Woodmont Commons, Londonderry, NH

Woodmont Commons is a 603 acre mixed-use development with housing, office space, retail and restaurants, medical space, civic space, and open space. The PUD’s master plan, approved in 2013, divides the former orchard into 12 subdistricts, each with its own mix of street types, block types, building types, and more. The project includes 1,400 new housing units, some of which are age-restricted. Construction of the 20-year project began in 2018.

Tuscan Village, Salem, NH

Tuscan Village is a large-scale mixed-use district in Salem, NH on the site of a former race track. If the plans for the development are fully executed, the 170-acre site will contain 4 million square feet of development, costing more than $1 billion, and completed potentially by 2030. As of January 2023, the developers plan nearly 1,800 housing units on the site. Roughly 1,200 units were completed or under construction at the end of 2022.

Bloomington, IN

Bloomington, Indiana’s PUD base zoning district is a vehicle for allowing PUDs within the 80,000-person city. For a PUD to be permitted, property owners petition to change the base zoning of their land and submit a PUD plan, which triggers a series of public hearings and municipal staff reviews, and ultimately reviews by their Planning Board equivalent and their governing body. If any housing is built, at least 15% must be deed-restricted Affordable Housing for low-income residents. Much of the city’s recent housing production and notable investments in transit have resulted from a few large PUDs.

Cliff Street Retreat, Ithaca, NY

  • Not long after a custom metal fabricator vacated its small industrial space in Ithaca, NY, the property owner proposed to adapt the existing structure into a mixed-use development incorporating office, restaurant, residential, light industrial, and hotel uses. The industrial use was already non-conforming. The developer and city used the PUD zoning provisions to bypass the purely residential zone’s rules and take on this more ambitious project. The complexity of the site, existing building, and proposed uses required the PUD zoning provision, though the site (at 2 acres) is relatively small among PUDs. The PUD was approved and the terms of the PUD were incorporated into the zoning code itself. Incidentally, the thorough municipal review made the project eligible for State tax relief.
