St. Johns County

The ocean shoreline of St. Johns County is approximately 42 miles long. The Corps of Engineers examined opportunities to reduce the risk of coastal damage and improve conditions on approximately 9.8 miles of beach. The St. Johns County Feasibility Study area consists of 3.8 miles in South Ponte Vedra, 3.7 miles in Vilano Beach and 2.3 miles in Summer Haven. This study will define federal interest and determine if a National Economic Development Plan can be formulated. The objective of the study is to determine the feasibility of stabilizing beach areas of St. John’s County, Florida, that are threatened by erosion, reduce damages to upland development and to increase the safety of both structures and citizens.

The study and recommended plan received unanimous approval from the USACE Civil Works Review Board March 2017. The Chief of Engineers report was signed August 2017. The Chief's report will move to the Office of the Assistant Secretary of the Army for Civil Works for review. The Corps anticipates an Office of Management and Budget review in fall 2017, and when approved will move forward for congressional authorization.

St. Johns County Shoreline Feasibility Study

The U.S. Army Corps of Engineers, Jacksonville District is working on the St. Johns County, Florida. Coastal Storm Risk Management Project draft feasibility study and environmental assessment.

The study team, consisting of federal, state and local agency officials, assessed the feasibility of providing federal coastal storm risk management measures to portions of St. Johns County’s shoreline. Specific problems in the study area include storm damages due to erosion, inundation, and waves threatening infrastructure, natural habitat and recreational opportunities.

Shoreline erosion severely threatens State Road A1A, the only north-south hurricane evacuation route for communities along the coastline. SR A1A is an integral part of the county’s infrastructure and is essential for public safety prior to, during and after major storm event.

The St. Johns County shoreline is approximately 42 miles long. The Corps of Engineers examined opportunities to reduce the risk of coastal damage and improve conditions on roughly 9.8 miles of beach. The study area consisted of 3.8 miles in the South Ponte Vedra area, 3.7 miles in Vilano Beach and 2.3 miles in Summer Haven.

The selected plan design consists of a 60-foot seaward berm extension and maintenance of the existing dune along 2.6 miles, approximately from the southern end of the Serenata Beach Club to San Pelayo Court.  The Corps anticipates an initial construction and then four periodic renourishment events at about 12-year intervals.  See the fact sheet for more details.
