GSI City Details and Specifications
San Francisco, CA
Lotus is working closely with a leading team of consultants and the SFPUC Urban Watershed Management Program to develop typical plans and specifications for Green Stormwater Infrastructure (GSI) specific to the City and County of San Francisco. The typical plans and specifications will assist public and private sector design teams in developing construction level green infrastructure designs that meet regulatory standards. San Francisco’s two types of collection systems—combined and separate storm sewer systems—are taken into account in the typical plans and details, as well as the City’s varied physical and environmental conditions. This project aims to create a comprehensive and user-friendly manual that serves as a new national model for green infrastructure design in metropolitan areas.
