The right-of-way permit, the SmartGov portal and the 24-hour inspection call
The Town runs its own permit desk, and homeowner driveway and street-edge work goes through a separate Permit for Construction on Town Right-of-Way. That form covers pavement cuts, driveways, storm drainage, tree removal in the right-of-way and sidewalks. You stake or paint the location and attach photos before you submit, and the permit is void if work doesn't begin within 30 days of approval. The form also tells you to call NC 811.
The Town prefers building permit applications through its SmartGov portal, and the residential packet lists a site plan showing setbacks. The Town Engineer reviews new or changed driveway entrances under the UDO. Book inspections by phone at least 24 hours ahead, because the Town doesn't schedule by voicemail. A wall at the street edge, or a drain pipe that has to outlet into the right-of-way, can bring this into play, so read the right-of-way form before we set stakes.
That street-side permit is separate from the building permit. The packet says approval of the driveway, erosion control and water and sewer service, or septic approval, has to be in hand before the building permit issues. Paperwork order matters as much as the pour date.
Built-upon area: what a terrace above the face does to your watershed math
The Town's UDO has a Watershed Protection Overlay with built-upon area limits. In the Rest of Watershed (WS-III) class, new development is held to 2 dwelling units per acre or 24 percent built-upon area, and the strictest class allows one dwelling unit per acre or 12 percent. The UDO defines built-upon area as impervious and partially impervious surface.
If your concrete retaining wall will carry a terrace, watch the flat patio, driveway or walk that lands on top of the fill. The UDO's built-upon definition takes in hard surfaces like those. If you're building a terrace to gain usable yard, ask the Town which watershed class your lot is in and how the limit applies to your lot, then size the terrace to fit. The Rest of Watershed class also has a 5/70 option that allows up to 70 percent built-upon area, but it covers non-residential and high-density attached development in limited cases, so don't count on it for a house lot. We'll price the structure and the slab as separate lines so you can drop one without redoing the other. Our patio page covers the surface that goes on top.
We price by the square foot of face, $25 to $45 per sq ft, poured or block up to about 4 feet. Length times height gives you the face.
| Job | Size | Per sq ft of face | What it comes to |
|---|---|---|---|
| Entry-walk side run | 14x3 ft (42 sq ft) | $25 to $45 | $1,050 to $1,890 |
| Terrace behind a house | 36x3 ft (108 sq ft) | $25 to $45 | $2,700 to $4,860 |
| Street-side cut at a driveway | 28x4 ft (112 sq ft) | $25 to $45 | $2,800 to $5,040 |
| Long yard terrace | 75x3 ft (225 sq ft) | $25 to $45 | $5,625 to $10,125 |
| Over about 4 ft | Engineered | Per design | Priced after the drawings |
Length times height times the range gives the base. Footing depth, drain stone, tree roots and truck access move the number. We give a free written estimate after we see the site.
