Concrete foundation contractors in Edgewater start with the flood zone
Footing size can wait. First, find out which flood zone your Edgewater lot is in. Check FEMA's flood layer at 61 spots across the city and you get 67.2 percent in Zone X, 27.9 percent in Zone A, 1.6 percent in Zone AE and the rest in shaded X. Zone A is the sneaky one, because FEMA publishes no base flood elevation for it. The AE spots showed a base flood elevation of 5 feet.
The city's Build Responsibly page says new residential construction in a special flood hazard area sits one foot above base flood elevation. It also says any development in a floodplain needs a permit, fill dirt included. That means the slab height on your plans may not be the number you figured. We walk the lot with you and ask the Building Division which elevation governs your parcel. Then we price the job off the answer. Land along the Indian River Lagoon needs extra care. Edgewater itself warns that land there floods more easily from heavy rain, high tide and tropical storms.
Wet flatwoods sand and muck pockets under Edgewater slabs
Soil here changes fast. About a third of those same 61 spots sat on Myakka, Smyrna and Immokalee fine sands, all poorly drained. Muck soils (Tequesta, Samsula and Gator) turned up at close to 10 percent. Daytona sand, which drains better, made up 11.5 percent. Rated for dwellings without basements, about 75 percent of the points came back "very limited".
Plain English: a lot in Florida Shores can have different ground than one a few blocks over, and the water table rides high in the wet season. The real work happens in the footing trench and the base. That's where footing and foundation contractors in Edgewater earn their pay. The Florida Building Code sets exterior footings at least 12 inches below finished grade. It wants fill under a slab free of vegetation and compacted, and a 6-mil vapor retarder under house floor slabs. A new house also needs termite protection, with a certificate sent to the building department. Muck in the trench comes out, and clean fill goes in before any concrete does. You'll hear about it from us before that happens.
