Summary
Clifton Code § 461-50 requires every retaining wall to resist the pressure of the material it holds back, including dead and live load surcharges, and to stand against overturning, sliding, foundation pressure and water uplift. A building permit with a certified plot plan is required before construction.
A. Retaining walls shall be designed to resist the pressure of the retained material, including both dead and live load surcharges to which they may be subjected, and to ensure stability against overturning, sliding, excessive foundation pressure and water uplift. B. When such walls are designed by a licensed architect or licensed engineer, these requirements may be modified subject to the approval of the Building Inspector and Engineering Department. C. A building permit is required showing certified plot plan, exact location of walls, elevation and plan of proposed walls. D. Whenever necessary to ensure safety to the public using a public street or highway, a retaining wall is required.

Full Breakdown
§ 461-50D adds a public-safety trigger: whenever a retaining wall is necessary to ensure safety to the public using a public street or highway, the wall becomes mandatory rather than optional, which comes up on sites where grading changes would otherwise leave an unsupported slope next to a sidewalk or roadway. The section sits in Article VIII alongside § 461-49, which treats any wall over two feet tall, other than a retaining or building wall, that does not meet the minimum building setback as a conditional use needing Planning Board approval, so a decorative wall over two feet and a load-bearing retaining wall are regulated on two separate tracks.
Violations & Fines
A retaining wall built without the § 461-50C permit, or one that does not meet the design standards in § 461-50A, is a Chapter 461 violation under § 461-71: fines run from $100 to $1,250, with up to 90 days of jail or community service possible and each day the unpermitted wall stands treated as a separate offense. The Building Inspector or Engineering Department can also require the wall be redesigned or removed for safety.
