I think Councillor Gondek will put forward a motion to simply allow a built form typology that maintains detached housing and semi-detached. The current lowest density typology in the guidebook allows for 3 storey apartments if I remember. Introducing a newer, lower density typology, that can then be applied to the new local area plans, should calm a lot of the fears.
That said, this typology should have some strong criteria about when and where it applies. Something like at least 2 blocks removed from any collector (transit route), so not fronting these corridors. Nothing adjacent to any commercial or activity center. Really, the center of neighbourhoods like Elbow Park or Britannia, sure. But the homes fronting Elbow Drive (and the alleyway behind those homes) can be the next step up. That would preserve lots of single family homes, but still provide a lot of properties that would allow to be upzoned and redeveloped with intensity.
So, for example:
2.8.h. Lowest intensity, low density residential forms should be supported where the parcel meets one (1) or more of the following criteria:
i. is laneless;
ii. is of a prohibitive parcel shape or size;
iii. is located on a no-through, dead-end or cul-de-sac street;
iv. contains or abuts an escarpment; or,
v. is not located within 600m of a transit stop
Basically, in the medium orange communities (pre 1950s), if one thing on that list is true, then rowhouses aren't allowed. If two things on that list are true, then rowhouses and duplexes aren't allowed; only SFD (with secondary or backyard suites) are allowed.
In the light orange (1950s and 1960s) communities, if one thing on that list is true, then only SFD (with suites) is allowed.
In all cases, on collectors, near transit centers, main streets, activity centers, etc., rowhouses would be allowed.
What you're (reasonably) suggesting as a compromise is actually more density than the guidebook has in it already, to my reading at least.
