King tides, seawalls and storm water behind the house
Waterfront streets across Fort Lauderdale can see high tides push water onto low yards even on clear days, mostly in the fall. When rain arrives at the same time, water has nowhere to go. Many Rio Vista yards sit only a little above the water line, and soil near a seawall can drain slowly or wash away.
Seawalls themselves are regulated and are built by marine contractors, so we treat them as a boundary: our work starts at the wall and goes back toward the house. The key question for each yard is where rainwater will go when the canal is high, and how to keep soil from migrating through gaps at the wall.
