We bring three decades of high-achieving water resources, environmental, and infrastructure expertise to public agencies and others across the country. We havebeen involved in some of the most iconic and groundbreaking water resources and environmental projects and challenges over the last several decades including:

Chicago Tunnel and Reservoir Project

CLIENT: Metropolitan Water Reclamation District of Greater Chicago (MWRD) (Illinois)

The $3.4 billion Tunnel and Reservoir Project in Chicago, which protects over 3 million homeowners and businesses from the ravages of flooding while safeguarding Chicago’s drinking water source, Lake Michigan, has been transformational. This stunning success story attracts international attention and has laid the foundation for a healthy and vibrant Chicagoland.

Hamilton Airfield Wetland Project

CLIENT: Coastal Conservancy (California)

Hamilton Airfield Wetland Projecttransforms a de-commissioned military airfield with legacy contaminants into a portion of the eventual 2,600 acre wetlands providing tremendous habitat and natural area in urban northern California. In fact, Hamilton is the largest wetland restoration project in the United States to beneficially reuse dredged sediment.

Mission Reach Ecosystem Restoration Project

CLIENT:San Antonio River Authority (Texas)

San Antonio’s Mission Reach Ecosystem Restoration Project, the natural extension of the River Walk, which restores 8 miles of the San Antonio River channelized by the Corps decades ago now creates a natural watercourse connecting the historic Spanish Missions to the waterway and providing a living river corridor and resource for families in an underserved community.

These are just a few of the major water resources and environmental successes we have been involved in over many years. We have represented cities, counties, water districts, conservancies, water reclamation districts, ports, flood control districts, urban and rural entities, river authorities, non-profit entities, state environmental agencies, as well as development districts and state departments of transportation to help them develop projects and secure federal funding.
