Raleigh City Council approved the restrictions in May, citing a recommendation from the Raleigh Fire Department.
The change was made following a fire in March in the Highland Creek Subdivision. Pine straw helped to quickly spread that fire.
In February 2007, a cigarette on pine straw sparked another fire that destroyed 32 townhomes in Pine Knolls Townes off of Capital Boulevard.

Those who are caught violating the ban face a fine of at least 50-dollars.
Chapel Hill was the first municipality in the area to limit pine straw in 2007.
