The Laneway notices provide a really good example (IMHO) of what zoning signs should look like. Provide some detail on the sign itself - including a diagram, if applicable. Make it visually appealing. Provide contact info for more information.
I'm certain these cost more than the existing zoning signs (due in part to the fact the existing signs are re-usable), but the existing signs provide the bare minimum amount of information.... no more, no less. Even for people who are interested/affected, the current signs offer very little info, and make accessing more info cumbersome.
Other cities have used more visually appealing/informative zoning signs for a number of years. It's time for Regina to step up its game.
