A couple of these trails are actually two trails running in close parallel. I would like to survey them in finer detail and map the separate routes.

Also, I don't think bikes are officially allowed in Matoaka Woods, but there are many trails, possibly including this one, that are clearly designed for and used by bikers. There is another trail north of here labeled "Bike Trail" on OSM. How to tag these trails (and as a member of the W&M community, how to advocate for allowing bikes on these trails) is worth further discussion

This looks like a dam, but want a second opinion / might do some research on if it has a name

I don't believe there are stairs here any more. I walked through recently and I believe this surface was level with the parking lot to the north. More surveying needed

This is listed as a community garden on the RVA website, but I can't verify from satellite imagery if it's active.

Is this really Mobil Rd, rather than Mobile Rd? This difference appears to be propagated from TIGER

is there a footway in front of this building (to the north)?

These two buildings look like some kind of culvert...there are likely better tags for them
