I think it is. For some reason, the 5445 Rainnie lot is included in the western height precinct along with the Centennial Pool block, and both pre- and post-bonus heights there are 23 metres (why would they make them the same? are developers not supposed to build public amenities in this area?):

Not sure what's up with the blue and grey corner building.
It will be an uphill battle because of all the terrible buildings, but it would be great to see this neighbourhood seamlessly integrated into the downtown and Gottingen areas. I think it will be about halfway there after the current round of new buildings, and some investment in streetscaping could help a lot. So many of the intersections around there are designed for higher-speed traffic and integration with Cogswell; the benefit to traffic is probably minimal and there's a substantial negative impact on pedestrians. It's common to hear about Cogswell and how it severed Barrington from Gottingen, but actually this area is not much better.
