| Project Description: |
The purpose of marine sand mining is to obtain marine aggregate that is primarily used for construction activities within the greater San Francisco Bay area, either as fill and base material or as an ingredient in ready-mix concrete and hot mix asphalt. Sand obtained from the Bay-Delta estuary is used, for example, in the construction and maintenance of highway and freeway systems, commercial and public buildings, and residential construction. Marine sand is also used for local climate resiliency projects, i.e., beach and habitat restoration, and is used as a fill material for site remediation projects such as Hunters Points Naval Shipyard and Treasure Island. Marine sand mining is a critically important component of the scarce permitted sand reserves in the greater San Francisco Bay area. |
