The RWMWD plans to carry out the following actions to protect the public from flooding: • Continue to maintain the RWMWD flood storage facilities and stone sewer systems • Continue to implement the RWMWD permitting program and the new RWMWD standards and criteria, which require volume control • Continue to identify, assess, and address potential flooding problems in the District. • Continue efforts to implement a permanent solution to the flooding problem on Weir Drive in Woodbury Continue to monitor lake levels within the RWMWD and modify predicted flood levels when necessary • Implement flood emergency response plans for homes and businesses where a structural solution is not feasible or cost-effective • Collaborate with cities to enforce minimum building elevations Develop and implement methods/programs for measuring, tracking, and reporting progress towards achieving flood control goals www.rwmwd.org Page 10
