Those big “dirt” piles at Brightwalk have a purpose. The piles accumulated during clearing the land for construction – old sidewalks, foundation concrete and other materials all make up the piles. Larger concrete pieces were pounded down and dirt added. The piles will be used over the course of constructing Brightwalk for non-garden and non-park areas like roads. So when you visit Brightwalk during our construction phase, excuse our recycling and look for shrinking mounds in the months to come.
