Clayton Plan Commission — February 17: A new 600-bed WashU dorm clears site plan review at 6500 Forsyth
The Plan Commission approved the site plan for a new Washington University residence hall on the South 40, with the design board signing off on the building the same night — both votes unanimous.
What happened
Clayton's Plan Commission met on Tuesday, February 17 and approved the site plan for a new Washington University dormitory at 6500 Forsyth Boulevard, on the university's South 40 campus. The project would demolish several structures and build a residence hall of roughly 600 beds, with amenity and service space, aimed at first-year and sophomore students. The commission approved the site plan with three staff conditions on a unanimous vote, and the Architectural Review Board — the same members, acting on the companion design review — then approved the building's design and materials, also unanimously. One resident spoke against the project online, but no board member opposed either motion.
What the board decided
- On the site plan, the Plan Commission took up the applicant's request, on behalf of owner Washington University, for site plan review of a new South 40 dormitory at 6500 Forsyth. Ryan Helle presented the staff report with a recommendation to approve subject to three conditions. Helen DiFate moved to approve with those conditions and Jim Arsenault seconded; the motion carried unanimously.
- On the companion item, the Architectural Review Board reviewed the design and materials for the same project and approved them as submitted, again on a motion by Helen DiFate, seconded by Jim Arsenault, that carried unanimously.
- The board approved the minutes of its February 2 meeting on a motion by Helen DiFate, seconded by Jim Arsenault.
Who was there
Chair Steve Lichtenfeld led the meeting, with members Helen DiFate, Jim Arsenault, Blair Kweskin and Jeff Morrisey — the newest appointee, welcomed at the outset — along with Susan Buse, the board's Aldermanic Representative. Member Chris Brennan was absent. Director of Planning and Development Anna Krane and planner Ryan Helle staffed the meeting.
What they debated
Staff told the board the proposal fits the South 40 overlay district's limits. At a maximum density of 94 beds per acre, the proposal would measure 86.8 beds per acre, and Ryan Helle reported that stormwater runoff, tree-canopy coverage and parking all met the code, with lighting designed to meet dark sky standards. The applicant's team made the case for the building: WashU requires first- and second-year students to live on campus, and the architects described a design inspired by the South 40 and the tradition of collegiate Gothic, organized along the campus 'spine' and a central courtyard, with masonry as the primary material to match the campus and improve safety by drawing student activity closer to the academic core.
Members raised concerns even as they supported the project. Jim Arsenault questioned whether concentrating new construction in the northeast corner of the South 40 cuts against the overlay's intent to focus activity on the campus interior, and walked through the bed-count math: he said the South 40 already holds about 3,341 beds and this project would add 622, leaving little room under the 94-beds-per-acre cap. He also noted that the overlay itself discourages the kind of traditional styling some critics wanted:
specifically states that new buildings should avoid neoclassicist or revivalist styles— February 17, 2026 — Meeting Transcript [#q3b2efd32]
Other members pressed the demolition of two older homes on the site, including a building tied to the campus's history. The applicant's team said the structures are not formally protected, that due diligence was done to salvage and preserve their history, and that the former chancellor lived in the home only about four months. On the building's relationship to Forsyth Boulevard, Chair Steve Lichtenfeld acknowledged it sits somewhat closer to the street than older buildings, but concluded:
I don't think that sets a precedent, but I'm not too concerned about this— February 17, 2026 — Meeting Transcript [#qbeadd112]
In context
After the two votes, the board stayed for a discussion session — no action — in which Director of Planning and Development Anna Krane walked members through the Clayton 2040 comprehensive plan and its implementation and a proposed overhaul of the city's Planned Unit Development rules. The idea on the table would replace the current public-benefit point system with a tiered structure — base, elevated and premium — that scales what a developer must offer to the size of what they want to build. Members discussed how to keep promised public benefits — open spaces, retail, sustainability features — from being offered on paper and not delivered, a recurring frustration with past projects. Staff plan to bring draft regulations back to the board.
Public comments
The minutes record that no members of the audience elected to participate in the open forum. On the 6500 Forsyth item, the minutes note that public comments were heard; the transcript shows one resident speaking online in opposition. He argued the dormitory is too blocky when seen from the sides along Forsyth and would set a new precedent for how close and how tall campus buildings sit to the street, and objected to demolishing the older homes on the site rather than reusing them. The board approved the project after hearing the comment. (The resident's name appears only in the meeting transcript and is not used here; see the source notes.)
