Our Washington project teams recently completed a meticulous remediation project on a lakeside property at Lake Sammamish! Subsurface investigations revealed the release of heating oil into subsurface soil and groundwater from a former underground storage tank (UST), with contaminants found largely in the upland portion of the property.
This comprehensive environmental cleanup included residential demolition, remedial excavation and disposal of petroleum-contaminated soil, treatment and disposal of petroleum-contaminated groundwater, and site restoration to facilitate construction of a new residence beginning this month.
Our crews worked with archaeological monitors throughout the project to protect cultural resources while implementing erosion controls to safeguard the sensitive Lake Sammamish ecosystem. From demolition to site preparation for a new residential build, every phase prioritized environmental compliance and safety in this tight-knit community on the shore of Lake Sammamish. This project represents another step toward safer communities and cleaner waterways in the Pacific Northwest. Thank you to our ICS teams for their expertise and dedication!

We are proud to share that ICS project teams are back at the Santiago Basin in Orange County performing the Bond Basin Slope Repair Project for Orange County Water District (OCWD)!
Building on our successful completion of the Santiago Basin Intertie Repair in 2021, we are now addressing critical basin slope stabilization needs. Our current project involves comprehensive erosion repair along the southeast slope, including excavation and placement of over 10,000 cubic yards of engineered fill, abandonment of 50 linear feet of existing 60-inch storm drain, followed by installation of 270 linear feet of 60-inch storm drain infrastructure, and construction of new concrete swale and plunge pool systems.
ICS deeply values the trust OCWD continues to place in our team, affording us the opportunity to serve our Orange County communities once again!

We were thrilled to return to the WSPA tournament for the second time! This Monday, our NorCal team participated as a hole sponsor at the WSPA Associates Annual Championship Golf Tournament in Moraga, CA.
The Western States Petroleum Association (WSPA) is a non-profit trade association dedicated to ensuring communities have reliable access to petroleum and petroleum products through socially, economically, and environmentally responsible policies. This tournament`s proceeds benefited the Shared Energy Future Foundation (SEFF), which donated to food banks in Contra Costa and Solano counties.
Our NorCal team had a great time manning Hole 15, connecting with both new and familiar faces throughout the day. Our marshmallow golf competition was a hit and brought out plenty of smiles! It was a perfect mix of good food, great conversations, and genuine fun.
A big thank you to our friends at @officialwspa for coordinating such a well-organized and enjoyable tournament!🏌️♂️
