"Authorities said he dug the bike trail into a hillside, hacked down tree limbs and built rock paths through two drainage ditches."
"More pleaded guilty in Marin Superior Court to two misdemeanor counts - willful or negligent destruction or removal of plants and dead wood, and diverting or obstructing the natural flow of a stream."
Thats fair enough i guess, if your going to build trails, DONT hack trees down or F up drains....there are plenty of illegal trails/builders out there, this guy just got unlucky and his 'neglible' actions against trees and the 'natural flow of a stream' are now being accounted for.
