Preliminary Geotechnical Study at Nokomis Avenue Bridge Over San Anselmo Creek

The City of San Anselmo is conducting a preliminary geotechnical study at the Nokomis Avenue Bridge over San Anselmo Creek in Marin County. The primary objective of this project is to collect soil and groundwater data through geotechnical borings and subsurface investigations to support the development of engineering plans to repair scour damage at Pier 2 and Pier 3. These efforts are intended to protect the historical bridge from high-flow events and ensure the crossing remains safe for residents. The scope of work involves information collection and resource evaluation with minimal environmental impact. The project will not include any in-water work or the removal of healthy, mature, or scenic trees. Activities are limited to temporary, minor ground disturbance followed by immediate backfilling and restoration. Scott Schneider, the Public Works Director, serves as the primary point of contact for this effort, which is classified under NAICS code 541360.
