We just went through this exact thing down Patterson from you. The Parks Dept. are never going to grind it. They flat told me so. I got several quotes, and mine was about the same size as yours. I ended up going with someone Kevy Duty had gotten a quote from and forgot their name, but they were by far the cheapest at $175 for mine and $175 for my neighbor's. Everyone else wanted around $300 because of the proximity to the road. I have never run a stump grinder, but I think that being that close to the sidewalk and road make's it tough for someone that does not know what they are doing.
