They appear to be drilling, but why drill a hole in the street? They spent all day one day last week drilling, and they drilled for several hours yesterday.

I thought about that as well, but I watched for hours and didn't see them keeping the pipes. Perhaps they want samples from a specific depth or depths so they are only keeping small samples that I didn't see.Maybe a soil sample?
How deep did they drill? How long was each pipe section and how many did they use? Did you get a shot of the bit?Perhaps they want samples from a specific depth or depths so they are only keeping small samples that I didn't see.
I didn't see a consistent repetition, and I could not see how high the pipes went when they were pulled out of the ground. It appears that they sometimes pulled the pipe out and then put it back in, and sometimes when they pulled it out they would put another one on the end, and sometimes take one off. Some pipes were maybe 4 or 5 feet long and they were stored in the right-hand area of the machine, while some pipes were longer. I suppose the short pipes could have been drilling bits that they were changing out. Being that so far they have drilled for two days they are either drilling very slowly or they have gone deep.How deep did they drill? How long was each pipe section and how many did they use?

They have three cones there right now. Did they cement the hole before they left, or did they install some kind of cover? Could they have lowered a seismic recorder or maybe a gas or radon detection device?

There is a pedestrian bridge just to the right that was reseated on new concrete supports. It is so recent that it has not opened back up yet. I think the last thing to be done is to pave the approaches. The bridge fell a small amount a few years ago due to the creek that it crosses undercutting a concrete support at one end.Geological mapping of bedrock, or looking for underground aquifers. Is there a bridge near by or Infrastructure being replaced or rehabbed ?
They usually try to find the bedrock before they pour the concrete hahah.. Perhaps something is sagging or they are just completing a area survey, I would be willing to bet its connected to the Bridge rehab.There is a pedestrian bridge just to the right that was reseated on new concrete supports.

It looks like they may do more drilling tonight since I see people and vehicles starting to collect.
Salt water is close by, so perhaps.My guess is environmental testing well. I see them along the coast to test if salt water encroached to the freshwater aquifers. Also see them around waste sites to see if contaminates are migrating away from the source. The bridge repair behind you might be what initiated it like @c hris527 mentioned above.
That would be too easy I looked for workers when getting home from work today but none were around. Currently there's a couple pickup trucks down the street but the workers are tucked inside to stay out of the rain.The best way to find out is to go and ask them.
