Water Too Much or Too Little? Or a Little of Both? URS Group Inc ASFPM National Conference May 2010
Presentation Title Flooding vs droughts Data on water usage and the problems associated with it.
Presentation Title Ground-truthing green What is Green Infrastructure? What are the types that should be considered for large scale reduction of storm water? How can it benefit floodplain, stormwater and wet weather management? How are communities already using it and quantifying its use?
Presentation Title Green infrastructure Natural and managed green areas in both urban and rural settings, Strategic connection of open green areas, Treating rainwater as a resource and not as trash to be discarded as quickly as possible, Transforming “grey” infrastructure to green through restoration of watersheds to slow and store water, and Providing multiple benefits for people. Green infrastructure is management approaches and technologies that utilize, enhance and/or mimic the natural hydrologic cycle processes of infiltration, evapotranspiration and reuse. Wet Weather Action Strategy 2008
Presentation Title What else is green infrastructure? Helping communities come closer to attaining the CWA standards Public Perception (sustainable cities) Leverage State and Federal Program Dollars Opportunity to “marry” multiple public work efforts (street scaping, sidewalks, parks, floodplain & stormwater management)
How much does an individual home affect stormwater runoff? Street Driveway House Stormdrain
Presentation Title How much does an individual home affect stormwater runoff? Street In a 1” rainfall Potential Runoff: 5,422 gallons 2,500 s.f. “impervious” x 1” rain = 1,542 gallons of runoff Stormdrain 1,500 s.f. house (& patio) x 1” rain = 925 gallons of runoff + “Green Concrete” Compacted Lawn 8,390 s.f. “impervious” x 1” rain (if infiltrates first ¼” of rain) = 3,880 gallons of runoff 1,000 s.f. driveway x 1” rain = 617 gallons of runoff
Presentation Title Where can rain (stormwater) soak in?
Presentation Title Q – How do we protect our streams and infrastructure? A – Manage How Stormwater Runs Off the Landscape
Presentation Title Distributing stormwater controls close to runoff sources Distributed Stormwater Features Regional Traditional Techniques
Presentation Title What does green infrastructure look like? Stream Buffers Green Space Preservation Trees Rain barrels Wetlands (preserve and restore) Regional Planning NAI Best Management Practices
Presentation Title Alternative Designs
Presentation Title Constructed Wetlands
Presentation Title Other Applications
Presentation Title Green Roof Applications
Presentation Title Pervious Infrastructure
Presentation Title Rain Gardens & Bio-Infiltration Devices
Presentation Title These characteristics contribute to runoff. They also present unique opportunities for the use of green infrastructure. Green Infrastructure Implementation
Presentation Title Appropriately located Green Infrastructure can decrease peak flow. Green infrastructure implementation
Presentation Title Green infrastructure implementation Impervious land uses Change land use characteristics without changing the land use
Presentation Title $ $ $ Green infrastructure does not replace gray infrastructure. Can reduce the capital costs and O & M costs of gray technology.
USEPA Partnership Opportunities Presentation to USEPA, July 9, 2009 Residential outdoor water use – URS Australian Experience
Presentation Title Outline Plant Selector Tool Love Your Garden TM WaterRight Gardens Webtool NSW Governments BASIX Initiative Key learnings for the USEPA
Presentation Title Average annual rainfall
Presentation Title title
Presentation Title Love Your Garden TM Behaviour Change Tools Rain gauge – defer irrigation events in response to rainfall Tap Tags – highlights seasonal frequency and runtime Customer report – a full summary of the assessor’s findings with recommendations and vouchers related to the recommendations.
