Portland, Maine, is reviewing a new residential development, Deering Village, which will change how the city manages density and environmental preservation.
Located at 410 Auburn Street, the project proposes 130 rental homes situated on a 4.2-acre parcel bordering North Deering Park.
The project, led by GreenMars Real Estate Services, is currently under site plan review with the Portland Planning Department. The development plan features 13 three-story buildings, each containing 10 units. The developer increased the project's capacity by using Portland’s LD 2003 density allowance—statewide legislation enacted in April 2022 and adopted by the city in December 2023. Before these density tools were applied, the site was zoned to accommodate approximately 25 homes.
This increased capacity is designed to fit the site’s natural geography. Rather than spreading construction across the entire 4.2-acre lot, the developers have clustered the housing units on previously disturbed areas. This strategic layout allows for the permanent preservation of roughly 80,000 square feet of wetland, which will feature a boardwalk for residents and park visitors.
“The wetland shaped the plan,” according to project documentation. GreenMars aims to provide a mix of studio, one-, two-, and three-bedroom units, noting that they expect the homes to be reasonably priced. The development is designed to be all-electric and energy-efficient, following the model established by the firm’s previous project, Stroudwater Commons.
The integration of high-density housing alongside conserved wetlands has presented specific engineering and access hurdles. Because the site plan is built around the land’s natural features, the developer has had to navigate complex infrastructure requirements, including ongoing coordination with the City of Portland to establish a property entrance through an existing sewer easement.
Footpaths are also planned to connect the new community directly to the entrance of North Deering Park, aiming to encourage pedestrian connectivity between the residential area and public green space.
The project changes urban planning for the neighborhood, as the city applied the LD 2003 density increases citywide rather than restricting them to specific zones. This approach has allowed for a much larger number of rental units on a single parcel than was previously possible under earlier municipal codes.
GreenMars, a firm headquartered in Portland, has a portfolio that includes other local projects such as Nasson in the Pines, Wilbur’s Woods, and Cape Commons. Their stated mission involves expanding housing supply by returning underused properties to productive use.
The next confirmed checkpoint for Deering Village is the conclusion of the site plan review process with the Portland Planning Department. Further details regarding the construction timeline and the final unit specifications will be determined as the project moves through the City of Portland’s planning and permitting regulatory stages.
