Integral staff have led award-winning projects involving the beneficial reuse of fill material. We have saved clients millions of dollars in eliminated soil disposal and construction fill costs, while realizing multiple benefits including dramatic reductions in roadway and infrastructure wear, fossil fuel use, noise and particulate emissions, and carbon footprint.
Integral engineers perform a wide array of in situ remediation projects including design, construction management, operations and maintenance, and project closeout. With skills in both in situ biological and chemical remediation approaches, we understand the benefit of these technologies as alternatives to energy and material-intensive aboveground systems, when appropriate.
Integral engineers bring sustainable stormwater management concepts to projects. We design natural drainage systems to reduce peak runoff rates and volumes and improve stormwater quality. Methods include bioretention, system landscaping, permeable pavement, and rain gardens. To improve water quality of runoff, we develop innovative, low cost passive-treatment methods that meet permitting discharge standards.
Integral uses analytical tools such as multi-criteria decision analysis to identify sustainable remediation, restoration, and redevelopment solutions. We have used this process in support of sustainable sediment management solutions in a multi-stakeholder environment, and for estuary restoration planning. Examples of criteria analyzed include project completion time, acres of habitat restored, jobs created, public acceptance, and cost.
Integral develops strategies to enhance ecological benefits at project sites. Our approaches have led to increased habitat for oysters in Coos Bay, Oregon, benthic recolonization and continued environmental improvement in Ward Cove, Alaska, and near-shore habitat restoration at Slip 4 in Seattle, Washington. We publish in peer-reviewed journals and are involved in ongoing research on habitat restoration.
