Herrera is testing to see whether new soil mixes can remove
more heavy metals and other pollutants from stormwater.
With all the cranes towering overhead in downtown Seattle, it’s easy to forget the important work going on below to manage and protect our water as the region grows.
To keep pace with this growth, Washington State is pioneering the use of new and innovative approaches for stormwater management. As of next year all development projects must use low impact development (LID) techniques or green stormwater infrastructure where feasible. Rain gardens, bioswales, green roofs, and permeable pavement will become the norm rather than the exception.
As the region makes this new investment to protect our water, everyone – regulators, project owners, designers, and the general public included – will want to be confident these technologies are providing the intended benefit.
Herrera Environmental Consultants, Inc. is conducting groundbreaking research to assess and optimize the performance of these systems.
For example, with grant funding from the Washington State Department of Ecology, Herrera is currently implementing two research projects to develop a more effective soil media for use in bioretention systems.
In partnership with Kitsap County, one of these projects has involved numerous pilot scale tests of soil media components and blends to optimize their removal of heavy metals and other harmful pollutants from stormwater.
Herrera has also partnered with the City of Redmond to construct a state-of-the-art research facility for evaluating pollutant removal and plant growth in bioretention systems at full-scale.
Herrera Environmental Consultants, Inc. is an employee-owned engineering and scientific firm focused on restoration, water, and sustainable development. Herrera is committed to working with our clients to develop innovative and sustainable solutions for infrastructure, natural resources, and stormwater projects.
