Background

Gregg Lake Beach Park, located at 220 Gregg Lake Road, comprises about 1.9 acres and includes a public swimming beach, a bathhouse, a picnic and recreation area, a parking lot and a public boat launch. In 2023, the Town of Antrim received funding from the State of New Hampshire to improve the public boat launch at Gregg Lake Beach Park. Matching funds were approved at the Antrim Town Meeting on Thursday, March 14, 2024. This project must be fully completed by July 31, 2024. We prefer the work to be completed before June 15, 2024, to reduce restrictions on public access to the lake.

Scope of Services and Description of Work

The goal of the Gregg Lake Public Boat Launch Improvement project is to stabilize the boat launch area to prevent further erosion of the ramp and parking areas and depositing of sediment in the lake, using best management practices that make it easier for recreational users to safely access the lake, while blending in with the park’s rural natural habitat.

A 12-foot-wide central boat ramp will be constructed of flexible plantable concrete mats, such as Drivable Grass, with gravel infill, starting at the road and reaching approximately 54 feet to within one foot of the high-water line. One section of chain-link fence by the road on the east side of the ramp will be removed to allow the central ramp to be shifted approximately six feet to the east to facilitate use of the parking spaces on the west side.

For the parking areas and ramp edges, the flexible plantable concrete mats, which allow for water infiltration and root penetration while also providing a solid surface for vehicles to drive on will also be used, but planted with grasses and short native plants that can handle some traffic. On each side of the central ramp, a 6-foot-wide strip of planted concrete mats will reach 16 feet from the road to the parking areas. The parking area to the west of the ramp will consist of 3, 10-foot-wide by 50-foot-long trailer parking spots for a total area of 50 feet (east-west) by 30 feet (north-south). The parking area to the east of the ramp will consist of 3, 10-foot-wide by 54-foot-long trailer parking spots for a total area of 54 feet (east-west) by 30 feet (north-south). At the lakeshore edges of the ramp, planted concrete mats 6 feet wide by 4 feet long will stabilize both sides.

Bases will be prepared under the permeable paving materials as required to allow maximum stormwater infiltration, and grading will direct stormwater away from the boat ramp.

Low raised berms will be installed with native vegetation along the lakeshore on both sides of the ramp to limit further erosion, and the areas around the existing kayak/paddlecraft racks will be revegetated.

Stormwater runoff from the road will be directed to a vegetated swale in the northeast corner of the boat launch area.

A 6-foot by 4-foot area of permeable pavers with vegetative infill on the northeast side of the entrance will be prepared as a space for an informational kiosk.
