Ridge sand or river bottom: what sits under your lot
Check the federal soil map at 60 spots across town and Roanoke and Warne soils, occasionally flooded, come up at twelve. Lakeland sand came up at seven, Lakeland-Urban land at five, Cape Fear loam at five, Altavista fine sandy loam, rarely flooded, at five, Johnston loam at four, and Wagram and Candor at three each. Roanoke is poorly drained, Cape Fear and Johnston are very poorly drained, Altavista is moderately well drained and Lakeland is excessively drained dry sand.
Several of the most common units are rated very limited for dwellings, so subgrade prep and drainage count for more here than in Hoke County. For a patterned slab it comes down to a simple split. On a ridge, the ground drains and the work is compacting loose sand and keeping the edges from washing. On bottomland, the base gets deeper stone and a firmer perimeter, since a settled corner stands out against a pattern. The soil survey is free to search by address.
Mapped zones and the 0.2 percent line
On FEMA's flood map, 50 spots spread across town break down as 34 in minimal-hazard Zone X, 13 in the shaded Zone X for a 0.2 percent annual chance of flooding and three in Zone AE, the mapped 100-year floodplain. That's about a quarter of them in the 0.2 percent zone. Treat it as a reason to look, not a ruling on your parcel.
Enter your address in the NC flood risk lookup. If you land in an AE zone, ask Cumberland County Planning & Inspections about floodplain steps before any fill goes in. Even outside the mapped zones, a low yard near Roanoke or Cape Fear ground can hold water after a hard rain, so tell us where it stands. We'll slope the surface, raise the edges where it makes sense and keep the pattern grading toward the lawn.
Pattern work is $12 to $20 per sq ft with color and sealer. Bottomland base work is quoted as its own line, so these are surface prices.
| Project | Size | Per sq ft | What it comes to |
|---|---|---|---|
| Walk to the door | 4x25 (100 sq ft) | $12 to $20 | $1,200 to $2,000 |
| Small seating patio | 12x14 (168 sq ft) | $12 to $20 | $2,016 to $3,360 |
| Family patio | 16x18 (288 sq ft) | $12 to $20 | $3,456 to $5,760 |
| Large patio with fire pit area | 400 sq ft | $12 to $20 | $4,800 to $8,000 |
A mapped floodplain lot, a deeper stone base on bottomland or a winter pour changes the lines beneath the surface price. We give a free written estimate after we see the site.
