Planning commission backs staff plan to study higher densities in R‑3 district, asks for targeted additions

The Environmental Planning Commission on Feb. 19 recommended that staff study higher densities in the city’s R‑3 zoning district and asked for targeted additions to the set of change areas staff proposed.

The commission’s discussion focused on three decisions staff asked for guidance on: whether the identified change areas reflect council goals and criteria; what density options to analyze for those areas; and whether some R‑2 parcels should be integrated into R‑3. Staff framed the proposal around 14 draft change areas selected to meet council direction to focus on large parcels, transit access, and “affirmatively furthering fair housing.”

“This item is regarding increased densities in the R3 Zoning District,” Advanced Planning Manager Eric Anderson said in his presentation. He told the commission the project began in 2020 and that staff’s prototype and feasibility work found six‑ to seven‑story buildings — at roughly 75–135 units per acre — were necessary for financially feasible development at many parcels under the assumptions used in the analysis.

The staff report presented three density approaches: Option 1 would apply a six‑story R3‑D2 subzone as base density; Option 2A would apply a four‑story R3‑D1 base and rely on state density bonus incentives to reach higher effective densities; and Option 2B would leave base densities lower and create a local bonus to reach the prototype densities. Staff described risks with a local bonus, including uncertainty about how evolving state law would treat local programs.

Public comment was split. Nearby residents raised parking and cut‑through traffic concerns for Del Medio/Delmideo site areas, asking staff to account for existing street capacity and current parking use. Local housing advocates and YIMBY groups urged higher base densities, including rezoning some R‑2 areas and adding parcels well‑served by transit. Robert Cox, representing the steering committee of Livable Mountain View, said the staff approach generally “balances the desire for new housing production with the consideration of transition to existing residential neighborhoods.”

Commission discussion ran more than three hours. Commissioners repeatedly asked staff for clarity on how the proposed change areas were selected from the R‑3 district, how feasibility assumptions were built (including unit sizes and parking assumptions), and how the city’s replacement requirements for rent‑stabilized units under state law would be enforced in redevelopment. Staff repeatedly said several follow‑up steps are needed — including CEQA scoping and a more detailed standards package — before any ordinance would be drafted.

On policy direction, the commission gave staff a majority mandate to proceed with the staff framework and to study Option 2A (a four‑story R3‑D1 base with the potential use of the state density bonus) as the overall preferred density approach, while reserving the option to permit higher densities in specific areas. The commission specifically asked staff to: (1) study the R3‑D1 approach broadly; (2) treat Del Medio South differently — either by keeping its current higher density or by applying an R3‑D2/R4 scale rather than downzoning it; and (3) add and analyze additional parcels near Central Expressway/Moffett Boulevard and around the Mountain View Transit Center (including parcels within walking distance of transit and Central Expressway) for possible inclusion in the change areas. Commissioners also supported creating transition areas (the pink “buffer” areas staff displayed) to reduce abrupt height/density changes next to single‑family neighborhoods.

Commissioners stressed the need for careful standards to preserve neighborhood transitions, and raised uncertainty about how much of the city’s R‑3 zone would in practice be redevelopable under the evolving state density bonus law. Economic consultant David Bergman (Lisa Wise Consulting), who presented the prototype analysis, described the feasibility work as “abstract at this level” and noted results depend sharply on project‑specific decisions such as parking type (surface vs. podium vs. subterranean), unit mix and construction method.

The commission did not adopt an ordinance or a final map; its action constituted guidance to staff for next steps. Staff said the council will be asked for direction on the same set of questions on March 25 and that the project will proceed with environmental review, standards drafting and additional neighborhood outreach after council direction. Anderson reiterated that CEQA documentation requires a parcel list and density range to begin scoping, which is why the commission’s guidance matters at this stage.

Planning director Christian Murdoch told the commission staff will return with refined alternatives — including detailed form‑based standards, transition treatments and feasibility work — and that the R‑2 update will be developed in parallel so the relative capacity of R‑2 and R‑3 can be compared.

The EPC’s guidance will shape the formal drafting phase but does not itself change zoning. Staff said any ordinance would come back to the EPC and then city council for formal votes after environmental review.

Why it matters: the R‑3 district contains a large share of the city’s multifamily stock and many rent‑stabilized units; changes to allowed density, development standards and replacement requirements could materially affect housing production, displacement risk and neighborhood character.

Next steps: staff will revise maps and technical analyses and present options to the city council on March 25; the project will then proceed with CEQA scoping, additional outreach and standards drafting.
