Green Infrastructure

Green infrastructure is a natural approach that effectively takes water "out of the pipe" and puts it to work in an ecologically beneficial way - either to capture, clarify, infiltrate, or otherwise reuse it to maintain or restore natural hydrologic functions and habitat values. Today, many communities are taking a closer look at the watersheds in which they live, work, and play and are actively seeking to incorporate green infrastructure to improve the ecological functions within their watershed. Several environmental mandates - NPDES and MS4 Permits, Total Maximum Daily Loads (TMDLs), EPA Executive Orders, and new Stormwater Management regulations, for example - often form a regulatory driver for such efforts. In other cases, community and grass-roots initiatives are principle in the drive to improve aquatic ecology. JMT helps clients meet these goals and challenges.

At JMT, we recognize that watershed planning must be adaptive and comprehensive in order to integrate the management of stormwater runoff, agricultural runoff, septic systems, residential and commercial initiatives, and sanitary treatment processes. Green infrastructure is a major component of this approach.  The combined resources of JMT's Environment & Natural Resources group and our Water Resources group can provide the ecological and engineering design and construction management expertise to make such goals a reality. Our professionals can provide green infrastructure expertise and assistance in the following ways:

  • Stormwater Intervention and Retrofit Programs - rain gardens, stormwater wetlands, bioretention, porous pavements, green roofs, infiltration planters, etc.
  • Environmental Site Design (ESD) and Low Impact Development (LID) Practices
  • Stream & Ecological Restoration BMPs
  • Upland BMPs
  • Urban Hydrologic & Surface Water Flow Goals
  • Dry & Wet Weather Hydrodynamics
  • Peak Hydrograph Reduction
  • Rooftop Disconnection Programs
  • Groundwater Recharge
  • Rainwater Harvesting
  • Natural Landscape Preservation & Restoration
  • Comprehensive Land Use Planning
  • Forest Canopy Conservation Planning
  • Watershed Characterization & Planning
  • Community and Stakeholder Outreach
  • Grant Application Assistance
