Planning Commission continues 430 Main/429 Beale housing proposal after heated public debate

The San Francisco Planning Commission on May 10 continued consideration of a downtown project authorization for 429 Beale (also described as 430 Main Street), a proposed 84‑foot, nine‑story residential development by Tidewater Capital that would add up to 141 dwelling units, including 19 permanently affordable rental units.

Planning Department staff presented the project and described two alternatives it had explored: a double‑tower or “two‑building” scheme and a notched single‑building design intended to preserve light and air to the adjacent Baycrest courtyards. The department said none of the sponsor'proposed alternatives fully mitigated air‑quality and exposure concerns and recommended approval of a notched design with conditions.

Craig Young, representing Tidewater and Warhorse Cities, told the commission the sponsor had spent four years in neighborhood outreach and revised the proposal to include an upper‑floor notch. "This 4 year outreach effort has yielded nearly 80 letters of support," Young said, and described a design he said "maintains the previously mentioned community benefits package" while reducing the unit count slightly to address neighbors' views.

Neighbors who live in the Baycrest Towers and others opposed the project for reasons that included loss of sunlight and concerns about air pollution from the adjacent Bay Bridge. "We would really hate to see this open space boxed in and turned into a semi‑dark atrium," Cecilia Lim, HOA president at 201 Harrison Street (Baycrest), told commissioners. Supporters including local labor and nonprofit representatives testified the project would create housing and jobs and that the sponsor had provided community benefits.

Commissioners focused on a technical dispute: whether a two‑building option could deliver the same unit count and unit mix as the sponsor'proposed single massing without undermining feasibility. The department's feasibility sketch suggested a two‑building scheme could meet the program; the sponsor said the two‑building approach would eliminate roughly 20,000 square feet and about 28 units and would make the project financially infeasible.

Given conflicting analyses, Commissioner Richards moved to continue the item so staff and the sponsor could prepare direct, comparable floor‑plate and unit‑mix calculations for several alternatives (the sponsor'proposed notch, a 45‑foot notch alternative, and the two‑building scheme). After discussion the commission voted to continue the matter to May 24, 2018, by a vote of 5 to 2 (Commissioners Coppell and Moore opposed).

Next steps: staff and the project sponsor were asked to return with side‑by‑side floor‑plate and unit‑mix comparisons and a clearer statement of what would be lost or gained in housing, affordable units and square footage under the alternatives. The commission directed staff to clarify what documentation would constitute a "demonstration of infeasibility" if a sponsor claims a preferred alternative is not buildable.

Authorities and procedural context: the hearing proceeded under the Planning Commission's downtown project authorization rules and Planning Code exposure requirements; the project as presented required exceptions to dwelling exposure standards. No final approvals were made; the item remains on the commission calendar.
