitat, flood prevention, transportation, and recreation. Healthy stream and river systems constitute the lifeblood of watersheds. Apex provides stream restoration services to government agencies and private sector clients. Our multidisciplinary team of professional engineers, hydrologists, ecologists, geologists, archaeologists, and landscape architects addresses the unique issues presented by each stream and river with distinctive solutions.
