In my early teens I used to wander the streets, behind buildings and especially along the beach and the back bay. When I was about 15, I sat down and drew this sort of map-aerial view of my old neighborhood. Here's what is what:

1. The lower-left corner is the ocean. The little dots are surfers
at a surf spot then known as "Anderson Street", which was also the
border between Surfside and Sunset Beach. In 1963 the beach was washed
out so the houses to the left (in Surfside) were hanging over the waves
on pilings.
2. The narrow double line is the old Pacific Electric railroad that ran through town then.
3. The four-lane road is the Pacific Coast highway or PCH, complete with cars and a Greyhound SceniCruiser bus.
4.
The two short streets are Anderson Street, center, and 26th Street,
right. I lived on 25th Street, which is just cut off by the airplane
wing. (I don't know why I didn't draw my own house...)
5. Above
the highway were some funky boat harbors and repair yards adjoining
Sunset Bay, the open channels (complete with speedboats) and the salt
marshes. These were already being filled in (at upper right) for
Huntington Harbour, a huge high-end waterfront housing development that
we all hated.
6. The green patches are grassy or marsh areas. The
rest was more or less pavement, bare dirt or sand. Our neigborhood had
no trees, only some lush plantings in yards and in front of some houses.
7.
Houses in Surfside were (and still are) packed together only 3 feet
apart. They were little 1930s cottage then, and most have been replaced
by 32 foot-tall boxes. Most Sunset Beach houses had back yards and I
seemed to know what all of them looked like.
8. The round shape
near the center was the Sunset Beach water tower, which is still there
though is now a private residence, and was featured once on HGTV.
Below
the drawing is a photo I took in 1959 of the tracks looking south from
Anderson Street (or toward the lower right in the drawing). The local
residents parked their cars, hung out wash and burned their trash along
the railroad then. Now it's a long park with paved parking, restrooms,
some grass and trees, and no tracks.

Here is Surfside with the washed-out beach during an imagined storm. I drew this at about the same time as I drew the aerial view.
