Walter, Public Works Director Prepared By: Ron Combs, Keith Pellemeier, Urban Forest Supervisor SUBJECT: APPEAL OF THE TREE COMMITTEE'S DECISION TO ALLOW THE PROPERTY OWNER TO REMOVE ONE PINE TREE AT 546 HIGUERA RECOMMENDATION Adopt a resolution denying the appeal of the Tree Committee's decision to allow the removal of one pine tree at 546 Higuera, thereby allowing removal of the pine tree by the property owner. DISCUSSION Background On, July 31, 2009, Steve Franzmann of Greenvale Tree Service, as the agent for the property owner, applied to remove one pine tree at 546 Higuera. A large limb had split off and was lying on the power line. Mr. Franzmann secured the broken branch to the tree to stabilize it temporarily. (Attachment 1) The City Arborist reviewed the tree removal application, visited 546 Higuera and could not make findings supporting removal under Municipal Code, Chapter 12.24, Tree Regulations, 12.24.180.C.5, which provides: When tree removal is not related to property development, the city arborist may authorize a tree removal after finding any of the following circumstances: a. The tree is a hazard to life or property, and removing it is the only feasible way to eliminate the hazard; b. The tree is dead or dying or damaged beyond reclamation; c. The tree is causing severe root damage to public or private property, and removing the tree is the only feasible way to eliminate the damage. The pine tree did not technically meet the above criteria and the City Arborist did not authorize its removal. When the City Arborist cannot approve removal, and the tree removal is not part of property development, the request is brought before the Tree Committee for its consideration. Tree Committee Review and Decision The removal request was heard at the August 24, 2009 meeting of the Tree Committee. Mr. Franzmann cited the reasons the owner wanted to remove the pine tree: to eliminate the current hazard and to reduce future liabilities. Half of the main trunk was gone and retaining the tree was not advisable because of the decay. r Appeal of Tree Committee Decision for 546 Higuera Street Page 2 Mr. Craig Steffens, 546 Higuera, Space #25 represented several neighbors who favored retaining the tree. The Committee discussed removal and replanting options, focusing on riparian plantings along the creek bank. Mr. Root, moved to approve the removal request, based on promoting good arboricultural practice, and required two native sycamores be planted along the creek. Ms. Dollar seconded the motion stipulating the new trees be maintained and watered to ensure they survive. The motion passed unanimously. (See Attachment 3) Appeal On, September 3, 2009, the City Clerk's office received an appeal of the Tree Committee's decision at 546 Higuera, from Mr. Steffens. Mr. Steffens feels the tree has many more years with proper pruning. (See Attachment 4) Basis for Staffs Recommendation Due to the large section of trunk that split off from this tree, the type of heavy topping required reducing the risk of further failures, evidence of western gall rust, and the inevitable decline of this tree, staff concurs with the Tree Committee's decision to approve the removal request and require replacement plantings. San Luis Obispo Municipal Code, Tree Regulations, 12.24.180.C.6.a states: When the city arborist cannot authorize removal, the tree committee shall review the application and may authorize removal if it finds one of the following circumstances: a. The tree is causing undue hardship to the property owner. Normal routine maintenance does not constitute a hardship, i.e., cleaning of gutters, leaf raking, or root intrusion into a failed sewer lateral, etc.; b. Removing the tree promotes good arboricultural practice; c. Removing the tree will not harm the character or environment of the surrounding neighborhood. FISCAL IMPACT There is no fiscal impact to the City in denying the appeal. ALTERNATIVE Approve the appeal. The City Council could choose to approve the appeal and deny the property owner's request to remove the pine tree. The Council could find there to be an overriding consideration which recognizes the value of this particular tree to the neighborhood. Should the Council decide to make this finding, staff recommends the owner be required to complete risk reduction pruning of the tree, and complete the recommended replacement tree planting at this time as this tree will inevitably succumb to disease. In this way, risk to park PK3- a I Appeal of Tree Committee Decision for 546 Higuera Street Page 3 residents is minimized and replacement trees will be established by the time the tree has to be removed.

Steve Franzman, Greenvale Tree Co., applicant's representative, discussed the large limb, previously dropped and stated approximately half of the main trunk was now gone and felt the structure beneath would soon.fail. He felt pruning would create too rhuch topping, due to the amount of present decay. He also stated there was evidence of gall rust. Mr. Combs agreed with Mr. Franzman's assessment and.,suggested if it were approved for removal,the applicant could plant something riparian. He said it would need crown r reduction and the wound would be slow to heal and it may succumb to disease. Replacement with a native would probably be better. MrAteffan, Space#25, stated he represented several neighbors from the:park that favored retaining the tree. He suggested pruning should be attempted and felt proper maintenance of the tree would benefit its health. He felt the tree greatly improved the area. Jeannie Hanys2f, Space#15,reported that there had been past neglect in maintaining the trees.on behalf of the property owner. She stated too many trees had already been removed and the site needed the shade trees provided. Katherine Schmidt, Space#28, stated that branches were encroaching into the power ` lines. She Pelf pruning and sealing would mitigate decaying concerns. She agreed the entire property was becoming too barren. Mr.Root discussed the urban forest concept of tree-age planting/staggering and favored removal of the failing eucalyptus and requiring two replacement trees. Ms.Dollar agreed stating the tree would never be the same again and felt two shade trees should be specifically chosen. Mr.Root moved to approve,the removal request,based on promoting good arboricultural practice, and required two 15-'gallon replacement trees to be chosen froni•the-Master Street Tree list and planted within 45 days of issuance of permit along the creek bank. He further suggested California sycamore as a species and that one tree should be planted at the removal site and one p�lpnted somewhere else on the property. Ms. Dollar seconded the motion,with the approved stipulation that the treestneeded to be watered,and maintained.for five years and if either did not survive, they were to be replaced accordingly. The motion passed unanimously. / I ATTACHMENT 4 Filing Fee:.$268:06' Paid Date Received NIAECEIVED city of sae lids oBlspo •11"1S6C110N4 SEP 0 3 2.009 APPEAL TO THE CITY COUNCIL SECTION 1.

Staff received an appeal of the recommended removal of a tree at 546 Higuera #12. The appellant will be appealing the tree removal and seeking a waiver of the appeal fee. Because of this "quirk" to this particular appeal, the tree removal crew was not notified of the appeal until this morning, as they were readying the tree for removal. When advised of this circumstance, City Arborist, Ron Combs, went to check on the status of the tree at 546 Higuera #12. Thankfully, the tree is still there. The crew did trim off a branch and had cut away the part of the tree that had split off some time ago. Ron said that what was trimmed from the tree was already broken. You will receive a complete report on this matter when it is before you for appeal. In the meantime, the tree has indeed been mistakenly trimmed, but has most certainly been retained until a final decision by Council has been made.

Christine will contact the appellant and ask for a written request to waive the appeal fee. We will put the fee waiver item on the October 6th Council Agenda, and Christine will prepare the staff report based on that request. Depending on the outcome, we will put the actual tree appeal item on the October 20th agenda, so that the Clerk's office can do the required legal notice for the hearing and so staff does not spend time preparing an item that may not be heard. We don't know for sure, but suspect that if the fee waiver request is denied, he may decide not to pursue the tree appeal at all. Jay D. Walter, PE Public Works Director From: Dietrick, Christine Sent: Monday, September 14, 2009 9:08 AM To: Walter, Jay Cc: Lowell, Jonathan P Subject: RE: Fee Waiver and Tree Appeal Jay—Jonathan will be at the LOCC conference beginning on Wed., so we may want to talk about this before he leaves. I think we could agendize the waiver and appeal on the same night, with the waiver item preceding the appeal. If council denies the waiver request, Craig can either present us with a check and proceed to the appeal hearing or the appeal item will drop from the agenda. If they grant the waiver, obviously we proceed. J. Christine Dietrick Asst.

I presume this needs to go on the 60- day Agenda within our mandated appeal timeframe and we will be coordinating on the additional issue of the request for a fee waiver alongside the appeal. Thanks. From: Lowell,Jonathan P Sent: Thursday, September 10, 2009 10:21 AM To: Dietrick, Christine; Pellemeier, Keith; Stanwyck, Shelly; Cano, Elaina; Walter, Jay Subject: Fee Waiver and Tree Appeal On the tree appeal fee waiver issue,we should address it next week. FYI, I received a call from Mark London, manager of the mobilehome park where the subject tree is located. He was angry about the appeal, thought it unfair, believes it was filed in retaliation against him. He understands appeal process, but is bothered by the fee waiver request. He wants us and Council to consider that the appellant owns not only his mobilehome but one or more others in the park that he rents out to other people, thus suggesting that he is not indigent and has various sources of income. We will include this in our calculus, somehow. Jonathan Jonathan P.

Thanks, Elaina From: Lowell,Jonathan P Sent: Wednesday, October 07, 2009 11:49 AM To: Cano, Elaina Cc: Pellemeier, Keith; Dietrick, Christine; Walter, Jay; Stanwyck, Shelly Subject:Tree Appeal by Steffens re Mission Trailer Park(Rossi owned, I think) Elaina, In reply to your voicemail, SLO MC section 1.20.040 says the clerk shall set the matter for hearing at the next reasonably available council meeting, but in no event later than forty fie calendar days after the date of the filing of such notice of appeal with the city clerk. Purpose is so as not to unduly burden through delay one whose entitlement is involved in the appeal. Steffens wants to delay or stop and action, so postponing appeal is not an issue for him, but it could be for the property owner who sought to remove tree. That is why I asked question about what property owner is aware of, has Keith contacted him and so forth. I think it far easier for PW to get a report together today or tomorrow so we can stay on the October 20 agenda (still a couple of days late, but close enough). If item is considered later, property owner has a very good argument to say appeal not timely heard, so he can proceed, and he just might. That will 10/8/2009 Page 2 of 2 leave us with Steffens maybe pursuing some sort of action against the City for improperly processing the paperwork(won't get very far, but a pain).

One such policy tool is an ordinance to encourage or even require rainwater harvesting. The best rainwater harvesting policies protect water as a human right,protect public health and promote sustainability. Through a combination of incentives,taxes and penalties, meaningful water conservation can be achieved. Restrictive policies can create barriers to implementation and add unnecessary costs,but well-designed policies will encourage rainwater harvesting and help to maximize the benefits of implementing these systems. When developing a rainwater catchment policy or ordinance, consider the following criteria. Your policy or ordinance should be: • Economically viable and ecologically sustainable • Achievable and measurable • Easy for the public to understand and simple to implement with streamlined processes • Reviewed by actual rainwater harvesting professionals • Include education and technical training for the public, staff and elected officials • Include financial support such as subsidies or grants for low-income communities Semantics are also important to consider. How you define rainwater can greatly affect outcomes. Avoid classifying rainwater as stormwater, runoff, greywater or wastewater. Hundreds of thousands of rainwater harvesting systems exist throughout the world. While in many places in the U.S. rainwater harvesting is actually banned because of"first come, first serve" laws dating back a century,a few American cities actually require that new buildings use cisterns to store roof runoff. Legislation around the U.S.: Tucson, Arizona: In October of 2008, the city of Tucson, Arizona became the first municipality in the country to require developers of commercial properties to harvest rainwater for landscaping. The new measure—approved by a unanimous vote by the City Council—requires that new developments meet 50%of their landscaping water requirements by capturing rainwater. The new rule goes into effect June 1, 2010. Santa Fe County,New Mexico: Residences with 2,500 sq ft or more area must install an active rainwater catchment system comprised of cisterns. All commercial developments are required to collect all roof drainage into cisterns to be reused for landscape irrigation. Albuquerque and Bernalillo County,New Mexico: Residences with 2,500 sq ft or more area must install an active rainwater catchment system comprised of cisterns. All commercial developments are required to collect all roof drainage into cisterns to be reused for landscape irrigation. State of Texas: In 2001, the Texas legislature amended the Texas Tax Code to allow taxing units of government the option to exempt from taxation all or a part of the assessed value of the property on which water conservation modifications have been made. City of Austin, Texas: The residents of the city of Austin can buy rain barrels at subsidized rates and also they can claim a rebate for the installation of approved cistern systems. Commercial/industrial properties can collect rebates up to $40,000 for the installation of rainwater harvesting and Grey water systems. City of San Antonio, Texas: The San Antonio Water System's (SAWS)will give up to 50% rebate on the cost of new water-saving equipment, including rainwater harvesting systems,to its commercial, industrial and institutional customers. Rebates are calculated by multiplying acre-feet of water conserved by a set value of$200/acre-foot. State of Arizona: The Government announced a one-time tax credit of 25% of the cost of water conservation system (the maximum limit is$1,000) for its residents. The water conservation system is defined as any system, which can harvest residential grey water and/or rainwater. The builders are eligible to get the tax credit up to $200 per residence unit constructed with a water conservation system. Any citizen in this state who has purchased a water harvesting system on or after January 1 st, 2008, can apply for the Arizona tax credit. There is roughly $250,000 per year allocated for these tax credits. Legislation around the world: Mumbai, India: The state government has made rainwater harvesting mandatory for all buildings that are being constructed on plots that are more than 1,000 sq m in size. New Delhi, India: Since June 2001, the Ministry of Urban affairs and Poverty Alleviation has made rainwater harvesting mandatory in all new buildings with a roof area of more than 100 sq m and in all plots with an area of more than 1000 sq m, that are being developed. Furthermore, the Central Ground Water Authority (CGWA)has made rainwater harvesting mandatory in all institutions and residential colonies in notified areas (South and southwest Delhi and adjoining areas like Faridabad, Gurgaon and Ghaziabad). This is also applicable to all the buildings in notified areas that have tubewells. Haryana, India: Haryana Urban Development Authority(HUDA) has made rainwater harvesting mandatory in all new buildings irrespective of roof area. Himachal Pradesh, India: All commercial and institutional buildings, tourist and industrial complexes, hotels etc, existing or coming up and having a plinth area of more than 1,000 square meters will have rain water storage facilities commensurate with the size of roof area. No objection certificates, required under different statutes, will not be issued to the owners of the buildings-unless they produce satisfactory proof of compliance of the new law. Toilet flush systems will have to be connected with the rainwater storage tank. It has been recommended that the buildings will have rain water storage facility commensurate with the size of roof in the open and set back area of the plot at the rate of 0.24 cft. Per sq m of the roof area. Bangalore, India: In order to conserve water and ensure ground water recharge,the Karnataka government in February 2009 announced that buildings, constructed in the city will have to compulsorily adopt rain water harvesting facility. Residential sites, which exceed an area of 2400 sq ft(40 x 60 ft), shall create rain harvesting facility according to the new law. Victoria, Australia: Since July 2005, new houses and apartments in Victoria must be built to meet the energy efficiency and water management requirements of the 5 Star standard,which requires either a rainwater tank for toilet flushing, or a solar hot water system. South Australia: New homes are required to have a rainwater tank plumbed into the house. Sydney and New South Wales, Australia: The BASIX (Building And Sustainability Index) building regulations call for a 40%reduction in mains water usage. In order to meet the BASIX target for water conservation, a typical single dwelling design must include a rainwater tank or alternative water supply for outdoor water use and toilet flushing and/or laundry, among other water conservation devices. Gold Coast, Australia: Construction of 3,000-litre (800-gallon) rainwater tank is mandatory in the Pimpama Coomera Master Plan area of Gold Coast. This is for all homes and businesses centers connected to the Class A+recycled Water system(those approved for development after 29 August 2005). The tank should be plumbed to their cold-water washing machine and outdoors faucets. Oueens land, Australia: Residents can get a rebate of up to $1,500 for the purchase and installation of home rainwater storages. Germany: Rain taxes in Germany are a great example of internalizing externalities for a more fair system. Fees are collected for the amount of impervious surface cover on a property that generates runoff directed to the local storm sewer. That means that the more the rainwater is caught and conserved, the less rainwater runs off and is added to the storm drains. Less runoff allows for smaller storm sewers, which, in turn, saves construction and maintenance costs at the site. Thus there is a large incentive to convert impervious pavement/roof into a porous surface. Rainwater catchment policy has implications not only for addressing water shortages, but also for reductions in energy use and related carbon emissions, as treating water consumes a lot of energy(in California, municipal water supply and wastewater treatment systems account for about 35%of energy used by municipalities.). As local governments begin to face mandatory emissions reductions, saving water may become a cost-effective way to shave off carbon emissions that requires little capital investment compared with other strategies.

This MOU defines the following roles for the SFPUC,DBI,and DPH with regards to rainwater harvesting: • The SFPUC will create and distribute guidance material on rainwater harvesting.The material will cover system design,system components,allowable uses,owner responsibilities,and permitting requirements. The SFPUC will encourage all rainwater harvesters to notify the SFPUC with the design specifications of their systems for research purposes. • DBI will issue permits for construction of properly designed rainwater harvesting systems for non-potable uses that meet the minimum criteria described in this MOU and in guidance materials prepared by the SFPUC.DBI will be responsible for review of permit applications and inspection of rainwater harvesting systems that require permits(not all systems will require permits). • DPH will review rainwater harvesting projects that propose any residential indoor uses of rainwater otherthan toilet flushing to assure the protection of public health. This MOU includes the following information about rainwater harvesting as a record of what the SFPUC,DBI,and DPH have agreed upon: • It describes the rainwater harvesting system components that the SFPUC,DBI and DPH agree are necessary for the safe and functional use of rainwater for non-potable applications; • It lists the permitting requirements for the installation of rainwater harvesting systems in the City and County of San Francisco. Responsibility Proper system design,maintenance,and use are the responsibility of the system owner,not the SFPUC,DBI,or DPH. Background Rainwater harvesting is the practice of collecting and using rainwater from impervious surfaces such as roofs or patios, etc As climate change and population growth threaten the viability and stability of the water supply system,San Francisco must broaden its water supply portfolio,reduce the use of potable water for non-potable applications,match the necessary degree of water treatment to the degree of contamination,and match the cleanliness of the water to the proposed use.Rainwater harvesting achieves each of these four goals. In addition,rainwater harvesting yields multiple measurable benefits for San Francisco's urban watershed. It: • Offsets the volume of potable water used for non-potable applications such as irrigation and toilet flushing; • Keeps relatively clean water out of the combined sewer system thereby enhancing the performance and lengthening the life of the City's combined sewer infrastructure; • Reduces the volume and peak flows of stormwater entering the sewer,thereby reducing flooding and combined sewer discharges; • Reduces the energy and chemicals needed to treat stormwater in San Francisco's sewage treatment plants; and • Reduces the energy expended transporting potable water from distant sources. San Francisco has already begun to remove barriers to rainwater harvesting from the plumbing code.In 2005,City staff amended the plumbing code via Ordinance 137-05,making it legal to disconnect downspouts from the combined sewer and direct rainwater from roofs to alternative locations such as rain gardens,rain barrels,and cisterns. The relevant Plumbing Code is Section 306.2.,which reads"Roofs,inner courts,vent shafts,light wells or similar areas having rain water drain,shall discharge directly into a building drain or building sewer,storm drain,or to an approved akernate location based on approved geotechnical and engineering designs." Page 3 of 7 i i Rain Barrels Rain barrels are containers,typically between 50 and 100 gallons,designed to capture rainwater runoff from roofs for use in irrigation,vehicle or equipment washing or other non-potable applications.This MOU considers storage containers of over 100 gallons to be cisterns,subject to all permitting requirements for cisterns listed in the cistern section of this MOU. Allowable uses Water collected in a rain barrel may be used for irrigation and vehicle washing.Water collected in a rain barrel may not be connected to either indoor or outdoor plumbing in any way;nor may it be pressurized or sprayed. Required components for rain barrels • Storage container • Sealed lid • Screened openings • Spigot and/or hose bibb • Screened air vent • Overflow pipe Siting and design • Rain barrels must be sited in a stable,flat,shady area. • Rain barrels may not be connected to indoor or outdoor plumbing without a permit • Rain barrels may not be connected to electrical devices without a permit. • Overflow may not discharge water across a public right-of-way. • Overflow to the collection system must include an air gap. • Outdoor spigots on properties utilizing rain barrels must have an atmospheric vacuum breaker attached. • Rain barrel overflow locations must be designed to prevent nuisance flows to adjacent properties.Appropriate overflow discharge locations are: o Approved drain(may require an inspection and a permit if no approved drain is available on the property) o Rain garden or other stormwater management facility(may require submittal of stamped drawing with percolation rates) Maintenance • Rain barrels must be kept clear of debris and all screens must be properly maintained to prevent mosquitoes or other vectors from breeding. • Rain barrels should be cleaned annually with a non-toxic cleaner such as vinegar. The catchment area draining to the rain barrel should be cleared periodically. For optimal performance,rainwater collected in rain barrels should be used as soon as possible after each rain storm to provide capacity to capture rainwater from the next rain event. Labeling Rain barrels must be labeled with the following symbols,indicating that they contain non-potable water;that,if not properly maintained,they can be a vector hazard;and that,if not properly sealed,they can be a drowning hazard. Permitting No permits are needed if an overflow pipe with an air gap is directed to an already approved drain or stormwater facility such as a rain garden.If there is no approved drain available,project proponents will need to install one.To do so,they will need a permit from DBI. Page 4 of 7 Cisterns Cisterns are typically larger than rain barrels,ranging from 100 gallons on a small residential site up to millions of gallons beneath schools and parks.Cisterns can be installed above ground,below ground,or on roofs,depending upon site conditions. Allowable uses Rainwater collected via a properly designed rainwater harvesting system may be used for irrigation,vehicle washing, heating and cooling,and toilet flushing.Other uses may be.proposed by the project applicant;additional permits and/or treatment requirements may apply. Required components for rainwater harvesting systems ❑ Roof surfaces serving as catchments for watering shall not include copper or materials treated with fungicides or herbicides. ❑ Gutters must be fully screened,continuous grade. ❑ Storage containers,tank liners,and tank coatings must be listed as food grade,or be approved for potable water storage.Containers must be opaque,watertight,vented,completely covered and screened. ❑ All openings must be screened. ❑ For above-ground systems,spigot and/or hose bibb for drawing water must be at least 2 inches from the bottom and must be labeled"NON-POTABLE". ❑ Overflow device must be equal in size to the total of all inlets and must lead to an approved discharge location with approved air gap. ❑ First flush diverter must be automatic self-draining with clean out. ❑ Safety labels(non-potable,vector hazard,drowning hazard icons shown in labeling section,below). ❑ Installation of gutters,leaders,downspouts,piping,fittings,valves,and screens must comply with California Plumbing Code." ❑ All plumbing materials must be listed with a recognized testing agency such as NSF or ANSI."* ❑ University of Southern California approved backflow prevention device located at the service connection with no fixtures between it and the water meter." ❑ Outdoor spigots must have an atmospheric vacuum breaker attached. *"Systems NOT connected to indoor plumbing need not include these components Siting and design • Cisterns must be sited in a stable,flat area. • No interconnections between cisterns collecting rainwater for non-potable uses and the municipal water source are allowed without approved backflow prevention devices. • Cisterns may not block the path of travel for fire safety access. • Cistern overflow locations,which can include rain gardens,additional cisterns or rain barrels,or a discharge point to the municipal collection system,must be designed to prevent nuisance flows to adjacent properties. • Overflow to the collection system must include an air gap. Maintenance • Gutters,screens,and vents associated with the cistern must be kept clear of debris and all screens must be properly maintained to prevent mosquito breeding. • The catchment area draining to the cistern should be deared periodically to prevent the accumulation of debris. • Cisterns should be cleaned annually with a non-toxic cleaner such as vinegar or,if necessary,flushed out or vacuumed. • All backflow prevention assemblies must be tested annually by the system owner using a certified tester approved by the City and County of San Francisco(see approved testers at htto://www.sfdph.org,doh/files/EHSdocs/ehsCrossflowdocs/cbbat0l 08.odf). Page 5 of 7 i Labeling Cisterns must be labeled with the following symbols,indicating that they contain non-potable water,that,if not properly maintained,they can be a vector hazard;and that,if not properly sealed,they can be a drowning hazard. s. Pipes that are connected to cisterns must also be labeled with these three symbols,and must be yellow.Spray painting or taping are acceptable methods for coloring pipe.The word"NON-POTABLE'must be printed on the pipe or tape. Permitting Project applicants proposing rainwater harvesting cisterns for non-potable uses must obtain the appropriate permits from DBI.To obtain the plumbing permit,requests for rainwater harvesting installations must be submitted to the Plumbing Inspection Division(PID).Requests must.include a site plan with elevations showing all rainwater harvesting equipment,piping,backflow prevention devices,overflow location,the location of all relevant appurtances,and a long- term maintenance plan for the system.Calculations showing the rainwater supply and demand for the intended use must be included.The plan must be drawn by a licensed PE or an American Rainwater Catchment System(ARCSA) accredited professional and stamped bythe same.Specifications and manufacturer's instructions for cisterns,pumps, switches,and filtration and/or disinfection devices must be included in the application. Project applicants proposing rainwater harvesting systems designed to collect and treat water for indoor uses other than toilet flushing,heating and cooling,or systems that interact with recycled water systems,will be inspected and permitted on a case-by-case basis and may require approval from DBI,DPH and the SFPUC. The following permits are needed for the installation of rainwater harvesting systems: • Plumbing permits are required for all rainwater harvesting systems servicing indoor fixtures,regardless of cistern size. • Electrical permits are required for all systems using pumps or other electrical equipment or controls. • Building permits are required for cistern footings,foundations,enclosures,and roof structures. • Grading and erosion control permits may be required for underground facilities. All systems must complywith the City of San Francisco Planning Code,the City of San Francisco and Building Code,and the 2007 City of San Francisco Plumbing Code,which consists of the 2007 California Plumbing Code,the 2006 Uniform Plumbing Code,and the 2007 City of San Francisco Plumbing Code Amendments. Modification of Memorandum of Understanding This Memorandum of Understanding(MOU)may not be modified except by written agreement executed and approved in the,same manner as this MOU.In the event of conflict with prior agreements between these parties,this MOU shall prevail over prior MOUS or prior agreements. In the event that more than five(5)projects with indoor uses other than toilet flushing are proposed by project applicants in a six(6)month period,this MOU should be revised to include a standard permitting process for such projects,rather than continuing the case-by-case approach specified here.

It does not have to be treated by a public agency and it can be used in both residential and nonresidential structures.This will provide requirements that would apply to rainwater harvesting systems and gray water systems for use with certain plumbing fixtures.All reclaimed water piping would be identified with purple background and black lettering(hence,purple pipe).(See Rainwater Harvesting Checklist handout) Community Environmental Health Services public Health 14350 SE Eastgate Way 1*0 Bellevue,WA 98007-6458 Seattle & King County 206-296-4932 Fax 206-296-4919 TTY Relay: 711 www.kingmuntV.gov/health RAINWATER HARVESTING CHECKLIST The Rainwater Harvesting and Connection to Plumbing Fixtures guidelines can be obtained at http://www.metrokc.gov/health/plumbinp-/guidelines.htm and you are strongly encouraged to review them. The following checklist provides additional information to assist you in the planning stages of your rainwater harvesting project and is designed to be used in conjunction with the above referenced guidelines. ❑ A permit is required for the installation of the rainwater harvesting system. No work shall be installed prior to issuance of the permit. Depending on the scope of work you may also be required to obtain building and electrical permits.(Section 7.1) ❑ You must submit a plan/diagram of the rainwater harvesting system along with the application for the permit.The plan/diagram shall include all portions of the system as required in Section 9.0. Please allow at least 5 working days for the review of the plans after which the permit may then be issued. (See also Sections 6.1 &6.2) ❑ Rainwater harvesting systems are a plumbing system and may only be installed by a Washington State certified journeyman plumber or by the property owner. The permit issued to a homeowner is an authorization for the homeowner to do the plumbing work or to receive assistance from a friend, neighbor, relative or other person provided that they are not being paid for their services. (See RCW 18.106.150) If a professional plumber is contracted with, they must be a registered contractor per Chapter 18.27 RCW and the installer must be a certified journeyman plumber per Chapter 18.106 RCW. You can verify on-line whether your contractor is registered and whether the installer is a certified plumber by going the Washington State Department of Labor & Industries website at httns:Hfortress.wa.gov/lnilbbii)/. Failure to comply with these state laws may result in additional fines and suspension of the permit. ❑ Harvested rainwater may only be used for water closets, urinals, hose bibs, industrial applications, domestic clothes washing, irrigation and water features. Other usages may be allowed when first approved by Public Health—Seattle&King County.(Section 6.6) ❑ Supply piping from the cistern to the fixtures/outlets must be installed and sized per the Plumbing Code. (Section 10.4) ❑ There are specific requirements regarding the labeling of the supply piping, the color of the label or piping, the spacing and the wording of such labels, and signs for equipment rooms. (Sections 10.5 & 10.6) ❑ All work must be tested in accordance with the plumbing code.The installation must be under test at the time of inspection by the plumbing inspector.No work shall be covered or concealed prior to inspection and approval by the plumbing inspector.(Sections 11.0& 12.0) ❑ The harvested rainwater shall be separated from the potable water by either an air gap or a reduced pressure backflow preventer(RPBA). A backflow preventer shall require;a separate permit and must be tested by a certified backflow assembly tester prior to inspection approval and annually thereafter.There may be additional backflow protection required by your water purveyor. Therefore, you should contact your water purveyor for additional information. ❑ Other types of water reuse systems, such as gray water and reclaimed water systems,require submittal of plans and diagrams prior to permit issuance and installation.Before you install any such system,contact the Plumbing Section of Public Health—Seattle&King County first. Some of these systems my require approval by other state or federal agencies. ❑ For further information regarding plumbing and backflow permits, inspections, office locations, contact phone numbers and other plumbing installation information, please visit our website at http://www.metrok-c.gov/health­/P--lumbiniz/. kjA ® King County General Department Department Policies and Procedures Policies & Procedures Title Document Code No. Product/Method#07-001 Rainwater Harvesting and Connection to Plumbing Fixtures REVISED: W01/2007 Department/issuing Agency Effective Date.

Page 10 of 10 og CODE GUIDE OFFICE OF PLANNING & DEVELOPMENT REVIEW TOPIC: Rainwater Harvesting — ICC — RES/34/#1 & UPC/6/#2 CODE: One & Two Family Dwelling Specialty Code: 2000 Edition; Plumbing Specialty Code: 2000 Edition APPROVED: March 13, 2001 REFERENCE: Section 3101.2 & Section 3401.1 — One & Two Family Dwelling Specialty Code Section 301.2 & Section 601.1 — Plumbing Specialty Code SUBJECT: Rainwater Harvesting Systems for Interior Use or Combined Interior and Exterior Use. QUESTION: 1. What is harvested rainwater? RESPONSE: 1. Harvested rainwater is untreated rainwater collected for limited use in specific plumbing systems. The rainwater may be collected in a variety of ways, and is then stored in a cistern for use on an as need basis. QUESTION: 2. Are there health concerns with using harvested rainwater? RESPONSE: 2. Yes. Harvested rainwater is not considered drinkable (potable) water. Therefore, it may not be used for any purpose other than irrigation, hose bibbs, water closets or urinals. Because harvested rainwater is not potable water it must be managed to protect both household occupants and the municipal water system from contamination. Proper cross connection protection, system maintenance and system marking are critical for the prevention of contamination to household occupants and the municipal water system. QUESTION: 3. Can harvested rainwater be used for drinking water? ICC — RES/34/#1 & UPC/6/#2 Rainwater Harvesting Systems for Interior Use or Combined Interior& Exterior Use Page 2 of 16 March 13, 2001 RESPONSE: 3. To use rainwater for potable purposes the water must be treated and meet State and Federal safe drinking water standards. Such systems are often complicated and expensive, and require continual maintenance, monitoring and testing. For this reason, the Office of Planning and Development Review (OPDR) will review and consider these types of systems through the administrative appeal process on a system by system basis. QUESTION: 4. What if I only use harvested rainwater for watering my lawn? RESPONSE: 4. When harvested rainwater is intended for irrigation only and the system is completely separate from the municipal water system and any plumbing in your structure, the system is not regulated by this guide. Although no plumbing permit is required, these systems still need to be approved by the Bureau of Environmental Services (BES) for stormwater management. In addition, other permits, such as an electrical permit for any pumps installed or a grading permit for underground pipe installation, may be necessary depending upon system size and complexity. QUESTION: 5. What are the parts of a rainwater harvesting system? RESPONSE: 5. A rainwater harvesting system begins at the point of collection and ends with the termination of the waste for the final fixture served. The parts of the collection and distribution system include: A. The Roof Surface. Rainwater harvesting systems rely on the collection of rainwater that has fallen on a building roof. B. Gutters and Downspouts. Gutters and downspouts are used to convey the rainwater from the roof surface to the roof washer and the cistern. C. A Roof Washer. The roof washer pre-treats rainwater before it enters the cistern. D. The Cistern. The cistern is the central portion of the rainwater harvesting system. Protection and maintenance of the cistern is essential for the health of the system. It is also extremely important that the cistern be sized adequately for the size of the household and the use of the water. E. A Pump. Often a pump is necessary to distribute the harvested rainwater from the cistern to the designated fixtures. F. The Piping System. The piping system conveys the harvested rainwater and distributes it to various fixtures. QUESTION: 6. Can rainwater harvesting systems be used in apartment houses, hotels, office buildings, retail stores, factories or other commercial buildings? RESPONSE: 6. Maybe. Commercial applications for rainwater harvesting are unique for each application. For this reason, each rainwater ICC — RES134/#1 & UPC/6/#2 Rainwater Harvesting Systems for Interior Use or Combined Interior& Exterior Use Page 3 of 16 March 13, 2001 harvesting system proposed for use in commercial structures must be engineered and site specific. In general, OPDR will consider, on a case by case basis, the following rainwater application in commercial buildings: A. Non-residential applications such as office buildings, factories or retail stores: water closets, urinal, irrigation or water feature usage. B. Residential applications such as multi-family apartment houses or the sleeping room portions of hotels: Irrigation only. QUESTION: 7. What are the definitions, requirements, installation standards and limitations for one or two family dwelling (home) rainwater harvesting systems with the City? RESPONSE: 7. The balance of this guide provides a basic rainwater harvesting system for use inside a home to provide water to water closets or urinals and combination systems using water both inside and outside a home for hose bibbs and irrigation. Rainwater harvesting systems that are designed using the standards outlined below do not need to be approved through the code alternate appeal process. A. General. All components of the system not specifically addressed by this guide shall meet all applicable code sections. 1. The requirements and allowances in this portion of the guide apply to one and two family dwellings only. 2. The rainwater harvesting system described below is based on a four- occupant home. 3. To ensure proper system installation, the code, this guide, and any applicable manufacturer's installation instructions must be followed. 4. Engineered systems shall be installed per plans and specifications of the engineer of record. 5. Harvested rainwater may only be used for water closets, urinals, hose bibbs and irrigation purposes. 6. Rainwater shall only be harvested from roof surfaces. Harvest shall not occur from the following locations: a. Any vehicular or pedestrian area; b. Surface water runoff; or C. Bodies of standing water. 7. The first 10 gallons generated by the rainwater harvesting system during any rain event shall be diverted away from the cistern. 8. Discharge of any diverted water shall go to a location approved by OPDR and BES. ICC—RES/34/#1 & UPC/6/#2 Rainwater Harvesting Systems for Interior Use or Combined Interior$ Exterior Use Page 4 of 16 March 13, 2001 B. Definitions.

Flat— having a slope no greater than 1 in 50. 4. Pump— mechanical device for moving fluids (rainwater). 5. Rainwater Harvesting System (RWS)—cistem(s) pipe, fittings, pumps and other appurtenances required for and used to harvest and distribute rainwater. 6. Return elbow—a section of pipe with a 180-degree bend. 7. Screen—corrosion resistant wire or other approved mesh having openings in determined sizes. 8. Slope or sloping—having a slope greater than 1 in 50. 9. Sun barriers—a structure erected specifically to shelter a cistern from the direct rays of the sun. 10. Reclaimed water—rainwater harvested for the purpose of supplying water to hose bibbs, water closets, urinals or irrigation. 11. Roof wash or roof washer—A device or method for removal of contaminants from collection surface by diverting initial rainfall from entry into the cistem(s). C. Permits. The following permits are necessary for the installation of a rainwater harvesting system: 1. A plumbing permit for rainwater harvesting systems. 2. An electrical permit for the pump or other electrical controls. 3. Building permits for cistern footings, foundations, enclosures and roof structures. Grading permits or erosion control may be necessary for underground tanks. D. Zoning Requirements. Rainwater harvesting systems must comply with applicable provisions of the Planning and Zoning Code (Title 33) including design review requirements. Rainwater harvesting cisterns and sun barriers will be reviewed as covered accessory structures under the provisions of Title 33. Base zone development, environmental zones, or design zones may affect or restrict cistern or sun barrier placement or design.

The symptoms ane:more congestion and air pollution resulting from our increased dependence on automobiles,the loss of precious open space,the need for costly improvements to roads and public services,the inequitable distribution of economic resources,and the loss of a sense of community. By drawing upon the best from the past and the present,we can plan communities that will more successfully serve the needs ofihose who live and work within thmi. Such planning should adhere to certain flmdamental principles. Community Principles: I 1. All planning should be in the form of complyte and integrated communities containing housing, shops,work places,schools,paras and civic facilities essential to the daily-life of the residents. 2. Community size should be designed so that housing,jobs;dally needs and other activities are within easy walking distance of each other. 3. As many activities as possible should be located within easy,walking distance of transit stops. 4. A community should contain a diversity of housing types to.enalile citizens from a wide range of eoonomic•levels and age groups to live within its boundaries.. 5. Businesses within the community should provide a range of job types for the community's residents. 6. The location and character of the community should be consistent with a larger transit network. 7. The community should have a center focus that combines commercial,civic.cultural and recreational uses. di. The community should contain an ample supply of specialized open space in the form of squares, greens and parks whose frequent use is encouraged through placement and design. 9. Public spaces should be designed to encourage the attention and presence of people at all hours of the day and night. 10. Hach community or duster of communities should have a well defined edge,such as agricultural greenbelts or wildlife corridors,permanently protected from development. 11. Streets,pedestrian paths and bike paths should contribute to a system of NY-conpented and interesting routes to all destinations. Their design should encourage pedestiian and bicycle use by being small and-spatially defined by buildings,trees and lighting;and by discouraging high speed treflro. 12 Wherever possible,the natural terrain,drainages and-vegetation of the community should be preserved with superior examples contained within parks or greenbelts. 13. The community design should help conserve rmurces and minimize waste. 14. Communities should provide for the efficient use of water through the use of natural dminage, drought tolerant landscaping and recycling. 15. The street orientation,the placement of buildings and the use of shading should contribute to the energy efficiency of the community. Regional Principles: 1. The regional land use planning structure should be integrated within a larger transportation network built around transit rather than freeways. 2. Regions should be bounded by and provide a continuoussystema of greenbelt/wildlife corridors to be determined by rmtuttal conditions. 3. . Regional institutions and cervices(government;stadiums.museums,etc.)should be located in the urban core. 4. Materials and methods of construction should be specific to the region,exhibiting continuity of history and coltore and compatibility with the climate to encourage the development of local character and community identity. lmplemsentation Strategy: 1. The general plan should be updated to incorporate the above principles. 2 Rather than allowing developer-initiated,piecemeal development, local governments should take charge of the planning process. Gannet plans should designate whom new growth.infill or redevelopment will be allowed to occur. 3. prior to any development,a specific plan should be prepared based on the planning principles. With the adoption of specific plans,complying projects could proceed with minimal delay. 4. Pians should be developed through an open process and participants in the process should be prbvided visual models of all planning proposals.

Fortunately titre are '- a number of stowards*actions that cities and counties can taloa that reduce costs and improve the reliability and quality of our water resources. The Water principles below complement*a Ahwalmee Principles for Resource- Efficient Communities that were developed in 1991. Many cities and counties arc already using them to improve the vitality and prosperity of their communities. community Principles 1. Community design should be compact,mixed use,walkable and transit-odetnted so that automobile-geneceted urban runoff pollutants are minimized and the open lands that absorb water are preserved to the maximum extent possible. (See the Ahwalnee Principles for Resource-Efficient Communities) 2. Natural resources such as wetlands,flood plains,recharge zones,riparian areas, open space,and nadve habitats should be identified,preserved and restored as valued assets for flood protection,water quality improvement,groundwater recharge,habitat,-and overall long-term water resource sustainability. 3. Water holding areas such as creek beds,recessed addedo fields,ponds,cisterna, and other features that serve to recharge groundwater.reduce runoff;improve water quality and deme flooding should be incorporated into the urban landscape. 4.. All aspects of landscaping from the selection of pmts to soil preparation and the installation of irrigation systems should be designed to reduce water demand, retain runoff,decrease flooding,and recharge groundwater. j S. Permeable surfaces should be used for hardscape. Impervious surfaces such as j driveways,streets,and parking lots should be minimized so that land is available to absorb storm water,reduce polluted urban runt recharge groundwater and reduce flooding. 6. Dual plumbing that allows grey water from showers,sinks and washers to be ireused for landscape irrigation should be included in the infrastructure of new developmerrt. 7. Community design should maximize the use of recycled water for appropriate applications including outdoor irrigation,toilet flushing,and commercial and industrial processes. Purple pipe should be installed In all new construction and remodeled buildings in anticipation of the future avallability of recycled water. B. Urban water conservation technologies.such as low-flow toilets,efficient cldthes washers,and more efficient water-using industrial equipment should be incorporated in all new construction and retrofitted in remodeled buiildings. 9. (around water treatment and brackish water desalination should be pursued when necessary to maximize locally available,drought roof water supplies. Implementation Principles I. Water supply agencies should be consulted early in the land use decision-making process regarding technology,demographics and growth projections. 2. City and county officials,the'watersbed council,LAFM,special districts and other stakeholders sharing watersheds should collaborate to take advantage of the beileflts and synergies of water resource planning at a watershed level. 3. The best,multi-benefit and integrated strategies and projects should be identified and implemented before less integrated proposals,unless urgency demands otherwise. 4. From start to finish,projects and programs should involve the publio,.build relationships,and increase the sharing of and access to hdb mation. The participatory process should focus on ensuring that all residents have mess to clean,reliable and affordable water for drinking and recreation. 5. Phnis,programs,projects and policies should be monitored and evaluated to determine if the expected insults are achieved and to improve future practices Authors: Celeste Cantu Martha Davis Jennifer Hosterman Susan Lion LongvUle Jonas Minton Mary Nichols l Virginia Porter Al Wanger Kevin Wolfe i Editor.

"Less costly treatment options can be used when water utilities start with higher quality source waters, and water supply reliability can simultaneously be enhanced." (Ca. Dept. of Water Resources,2005) Less mixing of higher and lower quality waters which facilitates "appropriately matching high quality source waters can reduce the levels of pollutants and pollutant precursors that cause health concerns in drinking water". (Ca. Dept. of Water Resources, 2005) Fire, earthquake—potential of electricity down and water supplies cut off due to electrical pumps being inoperative Drought—"Overall, the best positioning that SLO County could achieve with regard to planning for droughts is to develop multiple sources of water as opposed to relying on few sources to meet our water needs." (SLO County Water Resources, 2008 Externalities Environmental impacts of energy_costs (e.g. GHG emissions)_.

The California Performance Review(2004)cited a report by the Public Policy Institute of California estimating the state's'water supply and wastewater treatment systems maintenance backlog'to be about$40 billion. (California Department of Water Resources (John Andrew), 2004) 2 Research indicates that when considering climate change, RHSs may offer a more resilient urban water supply that is less susceptible to failure with"catchments exhibit(ing) a disproportionate decrease in yield in response to rainfall reductions, as compared to rainwater tanks...this may be, at least in part, due to the pervious nature of catchments that generally require significant re-wetting following reduced rainfall in order to generate appreciable runoff(whereas)..roof catchments are highly impervious and largely immune to the hysteresis exhibited by catchments in runoff generation ." (Coombes& Barry, 2007) 3"Water high in salinity can cause economic costs through damages to plumbing and fixtures and water-using devices and equipment. One study, conducted in 1998 by the U.S. Department of the Interior and the Metropolitan Water District(MWD), found that.forevery 100 mg/L decrease in salinity, there is an economic benefit of$95 million annually to MWD's customers" (Ca.
