Vegetation Thinning within
Minnesota Drive Tributary
By Libby Kaiser, Student Intern
Regular routine mowing of portions of the Minnesota Drive Tributary prevents overgrowth
of vegetation around the storm sewer outlets draining to Cherry Creek. Despite the mowing
at the outlets the rest of the stormwater channel had become a tangled mess of invasive
weeds, shrubs, suckers and dead branches.
This gnarled jungle was thinned out in July, 2002, to restore capacity and facilitate
maintenance of Minnesota Drive Tributary. This tributary runs parallel to Cherry Creek
along residential backyards between Monaco and Holly Street in Denver, Colorado.
A private contractor was paid $4,490.00 to cut and remove all woody vegetation within
the channel as well as remove the lower branches of mature trees up to a height of
approximately six feet above the ground. The result is a drainageway free of organic
debris that more effectively prevents flooding near the homes that line its southern bank
while also facilitating access by maintenance crews.
