B Street Culvert Replacement

B St Culvert Repair Project Location

About

Project goals

  • Remove the existing concrete box culvert and replace with a new, partially cast-in-place and partially precast, concrete box culvert

Budget

Planning/Design $75,000
Construction $320,000

Overview

The project is located near the intersection of B Street and Woodland Avenue, 50 feet upstream of the San Rafael Creek.  Feeding into the upper reaches of San Rafael Creek is a reinforced concrete box culvert conveying water away from the Gerstle Park neighborhood. A small portion of the ceiling of the culvert requires rehabilitation to provide better structural stability of the system. In addition to the replacement of a section of the culvert, the City will coordinate with utility companies and regulatory environmental agencies. On August 31, 2020, the City hired the design consultant, Mark Thomas & Company, Inc., to prepare design plans for the project. Although City council awarded the construction contract to Maggiora & Ghilotti, Inc. on October 18, 2021, the project faced delays due to heavy storms that year. Subsequently, negotiations with the City concerning protection methods for the nearby PG&E pole led to further postponement. Eventually, increased material costs and scheduling conflicts prompted Maggiora & Ghilotti to request contract termination. On April 17, 2023, City Council authorized the termination. City staff rebid the project and returned to Council in Spring 2024 for consideration of a new construction contract. On April 15, 2024, City Council awarded the construction contract to Maggiora & Ghillotti, Inc. Construction is anticipated to begin in July 2024 and is expected to last for 3 months.
