So, I'm probably going to get flamed for this, but....
Grand Rapids does have a parking problem. I had customers in from out of state and they went downtown one night to eat. They said the next morning: "Yeah, it looked like a nice downtown. We couldn't find any place to park, though, so we ended up just eating on 28th street instead." So, there you have it, a problem b/c people didn't spend $ in the core. Because we don't have enough spaces? No, but b/c people either aren't willing to pay 6.50 for parking or because they don't know where the ramps and lots are. Would buses help? Doubt it for out-of-towners b/c they probably have the same aversion to mass transit that most GR people seem to have. However, I think trolleys/street cars/light rail would work...it's that whole "tourist" type feel to them that just attracts people, I believe. In my perfect world, there would be lots a few miles out of downtown and trolleys/streetcars/light rail would run from them FOR FREE (parking would cost, but the rail would be free.) This would encourage people to move into the core b/c they could ride for free, people would be able to pay for parking at the same rate since it cost less outside downtown (and the savings would pay for the light rail/streetcars.) Even bussing would see an increase, I bet, because we'd have more public transportation which results in more convenience/flexability. I'd also encourage MUCH more on-street parking....those spaces are more visible and if there are enough, you can just park on the street right in front of the place you are headed. We don't need 2 lanes of traffic on every road in downtown...traffic isn't that bad.
Ok, flame away!
