Spent better part of 2 days in San Francisco. While walking around the skyscrapers I couldn't find a single property monument. I did find a few pk nails, 2 crosses sawn into he sw and a couple of municiple bm's, but not a single LS stamped tag or cap. I must have lost my ability to locate corners 'cause I cannot imagine such high value propery to be completely uncontrolled.

Ain't the buildings controlling themselves?

You would not believe what else those san fran ciscans do.
They have lost more than the old landmarks...

Surveying is more than a Job----it is a passion to provide a foundation for future generation, that is beyond reproach.

A lot of SF boundaries are marked by +, L or T cuts on curbs, or crow's feet on building corners. Until fairly recently, the requirement to tag monuments was widely ignored.

I was in S.F. this past weekend for the Municipal Transportation Authority's Heritage Festival. Got to see a lot of old transit and my ride on the Powell/Hyde line took me past the location where they were filming The Antman sequel. I noticed a cross cut in concrete sidewalk and a cast iron monument vault but I didn't shoot any pictures of monuments or try to open the vault lid.

The "L" signifies the parcel that was being surveyed. When the next surveyor comes and surveys the parcel next door they would add the cut to make a "T" to signify both of the parcels had been surveyed in the past. The historical survey archives from the late 1800's and 1900's show this occurring.

I believe the crosses were set later for the property line extensions to the TC.

The vault is on the southeast corner of Vicente and 24th, just down the block from Riverside Seafood Restaurant where I had brunch with my aunt and uncle.

If the building is zero-offset to the property line, might building corner itself might be the property corner. (?) Maybe the PLS should stamp his number in the face of the building by the corner.

I was in NC a few weeks ago and would walk by this one most mornings.
It would be a monument that would last probably till January here, but I guess it's SOP out there to set them:

Made me wonder what dept does these surveys, out west of course I usually deal with the BLM or USFS.
This is at a Federal Courthouse.

btw- i can leave my desk right now and in about 10 minutes walk by about 3 dozen of kent's mags and shiners that have been in place for decades. (texas concrete, like everything else here, apparently works better than everyone else's...)

Their ad would trigger SWMBO.

"Do you know where we survey at"

Fingers on the chalkboard.

I figured U.S. Surveyor was some eastern version of the government surveyors I know. Guess not!!!!
And a Federal Courthouse:(

hahahaha. good thing your SWMBO and my SWMBO aren't acquainted. (drives me nuts too and is a minor source of stress in our house. because, you know- i don't have any quirks that might be irritating to her.)

I am not sure how it works in San Fransisco, but in Seattle the downtown properties are all referenced by centerline monuments. Once you connect the CL's and offset the rights of way, you divide the lots per plat. Since almost all the skyscrapers downtown are zero offset, the centerline monument IS also the property line monument.

I assumed that is how it was done in the downtown area of all major cities.

i will say this: relative to the egg basket of national cheapo firms that do surveys i review on a regular basis, this guy's stuff is reliably pretty good. how that operational model works is beyond me, but he clearly actually has crews on the ground (as evidenced by moe's picture). i'm dead serious when i say that i suspect a number of these firms are doing google earth surveys.
