Sustainable Engineering

Integral scientists and engineers provide clients with technical assessments, strategic advice, and management tools to reduce the environmental risk footprint of engineering projects while enhancing performance and value. When our clients demand sustainable approaches, our staff collaboratively design and implement them. For example, our engineers have worked with state regulators to create policy opportunities for sustainable reuse of fill material and then designed and implemented these approaches. Our credentialed engineers plan and design low-impact development design strategies, such as sustainable stormwater infrastructure, for remediation sites and redevelopment projects.

We also have proven expertise in design and implementation of in situ remediation technologies under a variety of site conditions to significantly reduce the carbon footprint and materials usage of remediation systems. We combine our engineering and ecological expertise to enhance habitat and provide ecological end use benefits at project sites.

Beneficial ReuseBeneficial Reuse

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.

Green Remediation“Green” Remediation

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.

Stormwater ManagementStormwater Management

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.

Decision AnalysisDecision Analysis

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.

Habitat EnhancementHabitat Enhancement

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.
