Herrera is thrilled to announce our collaboration with long-time client Seattle Public Utilities on the North Thornton Natural Drainage Systems Project. This project aims to reduce the amount of pollution in Thornton Creek and Lake Washington through the development of natural drainage systems (roadside bioretention), while also delivering community benefits such as reduced street flooding, added green space, new trees, and traffic calming.
Herrera is proud to bring a team comprised of small, local, women and minority owned firms, with Toole Design and Stepherson & Associates as key partners in this pursuit. Through this project, Herrera will lead options analysis, design, and construction support for approximately 25 blocks of natural drainage systems in the Lake City neighborhood. Our team looks forward to helping SPU deliver community-centered stormwater infrastructure that emphasizes equity and community benefits for all.
