Regional Stormwater Treatment Innovations: The Park Place Facility & POST Media Development Story


Video recording of the presentation.


This talk will tell the story of the planning, science, and design of the reconstruction of the City of Bellingham’s Park Place Stormwater Facility and the development of the novel POST media in partnership with WWU. The City of Bellingham & Whatcom County have spent several years working to improve water quality in Lake Whatcom by reducing phosphorus loading per the Lake Whatcom Watershed TMDL plan. In 2015 the City hired Herrera to prepare a design to reconstruct the Park Place Stormwater Facility which led to a R&D effort to develop a new high performance stormwater treatment media targeting phosphorus removal. Herrera partnered with the WWU College of the Environment on a lab bench scale and a field pilot scale study to develop and test the media. The full-scale facility reconstruction was constructed in spring 2022 and will go online treating run-off from 168 acres of the watershed in fall 2022.
