Is the current construction taking place the only option that was considered?

The City of St. Augustine explored multiple options for the restoration or new construction of the seawall south of the Bridge of Lions since 2002 and narrowed it down to four alternatives after much public comment and expert consultation:

  • Do nothing: This would have left the historic seawall as is, but the wall was not structurally sound and could collapse during a hurricane or other major storm. It also is not high enough to prevent flooding during Category 1 storms; the top of the seawall is at 6.4 feet while water elevation during such a storm, is 7.4 feet.
  • Rehabilitate the existing seawall: Structural rehabilitation of the historic seawall would have included drilling vertically into the wall, inserting stainless steel rods along the length of the wall, and tying the back of the seawall with stainless steel rods secured to a concrete anchor or “dead-man” on land. However, coquina is brittle and drilling could have damaged the original wall, and the wall is not high enough to prevent flooding during a Category 1 storm.
  • Construct a new seawall four feet seaward: The new seawall would have been built four feet seaward from the existing wall with a 7.7-foot elevation to prevent flooding during Category 1 storms. It would help preserve the historic seawall by shielding it from storm damage, but it would have had a negative effect on the wall’s pavers and foundation.
  • Construct a new seawall 10 feet seaward: Construct the new seawall ten feet east of the existing wall with a 7.7-foot elevation to preserve the wall’s structure.

Decision to Construct the New Seawall

The decision to construct the new seawall 12 feet from the original seawall was made after City Archaeologist Carl Halbirt found coquina pavers at the base of the original seawall extending ten feet from the base. The pavers had been covered by silt and oyster beds and had disappeared into shoreline muck over the course of a century. Constructing the wall a dozen feet onward means that the pavers, which are an integral part of the historic wall, could be preserved.
