Draft MEPA regulations aim to streamline environmental review for housing in Massachusetts

Yesterday Governor Maura Healey announced draft regulations intended to shorten the state’s environmental review timeline for certain housing developments. Under the current system, environmental review for large projects often stretches beyond a year. The proposal released on September 9 would allow qualifying developments to avoid preparing a full Environmental Impact Report. Instead, those projects could complete review using the shorter Environmental Notification Form. The administration has described the proposal as a way to reduce procedural delays while helping move housing projects through the approval process more quickly across Massachusetts.

Eligibility for the proposed 30 day review depends on several project characteristics. A large majority of the development must consist of residential use. The draft regulations require at least sixty seven percent of the project to be devoted to housing. Supporting commercial uses such as small retail space or childcare facilities would still be allowed. Projects must also meet minimum density standards that vary depending on the type of housing. The proposal sets a baseline of eight units per acre for single family subdivisions. Housing that contains two or three units must reach twelve units per acre. Multifamily development must reach fifteen units per acre or a higher density.

The regulations also limit how much previously undeveloped land may be altered as part of a project. In most situations the disturbance would be capped at five acres. That limit could expand to ten acres if the development includes a plan for tree preservation together with replanting measures designed to offset the impact of clearing. Location restrictions are included as well. Projects located in the state’s most severe flood or erosion hazard areas would generally not qualify for expedited review. An exception would apply where a proposal involves redevelopment that incorporates flood resistant design standards consistent with state requirements.

The draft regulations also link faster review to environmental performance standards. Projects would need to comply with the Massachusetts Stretch Energy Code in order to qualify. The proposal also excludes developments that require construction of new gas mains. Major interbasin water transfers would also disqualify a project from using the accelerated pathway. Traffic impacts must remain below three thousand daily vehicle trips. A higher threshold of six thousand trips would apply where the site is located near public transit and provides safe pedestrian access.

Several additional provisions are intended to streamline review for specific categories of projects. A single family home that only requires a wetlands permit from the Department of Environmental Protection would no longer trigger a full MEPA filing. Planning initiatives such as urban renewal plans that do not authorize a specific construction project would move through the shorter review process rather than a longer analysis. Certain ecological restoration efforts would also receive expedited treatment, including projects involving dam removal or restoration of former cranberry bogs.

The proposal preserves existing protections for environmental justice communities. Projects located within those areas would remain subject to additional public notice requirements together with expanded outreach obligations. Advance notice must be provided forty five days before filing. Project materials must also be made available with translation services where appropriate. The Secretary of Energy and Environmental Affairs would retain discretion to require a more detailed environmental review where additional scrutiny is warranted.

The draft regulations are open for public comment through October 31 of this year. The state has scheduled several virtual hearings in mid October to receive input from developers, municipalities, and members of the public. If adopted, the changes would represent a major update to the MEPA process and reflect the state’s effort to move housing production forward while maintaining environmental oversight.
