BACKGROUND

Situated on the Gulf of Mexico, Bay St. Louis is home to

more than 10,000 people. The city offers pristine beaches, a

pedestrian bridge with an art walk, restaurants, shops and

beautiful water views. Like several other Gulf Coast cities, Bay

St. Louis, MS experienced extensive damage after Hurricane

Katrina. Once recovery efforts were underway, the city put

together a local business group, the Bay Area Recovery Team,

to find opportunities that would enhance the visitor and

citizen experience. After assessing various options, the team

decided that a new downtown harbor would be the biggest

asset to the city. The new harbor creates a waterfront gateway

for the Bay St. Louis downtown and the harbor is connected

to a recreational fishing pier. The downtown boulevard

provides access for both tourists and residents to the new

development.

PROJECT SCOPE

After Hurricane Katrina devastated its waterfront and

downtown area, the city of Bay St. Louis, MS. embarked upon

a multi-year municipal harbor and pier project designed

to spur economic development and increase tourism. The

project includes four piers with room for a fifth, approximately

168 boat slips, a fuel dock, convenience pavilion, parking,

restrooms and a harbor master facility. Thousands of feet of

ShoreGuard® vinyl sheet piling was used for the project.

PERFORMANCE

Unlike traditional construction materials such as wood or

steel, ShoreGuard® is corrosion-resistant, UV-resistant and

impervious to marine worm damage. Vinyl sheet piling is also

lightweight and easy to install, saving time and money on-site.

CONSTRUCTION

The design included approximately 1,100 linear feet of CMI’s

22-foot ShoreGuard® 950 vinyl sheet pile, which was used

as a breakwater on the North side (lee side) of the new

harbor. Though a thinner ShoreGuard® profile was originally

specified, the SG 950 was ultimately selected for its high

design strength, durability, performance and sustainability. In

addition to providing extra structural support, ShoreGuard®

incorporates the company’s patented I-Beam Lock Technology,

which enhances the lock integrity and seam reliability of

the sheets.
