It took me a day, but I tracked down some information to address concerns about tree roots in boulevard swales.
Chris Johnson writes: On my mounded boulevard, to lower much of it to a swale would mean damaging and exposing the roots of an elm and a pair of linden trees[...]Trees are just too valuable. Making a swale and/or rain garden might not be an option for people with nearby trees. Corrie Zoll writes: My contact at DNR Community Forestry tells me that, if a tree is otherwise healthy, the stress of root damage that would come with removing 2-3 inches of soil should not have any long-term affects. He agrees with you, though, that it's simply not a worthwhile trade-off. His recommendation is to leave the grade as-is for a distance of 10 feet from a mature tree. Of course, this would not apply to a new tree, which would have the opportunity to establish its roots in the lowered boulevard. Corrie Zoll Phillips TEMPORARY REMINDER: 1. Don't feed the troll! Ignore obvious flame-bait. 2. If you don't like what's being discussed here, don't complain - change the subject (Mpls-specific, of course.) ________________________________ Minneapolis Issues Forum - A City-focused Civic Discussion - Mn E-Democracy Post messages to: mailto:[EMAIL PROTECTED] Subscribe, Unsubscribe, Digest, and more: http://e-democracy.org/mpls
