Sonoma County pushed a long-stalled Roseland promise closer to reality yesterday, signing off on a community-led blueprint for the civic heart of Tierra de Rosas and clearing the way for the project’s commercial square. Supervisors also advanced construction on the one-acre Plaza Permanente park, which county staff and partners still say is on track to open by early September 2026. The approvals keep MidPen Housing and other developers moving on the master plan while a local coalition starts figuring out how the civic space will actually work on the ground.
Coalition pitches $25 million community hub
Health Equity Rising, which is working under the fiscal sponsorship of Sonoma CAN, has put in a proposal to lead the civic parcel that leans heavily on a culturally responsive, community-guided process and pegs the total project budget at roughly $25 million. The group’s response to the county’s request for information frames the site as a neighborhood community hub and calls for an initial planning and feasibility phase to sort out financing, operations and programming.
Those materials are included with the county agenda. As outlined there, the submission describes a multi-sector coalition and a design process that lets local residents help shape what the civic space becomes in practice. Sonoma County.
Housing keeps grinding forward
On the housing side, MidPen Housing reports that Casa Roseland, the affordable housing phase of Tierra de Rosas, is slated to wrap construction in early summer 2026, with resident move-ins expected to start in June if the schedule holds. The affordable component will bring about 75 income-restricted units to Roseland, while the broader master plan calls for up to 100 market-rate units and community space. MidPen Housing.
Board sign-off and a commercial RFP
At its July 14 meeting, the Board of Supervisors authorized the county’s Community Development Commission to enter into an agreement with Community Action Partnership of Sonoma County, the fiscal sponsor for Health Equity Rising, to carry out due diligence on the civic parcel. Supervisors also approved issuing a request for proposals for the commercial parcel and signed off on a short extension of the professional services agreement with MidPen Housing to keep predevelopment work on track.
As reported by The Press Democrat, county leaders framed the moves as a concrete step toward delivering long-promised neighborhood benefits for Roseland residents who have been hearing about Tierra de Rosas for years.
Plaza progress and playground cash
County documents show a change order that folds the Plaza Permanente scope into the existing Tierra de Rosas construction contract, with roughly $2.43 million identified for plaza infrastructure, hardscape, play features and a modest owner contingency. The one-acre public plaza is designed with a lawn, shaded seating, play equipment and basic amenities for families.
Federal community project funding has given the playground a boost, too. Rep. Mike Thompson’s office says $250,000 was secured for playground equipment at the plaza.
Next up is the coalition’s planning and due diligence period, which is intended to lock in a financing and operations plan for the civic parcel. That will be followed by a competitive RFP for the commercial site and an eventual return to the Board of Supervisors for any land-use or real-estate approvals. If the current timeline sticks, Tierra de Rosas will start to show off both visible public space in Plaza Permanente and new housing in the months ahead, the sort of neighborhood infrastructure Roseland advocates have been pressing for since the project was first floated.
