How contractors evaluate shorelines before building a bulkhead

Contractors in Louisiana assess shoreline conditions before bulkhead construction to account for soil movement, erosion, drainage, water levels and site access. The evaluation helps determine the structure’s design, installation method and ability to retain land over time.

Why it matters: - Shoreline conditions can change the design, height and installation method of a bulkhead before construction starts. - Louisiana waterfront properties face shifting water, rainfall, storms and soil conditions that can affect long-term stability. - Early evaluation can help reduce problems tied to erosion, drainage, water pressure and site access.

What happened: - Contractors typically review soil conditions, erosion patterns, water levels, drainage, existing structures and site access before building a bulkhead. - Elwin Ordoyne, vice president of E.C.O. Builders Inc. in Slidell, Louisiana, said shoreline evaluation helps determine how a bulkhead should be built. - E.C.O. Builders Inc. is based in Slidell and provides residential construction, renovation, elevation, foundation, bulkhead and related services.

The details: - Contractors often inspect visible erosion, collapsed soil, exposed roots, washouts and land movement toward the water. - Older bulkheads that lean, separate or deteriorate can signal soil pressure, drainage issues or water movement. - Shoreline shape matters, and a straight canal frontage can present different issues than a curved shoreline, irregular bank or open-water exposure. - Measurements help establish the length and configuration of the proposed structure. - Louisiana soil can include clay, sand, silt and organic material, and each type responds differently to moisture and pressure. - Soft or unstable soil can affect piling depth and overall structural design. - Soil behind the proposed bulkhead also matters because the wall must retain that material after construction. - Water pressure acts on one side of the bulkhead, while soil, groundwater and other forces act on the other. - Water levels can change with rainfall, tides, storms, drainage systems and nearby waterways. - Contractors look at typical water levels and signs of how high water may rise during changing conditions. - Bulkhead height must account for the relationship between land and water, since a structure placed too low may not retain soil during elevated water conditions. - Water depth can also affect construction access and installation methods. - Rainwater and groundwater behind the bulkhead can create pressure if drainage is not addressed. - Poor drainage can lead to hydrostatic pressure behind a retaining structure. - Contractors may review grading, downspouts, drainage ditches and paved surfaces that influence water flow across the property. - Existing docks, boat lifts, decks, fences, sheds, swimming pools and other shoreline improvements can affect construction planning. - Nearby homes and foundations may also need consideration when work occurs close to an occupied structure. - Property boundaries matter, especially where neighboring waterfront properties share portions of a shoreline. - Bulkhead construction depends on moving materials and equipment to the shoreline. - Contractors assess whether work can be done from land, from water or through a combination of methods. - Trees, fences, landscaping, utility lines, neighboring structures and narrow side yards can limit access. - Pilings, panels and other components need staging space before installation. - Erosion often prompts bulkhead planning, but contractors also study the direction of water movement to find why soil is being lost. - Boat wakes, storm runoff, tidal changes and drainage discharge can all contribute to erosion.

Between the lines: - The evaluation process is about more than the wall itself; it is about understanding the forces the wall will face after construction. - Waterfront projects in Louisiana require site-specific planning because soil, water and drainage conditions can vary sharply from one property to the next. - The more developed a lot is, the more likely access, staging and existing structures will shape the project plan.

What's next: - Contractors use the shoreline assessment to determine dimensions, materials, installation methods and other structural considerations. - Property owners can expect bulkhead planning to focus first on ground conditions, water behavior and nearby structures before any major construction begins. - On Louisiana waterfront sites, shoreline evaluation remains an early step in setting up a project that can withstand local conditions.

The bottom line: - A bulkhead may be the visible end result, but the real planning starts with what lies beneath the shoreline and around it.
