Title: Using Rainwater to Grow Livable Communities


1
Using Rainwater to Grow Livable Communities
Sustainable Stormwater Best Management Practices
(BMPs)
2
Basic Principles
  • Treat water as a resource, not a waste product
  • Design to mimic or replicate the natural
    hydrology of a site
  • Design to address issues of water quality,
    quantity and amenity
  • Accommodate the standards and expectations of the
    local community
  • Infiltrate, detain, retain
  • Start small, build from there
  • Collaboration is key

3
What Do BMPs Look Like?
4
Rain Gardens Kansas City, MO
  • Raingardens are bioretention areas that increase
    infiltration, recharge groundwater, and improve
    overall water quality

Ecoroof Chicago, IL
  • An ecoroof is a roof that is planted with
    vegetation. It can reduce the heat imprint of a
    building and reduce off-site runoff

6
Detention and Infiltration AreasBelleview, WA
  • Detention and infiltration areas reduce the
    amount of off-site runoff and the speed with
    which water enters local waterbodies

facilities

Right of Way Enhancements Portland, OR
  • Street right-of-ways can be modified to capture
    runoff from roadways

Residential Communities Denver, CO
  • Detention areas, planted with native plants,
    perform a stormwater retention and water quality
    improvement function.

What Can Sustainable Stormwater Practices Do
For Me?
10
Benefits of Sustainable Stormwater Practices
  • Reduce Runoff and Improve Water Quality
  • Add Amenity
  • Meet Regulations
  • Save Money
  • Enhance Funding Options
  • Improve Wildlife Habitat

11
Reduce Runoff Burnsville, MN
  • Monitoring has shown that
  • The rain gardens in the Burnsville rain garden
    demonstration project capture at least (and often
    more than) the first 0.9 of rainfall
  • There is a 90 reduction in runoff rates from the
    neighborhood with rain gardens as compared to a
    similar neighborhood without rain gardens

12
Add Amenity Philadelphia, PA
Vacant lot at 2300 North 3rd Street before
greening
Site was regraded to capture stormwater and
planted with trees, shrubs, and grass
  • The Philadelphia Public Works Department is a
    partner in the Pennsylvania Horticultural
    Society's Neighborhood Transformation Initiative,
    which transforms vacant lots into
    community-friendly spaces.
  • Converted spaces offer stormwater management
    benefits because the park-like spaces are
    outfitted with berms and swales that collect and
    infiltrate rainfall and runoff, and natural
    vegetation promotes evapotranspiration.

13
Meet Regulations Truckee Meadows, NV
  • A Regional Stormwater Management Quality Program
    was developed in response to TMDL and NPDES Phase
    I permit requirements
  • Program components include
  • Structural BMP Controls
  • Land Use Planning and LID Tools
  • Public Outreach

14
Save Money Seattle, WA
  • Seattle Public Utilities has projected that its
    Natural Drainage Installations are at least 25
    percent less expensive than traditional
    stormwater systems due to decreased build and
    infrastructure maintenance costs.

Enhance Funding OptionsMilwaukee, WI
  • The Milwaukee Metropolitan Sewerage District
    partnered with Alterra Coffee Roasters to
    renovate a historic site with stormwater
    management features to provide community amenity
    and stormwater management education

Stormwater is managed entirely on-site at the
former Milwaukee River Flushing Station, now an
Alterra Coffee Roasters café and interpretive
center
16
Improve Wildlife HabitatOrlando, FL
  • Wetlands restoration, greenspace corridors, and
    other environmental enhancements are standard
    features in Orlando's re-development projects.
