The south jetty extension began in June 1970 and was completed
in August 1970, at a cost of $12,260. Biendorf and Associates handled
this jetty extension project.
In 1971, Sebastian Inlet State Recreation Area opened to the public. The 578.3-acre park had 14,800 feet of shoreline on the Atlantic Ocean, 104,000 feet of inlet shoreline and 17,000 feet of shoreline on the Indian River.
Between April 1-July 10, 1972, a new 37 acre sand trap was dredged by Trans-State Dredging Company of Ft. Pierce, FL. A total of 425,000 cubic yards of material were dredged and placed on the southern beach. This project cost $228,000. Riprap was placed along the southern bank of the inlet, to the west of Henry's Rock. Between September and November of this year, beach profiles were taken in Brevard County to aid in the determination of the location for a coastal construction setback line. Indian River County had similar beach profiles done in November and December of 1972.
Between July 1972 and January 1973, an estimated 110,000 cubic yards of sand were deposited in the sand trap.
Between October 16-29, 1973 Tropical Storm Gilda passed several hundred miles east of the Sebastian area but caused extensive damage to Volusia and Brevard Counties. Tides were 4-6 feet above normal and the beaches at Melbourne Beach were closed to the public to prevent injuries from falling seawalls and other hazards. During the month of November, 33 coastal construction setback profile lines in Brevard County, along with 17 in Indian River County, were resurveyed. Results showed beach and dune erosion from 5-25 feet horizontally.
A 1973 coastal zone map series (also known as T-sheets) was compiled and published by the National Ocean Survey (C&GS) in cooperation with the State of Florida, Department of Natural Resources. The map series was intended for planning purposes and as source data for selecting baseline points to establish seaward boundaries. Relevant maps to this study area include:
TP 00145,
Brevard County, FL: Fisherman Point to Malabar;
TP 00149,
Brevard and Indian River Counties, Florida: Ballard Cove to Sebastian
Creek;
TP 00151,
Brevard and Indian River Counties, FL: Black Point to Wabasso; and
TP 00152,
Indian River County, FL: Wabasso to Gifford Cut.
Tropical Storm Dottie, August 18-21, 1976
Hurricane David, August 25-September 8, 1979, Category 5
Hurricane Barry, August 23-29, 1983, Category 1
Tropical Storm Isidore, September 25-October 1, 1984
Hurricane Bob, July 21-26, 1985, Category 1
Tropical Storm Chris, August 21-30, 1988
Tropical Storm Keith, November 17-26, 1988
Hurricane Andrew, August 16-28, 1992, Category 5. Also in 1992, an experimental flame-sprayed zinc coating was applied to the seaward-most pilings, in an attempt to slow down the rebar corrosion.
Hurricane Gordon, November 8-21, 1994, Category 1
Hurricane Erin, July 31-August 6, 1995, Category 1. In August of 1995, the Sebastian Inlet Tax District commissioned Florida Institute of Technology to perform a complete photographic inspection of the interior concrete pile crib structure of the north jetty. This photo-documentation provides a baseline to measure deterioration of the jetty and will help to determine rehabilitative measures. These photos are selected from the database.
Hurricane Bertha, July 5-17, 1996, Category 3
Hurricane Irene, October 10-16, 1999
