Rezone areas adjacent to commercial streets rather than displacing existing businesses.
Our network of commercial streets are generally the cultural heart of various Vancouver neighbourhoods. Currently, Vancouver is rezoning many commercial areas to accommodate higher density structures. This is a good ideas; however, this progress is slowly eradicating long-time businesses in commercial buildings. This is also eroding Vancouver's commercial property tax revenue.
I believe that (in more cases) the city of Vancouver should be rezoning the single family residences that surround these arteries instead. In many cases the houses are generic 'Vancouver Specials' and lowrise, 1950s style homes that were built to accommodate a vehicle-centric lifestyle. Many people are price out of this type of detached home anyway.
In short: Replace what's not working, not what is.
Concern for the continued viability of existing business is an important issue in Neighbourhood Centre and Corridor planning initiatives. However, rezoning residential properties to allow for commercial uses should be considered on a case-by-case basis (it could work in some areas, but not in others) and should proceed with caution.
