# Erosion control and stormwater on NC home sites

NC permits and inspections

Check disturbed area, the larger development plan, current permit coverage, and control responsibilities before a grading crew opens ground.

Before your grading crew moves dirt, check which controls and approvals the home site needs. NC construction stormwater coverage applies to disturbance of one acre or more and to smaller sites within a qualifying larger common plan. Confirm the project boundary, erosion-control approval, and who holds the coverage before starting. Ask the administering agency about local requirements before treating an acreage threshold as permission to grade. [NC construction stormwater program][npdes]

## Check erosion, stormwater, and local grading approvals

Ask whether the work needs an erosion and sedimentation control plan, construction stormwater coverage, and local grading or stormwater approval. Those questions are connected, but a building permit alone does not answer all of them.

DEQ's erosion-control program administers the state's sediment-control framework through state and delegated local programs. The program addresses plan review, inspections, enforcement, and controls that prevent sediment pollution. [NC erosion and sediment control program][esc]

DEQ says erosion and sediment controls are required for covered land-disturbing activity regardless of its size. A plan-filing threshold is not an exemption from installing and maintaining controls. [Controls on smaller sites][esc-faq]

The state erosion-plan threshold and construction stormwater threshold use different wording. DEQ's FAQ describes a state plan requirement for disturbance of more than one acre. The construction stormwater program includes one acre or more and smaller qualifying common-plan sites. Local requirements can be more stringent. [State plan threshold][esc-faq] [Stormwater coverage threshold][npdes]

DEQ uses NCG01 for projects subject to its sediment program. It identifies NCG25 for projects subject to federal Clean Water Act construction coverage but outside that sediment-program category. Ask DEQ which route applies to the actual site. Check stormwater coverage even if no state erosion plan is required. [NCG01 and NCG25 applicability][npdes]

Check the disturbed area, not just the lot's size. Ask the responsible designer or permitting contact which work areas count, including associated access, stockpiles, and other disturbance. Get the accepted disturbance boundary. Do not estimate it from the house footprint.

Use [site readiness](/guides/site-readiness-checklist/) to give the grading crew the approvals and site limits before it arrives.

## A small lot can belong to a larger common plan

Check coverage for the larger development as well as the house pad. DEQ expressly covers disturbance below one acre when it forms part of a larger common plan meeting the program's size threshold. [Common-plan applicability][npdes]

For a subdivision lot, ask whether the developer's approvals cover the current owner and activity. Ask what happens when the builder purchases lots or responsibility passes between parties. A sign with the developer's permit number does not settle what the builder must do.

DEQ provides options for homebuilding lots and development phases. Its guidance explains that a separate certificate of coverage is not always required for every lot. It also emphasizes approved ownership and responsibility documentation. [Homebuilding coverage options][lots]

Check these items before clearing:

- Identify the owner or operator performing the disturbance.
- Identify the larger development and applicable approved plans.
- List the specific lots and phases included in the work.
- Obtain the certificate of coverage and responsibility documents.
- Ask which modifications or transfers are required for this purchase or phase.
- Confirm the responsible agency's answer before clearing.

The current DEQ program page describes transfer and new-coverage routes for purchased projects. Follow that current process for the actual transaction. Avoid reusing an older fact sheet's fee or portal instruction without checking it. [Purchased-project coverage][npdes]

## Who installs and maintains the controls

Compare the [excavation scope](/trades/excavation/) with the [landscaping scope](/trades/landscaping/) before assigning controls and final stabilization. The grading subcontract should name who installs and maintains controls, supports inspections, makes repairs, and stabilizes the site. The permit sets the permittee's legal responsibilities. A crew's promise to “take care of the silt fence” does not change them.

DEQ states that erosion controls must retain sediment on site and disturbed surfaces must become stable. The NC statute also establishes mandatory standards for land-disturbing activity. Read the approved plan and site-specific conditions before choosing a control. [DEQ control requirements][esc-faq] [G.S. 113A-57][nc-erosion]

Use this table to discuss scope when pricing sitework:

| Task | Scope question | Handoff record |
| --- | --- | --- |
| Initial controls | Who installs each approved measure before the related disturbance? | Plan location and installation acceptance |
| Access and deliveries | Who maintains the entrance and protects controls? | Agreed access route |
| Routine inspections | Who performs the permit's inspections and records findings? | Named person and current form |
| Repairs | Who supplies labor and materials after damage or sediment buildup? | Repair request and completion record |
| Stabilization | Who covers the disturbed areas at the required stage? | Accepted method and completion record |
| Final removal | Who authorizes removing temporary measures? | Agency release and agreed scope |

Include return visits in the scope. Ask what maintenance the bid excludes and how the crew responds to repair requests. Keep these contract discussions separate from the authority's acceptance of the control design.

## Give the grading crew an approved work boundary

Before equipment arrives, walk the site with the foreman and approved plan. Identify retained vegetation, protected areas, drainage paths, outlets, stockpile locations, and access. Ask the foreman to explain how the work stays inside the permitted disturbance.

Use the [site-readiness checklist](/guides/site-readiness-checklist/) to identify the control owner and the work boundary before releasing the grading crew.

DEQ describes erosion as soil movement and sedimentation as its deposition. Controls need to address both the exposed ground and the route by which runoff carries sediment away. Use the plan's measures rather than treating one perimeter product as the whole system. [Program explanation][esc]

Give later trades the same access instructions. Ask utility crews and delivery drivers to report damaged controls. Name who repairs controls before a trench or delivery route crosses them.

Use [home-building sequence](/guides/home-building-sequence/) to place return grading and stabilization visits in the schedule. Keep required controls in place while the construction sequence continues.

## Record inspections and assign repairs

The NCG01 permit sets self-inspection, recordkeeping, and reporting requirements. Its inspection table covers rainfall monitoring, erosion measures, outfalls, site boundaries, nearby waters, and stabilization. Use the current permit's conditions and applicable exceptions to set the schedule. [NCG010000 permit, Part III][ncg01]

Do not copy a rainfall trigger from a remembered older permit. Put the current table in the job file and assign someone to interpret it with the permittee. Keep any daily crew walk separate from the recorded inspections the permit requires.

Use inspection findings to create repair tasks. Identify the measure, location, observed condition, needed action, and completion evidence. A photo of a damaged control does not show that it has been repaired.

Keep the approved plan and changes available at the site. The permit requires current plan documentation and additional records. Ask the permittee where to find the records and how crews report completed repairs. [On-site recordkeeping requirements][ncg01]

If sediment leaves the site or a spill occurs, contact the permittee immediately. Use the permit's reporting requirements for the event. Check whether notification is due before waiting for the weekly handoff. [Reporting requirements][ncg01]

## Stabilize the site and terminate coverage

A finished house does not automatically close construction stormwater coverage. DEQ's process requires the applicable erosion-plan release and an electronic notice of termination. Its current page also explains that annual billing continues until coverage is formally terminated. [Coverage termination][npdes]

Confirm who obtains the final site inspection, keeps the release document, and submits the termination request. If the coverage includes other unfinished lots, check how closing one house affects the project. [Multi-lot closeout guidance][lots]

For work near Raleigh, confirm which city or county handles the site. [Wake County building permits](/guides/wake-county-building-permits/) can help identify the jurisdiction. Ask the responsible erosion and stormwater programs about their approvals.

DEQ's [local program directory][local-esc] identifies delegated erosion-control programs. Use the listed authority or the responsible DEQ regional office to confirm this site's approval route.

If demolition precedes grading, use [NC demolition and asbestos](/guides/nc-demolition-asbestos/) to separate building removal and hazardous-material work from the land-disturbance approvals.

Find related local checkpoints in [NC permits and inspections](/guides/topics/nc-permits-and-inspections/).
