EXECUTIVE SUMMARY

A study has been carried out to determine the erosion rates in Brevard County, Florida and to apply those rates to the projection of existing flood zones a landward distance equivalent to 60 years of the erosion trend. The results are provided on a series of 78 aerial photographs at a scale of 1: 5000. Each photograph is annotated to show the 60 year projected shoreline and the 60 year projected V-zone/Azone boundaries and the associated gutter lines.
The shoreline changes were based on a shoreline position data base developed and maintained by the Bureau of Beaches and Coastal Systems (BBCS) of the Florida Department of Environmental Protection (FDEP). The individual data points are located at nominal shoreline spacings of 1,000 feet and include data from 1875 to 1997. These shoreline position data were analyzed by three methods and for two different time periods. Although it was found that all three methods resulted in similar rates, two of the methods (least squares and end point methods) were in better mutual agreement than the third (Foster-Savage Method) and based partly on this comparison, a decision was made to apply the least squares method in this study. The two time periods analyzed were the total period of data availability (1875 to 1997) and the more recent period of 1928 to 1997. The shoreline change rates were reasonably similar for these two periods and it was decided to apply rates for the more recent period in order to emphasize current trends. The average shoreline change rates in Brevard County are very small; however, there is a wide range of local shoreline change rates with the maximum local recession and advancement rates for the more recent period approximately 6.6 feet per year and 16.9 feet per year, respectively. Although the shoreline position data base is based on the locations of the Mean High Water (MHW), the reference elevation employed by the State of Florida for regulatory purposes is the so-called Seasonal High Water Elevation (SHWE) which is at an elevation of 1.5 times the mean tidal range above the Mean High Water Elevation (MITWE). The rationale for the SHWE is that its higher position on the profile than that of MHW should result in a location that responds more like the long term shoreline change rate and less to individual storms and seasonal fluctuations.
With the aerial photographs, the Flood Insurance Rate Maps (FIRMs) and the long term erosion rates available, the annotated aerial photographs were prepared for the 72 mile shoreline of Brevard County. This entailed plotting the following information on the base maps: (1) The projected 60 year position of the SITWE (in those cases where the shoreline was stable or advancing, the shoreline was not projected), (2) The current flood hazard lines as transferred from Flood Insurance Rate Maps (FIRMS), and (3) The flood hazard lines projected landward by 60 years of the erosion rate at those shoreline locations where long term erosion existed.




PROJECTED FLOOD HAZARD LINES
FOR BREVARD COUNTY, FLORIDA
INTRODUCTION
The Federal Emergency Management Administration (FEMA) is charged with the assessment of a wide range of hazards and with developing and implementing measures to achieve long term risk reduction for these hazards. Coastal areas are subject to hazards due to flooding and damage due to extreme storms and in some areas, tsunamis. In Florida, coastal hazards are the result of tropical and extra-tropical storms. In such areas, FEMA is responsible for a program in which numerical modeling is carried out using the historic meteorological data base and the bathymetry of the area of concern to establish extreme storm surges and the associated waves. This information is provided in the form of charts or maps with the hazard zones drawn as isolines denoting the elevations for lower structural members. These charts, denoted Flood Insurance Rate Maps (FIRMs), are available for most coastal areas in the United States. In coastal areas with substantial erosion rates, the higher hazard zones will gradually be translated landward in the future unless shoreline stabilization measures are implemented. There is merit in recognizing these encroaching hazards in the management considerations and actions associated with these hazards. FEMA is currently evaluating economic and other impacts of considering the effects of progressive erosion in the hazard mapping and management process. This requires the landward projection of hazard areas based on appropriate local erosion rates. This report presents the results of one such pilot mapping effort for Brevard County, Florida to determine the long term erosion rates and to project landward the existing flood hazard zones in accordance with the long term erosion rates.
THE SETTING
Brevard County is located on the middle east coast of Florida and consists of a coastal barrier island separated from the mainland by Mosquito Lagoon, Indian River and Banana River, extending over a length of approximately 72 miles, see Figure 1. Between Port Canaveral and Sebastian Inlet, where FDEP has surveyed beach profiles, the beaches are generally narrow and the dune elevations vary between 9 to 25 feet above NGVD. Brevard County is subject to hurricanes with the 100 year storm tide on the order of 11 ft. As is the case for many coastal counties in Florida, the shoreline change rates averaged over the entire county are small; however, at any particular shoreline location, the long-term shoreline change rates can deviate substantially from the County average. As an example, the shoreline change rates for the period 1928 to 1997 range from recession of approximately 6.6 feet per year to advancement of 16.9 feet per year.
PROCEDURES
The procedures applied may be considered in three steps. The first step required the determination of the long term shoreline change rates. For this purpose, use was made of the excellent shoreline

position data base developed and maintained by the Bureau of Beaches and Coastal Systems (BBCS) of the Florida Department of Environmental Protection (FDEP). These data extend from the mid1870's to 1997. Five dates are available for the V-series monuments, which are located north of Cape Canaveral and generally for the monuments between Port Canaveral and Sebastian Inlet, data are available for between ten and twelve dates, with most of the data availability after the 1930's. The second step required the transfer of the existing flood hazard lines on a set of aerial photographs at a scale of 1:5,000. The third and final step was the translation of these lines by a distance equal to 60 years of the long term erosion rate.
RESULTS
Shoreline Change Rates
The FDEP shoreline position data base consists of shoreline positions at locations of fixed monuments along the shoreline. The spacing of these monuments is nominally 1000 feet and the monuments were first installed in Brevard County in August 1972. The 72 mile shoreline is represented by a total of 389 monuments of which 168 monuments are V-series ("Virtual", i.e. no physical monuments present) and the remaining 221 monuments are initially the R-series. Shoreline position data are available for Brevard County for the period 1875 to 1997, a 122 year period. The shoreline positions in the FDEP data base are distances from a known monument location to the Mean High Water Line position. To evaluate the long term rates, three analysis methods were applied to the available data. These included: (1) the least squares method, (2) the method developed by Foster and Savage (1989), and (3) the end point method. The analysis of data was applied to the full set of data (1875-1997) and to a more recent time period (1928-1997). The results for these two time periods are presented in Figures 2 and 3. Referring to Figure 2 for the total period for which data are available, it is seen that in general, the three methods are in reasonable agreement; however, the Foster-Savage method (described in Appendix A) tends to predict more extreme shoreline change rates at some locations when compared to results from the other two methods. Referring to Figure 3 and comparing the results, the general observations and comments are similar. In order to intercompare the shoreline change results on a quantitative basis, the correlation coefficients were developed for the three methods with the results presented in Table 1. On the basis of the results in Table 1 and those in Figures 2 and 3, it was decided to utilize the results based on the least squares approach.

Although Figures 2 and 3 provide the local shoreline change rates, it may be useful to examine the results of the shoreline change analysis in different forms. The total average long and shorter shoreline change values for the entire county are +1.35 and +1.34 feet/year, respectively for the two time periods based on the least squares method. Figures 4 and 5 present histograms of shoreline change rates based on the longer (1875 to 1997) and shorter (1928 to 1997) periods, respectively. A substantial beach nourishment project was placed in 1974 south of the Port Canaveral Entrance to counter erosional trends caused by this entrance which was constructed in 195 1. A second substantial nourishment is planned in the same approximate location in the next year or two. These nourishments appear to approximately offset the deleterious effects of this entrance and thus are not recognized explicitly in modification of the erosion rates. These shoreline protection structures (armoring) in Brevard county are limited in number, individual length and survival capacity during a major storm. Thus, shoreline change rates used in projecting the hazard zones were not modified for the presence of shore protection structures.
Aerial Photographs With Projected Flood Hazard Lines
A complete set of aerial photographs was prepared for Brevard County with the hazard lines projected 60 years into the future based on the long term erosion rates as determined by the least squares method and as shown in Figure 3. A five point smoothing filter was applied to the erosion rates prior to their application to projecting the hazard lines. Additionally, at some locations, limited subjective smoothing was conducted. The set consists of 78 aerial photographs with each photograph representing approximately 1.2 miles. The FDEP monuments are indicated on each aerial photograph. To provide references of the photographs to a standard system, the latitudes and longitudes associated with each of the FDEP monuments are presented in Appendix B. These monuments are numbered sequentially with Monument V-001 located at the Northern County boundary and Monument R-219 located at the Southern County line. The original "gutter lines" are

indicated by solid lines with each color designating a particular gutter line. The dashed lines indicate the gutter lines projected by the 60 years of shoreline recession. For those areas with a long term advancement trend, the gutter lines were not shifted. Figure 6 presents an example aerial photograph and will be used to describe the series. The code used for interpretation of the lines on the aerial photographs is provided on each photograph as shown in Figure 6. Figure 6 is located approximately one-fifth of the distance from Port Canaveral to Sebastian Inlet. Figure 6 encompasses approximately 5000 feet of beach fronting the Atlantic Ocean. Referring to Figure 6, it is seen that Monument "R-3 8" is located near the northern part of the photo and Monument "R-41IT" is located near the southern part of the photograph. The solid black line is the 60-year projected position of the solid green SHWvL line. The solid and dashed red lines correspond to current and projected 16 feet flood hazard lines; the solid green line also corresponds to the current 13 feet flood hazard line with its projected line indicated by the solid black line. The localized solid and dashed light blue lines correspond to the current and projected one foot depth flood hazard lines, which is located between monuments R-3 8 and R-3 9.
SUMMARY AND CONCLUSIONS
This study has developed the long term shoreline change rates for Brevard County, Florida and applied these rates by displacing the flood hazard lines landward by 60 years of the erosional trend. Two periods were considered in developing the erosion rates: (1) The full 122 year period of shoreline availability (1875 to 1997) and, (2) the most recent 69 year period (1928 to 1997). Additionally three different methods for determining the shoreline changes from the available data were applied and intercompared. Based on examination of the results, the least squares results based on the shorter time period were applied to the displacement of the flood lines. Although, on average, the long term shoreline change trend in Brevard County is small, the deviations from the County average are large ranging from a local erosional trend of approximately 6.6 feet per year to advancement of 16.9 feet per year. These are limited shoreline protection structures in Brevard county. The effects of these structures were not recognized in translating the hazard lines.
The results are presented as a series of 78 aerial photographs at a scale of 1:5,000. Each photograph is annotated with the positions of the shoreline projected to represent 60 years of the erosional trend, the current flood hazard lines and the flood hazard lines projected by 60 years of erosional trend. In areas where the shoreline trend is neutral or advancing, there are no projected shorelines nor projected flood hazard lines.

DESCRIPTION OF THE THREE METHODS APPLIED TO DETERMINE
LONG TERM SHORELINE CHANGE RATES




APPENDIX A

DESCRIPTION OF THE THREE METHODS APPLIED TO DETERMINE LONG TERM SHORELINE CHANGE RATES
INTRODUCTION
The three methods used to determine long term shoreline change rates include: (1) The least squares method, (2) The method developed by Foster and Savage, and (3) The end point method. For purposes of completeness in this report, each of these three methods is described briefly below.
DESCRIPTION OF THE THREE METHODS
The three methods employed in the analysis herein are described below.
(1) The Least Squares Method
The least squares method is a formal procedure which establishes the "best fit" of an analytical relationship to a set of data. In the application here the analytical relationship is a straight line with two unknowns and thus requires at least two data points. If only two data points were available, the fit of the straight line to the data points would be exact and would be the same as the "end point" method. In the case in which there are more data points than free parameters in the analytical relationship, the method minimizes the sum of squares of the deviations between the data points and the analytical relationship. The method of least squares is described in many references and is commonly available as a subroutine in software packages.
(2) Method of Foster and Savage
This method was developed and proposed by Foster and Savage (1989) and provides a rational basis for taking into consideration the accuracies of the individual data points and the spacing of the data points in time. Basically, the method averages those possible end point rates that qualify based on consideration of the magnitude of the difference in shoreline position being realistic, ie not simply the result of errors in the data. Defining E, and E2 as errors in data at times tj and t2 respectively, the criterion for deten-nining the rate is that the minimum time between data points to be considered is




in which E, and E2 are the errors associated with the data at times t1 and t2, respectively and R1 is the end point rate for the location of interest. The average end point rate is then taken to be the average of all end point rates which satisfy' the above criterion. It is noted that for N available data points, there are N(N- 1)/2 possible combinations. For example, if there are 7 data points, there are 21 possible combinations of pairs of points that could yield valid end point rates if they all satisfied the above equation.
(3) End Point Method
This is the most simple method of the three and involves the calculation of the rate based on the first and last data points.
