After precedent-breaking litigation, JMBM client, United Rock Products Corporation, and the city of Irwindale, California reached agreement to extend the life of the Irwindale quarries for 25 years. The transaction is most notable for the creation of a joint powers authority between the city of Irwindale and the Irwindale Reclamation Authority. Under the arrangement, the joint powers authority contributes millions of public dollars to a fund that is set aside for the eventual reclamation and development of United Rock’s quarries in the city. It is the first joint powers authority ever created in California for this purpose and resolved a major legal impediment to further mining for United Rock Products Corporation.
