The Island Parkway Project: 400 New Homes Planned for Belmont

A preliminary look at one of the largest new housing proposals Belmont has seen in years

~400

Total Units Proposed

11 Acres

Total Site, 5 Parcels

20 Min Walk

To Belmont Caltrain

Preliminary

Filed May 2026, Not Yet Approved

A significant new housing proposal is moving through Belmont’s planning process, and it’s worth understanding both what’s actually planned and how early-stage the project still is.

What’s Actually Being Proposed

Developer BayWest Development filed preliminary plans in May 2026 for approximately 400 residential units spread across five parcels totaling 11 acres, spanning the Belmont and Redwood City border near Island Parkway, Concourse Place, and Clipper Drive. A full build-out would total roughly 803,400 square feet of housing across 83 structures, with parking for 627 vehicles.

The Unit Mix

Unit Type Approximate Count Location
Multifamily apartments More than half of all units A 7-story building on Parcel 1, Belmont
Townhouse-style apartments 140 units Belmont
Single-family homes 57 homes Belmont
For-sale townhomes 64 units Redwood City (Parcel 5)

A Waterfront Setting With Real History

The site sits along O’Neill Slough and Belmont Slough, close to the Bay Trail, in an area that developers in the 1980s originally called “Island Park” due to the way the two sloughs wrap around and enclose the site. The Redwood City parcel specifically sits near the Bay Trail, adding a genuine waterfront amenity to that portion of the project.

Commute Access

Future residents would sit roughly 20 minutes on foot, or about 5 minutes by bike, from the Belmont Caltrain station, thanks to an existing bike bridge connecting the area to both Caltrain and the Bay Trail.

How Early-Stage This Really Is

As of these preliminary plans, the estimated cost and construction timeline have not yet been shared, and the project still needs to move through Belmont and Redwood City’s full planning and approval processes before any construction begins. The site currently includes vacant land, three vacant commercial buildings, and a parking structure, all of which would need to be demolished first. Notably, an earlier, separate proposal for the same site as a large life sciences office campus, from BioMed Realty, has been formally paused, suggesting this residential direction is now the more active path forward.

Key Takeaway

The Island Parkway project could add roughly 400 new homes near the Belmont and Redwood City border, a genuinely significant addition to local housing supply, but it remains in a preliminary planning stage with no confirmed timeline yet.
