Twin Lakes seawall repair planning
Coordinate a shoreline repair with the documented road, pump, swale, and inlet system rather than treating each elevation separately.

Get to know your waterfront
Twin Lakes provides an unusually concrete reason to inspect the entire route from house to canal. Its public project combines road elevation with a pump-and-treat drainage system, and county updates identify work on Shaw Drive, Crane Street, and Adams Drive. For a waterfront owner, the key question is how the finished lot will drain around those improvements while the seawall, cap, and retained soil do their separate jobs.
Fit the repair to the road and drainage system
Bring the most recent Twin Lakes project drawings to the first waterfront assessment. The county’s work includes both road elevation and mechanical drainage; its published road target is not a specification for your seawall. A contractor should explain the elevation reference used in the private proposal and how it connects to the actual finished grades. Twin Lakes road elevation and drainage project
Walk the property from the road toward the canal and identify every swale, inlet, driveway edge, and low spot. Keep a separate record of wall movement, open joints, and soil settlement. The resulting sketch helps a designer distinguish a drainage connection issue from a structural repair and prevents a new cap or paved surface from unintentionally blocking an existing route for water.
Access deserves its own check. The county’s January 2026 bulletin identified a particular Shaw Drive segment, while other updates name Crane Street and Adams Drive. Those notices establish where work was planned or taking place at those dates; they do not tell a truck driver what is open today. Twin Lakes road elevation and drainage project
Before accepting a proposal, ask who will verify the public improvements’ current condition, protect drainage equipment during staging, and restore any driveway or yard disturbed by the private work. Record those responsibilities in the scope.
What could the work cost?
Twin Lakes proposals should price access, driveway restoration, and protection of nearby drainage features explicitly. If the road project affects finished grades at your lot, obtain that information before comparing repair bids. Keep public infrastructure costs separate from the private wall estimate; the county’s project does not establish a homeowner price.

| Starting point | What to resolve | Prepare and look up |
|---|---|---|
Monroe County Building Department — Key Largo office | Confirm the parcel, complete marine scope and local review route. | Bring the survey, existing permits, proposed drawings and access plan. |
Environmental and federal review | Resolve in-water work, habitat, submerged lands and sanctuary requirements. | Use one complete scope to confirm the DEP, Corps and sanctuary authorizations that apply. |
Coordinate the lot with public drainage
Use these local records to prepare a property-specific discussion with your designer and the responsible authority.
Read the dated construction bulletins
Check the county Twin Lakes page for notices covering your street, then confirm the current situation before arranging deliveries.
Confirm the elevation reference
Ask the designer to distinguish the published roadway target from the project-specific cap and yard elevations in your own plans.
Document drainage before mobilization
Photograph adjacent inlets, swales, and access routes. Have the contractor state how these will be protected while wall work is underway.
Prepare your Twin Lakes project
Start with the address, visible changes and records you have. Separate observations from questions that need a site assessment.

Twin Lakes project questions
Is the Twin Lakes road elevation also the required seawall height?
No. The county’s published 13-inch NAVD88 figure describes its roadway project. A private seawall needs its own design, permit review, and elevation information for the waterfront lot.
Are the county’s Shaw Drive notices proof the road is closed now?
No. The cited bulletin is from January 2026. Use the project page to identify the work area, then ask the county or project team about present access before scheduling equipment.
