Free. No account, no email.
Key takeaways
- A small site ends coverage by removing the site notice, then sending a copy to the storm sewer operator within 30 days.
- The notice cannot come down until final stabilization is reached.
- Coverage ends when the notice is removed.
- Keep your records for 3 years from the day coverage ends.
A small site is 1 to under 5 acres. It files no NOI, so it files no Notice of Termination (NOT).
Some search answers say to file a NOT once the site reaches 70% cover. For a small site that is wrong. Only sites that filed an NOI file a NOT.
Steps
- Reach final stabilization: all soil disturbance done, and unpaved areas covered by even perennial vegetation at 70% of native cover or an equal permanent measure.
- Take down the site notice. It may not come down earlier.
- Fill in the removal part of the notice.
- Within 30 days of final stabilization, a transfer of control or another permit, send the completed notice to the storm sewer operator that got your first copy.
- Keep the SWP3, reports and notice for 3 years from the date coverage ends.
What counts as final stabilization?
All soil disturbance is finished. Unpaved areas have uniform perennial vegetation at a density of at least 70% of the native background cover, or an equal permanent measure such as riprap or gabions.
Read the full rule in final stabilization at 70%.
Is a homebuilder different?
On residential lots the homebuilder either finishes stabilization or sets temporary stabilization before the home transfers. The builder also tells the buyer why final stabilization is needed.
Which sites file a NOT?
| Site | How coverage ends |
|---|---|
| Small (1 to under 5 acres) | Remove the notice, complete its removal part, send a copy to the storm sewer operator within 30 days |
| Large secondary operator | Same as small |
| Large primary operator (filed an NOI) | File a NOT online within 30 days after final stabilization, a transfer, or other permit; copy to the storm sewer operator |
FAQ
When may a small construction site notice be removed?
Only after final stabilization. Then send the completed notice to the storm sewer operator within 30 days.
Do I file a Notice of Termination on a small site?
No. A small site has no NOI, so there is nothing to terminate.
What if the home sells before the grass grows?
The builder sets temporary stabilization before the transfer and tells the buyer why final stabilization is needed.
What does the city want at closeout?
That depends on the city. Corpus Christi asks for a copy of the removed small notice. See your city guide.
