Riverstone at a glance
A single-PUD subdivision in southwest Lakeland between Ewell Road and Medulla Road, with Curtis Lake inside and about 1,200 homes on 2019 to 2021 plats.
Mostly Pomona fine sand, poorly to very poorly drained flatwoods ground. FEMA maps roughly a fifth of the area in Zone A, so check your own lot's flood zone.
Permit office: City of Lakeland Building Inspection Division · official page No historic district. City-owned streets, so apron work needs a Right-of-Way Use Permit; Zone A lots can't use the HB 803 exemption.
Riverstone by the record: 1,200 houses, four plats, one PUD
Riverstone is in southwest Lakeland, inside city limits, in Polk County. Ewell Road runs along one edge and Medulla Road cuts through it. Hatcher Road and Towne Park Boulevard sit just outside. Curtis Lake is inside the neighborhood, and Lakeland Linder International Airport is under two kilometers away.
The Polk County Property Appraiser's recorded subdivision layer shows Phase 1 recorded in October 2019 and Phases 5 and 6 in June 2021, and the City's zoning map labels the whole area PUD 5677. That comes to about 1,200 single-family homes and no townhomes, all on original builder slabs. On slabs this young, think additions: a back patio, a wider driveway or a side walk. The rest of the city we cover is on our Lakeland service area page.

Pomona fine sand under the lawns, and what poorly drained means for a slab
The USDA soil map for Riverstone is mostly Pomona fine sand. The official Pomona series description calls it very deep, poorly and very poorly drained, found on flats and flatwoods. The smaller units around it (Floridana, Smyrna, Myakka and Eaton) drain poorly too. You won't find well-drained ridge sand anywhere in this subdivision.
On a slab, that changes three things. First, the base: we strip topsoil and roots and compact clean sand in lifts. That borrows the Florida Building Code rule for fill under a house slab: free of vegetation and compacted for uniform support. Next, the grade: a new patio or widening has to shed water toward the yard or street, not back under the old slab. Last, the calendar. The National Weather Service dates the local rainy season from May 25 to October 10, so we check the subgrade again on pour morning and book hot summer pours early in the day. Keep in mind these map units come from an older USDA survey. Our site visit settles what's under your own lot.

What It Costs
Here are our typical ranges. On houses this young, the size of the addition and how it ties into the builder slab move your total the most.
| Job | Per sq ft | Typical project | What moves the price |
|---|---|---|---|
| Concrete driveways | $8 to $14 | $5,000 to $10,000 | Widening width, apron work in City right-of-way; tear-out adds $2 to $4 per sq ft |
| Concrete patios | $8 to $14 | $2,500 to $6,500 | Extending the builder slab, base fill on low ground, future screen room |
| Concrete sidewalks and walkways | $8 to $14 | $1,500 to $4,500 | Side-yard runs to the gate; short runs hit a job minimum |
| Stamped and decorative concrete | $14 to $24 | $5,000 to $16,000 | Pattern, color and sealer; borders cost less than a full stamp |
| Concrete slabs and foundations | $7 to $12 | $2,000 to $7,500 | Shed or equipment pads; thicker or monolithic slabs cost more |

Zone A pockets, wetlands and the $7,500 exemption
The FEMA National Flood Hazard Layer puts roughly a fifth of the Riverstone area in Zone A, a Special Flood Hazard Area with no published base flood elevation, and the rest in Zone X. Wetlands line the edges too. Those shares count open water like Curtis Lake, so they tell you nothing about one house. Look up your address on the FEMA Flood Map Service Center first.
Here's why. Florida's HB 803, effective July 1, 2026, lets owners request a permit exemption for qualifying non-structural work under $7,500 on a single-family home. It isn't automatic. You file, you wait for written approval, and the building official decides whether a concrete job qualifies. Properties in a flood hazard area are excluded. A small patio on a lot that sits fully in Zone X might be worth a request. If any part of the lot is in Zone A, that same patio takes the regular permit. Our Lakeland concrete permit guide lays out the full sequence.

From Peace River Drive to Grey Granite Way: aprons on City streets
Riverstone's streets are named for Florida rivers, springs and rock types: Peace River Drive, Salt Springs Lane, Dolostone Drive, Siltstone Street, Quartz Court, Grey Granite Way. The City's street centerline layer codes every one of them as City-owned. So the strip between your lot line and the curb is City right-of-way.
Widen all the way to the street and you change the apron. The City's Public Works Engineering page says any work in its right-of-way needs a Right-of-Way Use Permit before it starts. Residential driveways are processed by the Building Inspection Division and inspected by Public Works Engineering, with a pre-construction notification at least 48 hours ahead, and the apron has to meet the City's Engineering Standards Manual. If your back patio or side walk stays on your lot, you skip the right-of-way step. For the apron piece, confirm the rules for your street with Public Works before we pour.

Additions that suit a house from 2020: patios, widenings and pads
If the builder slab behind your house only covers the spot outside the slider, stretching it into a full Riverstone patio makes a good first project. Plan any future screen room now, since whatever sits on the slab later sets its thickness and edges today.
Widen a two-car driveway a few feet and you've got room for a third car or a trailer. Our Riverstone driveway page covers tying new concrete into the builder's slab with an isolation joint. Side walks and pads for a shed or AC unit come off our sidewalk and slab pages, a stamped border can dress up a plain edge, and we pour simple pool decks too. Pay HOA dues? Ask whether new exterior concrete needs the association's approval before you file with the City. We also pour in Hawthorne Ranch, Towne Park, Carillon Lakes, Lakeside Preserve and the Lakes at Laurel Highlands.
