Bigler Avenue, the Clarendon Heights Avenue That Isn’t

I have a stunning single family home at 40 Belgrave Avenue for sale. The Avenue is now part of the Cole Valley neighborhood. The homes on Belgrave Avenue did not exist until developed as part of the Clarendon Heights neighborhood on the upper slopes of Twin Peaks.

Cole Valley & Clarendon Heights

If you’ve ever wondered why Cole Street dead-ends at the base of a rocky cliff and Stanyan and Shrader dead-end at a two-block street that goes from a hike/bike trailhead at Sutro Forest to a hike/climb staircase at the bottom of Tank Hill, here’s the best answer I’ve been able to find:

  • The southernmost street of Cole Valley makes sense as the northernmost street of Clarendon Heights.
  • The Clarendon Heights east/west streets are: Belgrave Avenue, Clarendon Avenue, Mountain Spring Avenue, St. Germain Avenue, and Palo Alto Avenue (from north to south).
  • Glenbrook Avenue runs in a northeast/southwest diagonal across the neighborhood. Clarendon Heights street names are all Avenues. That’s your tip-off that Carmel Street, the next east/west street to the north, wasn’t developed as part of Clarendon Heights.

The Undeveloped Bigler Avenue

Bigler Avenue was designed to be a north/south street between the homes at 25 Belgrave Avenue and 19 Belgrave Avenue. Bigler Avenue would have formed a four-way intersection with Twin Peaks Blvd. and Clarendon Avenue.

  • For whatever reason, Bigler Avenue was never built into an avenue or a street. The land does not currently have a tax ID or APN that we can find, and while we assume it is now owned and the responsibility of the city, we don’t know and haven’t been able to track it down yet. Do you know? Any insight into the undevelopment of Bigler Avenue is much appreciated!
  • Bigler Avenue currently is an undeveloped ‘greenway’ with an unmaintained and steep/rocky/uneven dirt foot path that connects Belgrave Avenue to Clarendon Avenue at Twin Peaks Blvd.
  • Isn’t it Ironic? Clarendon Heights was developed when the car was king and no self-respecting upper-class American walked on foot or used public transit. Of all the SF neighborhoods to not develop an avenue for cars… and then have that undeveloped avenue become exclusively for pedestrians?

Belgrave Avenue is the new Broadway, the avenue with the most expensive home ($25,000,000) in the area, and with multiple homes that are now valued at over $10,000,000.

Which gives someone an opportunity to create their own $10,000,000+ view home at 40 Belgrave atop Cole Valley. Or at the base of Clarendon Heights. No matter how you classify it, the views are stunning and the Avenue is special, even for San Francisco.
