Design Review Commission Meeting on Mount Diablo Mixed-Use Development - September 17, 2025

The Design Review Commission convened to review and provide feedback on the proposed Mount Diablo mixed-use development at 2094 Mount Diablo Boulevard. The project, comprising 74 residential units with a daycare center and commercial space, was presented by staff and the applicant. Commissioners engaged in discussions focused on design, safety, and logistical concerns, offering recommendations for the Planning Commission's subsequent review.

Public Comments & Testimony

  • A neighboring property owner expressed concerns about public safety due to limited visibility in the long driveway, increased traffic on shared easements, and potential drainage issues. They stated they were not fundamentally opposed to the project but urged careful consideration of these impacts.
  • Charles Krelling, former Design Review Commissioner and current Transportation Commissioner, expressed support for the project as a well-designed development that helps meet housing goals in a suitable location. However, he raised concerns that the provided parking (84 stalls) might be insufficient for the expected 120-150 cars, leading to traffic congestion and parking shortages in the area.

Discussion Items

  • Staff presentation outlined the project details: a 74-unit mixed-use development with eight very low-income units, qualifying for density bonus waivers and concessions under state law. The project is subject to the Housing Accountability Act (SB 330), limiting the city's review to health and safety impacts.
  • Applicant presentation highlighted design features such as contemporary architecture, a mechanical parking system, private balconies, and a rooftop amenity deck. The applicant emphasized the inclusion of a daycare center and on-site parking despite no requirement due to proximity to BART.
  • Commissioner deliberations focused on several key issues:
    • Fire safety: Commissioners questioned fire apparatus access, turnaround space, and compliance with fire codes, noting the need for wider easements and approved alternative methods.
    • Stormwater management: Clarification was sought on drainage plans, with the applicant confirming a detention basin in the rear of the site.
    • Pedestrian safety: Concerns were raised about lighting, surveillance, and sight triangles at the Mount Diablo Boulevard intersection to ensure safety for children and pedestrians.
    • Aesthetic concerns: Some commissioners suggested adding more material variety to the facade to enhance design, though this was not enforced.

Key Outcomes

  • No formal vote was taken; the commission provided feedback to be forwarded to the Planning Commission for final design review and permit considerations.
  • Recommendations included:
    • Sharing the drainage plan with the neighboring property owner to address water management concerns.
    • Enhancing lighting and surveillance in the driveway area to improve public safety.
    • Working closely with the fire department to ensure adequate fire apparatus access and turnaround space.
    • Ensuring an adequate sight triangle at the Mount Diablo Boulevard intersection for pedestrian safety.
  • Upcoming event: A special joint meeting with the Planning Commission is scheduled for September 25, 2025, for a CEQA primer presentation by the city attorney's office.

The commission cannot act on items raised during public communications, but may respond briefly to statements made or questions posed. Do we have any requests for public communications outside of the public hearing? Okay, so we're moving on. So before we go to the public hearing, has anybody had any ex parte communications regarding this project? No, no. Excellent. So open the public hearing. And I understand we have one item tonight, and it's the Mount Tablo mixed use development. And I understand staff has a presentation. So go ahead when you're ready. Okay. Good evening, Commissioners. Simmer Gill, senior planner with the city. We are here tonight to um receive a design review commission feedback on the proposed Mount Diablo Mixed Use 74 unit residential development that will be located at 2094 Mount Diablo Boulevard. Uh to answer any questions that you may have after the presentation, as am I available for any questions. And also identified as an opportunity housing site in the uh housing element inventory uh table. The site is a little over 24,000 square feet in size, and there is an existing uh commercial building on site. The surrounding area consists of a mix of commercial and retail uses, and there are residential uses to the north of the site. Um, and I have identified with the star is the existing building that will be demolished for proposed construction. So moving into the project request, um the existing building will be demolished to construct the seven-story 74 unit uh mixed use development. Uh there is a 3,000 square foot ground floor commercial space, and uh the project also includes a 861 square foot daycare center that's located towards the back of the site, uh, closer to the north end of the site. And uh the project consists of a mix of studios, one bedroom, and two bedroom units. Uh sizes range from 591 square feet to approximately 1,500 square feet. Uh new ground floor and rooftop uh landscaping is proposed, and we'll go into more detail as we go into the landscape plans. Eight surface parking stalls and eighty um eighty of those stalls are provided in a mechanical parking system. The project is also requesting a drip line encroachment permit as there will be work near the drip line of neighboring trees along the west property line. So this project is also providing eight very low-income units as part of the project, therefore being processed under the state density bonus law, which does allow waivers and concessions to city's development standards in order to develop this project. And this project is also being reviewed under the Housing Accountability Act, also known as SB 330. So tonight, design review commission will essentially be providing input, their feedback on the site layout, the building design, the landscaping, and then provide a recommendation to the planning commission who would be the considering body for the design review of the building, the conditional use permit for the daycare, the tree drip line encroachment permit, as well as consider the concessions and waivers that are being utilized under density bonus. Again, as mentioned earlier, this project is being processed under housing accountability act, which really limits the city's this the city's review to really if the project is providing multiple housing units as well as consistent with the city's objective standards as well as the city's design standards. The project cannot be denied and the density cannot be lowered unless the city staff or the commission makes findings that these project will result in any health or safety impacts. And here is some information on the density of the project. It is zoned mixed use commercial, has a general plan designation of mixed use commercial, which allows 88 dwelling units per acre, resulting in a base density of 49 units. The applicant providing eight very low-income units then allows them to have a 50% increase in density, which results in 25 bonus units with a total of 74 units allowed for this project. And the applicant is building 74 unit project with requesting seven waivers as well as two concessions.
