Four new developments under consideration by City staff are of special interest to D1 residents. I will share updates in future D1 Digests, but please sign up at the project websites for the latest information.

Hillsdale Reimagined Project
The Hillsdale Reimagined project (discussed in my February D1 Digest) continues to be reviewed by staff and a Neighborhood Zoom Meeting was held on April 29. This is a multi-decade project, but your input now is important to ensure the project meets community needs. Read the growing Frequently Asked Questions (FAQ) list and sign up for future communications at https://hillsdalereimagined.com/.

1 East 4th Avenue Project
The City has received a preliminary application for a new 14-story multi-use building at 1 E. 4th Avenue on the corner of El Camino Real. The project proposes:
Approximately 12,000 square feet of ground floor retail/restaurant space,
Approximately 108,000 square feet of office space (5 stories)
236 for-rent units, including a total of 36 BMR units (15%) based on the County’s Average Median Income (AMI):
18 units (devoted to the very-low income households
18 units (devoted to the moderate income households
171 below-grade parking spaces
On-site amenities including a movie theatre, golf simulator, private lounge, spa, and gym
This is only a preliminary application and there will be several opportunities for community input. But now is the best time for your opinions to influence everything from the design of the building to how it impacts traffic, parking and the well-being of Downtown San Mateo.
Please plan to attend a neighborhood Zoom meeting, hosted by the developer, Mecah Ventures, on Monday, May 12 at 6pm. The Zoom info follows, and I would be happy to speak with anyone about this project.
A virtual neighborhood meeting will be held on Monday, May 12, 2025 at 6 pm online at: https://arctecinc.zoom.us/j/82607044041

Project Update
The current formal Planning Application (PA-2025-038) was submitted on May 1, 2025 and is currently under review.
This formal Planning Application follows submittal of an SB330 Preliminary Application (PA-2025-006) which was deemed complete as of April 9, 2025. The Housing Crisis Act (SB30) (Government Code Section 65941.1) is a state law allowing the project to secure development standards, fees, and regulations as they apply at the time of submission with the submittal of all required documents as outlined in the City’s SB330 checklist. More information on SB330 can be found in the Housing and Community Development (HCD) website.
I will be meeting with the developer and will keep you updated.
