Dallas K, Berry M, Ruggiero P. 2013. Inventory of coastal engineering projects in Fort Matanzas National Monument. Natural Resource Technical Report. NPS/NRSS/GRD/NRTR—2013/703. National Park Service. Fort Collins, Colorado
This report includes information on coastal engineering projects identified in, or immediately adjacent to, Fort Matanzas National Monument (FOMA). The report serves as a supplement to a Geographic Information Systems (GIS) database (the GIS data are available online at http://irma.nps.gov). Twenty-nine coastal engineering projects were identified in and adjacent to FOMA. Of this total, 22 are coastal structures that together extend 4,660 m (15,290 ft). Three dredging projects removed a minimum of 3,299,000 m3 (4,314,930 yd3) of sediment from around FOMA between 1932 and 2007, while four fill projects placed an unknown volume of material on Rattlesnake Island between 1936 and 1977. In addition, beach nourishment approximately 16 km (10 mi) north of the park has placed nearly 6,000,000 m3 (7,847,700 yd3) since 1963. The Matanzas River Relocation Cut and coastal structures on Rattlesnake Island have altered the natural hydrodynamics of the Matanzas River system. More than 382,280 m3 (500,000 yd3) of sand dredged for the Relocation Cut was placed on the island and nearby marsh, transforming the island. In addition, the Cut caused alterations in current velocity that has resulted in shoaling at the northern end of Rattlesnake Island.
