Ono Island Unit 12:
Shoalwater Drive & Bayou St. John

My detailed guide to this intimate row of 19 waterfront homesites, including the shoreline, lagoon, road geometry, turnarounds, setbacks, easements, lot measurements, and the practical questions I help buyers answer.

I know Unit 12 as one of Ono Island’s most cohesive waterfront neighborhoods: a graceful sweep of Bayou St. John homesites arranged along Shoalwater Drive. It feels more intimate than many of the island’s larger units because there are only 19 lots, one primary street, one continuous body of water, and a road pattern that slows naturally through several turnarounds.

Unit 12 Plat Map

What makes this area memorable is the relationship between road and shoreline. Every homesite runs from Shoalwater Drive toward Bayou St. John, while the curving water’s edge gives each parcel its own proportions. At the western end, a lagoon softens the shoreline and creates an especially distinctive setting. Toward the east, the road and shoreline narrow together before the street ends in a final turnaround.

When I help a buyer consider a Unit 12 property, I look beyond the street address. I compare the lot’s road frontage, side-line depth, shoreline width, setback area, easements, elevation, trees, existing improvements, and boating goals. That is how I begin to understand what a particular Shoalwater Drive property can truly offer.

“Unit 12 is a quiet ribbon of Bayou St. John waterfront, where 19 long homesites follow Shoalwater Drive from Ono Boulevard to the eastern turnaround.”

Unit 12 at a Glance

Where Is Unit 12?

Unit 12 lies along the northern shoreline of Ono Island in Baldwin County, Alabama. Bayou St. John forms the waterfront side of the neighborhood, and Shoalwater Drive serves the landward side of all 19 homesites.

The western entrance meets Ono Boulevard. From there, Shoalwater Drive bends northeastward with the natural shape of the island. The neighborhood extends in a long, slender line between the road and the bayou, ending in a turnaround near Lots 18 and 19.

This is protected bayou frontage rather than an Old River or Gulf-facing setting. The orientation creates a very different atmosphere from the island’s south shore, with a shoreline that meanders around small points, coves, and the lagoon at the western end.

Google Maps is provided for geographic orientation only. Legal boundaries, easements, setbacks, shoreline ownership, and the buildable area of any property require parcel-specific confirmation.

How the 19 Lots Are Arranged

Unit 12 includes 19 numbered homesites, and the overall composition is unusually consistent: the road is on one side and Bayou St. John is on the other. Even so, the lots are not interchangeable. The changing shoreline, the lagoon, the street curves, and the turnarounds create meaningful differences from one property to the next.

Shoalwater Drive and the Turnarounds

Shoalwater Drive occupies a 60-foot right-of-way. It enters Unit 12 from Ono Boulevard, follows the curve of the bayou, and continues to the eastern end of the neighborhood.

The road geometry includes multiple vehicular turnarounds. I count three distinct turnaround areas: an early pocket near the western homesites, a larger central bulb, and the final turnaround at the eastern end. These are practical access features, but they also affect the frontage and shape of the adjoining lots.

A lot beside a turnaround can have a generous curved frontage while still narrowing or widening differently behind it. For those properties, I always read the front arc, side lines, setback area, driveway approach, and utility locations together.

Measurements and Lot Geometry

Unit 12 contains approximately 1,603 feet of Bayou St. John shoreline. Individual waterfront widths vary because the shoreline is natural and meandering rather than a straight rear boundary. Many of the shoreline segments fall generally in the 60-to-85-foot range, with narrower and wider conditions where the water’s edge bends.

The homesites are predominantly long and narrow. Representative side depths run from the high 200s into the mid-300s in feet, and the deeper western measurements approach roughly 360 feet. Those depths extend toward the shoreline, so a simple rectangular calculation does not capture the true area or usable building envelope.

These figures are useful for understanding the neighborhood, but I use a current boundary and topographic survey for parcel-specific design or construction decisions.

Setbacks and the Building Envelope

Lots 1 through 15 have a revised front building-setback line dating to March 1986. The line follows the character of the land rather than creating one simple, uniform rectangle across every property. It bends through the western lagoon area and continues across the long central row of homesites.

I do not apply one universal setback distance to all 19 lots. Lots 16 through 19 have different geometry near the eastern curve, and every property must also be considered under current architectural review, flood-elevation requirements, utilities, drainage, septic or sewer conditions, shoreline regulations, and permitting standards.

Easements, Shared Rights, and Common Areas

Unit 12 includes easement rights for access, utilities, drainage, maintenance, repair, and related neighborhood purposes. One especially important corridor near Lot 5 accommodates a release pipe extending to mean sea level. I treat that as a property-specific design consideration whenever I am evaluating Lot 5 or an adjoining homesite.

The 60-foot Shoalwater Drive corridor and the vehicular turnarounds are shared-access features within the private subdivision framework. They should not be confused with extra lot area, and their location matters when planning a driveway, landscaping, fencing, drainage work, or construction staging.

There is no separately numbered park, clubhouse parcel, or recreational common element within Unit 12. The shared structure here is primarily the road, turnarounds, and easement network. Ownership and maintenance responsibilities should be confirmed through the current deed, title commitment, covenants, POA documents, and survey for the individual property.

The Lagoon and Bayou St. John Shoreline

The western lagoon is one of Unit 12’s defining features. It creates a sheltered indentation at the beginning of the neighborhood and gives the earliest lots a more complex relationship to the water than the straighter central homesites.

Across the remainder of Unit 12, Bayou St. John forms a continuous but naturally irregular shoreline. The lot lines were measured to the shoreline in June 1984, and the coastal edge has always required a more thoughtful reading than a fixed inland boundary.

For today’s buyer, I separate land-boundary questions from boating questions. A survey can help establish the property geometry; it does not guarantee present water depth, dock approval, vessel access, dredging rights, or the condition of an existing bulkhead, pier, lift, or boathouse.

Flood, Elevation, and Waterfront Due Diligence

Unit 12 has always been waterfront land within a recognized flood-hazard area. Its historical federal classification was Zone A-6 under the flood mapping identified in the mid-1970s. That old designation is part of the neighborhood’s history, not a current insurance determination.

For a present purchase or building plan, I verify the current FEMA flood zone, base flood elevation, finished-floor requirements, elevation certificate, drainage patterns, insurance options, and any property-specific engineering needs. I also look carefully at existing fill, seawalls or bulkheads, shoreline stabilization, trees, and how water moves across the lot during heavy rain and high-water events.

Why Unit 12 Is So Distinctive

I appreciate Unit 12 for its clarity and quietness. It is not a sprawling network of streets and interior blocks. It is one intimate waterfront neighborhood, following the northern edge of Ono Island with Bayou St. John always nearby.

Within that simple arrangement, every lot still has its own story. The lagoon, shoreline curves, turnarounds, easements, setbacks, elevations, and improvements create meaningful differences—and those are the details I help my clients understand.
