Open WaterDockOnly

This dock fronts open water — a bay, harbor or marina basin rather than a canal.

There is no across-the-canal bank here, so no canal width applies and boat length is not limited by room to turn around. Check depth, beam and slip dimensions with the listing agent.

Description

Outstanding Waterfront Redevelopment or Restoration Opportunity! Rare point lot in Causeway Isles with 148 feet of direct water frontage and wide-open Boca Ciega Bay views. Enjoy a southern rear exposure offering both sunrise and sunset vistas. Located at the end of a quiet cul-de-sac, this property features deep water with no fixed bridges and quick access to the Gulf of America. The existing 4-bed, 4-bath, 2,522-sq-ft home was flooded and remediated after Hurricane Helene and qualifies for restoration under FEMA’s 50% rule with an updated appraisal. Ideal for a builder, developer, or buyer ready to renovate or rebuild a custom waterfront residence. Minutes to Treasure Island beaches and vibrant downtown St. Petersburg. A premier location and rare opportunity—don’t miss it!

Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map. Verify navigability with a local captain or surveyor before relying on it.
