Pi is a full service provider of dredge permitting and contaminated sediment support services. From the homeowner wanting to dredge their personal dock to the large agency looking for programmatic sediment management support, Pi’s unique combination of capability and flexibility enables effective solutions. Unlike other firms in southern California, we maintain a variety of internal equipment to support investigations and surveys that range from standard grain size analysis to full suite toxicological analysis. Our staff have leveraged their collective years of experience working on sediment projects and improved on the methods, accuracy, and costs associated with these types of projects regionally.
As a women-owned small business, Pi is equally comfortable as the project lead or as a trusted subcontractor. We routinely work with large engineering firms, local, state, and federal agencies, and private clients looking for consultation or support for their sediment related management concerns. If your project is in the CEQA/NEPA planning stage, has an existing NPDES permit, or you are looking to characterize potential dredged material for suitability and disposal alternatives analysis, Pi Environmental can help you accomplish your management goals and help make the technically complicated understandable.
