No provisions for a bike path connection to the Cochituate Rail Trail? The existing condition with sharrows on a 4-lane road is not exactly adequate.
Wetlands. It is a little hairy getting to the Chop Shops where you could get into the trail from there but it could be cleaned up a bit so that it's only a few steps.
Personally I'd just live at the Avalon/Cloverleaf instead. That's right on the Trail and as a bonus, it's in Natick instead of Framingham. Probably cheaper too despite being $2500+.
Road noise would be an issue.
