Urban Coast fulfills the Center’s goal of providing a much- needed forum to highlight research that informs the most pressing issues of our day and policies that affect the condition of urban coastal resources. Urban Coast is a forum for researchers, agencies, advocacy groups, and other science and policy leaders to engage in constructive discussion and information exchange on issues that are pertinent to our coastal environments. In this way, we find common ground and highlight the robust science, analysis, and assessment needed to catalyze good policy, design, and management measures. The Center For Santa Monica Bay Studies The Center for Santa Monica Bay Studies is a program of the Seaver College of Science and Engineering at Loyola Marymount University and The Bay Foundation. The mission of the Center is to engage in multidisciplinary research on environmental and social issues affecting Santa Monica Bay and its watershed, and to contribute to policies and actions that improve the environmental condition of the Bay.

Los Angeles has been grappling with the problem of cleaning up work best and where, but we will need funding to make it happen. urban runoff for decades. The Clean Water Act is over 40 years old Relying on continued bond measures to build treatment facilities and requires that we meet water quality standards set by the state is not acceptable – bond funding can be used only for capital and federal Environmental Protection Agencies. Besides that, we projects, meaning there is no money available to pay for the ongoing are a region that understands the need for clean water in a very real operations and maintenance, and that just doesn’t work. In addition, way: too little water, or too dirty water, and our economy and quality most people agree that the best solutions are integrated solutions, i.e. of life decline, and fast. they solve more than one problem at once, so that stormwater can be captured, cleaned and stored for use by building a park or other As water management evolved in Los Angeles, we set up what could green space in a neighborhood that needs it. A dedicated funding be called a dis-integrated governance structure for water. We treat stream for stormwater cleanup could be crafted to require this kind drinking water, stormwater, and wastewater as if they are separate, of multi-benefit solution to our pressing water resource problems. unconnected resources or liabilities. We import drinking water from far away, then clean it very well and dump it into Santa Monica A property-based fee for stormwater is the fairest way to pay for Bay, at great expense. The tab is mostly picked up by the public, management of the resource. Property owners have the greatest who pay for drinking water as well as a monthly charge from their control over what happens to the water that falls on their land, and city or county for sewage treatment. At the same time, we direct could be rewarded with discounts or rebates for making simple, the rainwater that falls onto our streets and roof tops into storm on-site improvements that clean or infiltrate stormwater. Those drains and directly out to sea, laden with trash, oil, heavy metals and who choose not to improve will pay, and the funds can be used for other contaminants. This imposes another cost, when dirty water collective solutions like parks or underground treatment facilities and trash cause beach closures or discourage beach and ocean use. that will benefit everyone who lives in or visits the Los Angeles Now, we are under ever-greater pressure from the State Water region. What are we waiting for? Resources Control Board to clean up our stormwater. This is also a golden opportunity for us to do a better job of managing water overall: water is water, and LA needs to do a better job of stewarding rainwater as a valuable resource rather than a regulatory liability. The first step is to put in place a sustainable source of funding for managing our local water. We know a lot about how to do it, and Shelley L. Luce, Executive Director we can answer outstanding questions about which technologies The Bay Foundation PHOTO: LARRY BRAMBLES URBAN COAST 4 | 1 December 2013 1 URBAN COAST VOLUME 4, NUMBER 1 Editorial StaFF Editor’s Note Dr.
