It's interesting to read the comments based on that article.
Personally I think she made some good points and I agree with a lot that she said. What I mostly took away from it is that a broader approach should be taken to improve the downtown area, which I've also read here. I agree with this.
I've read many comments on this forum of too many empty lots and a general run-down appearance of the downtown area - I agree with taking the measures to keep developers from creating eyesore empty lots (for years on end in some cases) while waiting for something to be built. I actually like the idea of balancing the tax situation between downtown and the suburban business sites to make it more attractive to maintain downtown sites.
Nothing wrong with doing something to make downtown nicer to look at, more pedestrian friendly, etc. Landscaping, planters, benches, whatever... just make sure they are attractively done and not just poured concrete or some other similarly cheap appearing item.
It seems like a common idea on this forum is that we must make all cities the same... high density, tall buildings, etc. I do question sometimes whether Halifax needs that? It certainly needs some of it, but I think Halifax as a city has a different character and thus needs a different line of thought. Combining heritage and "new" (though "new" doesn't last very long before it becomes hum-drum if no real character and quality is built into the design) is a great idea, but so is designing a new building to fit its surroundings rather than something that sticks out like a sore thumb.
One point I've gotta make... of what significance is the value of the author's home? IMHO, she is giving her opinion that living downtown should not only be available to the well-to-do. It is irrelevant, in my opinion, whether she is well off or not. Just because you can afford to live in a higher-cost dwelling doesn't mean you shouldn't be able to recognize that not everybody can afford to do that. I think details of one's personal life should be kept out of such discussions.
This is all just my 2¢, but I'm not an architect, developer or urban planner... just a man on the street giving his humble opinion. Not trying to offend and no comment is aimed at any one individual, so please don't take it that way.
