When flood events or urgent conditions occur, LASS can support owners with rapid-response services and temporary works aimed at stabilizing conditions and protecting critical assets.

Typical emergency and temporary scopes may include:

- Temporary levees, berms, or barriers.
- Temporary bypasses or diversions for drainage and flows.
- Erosion protection and stabilization measures in response to storm damage.
- Other short-term measures as authorized by the owner and coordinating agencies.

We constructs and improves levees and flood control systems that protect communities from high-water events. Our work includes levee raising, embankment construction, erosion control, and associated drainage structures.

We focus on:

- Maintaining design elevations and cross-sections through strict survey control.
- Coordinating with owners, engineers, and inspectors throughout construction.
- Implementing erosion control and stabilization measures to support long-term performance.

LASS builds storm sewer networks and drainage systems designed to move stormwater safely and efficiently. Our experience covers urban, industrial, and flood-prone environments.

Typical scopes include:

- Installation of storm sewer pipe, inlets, manholes, and junction boxes.
- Construction of outfalls, headwalls, and related concrete structures.
- Work within existing corridors, easements, and active facilities with careful phasing and traffic or operations control.

We self-performs earthwork and mass excavation using experienced crews and modern equipment. We manage cut-and-fill operations, embankments, and grading activities with a focus on safety, schedule, and quality.

Our capabilities include:

- Large-scale excavation and embankment construction.
- Fine grading to meet design elevations and drainage requirements.
- Use of GPS-guided equipment and survey control to maintain accuracy and efficiency.

LASS delivers levee improvement projects that increase flood protection while keeping systems in service.
Typical work includes:
- Earthwork to raise, widen, and regrade levees to meet design elevations.
- Seepage and drainage controls, including trenches and relief features as required.
- Construction or improvement of access roads, berms, and slope protection along the levee.
We focus on quality, safety, and phasing so flood protection is maintained during construction.

Our team provides erosion protection that stabilizes banks, levee slopes, and drainage channels and reduces maintenance costs.
Our services include:
- Slope protection for levees, channels, ditches, and ponds with rock, concrete, or other armoring.
- Geotextiles, erosion blankets, and related materials as part of engineered systems.
- Repair of eroded areas to restore sections, capacity, and stability.
We work with engineers and owners to match solutions to site conditions, rules, and budget.
