NLWC Raises Critical Water Quality Issues with Surfside Crossing’s 40B Proposal

Anna Day • January 29, 2025

The remand hearing for Surfside Crossing’s 156 unit 40B development is ongoing before Nantucket’s ZBA, and the deadline for the public hearing has been extended to February 21st. Last fall when the remand hearing began, the NLWC hired two professionals to assist us with reviewing the current plans for the 18 condo buildings and onsite development. One of our consultants, Sean Reardon, is a professional engineer who has worked with a number of ZBAs across the state assisting as their peer review engineer on 40B projects. The second, Scott Horsley, is a renowned water quality specialist who has helped us take a closer look at the implications of the proposed development on the island’s groundwater and public drinking water supply. They discovered some critical issues with the project’s design that have raised major concerns with the ZBA.

What Reardon and Horsley’s reviews have brought to light about the proposal is a lack of compliance with the state’s Stormwater Management Standards as well as the MA Drinking Water Regulations and an important provision in Nantucket’s Zoning Bylaw governing development within our Wellhead Protection District. 
Almost the entire 13.5 acre Surfside site lies within this environmentally sensitive area. The Wellhead Protection District was established to protect the region of our aquifer that contributes to the public water supply wells (this region is also called a Zone II region). 

The bylaw provision sets a standard that only up to 15% of a property within the Zone II can be developed as impervious surfaces unless it can be demonstrated that at least 95% of the stormwater is properly recharged into the aquifer AND there will be no degradation to groundwater quality. I
mpervious surfaces typically include things like parking lots, roadways, and buildings, where precipitation is impeded from naturally infiltrating into the ground. Instead it runs off the surface carrying pollutants or contaminants with it. The aggregate amount of impervious surfaces proposed by project developers is three-and-a-half times (3.5x) the limit imposed by the Drinking Water regulations and the Nantucket bylaw. Modern stormwater infrastructure can do a great job of managing flooding by infiltrating run off into the ground, but without proper pre-treatment many of these contaminants are carried directly into our groundwater as the natural filtration provided by vegetation and organic soils have been eliminated.

To date, the developers have made no attempt to address these critical issues and have only responded with attempts to justify their lack of compliance with this standard based on a lack of proper enforcement at other sites within our Zone II on the island. 
The scale of this project and magnitude of disturbance, clearing 13 acres of natural vegetation and converting 6.48 acres (52% of the site) to impervious surfaces, warrants more effort than simply relying on what others have gotten away with elsewhere. As Nantucket continues to develop throughout the mid-island area, much of which is within our Zone II, it is critical that we take better care to ensure that these developments do not cumulatively degrade our public drinking water supply, and implement the state and local standards for managing impervious surfaces and stormwater properly.

We will continue to advocate against the proposed project, which fails to meet state standards for stormwater management and does not adequately prevent the pollution of our public water supply.

We encourage all community members to participate in the public hearing and raise any concerns you have about the project with the Zoning Board of Appeals. The ZBA is scheduled to hear this matter on Feb 3, from 1pm - 4 pm, on Feb 4, from 11 am - 2 pm, and on February 19, from 1 pm - 4 pm.

Last week, the appeal hearing for the Surfside Crossing 40B development was conducted remotely by the state’s Housing Appeals Committee (HAC). The NLWC participated as an intervening party to defend clean drinking water for Nantucket. The proposed 156 condo unit development on 13.6 acres known as Surfside Crossing (SSX) off of South Shore Rd is of inappropriate density (13 x the local zoning) and would compromise our drinking water supply. Following the comprehensive permit review by the Zoning Board of Appeals (ZBA) that took place throughout last fall and winter, the application for SSX was unanimously denied by the ZBA. This denial was subsequently appealed to the state by the developers, Jamie Feeley and Josh Posner, in April of this year. During the comprehensive permit review last year by the ZBA, the NLWC hired an engineering expert and water quality specialist to review the project’s stormwater management plans. The review and testimony of these experts revealed that the stormwater infrastructure proposed for the Surfside Crossing development does not meet the specific state and local standards for projects within the Nantucket Wellhead Protection District (the area where groundwater contributes to the public water supply wells), or for projects that meet the state’s criteria as a Land Use of Higher Potential Pollutant Load (LUHPPL). Given recent public well contamination by elevated PFAS levels, it has become abundantly clear that these standards are incredibly important to uphold, especially for a project of this scale within our public water supply recharge area. The local ZBA agreed with the importance of protecting clean water , and asked the developers to address the stormwater management design to ensure that it meets state and local standards and protects not only the residents and direct abutters of the development, but the public water supply that we all share. Unfortunately, the developers refused to make any changes to their proposed design, in part because it would require a reduction in the number of units to make the necessary changes, and in part because they have already installed their stormwater infrastructure, “at risk”, without the benefit of a permit, and without a water quality certificate issued by the Water Commission as required in Nantucket’s Zoning Bylaw. They simply do not want to have to take it back out of the ground. Based on concerns for the health of the community’s drinking water, as well as other concerns relative to public safety and traffic, and considering the developers’ refusal to consider any changes whatsoever to their proposal, the ZBA unanimously denied the project. As an intervening party in the developers’ appeal of the ZBA’s decision, he NLWC has been working closely with the counsel for the Town of Nantucket’s ZBA, and the residents group, Tipping Point, to file written testimony from the NLWC’s engineer, the ZBA’s engineer, and several water quality and PFAS subject matter experts. During the HAC hearing last week, the developers’ counsel chose not to cross-examine any of these witnesses, and so their written testimony stands unchallenged, leaving the hearing office no basis to question their expert opinions. This hearing on the Surfside Crossing matter follows a similar appeal by developers in the Town of Walpole for a Chapter 40B development that was also denied by the Town’s ZBA due to similar concerns over improperly designed stormwater infrastructure, and the degradation of the Town of Walpole’s public water supply. As we await a decision from the HAC, we are grateful to Nantucket’s ZBA for their due diligence during the public hearing process, and for the opportunity to prepare for the appeal hearing in partnership with Town Counsel for the ZBA, as well as the residents’ group Tipping Point.

In April 2025, the Nantucket Land & Water Council (NLWC) joined over a dozen Nantucket residents —including members of the Nantucket Coastal Conservancy, property owners in Quidnet, and the Greenhill family—in filing a Request for a Superseding Order of Conditions (SOC) with the Massachusetts Department of Environmental Protection (MassDEP). This action was taken in response to the positive Order of Conditions issued by the Nantucket Conservation Commission on March 20, 2025, which approved a three fold expansion of the ’Sconset Bluff Geotube project.

If you're concerned about PFAS (per- and polyfluoroalkyl substances) in your drinking water, filtering your water is an easy step you can take to reduce exposure. There are effective filtration options that can significantly reduce PFAS levels in your tap water.  Below, we've outlined a few types of filters that are known to reduce PFAS, along with the certification to look out for, to help you choose the right one for your needs and budget.
