A one mile long section of roadway in Union City has been identified for a Green Streets renovation. This mile long roadway will be transformed from a typical urban residential collector road into a greenway boulevard purifying polluted storm water. These storm waters that typically end up in the San Francisco Bay ecosystem will be cleansed and purified by the installation of rain gardens at each intersection. The rain gardens will collect water and pollutants from nearby streets, homes and commercial uses and be cleansed. The following pollutants will be prevented from entering nearby Alameda Creek and ultimately the Bay: 45 lbs of Nitrogen, 7 lbs of Phosphorus, 5 lbs of Lead and Zinc along with 2,261 lbs of sediment. Each rain garden has been designed with drought tolerant plantings that provides new habitat for insects, reptiles and birds.
