7 Flooding Caused by Hurricane Irma Combination of Tide and Storm Surge Date Day Time Pred High/ Low 9/10/2017 Sun 5:05 AM 0.12 L 9/10/2017 Sun 11:27 AM 4.46 H 9/10/2017 Sun 5:44 PM 0.43 L 9/10/2017 Sun 11:45 PM 3.95 H 9/11/2017 Mon 5:56 AM 0.15 L 9/11/2017 Mon 12:19 PM 4.47 H 9/11/2017 Mon 6:42 PM 0.55 L Recorded Rainfall Amounts Hurricane Matthew: 5.64 inches Hurricane Irma: 6.57 inches Peak Stage at Trident Pier, Port Canaveral: 6.5 ft, NGVD Page 7

8 Stormwater Adaptation Measures Top Duckbill Tidal Automatic Hinged Style Floodgate Tidal Flap Gate Check With Manual Floodgate Valve Mechanism Page 8

9 Stormwater Adaptation Measures PROS CONS Prevents storm surge from backing-up into the upstream drainage system Can be blocked by sedimentation or debris and stop functioning Causes elevated water levels in the upstream drainage systems Sediment and debris preventing flapgate from performing properly Page 9

10 Stormwater Adaptation Measures RECOMMENDATION: Install duckbill check valves at : Oakwood Avenue Outfall Pipe (~$60K) Goodwin Avenue at Ocean Avenue (~$10K) Goodwin Avenue at 2 nd Avenue (~$10K) South Pine Street at Ocean Avenue (~$20K) South Pine Street at 2 nd Avenue (~$10K) TIMELINE FOR INSTALLATION: The valves are planned to be installed during June 2018 Page 10

11 It is important to note that the duckbill check valves will not prevent structural flooding associated with a similar high tide/storm surge event to Hurricanes Matthew and Irma. Page 11

30 CITY S POTENTIAL PARTICIPATION IN THE LOCAL MATCH Anticipated Elevation Project Payment Schedule*: 25% Payment when structure is elevated 25% Payment upon final completion 25% Payment when equipment is mobilized 25% Payment when elevation contract is signed * Subject to change based on final agreement with contractor Page 30

31 CITY S POTENTIAL PARTICIPATION IN THE LOCAL MATCH Anticipated Project Payment Schedule: 1. The City will pay the contractor according to the agreed-upon payment schedule. 2. The homeowner will pay the City for their local match responsibility. Early coordination between homeowners and their flood insurance agents is crucial to determine eligibility for ICC benefits. Page 31

32 What to Expect Be able to provide: Flooding History (questionnaires, photographs, flood insurance claims) FEMA-required forms that demonstrate: Voluntary Participation Legal status Privacy Release Coordination with Elevation or Demolition Contractor Coordination with City of New Smyrna staff Public Meetings Public Notice in local newspaper Three (3) years to project completion Page 32

33 What to Expect Awaiting FEMA s release of the Notice of Funding Availability (NOFA) for Hurricane Irma (presently in upcoming status) The NOFA will establish the amount of funding allocated to Volusia County and other Florida Counties City to continue to coordinate with the Volusia County Local Mitigation Strategy (LMS) group for project support This City project will be ranked by the LMS group against other projects submitted by the County, other cities, and Private Non-Profit corporations Page 33

34 What to Expect Per FEMA guidelines, the following applies to structures to be mitigated: Properties must maintain a flood insurance policy for the life of the structure (regardless of the transfer of ownership). Homeowners will need to record with Volusia County land records a notice including the name of the current homeowner, a legal description of the property, and a notice of flood insurance requirement. Failure to maintain flood insurance on the mitigated property may prohibit the owner from receiving Federal disaster assistance with respect to said property in the event of a future flood disaster.
