Transcript of Building Outside the Box
-
Building Outside the BoxSustainable Building Practices for Water Quality and Quantity Working Approaches through EPA Targeted Watershed Initiative Grants
-
Cumberland River Basin
-
Whats special about our region?Outstanding recreational areas Globally significant biodiversity Most diverse mussel fauna1/2 freshwater fish in USMany threatened & endangered speciesBooming population growth
-
Major Challenges to Basin WaterGrowth and developmentUrban runoff, roads, & constructionIndustrial discharges Farming, clearcutting and loss of habitatAcid mine runoff, oil & gas drillingStraight piping and failing septic systemsInvasive exotic species
-
Urbanization impacts on water: Impervious surfacesLoss of buffer zones Flash floodsStream bank erosionLack of RechargeWater demandsWastewater dischargesUrban stormwater
-
How we got started in sustainable, water-friendly building: Held two Conservation & Common Sense Development WorkshopsPut Low Impact Development on the ground in the Cumberland Basin
-
Building Outside the Box was born to:
Demonstrate sustainable building practices Implement stream restoration projects Improve land use practices to protect water qualityEducate on benefits & methods of protecting water quality
-
Sustainable Building:Two Key Factors for Water Impervious Surface Cover mimic natural hydrologyStreamside Buffers mimic natural vegetation
-
Impervious Cover key factor1-10% IC = Sensitive 11-25% IC = Impacted26-100% IC = Non-supporting
Channel instabilityLoss of habitatPoor water qualityFlash Flood Drought Cycle

Improving the way we build: Start with good planning: TN Growth ReadinessCenter for Watershed ProtectionBetter Site Design Roundtable Codes & Ordinance Worksheet Training building professionals Training Realtors and Home Owners
-
Improving the way we build: Follow through with Good Implementation: TrainingIncentives Vigilance InspectionsEnforcement Focus on Erosion and Sediment Control
-
Multiple Levels of Awareness Required: Bankers to Brick-layers Growth & Zoning RulesUrban Planner DeveloperDesign EngineerArchitects BuilderContractorsSubcontractorsMunicipal officials Home buyer Real Estate agents Landscapers Erosion Control
BOB Educational Outreach:
EarthCraft House trainingsLID TrainingsHome Tours Design Charrettes Presentations LOC ProgramsSWAN website
-
BOB OutcomesDemonstrate sustainable building is cost effective and protects water quality Motivate building community to adopt it Raise awareness of public to ask for it Improve water quality in basin
-
Applications to Watershed Protection Cumulative effects make big differenceSmart sites to go with smart growth planningConservation design and erosion control are key components Can intervene at any point in process
-
Tangible Outcomes On the GroundFirst Earth Craft house in TennesseeFirst Water-Friendly mixed use development in NashvillePledges for over 1,000 water-friendly homesA fourth BOB site added with a fifth comingSOLD! Developers saw them sell and started building more!
-
Tangible Outcomes in EducationSoutheast Watershed Assistance Network launched and Over 1,000 people taught in person:-Builders learning on construction sites-Developers & Designers on site & in charettes and trainings-Professionals & the public attending workshops
