  • 1. Real World Implementation of Sustainable Development Robert Roseen, PhD, D.WRE, PE rroseen@geosyntec.com 603-205-8056 June 25, 2014
  • 2. Commercial Street Reconstruction Porous Pavement Provincetown, Massachusetts In 2012 Provincetown began the installation of over 5,000’ of the first “Porous Municipal Main Street”. The project addressed existing infrastructure problems with flooding and drainage along a main thoroughfare that has tremendous traffic during the busy tourist season.. The harbor and Commercial Street are the economic driver for the Town. Beach closures affect economy and public perception Year-round population of around 3,000 Seasonal population increases to approximately 30,000 Summer tourism can bring in half a million visitors to Commercial Street

  • 6. A Low Impact Development Approach at Greenland Meadows Greenland, New Hampshire Utilizing an LID approach that featured acres of porous asphalt and a gravel wetland, a cost- competitive drainage system was designed for a large retail development. The total impervious area of the development – mainly from rooftops and non-porous parking areas – is approximately 25.6 acres. This project had an estimated 26% cost reduction due to cost avoidance in associated drainage infrastructure (ponds and piping) with the use of Low Impact Development.
  • 7. Greenland Meadows Commercial, Greenland, NH • “Gold-Star” Commercial Development • Cost of doing business near Impaired Waters/303D • Brownfields site, ideal location, 15yrs • Proposed site >10,000 Average Daily Traffic count on >30 acres
  • 8. Comparison of Unit Costs 26% savings on total cost of SW infrastructure
  • 9. LID as a Climate Adaptation Tool and Community Resiliency Of 15 largest events since 1934: • 8 have occurred in last 25 years • 5 have occurred in last 15 years • 3 have occurred in last 5 years LID zoning mitigated flooding increase by 53%
