Ah, I have answers to your questions.

The drawing is oriented with north pointing to the upper left. The big tree-lined boulevard in the middle of the drawing is 527. The stadium at top left is also roughly at the top left of the Google maps picture. The street east of 527 is 101st. I cropped the map to include as far as 104th, but the drawing only goes most of the way to 102nd. 98th is visible to the west of 527. The road on the far side of the stadium where 527 bends is 188th.

One reason it's hard to make the correspondence is that 522 is planned to realign southward straightening out the bend at downtown. (It will, unfortunately, run almost exactly through where Tandoori Fire is now.) Main and 185th will both be continued on the western side of 527. The other reason is that the west side of 527 will be completely redeveloped. The stadium is one of the only familiar features to be retained, and in the drawing it's improved.

As for why Bothell sprawls all over two counties, it comes down to the Growth Management Act. County government encouraged unrestrained development, so the GMA called for incorporation of all urban and suburban areas into new or existing "cities" that could then provide services and regulations. When the GMA went into effect in the late 80s and early 90s, Bothell was the only legal "city" in the area. Kenmore and Woodinville were unicorporated. The closest other cities (off the top of my head; it's possible the first two were not incorporated) were Lake Forest Park to the west, Mill Creek to the north, Kirkland to the south, and Duvall to the east. Bothell planned to take pretty much everything it could. This eventually led to the incorporation of places like Kenmore and Woodinville and Brier that did not want to become part of a behemoth Bothell. All cities in the area continue to have planned annexation areas for the few bits of unincorporated "urban" King and Snohomish County that still remain.
