MONITORING REPORT
MIDTOWN BEACH NOURISHMENT PROJECT
IN PALM BEACH, FLORIDA
October 1995 to August 1996
INTRODUCTION
During the period October 18, 1995 to December 10, 1994, approximately 880,000 cubic yards of
sand were dredged from a borrow area extending from approximately 2,000 feet south to 4,800 feet
south of the south jetty at Lake Worth Entrance and placed along portions of Midtown Beach section
in the Town of Palm Beach, Florida. As shown in Figure 1, the cross-shore dimensions of the borrow
area varied from 1,600 feet at its northern end to 2,500 feet at its southern end. The original depths
at the borrow area site varied from 25 to 35 feet and the dredged depths were approximately 40 feet
deep. The dredged sand was placed along the Midtown Beach as nourishment extending from via
Bethesda at the north end to via Marina at the south end, a distance of approximately 5,030 feet. To
provide stability to the nourishment project, eleven groins were constructed. The locations of these
groins are shown in Figure 1 along with the borrow area and the approximate planform of the
nourished beach. Sea Systems, Inc has conducted a pre-nourishment and two post-nourishment
surveys to document the performance of the project. The purpose of this report is to present the
results of an analysis of these three surveys.
The dates of the surveys are presented in Table 1. As can be seen from Table 1, although the
placement of material was completed in December, the first post-nourishment survey was not
completed until April 9, 1996 due to the activities related to groin construction. During the period
between completion of nourishment and the first post-nourishment survey, a significant northeaster
occurred (March 8-10, 1996) which undoubtedly caused the transport of some sand from the
nourished beach. Thus, since the first post-nourishment survey post dated the March storm, this
survey does not reflect the total amount of sand placed.

RESULTS
The results are presented in various forms, including examples of beach profiles, longshore
distribution of additional volumes as a function of time, longshore distribution of additional beach
width as a function of time and total additional areas and volumes as functions of time.
Beach Profiles
Figures 2 and 3 present examples of the available beach profiles in the borrow area and in the
nourishment area, respectively. All of the profile surveys are presented in Appendix A. Figure 2,
representing the profiles at DNR Monument R-79 is located approximately 3300 feet south of the
south jetty. It is seen that the pre-nourishment depths in the borrow area ranged from approximately
25 feet to 35 feet and that the post-nourishment depths are approximately 40 feet. Figure 3 depicts
the pre- and post-nourished profiles at Monument R-97D129 which is located at approximately mid-
length of the nourishment project. This is in an area where the shoreline revetment is located and
prior to the nourishment, there was no beach at mean tide as the water was at the revetment. After
nourishment, there was approximately 150 feet of additional dry beach present. The presence of the
natural offshore reef extending from 700 feet to 1,200 feet from the seawall is evident. Also evident
from this plot is that there was very little change from the April post-nourishment survey to the
August post-nourishment survey. As will be evident later, there were only minor changes in both
volume and dry beach area within the longshore extent of the project during this period.
Longshore Distributions of Volume Densities and Plan Areas
Figure 4 presents the longshore distribution of additional volume density along the project area. It
is seen that on average, 150 cubic yards per foot of beach front were present in April 1996 along
the 5,030 feet of project area. Note also that between the April 1995 and October 1995 surveys,
although there has been some redistribution of volume, there has been very little volume loss. The
volume densities in Figure 4 represent the volumes to approximately 1,000 feet seaward from the
monument. As can be seen by referring to Figure 3 and the figures in Appendix A, this distance
extends out onto the natural reef.
Figure 5 presents the longshore distribution of additional beach width within the project area as was
presented for volume density. Substantial similarities exist between the volume densities and
additional beach widths. The changes between the April and August surveys are relatively small.

Changes in Total Volumes and Plan Areas
Table 2 shows the total changes in volumes and plan areas from the pre-nourishment survey to the
two post-nourishment surveys.

October 1995 to April 1996 +795,340* (+751,697) +16.61* (+17.6)
October 1995 to August 1996 +791,170' (+747,521) +16.65* (+17.2)
*Notes: These changes are from Monument R-94I to R-100C, a longshore distance of 6,100 feet.
The numbers in parentheses represent the changes over the 5,030 feet constructed Project
length.
SUMMARY AND CONCLUSIONS
Based on the two post-nourishment surveys, the Midtown Beach project has performed quite well,
generally maintaining the volume and plan area from the first post-nourishment survey to the second.
Although the post-nourishment period available and analyzed in this report is for a generally mild
weather period, the small volume and planform area changes are better than one might expect. Even
accepting the reported placement volume of 880,000 cubic yards, the maximum loss which is to
August 1996 within the placement area is approximately 15%. Moreover, most of this apparently
occurred during the period when the groins were not in place and during the intense March 1996
storm. The next post-nourishment survey has been authorized and the changes during the 1996-1997
winter season will provide a more complete understanding of the expected performance of the
project over an entire year of wave activity.
