New York’s SEQRA Reform: What It Means for Long Island Development
New York just made it easier to move certain housing projects through the environmental review process. For Long Island investors and developers, the change could have a meaningful impact on which sites make sense to pursue.
But in Suffolk County, there is an important qualifier: sewer access may matter more than the number of units.
In May, Governor Hochul signed the “Let Them Build” amendments to the State Environmental Quality Review Act (SEQRA) as part of the FY2027 budget. The changes, which took effect immediately, represent the most significant revisions to SEQRA since the law was enacted in 1975.
SEQRA requires state and local agencies to study the environmental impact of a discretionary action before approving it. In practice, that means completing an environmental assessment form for almost any project that needs a zoning change, a variance, or site plan approval. Larger projects also require a full Environmental Impact Statement (EIS), and the entire file becomes a public record that opponents can challenge under Article 78. The question on Long Island is which sites now qualify for an exemption.
Which Projects Qualify
The new exemption generally applies to housing projects that meet several requirements, including:
- Size: It can’t exceed 300 dwelling units inside an urbanized area as defined by the U.S. Census Bureau, or 100 outside one.
- Infrastructure: It must connect to an existing public water and sewer system by the time residents move in.
- Previously developed land: It must sit on previously disturbed land, meaning land altered by a building or other improvement at least two years before you file. That excludes coastal erosion hazard areas, recently farmed land, and FEMA flood zones, unless the town requires elevated construction. Outside urban areas, the site must also border a previously developed parcel.
- Commercial space: Non-residential use is capped at 20 percent of gross floor area.
- Single-family development: Single-family homes on acre-plus parcels don’t qualify on their own.
Depending on the exemption, the applicant may also need a Phase I Environmental Site Assessment or a certification of compliance with hazardous materials and remediation requirements.
New Review Deadlines
SEQRA used to have no firm deadlines. The reform adds three:
- 120 days for an agency to decide whether a project is exempt, counted from when it receives the application.
- One year to decide whether a non-exempt project needs an EIS, counted from when a lead agency is established.
- Two years to complete an EIS once one is required, for projects that need a permit.
The Governor has also directed the Department of Environmental Conservation (DEC) to prepare Generic Environmental Impact Statements for certain housing and renewable energy projects. That should help projects that still need review avoid paying consultants to redo the same analysis.
Why Sewers Could Be the Real Story in Suffolk County
About 70 percent of Suffolk County has no sewer service, and most properties rely on cesspools and septic systems that sit above the aquifer supplying every drop of Long Island’s drinking water. Because the exemption requires a connection to existing infrastructure, it reaches the sewered downtowns and station areas. An unsewered commercial lot in eastern Brookhaven or on the North Fork, however, most likely doesn’t qualify. That map will keep moving. Suffolk’s approved capital budget puts about $1.5 billion into wastewater infrastructure through 2029, and a parcel that comes into a sewer district goes from ineligible to potentially exempt.
For investors, infrastructure isn’t just a public-policy issue. It can directly affect the development potential and economics of a parcel.
What Hasn’t Changed
Towns still control site plan review, zoning, special permits, traffic studies, contamination testing, and whether there’s enough wastewater and drinking-water capacity to serve the project. Any of those approvals can be challenged under Article 78. A missed 120-day deadline also doesn’t approve anything automatically. If the agency misses it, your project isn’t exempt by default; your remedy is to seek relief in court, which costs time and money.
What Does It Mean for Investors?
- Development costs are heavily influenced by time.
- Every additional month can mean another month of carrying land, paying taxes, insurance, legal and consulting fees, while remaining exposed to changes in interest rates, construction costs and market conditions.
- That means reducing the length of the approval process can affect more than the project schedule. It can affect the project’s overall basis, hold period and projected return.
- For an investor, the question isn’t simply, “Is this project exempt from SEQRA?”
How We’re Looking at It
At Strata Alliance, we evaluate Long Island development opportunities with the full capital stack and development timeline in mind.
For a potential investment, we want to understand the fundamentals early: the parcel, zoning, proposed unit count, existing infrastructure, entitlement requirements and potential development timeline.
SEQRA eligibility is now another important piece of that analysis.
We would still evaluate a project with the full environmental review process in mind rather than assuming an exemption will be available. But where a site appears to qualify, the potential time and cost savings can become an important part of the investment thesis.
For Long Island developers, understanding which sites can take advantage of these changes may be just as important as understanding the law itself.
If you’re evaluating a Long Island development opportunity and want to understand how the new SEQRA rules could affect the investment, send us the parcel and proposed unit count. Contact us today, we’re happy to take a look.
