Lowell FAQ
What erosion controls do I need for a small project?
At minimum, silt fence down-gradient of disturbed soil, a stabilized gravel construction entrance, and covered or seeded stockpiles.
Do wetlands rules apply to my yard?
Yes if any portion of your yard is within 100 feet of a wetland, stream, or the Merrimack or Concord Rivers.

If your addition disturbs 5,000 sq ft or more of soil, or is on a slope over 15%, yes. Smaller projects may still need inlet protection on downhill catch basins.
What happens if my erosion controls fail?
DPW can issue stop-work orders, require immediate remediation, and fine up to $300 per day per violation. Sediment that enters storm drains triggers additional clean-up costs.
