Soft ground under most New Orleans lots compresses under new weight. We remove the worst soil where the plans say to, place fill in thin compacted layers and grade the lot toward the street.
Site prep in New Orleans is about building on soft ground. Under most lots lies clay and organic soil that compresses when weight goes on it, so a pad that is not built right will settle unevenly. We strip the topsoil and roots, remove soft or organic pockets where the plans call for it, and place fill in thin, compacted lifts. On many sites, the engineer calls for a set amount of fill and time for it to settle before building.
Grading here has one job: get water to the street. The city and the parishes pump rain out through drains and canals, and a lot that does not slope to the street or a drainage servitude will hold water after every storm. We set the finished grade so the ground falls away from the house, and we make sure new fill does not send water onto the neighbors.
Mud has to stay out of the storm drains, which clog fast in this flat city. Silt fence, inlet protection and a stabilized entrance keep it on the lot. Under LDEQ rules, a project that disturbs one acre or more needs construction stormwater coverage, with a written pollution prevention plan in place before work starts. Below one acre, LDEQ does not regulate the site, but the city still expects a clean street.
Site prep & grading in New Orleans: common questions
Can you raise my lot with fill?
Often, yes, with compacted fill placed in layers. The city or parish may have rules on fill and elevation, and new fill must not push water onto neighbors.
Why does fill settle so much here?
The soft clay and organic soil under most lots compress under new weight. Thin, compacted lifts and time to settle reduce it.
How long after rain can you grade?
Soft, wet ground needs to drain and firm up first. We watch the forecast and the ground before scheduling.
