Did you ever get an answer on this?
I am fairly certain that the structure is a round gazebo (aka: a summerhouse). I have attached a Sanborn map from 1892 where an identical the structure is labeled as such. The 1 X denotes that it's a single story structure with a shingle roof. I suspect that the dashed line of the structure outline denotes that it's an open structure as a gazebo would likely be.
Sounds de minimis to me (assuming you feel the Phase II was adequate).
The concept of dry cleaning was discovered in late 90s its not new and I believe its so far the best way to get the cloth or rug clean. I've been following the commercial carpet cleaning Denver blog of ECO clean cares and has been successful in cleaning our workplace carpets with petroleum.
Interesting. I looked at all my sanborn legends and do not see anything that is a circle with dashed lines. Its pretty large, so maybe a cistern? Do you have any more sanborns for the area? It's really hard to tell. I wouldn't guess what it is but state an unknown marking in your report, unless previous maps show something else. Are there any objects matching up to it on an aerial?
I wasn't able to determine exactly what it is. However, you may have better luck comparing it to the attached sanborn legend.
Here's a zoomed out screen shot. The red arrow points to the marking in question. It's in an open area on a residential property.
Can you post a pic that is a little further out? It looks like a hydrant or something, but most hydrants are not dashed lines. What type of property is it on? In a building?
Fuel Ho. = fuel house, the top of the o is not legible.
Does anyone have good language for this? I have recently encountered the exact same scenario.
Getting paid for a Phase I contingent on closing (read: not finding any RECs) sounds like a conflict to me. I wouldn't go there.
It could only be a historical REC if it has been addressed and adequately cleaned up.
The one's that I hate are the projects where you find RECs and it busts the deal. Now no closing occurs and you getting paid was contingent upon that happening.
