Town of Farmington GIS - ArcGIS Server Parcel Application
This is the best map I can find showing 4 Jefferson Crossing and all of the Farmington Foregroup properties. I don't have a list of the property addresses, but 80 Mountain Spring is also visible. You can zoom in and out, but the best thing about this map is if you go to the upper right hand corner under "Map Layers" and click on "2016 Color Ariel" you get a wonderful winter non-vegetated view.
Notice the Jeff Xing back yard and it's VERY close proximity to ~vast~ wilderness? That, my friends, is the approx 3k acres of the West Hartford Reservoir. It is open to public hiking, and the Metacomet Trail also passes close to his house. If you click on "Trails" under "Map Layers" I believe it will place a green line for the Metacomet. The reservoir property is not included for the most part on this map because it's mostly not in Farmington.
View attachment 191934 *Here is a map for the West Hartford Reservoir. I have put a red dot on the location of the 4 Jefferson Crossing property, next to the path that forms a sideways "U" right above the words Kilkenny Rock. Below I will zoom in on the area in another pic from the Farmington GIS link.
View attachment 191935 *I put another red dot at the Jeff Xing address. The green line here is the powerline, the red line is the U-shaped path, and the blue line is Metacomet Trail.
