City Of Good Thunder issued the following announcement on May 19.
Mowing Season is upon us; Please Remember
It is unlawful for any person to deposit, bring or leave debris in any city street including grass clippings, leaves, brush, garbage.
Yard debris, including leaves and other organic plant material like shrubbery trimmings and grass clippings, are a significant source of stormwater pollution.
When you blow your lawn waste into the street it can clog storm drains and cause drainage and flooding issues.
grass clipping in the roads are like ice to motorcyclists and bicyclists. It could cause an accident or seriously hurt someone.
