The 95% number is only for monthly permit parking, so that number is deceiving and rarely explained in the news articles I've seen. I walked through several of the parking structures yesterday afternoon which indicated large parking availability on the GR Parking app, and (without counting every single space) there is a lot of parking available.
I'm talking about a third-party study or research. The Chamber is basing its recommendations off of a survey of its members and meetings with them. While public outreach and involvement is important, it does not tell the whole story regarding existing conditions, as opinion is not always reality. I'm not a politician; public opinion alone doesn't do it for me. The Chamber is a fantastic organization, but it has an agenda. They offer solutions, which is great, and I think that should be part of the overall discussion. I am a huge fan of remote parking (one of the Chamber's recommendations) as I've used it in other cities, including DC, Chicago, and in Munich, Germany.
