HEALTH OF THE RUN
Take artistic license to help drive toward the goal of increasing awareness of water quality and wildlife habitat and biodiversity.
SIGNS OF CARE
Artistically amplify selected elements of the stream restoration to reinvigorate the experience of the Run and raise consciousness and foster
care for its watershed.
LESSONS ON THE RUN

watermark for the watershed and a landmark for the region.
VISIBLE RESTORATION PROCESS
Set the artistic tone and offer a prototype for rendering unique legibility of the restoration process along the entire length of the Run.
FUN AT THE RUN
Create artful objects and playful places to inspire the imagination of the next generation that deserve to inherit a healthy waterway.
