Mac Watershed Rain Gardens Rain Barrels

  1. 1. Gutters to Gardens Capturing Urban Storm Water Diverting water from your downspout into rainwater catchment systems has several advantages ~Reduces the volume of water flowing to the sewer treatment facility ~Lowers the percentage of roof top rainfall as a component of urban runoff ~Backup source of water during times of drought or between rain showers ~Helps to keep our creeks and beaches clean
  2. 2. <ul><li>Naturally softened water - great for delicate houseplants, auto cleaning and window washing </li></ul><ul><li>Saves money by lowering your water bill </li></ul><ul><li>Reduces the need for additional tax dollars earmarked for sewer expansion </li></ul><ul><li>Chlorine-free water helps maintain a healthy biotic community in the soil </li></ul><ul><li>Educational tool for teaching residents about water conservation </li></ul>Gutters to Gardens Capturing Urban Storm Water

What are we trying to do? <ul><li>TWO GOALS….. </li></ul><ul><ul><li>Quantify the presence of the urban tree canopy </li></ul></ul><ul><ul><ul><li>How much land area in the city has tree canopy? </li></ul></ul></ul><ul><ul><li>Place a monetary value on the ecological services being provided by urban trees </li></ul></ul><ul><ul><ul><li>Can we calculate this for the entire city? </li></ul></ul></ul>
  7. 19. Urban Forest Assessment - Results AIR POLLUTION REMOVAL * Dollars are “externality” costs borne by society due to rising health care expenditures and reduced tourism revenue. Air Pollutant Pounds Removed per year** Money Saved from Removal* Carbon Monoxide 17,880 $7,631 Ozone 295,023 $906,375 Nitrogen Dioxide 107,281 $329,591 Particulate Matter: Less then 10 microns 196,682 $403,428 Sulfur Dioxide 44,700 $33,546 Total 661,566 $1,680,570 ** Based on Air Pollution conditions for the City of Milwaukee, Wisconsin
  8. 20. Urban Forest Assessment - Results STORMWATER RUNOFF April 2008 2-year, 24-hour Rainfall event: 2.37 inches Curve Number of existing conditions: 78 Curve Number if the trees were replace with buildings: 89 Additional Stormwater storage volume needed if the trees were replaced with buildings: 67,075,658 ft 3 Construction cost per ft 3 * $5.50 Total Stormwater Savings: $368,916,122 Annual costs based on payments over 20 years at 6% interest $32,163,789 per year     * Construction costs based on the cost to build just an ADS Storm Tech System to handle the additional stormwater
  9. 21. Urban Forest Assessment FINAL RESULTS SUMMARY <ul><li>Air Pollution Removal: $1,680,570 annually </li></ul><ul><li>Stormwater Runoff: $368,916,122 or $32,163,789 annually </li></ul><ul><li>Carbon Storage: $1,578,578 (presently stored in the trees) or $12,290 worth of storage per year </li></ul><ul><li>Water Quality Benefits: $???? </li></ul><ul><li>THE CITY’S 35 PERCENT TREE CANOPY PROVIDES TOTAL DOLLAR BENEFITS OF: $372,175,270 </li></ul>
