01 / Dune Crossovers
AnswerDune crossover design, permitting, and construction for barrier island properties. FDEP CCCL coordination. Built to county spec on first submission.
The path from house to beach should feel permanent. We build it that way.

FDEP-permitted
Every project runs the full FDEP, USACE, and Indian River County permit pack — filed, tracked, and closed by us.
Engineered to ASCE 7
Stamped structural design against the lagoon's tide, surge, and salt — not a generic catalog spec.
One point of contact
One licensed Florida marine contractor (RG291103858) and one accountable crew — a single point of contact from design to final inspection.

01 / What you get
Dune Crossovers on the Indian River Lagoon.
· 01 — The challenge
A dune crossover built to county spec, the first time.
A compliant, properly built dune crossover meets county specification, requires no county-ordered removal, and lasts 15–25 years depending on material selection. We design and build to that standard on the first submission — the right stair riser heights, handrail systems, and clearance above the dune crest for sand passage, engineered in from the start.
· 02 — Our approach
How we design and build dune crossovers.
Crossover design begins with the property survey. Keith locates the Coastal Construction Control Line (CCCL) — the regulatory boundary that governs everything seaward of it — and confirms the crossover route and county-required clearance specifications. Material selection is determined by community aesthetic standards, maintenance preference, and budget.
· 03 — The lagoon
The Indian River Lagoon barrier islands — what they change about crossover work.
Barrier island properties — Orchid Island, John's Island beachfront — sit seaward of the Coastal Construction Control Line. The CCCL is an invisible regulatory boundary on every property. Any structure seaward of it is subject to stricter setback and design review under FDEP Coastal Construction rules.

What we specify, and why.
Composite decking is specified for most new crossover installations for its long, low-maintenance service life. Composite systems on aluminum or hot-dipped galvanized steel framing are specified where the community aesthetic requires a natural finish with composite performance. Handrail systems are engineered to IRC compliance standards — load, height, and balusting interval are non-negotiable county requirements, not design preferences.
04 / Investment
Dune crossover investment is driven by length, material selection, ADA compliance requirements, and handrail specification. Standard pressure-treated crossovers are the entry point; ADA-accessible composite designs with a full ramp grade sit at the upper end. We provide itemized scopes, not lump sums.
05 / Warranty
We don't hand you a warranty document full of fine print. If something we build isn't right, you call us and we come back and make it right. Manufacturer warranties on installed products — hardware, decking, and mechanical systems — pass through to you.
