More people, less water: this is the widely anticipated future of the state of California. As the state’s population grows to 46 million by the year 2020, California will strive to meet water demand with a reduced water supply from the Colorado River, and struggle with the devastating impacts to the Sierra Nevada snow pack caused by global warming. Yet isCalifornia preparingfor this future today? Does the law direct land-use planners on the city and county levels to work in concert with their water planning counterparts to prepare for these significant challenges? Asconcern over these issues has grown, recent judicial and legislative action has added new substantive requirements for land-use and water planning, as well as adding procedural requirements that ask land use and water planners to communicate with one another more consistently. In addition,both the Governor’s Office of Planning and Research (OPR) and the
California Department of Water Resources (DWR) are currently updating influential reference documents for land use and water planning professionals.
