Broadmoor neighborhood. Arroyo Chico entry/exit to S Tucson Blvd. Both streets straddling the arroyo. Weeds, ground vegetation, on top of the arroyo and trees in the arroyo (east side of street underpass) are obstructing visibility to drivers entering exiting the Broadmoor neighborhood. Trees need to be removed, not just cut back, and vegetation on top of arroyo needs to be removed, not just cut back, at least 20 feet back from Tucson Blvd. This has been reported numerous times in the past months and nothing has been done. The inability to see through this vegetation is going to cause and accident. The problem is getting worse as trees grow and weeds, ground vegetation bloom (desert broom) and leaf out. Please address this problem soon.
