LTC 607-2017 Beach Restoration & Renourishment Overview & UpdateMIAMIBEACH OFFICE OF THE CITY MANAGER NO. LTC# 607-2017 LETT R TO COMMISSION TO: Mayor Dan Gelber and Members f the City fffmmission FROM: Jimmy L. Morales, City Manager DATE: December 19, 2017 SUBJECT: BEACH RESTORATION & REN URISH ENT OVERVIEW & UPDATE The purpose of this LTC is to provide an overview and update on the beach restoration and renourishment efforts. The beaches in Miami Beach are owned by the State of Florida and managed by Miami -Dade County. In 1968, Congress authorized the Beach Erosion Control & Hurricane Protection Project for Dade County (the Project) for 9.3 miles of shoreline between Government Cut and Bakers Haulover Inlet. In 1975, the U.S. Army Corps of Engineers (USACE) began construction of this segment and was given authorization to maintain the original design template for the next 50 -years. Following Hurricane Irma, the USACE completed the attached Project Information Report that evaluated if the Miami Beach segment of the Project qualified for funds under Flood Control and Coastal Emergency (FCCE) rehabilitation. The study found that more than one-third of the historically placed sand has been lost and approximately 730,000 cubic yards of sand was lost between the pre -storm to post -storm template. While the USACE confirmed that the Project had significant damage from Hurricane Irma, the Project does not meet the eligibility criteria for financial assistance. To be eligible for rehabilitation assistance, the proposed work must have a benefit to cost ration greater than 1.0. When the cost to benefit ratio was calculated for the initial project in 1975, recreational benefits were included in the project justification. However, the federal government no longer allows for recreational benefits to be used when calculating benefit to cost ratio. It should also be noted that the USACE has not completed an updated economic study since 1975, as such the current beachfront real estate values are not used when calculating the hurricane and erosion protection benefits. In 2024, the 50 -year federal authorization will expire. This is ideal timing for the city to request that the USACE update their studies and to set begin discussions for the next round of federal participation. Our next steps are to coordinate with our state and federal partners to identify funding and develop a strategy which will properly define the value of renourishment projects to our economy. We will be engaging our recently selected federal lobbyist to assist with the planning and implementation of our beach management strategy.

PIR Review Checklist 27 Dade County Beach Erosion Control and Hurricane Protection Project REHABILITATION EFFORT FOR THE BEACH EROSION CONTROL AND HURRICANE PROTECTION, DADE COUNTY, FLORIDA Part I. Executive Summary. This report was prepared at the request of the project sponsor in a letter dated September 21, 2017. This report finds that there is insufficient justification for Flood Control and Coastal Emergency (FCCE) rehabilitation of Miami Beach under Public Law (P.L.) 84-99. The Dade County Beach Erosion Control and Hurricane Storm Protection Project (HSPP) consists of two segments: the Main Segment and the Sunny Isles Segment. This Project Information Report (PIR) focuses on the Main Segment only. The authorized project for the Main Segment has a berm height of 9 feet mean low water (MLW) and a design berm width of 50 feet. This report finds that the significant storm criteria has been met. Hurricane Irma was considered to be an extraordinary storm per Engineer Regulation (ER) 500-1- 1, 5-20.f along the East Florida Coast. Hurricane Irma made landfall along the Southwest Florida coast as a major, category 3 hurricane on 10 September 2017 and traveled northward along the Florida peninsula for the next 24 hours with hurricane force winds stretching nearly from coast to coast and tropical storm force winds extending much further beyond that. The storm had devastating consequences on Federal coastal storm risk management Projects causing extensive beach and dune erosion along several hundred miles of Florida coastline. Due to the intensity and size of the storm coupled with a nor'easter in the time prior to tropical storm force wind arrival, high-energy waves and elevated water levels (storm surge and wave setup) affected areas far from the core of the storm over a duration of greater than a day. The combination of high waves and water levels over a long duration created the potential for extensive beach erosion. This report finds that the "significant damage determination" criteria as defined in ER 500-1-1, paragraph 5-20.e.(2) has also been met. The criteria in paragraph 5- 20.e.(2)(a) is met as the cost to restore the Project to the design level of protection is estimated at $48,023,000 without mobilization and demobilization costs, which is greater than $1,000,000 and is approximately 36% of the original construction cost of $134,187,000 which is greater than 2% of the original construction cost. Additionally, the criteria in paragraph 5-20.e.(2)(b) is also met as the cost to restore the Project to the design level of protection is greater than $6,000,000. As the damages to the Main Segment met the significant damage criteria under ER 500-1-1, paragraph 5-20.e.(2), two scenarios were considered in the economic analysis in order to establish the best allocation of resources and to determine if the second criteria is economically justified (ER 500-1-1, paragraph 5-20 (a)): (1) ES -1 Dade County Beach Erosion Control and Hurricane Protection Project Alternative 1 - FCCE restoration of the design template and material necessary to maintain the restored design profile template through the next storm season and (2) Alternative 2 - simultaneous FCCE and CG (Construction General) cost -shared efforts to bring the Project to the full Construction Template. The benefits were expressed at the last approved document price level of the 2016 LRR and the costs of the emergency restoration were deflated back to this price level. The FY 18 discount rate of 2.75% was used. Alternative 1 (FCCE only restoration) is not economically justified; the benefit -to -cost ratio (BCR) is approximately 0.05 to 1.0. Therefore FCCE funding is not recommended. The Main Segment is not eligible for P.L. 84-99 assistance as it does not meet the criteria as outlined in ER 500-1-1 Paragraph 5-20.a. in terms of economic justification. ES -2 Dade County Beach Erosion Control and Hurricane Protection Project Part 11. Basic Report. 1. NAME AND LOCATION. Dade County is located along the southeast coast of Florida, and contains the city of Miami. Dade County lies between Broward County (north of Dade) and Monroe County (south of Dade), Figure 6-1. The Dade County shoreline extends along two barrier island segments separated from the mainland by Biscayne Bay. The barrier islands vary in width from about 0.2 to 1.5 miles, with an average width of about 0.5 miles. Elevations along the entire coastal region (and much of the mainland) are low whereas elevations along the barrier islands are generally the highest along the Atlantic Ocean shorefront, and slope gradually downward toward the bay. All distances referenced within this report are in statute miles. 2. PUBLIC SPONSOR. Miami -Dade County Board of County Commissioners Carlos Gimenez, Mayor 3. POC FOR PUBLIC SPONSOR.

PROJECT AUTHORIZATION. Section 3 of the Rivers and Harbors Act of 1930 (P.L. 71-520) authorized the Chief of Engineers to study effective means of preventing erosion of the shores of coastal and lake waters by waves and currents, which would include the Project area. Congress authorized the Beach Erosion Control and Hurricane Protection Project (BEC and HP Project) for Dade County, Florida in Section 203 of the Flood Control Act of 1968 (P.L. 90-483). In addition, Section 69 of the 1974 Water Resources Development Act (P.L. 93-251) included the authorization for initial construction by non -Federal interests of the 0.85 -mile segment along Bal Harbour Village, immediately south of Bakers Haulover Inlet. The Main Segment authorized project, as described in House Document 335/90/2, provided for the construction of a protective and recreational beach and a protective dune for 9.3 miles of shoreline between Government Cut and Bakers Haulover Inlet (encompassing 1 Dade County Beach Erosion Control and Hurricane Protection Project Miami Beach, Surfside, and Bal Harbour), and for the construction of a protective and recreational beach along 1.4 miles of shoreline at Haulover Beach Park. 5. PROJECT CLASSIFICATION. The primary purpose of the project is to provide storm damage reduction to structural improvements threatened by erosion. The authorized project at Miami Beach has a protective and recreational beach with a dune for beach erosion control and hurricane protection along 9.3 miles and a protective and recreational beach along 3.7 miles. The design berm width is 50 feet at elevation +9.0 feet MLW for the Main Segment consisting of 10.5 miles. This project is not designed for a certain storm frequency or event. While the berm height of +9.0 feet MLW represents the 10 -year storm surge elevation it is specifically designed per EM 1110-2-1101 (Coastal Engineering Manual) which stipulates that the construction berm elevation should be the same or slightly Tess than the natural berm crest elevation. It is understood that the construction berm will erode and the beach fill will be redistributed to a more naturally shaped profile. The widths of the design berm are optimized based on economic analysis in accordance with ER 1105-2- 100 (Planning Guidance Notebook). 6. DESIGN DATA OF PROJECT. The authorized project, Figure 6-1, provides for a protective dune along the ocean shoreline of Dade County. The Main Segment includes a dune with a 20 -foot wide crown at elevation 11.5 feet MLW and side slopes of 1 vertical on 5 horizontal down to a protective and recreational beach. It includes the following: a level berm 50 feet wide at elevation 9 feet MLW and a natural slope seaward as would be shaped by wave action, all for beach erosion control and hurricane flood protection along the 9.3 miles of shore between Government Cut and Bakers Haulover Inlet; a protective and recreational beach with a 50 -foot level berm at elevation 9 feet MLW; and a seaward slope as would be shaped by wave action for beach erosion control along 1.2 miles of shore at Haulover Beach Park. Periodic nourishment is authorized for 50 years. Work on the Main Segment (as originally authorized) began in July 1975 and was completed in January 1982 at a total contract cost of about $48 million. Due to the length of the shoreline involved, the project was constructed in several phases, with each phase administered under a separate contract. 2 Dade County Beach Erosion Control and Hurricane Protection Project which resulted in negative findings. No other PL84-99 reports have been prepared for the Dade County Project. 10. DISASTER INCIDENT. Hurricane Irma made landfall along the Southwest Florida coast as a major, category 3 hurricane on 10 September 2017 and traveled northward along the Florida peninsula for the next 24 hours with hurricane force winds stretching nearly from coast to coast and tropical storm force winds extending much further beyond that. The storm had devastating consequences on Federal coastal storm risk management Projects causing extensive beach and dune erosion along several hundred miles of Florida coastline. Due to the intensity and size of the storm coupled with a nor'easter in the time prior to tropical storm force wind arrival, high- energy waves and elevated water levels (storm surge and wave setup) affected areas far from the core of the storm over a duration of greater than a day. The combination of high waves and water levels over a long duration creates the potential for extensive beach erosion. Along the Florida East coast, the coastal NOAA gauges nearly replicated (difference of 0.01 ft at Lake Worth Pier) or exceeded (at Virginia Key, Trident Pier, and Mayport) the peak water levels recorded during the extraordinary storm, Hurricane Matthew, in 2016. Only the Fernandina Beach gauge registered a significantly lower peak water level (0.56 ft lower) but the value of 6.34 ft NAVD88 still represents an approximately 75 year exceedance water level value based on NOAA data at this location while the nearby Mayport gauge exceeded the 100 - year exceedance water level value (5.58 ft NAVD88 recorded versus a 100 -year exceedance value of 4.72 ft NAVD88). Irma created wave heights of 22.0, 26.6, and 21.0 ft at the National Data Buoy Center's (NDBC) Ft. Pierce, Canaveral 20 NM, and Offshore Fernandina Beach wave gauges respectively which rank as the top 3rd 2nd and 1St wave heights in the USACE WIS database and are comparable to those experienced during 2016 Hurricane Matthew. Based on the observed water level, wave, and wind data, SAJ has found a preponderance of evidence to support the fact that Hurricane Irma is an extraordinary storm per ER 500-1-1, 5- 20.f along the East Florida coast. 11. DAMAGE DESCRIPTION Damage to the Main Segment of the Dade County, Florida Beach Erosion Control Project due to Hurricane Irma consisted of some erosion in the project area. Overall, the project appeared to fair pretty well, based on a visual assessment following Hurricane Irma. Figure 11-1 provides an example of how the project area looked following the storm. Inspections following the passing of Irma noted no significant damage to shorefront infrastructure within the project area caused by erosion. 6 Dade County Beach Erosion Control and Hurricane Protection Project =figure 11-1: Post Storm view of the beach looking south near FDEP R -Monument R-45. In order to quantify the degree of storm damage to the project area from the hurricane a volumetric change analysis was performed. The most recent survey to use as a pre -storm survey for most of the project area was post Hurricane Matthew Lidar data collected in November 2016. Two small hotspot areas had more recent survey data (USACE survey #16-125) collected in March 2017 that was used as the pre -storm survey for these areas. USACE survey #16-125 was the post - construction monitoring survey associated with the two hot spot truck haul fills completed in 2016 and 2017. The 46th Street hotspot fill (R-53.5 to R-56) was completed in October 2017 and the 55th Street hotspot fill (R49 to R50.75) was completed in February 2017. The Lidar data collected following Hurricane Irma in September 2017 by USACE JALBTCX served as the post -storm survey for the entire Main Segment. USACE compared the pre- and post -storm survey surfaces using ArcMap 10.4.1 and calculated volumes changes for the project area where overlapping data coverage was available. A site inspection conducted by SAJ staff on September 14, 2017 revealed minimal damage to the project as a direct result of Hurricane Irma. Figure 11-2 shows a profile in the middle of the Haulover Beach portion of the project area and Figure 11-3 shows an elevation change plot showing areas of erosion and accretion of the Haulover Beach area based on the pre- and post - storm surveys. In this portion of the project, most of the erosion has occurred in scattered areas along the foreshore slope and submerged offshore profile while the upper beach and dune remained mostly unchanged. 7 Dade County Beach Erosion Control and Hurricane Protection Project 15 10 co > • 5 0 v -5 ft, • -10 °—�,' • -15 –r- -20 0 100 200 300 400 500 600 700 800 900 1000 R-55 — Design Berm Distance from ECL (feet) —Construction Berm Post Matthew (Lidar) — 16 025 (Mar 2017) —Post Irma (Lidar) Figure 11-10: Beach profile at R-55 in the 46t" Street hot spot area of Miami Beach. 20 15 O 10 z 5 .v) 0 0 • -5 R-65 -20 100 200 300 400 500 600 700 800 900 1000 Distance from ECL (feet) —Design Berm —Construction Berm Post Matthew (Lidar) —Post Irma (Lidar) Figure 11-11: Beach profile at R-65 in the southern portion of Miami Beach.

(North is to the left). 12 Dade County Beach Erosion Control and Hurricane Protection Project Table 11-1 provides a volume change summary broken down by areas within the Main Segment having a different Erosion Control Line (ECL) or different pre -storm survey availability. Overall, pre- to post -storm erosion of 731,876 cubic yards (cy) was calculated for the project area from R-19.5 to R-74.5. This volume calculation extends seaward from the ECL to the Depth of Closure (DoC) approximated by the the -20 feet NAVD 88 contour from the Post -Irma Lidar survey. Much of the pre- to post -storm volume change has occurred below mean high water. The volume needed to restore the authorized design template from the pre -storm survey is 717,761 cy and the volume needed to restore the authorized design template from the post -storm survey is 796,597 cy. Therefore, 78,837 cy eroded within the design template along the entire Main Segment. The volume needed to restore the full construction template from the post -storm survey is 1,909,025 cy along the entire Main Segment.

The pre -storm survey data available may not accurately capture the pre -storm condition of the beach in certain areas due to the period of time between the pre -storm survey and the actual storm event; however, it is the most recent survey data available. Portions of the project have experienced erosion into the authorized design berm. The eroded profile leaves portions of the project more vulnerable to future erosional events and coastal storm damage. 13 Dade County Beach Erosion Control and Hurricane Protection Project 15. ECONOMICS. OVERVIEW This economic analysis for Flood Control and Coastal Emergencies (FCCE) has been conducted in accordance with EP 500-1-1 (2001), Appendix D, and was developed to compare the economic benefits versus the economic costs of emergency restoration and nourishment activities for the Main Segment. Emergency restoration and nourishment is defined by P.L. 84-99 (as amended by WRDA 2014) as the placement of material on the beach of the subject project in order to repair and restore the project to the design level of protection (i.e. design template). The quantity of sand used for benefit determination for P.L. 84-99 Rehabilitation Assistance will be the amount of sand necessary to restore this profile and maintain the profile into the next storm season, hereafter referred to as FCCE quantity. The primary objective of this analysis is to determine whether or not FCCE emergency restoration is economically justified (i.e. has a benefit -cost - ratio greater than 1.0). If FCCE placement is economically justified, a secondary objective is to compare FCCE restoration to a full construction action based on the authorized nourishment. It is important to note that the analysis for all alternatives is strictly a comparison of remaining costs and remaining benefits. Any indication of a benefit -cost ratio (BCR) in the following paragraphs and appendices should be treated not as a "Total BCR" but as a remaining -benefit -remaining -cost ratio. KEY ASSUMPTIONS Initial construction of the Main Segment began in 1975. As of October 2017 (FY18), the remaining period of Federal participation is seven years, concluding in 2024, with an authorized nourishment interval of five years. The period of analysis (POA) for FCCE placement is assumed to be six years. This assumption is based on the fact that significant storm damage to the project would trigger the periodic nourishment to be shifted forward to the earliest possible date. The least amount of time for a nourishment to be approved in the normal budget process, undergo the normal contract bid process, and begin construction would be six years. FCCE nourishment is assumed to carry the project until that periodic nourishment occurs and therefore has a POA of six years, measured from the fiscal year of this report. A future -with project (FWP) condition, which is the FCCE placement, will be compared to a future -without project (FWOP) condition (i.e. no action), in which annual erosion continues unabated for six years, in order to establish the average annual benefits of FCCE placement. Despite the fact that much of the Main Segment was originally justified on recreation benefits' policy requires that incidental benefits not be part of the analysis. Benefits will be expressed at the price level from the authorizing document, the 1975 GDM, and the costs of the Recreation benefits of the authorizing document are $16,349,000 AAEQ, 1975 price level using the discount rate of 3.25% 16 Dade County Beach Erosion Control and Hurricane Protection Project emergency restoration will be deflated back to this price level. It is important to note that the CWCCIS does not have quarterly figures dating back to 1975 and thus the annual index figure will be used for this date. Economic Evaluation of FCCE Restoration to Design Template (Alternative One) BENEFITS The authorizing document design profile estimate of coastal flood damage reduction benefits has been applied as the initial assessment point. Engineering has provided the incremental Toss in cubic -yardage of sand from the design profile. This lost quantity is to be subtracted from the total cubic -yardage of 11,254,000 utilized to initially construct the authorized project design profile in order to establish the starting condition of the design template in the FWOP. The starting point in the FWP is the full design template plus the estimated advanced nourishment required to provide protection into the next storm season, calculated by engineering as 796,597CY. To estimate benefits in both the FWOP and FWP the proportion of volume in the design template that remains after the annual erosion of 190,000CY has been factored in will serve as a proxy for benefits. For example, if 98% of the design template remains in any given year then the benefits for that year would be calculated as 98% of the authorized benefits. The proportion remains linear throughout. Therefore, the calculation for total annual benefits of FCCE action is the summation of the FWP proportion of benefits minus the FWOP proportion of benefits discounted and annualized across all six years. This net result is an approximation of the storm damage protective capability to be provided by the restoration of the project from the end of construction until the next periodic nourishment. The benefits are expressed at the authorizing document price level of 1975, which is also what the last approved report (2016 LRR) used. It is important to note that the 1975 GDM underwent a revision in January 1976, which adjusted benefits. The revised document is the "Dade County Beaches Florida General Design Memorandum, Phases I and II" and the "Pertinent Data" section included the benefits. The structure inventory has changed significantly since 1975 in terms of both density and value so, at a minimum, benefits are assumed to still be valid. Average annual expected benefits for the authorizing document design profile are $1,675,000. The following table captures the calculation of benefits from FCCE action: 17 Dade County Beach Erosion Control and Hurricane Protection Project 20. RECOMMENDATIONS. 1 have given consideration to all significant aspects in the overall public interest, and the eligibility requirements pursuant to Engineering Regulation 500-1-1, "Emergency Employment of Army and Other Resources, CIVIL EMERGENCY MANAGEMENT PROGRAM," dated 30 September 2001. Hurricane Irma was an extraordinary storm event; however, damages to the Dade County Main Segment do not meet the eligibility criteria for rehabilitation assistance pursuant to ER 500- 1-1 paragraph 5-20.a with regard to economic justification. Therefore, I recommend no further Federal action under the Flood Control and Coastal Emergency Program. ASON A.
