A cyclocross event to be held in West Seattle had it's permit by the Parks Department shortly before race day has put a spotlight on not only the environmental impact of the racing itself, but how communication between cycling advocates and the larger community needs to improve.
Read the comments below this post to get a glimpse of not only how members of the same community can have different ideas about how public property should be used, but the varying ways in which both sides get their points across. I'm sure you've seen a similar dynamic elsewhere.
Meanwhile, it would be prudent for race organizers to plan ahead for such trouble by taking the time to produce documents like this one (PDF) that they can present to permitting agencies and the public to show how limited the damage from hosting a CX race would be as well as having in place a post-race restoration plan which might include donations to maintenance funds and having volunteers actively participate in restoration.
As cycling's presence on the public scene continues to increase, we have to be sure that the public at large gets the right impression of who we are and what we do.
