A method to close openings, such as the driveway. Generally, this requires "human <br />intervention," meaning someone needs to be available and have enough time to take <br />action. <br />. A system to prevent sanitary sewer backup from flowing into the building, such as a back <br />flow valve. <br />. A system of drain tile (perforated pipes) that collects water that falls or seeps into the <br />protected area and sends it to a collecting basin or "sump." <br />· A sump pump to send the collected water outside the barrier. <br />. Power to operate the sump pump around the clock during a storm. <br /> <br />Cost: The cost of a local barrier depends on the depth of flooding and the amount of engineering <br />put into the design. Where flooding is only inches deep and of short duration, almost any barrier <br />of concrete or earth will work. <br /> <br />Brookglen Area Analysis - DRAFT <br /> <br />20 <br /> <br />9/8/2008 <br />
