Mapping party in HMB, Saturday

Downtown Half Moon Bay on Open Street Map. Anyone can edit this map to improve it. Find out how at La Di Da on Saturday.

There will be a mapping party in Half Moon Bay, Saturday, June 11. The group is meeting at La Di Da from about 10am to 2pm. Bring your own GPS or borrow one at the party.  They’ll help you figure out what you can add to the map of Half Moon Bay

I’ve been to one of these in Oakland, and it’s a pretty interesting process.  The goal is to update the information in the Open Street Map, an open-source map of the world

OSM’s incredibly ambitious goal is to build a map database that rivals proprietary maps in its scope. They’re well on their way in many countries, and their data for the US is already very good. They already have pretty detailed information for the Coastside. I’ve updated the map of Montara and some hiking trails myself.

Appreciate the efforts of the folks that showed to fill in the maps. Looking at the posted map, it sure seems past time that SFPUC should open up un guided tour access options for non moto recreationalists on their(our) existing fire roads.
Think of a trail that connects from Purissima Redwoods to Pacifica,with bailout options in HMB,ElG,Montara+Moss Beach….
The Bay Area Ridge Trail is working to make this type of trail a reality….

But until SFPUC lifts it’s overly restricted level of access(Any other SF Bay Area-coastal public owned lands require an appointment to access?) On lands above us here on the coast(no drainage whatsoever towards Crystal Springs) we will have recreational islands of non connected trails to nowhere.(good,but we can do much better)

Here’s an example of what other watershed’s close by offer:

Access to SFPUC lands is definitely a long-term issue.  We don’t have a lot of influence with SFPUC, obviously.

I talked with Leland Yee, who’s running for SF mayor, and this issue is on his radar. He brought it up proactively in the course of a conversation. But this is not an issue with a lot of traction in SF politics.

Thanx Barry,
Thoughts of a rank amateur here:

Bet it’d be ramped up a notch or 2 if all SF residents were required to make an appointment well in advance to recreate on all public open space lands here in SM County…

Wistful wish of a lifelong resident:

To range from Sweeney Ridge x North Peak-Montara Knob-South Peak x Scarper Peak-Skylawn-92-Skyline to Burleigh Murray SP-Purissima Redwoods OSP…

One can dream, eh…

Fact is, existing roads and, in a few short stretches, former roads that are, together, continuous along the ridge could be used for almost all of the Bay Area Ridge Trail north of 92. There would be no new devegetation or runoff beyond what exists now in the watersheds, including those for Pilarcitos Lake and San Andreas Lake. At the northern end, the hookup is with the existing Sweeney Ridge Trail via Whiting Ridge.

This has been looked at and plotted for the BART multiple times by multiple committees for the past twenty plus years. Some of it preceded the formal Ridge Trail. As with the California Coastal Trail, there seems to be little institutional memory or understanding, so nothing moves until there is some political-development agenda that serves special interests and involves spending a pile of money on the project.

In the late 1980s, Chris Church of Montara and I went before the San Mateo County Trails Committee headed by Tony Look to try to get the committee to include the California Coastal Trail in the county trails plan. It wasn’t there yet. As part of our presentation, complete with maps, photos, and the like (this was a little before Powerpoint became ubiquitous), we showed and pushed the concept of three major north-south trail corridors in the county—Bay, Ridge, and Coastal—with numerous interconnecting trails between them. Others, like the Sweeney Ridge Trail Committee of the GGNRA, had laid the groundwork for big parts of the overall scheme. The county trail committee of the time, which was not just a political and/or developer’s tool like many recent committees of the county, was receptive and meshed in many of our suggestions. Chris went on to do quite a bit of volunteer work with the BART.

With the BART starting as a Reagan-era project, it did not have the initial resistance from anti-environmentalists that many open-space and nature recreation projects have. But the original push has waned somewhat as government agencies have taken the initiative from citizen committees. Perhaps a decade ago, a couple of my friends, long distance hikers Bob Cowell and Dinesh Desai, hiked as much of the 400 miles, and then some, of the BART as they could to highlight where the remaining gaps were. (The Chronicle used most of a page for a story on their adventure.) Most of the gaps from that time remain today.

Jim, if you can sneak, you aren’t limited to dreaming.

Being a fella of elderly status….we never sneak, we “range”  (lol)
Thanx for the helpful background info Carl, we keep pushing on the same doors,perhaps someday they’ll start to open a smidge…
