This map (https://maps.nicholsonroad.com/zones/) from another thread (https://news.ycombinator.com/item?id=30960632), I think illustrates the problem.

If I understand "the pennisula" correctly, you are referring to something like 1/10th of the city proper (not the greater area, just the city of Vanc.). It is mostly zoned appropriately; outside of that it's a mess.

Everything in grey and yellow is part of the problem mentioned above.
