In addition to the three private stakeholder meetings, Cascadia also presented the SARD project attheVancouverPlanningCommission’sFirstTuesdayeventinMarch2009andattendedapublicopen house, also in March 2009, to further communicate the project’s goals and findings.

inteRnal stakeholdeR meetings

A meeting with the City and County building officials was held to review the building code barriers matrixandbrainstormonstrategiesforremovingobstacleswithintheInternationalBuilding,MechanicalandFireCodesandwithintheWashingtonStateEnergyCodes.

Due to the inter-agency nature of the barriers arising around projects seeking net zero water goals, a separate meeting was held specifically to discuss the draft water barriers diagram.

Background

Throughouttheexternalstakeholderworkshops,aresoundingthemefromparticipantswasthedesireforamorecollaborative,consistent,andopenprocessforseekingregulatoryapprovalfor sustainable, affordable, residential development projects. Green projects typically have to justify design approaches over again for each project because there is a lack of consistency or communicationamongreviewersandinspectorsonapprovedalternatives,requiringasometimeslengthyandexpensivepermittingprocessforapplicants.

short term Recommendations

1. Establish an Expedited or Priority Permit Processing Program for Green Projects.

Because green building projects, especially those that are proposing new technologies or alternativematerialsormethodsfromthoseprescribedincodes,canrequirelongertimeforreview and approvals, guaranteeing a shorter review schedule or placing these projects at the frontofthereviewlineisonewaytohelpfacilitateasmootherprocessforapplicants.Whiletheexternalstakeholdergrouprecommendedthedevelopmentofaprocessforqualifyingan“A-list”ofdesigners,builders,etc.tohelpstreamlineapprovals,thisapproachisnotrecommendedforavarietyofreasonsprimarily because building officials are responsible for ensuring that each project meets public health and safety standards. Instead, providing expedited or priority review for projects (rather than individuals) demonstrating a commitment

Page 12: SARD Report2_Final_4.17.09_web

�0 Report#2,Strategies&Recommendations: CodeBarriersforSustainable,Affordable,ResidentialDevelopment

�7April2009

to reaching a high level of green building design (e.g. LEED-Gold certification) would ensure theintegrityofsuchaprogram.Additionally,manybuildingdepartmentshaveinstitutedapriority or expedited permitting program for green projects that is integrated within their existing review process and therefore does not require extensive staffing or resources to manage.

2. DevelopIn-HouseMandatoryTrainingsTargetedtoPlanners,PlansExaminers,BuildingOfficials, and Inspectors.

Asnewgreenbuildingtechnologiesandsystemsareintroducedintothemarket,theimportanceofongoingtrainingforplanningandbuildingdepartmentstaffisespeciallycriticaltohelpaddressinstitutionalandprocessbarriers.Theexternalstakeholdergroupindicatedthatconsistencyamongstreviewersorinspectorswhoarechargedwithapprovalsthroughoutthe life of the project is lacking. Feedback from the City and County building departments indicated that while a single plans reviewer or inspector throughout the project’s approval process is ideal, this is not always feasible based on resource or staffing issues. Trainings combined with monthly or quarterly meetings between building officials, plans examiners, and inspectorstolearnaboutnewtechnologiesandcoordinatecommunicationongreenbuildingprojects is one way to help address this obstacle. Bringing in experts from the private sector and utilizing in-house experts to teach trainings, as well as taking field trips to see sustainable developmentstrategiesin-placearealleffectivewaystohosttrainingsonalimitedbudget.

long term Recommendations

3. Establish Mandatory Green “Pre-Application” Meetings to Involve Building Officials and ReviewersEarlyonintheDesignProcess.

A key component to a successful green project, and particularly important for projects seeking tomeettheLivingBuildingChallenge,istheutilizationoftheintegrateddesignprocessamongst project teams. As described in Report #1,thetraditionallylinearnatureoftheapprovals process can create barriers for integrated design projects, which inherently rely onaniterativeinformationcycle.Onehighpriorityfortheexternalstakeholdergroupwastoreplacethe“turnin,getfeedback,turninagain,getfeedback”reviewapproachwithmorecollaborative face-to-face opportunities. This allows project teams to meet with those who willberesponsibleforreviewingandapprovingtheirplansandhaveconstructivedialoguesaround opportunities and challenges while the project is still in the early stages of design. Early design meetings with building officials and reviewers may be free-of-charge to applicants as an incentive to encourage more sustainable development projects, or they may be an added cost to the project team. If the latter is implemented, education and communication around involving building and public health officials early on to help create a smoother and quicker overallreviewprocesswillbeimportantsothattheperceptionofincreasedfeesdoesnotdiscourage green projects. Assigning the green project an ombudsman or “green champion”

4. CreateaGreenBuildingTechnicalAssistanceProgram.

A green building technical assistance program would serve two purposes: first to support educationandoutreachinternallyaswellasincreasethecollaborationbetweendifferentdepartments;andsecondtoprovidetheprivatedevelopmentcommunitywithanestablishedstarting point for tackling code obstacles for green projects. The external stakeholder group expressed a desire to shift the mindset of the jurisdictions to be more positive and open to newideas.Knowingthattheyhaveapointofcontactforbringingforwardnewandinnovativesustainabledevelopmentdesignstrategiesisonewaytoaddressthisshiftinmindset.

To leverage resources, a cross-jurisdictional technical assistance program between Vancouver andClarkCountyandpossiblyincludingothercities/townswithintheCountycouldbeestablished. Many jurisdictions have found resources to establish green building technical assistanceprogramsthatdovetailwithalreadyestablishedconservationprogramsfundedbylocalutilities,forexample,throughsolidwaste,drinkingwater,stormwater,wastewater,orenergyutilityconservationfees.

short term Recommendations

1. Define Requirements and Develop Guidelines for Permitting Renewable Energy and Passive Heating/CoolingSystems.

Theobstaclesaroundrenewableenergysystemsandpassiveheating/coolingdesignstrategiescurrently acceptable by codes stem from either the absence of defined standards, or from the real or perceived obstacles that project teams may encounter during the regulatory process. Thedevelopmentofcodeguidelinesaddressesboththeissues.

Looking to wind ordinances developed by other jurisdictions, it is recommended that Vancouver and Clark County define standards for permitting both urban and rural small scale wind energysystemsincludingsetback,heightandnoiserequirements,aswellasstructuralrequirementsforbuilding-mountedinstallations.Similarcodeguidanceforphotovoltaicandsolar thermal installations should be developed. Lastly, guidelines for project teams wanting toutilizepassiveheating/coolingdesignstrategieswillhelpcommunicatewhatisallowedby code. Guidelines should specifically address optimizing solar orientation, balanced with theimportanceofshadeandtreeretentiononsite.AreviewofClarkCounty’sformersolarordinancecouldserveasalaunchingpointfornewpolicydevelopment.

2. Consider Density Bonuses for Energy Efficiency Measures.

WhileClarkPublicUtilitiesdoesofferrebatesforenergyconservationmeasures,additionalincentiveswithintheauthorityofCityandCountybuildingandplanningdepartmentsmayhelp offset the added costs for incorporating aggressive efficiency measures and renewables, especially for affordable housing projects. Offering density bonuses in strategic zoning areas suchasdowntownorneighborhoodbusinessdistrictsinexchangeforhighperformanceenergy efficient buildings is one suggestion. Utilizing increases in floor area ratios (FAR), instead of straight height restrictions, allows for flexibility in the building design. Where density bonusesalreadyexistforaffordablehousing,combiningbonusesassistsaffordablehousingprojects by offsetting the initial costs of design or construction for efficiency measures or renewables with additional financing or revenue from added housing units.

InlessdensesuburbanandruralareasoftheCityandCounty,developingprovisionsfor cottage housing can help encourage smaller, more energy efficient homes. See recommendations under Cluster Development/Cottage Housing.

short term Recommendations

1. Allow Flexibility for “Incubator” Pilot Projects to Test Alternative Green Materials.

Collaborate with pilot projects to test alternative green materials, specifically those becoming moreandmorecommonlikestrawbalethatarestillrequiredtoutilizethealternativecodecompliancepaths,inordertoestablishstandardsandguidelinesforfuturecodechanges.It is important to disseminate findings from pilot projects both internally within the building departmentaswellastothedevelopmentcommunitysothattheybecomeresourcesforfuture projects. The Development Center for Appropriate Technology (www.dcat.net)hasanestablishedCodeComplianceinformationpackageforalternativematerials,systemsanddesigns that could be used as a template for standardizing the procedure for pilot project applicants.

2. DevelopCodeGuidanceforStrawbaleStructures.

Many jurisdictions have developed strawbale codes including Tucson/Pima County, AZ; Boulder,CO;Easton,PA;Austin,TX;GrandCounty,UT;andthestatesofCaliforniaandOregonwherestrawbalestructuresareincludedintheOregonStateResidentialCode.InWashingtonState, strawbale has been approved in multiple cities and counties by local jurisdictions throughalternativecodeprocess,includingoneapplicationwithinClarkCounty.TheCityandCountyshoulddevelopformalcodeguidanceforstrawbalestructuresthatcanbeusedasaresourcefordevelopers.

long term Recommendation

�. DevelopNewCityandCountyCottageHousingCodes.

Cottagehousingcodeslimitthesizeofunits,typicallytonomorethan�,000squarefeetinsize, allowing developers to increase the density on a parcel. Many jurisdictions in Washington State have developed cottage codes or allowed for cottage-style demonstration projects to helpestablishnewstandards.TheCityandCountyshouldutilizealready-establishedcodesfrom other jurisdictions to develop new cottage housing provisions, allowing for demonstration projects that help define standards in the interim.

Cascadia’s next steps as part of the SARD project will be to:

Work collaboratively with the City and County to evaluate costs and benefits of the prioritized recommendations,bothinternallytothepublicagenciesaswellasexternallytotheprivatedevelopmentcommunity.

Utilize the two residential project types studied under Cascadia’s Financial Study for the Living Building Challenge as the starting point for the cost/benefit analysis, modifying the Portland prototype projects to reflect Vancouver and Clark County construction costs and incentives.

A final report on the cost/benefits analysis will be delivered to Vancouver and Clark County in June2009.
