Webster FAQ
Do I need a permit for a 3-foot retaining wall in Worcester County?
Usually no under 780 CMR 1807 if no surcharge. But check local zoning and be aware that sloped backfill above the wall is considered surcharge, which may require engineering even for shorter walls.
Who designs large retaining walls in Worcester County?
A Massachusetts-licensed Professional Engineer must stamp plans for walls over 4 ft or with surcharge. Many segmental retaining wall (SRW) manufacturers provide pre-engineered charts that still require a site-specific PE review.
