Saint Augustine Proposes Seawall Elevation and Preservation Plan to Combat Flooding

In a pivotal meeting held at St. Augustine's city hall, members of the Historic Architectural Review Board (HARB) gathered to discuss the future of the city's seawall, a crucial structure that safeguards the historic downtown area from flooding. The seawall, which has reached the end of its functional design life, is particularly vulnerable due to its location at the lowest point along the coast from Matanzas Bay. Recent images from Tropical Storm Nicole highlighted the urgent need for improvements, as water overtopped the wall and encroached upon the historic district.

The proposed design aims to enhance the seawall while adhering to the Secretary of the Interior's standards, ensuring that the historic and cultural integrity of the area is preserved. The seawall consists of five distinct sections, each constructed at different times and using various materials. The most recognizable is the Center seawall, a 740-foot structure that serves as a focal point for both residents and visitors.

During the meeting, the design team emphasized the importance of using materials that reflect St. Augustine's heritage, such as coquina, granite, and oyster tabby. They proposed raising the adjacent seawalls to a height of 10.5 feet, which aligns with the recommendations from the Army Corps of Engineers regarding storm surge elevations. This elevation is crucial for protecting the area against potential flooding from future storms.

The proposed changes include raising the North Wall by approximately 4.5 feet and the South Wall by an average of 5 feet. These adjustments are designed not only to enhance flood protection but also to maintain the aesthetic appeal of the historic site. The design team presented renderings illustrating how the new walls would integrate with the existing landscape, ensuring that the views and experiences of visitors remain intact.

As the meeting concluded, board members expressed their support for the proposed design, recognizing its potential to safeguard St. Augustine's rich history while addressing the pressing challenges posed by climate change and rising sea levels. The discussions underscored a commitment to preserving the city's unique architectural heritage while adapting to the realities of a changing environment. The future of St. Augustine's seawall now rests in the hands of the community, as they weigh the importance of historical preservation against the necessity of modern resilience.
