  • 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

  • Building Outside the Box (BOB) Demonstration sites in three impaired watersheds of Cumberland Basin***Suburban Harpeth RiverUrban Mill CreekRural Red River

  • EarthCraft at Quiet Creek

  • Rain Gardens = Greater RechargeGreater BeautyLess stormwaterWin, win

  • Morgan Park Place Nashville Two blocks in Germantown historic district 63 units mixed useModel Urban Stormwater treatmentEarthCraft Multi-family Certified Lawrence Brothers and New Urban Construction

  • New technologies are versatile and protect water from the inside and the outside With tankless water heaters pervious surfaces and more!

  • Harpeth River BOB suburban site620 acre farm site in Franklin, TNOn Harpeth mainstem 1000 homes planned Aggressive LID practicesAll high performance homesOver 40% open space

  • Highlands at Ladd ParkHarpeth River BOB Site

  • Stream Restoration all 3 sites Focus on tributaries and headwaters Establish and protect buffer zones Vegetative plantingsStream bank stabilizationDisconnect stormwater runoff

  • Project Monitoring In-Stream baseflow water quality In-stream storm event samplingSite runoff on Quiet Creek site Economic costs and savingsDevelopers and buildersHome ownersCommunities

  • BOB Site Goals Less impervious surfaceMaximum green spaceMaximum stream buffersRunoff infiltration Native vegetation Water conservation Energy efficiency

  • Better Site Design FeaturesCluster housing Narrow roads/sidewalksRain Gardens/BarrelsPervious concrete Dual track or shared drivewaysInfiltration landscapingWater saving appliances

  • Infiltration landscaping

    Open Section Roads

    Grass Channels and Swales

    Infiltration Trenches

  • Roof runoff infiltration

  • BOB Home ConstructionEarth Craft certified home construction Systems approach to sustainable buildingEnergy efficiencyWater efficiency Green materialsIndoor air quality

  • Benefits of High Performance House BuildersHigher demand & market share Higher profits Higher quality product with lower costsLower liability risks Lower call backs Homeowners Higher home valueUtility SavingsBetter Indoor Air QualityHealth Benefits Greater durability & value appreciation

  • 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
