Perils of CD-1: Arterial Shadowing on West Broadway

West Broadway shadowing
Several months ago, Frances Bula did some scouting about a recently completed five-story rental building on West Broadway. The investigation was prompted by a reader question, since the existing zoning (C-2C) only permits four stories yet this development clearly exceeds that. I may be reading the C-2C zoning bylaw incorrectly, but I think the maximum permissible height is even less. Sure enough, the building is a special CD-1 rezoning under the Rental 100 program. And it highlights a problem that we’re wandering into regarding CD-1 development along east-west arterials.

For those who don’t know the neighbourhood, West Broadway is the quintessential Kitsilano high street, and a popular leisure stroll for residents. This is partly because of broad sidewalks and a quirky mix of Greek markets, restaurants, boutiques, and services. But the other major draw, particularly on the north side, is the sun.
Vancouver Solar Altitude
If Vancouverism emphasizes the view first, it emphasizes the sun second. As a city at high latitude — 49°14′ to be precise — the sun never approaches zenith (90°, or directly overhead). The maximum she climbs is 64.2° on the summer solstice, part of a leisurely loop around the sky that never crosses directly above. In the winter, depressingly, the sun struggles near the southern horizon, failing to reach 30° at solar noon for over three months. (That’s roughly the angle of a fascist salute.) Partly for this reason, the City of Vancouver requires detailed shadow studies of all proposed point towers, usually for different hours of the day on the equinox. In my nonprofessional opinion, it’s worked pretty well. I lived downtown for three years, and never felt uncomfortably shaded. Perhaps it’s all the glass.

Bringing this back to West Broadway, and the sudden winter chill I felt while walking one sunny November afternoon to my favourite Greek bakery at Trutch. The inviting patios at Calhoun’s and Banana Leaf, once sunny spots in winter, now seem consigned to the shadow of the facing building for much of the day. The Banana Leaf patio will probably be in near-perpetual shadow for at least four months of the year — you can’t even see the trademark tropical green façade in my photo. Calhoun’s has lost about half of its outdoor seating over the same period of the year, not to mention a reduction of natural light in the spacious and popular interior. The massing of the building, which could perhaps have been split into two corner towers or incorporated more setbacks like the recent Pinnacle Living on Broadway, is instead a monolithic east-west slab rising directly from retail front to its highest floor. There’s even a cornice, possibly sacrificing a few minutes of spring and autumn sun yet too small to shelter the sidewalk from rain. Above all, the building has cast a shadow on what used to be an pleasantly uninterrupted stroll in the sun, so rare on city streets in colder months. I hate to cast a villan, but CD-1 seems to blame (the bylaw amendment arbitrarily allows a height of 18.5 metres on the site, whereas the previous limit was both lower and required an angled taper of the upper floors).

I predict that north-west arterials will not suffer the same problem, since a midday sun will beam down Cambie or Main even on the shortest days. But the idea of rezoning our east-west arterials with CD-1 low-rise should proceed with caution. I cannot help but note that if the West Broadway building were placed just one block off the arterial, not only would the residents have to suffer less noise, but the problem of shadowing on the commercial sidewalks would nearly vanish. We should make our high streets as inviting as possible, not transform them into canyons where no one wants to linger. Spot rezoning likely does not demand this level of consideration, whereas thoughtful zoning bylaws often do.

As Frances notes, there are now over 600 CD-1 sites around Vancouver. I think it’s time for us to talk about the bigger picture of upzoning in Vancouver, with an understanding that arterial low-rise isn’t necessarily better than scattered tower-and-podium.

  1. If only it were one storey lower, or one block further back, then the sun would still be shining on the north sidewalk.
