Planning & Transportation Commission - May 13, 2026

Commission recommends revised stream-corridor rules

The Planning & Transportation Commission voted 6-0 to recommend that City Council adopt a revised Stream Corridor Protection ordinance. The proposed framework uses a 25-foot streamside setback in the urbanized area and generally a 150-foot setback in the Baylands, open-space and non-urban areas, subject to the commission’s recommended relief for Residential Estate-zoned properties.

The commission selected an alternative that would use Residential Estate zoning, rather than an ephemeral-stream determination, as the trigger for a reduced setback. It also recommended limiting an exemption for properties separated from streams by streets, paved public trails or service roads to the urbanized area. Members asked staff to clarify the ordinance’s geographic terminology and restrict the flood-wall exemption to properties directly abutting a qualifying wall.

For Edgewood, the commission recommended allowing ornamental landscaping and exempting fences alone from slope-stability requirements, including the five-foot fence setback from the top of a stream bank. Staff had recommended retaining the slope-stability safeguards to protect bank integrity, preserve maintenance access and account for outside-agency easements.

Public comments reflected broad support for protecting streams but disagreement over effects on individual properties. Edgewood speakers sought relief for security fencing and landscaping, while residents around Esther Clark Park and Palo Alto Hills requested an objective reduced-setback standard. Environmental speakers generally favored the Residential Estate zoning alternative over broader relief based on ephemeral streams. Staff will revise the ordinance before a City Council hearing expected in the third quarter of 2026.

Planners support larger ADUs but defer separate sales

The commission unanimously recommended updating Palo Alto’s accessory dwelling unit and junior accessory dwelling unit rules to conform with state law. In a separate 6-0 vote, commissioners recommended increasing the maximum ADU size from 1,000 to 1,200 square feet. The underlying ordinance also addresses owner-occupancy rules, short-term rentals, impact fees, appeals and application-review timelines.

Commissioners stopped short of supporting a provision that would allow as many as three ADUs to be sold separately as condominium units. By a 5-1 vote, they recommended that City Council not advance separate sales at this time and revisit the issue when more information is available from other jurisdictions. Cari Templeton cast the sole no vote on that recommendation. Junior ADUs would not have been eligible for separate sale.

Public speakers generally supported both the larger size limit and separate sales, saying the options could create smaller ownership opportunities, help homeowners finance construction and allow older residents to remain in Palo Alto. Commissioners also discussed potential housing benefits but raised concerns about developer speculation, limited implementation data and unintended consequences as state ADU law continues to change.

The recommendations are expected to reach City Council at a hearing targeted for Sept. 14, 2026. City Council will decide whether to adopt the ordinance, including the larger size limit, and whether to pursue the separate-sale option.
