<br />Slide LlD. Map showing the high-hazard zone after the relocation project, Boulder <br /> <br />The purple areas on this map show the high-hazard zone after the buildings were <br />removed. As you can see, the zone is much smaller than in the previous slide. Note <br />that the high school building is now out of the high-hazard zone. With the removal of <br />the buildings, more floodplain is now available for the floodwaters to spread out and <br />slow down, and the high school building can remain with assurance that students can <br />safely evacuate the building if flooding occurs. <br /> <br />Slide L11. Boulder Creek bike and walking path <br /> <br />In addition to the relocation project, the city purchased or acquired easements over <br />creekside property extending for six miles along the creek and five tributaries. The <br />centerpiece of this project is bike and pedestrian paths which allow you to walk or <br />bicycle almost anywhere in Boulder without crossing a street. <br /> <br />Slide L12. Sign announcing Annual Boulder Creek Festival <br /> <br />Every year, the residents of Boulder gather in the creek corridor for the Annual Boulder <br />Creek Festival on Memorial Day to celebrate the creek and the greenbelt including the <br />creek path. <br /> <br />Slide L13. Rubber duck race on Boulder Creek <br /> <br />A popular event during the festival is a rubber duck race. People pay $5 to enter a duck <br />in the race with the proceeds going to provide handicapped access to the creek. <br />Boulder's creekside project reduces the city's vulnerability to flood losses while at the <br />same time providing a safe and pleasant alternative to the automobile and a focal point <br />for community activities. <br /> <br />Slide L14. Wetlands along Charles River in Massachusetts <br /> <br />Protecting the ability of wetlands and marshes to store floodwaters is an important <br />aspect of flood hazard mitigation. This shows wetlands which are part of an 8,500-acre <br />preserve along the Charles River in Massachusetts. The Army Corps of Engineers <br />acquired the land and easements for $10 million. This was far less than the $100 million <br />estimated for upstream dams and levees needed to control an equivalent amount of <br />floodwater. The Corps report states that "nature has already provided the least-cost <br />solution to future flooding. . ." <br /> <br />Slide L15. Cluster development in Portola Valley, California <br /> <br />Development practices in watersheds can affect the frequency and height of floods on <br />rivers and streams. This shows a carefully planned cluster development in Portola <br />Valley, California featuring generous open space, native vegetation, limitations on <br />impervious surfaces and other features to reduce runoff from the site. <br /> <br />Script-Task L, page 3 <br />
