Depends what you consider peripheral. The places within a couple hours big enough to notice as you drive through are basically Lions Bay/Squamish going north, Maple Ridge/Mission on the 7, and Abbotsford/Chillwack/Hope on highway 1 out the Valley. Chilliwack and Hope might be cut off, though I think it's possible to get there via minor roads/unusual routes. Abbotsford is partly flooded, but areas that aren't should be accessible. Lions Bay/Squamish and Maple Ridge/Mission are fine, as far as I know. So if a 1-2 hour drive is the limit, then parts of Abbotsford/Chilliwack/Hope are pretty miserable right now, but it should be fairly localised. On the other hand, you can argue that most of Southern BC is "peripheral" to Vancouver, despite parts being 4-5 or more hours away. Those parts will have more issues, since you start getting into places where the only connections are (were) the highways that flooded and washed out.
