Riviera Bay is an established waterfront neighborhood in northeast St. Petersburg, Pinellas County, laid out on land along a network of navigable canals that connect to Riviera Bay and open Tampa Bay. The area traces to early dredging tied to the development of nearby Weedon Island in the 1920s, and the neighborhood sits across the water from the Weedon Island Preserve. The main ZIP is 33702, near the Gandy corridor and I-275. This guide covers the broader Riviera Bay area, including the Riviera Bay Second Addition plat.
Homes are predominantly single-family and largely mid-century, with much of the stock built from roughly the late 1940s through the 1970s and many homes since remodeled, along with newer elevated rebuilds appearing after the 2024 storms. Many are ranch-style or raised homes, some with oversized first-floor garages, and a large share sit on canals with private docks while others are interior, non-waterfront homes. The Riviera Bay Civic Association is an active voluntary organization, well known for the Christmas Eve boat parade and seasonal golf-cart parades, and there is generally no mandatory HOA and no CDD, though you should confirm per parcel.
The defining reality of Riviera Bay is flood and elevation. The neighborhood is low-lying, and Hurricanes Helene and Milton in the fall of 2024 brought storm surge and flooding to parts of the area. Residents have reported canals filled with sand and sediment from the surge, which led the city to fund a study of canal dredging in late 2025. Elevation, flood zone, prior flood and substantial-damage history, and insurance cost must be verified for the specific home.
A second item specific to Riviera Bay is canal depth and navigability. Several canals are described by residents as shallow and silted, and the city dredging study, funded in December 2025, is meant to define the sedimentation problem before any dredging, a process that could take years. For a buyer paying for canal access, current depth, draft, and dredging status matter, so confirm them for the specific home rather than assuming deep-water access.
