yeah...i thought you might be the only person from boulder who might consider donating a little time! fortunately i shamed several of my friends into helping and we cleaned up 960 pounds of trash...plus several bags of recycling! we floated it all out on my friends super puma, which does the job very nicely actually.
anyway...yes i'm still here with the forestry division. 55th to 75th is going to be a lot of OSMP and private property. both extremely hard to coordinate with! i think as far as limbing trees it is OSMP policy to leave it go natural...including dangerous situations. Anything in side of city limits is either OSMP, CU, private and some City Parks. anything actually in the water or looming to fall is taken care of by Public Works / Floodways Maintenance...#303-413-7162.
i've never floated from 55th to 75th...i've fished parts of it out by sawhill ponds...so i'm not sure what it looks like. i don't think i'm the man to do all that coordinating. Right now i'm swamped with diseased black walnuts, mountain pine beetle and other urban forestry crap.
but we did have fun wading around in the creek finding various treasures! had some PBR's stashed 2/3 of the way through to keep the morale high. next year i'll be sure to personally invite you.
