Here is what I came up with:
I naturally think in HO, so that would be a 36 inch radius going through, maybe a couple straigh sections in the middle. This would make this space about 3' by 3' up to 4' by 4 foot, if it was HO....if you kept it at this space, you would have a very well represented neighborhood, if you shunk it down to an 18" radius, then yo uwould be stuck doing what I would sdo to this space if it were in HO...
The best way for the high tension wire is probably as mentioned, put the pictures in the background, and then, make sure there are no buildings or anything bigger then a Shrubbery (!!!Suspense Chord!!!) under those wires.
The highway is pretty boring and straight, in HO, that might be a two lane road, with the road to your house all being single lane dirt...but you see, I AM from Arizona...but you do have the opportunity for a number of highway over/under passes, as well as a couple railroad under passes...the highway would be an under pass in the lower corner, and an overpass in the upper corner, which accomodates both the highway and the railroad AND the high tension wires, as those wire DO need so much clearence...which you may model as large poles with heavy strands three strand going up the pool on each side...for a total of eight wires due to the light wires on the top and bottom ofg the racks. We have them in Phoenix, though now many are being replaced with the single metal pole type that Don't fall over in monsoon season, anyhow, they are Large!.......The dirt road is a small stone bridge under the railroad at that point.
You neighborhood would feature your house and only the most poignant houses in there...why model the bland?
That is an open meadow, which works well in N...and the road Does have the poingant bend in it...you might focus on that spefiic area, as I am sure it has some extra little details, like road signs...
If this was HO, the main road would be a paved, perhaps only one lane instead of that divided monstrosity...either way, definately paved...the other road would be dirt...and the circle in your neighborhood would be nothing more then a circle around a farmhouse with barns and outshops on the outer circle, or it would be a house with a loop around it, or a volunteer fire fighter station...basically, that would be a lot with a half circle feature to it....ther eamy not even BE the center house, that may be a tree or anything of that manner...
And for another thing, if this was mine,...I might even take out the highway all together and make that a second rail line, going between two elevations, though that would be a little more difficult...it would be a diamond crossing (With a watchtower) in the upper corner...the highway would then be single or double tracks...there might be a station between the existing road and these tracks, serving the people that live in either direction...
My idea on the site...it is a very doable scenery divider, between say a large industry and a city...
