When a repair brings the whole wall up

Repairing half or more of the wall’s length, spending half the cost of a new wall, or changing the elevation along half the length counts as substantial. Then the full property length has to meet the minimum.

Miami River walls

River applications need a plan showing how the wall will be raised later, with load calculations, so it can keep pace with sea level through 2070.

Why it matters

What the City of Miami building permit needs

A signed and sealed survey less than a year old in NAVD88, a plot plan and construction details, bay-bottom title from the state, and preliminary county DERM approval (Secs. 29-84 and 29-85). Soil borings may be required.
