There is debris that falls from the trees on the bike lane, WB Olympic Blvd between Pleasant Hill Rd and Reliez Station Rd in Lafayette. Its mostly leaves, twigs, branches, acorns, and pine cones. Bicyclists have to get out of the bike lane and into the lane of auto traffic to get around it. They keep the auto lanes clear but why aren't they keeping the bike lanes clear? Please make the bike lanes useable by keeping them clear.
