"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 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.

There used to be one of these in Kansas City, Missouri, as well. In
this case, though, the area _used_ to be full of houses. The houses
were bought and razed some time in the late 1960s or early 1970s,
nominally for the purpose of building a highway, but allegedly for the
purpose of "cleaning up a bad part of town". There were trees, streets,
street signs, and even street lights, but no houses. About 25 years
later, they finally built the highway - US 71. The place I remember was
on the north side of 63rd St.

I've seen some of these street patterns in the desert where there's no
infrastructure like roads laid, it just looks like the dirt has been
scraped out into a street pattern (like someone drawing lines in the
sand). They are also in the middle of nowhere. I guess someone wanted to
practise using a bulldozer.

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).

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.
