SR 06-27-2017 3B Ci ty Council Report City Council Meeting : June 27, 2017 Agenda Item: 3.B 1 of 7 To: Mayor and City Council From: Susan Cline, Director , Public Works, Office of Sustainability & the Environment Subject: Update to the Water Shortage Response Plan Recommended Action Staff re commends that the City Council a dopt the Water Shortage Respo nse Plan resolution (Attachment A). Executive Summary The City has in place a Water Shortage Response Plan (WSRP ) that requires water customers to meet a water use allowance (Allowance) whenever a Stage 1, 2, 3, or 4 w ater s upply s hortage is declared by C ity Council. Currently, the City is in a dec lared Stage 2 w ater s upply s hortage with allowances set a t 2 0% below a customer’s 2013 water consumption. In January 2017, the 2016 California Green Building Standards went into effect lowering flow rates for ne w and/or retrofitted faucets and urinals. In addition, on May 23 , 2017 Council adopted the water neutrality ordinance that requires a new development to consume no more water than the prior use . As a result, the new development is required to calculate the new water demand. Staff is recommending an update to the WSRP (Attachment B ) that would establish the new development’s approved new water demand as the Allowance during a declared water supply shortage and change the plumbing fixture flow rates to match the current State Building Code requirements. Background Between 2007 and early 2017, with the exception of 2011 -12, California was in a record drought. The drought resulted in the lowest rainfall and snowpack since 1896. On May 27, 2008 , Council adopte d amendments to SMMC 7.16 - Water Conservation, which gave Council the authority to determine and declare a water supply shortage and to adopt a WSRP (Attachment C ). The WSRP was developed in 2009 to comply with the 2 of 7 State’s Urban Water Management Plan requ irements and was based on the California Department of Water Resources 2007 Urban Drought Guidebook. On June 9, 2009, Council adopted the WSRP (Attachment D ). The WSRP was included in the City’s 2010 Urban Water Management Plan, which was subsequently ap proved by the State. The WSRP mandates that when Stage 1, 2, 3, or 4 water supply shortage is declared, A llowances go into effect. This mandatory conservation requires water customers to reduce use by a set percentage from a prior year’s water usage. T he C ity is currently in a Stage 2 w ater s upply s hortage and A llowances are in effect that are 2 0% below the customer’s 2013 water usage . Water customers that exceed their A llowance are subject to fines and civil penalties. Adjustments to the A llowance may be g ranted if certain criteria including water -saving plumbing fixtures are installed. Also on June 9, 2009 , Council declared a Water Shortage Advisory calling for a voluntary 10 % reduction in water u se in response to the drought. The Water Shortage Advisory remained in place as part of the effort to reduce the need to import water from MWD and reach the City’s goal for water self -sufficiency by 2020. In response to the continuing drought, o n January 29, 2014, the City increased its voluntary conservation targ et from 10% to 20% (Attachment E ). On August 12, 2014 , Council adopted a resolution , per Attachment F , declaring a Stage 2 Water Supply Shortage , which changed the voluntary 20% conservation target to a mandatory 20% reduction in water use . It also dir ected staff to return with a detailed Stage 2 Water Supply Shortage implementation plan including proposed amendments to Section 7.16 of the Municipal Code and the WSRP, a financial impact analysis to address revenue reductions , additional staffing and pro gram implementation costs, and an implementation timeline. On October 28, 2014 , staff returned to Council and presented proposed updates to the WSRP (Attachment G ) as well as information about proposed changes to the Municipal Code and implementation of w ater shortage response measures. Council provided feedback and directed staff to return with proposed changes to the WSRP that included 3 of 7 input from the public, a Water Conservation Unit within the Office of Sustainability and the Environment to implement t he Stage 2 Water Supply Shortage, and return with proposed changes to the Municipal Code that related to water conservation. On January 13, 2015, Council re -affirmed and re -declared a Stage 2 Water Supply Shortage and adopted updates to the WSRP (Attachm ent H ). This included Allowances for all water customers set at 80% of their 2013 water usage for Stage 2; established penalties for exceedance of Allowances ; established residential water conservation thresholds for single family and multi -family resident ial customers; and provided a process for adjustment of a n Allowance. On September 8, 2015, Council adopted an update to the W SRP (Attachment I ). The major updates were to modify the penalty fee structure for exceeding the A llowance and to provide for wa iving of the first exceedance penalty by participating in a City -offered water school. On January 1, 2017, the current California Green Building Standards went into effect in Santa Monica lowering the flow rates for plumbing fixtures including urinals and faucets. The WSRP includes specific flow rates for plumbing fixtures that must be installed in order to receive a water use allowance adjustment. On May 23 , 2017, Council adopted the water neutrality ordinance (Attachment J) that requires new development s to use no more water than the current usage. As a result, a developer is required to calculate the projected water demand for their proposed new development . Discussion The WSRP is a roadmap developed in response to impending and ongoing water supply sh ortages. It is updated at least every five years as part of the State required Urban Water Management Plan. There are five stages (Advisory and Stage 1 to 4) of water supply shortages within the WSRP and actions range from voluntary to mandatory water cons ervation. The mandatory conservation requirements are 4 of 7 implemented through Allowances assigned to water customers. Water customers are required to reduce their usage by a set percentage depending on the current stage of water supply shortage. Water Use All owances for Residential, Commercial and Landscape Water Customers (excluding Santa Monica Urban Runoff Recycling Facility customers) In response to the unprecedented drought and its ongoing effects on Santa Monica’s water supply, the City remains in a Stage 2 Water Supply Shortage that requires a 20% reduction in water use from 2013 levels . Local groundwater provides about 75% of the City’s water supply, which has yet to recover fully, even with the recent record -breaking rains . T he natural process by which this occurs takes time and it may be a few years, along with more wet winters, for local groundwater suppl ies to return to pre -drought conditions. In order to be at least as effective as the current California Green Building Standards, the WSRP must be updated to reflect new requirements for plumbing fixture flow rates. This includes lower flows for urinals and faucets. As part of the recently adopted water neutrali ty ordinance, developers are required to calculate the projected water demand for a new development project. For the purpose of the water neutrality ordinance, n ew developments are defined as : new buildings with plumbing fixtures; existing buildings with p lumbing fixtures where 50% or more of the exterior walls or major support structures are demolished; and /or new or enlarged pools, spas, water features, and ponds. If the calculated water demand from the proposed new development is greater than the amount the property currently uses (using a five -year average), then the developer must attempt to design a more water -efficient property through fixtures and systems (e.g. graywater and rain water harvesting). If the new Stage 1 Stage 2 Stage 3 Stage 4 % Water Available per Customer 85% 80% 70% 50% 5 of 7 development is still projected to use mor e water after all practical water -saving devices and systems are included in the design, then an in -lieu fee is required. Those fees pay to retrofit existing off -site buildings with water -saving fixtures to offset the additional water demand of the new dev elopment . Once approved , the calculated water demand for the new development would be used as the Allowance for the property during a declared water supply shortage provid ing a realistic yet water -conserving target . Currently, Allowances are a 20% reducti on from usage in 2013. N ew developments that calculate greater water use than the current property’s five -year average would not likely meet Allowances as defined and , subsequently, could be fined for exceedances . This would trigger requests for adjustment s to their A llowance s. These adjustment requests would be granted because the development s would be built to the current water -efficient building requirements , which i s a pre -requisite for an adjustment. Setting the new development’s Allowance as the cal culated and approved water demand provides the most accurate water budget and would lead to fewer exceedance citations issued and fewer adjustment requests. Requiring the Allowance to equal the approved new water demand will encourage designer(s) of new de velopments to produce accurate estimations to help their clients avoid A llowance exceedance penalties. The Allowance would be updated after the certificate of occupancy or temporary certificate of occupancy is issued. This proposed update to the Allowance would not apply to new or enlarged pools, spas, water features, and ponds. Outreach Five Water Neutrality Stakeholder Committee meetings were held on November 15, 2016, December 12, 2016, January 24, 2016, March 8, 2017, and April 4, 2017, where proposed requirements of the ordinance and its implementation were discussed and a consensus on recommendations was achieved . Stakeholder Committee members include representatives from water agencies, non -governmental organizations, sustainability consultants, arc hitects, developers, manufacturers, engineers, plumbers, Los Angeles County; the City’s Water Advisory Committee , including residents ; and 6 of 7 staff from the Public Works Department, Planning and Community Development Department, and the City Attorney’s Office . Staff also presented this information to the Chamber of Commerce Governmental Affairs Committee on March 6, 2017. A public meeting was held on April 6, 2017 and 10 community members attended. A presentation was made to the North of Montana Association (NOMA ) neighborhood association on April 6, 2017 and at the Mid -Cities neighborhood association on April 18, 2017 . The public was notified by emails sent to all the neighborhood groups and business districts; Facebook postings, a press release, and calenda r event listed on the City’s website. Information about the ordinance and how to comply with it will be posted on the City’s website. The proper notices were included in the Santa Monica Daily press and made available in the City Clerk’s Office in accordan ce with noticing requirements. Water Advisory Committee Presentation took place on February 6, 2017 and the recommendation was in support of the ordinance. Task Force on the Environment Presentation took place on March 20, 2017 and the motion was made in support of the ordinance. Alternatives The current process for Allowances would remain in place if this update is not approved. New developments would be required to reduce 20% from the 2013 water usage or default baseline or comply with a threshold if i t is a single -family or multi -family customer. Financial Impacts and Budget Actions There is no immediate financial impact or budget action necessary because of the recommended action. 7 of 7 Prepared By: Kimberly O'Cain, Senior Sustainability Analyst Approved Forwarded to Council Attachments: A.

The WSRP is intended both as an action plan and as the implementing regulations for water conservation as authorized by Section 7.16.030. It is designe d to reduce water demand during water shortages. The WSRP is based in part on the State of California Department of Water Resources 2007 Urban Drought Guidebook . The Urban Water Management Planning Act (Section 10632 of the California Water Code) requires water shortage contingency planning as a component of the Urban Water Management Plan, which is updated every five years. The WS R P establishes five stages of water shortage severity based on predicted or actual water supply reductions. Each stage establishes water use reductions through voluntary or mandatory measures. Triggers for implementing the WSRP may include such events as a state or local emergency; n atural disaster ; a localized event that critically impacts the water supply ; drought or t he City’s wholesale water agency imposing water allocation restrictions . Section 2 : Objectives and Priorities of Water Use A. The o bjectives of the WSRP are to : (1) Prioritize essential uses of available water; (2) Avoid irretrievable loss of natural resources; (3) Manage current water supplies to meet ongoing and future needs; (4) Maximize local municipal water supplies ; (5 ) Eliminate water waste city -wide; (6 ) Create equitable demand reduction targets; and (7 ) Min imize adverse financial effects . B. The following priorities for use of available water are listed in order from highest to lowest priority: (1) Health and Safety including: consumption and sanitation for all water users; fire s uppression; hospitals, eme rgency care, nursing and other convalescent homes and other similar health care facilities; shelters and water t reatment; (2) Institutions, including government facilities and schools such as public safety facilities, essential government operations, publi c pools and recreation areas; (3) All non -essential commercial , institutional, and residential water uses; (4 ) New water demand. Section 3 : Triggers for Implementation The City Council may declare by resolution that an Advisory or Stage 1, 2, 3 or 4 Water Supply Shortage exists and that the actions outlined in this WSRP are necessary. Upon Council adoption by resolution, any Advisory or Stage may be rescinded. The type of event which may prompt the City Council to declare a n Advisory or Stage1, 2, 3, 4 Wat er Supply Shortage may include, among other factors : City of Santa Monica Water Shortage Response Plan –June 2 7 , 2017 Page 4 of 12  D rought ;  S tate or local emergency ;  A natural disaster that critically impacts the water treatment or water distribution system ;  A localized event that critically impacts the water supply, water quality, water treatment or water distribution system ;  T he City’s wholesale water agency requests extraordinary water conservation efforts in order to avoid mandatory water allocations ;  T he C ity’s wholesale water agency implements a water allocation. Section 4 : Stages of Water Shortage Supply The WSRP establishes five stages of severity based on predicted or actual water supply reductions. Each stage establishes water use reductions either through voluntary or mandatory measures. Mandatory water restrictions include water use allowance for each water customer category. Table 1 below outlines the stages and water use reduction goals. Table 1 : Water Shortage Re duction Targets Section 5 : Water Use Restrictions for All Stages The water conservation requirements in SMMC Section 7.16 are permanently enforced . Section 6 : City of Santa Monica Staff Responsibilities (A ) City staff will be informed of the water supply shortage. Each staff member will be expected to use water efficiently. (B ) T he City’s landscaped areas will be efficiently irrigated based on the Irrigation Association’s Best Management Practices. (C ) Each staff member will be expected to notify the appropriate City department immediately of any leaks seen on City property or private property . Section 7 : Water Allowances for Stages 1 , 2, 3, 4 A Water Use Allowance (WUA) is established for each water customer. The WUA shall not apply to: Water Shortage Stage Water Use Restrictions City -wide Use Reduction Goal Advisory Voluntary 10% Stage 1 Mandatory 15 % Stage 2 Mandatory 20% Stage 3 Mandatory 30% Stage 4 Mandatory 50% City of Santa Monica Water Shortage Response Plan –June 2 7 , 2017 Page 5 of 12 (A ) Any water customer of the City of Santa Monica during a n Advisory wat er supply shortage stage; (B ) Any water customer account designated for municipal non -potable water. Summary of Allowances A WUA is the maximum allowable amount of water that could be used by a water customer and it is calculated as a percent reduction in the amount of water available for each water customer in the City of Santa Monica for the duration of a declared water shortage. The WUA is calculated as a percentage of the baseline year’s water usage. The baseline is calendar year 2013. Each water customer will receive a WUA for each billing period. A billing period is approximately 60 -days. Public agency , including but not limited to the City of Santa Monica, Caltrans, Santa Monica -Malibu Unified School District, individual landscape only accounts will be combined and receive one WUA . Water Use Allowances for new water accounts , new water customers, properties vacant in 2013 , and water accounts with zero usage in 2013 will be based on the average usage of water customers in the same water customer class (single -family, multi -family, mixed -use, commercial, industrial, landscape, etc.) with the same meter size. For example a single -family water customer whose home was vacant due to a remodel in 2013 and as a result of the remodel their meter size increased from ¾ inch to two inch because the house size increased significantly, shall get a WUA that is the average of oth er single -family homes with a two inch meter. Water Use Allowance s The Water Use Allowance formula for residential water customers is: The average daily baseline use per billing period x the % of water available or the residential threshold ; whic hever is higher The Water Use Allowance formula for commercial and landscape water customers is: The average daily baseline use per billing period x the % of water available City of Santa Monica Water Shortage Response Plan –June 2 7 , 2017 Page 6 of 12 The Water Use Allowance for new developments shall be the approved new water demand as defined by SMMC 7.16.050 . This does not apply to new or enlarged pools, spas, ponds or water features.

Water Shortage Supply Stage 3 & 4 Penalt ies will not be imposed for single family customers using less than 16 HCF per bi - monthly billing period and each multi -family unit per building using l ess than 8 HCF per bi -monthly billing period . City of Santa Monica Water Shortage Response Plan –June 2 7 , 2017 Page 7 of 12 Section 8 : Pena lt ies When a Responsible Party exceed s the applicable WUA during a billing period , a Penalty may be imposed through the issuance of a n administrative citation . The citation fine amount will be calculated as set forth below.  first violation penalty: $250  second violation penalty (within twelve months of the first violation): $500  third violation penalty (within twelve months of the second violation): $1,000 Any Responsible party that exceed the WUA three times may be required to have a water audit performed by a licensed engineering firm having water audit experience and all related expenses paid by the Responsible Party . The audit must be performed and a full report submitted to the City of Santa Monica within 30 -days of notice. The audit report must include how the audit was administered, list all interior and exterior uses of domestic and non -domestic water uses, results of the audit, recommendations, and return on investment ca lculations. The City may require the implementation of the audit recommendations as a precondition to granting any request for a WUA A djustment. Any Responsible Party that exceed the WUA seven or more times may have a flow restrictor installed in the meter which restricts the flow of water going into the building, be charged with a C ivil P enalty, and/or be charged with a criminal penalty. Section 9: Waiver of Penalty Any Responsible Par ty that receive s a first violation WUA exceedance penalty may choose to attend a City offered water school . Upon successful completion of the water school, the penalties associated with the first violation shall be waive d . The City Manager or his or her de signee is authorized to develop regulations to implement the water school program consistent with the policies, objectives and priorities of this Plan . Section 10 : Water Use Allowance Adjustment Application for Water Use Allowance Adjustment  Comply with requirements listed under Required Finding for a n Adjustment.  Fill out a Water Use Allowance Adjustment A pplication available at 1717 4th St., Su ite 150, Santa Monica, CA 90401.  Submit completed application and required supporting documentation (such as photographs, itemized receipts, maps, drawings, engineering reports, water audit reports, utility bill showing participation in any low income assistance program, or other pertinent information) by mail or in -person at 1717 4 th St., S uite 150, Sa nta Monica, CA 90401. Approval Authority The Adjustment Administrator will exercise approval authority and act upon any completed Water Use Allowance Adjustment Application after submittal and may City of Santa Monica Water Shortage Response Plan –June 2 7 , 2017 Page 8 of 12 approve, conditionally approve, or deny the adjustment req uest . The applicant requesting the adjustment will be notified in writing of any action taken. The decision of the Adjustment Administrator shall be issued within sixty days after the conclusion of the hearing or the submission of all written materials if no hearing is conducted. The applicant may appeal any such decision pursuant to Chapter 6.16 of this C ode . Unless specified otherwise at the time the adjustment is approved, the adjustment applies to the subject property during the term of the applicable stage of the WSRP. Factors to be considered by the Approval Authority in Reviewing a Water Use Allowance Adjustment Application :  Whether denial of the application would create an undue hardship which could create an emergency condition relating to health or safety ; or  Whether an undue financial hardship to a water customer would result ; or  A new water account is requested by a new user; or  T he property was vacant (or otherwise devoid of water use) during 2013 but is now being inhabited; or  T here has been an increase in household size or change in tenancy Required Findings for an Adjustment An application for an adjustment will be denied unless the approving authority finds, based on the information provided in the application, supporting documentation, and/or such additional information as may be requested, and on water use information for the property as shown by the records of the City of Santa Monica, all the following: 1. The subject property has implemented all practical water saving measures at minimu m , unless unique circumstances that makes meeting these requirements impossible : a. High -efficiency toilets (uses 1.28 gallons per flush or less) b. High -efficiency urinals (uses 0.125 gallons or less per flush or is waterless) c. High -efficiency showerheads (uses 2.0 gallons per minute or less) d. High -efficiency faucets (uses 1.2 gallons per minute or less for residential or guest rooms; uses 1.8 gallons per minute or less for kitchen faucets; uses 0.5 gallons per minute or less for commercial) e. No leaks anywhe re on the property f. No irrigation runoff and overspray 2. That the adjustment does not constitute a grant of special privilege inconsistent with the limitations placed upon other City of Santa Monica water customers. 3. That because of special circumstances applicable to the property or its use, the requirements of the Water Shortage Response Plan would have a disproportionate impact on the property or use that exceeds the impacts to customers generally. 4. That the adjustment will not materially affect the abil ity of the City of Santa Monica to effectuate the purpose of the Water Shortage Response Plan and will not be detrimental to the public interest.

Background On February 26, 1991 , Council adopted an emergency ordinance to establish Santa Monica Mun icipal Code Chapter 7.16 implementing mandatory water conservation measures due to drought. On June 10, 2008 , Council adopted modifications to Ordinance 7.16.0 3 0 to update and amend water conservation requirements. On June 9, 2009 , Council adopted the Water Shorta ge Response Plan and declared an advisory - level water supply shortage in response to statewide drought conditions in mid -2008. On September 13 , 2011 , Council adopted a resolution to continue the water shortage advisory as local groundwater supplies d id not meet the city’s total water demand. Discussion The Water Shortage Advisory is still in effect and calls for a voluntary 10% reduction in water use . With 201 3 being the driest year in recorded history and the second drought in five years to be declared by the Governor, it is imperative that Santa Monica use its water supplies efficiently. The Governor’s call for a 20% reduction in water use as a response to the drought dovetails with the City’s goal of reducing current water demand to achieve water self - sufficiency by 2020. Due to the drought , the voluntary reductions need to begin 2 immediately to reduce water usage and avoid mandatory water restrictions late r this year. Water self -sufficiency means eliminating the City’s reliance on imported water, using limited local groundwater wisely and efficiently, and optimally managing the local water supply. It also means having adequate water supplies regardless of t he weather conditions . Staff is asking residents and businesses to voluntarily cut water use by 20% from their average water use in 2013 immediately in order to become water self -sufficient and avoid a drought -induced water crisis and mandatory water rest rictions. Currently , the City maintains the capability of producing more than 70% of its water needs from local groundwater, with the remainder imported and purchased from the Metropolitan Water District of Southern California (MWD). MWD receives the maj ority of its supplies from Northern California and the Colorado River, both of which have been significantly impacted by drought. While MWD expects to meet water demands in 2014 because of its significant investments in water storage, water transfers, and conservation in preparation for dry years, it is encouraging customers to use water wisely and efficiently . C ities like Santa Monica are being asked to develop additional local water supplies. Santa Monica’s local groundwater can be seri ously impacted b y drought. Each day water is extracted from groundwater wells to meet the water needs of the community. When it does not rain, groundwater replenishment is diminished. To ensure sufficient supply for the future, it is critical to reduce water consumption n ow. If all water users can voluntarily reduce their water consumption by 20% over previous year’s usage, it is likely that the need to implement mandatory water rationing can be delayed or eliminated. Staff will continue to monitor the water supply situa tion and report to Council in May /June on the impact of the voluntary efforts . In the report staff may recommend that 3 Council adopt the Stage 1 Water Shortage measure , a mandatory 15% reduction in water usage from the previous year’s usage . This would tri gger Water Use Allowances for each residential and commercial water customer if one or more of the following conditions are met:  D rought conditions continue into the summer and groundwater levels drop .  W ater use reductions are not met .  MWD restricts its su pplies . While it is less than the 20% voluntary reduction, the mandatory reduction would require reduction by all water users. Those who achieve 20% reduction through voluntary efforts would not be required to make additional reduction. W ater self -suf ficiency ta kes commitment and investment. Many residents and businesses have already taken steps to manage their own water use more efficiently. In 2013 more than 400 rebates were provided for water savings products with an estimated 3 million gallons of w ater savings. Rebates are available for installing sustainable landscaping, water -saving drip irrigation and sprinklers, rain barrels, cisterns, toilets, urinals , and much more. There are larger rebates for specific businesses such as fitness centers, L aun dromats, and public agencies. The Office of Sustainability and the Environment will increas e its outreach efforts to alert the community about the Water Shortage Advisory and the need for enhanced conservation. Additional outreach will include ads in loc al papers, a street banner over Main Street, period ic press releases, updates to City’s website, and presentations at community events. As part of the outreach, s taff will emphasize three ways to save water: 1. Check for and fix leaks. Running toilets are ve ry common and are often ignored , bu t can waste thousands of gallons each day. 2. Cut back watering garden s by just a few minutes each watering cycle. 4 3. Replace toilet s with more water -saving ones . All new toilets sold in California are 20% more effic ient than models sold in 2013. A $50 rebate is available until the end of June 2014 for toilets with a WaterSense label. By taking proactive steps now and requesting a voluntary enhancement to Santa Monica’s current Water Shortage Advisory from 10% reduction to a 20 % reduction, the City is reinforcing the need to undertake sound management of water resources and with successful reductions, delay/eliminate the recommendation to implement mandatory water conservation in the community in 2014 .
