Pier 70 Special Use District


Brookfield Properties


San Francisco, CA

Project Overview

The Pier 70 Special Use District consists of an approximately 35-acre area. Pier 70 is a site with a rich past with multiple buildings within in it designated as historical structures. The project incorporates this historical background with a new a vibrant neighbourhood for the City of San Francisco.   

The Project consists of a mixed-use land redevelopment program that includes residential, commercial office, retail, arts, light industrial and open-space uses. The Project will be developed in three phases. 

The major geotechnical constraints at the site include the existing underground fills, soft compressible soils, seismic lateral instability at the shoreline, rock excavations and naturally occurring asbestos (NOA). 

Engeo's Role

ENGEO provided geotechnical recommendations for the entire site redevelopment, including geotechnical and seismic engineering for the proposed residential and commercial buildingsWe provided geotechnical services for the seismic retrofit and lift for three existing, pre-WWII era structures. Foundation challenges included bay fill, soft and compressible bay muds, liquefiable material, and dipping bedrock. 

Challenges and Solutions

Some of the biggest challenges at the site included convincing public entities with jurisdiction on the project, that the site is being designed to perform well geotechnically and seismically. ENGEO overcame this challenge when we received approval by the Bay Conservation and Development Commission (BCDC) staff, without the need for a major review from their engineering criteria review board. ENGEO was able to answer the staff’s questions and comments clearly and was able to show the BCDC staff that the proposed geotechnical design of the site meets the objectives of BCDC.
