Commercial and municipal shoreline stabilization after the 2017 and 2019 high water events. $20K minimum project size. Marinas, campgrounds, state parks, large estates. Permit coordination included.
The May 2017 Lake Ontario high water event crested at 248.95 feet IGLD. Two years later, May 2019 pushed it to 249.08 feet. Oswego County took the worst of it. Sodus Point lost beach, bulkheads, and in some cases entire lawns. Fair Haven campgrounds watched revetments slide into the lake. Sackets Harbor seawalls cracked. Some properties lost 15 to 40 feet of bank in a single season. Seven years later, many of those shorelines still aren't stabilized , because owners got quoted $200,000 and walked away, or they hired the wrong contractor and the work failed the next spring.
Backwell handles commercial and large-scale shoreline stabilization on Lake Ontario, Oneida Lake, and the Finger Lakes. We are a commercial excavation contractor based in Syracuse. We are not a camp repair service. If you're reading this page looking to armor 60 feet of cottage frontage for $8,000, stop reading , we tell you who to call instead at the bottom.
We take shoreline stabilization projects starting at $20,000 , usually a short run of engineered riprap on a commercial property or a simple armoring job at a marina. Most of our shoreline work lands between $80,000 and $300,000. Full reconstruction for a marina, campground, or municipal park can run $500,000+. A steel sheet pile wall along 400-foot commercial frontage with backfill, drainage, and permit management can exceed $1 million.

This isn't a calm inland pond. Lake Ontario is the eastern terminus of the Great Lakes. Prevailing westerly winds have a fetch of over 200 miles before they hit the New York shoreline. Wave energy on the Oswego and Jefferson County coast is multiples of what you'd see on a Finger Lake or Lake Erie's Pennsylvania shore. Storm waves in fall and early spring routinely exceed 8 to 12 feet offshore and break with tremendous force at the toe of any structure.
Add ice. From January through March, sheet ice forms along the shoreline, gets shoved by wind, and scours everything at the waterline. Ice can rip out undersized stone, bend vinyl sheet piling, and tear apart concrete that isn't properly reinforced. Freeze-thaw cycles work through any cracks in spring.
The 2017 and 2019 high water events added a fourth factor: prolonged static high water. When the lake sits 2 to 3 feet above regulated average for months, structures designed for a lower waterline get overtopped and undermined. Toe scour accelerates. Backfill washes out. Anything built assuming a normal IGLD elevation fails.
Any solution that doesn't account for all four , wave energy, ice, freeze-thaw, and high-water duration , will fail within 3-5 years. We see it constantly.
You cannot legally touch a Lake Ontario shoreline without permits:
Permit timelines run 4 to 12 months. If you haven't started the permit process, you're probably looking at next summer. We manage permit applications as part of turnkey projects.
Engineered stone armoring. Sized quarry stone (1-5 ton) over geotextile fabric with a keyed toe trench below anticipated scour depth. Our most common approach for reasonable backshore slopes. Handles Lake Ontario wave energy and ice when designed correctly. Fails when undersized or when toe isn't deep enough.
For vertical walls where backshore space is limited. Marinas, commercial docks, urban waterfronts. Z-profile hot-rolled steel or heavy-gauge vinyl, tieback anchors for walls over 8 feet exposed, capped with concrete or timber. 50+ years with proper cathodic protection.
Similar to riprap but with shaped or hand-placed stone. Higher cost, better aesthetics. Used on estate properties, state parks, historic sites.
Bioengineered approach: coir logs, live stakes, native plantings, stone toe. DEC-preferred when site has low enough wave energy. Most Lake Ontario shoreline is too exposed for pure living shoreline, but hybrid approaches (stone toe + vegetated upper bank) work well on sheltered embayments.
We get calls every week from small seasonal camp owners who want someone to "throw some rock down" for $5,000 or $8,000. We cannot help you, and here's why:
If you have a small camp and tight budget, call a local handyman excavation contractor or contact your county Soil and Water Conservation District , they sometimes have cost-share programs for residential shoreline.
8 to 18 months. Design: 1-3 months. Permitting: 4-12 months. Construction: 2-10 weeks. Anyone promising faster has existing permits or is cutting corners.
Yes for some methods. Frozen ground helps with access. Ice cover limits in-water work. DEC permit conditions often restrict construction windows. We plan major projects for September through December when possible.
Yes , we coordinate permits on turnkey projects and work with licensed coastal engineers for stamped designs that DEC and Army Corps require.
30-50 years with minimal maintenance when designed correctly. Sheet pile: 40-60 years. The difference between 5-year failure and 50-year structure is almost entirely design/installation quality , stone size, toe depth, geotextile, keyway.
For projects above $150,000, yes. We work the entire Lake Ontario shoreline from Niagara to Jefferson County, the St. Lawrence River, Oneida Lake, and the Finger Lakes.
If your project fits , commercial, municipal, institutional, or a large estate with serious budget , call (315) 400-2654 for a site visit. Bring photos, property map, existing engineering. We'll tell you honestly whether the project fits.
