Blackburn Consulting provided investigation, design, and construction services for some of the most significant levee evaluations in Northern California:

These projects have included setback levees, seepage cutoff walls, seepage berms, seismic assessments, stabilization, erosion mitigation, condition assessments, and borrow site evaluations. We’ve cultivated valuable relationships with our local US Army Corps of Engineers, Department of Water Resources, Levee District, and Flood Control Agency contacts. We also work with the area’s premier civil levee designers and senior review consultants.
