PDF - CMI Sheet Piling

MARINE STRUCTURES
Bay St. Louis Municipal Harbor
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.
