Excavation for San Marco property owners
Excavation in San Marco starts with the property, not with a catalog. Our work spans San Marco, from San Marco Square through to the Southbank Riverwalk. In practice that means 1920s brick and stucco homes, riverfront property and small commercial buildings.
Before anything gets designed we look at what we're building on. Low-lying ground behind the river bulkhead where tidal flooding on Hendricks and the surrounding streets is a known, recurring condition, and the river is close and high — finished-floor elevation and backflow protection are live design issues, not paperwork.
Why excavation works differently in San Marco
Excavation in San Marco is an archaeology problem as much as an earthmoving one. Low-lying ground behind the river bulkhead where tidal flooding on Hendricks and the surrounding streets is a known, recurring condition. That means what the bucket finds — abandoned utilities on no map, old foundations, fill of unknown origin and quality — determines the schedule more than the volume does. Access compounds it: on infill lots the machine that fits through the side yard is often several sizes smaller than the machine the job wants. City floodplain rules that trigger substantial-improvement review once a renovation passes a value threshold.
The second local factor: compact 1920s masonry houses on small lots, where additions have to go up or back rather than sideways. So what fits San Marco is not automatically what fits the next community over.
Permits for that go through City of Jacksonville Building Inspection Division. We confirm exactly what applies to your parcel before design, rather than discovering it at review.
That's the whole reason we walk San Marco properties before quoting: the conditions above change the scope, and a number that ignores them isn't a number.

What actually drives the cost
We won't quote a number sight unseen. These are the factors that move it, so you can see where your project is likely to land before we ever walk the property.
- Cut and fill balance
- If material coming out can be used on site, you pay to move it once. If it has to be hauled off and clean fill hauled back in, you pay twice plus trucking. Balancing on site is the biggest single saving available.
- Water table depth
- Excavating below the water table means dewatering — pumps, time, and sometimes a permit. It is the difference between a straightforward dig and a managed one, and it is set by your site, not by us.
Serving San Marco.
We excavate on San Marco lots — foundation and footing work on infill sites, utility trenching around established services, and pool and addition excavation on properties where the equipment has to thread between houses. 1920s brick and stucco homes, riverfront property and small commercial buildings surround the work.
San Marco is one stop in a Duval County circuit that also takes in Jacksonville, Riverside, Avondale and Ortega.

What do you usually find under an older lot in San Marco?
Old foundations, buried debris, and utilities that aren't on any map. On San Marco infill parcels that's the main cost risk in excavation, which is why we call locates, look at the property's history, and price honestly rather than quoting a clean lot and discovering otherwise.
How much does excavation cost in San Marco?
Not without seeing the property, and any contractor who does is guessing. In San Marco the biggest single variable is usually the site itself — low-lying ground behind the river bulkhead where tidal flooding on Hendricks and the surrounding streets is a known, recurring condition — which changes the scope before anything else does. We'll walk it and give you a real number.
Does excavation in San Marco need a permit?
Yes. Approvals run through City of Jacksonville Building Inspection Division. City floodplain rules that trigger substantial-improvement review once a renovation passes a value threshold. We manage the applications and inspections; you should never be chasing a reviewer.
How quickly can excavation get underway in San Marco?
We'll come look at a San Marco property within days. What sets the build start is the permit, and city floodplain rules that trigger substantial-improvement review once a renovation passes a value threshold, which affects the timeline. We plan around it rather than hope.
Do you serve San Marco and the surrounding area?
Yes. San Marco is inside our regular service area from Keystone Heights, and we work throughout Duval County — including Jacksonville, Riverside and Avondale. Call (352) 478-6112 and we'll come look at the property.
Can you excavate close to an existing structure?
Yes, with the right equipment and shoring where the depth requires it. Excavating beside a foundation without accounting for the load it carries is how buildings crack, so this is a case where the slower method is the only method.
Do you do utility and septic trenching as well?
Yes — water, power, sewer and septic, at the required depth and separation, bedded and compacted so the ground doesn't settle over the line a year later.
