2026 Urban Exploration Trip: Seaport

The Downtown Partnership takes invited members on an annual Urban Exploration Trip, highlighting projects in a particular city that demonstrate lessons learned that can be applied to active development projects in St. Pete. This year, we are going to Boston to see the Boston Public Gardens, Downtown Crossing, the Rose Kennedy Greenway, and Seaport. Please find more information about the Boston Public Gardens below.

BOSTON SEAPORT

History

The neighborhood first began to take shape in the 1850s as an industrial zone built on landfill, largely shaped by train tracks, freight terminals, and industrial fishing piers. In the early 1900s, the area came alive with ships delivering goods to nearby factories, making it one of Boston's busiest commercial ports. But the mid-1900s brought steep decline — factories shut down or relocated, and the area became known for empty lots and abandoned buildings.

Beginning in the 1990s, two unprecedented public investments — the Big Dig and the Boston Harbor cleanup — sparked new interest in the largely vacant waterfront property just a short distance from the Financial District. The $14.6 billion Big Dig buried the formerly elevated I-93 interstate, which had previously cut off the waterfront from the rest of the city, and extended I-90 eastward through the Seaport all the way to Logan Airport.

In addition to the Big Dig, the construction of the John Joseph Moakley Federal Courthouse at Fan Pier and a new convention center helped set the stage for private development. The Fort Point warehouses became home to tech startups, art studios, and creative businesses drawn by lower rents and open floor plans. ‍

The Innovation District

In January 2010, Mayor Thomas Menino launched an initiative dubbed the "Boston Waterfront Innovation District" — a plan to take approximately 1,000 acres of underdeveloped South Boston waterfront and create a work/live/play environment designed to attract technology and innovation companies.

The site was master planned by Morgan Stanley and Gale International starting in 2006, with WS Development joining in 2007. By 2015, WS Development assumed the role of lead developer and completely redesigned the master plan, with the philosophy that "this is not a development project; this is the creation of a neighborhood."

WS Development is a Boston-based private real estate company with deep roots in the region. While the company built its reputation primarily as a retail and mixed-use developer across New England, its involvement in the Seaport District has elevated it into a different league entirely — becoming the steward of what is now the single largest active private development project in Boston's history.

While WS Development isn't the only developer operating in the Seaport, the company became a dominant force in 2015. Navigating the project required addressing decades of infrastructure planning, layered regulatory requirements, complex agreements with multiple public entities, and extensive environmental and zoning challenges — including land control issues, infrastructure relocation, and multiple layers of public approvals — all rooted in the legal legacy of the Big Dig's Central Artery/Tunnel Project.

WS transformed 33 acres of land, composed of 7.6 million square feet of residential, hotel, office, retail, entertainment, civic, and cultural uses, as well as signature public open spaces. The project represents the single largest active development project in Boston's history. The Seaport is now home to an ecosystem of more than 350 companies, from global leaders in technology and biotech to groundbreaking startups, following a decade of development and $22 billion of public investment.

The Philosophy: Creating a Neighborhood, Not a Project

From the outset, WS articulated a philosophy that distinguished its approach — at least in aspiration — from typical corporate real estate development.

"We try always to remember that this is not a development project; this is the creation of a neighborhood," said Yanni Tsipis, senior vice president of Seaport development at WS Development. "This is a piece of a great American city, and great cities are composed of great streets, public places, and social spaces that happen to have buildings built between them. That is a very important philosophy for us as the stewards of the Seaport."

In assuming stewardship of the remaining undeveloped blocks, WS Development saw the opportunity and the responsibility to elevate the neighborhood to standing among those of other world-class cities — by cultivating activity, vitality, and a strong neighborhood identity. The Public Realm: Harbor Way and the Paseo

The centerpiece of WS's public realm strategy is Harbor Way — a pedestrian promenade designed to knit the Seaport together and connect it back to the water. Harbor Way is a linear promenade and central public park that carves pathways through the site. Landscape architect James Corner — whose firm is known for New York City's High Line — calls it "a pedestrian armature" designed to connect the city to the harbor. "The tendency for developments at this scale is the developer is always wanting to internalize the project, to turn it inwards," Corner explained. "I always find those places bereft of urban life. They're often empty and sterile simply because they're not connected to anything."

Central to the master planning effort was creating a landmark "urban room" — with Harbor Way Square Park at its heart featuring a large central lawn — and a 21st-century neighborhood experience, with 39% of the total project area exclusively devoted to pedestrian-only open space. The individual buildings also contribute to public life at the street level. One Boston Wharf features the Boston Wharf Paseo — a street-level interior public promenade lined with shops, cafes, and public art installations leading from the Fort Point Channel Landmark District to a new one-acre public space called The Rocks at Harbor Way.

WS has positioned sustainability as a defining feature of the Seaport portfolio. One Boston Wharf is a 707,000-square-foot, 17-story mixed-use building that will be Boston's largest net-zero-carbon office building, reducing greenhouse gas emissions by more than 90% below code requirements and eliminating 5.1 million pounds of CO2 emissions annually.

The building features water reclaimation systems, air-source heat pumps, advanced energy recovery technology, and state-of-the-art building management systems. It also marks the first commercial placement of Sublime Systems' zero-carbon cement and has achieved LEED v4 Platinum certification. Buro Happold Amazon has leased the entirety of the office space, creating a total footprint of over 1 million square feet within WS Development's Seaport development.

One Boston Wharf also includes a long-planned performing arts center with a 500-seat performance venue and a more intimate 100-seat venue, catering to local Boston arts groups — one of the few major civic spaces in the fast-growing Seaport district.

The Criticisms: A Gleaming, Unequal Neighborhood

For all its ambition, the Seaport under WS Development and its predecessors has attracted criticism. The Seaport has been criticized for its inhuman scale, lack of civic spaces, poor transportation and connections to the rest of Boston, and lack of affordable housing. The growth has also all but eradicated what was once a vibrant arts community in the adjacent Fort Point neighborhood.

The deepest criticism is racial and economic. The city redeveloped the Seaport District over the past decades, but never with an eye towards creating an integrated neighborhood. The results show: a largely white, largely affluent new neighborhood has risen in the city's midst. There are no schools and no homes priced within reach of the average Bostonian.

The district stands as perhaps the region's most vivid illustration of what a luxury-dominant development corridor delivers: glass towers, high-end fitness studios, trendy restaurants, and a conspicuous absence of everyday fixed infrastructure.

The Bottom Line

WS Development has delivered something genuinely impressive by the metrics of private real estate development — a massive, architecturally ambitious, increasingly sustainable mixed-use district built from scratch on what was once a wasteland of parking lots. Their commitment to public realm, Harbor Way, and net-zero sustainability sets real benchmarks for urban development.

Today it is home to major companies like Amazon and Vertex Pharmaceuticals, alongside residential developments, cultural institutions, and modern architecture that has reshaped the city skyline. In short, it went from a forgotten industrial wasteland of parking lots to one of America's most prominent urban redevelopment success stories — driven by public infrastructure investment followed by a wave of private development.

But the Seaport also represents the limits of what private development — even well-intentioned, thoughtfully managed private development — can achieve without stronger public policy mandates for affordability, equity, and integration. The neighborhood WS built is extraordinary for those who can afford it. The harder question Boston continues to grapple with is who it was actually built for.
