CITY OF SANTA ANA CIVIC CENTER FACILITIES STRATEGIC PLAN WATER SUPPLY ASSESSMENT WATER SHORTAGE CONTINGENCY PLAN Within Section 5 of the UWMP, the water supply shortage policies Metropolitan and the City have in place to respond to events including catastrophic interruption and reduction in water supply are described. These include; Metropolitan Water Surplus and Drought Management Plan; Metropolitan Water Supply Allocation Plan; and City of Santa's Water Conservation Ordinance No. NS -2877. City of Santa Ana's Water Conservation Ordinance The City's Water Conservation Ordinance No. NS -2877 was passed by the City on May 19, 2015. The purpose of the Water Conservation Ordinance is to encourage reduced water consumption within the City through conservation, enable effective watersupply planning, assure reasonable and beneficial use of water, prevent waste of water, and maximize the efficient use of water within the City. It provides procedures, rules, and regulations for mandatory water conservation that gain results while minimizing the effect of a water shortage on the City's water customers. The City is fully dependent on Metropolitan and OCWD for its water supply. Confirmation of an extended water shortage emergency would generally be received from one or both of these agencies. An actual shortage does not have to exist; merely the threat of a shortage is sufficient cause to impose sanctions. When a water shortage appears imminent, the City Manager notifies the City Council and recommends holding a public hearing for the purpose of determining whether a water shortage emergency exists. If the City Council determines that a water shortage exists, it then makes the decision as to the appropriate phase of the Ordinance to implement. There are three Water Shortage Stages that the City can implement. A summary of the stages of water shortage is summarized in Section 5.2.3 of the UWMP. The City does not have a set percent supply reduction for each stage but will determine the percent reduction as it enters into each stage. Three -Year Minimum Water Supply As u matter of practice, Metropolitan does not provide annual estimates of the minimum supplies available to its member agencies. As such, Metropolitan member agencies must develop their own estimates. Section 135 of the Metropolitan Water District Act declares that a member agency has the right to invoke its "preferential right" to water, which grants each member agency a preferential right to purchase a percentage of Metropolitan's available supplies based on specified, cumulative financial contributions to Metropolitan. Each year, Metropolitan calculates and distributes each member agency's percentage of preferential rights. However, since Metropolitan's creation in 1927, no member agency has ever invoked these rights as a means of acquiring limited supplies from Metropolitan. As captured in its 2015 UWMP, Metropolitan believes that the water supply and demand management actions it is undertaking will increase its reliability throughout the 25-year period addressed in its plan. Thus for purposes of this estimate, it is assumed that Metropolitan will be able to maintain the identified supply amounts throughout the three -year period. Metropolitan projects reliability for full service demands through the year 2040. Additionally, through a variety of groundwater reliability programs conducted by OCWD and participated in by the City, local supplies are projected to be maintained at demand levels. 19 5ou1- -IJILb
