Figure 3. Post-fill March 1995 and 2 years later April 1997 at Sea Gate hot spot
being monitored. The project is divided into two sections with Section I extending from Sea Bright
to Ocean Township (Loch Arbour) and Section II extending from Asbury Park to Manasquan.
Section I has four reaches, one of which has not been constructed yet and Section II has two reaches
(Table 3). Figure 4 shows the complex sequence of construction and the location of the project's
three hot spots: (a) at Monmouth Beach, (b) at Spring Lake, and (c) the south end of the Sandy Hook
spit at Sea Bright.

Hot spot 1 at Monmouth Beach was located at the southern boundary of the first contract reach and
covered a 793-m (2,600-ft) section of contract area. The initial fill was placed in November 1994
with 396,827 cu m (519,000 cu yd) placed. To mitigate for the erosion experienced at this hot spot, a
second placement occurred in November 1995 with 175,858 cu m (230,000 cu yd) placed. A third
placement was needed in May 1998 with 431,234 cu m (564,000 cu yd) of fill placed. Through
monitoring and analysis it was determined that the cause was seaward perturbation of the beach due
to encroachment of the upland structures onto the beach and the design requirement of a uniform
