| Permit trigger | 1 or more acres disturbed (or part of a plan that will disturb 1 or more acres) needs an NPDES construction stormwater permit. | EPA, Stormwater Discharges from Construction Activities (NPDES)As of September 2026 |
| Inspection frequency | The federal CGP requires a site inspection within 24 hours of any storm producing 0.25 inches or more of rain. | EPA, Construction General Permit (CGP) Frequent QuestionsAs of September 2026 |
| Stabilization deadline | Disturbed areas where work stops for 14 or more days must be stabilized within 14 calendar days. | EPA, Construction General Permit (CGP) Frequent QuestionsAs of September 2026 |
Project guide
Erosion and sediment control keeps disturbed soil on the site and out of storm drains, ditches and neighboring property while construction is under way and until vegetation is established. Under the federal Clean Water Act, any project that disturbs one acre or more needs coverage under a construction stormwater permit and a written plan, commonly called a SWPPP, and many cities set lower thresholds. The physical work is simple and unglamorous: silt fence trenched in along the downhill perimeter, a stone construction entrance so trucks do not track mud onto the road, protection around every inlet, check dams in ditches, and erosion control blanket or hydroseed on slopes. What most owners underestimate is the maintenance: controls have to be inspected after every rain of a quarter inch or more and repaired, and inspectors write violations for torn fence and full silt traps, not for missing paperwork.
GradeLine lists 2,220 erosion control contractors.Compare their work and equipment, then confirm availability and service area before requesting a quote.
Listed businesses are based in Gadsden, , Darmstadt, Pittsburgh, Macedon, Flat Rock, though most crews travel well beyond their home city.
Silt fence typically costs $2 to $5 per linear foot installed, a stabilized stone construction entrance $1,500 to $4,000, and hydroseeding roughly $0.10 to $0.25 per square foot. A full erosion control package for a single-family lot commonly runs $1,500 to $5,000, while an acre of open ground on a commercial site can reach five figures once inspections and maintenance are included.
Ranges are national and approximate; regional labor rates, material prices and site conditions move them in both directions.

Send the stormwater plan or SWPPP if one exists, the grading plan, the schedule of when soil will be opened up, and where water leaves the site.
The main cost items are perimeter length, the acreage of exposed soil and the steepness of slopes on the site; the specific products the plan calls for, such as wire-backed silt fence or a particular blanket class; inspection frequency, how long the project stays open, and how many repairs are expected before final stabilization. A site visit helps the crew see which ones apply.
Disturbing one acre or more requires an NPDES construction stormwater permit from the state or EPA and a written SWPPP kept on site. Many counties require an erosion control permit and a pre-construction inspection for smaller projects, and fines for sediment leaving the site can run into the thousands per day.
