Construction Site Hydroseeding in New Orleans, LA

Construction site hydroseeding gets bare, graded ground in New Orleans covered fast, whether the goal is a temporary hold between phases or the final cover that lets a project close out. We work for home builders, general contractors, site work firms and property owners on subdivision lots, commercial pads, parking lot islands, detention areas, roadside shoulders and drainage swales. As hydroseeding contractors, we bring the tank, the seed and mulch, and the erosion controls that go with them.

Why cover matters on a permitted site

Federal stormwater rules require a permit once construction disturbs one acre, and smaller disturbances need one too if they fall within a "larger common plan of development or sale." Every construction stormwater permit has to meet the federal minimums: effective erosion and sediment controls, and stabilization of disturbed areas immediately once work has stopped with no restart planned within 14 days. A graded pad that will sit while the building permit, utilities or financing catch up is exactly the ground those rules target. A hydroseed or hydromulch application covers it in a day.

Temporary seeding versus final cover

Temporary cover is about holding soil for weeks or months: a quick-establishing seed mix, mulch and tackifier on stockpiles, pad edges and future phases. Final cover is the permanent grass that goes in once grading is finished and the landscape plan is set. On commercial and multi-family work, Article 23 of the city's zoning ordinance requires a landscape plan, and at least half of required landscaped area is to be built as green stormwater infrastructure. Parking lots get a detention area that may be grassed or planted. We seed to the approved plan and coordinate with the landscape installer on what is turf and what is planted.

Graded clay is hard to seed

Much of the ground here is clay. The USDA describes Sharkey soils, common in Mississippi River backswamps, as very slowly permeable with 60 to 90 percent clay below the surface. Once a dozer has smoothed and compacted that kind of soil, it sheds water like pavement. Seed sprayed on a slick clay face can sheet off in the first storm. We ask the grading crew to leave the surface rough or tracked up and down the slope, or we scarify it ourselves, and on finished areas we add a topsoil layer where the plan calls for it.

Scheduling around other trades

The right time to seed is after the last truck has crossed the area. We phase work so finished sections get cover first, keep a buffer off curbs and inlets that are still protected, and come back for areas opened by late utility work. On a long job we can seed temporary cover early and overseed with the permanent mix later. Tell us the inspection dates you are working toward.

Season and water

Rain here averages more than 63 inches a year at the airport, with June the wettest month. That helps germination but punishes bare ground. The airport's daily mean stays above 70 degrees from April through October, the stretch when warm-season seed grows quickly. Outside that window, mulch and tackifier still provide immediate cover while growth slows. Germination needs water: we need a water source on site, or we haul it, and we plan watering with your superintendent.

Why hydroseeding companies quote per acre

Large areas are priced by the acre because the truck covers ground quickly once it is set up. Consumer guides put large-area hydroseeding from about $2,000 to $4,900 per acre, and the two bids on a 2023 municipal job in North Little Rock, Arkansas were $2,595 and $3,325 per acre. Access, water hauling, mulch rate and the number of mobilizations change that. Our written estimate shows each one.

What we need from you

• Site plan or landscape plan with turf areas marked
• SWPPP or erosion control plan, if the project has one
• Areas ready now and expected phase dates
• Water source location and site access rules
