Top 10 Design Considerations for Building on Old River, Ono Island

Building Along the Edge of the Gulf
When I walk a vacant lot along Old River — https://www.searchthegulf.com/homes-and-waterfront-properties-on-old-river-ono-island/, I see more than land — I see how the light falls across it, how the tide shifts, and how a home could rise with balance and purpose. Building here, along the southern edge of Ono Island — https://www.searchthegulf.com/ono-island/, is both a privilege and a craft.
Every decision — from how high the slab sits to how far the dock extends — carries both aesthetic and regulatory weight. Below, I’ve shared ten design considerations that I discuss with clients and builders before any form board is set or seawall is poured.
1. Orientation to Sun, Wind, and Water
On Old River, orientation dictates comfort. The southern exposure brings prevailing summer breezes and soft winter warmth, while light angles shift with the seasons.
When I consult on lot layout, I always position main living areas and porches toward the southeast to capture morning light and cross ventilation. Western-facing homes benefit from deep porches or Bahama shutters to diffuse afternoon heat while preserving sunset views.
2. Elevation and Flood Compliance
The Base Flood Elevation (BFE) for most Old River lots averages between 10–13 feet above sea level, though the Finished Floor Elevation (FFE) typically must be at least 1 foot above BFE to comply with FEMA and Baldwin County requirements.
If the grade is two inches above the road and the lot is flat, a monolithic slab can be the most efficient foundation choice. For lower or uneven sites, a stem wall foundation is ideal — it allows fill placement and perimeter height control without excessive sand import.
I always encourage buyers to request a topographical survey and elevation certificate before design work begins. These small investments save major expense during the Fortified Gold inspection phase.
3. Structural Fortification: Gold Standard
Ono Island’s Architectural Control Committee (ACC) mandates adherence to Fortified Gold standards, a coastal construction certification that reinforces roof-to-foundation connections and wind protection.
Key elements include:
-
Continuous load path from roof trusses to foundation.
-
Secondary water barrier under roofing material.
-
Impact-rated windows and doors with DP (Design Pressure) ratings suitable for 140 mph+ wind zones.
-
Corrosion-resistant fasteners and hurricane straps at every structural joint.
This certification not only protects the home but also significantly reduces insurance premiums — often by 20–30% annually.
4. Seawalls and Shoreline Protection
Before designing a dock or boathouse, assess the existing seawall.
Old River lots feature a mix of vinyl, concrete, and timber seawalls. Concrete offers longevity; vinyl provides flexibility against wave energy.
If no seawall exists, one will likely be required before construction.
Baldwin County permits often require engineering drawings with:
-
Elevation cross-section of shoreline,
-
Toe protection (riprap or geotextile mat), and
-
A setback that maintains stability above the mean high-water line.
For erosion control, native vegetation like Spartina grass and needle rush should remain intact where possible.
5. Dock, Lift, and Boathouse Placement
Under current Ono Island ACC guidelines, boathouses and docks may extend a maximum of 30 feet into the navigation channel, with 15-foot side setbacks from neighboring property lines.
For most Old River lots, the main channel depth ranges 7–12 feet, tapering to 5–8 feet near shore — ideal for center consoles, dual consoles, and sportfishing boats up to 45–50 feet.
I always verify water depth and piling spacing before final lift selection.
Typical lift ratings:
-
10,000 lbs for bay boats and pontoons
-
20,000 lbs for larger center consoles
-
30,000 lbs for sportfishers like the Viking 48 Convertible
Lighting, dock power, and plumbing should be engineered together to ensure compliance with both ACC electrical code and marine safety standards.
6. Setbacks and Lot Coverage
Per the Ono Island ACC, standard residential setbacks are:
-
Front: 25 feet from the road right-of-way
-
Sides: 10 feet minimum, 20 feet preferred between structures
-
Rear (waterfront): 30 feet minimum from the top of bank or seawall
Lot coverage is limited to 35% of total parcel area, including porches and accessory structures. This ensures consistent spacing between homes and protects the island’s open, coastal aesthetic.
7. Soil, Fill, and Drainage
Soil on the south side of Ono Island consists mainly of compactable sand — ideal for foundation support when properly engineered.
However, fill is almost always required to raise the FFE above BFE.
Imported sand typically costs $1,000–$1,500 per truckload, including delivery across the island bridge.
For drainage, swales should direct runoff toward the street or existing easements, not the river. Grading and sodding plans are reviewed by the ACC before approval.
8. Mechanical Placement and Noise Control
AC condensers, pool equipment, and standby generators must be positioned behind the front building line and screened from neighboring views with fencing or vegetation.
Generators larger than 20kW may require sound attenuation enclosures to meet Baldwin County’s 60 dBA residential limit.
Mechanical layouts are reviewed by both the ACC and the Ono Island POA prior to permit issuance.
9. Lighting, Elevation, and View Corridors
Old River’s charm lies in its darkness at night — the quiet shimmer of dock lights on the water. For new builds, I recommend downcast exterior fixtures and 3000K warm LED tones to protect wildlife and preserve the natural glow of the river.
Homes elevated above 12 feet should align roof ridges and second-story decks to avoid obstructing neighboring views. The ACC reviews sight-line elevations during design approval to maintain the visual rhythm of the riverfront.
10. Permitting, Surveys, and Partnerships
Building on Ono Island requires coordination between multiple entities:
-
Ono Island ACC for design and aesthetic compliance
-
Baldwin County Building Department for structural and flood compliance
-
FEMA for floodplain certification
-
A registered surveyor and civil engineer for grading and elevation
To streamline this process, I work closely with a network of trusted builders, architects, and engineers who specialize in coastal construction. They know Ono Island’s nuances — from elevation certification to final Fortified Gold inspection — and can navigate each step with efficiency and precision.
Final Thoughts
Designing a home along Old River is about far more than blueprints. It’s about understanding the relationship between structure and shoreline — how sunlight warms a porch, how the tide reflects under a dock, and how a home can stand secure for generations.
As a homeowner and advisor on Ono Island, I find deep joy in helping buyers and builders create something lasting — homes that honor the island’s natural beauty while meeting the standards that protect it.
If you’re considering building along Old River, I’d love to share my knowledge — from lot selection and dock placement to trusted builder introductions and ACC-ready design guidance.
