RMC has been at its 3rd and Mariposa location for nearly 30years, but Catellus Development's plan for Mission Bay's mini-citydesign concept doesn't include heavy industry. It does include6,000 residential units, five million sf of commercial space andthe requisite public facilities, including a new University ofCalifornia campus and 45 acres of parks.

RMC has been searching for a new space, and has proposedbuilding a new plant at Pier 80. With the location's water access,the company could easily get the raw material needed for concrete.The site is ideal for the company, as it has rail access and isready for construction. Additionally, it is close to a lot ofconstruction, which is important for the concrete business, whichmust move the concrete quickly or it will perish.

However, residents and city officials have rallied against theproposed development, saying that the project doesn't fit into theneighborhood, and may hinder commercial development. In addition,they feel that there are potential health risks in operating aconcrete plant in the area.
