It~ is possible that this Ordinance will result in increased costs ~br certain capital improvement projects. The precise costs are unknown. Itis .e.s~.3~tg~O.~gLCity projects requiring LEEDTM silver certification under the proposed Ordinance could experience cost increases of up to 2% of the total project cost and an additional $20,000 to $40,000 for the LEEDTM application process. Another potential outcome might be a need to adjust Development Fees associated with Public Facilities to accommodate the estimated increase of 2%.

The proposed Ordinance contains 'the City Councils' recommended changes which was to incorporate the LEEDTM Silver rating, or a City-approved equivalent for all City building projects with the estimated cost of constrUction of' $3,000,000 or greater in value into the proposed Ordinance. GREEN BUILDING DESCRIPTION: Green building is a whole systems-apprOach to the design, construction and operation of buildings 2 fr°m the early stages of development (e.g. recycling C&D debris) through the final finishes of the building (e.g. using sustainable products). Conventional design and construction methods can produce buildings that negatively impact the environment as well as the health and productivity of the building occupants. These buildings can be expensive to operate and contribute to excessive resource and energy consumption, waste generation, and pollution. By contrast, green building provides a means for mitigating the undesirable environmental impacts of conventibn~i bfi{'~dihg methodS. This is acd0mpl~'~h~d' by~ ~mplo~ng bikiisiki~"rli~/te~a'is promote natUral resoUrce conservation, energy efficiency and good indoor air quality.

LEEDTM Silver dropped from 6% to 0..1% for small projects: and from 4% to none for large projects. While building to LEEDTM standards mays'result in addi~i0ng!_~gg for initial design and construction, LEED'm buildings are more economical than conventional b~.!dings (i.e.: non green) over thei~ lifetime. Energy and water efficient buildings can reduce operating.costs significantly. Use can be cut to less than half of a con~enti~naI bui!~g. Additionally, healthy indoor environments can increase employee productivity and reduce absenteeism. The State report foUnd that the 20-year Net'Preserit Value 0f the~!ifercYCle savings in energy, emissions, water, waste, and commissioning for a LEEDTM Certified or Silver Building averaged $15.98/sf, while the 20-year Net Present Value for improved productivity and health is $36.89/sf. The report concluded that a minimal upfi:ont investment of about 2% of construction costs typically yields life cycle savings of over ten times'the inifi~ investment. A [~nt.~.~ ~.~,.t~..~..w~.~:..~?~,~,~I supports ~he rep0rl's findings. .... Other Costs/Benefits In addition to potential project cost increases, other important green building considerations include the possibility of limited product availability and material selection and longer project completion schedules. The prO'duet market for green building materials, including recycled content products, while stiI1 somewhat' limited, has improved dramatically over the past several years. It is anticipated that the marker will continue to mature as more oi'ganizations adopt green building policies, resulting in even greater choices for green building products. It is also important to note that LEEDTM is flexible and allows for many options regarding which green building elements to incorporate in a given.project. LEEDTM is based on a point system, so if it becomes apparent that a specific product is unavailable, points could be earned by "greening" other areas of the project. Tree green building takes a holistic approach to a building and requires involvement from si~e planning and conceptual design through construction. If a project is identified as a green building fi:om the start, it is more likely that the project would be completed in the same amount of ti~ ~a~9~,pg~x~e~fi~p~l project. However, project delays can be more likely and more significant if the project is changed midway through design for example. Project components such as site o~entatigg, daylighting, Heating, Ventilations and Air Conditioning (HVAC), windows etc. are integral components to desi~ning an efficient building. If one of these elemen[s ~is changed, it could create the need for a major redesign because of how the components are interrelated. Green building will require more discussion and goal setting at budget development stage of the project in order minimize changes after the conceptual design has been approved. While not as easily measurable as the life cycle savings, other green building benefits should be considered includ~g environmental (conserving of energy, water and other natural resources; improving air and water quality and a reducing of solid waste) and community benefits (minimizing strain on local infrastructure, strengthening established goals related to increase density, mixed use and tra~.~.~it-9_~n~d~ development, improving stormwater and erosion covWol, increasing bicycle and pedestrian access and ('~ contributing to community health, vitality anii aesth'~ii~i}- KEY ELEMENTS OF THE PROPOSED ORDINANCE: ..........

AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF DUBLIN AMENDING TIlE MUNICIPAL CODE BY ADDING A NEW CI-IAPTER 5.61 MANDATING GREEN BUILDING ?RiCTICES FOR CITY PROJECTS The City Council of the City of Dublin does hereby ordain as follows: SECTION I: ENACTMENT The Municipal Code is hereby amended by adding Chapter 5.61, which shall read as follows: CHAPTER 5.61 GREEN BUILDING PRACTICES FOR CITY PROJECTS Section 1. FINDINGS The City Council of the City of Dublin hereby finds and declares that: A. The design, construction, maintenance, and demolition of buildings and structures within the City can have a significant impact on the City's environmental sustainability, resource usage and efficiency, waste management, and the health and productivity of residents, workers, and visitors. B. "Green" building design, construction, and operation can have a significant positive effect on energy and resource efficiency, waste and pollution generation, and the health and productivity of a building's occupants over the life of the building. C. Green building benefits are spread throughout the systems and features of the building. Building "green" can include, among other things, the use of certified sustainable wood products; aggressive use of high recycled content products; recycling of waste that occurs during deconstmction, demolition, and construction; enhancement of indoor air quahty by selection and use of construction materials that do not have chemical emissions that are toxic or irritating to building occupants; modification of heating, ventilation, and air-conditioning systems to provide energy efficiency and improved indoor air;. use of water conserving methods and equipment; and installation of alternative energy methods for supplemental energy production. D. The U.S. Green Building Council, developer of the Leadership in Energy and Environmental Design (LEEDTM) Commercial Green Building Rating System and LEEDTM Reference Guide, has become a leader in promoting and guiding green building. E. Requiring certain City projects to incorporate LEEDTM green building measures is necessary and appropriate to achieve the benefits of green building. ATTACHMENT F. Green design, construction, and operation decisions made by the City in the construction and remodeling of City buildings result in environmental benefits and cost savings to the City over the life of the buildings. By calling on the City to include green building measures in its own facilities, the City Council provides taxpayers a benefit through environmentally friendly, cheaper to operate buildings and simultaneously helps to develop markets for recycled, recyclable, and environmentally sound materials. G. It is critical to both the economic and environmental health of the City that the City provides leadership to both the private and Public sectors in the arena of energy efficiency and "green" construction. The most immediate and meaningfui way to do this is to include energy efficiency and green building elements in as many public buildings as feasible. H. It is in the public interest to address the appropriateness of mandating green building requirements for private projects separately from, and subsequent to, applying such requirements to City Projects. Accordingly, Unless and until the City Council determines 'otherwise, the provisions of this Chapter shall not apply to private sector development. Section 2. DEFINITIONS A. "Green Building Practices" means a whole-systems approach to the design, construction, and operation of Buildings and Structures that helps mitigate the environmental, economic, and social impacts of construction, demolition, and renovation. Green Building Practices such as those described in the LEEDTM Rating System, recognize the relationship between natural and built environments and seek to minimize the use of energy, water, and other natural resources and provide a healthy, productive environment. B. "Building" means any Structure used or intended for supporting or sheltering any use or occupancy as defined in the Dublin Building Code. C. "Structure" means that which is built or constructed, an edifice or building of any kind or any piece of work artificially built or composed of parts joined together in some definite manner and permanently attached to the ground. D. "City Project" or "Project" means new Construction or Renovation primarily funded or sponsored by the City, conducted on City-owned property, or managed by City personnel from design through construction. "City ProjeCt'' or "Project" shall also include any Buildings constrUcted for the City's use under a build-to-suit program or project. Traditional Public Works Projects and Parks Projects are not considered "City Projects" for the purpose of this Chapter. E. "Construction" means the building of any Building or Structure or any portion thereof. F. "Renovation" means: (1) a structural change to the foundation, roof, floor, or exterior of load-beating wails of a facility, or the extension of an existing facility to increase its floor area; or (2) alteration of an existing facility, such as to sigrdficantly change its function, even if such renovation does not include any structural change to the facility. G. "Initiated" means officially identified and fully funded to offset all the costs associated with the project as found on the City Capital Improvement Plan. H. "Conditioned Space" means an enclosed space in a building that is provided with a mechanical heating/cooling system as defined in the Dublin Building Code. I. "Estimated Cost of Construction" means the total projected cost of completing a proposed Project, .including fees, design, construction and land. J. "LEED Accredited Professionalm'' means an experienced building industry practitioner who has demonstrated his/her knowledge of integrated design and his/her capacity to facilitate the LEEDTM certification process on the LEEDTM Professional Accreditation exam. The exam, administered by the U.S. Green Building Council, tests an individual's understanding of green building practices and principles, and familiarity with LEEDTM requirements, resources, and processes. K. "LEED Rating Systemm'' means the most recent version of the Leadership in Energy and Environmental Design (LEED?~ Commercial Green Building Rating SystemTM, or other related LEEDTM Rating System, approved by the U.S. Green Building Council, as applicable to the Project.

FINANCIAL STATEMENT: It is possible that this Ordinance will .result in increased c~sts, for certain capital impzovement projects. The precise costs are unknown and will partially depend ion the desired level of certification selected by the City Council. It is estimated that City projects re.quiring LEEDTM silver certification under the proposed Ordinance could experience cost increases of up to12% of the total project cost and an additional $20,000 to $40,000 for the LEEDTM application process. A~nother potential outcome might be a need to adjust Development Fees associated with Public Facilities to. accommodate the estimated increase of 2%..However, green buildings typically result in signific~mt life cycle savings, often exceeding the initial investment by as much as ten times. DESCRIPTION: As part of its 2003-200g Goals and ObjecUves, the City Council directed Staffto prepare a green b~.Idmg ordinance. This report provides a description and analysis of green building as well as a comprehe~ive account of the development and key components of the City's proposed green building Ordinance. COPIES TO: ATTACHMENT 2 lt/cc-forms/agdasLmt, doc GREEN BUILDING DESCRIPTION: Green building is a whole systems approach to the design, Construction and operation of buildings -~rom the early stages of development (e.g. recycling C&D debris) through the final finishes of the build/n~ ('e.g. using sustainable products). Conventional design and construction methods can produce buildings that negatively impact the environment as well as the health and productivity of the building occupants. These buildings can be expensive to operate and contribute to excessive resource and energy consumption, waste generation,, and pollution. 'By contrast, green building provides a means for mitigating the undesirable environmental impacts oil conventional building methods. This is accomPlished by employing building materials and method~; that promote natural resource conservation, energy efficiency and good indoor air quality. Although sustainability is a global issue, building plans are approved and constructed locally, and it is at this level that cities may have the greatest impact. The adoption of the proposed Green Building Ordinance will formalize the City of Dublin's green building practiceS.and ~efme a .process for, construction and op~ation of certain city buildings. In addition, adop.tion of the Or.

U.S. Green Building Council and LEEDTM ' The United States Green Building Council (USGBC) is a national nonprofit organization that was rearmed /,~..in 1993. Its growing membership includes representation from orgamzations acro. ss the b. mldin,g in.~ ,ustry, including architecture and engineering firms, bmtders, manufacturers, government agenmes, rem estate developers, universities, and others. USGBC develops industry standards, design practices and greeh building education. It is the developer and admlni~qtrator of the Leadership in Energy and Environmental Design (LEEDT~ Green Building Rating System. A;~escription of the LEEDTM rating system is included in the article LEED: Good for Business, Good for the Environment (Attachment 1). The complete LEEDTM rating system is aisc included as Attachment 2. LEEDTM was developed to define "green building" by providing a standard for measurement. The LEEDTM Rating System dc£mes "green building" as a building that is designed to minimize envirorr~ental' impacts in the following ways: 1. Sustainable.Sites - i.e. building with access to mass tr_amit and reducing stormwater mn~off 2. Water Efficiency - i.e. water efficient landscaping 3. Energy and Atmosphere - i.e. reducing energy consumption in the buildings 42 Materials and Resources - i.e. designing for the storage and collection ofrecyclables and construction and d~notifion waste management 5. Indoor Environmental Quality- i.e. reducing the quantity of indoor air contaminants, such as Volatile Organic Compounds (VOC), and increasing daylighting in the buildings LEEDTM uses existing, proven technolo~es to guide commercial, public and institutional buildings. ! It is now the most widely used green building rating system nationally. Many jurisdictions including Alameda County, Berkeley, Pleasauton, San Jose, San Francisco, San Marco County, Santa Monied, Portlanc[ and f"~. Seattle have developed their green building.programs using LEEDTM as a standard or guide. Several projects in Alameda County, including: the Alameda County Hail of Justice and the Alame~, County Juvenile Detention'Cenler, Pleasanton Fire Station, Berkeley Fire Station, and two Universit~ of California Studc~nt Housing projects, are being designed using LEEDTM as a standard. LEEDTM is performance-based, with four levels of certification (Cert/fied, Silver, Gold and Platinum). Certification is solely performed by USGBC. [ COSTS AND BENEFITS OF GREEN BUILDING: Fiscal Impact The State of California recently released the most comprehensive analysis of the financial costs and benefits of green building titled The Costs and Benefits of Green Building (October 2003) (Attachm, ~nt 3). The study reported that the average add/tional cost for substantial green building design was slightl . less than 2% (of the building's total design and construction cost), which translates to approximately $3-'5/sf. This conclusion was made after a survey of 33 LEEDTM buildings. The majority of the additional cc st is attributed to the increased architectural and engineering design time necessary to integrate sustainable building methods into projects. The earlier green building gets incorporated into the design process, the lower the cost. Addressing each of these factors can minimize additional capital costs: Identify projects to be LEEDTM certified at the establishment of thc project budget Include LEEDTM requirements in RFQs and KFPs Use LEEDTM early in the design process · TraS~ project managers in LEEDTM managemgnt skills. · It is important to point out that the cost of green buildings will vary significantly depgnding on the specific project goals. While there are many significant benefits that can be included in a. project at no additional cost (orientation, low VOC paints, recycled content carpet, etc.), some features will cost more. Estimates for additional initial costs are as low as 0 to 2%...A'LEEDTM Study conducted for the City of Portland indicated that green building impact on the budget is small - from 2.2% extra cost to 0.3% savings. The City of Seattle found that after a 3-year implementation period, the incremental cost for meeting LE~.DTM Silver dropped from 6% to 0.I% for small projects and from 4% to none for large projects! (Attachment 4). While building to LEEDTM standards may result in additional funding for initial design and constru0tion, LEEDTM buildings are more economical than conventional buildings (i.e.: non green) over their lifetime. Energy and water efficient buildings can reduce operating costs significantly. Use can be cut to lessi than half of a conventional buildSng. Additionally, healthy indoor environments can increase employee productivity and reduce absenteeism. The State report found that the 20-year Net Present Value oft. he life-cycle savings in energy, emissi ns, water, waste, and commissioning for a LEEDTM Certified or Silver Building averaged $15.98/sf, while the 20-year Net Present Value for improved productivity and health is $36.89/s£. . . The report concluded that a minimal upfront investment of about 2% of consU'ucfion costs typ~callylsaelds life cyete savings o£over ten times the initial investment. A recent article in the Wall Street Journal supports the report's findings (Attachment 5). Other Costs/Benefits~ ~ ' In addition to potential Project cost increases, other important green building considerations inclu~de the possibility of limited product availabilit~ and material selection.and longer project comPletion sched~utes. The product mm:ket for green building materials, inClUding recycled con~ent Products, whi still ~somewhat limited, has improved dramatically over the past several years. It is anticipated that the market Will continue to mature as more org.a?zations, adopt green bull _diin. g poli¢iers~s, resulting in even ;renter choices for green building products. It as also nnportant to note that LEED is fleXible and alia ~,s for many options regard/ng which green building elements to incorporate in a given project. LEEDTM i,, based on a point system, so if it becomes apparent that a specific product is unavailable, po/nts could be earned by"greening~' other areas of the project. Tme green building takes a holisfic approach to a building and requires involvement from site pl tuning and eoneeptuaI design through construction.

Green building will require more discussion and goal setting at budget development stage of the project in order minimize changes after the conceptual design has been. approved. While not'as easily measurable as the life cycle savings, other green building benefits sholdd be considered including envir~mentai (conserving of energy, water and other natural .resources; improving ak and"water quality and a reducing of solid waste) and commuu~ty benefits (minimizing strain o¢'local infrastmcUtre, strengthening established goals' related to increase density, mixed use and transit-o~ented f~: development, improving stormwater and erosion control; increasing bicycle and pedestrian acce? and ~" contributing to Community health, vitality and aesthetics). ACCOMPLISI:I/VIENTS AND PROCESS: ' The following section Provides a briefhistory'0fthe City's efforts related to green building includin, the steps leading to the development of the proposed green building Ordinance. ConstrUction and Demolition Ordinance On February 15, 2000, the Dublin City Council adoPted a Construction and Demolition Ordina~, the first of its kind .in Alameda County, which was based on a model developed by the Alameda :County Waste Management Authority (ACWMA). The purpose of the Ordinance is to require maximum t~as~le recycling at new construction sites, and salvage, and deconstrucdon for remodel/rig and dem,'olition projects. . e The city, s ordinance has been used as a model for other jurisdictions throughout the State and islon of the few that includes.a .performance security requirement. The Orrtinance has been ex'~a-. ~ ~m~.ely successful and has had a dramatic impact on the City'S diversion' rate. In 1999, the City had a diversion rate C f 33%. Thanks in large part to the success of the Ordinance; the City's diversion rate for 2001 .was 50%. Fire Stations 17 and 18 Construction Grant Award. for Utilizing Green'Bttilding Practices "The City of Dublin Was awarded '$10O,000 by the' ACWMA that was equally divided for the c°nstn~ otion of the two fire stations to incorporate green building materials and practices. Senior Housing Grant Award .~ . Ir(.,)_ ~.,~ ~.~. The City of Dablin and Bden Housing, the developer of the City of Dublin's Affordable ~emor l-lou$~ng project, were selected through a competitive process to participate in the Multi-Family Affordable Housing Green Building Design Assistance Program from ACWMA. A $5,000 grant was awarded~o help subsidize Eden Housing's participation in the development of Multi-Family Green Building Guidelines. City of Dublin's Housing Element Included in the City's State-approved Housing Element of the General Plan is a policy on the promo~on of energy efficiency in new projects. The elements that support this policy are: Continue to implement the City's Construction and Demolition Recycling Ordinancei Continue to provide on-site training for' City Building and Planning Staff on '13uilding techniques. ContinUe to review proposed developments for solar access, site design techniques, and use of landscaping that can increase energy efficiency and reduce lifetime energy costs .without significantly increasing housing productions costs. - Provide access to infomation on energy conservation and financial incentives (tax icredit, utihty rebates, etc.) through public information to be provided at the City's public cbunter, on the City's Web site, at public libraries and community centers. Training and EducationaI Opportunities - · ..The City, in cooperation with the'ACWMA, has coordinated several green building workshops to e~:lucate Staff and developers on Green Building practices. The workshops have included a recent Tri-¥alley Builders workshop on Green Building Initiatives and a Tri-Valley Building Inspectors Workshop on inspecting Green Points. Additionally, several Stuff members have attended the LEEDTM t~aining program. Green Building [Fork Group The process of developing a green building ordinance began with the formation of a green building work group comprised of Staff members fi:om Community. Development, Public Works, Parks and Commuuity Services, and the City Manager's Office as well as Staff and consultants from the ACWiViA. Th{ group began by reviewing several green building ordinances fi:om Bay area jurisdictions including the 2ity of Pleasanton and Alameda County and the ACWMA Civic Green Building Model Ordinance. A matrix comparing the various ordinances is included as Attachment.6. . PROPOSED CIVIC GREEN BUILDING ORDINANCE: · 8taffhas developed an Ordinance (Attachment 7)that defines and sets thresholds for ine0rporating ~reen building practices in civic projects. The key elements of Dublin's proposed Civic Green Building Ordinance are as follows: The OrdinanCe only covers city sponsored proj cots, defined as any new construction or rent,ration primarily funded or sponsored by the City, conducted on City-owned property, or managed 1Jy citY personnel fi:om design through consWaction. "CitY Project" or '*Project" shall also include any Buildings constructed for the City's use under a build-to-suit program or project. · An city bundins rrojects wit the' °ns etion of S3,000,O00 or geat r iq shall be desired to meet a desisted ~m~ LEEDx~ rang ~ specified ~n ~e Or~n~ce, or a C~W-approved eq~valent.

Building types. · The work group quickly realized that there were two separate elements of a green building program: civic buildings and private development. The work group concluded that it should first focus on developing au ordinance that would apply to civic buildings such as upcoming Em~d Glen Park Recreation Center. Once completed, the City could investigate options for private development. One of the most eomi~elling reasons for developing au ordinance limited to civic buildings, was the idea that the City should "lead by example." If the City is ever to' require developers ';o incorporate green building practices ig their developments, the work group felt thru it was important that the City first impose a similar, if not more aggressive requirement on itself. Additionally, the ACWMA Model Ordinance was developed for civic buildings and it was agreed that the model Ordinance would be used as a starting point for developing the City's Ordinance. The ACWM. A also.has a design assistance and grant program in place to assist member agencies in implementin green building practices and incorporating sustainable products into public facilities. ZEED ~r~ Certification Rating The proposed Ordinance is based on LEEDT~ because Staff believes the natig.nally recognized L]~,ED rating system to be the most comprehensive rating system available and it is the standard used other jurisdictions in the Bay Area. The proposed Ordinance includes three options for the Council to c~nsider regarding the level of LEED~ certification that wilt be required for City projects. . LEED'n'¢ is a design rating system with 69 possible points. For'classification as a LEEDa'~ bdigldin, buildings must satisfy seven prerequisites and a minimum number of points for the desired. l~vel of certification. Four levels of green building certification are awarded based on the total number }credits earned in each of six categories: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Mhterials and Resources, Indoor Environmental Quality and Innovation and Design Process. To achieve a "Certified" rating, projects must meet all of the prerequisites and earn a minimum of 26 point5,!with a minimum of 33 required for "Silver'', 39 for "gold" and 52 for "platinum". 'Thc comparison of ordinances, matrix indicat~ ~e requirements £or various jurisdictions. jUrisdictions require'either a certified or silver rating. Staff believes that a certified rating coflld be achieved with a few modifications to existing, procedures such as. hii/ng': an architect that is LEEDTM certified. Several of the citY;S recent projects, while not measured or certified.using the LEEDTM standard, would most likely have come close to achieving a certified rating. In order to ach/eve, a silver rating, more effort would need to be devoted tothe project during the ~esign phase and more green building elements would need to be included. Many of the points/n thel rating system can be earned at little or no cost. However the more points that are required, the more lik~ty that the green building components esso/isled with the those..incremental points will add to the cost i of the project. It is impossible to predict .the exact fiscal impact of achieving a certain LEEDTM rating, hqwever studies cited previously ~ the Staff report indicate that a silver rating ~ould be achieved with less ithan a 2% cost increase. The proposed Ordinance includes three LBEDTM certification, options for the Council to eohsider: Certified; SilX~er; or minimum certified and strive for silver. Staff requests direction from th.e £ ouncfl regarding the desired IeveI of certification required for City projects. Threshold The LEEDTM rating' system was developed and is intended for large new. construction and major renovation projecm. With this Understanding, Staff completed a thorough analysis of the City's Capital Improvement Program in order to determine the minimum threshold that shouk!, be .met in order to/:equire LEEDTM certification. Staff wauted to establish a threshold that would capture all of the major City projects that would be appropriate to require a LEEDTM certification- The analysis revealed that a threshold of $3 million would accomplish this goal. The proposed Ordinance states that al1 City projects with the estimated cost of construction of $3 million or greater in value shall be designed to meet a designate6 minimum LEEDTM rating. The current projects that would require LI~.EDTM certificafior[ under the proposed Ordinance include the following: o Emerald Glen Park Aquatic Center Emerald Glen Park Recreation Center Emerald Glen Park Community Center · Community Theater There are many City projects with an estimated construction cost of less than $3 million, however none would be appropriate for T,I~.EDTM certification due to the nature and size of the projects. Addi~onally, there are many park and street projects that are over certification under the proposed Ordinance because they do not fit in the Ordinance's defin/fion of construction and would not be appropriate for LEEDTM. Operational Green Building Practice Guidelines All City proj eels not. required to achieve LEEDTM certification, whether due to the value threshold o~r the nature of the project will be required to incorporate Green Building Practices in the project. Upon adoption of the Ordinance, Staffwill work to develop an Operational Green Bu/lding Practice Guid,qines that will specify appropriate green building practices for all City projects that do not qualify for LEI ~DTM certification. Additionally, The Operational Green Building Pra~tte:~ Gi~delincs wi11 include important lmpleme~ataUon assistance for Staff regarding items such as the development of criteria to escalate or lower the $3 rhillion dollar threshold, appropriate language~ for projects specifications and request for qualifications, and how the Green Building Compliance Official will administer and monitor compliance with the Ordinance. The Ordinance requires the Guidelines to be developed within twelve months of adoption of the Ordinance. NEXT STEPS Once the work related to civic projects is completed, the recommended next steps if the Council des[res - have the Green Building Program to be expanded to included private development it should identifyl this au item for consideration during.the upcoming Goals and Objectives Process. m COMM A O : [ Staff recommends that- the City Council review the proposed Ordinance and attached docments ents to Staffwith s ecific directions regarding the' desired level o£LEEDTM eertificatibn.
