The empty lakefront lot at the corner of Routes 6 and 6N is about to change for the first time in years. It may not look like progress at first. The Town of Carmel's first construction phase at Swan Cove is a large load of fill dumped on the site and left there for months. Town officials hope to start it before the end of the year. When it starts, you won't see a parking lot, a pier or a kayak launch. You'll see dirt.
That mound is the most important thing to happen on the property since the town bought it. The soil under Swan Cove is what has held the project back from the start. Fixing it takes weight, water draining out, and time, and none of that can be hurried with a bigger budget or a faster vote.
The Ground Was Always the Problem
According to Mahopac News, Carmel paid $1 million in 2018 for the Swan Cove property at the Routes 6 and 6N intersection, which the paper describes as roughly half an acre. The plan was a small public park on Lake Mahopac that would also help with downtown's long-running parking shortage. Eight run-down bungalows overlooking the lake were torn down to clear the land, according to Mid Hudson News. In 2019 the town added four Tompkins Bank parcels, about an acre in total, for $395,000.
The plans kept changing after that. Officials dealt with flooding, drainage, engineering, environmental reviews and cost. They also argued over how much of the site should be parking and how much should stay green. A 2022 conceptual plan reported by The Examiner showed 93 municipal parking spaces, 18 of them set aside for the neighboring bank. That was a concept and was never final.
Then the land itself caused another delay. In 2025, a state Department of Environmental Conservation inspector found cattails on the property and classified it as wetland. That meant more assessment and permits, and a planned bid was put on hold, as Mahopac News covered that summer. Mid Hudson News reported on October 12 that the issue was resolved. Supervisor Michael Cazzari said the town's attorney contacted the state directly, the town submitted its SEQRA determination, and that cleared the way to final design and bidding.
The cattails tell you something. Wet ground grows wetland plants, and the same waterlogged soil that grew them is the reason a paved lot can't simply be built on top.
How a Surcharge Fixes Soft Ground
Councilman Rob Kearns explained the problem plainly at a September 16 Town Board meeting, as quoted in Mahopac News. He said the soils under the site are "peaty, if you want to call it as such." In another interview with the paper, he said that without stabilization, pavement and other improvements could settle and buckle.
Engineers call the fix a surcharge program. Here is how it goes, based on the town's description:
- Load the site. A large amount of fill is placed on the property. Its weight presses down on the soft soil underneath.
- Squeeze out the water. The pressure compacts the peaty layer and pushes out trapped water. The point is to keep the site from flooding every time it rains hard.
- Monitor it. Geotechnical probes track how the ground responds. Town Engineer Richard Franzetti estimated four to six months, depending on what engineers find once the work starts.
- Scrape it off. "We're going to let it settle. We're going to scrape it off, and then the next phase will be to actually build out the park," Kearns told the Town Board, according to Mahopac News. He also said that soil can then be used to build the park and parking area.
The mound itself is the treatment.
What Changes at the Corner Once Work Starts
The Town Board voted September 2 to advertise for Phase 1 bids. Bid documents went out September 23 for a bidding period of about five weeks that ran through late October. Town officials hope to have Phase 1 underway before the end of the year.
Franzetti described what the corner will look like for people who use it while the work goes on:
| Spot | During the surcharge |
|---|---|
| Swan Cove site | Access restricted |
| Chamber Park | Open to pedestrians, but parking could be difficult |
| Tompkins Bank driveway | One-way traffic, entering by the driveway near the gas station, going behind the bank, and exiting at the existing traffic light |
| Bank parking | Some spaces kept for the bank and its employees, but limited |
Chamber Park is the part most people will notice. The Town of Carmel describes it as a waterfront park on Lake Mahopac at the corner of Routes 6 and 6N, with a gazebo, fountain, playground, walking paths and benches. It is a carry-in, carry-out park open dawn to dusk all year. All of that stays open during the work. If you usually drive to the park, plan on the parking being harder to find.
Who Is Running It, and What It Costs So Far
The Phase 1 team is mostly in place. On September 16 the Town Board hired Woodard & Curran for engineering and bid-assistance services, at a cost not to exceed $13,800. At its October 14 meeting, the board considered Franzetti's recommendation to hire GeoDesign, the project's engineer of record, for construction management. GeoDesign was the lowest of three proposals at $63,795. The higher proposals included hundreds of hours of on-site staff time. GeoDesign would instead provide geotechnical services and coordinate with Woodard & Curran.
Franzetti recommended an overall construction management budget of no more than $100,000. That would cover GeoDesign plus about $22,405 more for Woodard & Curran site services, so the board wouldn't have to approve repeated funding requests as the work goes on. Board members asked for assurance that Woodard & Curran would visit the site only when the town asked. Franzetti confirmed the town would control those visits.
Those figures are for oversight. The firm that will actually place the fill had not been named in the town's reporting as of late October. The board also said it was still working out how to pay for Phase 1, with contingency funds, parkland funds and grant money all possible. Members planned to consult town comptroller Mary Ann Maxwell before deciding.
Kearns kept coming back to cost during the September meeting. As Mahopac News reported, he said:
"We don't want to overspend on this property, but we also want to be able to provide an asset for the community. It is lakefront property."
The project has outside money too. U.S. Rep. Mike Lawler secured more than $2 million in federal funding for clean-water infrastructure tied to the downtown redevelopment. That includes stormwater improvements meant to reduce runoff into Lake Mahopac.
The Park Waits on the Soil
Everything people have been waiting for comes in Phase 2. As of September, the town's vision still included a municipal parking lot, green space, a fishing pier, a kayak launch and a pedestrian bridge connecting Swan Cove to Chamber Park. Kearns said the kayak launch would be for Carmel residents, and the town would develop a way to verify residency, possibly a vehicle sticker or a similar permit. He also said cost will help decide the final layout, and that some cost estimates circulating publicly are inaccurate.
Phase 2 design was about 70 percent complete at the end of September. The rest is partly waiting on permits. Franzetti said the design should be finished before the stabilization period ends, so the town can seek Phase 2 bids during the months the fill is settling. "Phase 2 would start immediately following the completion of Phase 1," Kearns said in the same Mahopac News report.
The town hasn't set a Phase 2 date, but you can work out a rough window from its estimate. If the fill went down in December and the soil needs the full four to six months, Phase 2 couldn't start until sometime between spring and early summer of 2027. Any delay in starting Phase 1 pushes that later. Kearns, who works in construction management, is set to take office as town supervisor in January, according to Mahopac News. He has said he meets regularly with the project's engineers.
Once the mound goes up, the timeline depends on how fast the soil drains, and the probes will measure that. The next real milestone is the day the fill is scraped off.
