How West Islip’s 2024 Wetland Restoration Projects Are Raising Groundwater Levels—And What It Means for Your Basement
West Islip homeowners are experiencing an unexpected consequence from the area’s environmental progress: increases in aquifer recharge and sea level in response to climate change can increase water levels and stream flows, creating concerns for groundwater flooding of subterranean infrastructure in low-lying areas where the unsaturated zone is already thin. As the Town of Islip continues its ambitious Bay Shore ecosystem restoration efforts in 2024, many residents are discovering that environmental improvements can sometimes create new challenges for basement waterproofing.
The Connection Between Wetland Restoration and Rising Groundwater
The relationship between wetland restoration and residential groundwater levels is more direct than many homeowners realize. Wetlands sometimes are helpful in recharging groundwater, and wetlands frequently serve as groundwater discharge sites, thereby maintaining the quality and quantity of surface water supplies. When restoration projects successfully restore natural wetland functions, they can significantly impact local water table levels.
The Town of Islip has been actively engaged in comprehensive ecosystem restoration efforts. The Reserve extends across the southern portions of Nassau and Suffolk Counties and includes: the City of Long Beach; portions of the Towns of Hempstead, Oyster Bay, Babylon, Islip, Brookhaven and Southampton; and 28 villages. These restoration projects, while environmentally beneficial, are having unintended consequences for residential properties.
2024’s Major Restoration Projects and Their Impact
Several significant projects are reshaping the Bay Shore ecosystem in 2024. Project work began in March 2021 and is expected to be completed in 2024, including the Bay Park Conveyance Project, which strengthening our wetlands so that they can reduce the impact of increasingly frequent storms. Additionally, the county plans to use FEMA’s Integrated Marsh Management (IMM) method, which involves filling old grid ditches to restore the natural hydrology of the wetland. Filling these ditches raises marsh elevations, which improve growing conditions for native marsh grasses and improves tidal flow.
These restoration efforts are proving successful in their environmental goals. Biofiltration by shellfish is an acknowledged method of algae population control, which improves water quality, and the Town of Islip’s shellfish cultivation programs are expanding. However, the improved water retention and groundwater recharge capabilities of restored wetlands are creating new challenges for nearby residential properties.
Understanding the Groundwater Challenge
Long Island’s unique geological conditions make it particularly susceptible to groundwater-related basement issues. Many areas, especially in Nassau County, have naturally high groundwater levels, and the impacts of a rising water table may include an increase in the potential for subsurface structure flooding (subway tunnels, basements) or on-site septic system failure.
The New York State Department of Environmental Conservation has been studying this phenomenon extensively. The New York State Department of Environmental Conservation (DEC), in collaboration with the United States Geological Survey’s (USGS) New York Water Science Center, today announced the release of the Long Island Groundwater Sustainability Project (LIGWSP), the Island-wide groundwater model, and Phase 1 study and scenario results. Phase 1 focused on the aquifer system beneath Kings, Queens, and Nassau counties and provides valuable information about how the aquifer reacts under various scenarios, including sea level rise, drought, pumping, and more.
What This Means for West Islip Homeowners
For West Islip residents, the combination of successful wetland restoration and naturally high groundwater levels creates a perfect storm for basement water issues. An increase in the elevation of the water table (dashed blue line) may result in basement flooding and compromise septic systems. This is particularly concerning given that the above normal precipitation has brought the groundwater levels to near record highs in some parts of Long Island.
The signs of rising groundwater impact on residential properties are becoming increasingly evident. Homeowners may notice increased basement humidity, water stains on foundation walls, or actual water infiltration during heavy rainfall events. These issues are often exacerbated by loss of natural wetlands: development has reduced nature’s ability to absorb excess water, though ironically, the restoration of these wetlands can temporarily increase local water table levels as natural hydrology is reestablished.

For West Islip residents dealing with these emerging groundwater challenges, professional basement waterproofing west islip services have become increasingly important. For over 25 years, Diamond Masonry & Waterproofing has been the trusted name for masonry and waterproofing services. Anything from wet basements and foundation cracks to water damage, we’ve helped homeowners protect their homes with reliable solutions that last.
Comprehensive Waterproofing Strategies
Addressing groundwater-related basement issues requires a comprehensive approach. Interior basement waterproofing works well for managing water that’s already entering through foundation walls or floors – we install drainage systems and sump pumps to collect and redirect water. Exterior basement waterproofing prevents water from reaching your foundation in the first place through membrane systems and proper drainage.
The benefits of professional waterproofing extend beyond immediate water control. It is possible that basement waterproofing increases your home’s value and marketability. Buyers see a dry basement as a major advantage, it’s a sign that the foundation is in good condition and that the home is being properly maintained.
Looking Ahead: Balancing Environmental Progress and Home Protection
As West Islip continues to benefit from ecosystem restoration efforts, homeowners must adapt to changing groundwater conditions. We’ve protected sensitive wetlands, installed fish ladders, created new oyster reefs, advanced kelp farming and we are filtering polluted stormwater before it enters the marine environment. These environmental improvements are essential for long-term community resilience, but they require corresponding adjustments in how we protect our homes.
The key is proactive planning. Rather than waiting for basement water issues to develop, West Islip homeowners should consider professional waterproofing assessments now. We’ve built our reputation on permanent solutions, not quick fixes. When we assess your basement, you’re getting honest feedback about what’s causing your water issues and what it actually takes to solve them.
Taking Action
The intersection of environmental restoration and residential water management represents a new challenge for West Islip homeowners. While the community’s ecosystem improvements are creating a healthier, more resilient environment, they’re also changing local groundwater dynamics in ways that can affect basement conditions.
