Mount Baker ‘a planned community’ … there was at least one more of those, on the East side, now called ‘Windermere’. It’s not as exclusive as it once was. (Laws and all.)

Today its website says: “By joining the Windermere Corporation, [sic] you will have exclusive access to our Windermere Park & Beach Club, security patrol line, home check requests, party permits, tennis court reservation and much more.” IIRC the website once even mentioned the price of these, erm, accomodations. - https://www.windermereneighborhoodseattle.org/

And, of course, it’s still next to ‘Laurelhurst’. The names of these places are often, erm, highly literate. Nearby you’ll find Ivanhoe Place, Hawthorne Hills, and Ravenna. ‘Mount Baker’ is not quite so tell-tale, although it’s of course among what realtors would call ‘Seattle’s best neighborhoods’ … "https://seattlemag.com/seattles-best-neighborhoods-mount-baker/
