The City of Gaithersburg, MD was impressed with the half mile fitness trail installed at the local headquarters of Lockheed Martin, so when the City Arborist was called to diagnose and offer solutions for a neighborhoods sidewalks separating he knew what to do.  He called Capitol Flexi-Pave to evaluate if a porous flexible paving would solve their problems in this neighborhood too.  The idea was put before the HOA board, and all parties agreed to proceed with this option.  Project was completed in May of 2014.
