Krebs, LaSalle, LeMieux is dedicated to assessing and developing methods to control or minimise the harmful effects of human activity on the environment. It is fundamental that the impact on the environment is taken into consideration when development projects are carried out. This ensures the sustainability of our way of life and the surrounding natural environment.
Wetland delineation is simply the act of establishing the boundary between wetlands and uplands (or non-wetlands). There are two delineation procedures developed at the federal level and several states have their own wetland delineation procedures.
Wetland is determined through data collection at the site to simply determine whether an area is a wetland.
For landowners who want to protect the natural resources on their property, just knowing that a wetland exists may be enough information for a hands-off form of stewardship. However, if you want to develop the property, determining whether the property is wetland or the land adjacent to your is wetland might impact the wetland's functions (or is a regulated activity). Knowing the wetland boundaries is essential.
Site construction activity often requires excavation and/or discharge of dredged or fill material in waters of the U.S. The federal Clean Water Act (CWA) was written to protect and restore the quality of the United State's surface waters. To help in attaining this goal, filling, grading, mechanized land clearing, ditching, other excavation activity, and piling installation in waters of the U.S. require a U.S. Army Corps of Engineers Section 404 Permit prior to the commencement of construction.
Section 10 of the Rivers and Harbors Act of 1899 requires that regulated activities conducted below the Ordinary High Water (OHW) elevation of navigable waters of the United States be approved/permitted by the U.S. Army Corps of Engineers. Regulated activities include the placement/removal of structures, work involving dredging, disposal of dredged material, filling, excavation, or any other disturbance of soils/sediments or modification of a navigable waterway. Navigable waters of the United States are those waters of the U.S. that are subject to the ebb and flow of the tide shoreward to the mean high water mark and/or are presently used, or have been used in the past or may be susceptible to use to transport interstate or foreign commerce [see attached list]. Navigable waters of the U.S. are not necessarily the same as state navigable waterways. Tributaries and backwater areas associated with navigable waters of the U.S., and located below the OHW elevation of the adjacent navigable waterway, are also regulated under Section 10.
Environmental mitigation is the process of addressing damage to the environment caused by land development, transportation or other public works projects. Actions taken to avoid or minimize environmental damage are considered the most preferable method of mitigation.
Potential environmental mitigation activities may include:
Krebs, La Salle engages in several layers of Mitigation Consultation including but not limited to:
Federal Agencies prepare Environmental Assessments for proposed actions in accordance with NEPA regulations. An Environmental Assessments analyzes the environmental effects of a proposed activity to determine the significance of potential impacts. Any significant impacts identified in an Environmental Assessments must be analyzed in an Environmental Impact Study. An Environmental Assessments also documents the potential environmental impacts of proposals that do not require an Environmental Impact Study, and identifies as early as possible mitigation measures.
We assume that the proposal evaluated in an Environmental Assessments includes mitigation required by lease stipulations, regulations, other Federal and State environmental laws, and specific measures committed to in writing by the lessee, operator, or applicant prior to completion of the Environmental Assessments. Mitigation measures not identified in the proposal may be evaluated in the Environmental Assessments to determine whether such measures, if approved as part of the proposal, would reduce impacts to a less-than-significant level.
Foundation design and civil engineering services include the analysis, design, and preparation of construction plans for a variety of structures. Types of foundations include: Spread footings, driven timber foundation piles, pier foundations, drilled shaft foundations, sheet pile walls (cantilevered and anchored), T-walls, retaining walls, mat foundations, and ribbed slab foundations.
We design roadways knowing that a properly designed and constructed road provides a means of getting from one point to another in a safe and efficient manner. We also know that roadway location, design, and construction can greatly affect people and property in direct and indirect ways. While proper access to and through a piece of property is essential, a road design must address the impacts on the property owner and the property. The cost of construction of a subdivision roadway can be enormous, but the value of maintaining marketable natural landscape is priceless. Krebs, LaSalle, LeMieux utilizes the accumulation of field data and testing with years of road design experience to serve our clients' needs. We understand the fundamental principles of good road design is critical to existing or future properties to prevent an existing roadway from becoming obsolete. In designing roads, our engineering and land surveying team addresses safety issues, regulatory requirements, stormwater management, and economic value.Whether a project involves a state highway, town road, private road, subdivision or driveway, a client wants the road designed and built properly. Krebs, LaSalle, LeMieux provides plan detail and specificity, in addition to professional support, to assure that the road design will be clearly understood and implemented as intended. Our staff has experience with road design conditions throughout the Gulf South region.
Flood protection levees are barriers that holds water away from property. It can protect your property from flooding as well as from the force of water, scour at the foundation and impacts of floating debris.
A properly built levee takes a lot of space. Its sheer mass keeps it from moving. Long, gentle side slopes increase stability and provide for easier maintenance. A typical levee 3 feet high should be 21 feet wide. If the inner edge is 4 feet from the building, its outer edge will be 25 feet from the building.
