D°a MINUTES OF A REGULAR MEETING BOARD OF APPEALS AND ADVISORS CITY OF CHULA VISTA, CALIFORNIA November O5, 2012 Conference Room #137 5:15 PM 276 Fourth Ave. Chula Vista, CA 91910 MEMBERS PRESENT: Sanfilippo, Lopez, Sides, Meservy, West and Starkey MEMBERS ABSENT: Jones (excused) CITY STAFF PRESENT: Lou EI-Khazen, Building Official OTHERS PRESENT: Dan Martin, Otay Water District CALL MEETING TO ORDER: Chair Sanfilippo called the meeting to order at 5:15 p.m and took the roll call. Building Official EI-Khazen noted Member Jones had contacted him ahead of time and said he would not be able to attend tonight's meeting, as he would be out of the country. The Committee voted to excuse his absence. Mr. EI-Khazen introduced to the committee the new Board of Appeals & Advisor Member Gina Starkey. 1. ROLL CALL: Members present constituted a quorum. 2. APPROVAL OF MINUTES: November 14, 2011 MSC (CS/LM) (6-0-0-1) Approve the Board of Appeals & Advisors minutes of November 14, 2011. Motion carried with Member Jones absent. 3. NEW BUSINESS: A. Elect new Chair and Vice-Chair for fiscal year 2012/13. Nominations were opened for Board Chairman and Vice Chairman. Chair Sanfilippo asked the committee if there was anyone interested in being nominated. The committee responded they were satisfied keeping Chair Sanfilippo and Vice Chair Sides in their current positions and no further nominations were made. A motion for approval was made and passed. B. Proposed residential clothes washer graywater stub-out ordinance (information/discussion item) Mr. Lou EI-Khazen, Building Official gave some background information and provided a brief power point presentation going over the proposed amendment to the Chula Vista Municipal Code of adding Section 15.28.020 Residential Graywater Stub-out. The proposal calls for new regulations to incorporate clothes washer graywater plumbing stub-out in new residential development to facilitate the later installation of a graywater irrigation system used for shrubs and trees only. The ordinance will only apply to detached single-family dwellings, duplexes and a building permit is not required. Other residential building types (multi-family and townhomes) were considered but because of the small lot size and impracticality for multi-family buildings staff is recommending excluding these types of residential units from the requirements. The building official proceeded to go over pre-plumbing and stub-out implementation standards. Diagrams in the power point presentation were used to illustrate the different methods of installing the stub-out. Based on staff's research the incremental cost for installing the pre-plumbing and stub-out during new construction is estimated to be between $200 and $350 depending on the location of the laundry room in the house in relation to the most useful location for the exterior stub-out. To assist homeowners who are interested in utilizing clothes washer gray water systems, they are working with the Conservation Group to create a Best Practices Guidebook to inform and educate the homeowners on how to install and use it properly. Lou discussed the issue brought up by Otay Water District concerning the use of auxiliary water and RP device requirements in Title 17. Under the current regulations, an auxiliary water supply is considered unapproved and cross connection creates the potential of potable water being Board of Appeals & Advisors Page 2 D D ~ November 5, 2012 Meeting Minutes contaminated. Having these two requirements in the regulations triggers the requirement for_an-RP device, which would be installed next to the water meter. A device like this costs $300-$500 and that doesn't include labor. In addition, the regulations also require that the water company inspects it annually and a $200 inspection fee (by water company) is charged to the homeowner. Meeting these conditions may make it economically unfeasible for homeowners and discourage them from wanting to use the graywater system. Mr. Dan Martin, representing the Otay Water District, acknowledged that different agencies are at odds with the Title 17 requirement and the water district has reached out to the state to try and resolve this issue. They are informing them there are other measures in place being implemented by different cities, and were asking the state to provide a provision that would lessen the requirement in Title 17. Committee Members Concerns/Comments: The Committee Members were all for conservation endeavors and liked the concept of having a graywater system available; however, they expressed concerns that: • Too many variables involved might give the resident the opportunity to install the system incorrectly and ruin their landscaping. Which would not make it cost effective for anybody whether that be savings in water or environmentally. • Regardless of the back flow requirement, should they make the homeowner pay for an option they might never use? The city should ask the developers to have it as an option of installing the system if the homeowner desires it. • Not economically feasible in this economic climate • Need to get some kind of waiver from the state on Title 17 requirement in order to make it feasible and encourage residents to use. • Since 60-70% of water is used for landscaping we should be looking at other methods of conserving water i.e. drought tolerant plants, and hardscape that are more cost effective. Emphasize those methods more than the use of graywater. It was the consensus of the committee in its current state the proposed ordinance was not practical and they probably wouldn't be in favor of recommending it. Mr. EI-Khazen thought the city's perspective on this was if the homeowner installed the stub-out on his own there would be a greater potential for problems, whereas, if the system was already installed and the homeowner uses the Best Practices Manual it would be less of an issue. 4.

By 2050, San Diego County's demand for water is expected to increase by 37% as a result of population and economic growth. In addrtron, prolonged,. droughts exacerbated by climate change could reduce water Supplies from rmpo~ted sources~bj~ 20% or morel These climate - change impacts could limit ixnpprted water availability, increase utility costs for residents and businesses, and lead to higher demand for local water sources.

"Focus 2050 Study: San Diego's Changing Climate." 2008 Z Based on 20 gallons per load, 7 loads per week. Item No.: Meeting Date: xx/xx/2013 Page 3 of 4 StafF is proposing two approaches to installing the pre-plumbing and stub-out. One involves a separate clothes washer graywater standpipe, similar to the standard clothes washer sewer standpipe, where the homeowner can manually move the washer discharge pipe between the two outlet boxes. The other involves a 3-way diverter valve where the valve can be positioned to direct the graywater to either the sewer standpipe or irrigation stub-out. The proposed installation requirements are outlined in the City of Chula Vista Clothes Washer Graywater Pre- Plumbing and Stub-Out for New Residential Construction (Exhibit A to the proposed Resolution). Realizing that there might be other acceptable code co~aplying approaches, the proposed Ordinance and installation requirements give the Burldirig Official the ability to approve equivalent alternate methods and/or materials. Fu~termore, realizing that some properties and building layouts may not be suitable for a gfay~V~ter system, the proposed ordinance gives the Building Official the ability to modify or waive the`tequirements when it can be demonstrated to his satisfaction that compliance with the requirements is impractical due to construction or physical constraints, or due to site and/or soil conditions. Homeowners must ensure that when they later installti>a grayv~~ter irrigation system on their property that it is designed and installed safely, is consrstentwith applicable code requirements, and is operated in a manner that causes no harm or damage tb_themselves or neighbors. To assist homeowners who are interested in utilizing clothes washer gray water systems, staff will develop a "best practices" manual describing proper installation methods for installing the systems. The manual will address clothes washer gray water sysCerrts at both naw homes (to complement the new stub-out requirement described above) and at existix}g xesidenbes. Special emphasis in the guides will also be placed on maximizing the°system s eff~ctfweness, protecting human health, and avoiding water runoff. The installation of a stub-Rut at time of new constrggTjon facilitates the later installation and use of a graywater system in fesidences. Based on staff's research, the incremental cost for installing the pre-plumbing acid stub=out during neiv consi~uction is estimated to be between $200 and $350 depending on the location ©f the laundry'room in the house in relation to the most useful location fu'r the exterioratrilz-out. In addition tq presenting the proposed'Ordinance and Resolution to the Board of Appeals and Advisors (B4A&A) and the Resources Conservation Commission (RCC), on September 19, 2012, staff presented them to the Development Services Oversight Committee (DSOC). The DSOC consists of representatives from the design and construction industries and engaged members of the genefal pudic. Committee members raised some issues that were addressed by staff and did not express any opposition to what is being proposed. Exniration of Local Standards Pursuant to State law, local amendments to California building codes will no longer be in effect the date new California building codes take effect. Therefore, if adopted, the proposed local standards will have to expire upon the date the 2010 California Plumbing Code is no longer hi effect; currently projected to expire January 1, 2014 when the 2013 State codes take effect. If City Council adopts the proposed Ordinance and Resolution, staff will reintroduce the locally Item No.: Meeting Date: xx/xx/2013 Page 4 of 4 adopted standards for City Council's consideration and adoption at the time staff brings forward the new building codes to Council for adoption. DECISION MAKER CONFLICT Staff has determined that the recommendations requiring Cotmcil action are not site specific and consequently the 500 foot rule found in California Code of Regulations Section 18704.2(a)(1) is not applicable to this decision. Staff is not independently aware, nor has staff been informed by any City Couneilmember, of any other fact that may constitute a basis for a decision maker conflict of interest in this matter.

ORDINANCE OF THE CITY OF CHULA VISTA AMENDING CHAPTER 15.28 OF THE CHULA VISTA MUNICIPAL CODE - BY ADDING SECTION 15.28.020, RESIDENTIAL GRAYWATER STUB-OUT WHEREAS, on May 3, 2011 City Council approved Resolution 2011-076 in which City CoLmcil adopted the Climate Adaptation Strategies and approved their implementation; and WHEREAS, the adopted Climate Adaptation Strategies will help reduce the City's future risks and costs from expected local climate change impacts; and WHEREAS, the Implementation Plan for Strategy #4, Local Water Supply and Reuse, proposed adopting new regulations to incorporate clothes washer graywater plumbing shib-out in new residential development; and WHEREAS, the Department of Water Resources and the Department of Housing and Community Development adopted graywater regulations in the 2010 Californian Plumbing Code Chapter 16A, Part I; and WHEREAS, clothes washer graywater systems constructed according to Chula Vista Clothes Washer Graywater Pre-Plumbing and Shib-Out for New Residential Construction and operated according to the 2010 California Plumbing Code Chapter 16A provide a safe method of reducing potable water demand; and WHEREAS, a clothes washer graywater system can save a typical single-family dwelling up to 7,000 gallons of potable water per year; and WHEREAS, the installation of a stub-out at time of construction greatly facilitates the use of graywater in residences; and WHEREAS, the City Council specifically and expressly finds and declares that adding section 15.28.020 to Chapter 15.28 is necessary due to Local climatic conditions. As a result of prolonged droughts exacerbated by climate change, it is anticipated that water supplies from imported sources are reduced, and furthermore, as a result of population and economic growth, demand for water is expected to increase. These impacts could limit imported water availability, lead to higher demand for local water sources and increase utility costs. Requiring single-source graywater stub-out in new residential development facilitates the use of graywater for irrigation which in turn helps address these water-related climate change impacts. NOW THEREFORE the City Council of the City of Chula Vista does hereby ordain as follows: SECTION I. ENVIRONMENTAL REVIEW Ordinance No. Page 2 That the City Council has reviewed the proposed activity for compliance with the California Environmental Quality Act (CEQA) and has determined that the activity falls within the Class 8 Categorical Exemption pursuant to California Code of Regulations Title 14, Chapter 3, Article 19 (the "State CEQA Guidelines") section 15308 and therefore is exempt from environmental review; and notwithstanding the Class 8 Categorical Exemption, the City Council has further determined that there is also no possibility that the activity may have a significant effect on the environment; therefore, pursuant to section 15061(b)(3) of the State CEQA Guidelines the activity is exempt from the provisions of CEQA. SECTION II. CHULA VISTA MUNICIPAL CODE That the City Council does hereby find and determine that Chapter 15.28 of the Chula Vista Mtmicipal Code is hereby amended by adding Section 15.28.020, Residential Graywater Stub-out, as follows: 15.28.020 Residential Graywater Stub-out. All new detached single-family dwellings and duplexes shall include asingle-source clothes washer gaywater outlet and an outside stub-out to allow the later installation of a clothes washer graywater irrigation system that complies with the requirements of Section 1603A.1.1 of the 2010 California Plumbing Code. The outlet and stub-out shall be installed in accordance with the Chula Vista Clothes Washer Graywater Pre-Plumbing and Stub-Out for New Residential Construction or an equivalent alternate method and/or material approved by the Building Official. The provisions of this Section may be modified or waived when it can be satisfactorily demonstrated to the Building Official that compliance with these regulations is impractical due to construction or physical constraints, or due to site and/or soil conditions. SECTION III. EFFECTIVE DATE This ordinance will take effect and be in force thirty days after its final passage. SECTION IV.

NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Chula Vista that it hereby adopts the Chula Vista Clothes Washer Graywater Pre-Plumbing and Stub-Out for New Residential Construction, attached as Exhibit "A," as the installation requirements in the City of Chula Vista. Presented by Approved as to form by Gary Halbert, P.E., AICP Glen R. Googins Assistant City Manager/Development City Attorney Services Director ExxIBIT a ~~tr~ , Clothes Washer Graywater Pre-Plumbing and ciw of Stub-Out for New Residential Construction CHULA VISfA These requirements, or an equivalent alternate method and/or material approved by the Building Official, are applicable in all new detached single family dwellings and duplexes. There are two basic approaches to installing the pre-plumbing and stub-out for a future clothes washer graywater system in newly constructed dwelling units. Both methods are installed adjacent to the regular clothes washer standpipe to allow the clothes washer to drain into the regular sewer standpipe (leading to the building sewer) or be diverted to a graywater stub-out on the exterior of the building. The following are the two methods: Configuration #1 involves a separate graywater standpipe installed adjacent to the regular clothes washer standpipe. This can be done by installing an additional outlet box dedicated for the graywater standpipe. The following installation requirements apply: • The standpipe shall be vented (an air admittance valve is acceptable) and trapped, and all plumbing materials shall be 2-inch in size. • The standpipe shall have a 2-inch overflow pipe leading downward to the regular washer sewer standpipe. • The graywater standpipe outlet box shall be as close as possible to the sewer standpipe so that the flexible washing machine wastewater discharge pipe can be manually moved between the two outlet box drainage pipes to either flow into the sewer or to a future graywater system attached to the stub-out. • The plumbing system must have aminimum'/~" per foot slope towards the exterior stub- out. Configuration #2 uses a 3-Way Diverter Valve connected to the end of the flexible washing machine wastewater discharge pipe. The valve position directs the graywater to either the regular standpipe leading to the sewer or to the graywater sub-out. The following installation requirements apply: • The diverter valve and all additional plumbing materials shall be minimum 1-inch in size or greater. • The graywater stub-out shall have a vacuum breaker installed at the highest point in the connection, either inside or outside. • The diverter valve must he accessible and securely fastened to the interior wall at the clothes washer. The following general requirements apply to both configurations: • Permanent labeling. o Regular standpipe leading to the building sewer and diverter valve in position to feed into the sewer standpipe must be permanently labeled "Building Sewer." Page 1 of 2 EXHIBIT A o Standpipe dedicated to feed the graywater stub-out and diverter valve in the - position to feed the graywater stub-out must be permanently labeled "Graywater to Landscape." o Exterior graywater stub-outs must be permanently labeled "Graywater Stub-Out. Caution-Unsafe Water." o Sections of the graywater piping 5-feet or longer must be labeled "CAUTION: NON-POTABLE WATER, DO NOT DRINK." • An operation and maintenance manual shall be provided. Directions shall indicate the manual is to remain with the building throughout the life of the system and indicate that upon change of ownership or occupancy, the new owner or tenant shall be notified the structure contains a graywater stub-out or system. • Stub-out o Must extend a minimum of 3-inches outward past the exterior wall. o Must have a rubber cap with a stainless steel tightening draw band to keep it closed when not conducting graywater. o Exterior stub-outs should measure between 18-inches and` 48-inches above finished exterior grade. The higher the better to assist with the gravity flow of the system but not to exceed 48" above finished exterior grade. o The stub-out should be as close to the largest area of landscaping as possible. • All exterior materials shall be protected from UV rays by a latex paint, except for the vacuum breaker device. • All work and materials used shall conform to the California Plumbing Code in effect at the time of installation. • Both ends of the graywater stub-out plumbing need to be identified on the plans. • The graywater plumbing and stub-out is required wherever the clothes washer outlet box is installed in the building.
