When powers that be won't listen:

1. Have a drone survey to do: not a big deal, the drone people hired us to lay out around?ÿ70 targets over a site, this is a campus and I figure it will go smooth. Had it set up for a couple of weeks ago on a Sunday while there is nothing going on. The powers that be for the campus decided it was too early and want to wait a couple of months because there is something they want seen in the photos. Meanwhile the trees are leafing out and it's going to for sure degrade the survey in the areas that were open when we wanted to do it......

2. The city passed an ordinance some time ago that declared that vacated streets go to the lots and to the center of the street. Well that is true most of the time but when the lots don't have possibility of reverter as stated in state statutes and state supreme rulings then they don't get to the center or sometimes any of the street. So no matter what you tell the city they don't want to hear it......

3. The GIS department seems to be in charge, sent a vacation document signed by the commission and clerk for a Tract in a subdivision and can't file it without a description, so I sent the description that is attached to the vacation documents: Tract 11 of xxxx subdivision. Well that's not a "valid" description, they need a "real" description,,,,,,,,finally I wrote one describing the vacated Tract's record bearings and distances......Made them all happy.

Surveying is a weird profession.

The City can't convey property owned by others by Ordinance.

At least the city quit writing deeds for vacated property, now I think I have the county stopped. Who knows what will happen when the next batch gets elected.

He likes his control, the next area has about 100 that we will do for him. I don't do it, never had a good reason to buy one, but these people seem to get good answers and do a good job, I think the first site is about 60 acres.

Speaking pretty generally, thats way too many.?ÿ Granted I dont know how large the site is, or if its multiple sites etc, but I typically fly 150 acres with 6 GCP's and typically get a verified accuracy of 0.1' @ 400' (would be tighter if I flew lower).?ÿ Introducing a lot of extra GCP's has only brought the accuracy down in my experience.

How do you know the city doesn't own it? Who has the burden of proof?

I'm working on a survey, where the deed says, "except the south 20' for road", so does the neighbors; creating 110' of "road", 20' wide. This is access to a small parcel, that was never developed and the "road" never built. The survey is to consolidate 7 parcels and develop a commercial site (restaurant). the client wants to own the road, at least the part that adjoins his property.

Does the city own this "road"? If not, who does?

TIA

I'm not an expert in these drone flights, I do know these guys set a lot of control, some of their clients want a lot of checks on the photo's, I think they have been burned by other flights.

We are?ÿthe grunts for these projects. And more than happy to do them, great guys to work with. ??ÿ

The city has a fee simple determinable ownership in a street created by statutory dedication. The abutters hold a possibility of reverter and the dedicator retains the minerals under the street.

If owned in fee the city can sell a street, but for statutory dedicated streets all they can do is vacate, the ownership of the street is already held by the?ÿlandowners with reversionary rights.

For your street it may be a private driveway with no public ownership, a different animal. If it is a dedicated street the state laws and court rulings would control.

I'm sorry, but how can additional control possibly degrade the accuracy?

The City is purporting to convey a fee underlying an abandoned street to an abutter.

For example, if the Street was dedicated out of one owner (so-called marginal street) then it reverts back to whence it came, the City's ordinance is ineffective to convey half the street to the other abutter that never had any interest in that half of the street.
