    1. 1. Managing Stormwater Through LID to Restore an Urbanized Watershed W isely M anaging O ur U rban W ater R esources Neal Shapiro, City of Santa Monica LID Training, Marina del Rey June 28, 2007
    2. 2. OBJECTIVES Harvest urban runoff (dry/wet weather) for reuse (recharge or direct use) and pollution treatment Treat all dry weather and some wet weather urban runoff leaving the City Connect land use/design to the Hydrologic Cycle, reducing the disconnect and disruption of water flow Mimic nature; blend into the land Take proactive, watershed approach to reducing urban runoff problems Convert a perceived “waste” into a valuable resource for reuse - SMURRF
    3. 3. <ul><li>The Southern California Coastal Water Research Project, a leading marine research group in Southern CA, reported that storm water and urban runoff are the leading source of water pollution in the Los Angeles area; storm water pollution has increased 200-700 percent during the last 20 years. </li></ul><ul><li>Stormwater has become a lethal cocktail of pollutants that now constitutes the single greatest source of water pollutants, contributing 50-60 percent of the pollutant load. </li></ul><ul><li>Types and Sources of Pollutants </li></ul><ul><li>According to the US EPA, urban stormwater is the largest source of water quality damage in estuaries, the second largest for wetlands degradation, third largest impairment of lakes and fourth largest source of river damage. </li></ul>Urban Runoff – What is it? The Problem – Water Quality v. Quantity
    4. 4. The Watershed Level – Disrupting the Water Cycle <ul><li>How water flows through our environment </li></ul>
    5. 5. As hardscapes increase, water quality goes down.
    6. 8. Turning Impermeable to Permeable
    7. 9. Santa Monica: Tourist Destination
    8. 10. City Attractions
    9. 11. An Environmentally Concerned Community <ul><li>Concern Over the Environment </li></ul><ul><li>History of Political Activism </li></ul>
    10. 13. City Staff Working Together to Do More with Less Urban Runoff - EPD Open Spaces - Pets GIS – mapping CB/SDs, BMP locations Parks/Recs - irrigation Wastewater – CB/SD cleaning Engineering – BMP design in new projects; Airport gunite Building & Safety - COOs Planning – start of new project Enforcement – wasting water, no BMPs, pollutant spills City Attorneys – ordinances, enforcement, contracts Solid Waste – recycling/trash spills Street Sweeping Finance – parcel/runoff fees, grants Utilities – ind. waste, recycled water Resource Management
    11. 14. Tools of the Trade <ul><li>Education </li></ul><ul><li>Prevention </li></ul><ul><li>Ordinances </li></ul><ul><li>Treatment </li></ul><ul><li>Maintenance </li></ul><ul><li>Enforcement </li></ul><ul><li>Funding </li></ul>

    13. 16. Urban Runoff Mitigation, Stormwater Parcel Fee, UR Mitigation <ul><li>New Development Threshold: Value of new construction is 50% or greater compared to the replacement cost of the existing improvement </li></ul><ul><li>Stricter standard than LA Regional Water Board Standard; all land uses </li></ul><ul><li>About $1.2 million annually </li></ul><ul><li>New Development & Runoff Mitigation Plan, including City projects </li></ul><ul><li>Retain 0.75” </li></ul><ul><li>Good Housekeeping BMPs </li></ul><ul><li>Construction Site BMPs </li></ul><ul><li>Penalties - $500/day </li></ul><ul><li>Flexibility </li></ul><ul><li>In-Lieu Fee/Mitigation Banking </li></ul>
