"Street pattern" notation on charts?

Hello all!

I'm wondering about a notation I've seen on a couple of VFR sectional
charts. A small area - no bigger than about 3 or 4 miles on a side -
will be outlined with thin black dashed lines, with a note "street
pattern". The note is in the same typeface used for other landmarks
like "golf course", "plant", "hospital", etc. Does it mean something
like "unusual street pattern that is a good visual landmark"? Or
something closer to "this might sort of look like a runway, but it's
not, so don't land on it"? I've looked through the User's Guide at
http://www.naco.faa.gov/index.asp?xm...ine/aero_guide but the
answer didn't jump out at me; is there a better place to look for things
like this?

One example is about 10 miles due east of MKO (Muskogee, Oklahoma). See
http://skyvector.com/perl/code?id=KMKO&scale=2 and look east of MKO and
just north of the small town of Braggs. (For those of you keeping score
at home, this is on the Dallas-Ft. Worth sectional.) Here is a Google
Maps satellite photo of the same area:

That's how I would interpret it. The primary design goal of the sectional
is to serve as an aide to visual navigation. Things get put on the chart
if they're easy to spot from the air and thus serve as good visual
landmarks.

The one that I was familiar with was a case of a a good sized development
that had, for want of a better word, fizzled. Basically, it was a
development started in the sixties with all of the infrastructure, streets
and utilities, in place; but only a small percentage of the homes were
built. The visual effect was that of a small city without the homes.
Effectively, it is a daytime landmark, but won't appear as a lighted area at
night. Therefore, it was charted in the manner you described--rather than
the filled in yellow of a typical town or city.

For any who are curious, the area of that type that I most clearly recall is
called Lehigh Acres and is located in southwest Florida--however, I have
been told that it was finally built out in our recent "land boom." I have
not seem it recently, either from the air or by chart, so I really don't
know the current status(s).

I believe the street patterns are there as land marks, however I have
seen a dragstrip or two on a chart, and I suspect those are there so
as to not be confused with a landing strip.

IIUC, it's where streets were laid out, but no buildings erected (ie, RE
development gone bust).

I turned in to one of those when I was visiting Houston, TX. It was
a whole suburban neighborhood of roads, with mature trees all around,
but no houses at all. It was surreal. Houston also had highway ramps
going nowhere (with matching rusted out cranes). I got the impression
that the money dried up suddenly one day and everyone just walked away.

Yep. There are a lot of these out here in the southwest. I've even seen a
few that were designated as street patterns, then during one of the
inevitable housing booms, were resurrected into actual neighborhoods.

Do you have any lat/lon coordinates?

It sounds like it could be an interesting Google Earth trip.


There's one at N32.554, W111.717. I have heard that there is one of these in this area south of Phoenix
that is an old World War II Japanese interment camp. Not sure if this is it. It doesn't look like it on Google
Earth (named streets and some houses).

That would be the Gila River camp, which is he

It looks abandoned.

The place you're looking at seems to be just another one of those abandoned or
underdeveloped subdivisions that one sees in areas like Phoenix.

Yes, that's the spot I was looking for. Interesting curving pattern of irrigated farm fields to the northwest
makes it easy to spot. However, I don't see that one on the sectional or TAC with the "street pattern"
identification. I guess it's just viewed to be not that clearly visible as a landmark. The historical aspect is
interesting, however.
