Temporary vs. Permanent Erosion Control: What's the Difference?
Temporary erosion control buys time during active construction; permanent erosion control is what a site is built to live with after the project closes out — confusing the two leads to compliance gaps at closeout.

Temporary Erosion Control
Methods like temporary seeding, mulch, and erosion control blankets are designed to stabilize soil for the duration of active construction, typically on areas that will be regraded again later in the project or that don't yet have final landscaping plans in place.
Permanent Erosion Control
Sod, permanent seeding with established vegetation, riprap, and other long-term stabilization methods are intended to hold once an area reaches final grade and won't be disturbed again — this is what the NPDES CGP refers to as 'final stabilization.'
Why the Distinction Matters at Closeout
Filing a Notice of Termination generally requires final stabilization across the site, meaning areas left with only temporary measures in place can hold up permit closeout even after construction work itself has finished.
Making the Transition on a Phased Site
On multi-phase projects, areas reaching final grade should transition to permanent stabilization as they're completed rather than waiting for the whole site to finish — tracking this area-by-area avoids a backlog of temporary measures that all need converting at once near closeout.
Frequently Asked Questions
Can temporary erosion control satisfy final stabilization requirements?
Generally no — final stabilization for NOT filing purposes typically requires permanent measures like established vegetation, sod, or riprap, not temporary seeding or mulch alone.
When should a site switch from temporary to permanent stabilization?
As soon as an area reaches final grade and won't be disturbed again, rather than waiting for the entire project to finish — tracking this area-by-area keeps the transition manageable on phased sites.
