Celina, TX SWPPP & Stormwater Requirements
Updated July 2026
Celina holds construction stormwater closer than almost anyone in North Texas, and it says so in its own ordinance. Celina stormwater requirements are city rules layered on top of the state permit — and here, the city's layer starts long before the state's does.
What does Celina require for SWPPP compliance?
Celina's threshold is the story here: the city starts regulating dirt work at a size the state permit never reaches, and its paperwork ladder climbs from there. Celina requires a valid earthwork permit from the city before commencing disturbance of 0.1 acre or more of land.
The earthwork permit starts early — and the plan requirement starts earlier
Even below the permit threshold, the erosion control obligation is already running. Celina's erosion control article requires a responsible party engaging in any land-disturbing or construction activity to prepare an erosion control plan and submit it to the city for approval — and it applies regardless of whether a city permit is otherwise required. Celina's permitting starts at a fraction of an acre — get the paperwork moving before the first pass of the dozer.
The paperwork ladder by project size
The state's own line sits at an acre. TXR150000 defines small construction activity to include clearing, grading, and excavating that disturb at least one acre and less than five acres. Celina's ordinance builds its submittal ladder on top of that. For land disturbances of 1.0 to 5.0 acres, Celina requires a construction site notice (CSN) from a completed stormwater pollution prevention plan (SWPPP). At 5.0 acres or greater, Celina requires a notice of intent (NOI) with proof of payment to TCEQ — and a notice of termination (NOT) to TCEQ once the project is complete and permanent erosion control is established. The proof-of-payment detail matters: the city checks that the state filing actually happened before the dirt moves, and closes the loop at the end.
The region's only Gold-certified stormwater program
Celina's posture is not just strict on paper. In the spring of 2021, Celina was awarded the first-ever Gold iSWM designation by the North Central Texas Council of Governments. Celina operates under a city Stormwater Management Plan covering August 2024 to August 2029. Read that as a working signal: reviewers here know the standard, apply it, and expect submittals that take it as seriously as they do.
Inspections: the baseline still runs underneath
TXR150000's standard schedule requires construction site inspections at least once every 14 calendar days and within 24 hours of the end of a storm event of 0.5 inches or greater. That record has to exist from the first disturbance to final stabilization. Terradyne provides routine SWPPP inspection reports with cloud-based client access. See SWPPP Inspections for how the program works, and Silt Fence Installation for the perimeter the reviewers will look at first.

Frequently Asked Questions
When does a Celina project need an earthwork permit?
Far earlier than most operators expect — the city's threshold is a tenth of an acre, an order of magnitude below where the state permit picks up. If you are disturbing ground in Celina, assume the city wants paperwork before you start and check the ordinance's exact triggers.
What stormwater paperwork does each project size owe in Celina?
The city ladder tracks project size: an erosion control plan applies to land-disturbing work generally, mid-size disturbances add a construction site notice from a completed plan, and the largest projects file the state notice with proof of payment — then close out with a termination notice once the ground is stable.
What does iSWM Gold mean for my project?
It means Celina's reviewers work to the regional stormwater standard's top certification — the first city to earn it. Practically: expect thorough plan review, expect the details to be enforced as written, and bring submittals that match that bar the first time.
Who handles the inspections once work starts?
The operator owns the inspection record through final stabilization. Most builders put it on a standing program — a qualified inspector walking the site on the required rhythm, with reports the whole team can see — rather than chasing it storm by storm.
