The document discusses green infrastructure, defined as an interconnected network of green spaces that includes natural areas, conservation lands, and protected open spaces, which are managed for their ecological value and human benefits. It highlights various components such as storm water green streets, green roofs, rain gardens, and subsurface detention systems, emphasizing their role in managing storm water and providing ecological advantages. The benefits of implementing green infrastructure include reduced storm water runoff, enhanced groundwater recharge, improved air quality, and increased land values.

2. Green infrastructure

3. Green infrastructure is interconnected green
space net work population.
It includes natural areas and features, public
and private conservation lands, working lands
with conservation values and other protected
open spaces.
It is planned and managed for its natural
resources values and for the associated
benefits it confers to humans.

4. WHY GREEN INFRASTRUCTURE?

5. GreenPrint shows where Targeted Ecological Areas (TEAs) occur
and how the many programs within our State government work
together to protect our most ecologically valuable areas.

Blue Roofs
Rain Gardens
Permeable Paving
Subsurface Detention
Cisterns and Rain Barrels

7. RIGHT-OF-WAY BOSWELLS

8. STORM WATER GREEN STREETS
 Storm water Green streets are planted areas designed to collect
and manage storm water that runs off the streets and sidewalks.

10. BLUE ROOFS

11. RAIN GARDENS

12. PERMEABLE PAVING

13. SUBSURFACE DETENTION
 Subsurface Detention Systems with infiltration capability provide
temporary storage of storm water runoff underground.
 These systems have an open-bottom and can incorporate
perforated pipe and storm water chambers for added detention
volume.
 Systems are primarily designed with a gravel bed that stores
water until it can infiltrate into the ground.

14. CISTERNS AND RAIN BARRELS

16. BENEFITS
 Reduced and delayed storm water runoff volume
 Enhanced groundwater recharge
 Reduced storm water pollutants
 Increased carbon sequestration
 Urban heat island mitigation and reduced energy
demands
 Improved air quality
 Additional wildlife habitat and recreational space
 Improved human health
 Increased land values
