Before: floating jet ski dock with marine growth along the waterline

North Miami's boats live on the east side of the city, in the gated canal neighborhoods of Keystone Point and Sans Souci, where the canals run out to Biscayne Bay. The Oleta River, the only natural river in Miami-Dade that has never been dredged or channelized, meets the bay right next door and pushes fresh water into it, so hulls here sit where river and bay water mix.

Fresh water meets the bay

The Oleta River drains into the north end of Biscayne Bay at Oleta River State Park, 1,033 acres of mangrove and bay beach just beside the city and the FIU Biscayne Bay Campus. The river and the Upper Oleta are idle-speed, no-wake zones, and the Biscayne Bay Aquatic Preserve begins at the river's headwaters. The Biscayne Canal, dug in 1924 to drain farmland around Arch Creek, also runs through the city to the bay, and its flood gate (S-28) is one of the county's most frequent manatee gathering spots.

Fresh water coming in from the river and the canal means North Miami hulls grow a mix of soft slime and hard barnacles, and the electrolysis around a dock varies from canal to canal. That is why we don't guess about zincs here: the diver records each anode's percentage every month and replaces it at 50%. North Biscayne Bay's seagrass beds hold the county's highest manatee densities, which is a good reason to keep a slow, quiet diver on the job rather than a haul-out.

Where we dive in North Miami

Keystone Point is a set of gated peninsulas in ZIP 33181 with canals to the bay, and it is our busiest stop in the city. Sans Souci Estates is a gated bayfront community with deep-water canals. Both are private-dock neighborhoods, so tell us the access details once; after that the diver works from the dock and leaves the report and photos behind. Boats headed for the ocean go north past the Broad Causeway (idle speed at the bridge) to Bakers Haulover Inlet, and Haulover Park's marina by the inlet is on our route as well. ZIP 33161 covers the rest of the waterfront.

Docks and seawalls on the canals

Canal docks in Keystone Point and Sans Souci sit in still water where oysters build up on pilings and floating-dock wheels undisturbed. We clean them without pickaxes or chisels, and every cleaning includes a multi-point inspection. We have not found a North Miami seawall ordinance, so a seawall inspection here is about the wall's condition and the lender-required documentation that almost every canal-front sale needs: $250 for a home, $350 for a multi-family property.

North Miami owners ask

My boat is in a Keystone Point canal. How often should I have it cleaned?

Every 30 days, or every two weeks if the canal turns out to be nutrient-rich or the hull has no bottom paint. Canal water in Keystone Point is still, so nothing knocks the growth off between trips; the monthly photos tell you which schedule your dock needs.

Does fresh water from the Oleta River affect my hull or zincs?

It affects the zincs more than the hull. The Oleta and the Biscayne Canal push fresh water into this end of the bay, and zinc wear depends on the electrolysis right around your boat, so anodes here last anywhere from 3 to 13 months. We record the percentage every month and replace them at 50%.

I live in Sans Souci and I'm selling my house. Do I need a seawall inspection?

Almost certainly: lenders require seawall documentation on nearly every waterfront home sale. The residential inspection is $250, the diver cleans the growth off before judging the wall, and the documentation covers its condition.

Can you find something I dropped off my dock?

Yes. We recover lost items from the bottom, and we offer 24/7 emergency service, so a phone or a set of keys that went off a Keystone Point dock doesn't have to wait until Monday.
