1 <br />2 Employ development and redevelopment principles and strategies, site development <br />3 techniques, engineering solutions, and best practices to reduce flood damage risk, flood <br />4 damage claims and losses resulting from high -tide events, storm surge, flash floods and <br />5 the impacts of sea level rise. <br />6 <br />7 Policies <br />8 9A. Continue to maintain, protect and promote revegetation of coastal Mangrove <br />9 forests, coastal hammocks and other natural coastal vegetative communities which <br />10 remain in the City. <br />11 9B. Continue to protect, stabilize and enhance beaches and dunes through beach <br />12 renourishment, restoration of the submerged breakwater structure, potential sand <br />13 erosion barriers, planting and maintaining appropriate dune vegetation, directing <br />14 beach access through designed crossings such as elevated walkways, and prohibiting <br />15 uses and improvements that are incompatible with dunes. <br />16 9C. Promote the protection and enhancement of offshore reef communities consistent <br />17 with the Dolicies of this element. <br />18 <br />9D. <br />The City shall adopt minimum seawall elevation and design criteria for both public <br />19 <br />and private seawalls throughout the City in conformance with the most recently <br />20 <br />adopted Miami -Dade County Flood Criteria Map. <br />21 <br />22 <br />9E. <br />The City shall develop strategies for requiring or causing the repair, enhancement, <br />23 <br />or replacement of seawalls located on both public and private properties, based <br />24 <br />upon existing conditions, year of projected impacts and economies of scale to <br />25 <br />reduce cost, ensure a comprehensive approach, and minimize disruption from <br />26 <br />flooding. Strategies may include a combination of regulations (such as requiring <br />27 <br />repair or enhancement of seawalls as a condition of permits for other work on <br />28 <br />waterfront properties) and funding strategies (such as grants and assessments) for <br />29 <br />the City to undertake the work on a phased city-wide basis. <br />30 <br />31 <br />9F, <br />The City shall continue to prioritize stormwater drainage improvements as funding <br />32 <br />allows. <br />33 <br />34 <br />9G. <br />Pursuant to Miami -Dade DERM requirements, all public wastewater and potable <br />35 <br />water collection and transmission systems shall be protected from floodwaters and <br />36 <br />inflow by having all mechanical and electrical equipment and all system openings <br />37 <br />placed above the base flood elevation plus applicable freeboard and sea -level rise. <br />38 <br />Freeboard shall be no less than 24 inches for systems that serve essential facilities <br />39 <br />(e.g., hospitals) and facilities that are required to have an emergency generator by <br />40 <br />law, and 12 inches for all other systems. When the required minimum elevations <br />41 <br />cannot be attained for system openings (e.g., manholes, wet wells), openings shall <br />42 <br />be elevated to be protected from a 10 -year storm and include water -tight and <br />43 <br />bolted covers/hatches. The entire assembly, structure, ring, frame, etc., shall be <br />44 <br />water -tight to sustain as a minimum, a water column pressure equivalent to the <br />45 <br />difference between opening elevation and minimum required elevation. <br />46 <br />47 <br />9H. <br />Development within the special flood hazard area shall be designed and <br />48 <br />constructed using methods, practices and materials that minimize flood damage <br />Underlined text is added and stricken text is deleted <br />16 o18 <br />
