After having success with the functionality and aesthetics of the Town’s permeable paver parking lot, the Town of Ashland was inspired to proceed with additional water quality retrofits as part of the Railroad Avenue street-scape project. In addition to street-scaping amenities such as landscaping, new street lights, lighted crosswalks, and decorative sidewalks, the project included Permeable Interlocking Concrete Pavement (PICP) in the on-street parking spaces, and micro-bioretention.

Morton Thomas and Associates, Inc. (AMT) provided the site planning and engineering design, assisted the Town with public meetings and consensus building in the community, as well as providing construction phase support.   The project was constructed in 3 phases. The first 2 phases were completed spring of 2014, and the third phase was completed in late 2015.

As the project progressed through the phases of work, the Town and AMT learned valuable lessons about the various applications of these water quality improvement measures. The Ashland Town Engineer and AMT’s lead design engineer, will both discuss the details of the project, lessons learned, and overall planning for incorporating green infrastructure into your municipal stormwater system.
