The Water Conservation Landscaping Act (Assembly Bill 1881, Laird) has future repercussions for all California residents. This far-reaching act directs water providers and consumers in water use, and will dictate what kind of irrigation devices can be sold and purchased in California. The bill required cities and counties to adopt landscape water conservation ordinances by January 1, 2010. Any landscape one acre in size or greater may be subject to irrigation audits, irrigation surveys or water use analysis programs for evaluating irrigation system performance.
