Green Infrastructure

Green infrastructure is the interconnected network of greenways, wetlands, parks, forest preserves and native plant vegetation, that naturally manages stormwater, reduces flooding risk and improves water quality. The latter can be found in raingardens, bioswales, green streets, green roofs, and other landscaping.

PlanGreen will help you identify design and construction savings of 20% to 50% over traditional storm sewer systems by developing technologies to:


4th Avenue Bioswale

  • Use green infrastructure, e.g., green streets, raingardens, green roofs, trees, restored wetlands, greenways, and other native vegetation
  • Infiltrate stormwater to recharge streams and rivers
  • Reduce pressure on the combined sewer system
  • Soften streetscapes
  • Lessen the urban heat island effect
  • Calm traffic
  • Enhance habitat for native pollinators

Projects that add to your green infrastructure can also foster community cohesiveness by engaging residents in the planning, planting and maintenance of the sites.

Let PlanGreen help you to adopt policy, technology and landscape practices to meet the needs of your community or business. We have 20 years of planning (and planting) experience and hundreds of photos, plans, research reports and multiple case studies to draw on.


Mary Vogel is a champion of sustainability who is in the forefront of policy and practice for people and neighborhoods.  I worked alongside Mary when she successfully spearheaded the creation of Washington, DC’s Green Building Act, the U.S.’s first municipal green building law.  In developing this key legislation, Mary led and empowered policy makers, business leaders and everyday residents who care about their neighborhoods.  I have also seen Mary inspire others as an expert on sustainable land use and planning for the Urban Land Institute and other leading organizations.  Mary is ahead of her time, but knows how to bring others along with her!
