>mixed residential/commertial/recreational can be very noisy.

I'd rather live in a somewhat 'noisy' vibrant neighborhood where I can walk to shops or restaurants than an absolutely dead residential cul-de-sac where I have to literally drive miles to the nearest amenity. If the noise bothers you at night, get a sound machine or install triple pane windows.

I understand having industrial separate from everything else, but commercial and residential should always be blended IMHO, and SFH zoning should not exist.

I would kill for reformed zoning standards like they have in Japan.
