Walnut Creek plans 6-lot subdivision with affordable housing amid zoning adjustments

In the heart of Walnut Creek, city officials gathered to discuss a significant residential development proposal that could reshape a quiet neighborhood. The Design Review Commission (DRC) convened on December 18, 2025, to evaluate plans for a new six-lot subdivision on a site currently occupied by a single-family home and accessory structures.

The proposed project aims to demolish the existing residence and construct six two-story homes, one of which will be designated as affordable housing. This initiative aligns with the city’s commitment to increasing housing availability while adhering to the general plan designation of single-family medium residential zoning. The development will also include a private street and a five-foot land dedication along Third Avenue, in accordance with future street setback standards.

As the DRC reviewed the project, they focused on various design components, including the site layout, architecture, landscaping, and the removal of 19 trees—three of which are classified as highly protected in Walnut Creek. The proposal includes new fencing and retaining walls, as well as a density bonus that allows for an increase in the number of homes from the base density of five units to six, thanks to the inclusion of the affordable unit.

The applicant is seeking 13 development standard waivers, which are essential for the feasibility of the housing project. These waivers are intended to address specific standards that could hinder the development's success. The DRC's input will be crucial as the project moves forward to the planning commission for further consideration.

With lots ranging from 2,660 to 4,060 square feet, the subdivision promises to blend into the existing neighborhood, which is predominantly made up of single-family homes. As the city grapples with housing demands, this project represents a step towards meeting those needs while navigating the complexities of urban development and community standards. The outcome of this proposal could set a precedent for future developments in Walnut Creek, balancing growth with the preservation of community character.
