MONITORING REPORT
MIDTOWN BEACH NOURISHMENT PROJECT
IN PALM BEACH, FLORIDA
October 1995 to April 1997
INTRODUCTION
During the period October 18, 1995 to December 10, 1995, 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. The project specifications required placement of 800,000 cubic
yards; thus the excess 80,000 cubic yards is "overfill". 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 three 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 four 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, the first
post-nourishment 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 range up to 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; however, there was a somewhat
greater change from August 1996 to April 1997. 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 the
April 1996 to August 1996 period, but substantially greater changes from August 1996 to April
1997.
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, an additional 150 cubic yards per foot of beach front were present in April
1996 along the 5,030 feet of project area. Between the April 1996 and October 1996 surveys,
although there had been some redistribution of volume, there had been very little volume loss.
Between August 1996 and April 1997, the losses have been considerably greater. 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 in a
form similar to that 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; however, the changes from August 1996 to April 1997 are greater.

SUMMARY AND CONCLUSIONS
Based on the three 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
and third surveys. The first five month post-nourishment period (April 1996 to August 1996) is for
a generally mild weather period whereas the second seven month post-nourishment period (August
1996 to April 1997) is for a more generally energetic wave period. The area and volume changes
reflect the wave energy levels of these periods. Accepting the reported placement volume of 880,000
cubic yards, the maximum loss to April 1997 within the placement area is approximately 31%.
Moreover, approximately one-half of this loss occurred during the period when the groins were not
in place and during the intense March 1996 storm. The losses during the seven month winter period,
August 1996 to April 1997 within the placement area represent approximately 15.9 % of the material
placed. The total losses during the one year period April 1996 to April 1997 within the placement
area may represent the losses to be expected during a typical first year after nourishment and amount
to 16.3 %.The total losses within the surveyed area during this one-year period are 6.3 %.
Nourishment losses are expected to decrease as the effective length of the project becomes greater
due to spreading of sand from the nourishment area. Additionally, at the Midtown Project, the
stabilizing effects of the groins should start to occur soon. Two final points are relevant to evaluating
project performance: (1) The project performance to date reflects two winter seasons. Very little
change appears to occur during the summer months, and (2) Since permit conditions require
renourishment when 40% of the project volume has been transported from the placement area, this
would occur when the volume remaining is 480,000 cubic yards.
