Commercial Street Reconstruction Porous PavementProvincetown, MassachusettsIn 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

A Low Impact Development Approach at Greenland Meadows Greenland, New HampshireUtilizing 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.
