Ramrod Key seawall repair

Get to know your waterfront

Ramrod sits at mile marker 27 with three county canals: 310, 311 and 350. Canal 350 runs about 6,000 feet past Indies Drive and lanes named for Caribbean islands, from Anguila to St Vincent. Beneath the key, USGS maps a change in rock type on its south side.

What shapes a Ramrod Key seawall job

Canal 350: one system, 461 parcels

Canal 350 is the center of Ramrod’s waterfront. The county counts 461 parcels along roughly 6,000 feet of it, and its listed treatment reads "defunct aerators, 1982 culvert" in the county layer. County residential canal layer

Its streets include Indies Drive and lanes such as Antigua, Barbados, Cayman, Jamaica, Martinique and Tobago. County canal street list When this many lots share one canal, neighbors may share wall age and water access too. A joint assessment or bid is worth asking about; the neighbor group guide explains how.

Rock can change within one neighborhood

USGS places a geologic contact on the south part of Ramrod. There, the Key Largo reef rock of the Newfound Harbor Keys meets Miami Limestone, the cemented oolite that forms the Lower Keys. USGS Professional Paper 1751, Tile 5

Both formations wear a hard soilstone crust. USGS mapping is regional, so a boring or probe at your lot decides between driven sheet pile and a drilled or poured design. USGS regional geology

• Get a boring or probe at your wall line before you compare bids.
• Ask each bidder how the price changes if they hit rock or crust early.
• Expect the nearshore ledge, which USGS describes as submerged reef and oolite, to matter for riprap and dock pilings too.

USGS calls the Newfound Harbor Keys the westernmost emergent piece of the Key Largo reef. It also notes that the reef’s coral skeletons show in the walls of man-made canals. USGS regional geology If you can see coral texture in your canal wall, tell your engineer.

Where the sanctuary begins

The Florida Keys National Marine Sanctuary starts at the mean high-water mark, so a canal wall face sits right at its edge. Sanctuary boundary, 15 CFR 922 NOAA lists seawall repairs that could affect corals among the jobs needing sanctuary review. NOAA sanctuary permit page

With a reef and oolite ledge nearshore, ask your designer early if a seafloor (benthic) survey will be needed. It is easier to schedule one up front than to add it after the state and federal files are in.

Breezeswept roads in the 2025 group

The road study put Breezeswept Beach Estates, area 39 with 24,200 feet of road, in its 2025 adaptation group. Area 78, covering Silver Shores Estates and Ramrod Shores, joined it with 12,645 feet. County road study, Table 2

On the county’s critical list, 25 Breezeswept segments serve 291 residential units. Design any new cap with the future street grade in mind, and ask the county for current status first. County critical roads list

Storm water on Ramrod

• Georges, 1998: The Hurricane Center’s table lists 5 to 6 feet of surge for Ramrod Key. Hurricane Center Georges report, Table 2
• Irma, 2017: Ramrod lies inside the Cudjoe-to-Big Pine reach, where the Hurricane Center put inundation at 5 to 8 feet above ground level. Hurricane Center Irma report

Canals 310 and 311

Canal 310 serves Brown Drive, Lesrohde Drive and Mariposa Road, and canal 311 serves Coral Avenue. County canal street list On the 2021 ranking, 311 placed 38th for backfill only, and 310 placed 46th for a culvert, with a "Limited Data - Poor" note. County canal ranking list, 2021

The Torch Keys guide covers the island where USGS maps the same rock contact, and the Summerland Key guide covers the next key west. Every key is compared on the Lower Keys overview, and the permits page explains each agency’s role.

What could the work cost?

Rock is the big unknown on Ramrod. Ask every bidder to state what their price assumes about rock at the wall line, and get the boring done before you sign. On canal 350, ask whether neighbors on your reach want to share mobilization costs.

Calculator ranges come from a 2026 national cost guide and one Key West public bid. None is a quote; your written, itemized scope sets your price.

A Ramrod Key planning checklist

Work through these before you sign anything for a Ramrod wall.

1. Confirm canal 350, 310 or 311

   Look up your lane in the county street list. The Residential Canals map file shows the canal outline, so you can confirm which of the three you are on.

2. Order a boring at the wall line

   USGS maps reef rock and oolite meeting on south Ramrod. Only a lot-specific boring tells your engineer which one your wall stands in.

3. Call about road area 39 or 78

   Breezeswept is area 39; Silver Shores Estates and Ramrod Shores are area 78. Ask the county where each stands so your new cap and the future street grade work together.

4. Talk to the neighbors on your reach

   With 461 parcels on canal 350, nearby owners may want to share an assessment, a survey or a bid.
