Mosaic dots are installed throughout the site walkways and stairs. Fabrication started in June, 2009 with first installation in August. The dots are metaphors for water or water droplets. At west end of site, the dots are all blue and are arranged in ranks to show arrival of water at the site, as if constrained by all those underground pipes. At mid site, near the sediment pond, dots are blue and orange. The dots here are placed to tell the story of sediments settling out of the water. Orange indicates pollution. At northeast, outflow end of site, the dots are blue and green in a serpentine arrangement. Here the dots represent dynamic habitat enhancement from slow, clean water.
