Zoning permit first, building permit second
Erwin splits its paperwork between two offices. The Town's Planning and Zoning office issues the zoning permit. Harnett County's inspection department handles building inspections for the Town under an interlocal agreement, and that agreement says no building permit can be issued for construction, repair or improvement to land or a structure inside town until the Town has issued a zoning permit or comparable approval. Get the order backward and your file sits. Take the approved zoning permit to the county with your plans.
The Town's zoning application wants a plot or site plan showing the lot shape, existing and proposed buildings, parking, access drives and yard dimensions. It also asks for the estimated project cost, whether the property takes access from a DOT road, and whether it sits in a floodplain, watershed or wetlands. Town staff fill in the zoning district, the setbacks and whether the Town wants a foundation inspection. Draw the paving on that plan before anyone prices it. You'll find the forms on the Town's planning and inspections page, and our permit guide shows how the pieces fit.
Flat ground, hydric soil and two rivers
The Town's 2023 Land Use Plan puts the water problem plainly. The Cape Fear River runs along the west side of town and the Black River drains the east side, with large floodplains and wetlands beside the rivers and creeks. The Plan calls drainage and stormwater an issue wherever the ground is relatively flat and hydric soils occur. A pad poured on flat, wet ground has nowhere to shed rain unless somebody builds it a path.
The soil map backs the Plan up. Norfolk loamy sand and Norfolk-Urban land cover 15 of 40 sample points, and Norfolk drains well. Wahee, a somewhat poorly drained soil, shows up three times, and Bibb, which floods frequently, three more. The FEMA map points split too: 29 of 40 landed in minimal-hazard Zone X, eight in the 0.2 percent annual chance area, and two in Zone AE, one of them a floodway. About one point in four sits outside the minimal-hazard zone. We set a pad slightly above the surrounding grade and pitch it to a low edge. Check your parcel in the NC flood risk lookup; the Town also posts a Floodplain Development Permit application.
A reinforced 5 to 6 inch slab runs $8 to $14 per sq ft. Each figure below is that range times the square footage, and the final price comes after a site visit.
| Job | Size | Per sq ft | What it comes to |
|---|---|---|---|
| Storefront walk | 5x40 (200 sq ft) | $8 to $14 | $1,600 to $2,800 |
| Rear service pad | 15x20 (300 sq ft) | $8 to $14 | $2,400 to $4,200 |
| Truck apron | 24x25 (600 sq ft) | $8 to $14 | $4,800 to $8,400 |
| Parking bay | 30x60 (1,800 sq ft) | $8 to $14 | $14,400 to $25,200 |
Extra stone on wet ground, grading to a drainage edge, tear-out of an old walk and the NCDOT wait can move an Erwin total. Every price is confirmed in a free written estimate after we see the site.
