Title: Using Rainwater to Grow Livable Communities
1Using Rainwater to Grow Livable Communities
Sustainable Stormwater Best Management Practices
(BMPs)
2Basic 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
3What Do BMPs Look Like?
4Rain Gardens Kansas City, MO
- Raingardens are bioretention areas that increase
infiltration, recharge groundwater, and improve
overall water quality
McCarthy Garden in Kansas City
5Ecoroof 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
6Detention and Infiltration AreasBelleview, WA
- Detention and infiltration areas reduce the
amount of off-site runoff and the speed with
which water enters local waterbodies
High flow storage area next to recreational
facilities
7Right of Way Enhancements Portland, OR
- Street right-of-ways can be modified to capture
runoff from roadways
Green Street Swales - New Seasons Market
8Residential Communities Denver, CO
- Detention areas, planted with native plants,
perform a stormwater retention and water quality
improvement function.
9What Can Sustainable Stormwater Practices Do
For Me?
10Benefits of Sustainable Stormwater Practices
- Reduce Runoff and Improve Water Quality
- Add Amenity
- Meet Regulations
- Save Money
- Enhance Funding Options
- Improve Wildlife Habitat
11Reduce 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
12Add 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.
13Meet 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
Vegetated swale at Costco parking lot
14Save 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.

15Enhance 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
16Improve Wildlife HabitatOrlando, FL
- Wetlands restoration, greenspace corridors, and
other environmental enhancements are standard
features in Orlando's re-development projects.
