City of San Francisco Typical Plans and Specifications for Green Stormwater Infrastructure

Herrera worked closely with San Francisco Public Utilities to develop a comprehensive green infrastructure detail set with an eye toward stormwater management performance, constructability, maintainability, and compatibility with City requirements. The team developed a suite of standard details for permeable pavements, bioretention basins, bioretention curb bulbs, and bioretention planters for use in the dense urban right-of-way and on private parcels. We also expanded the detail set to include additional practices (e.g., biofiltration swales, drywells, interface with utilities/infrastructure) and monitoring details to allow accurate performance measurement.
