Trails and parks will be a bit more spiffy as 459 new signs are installed through spring 2010.

The signs replace old, out-of-date signs at parks, trail heads, sport fields and in open space areas.

Costs of the program were phased in over several years. In 2009, $16,000 was applied to the signs.

The new signs will have UV coatings to delay sun damage.

“The existing rules signs have outlived their life expectancy, are faded and worn, and don’t contain up-to-date information,” said Tom Hoby, director of parks, recreation and open space. “These signs carry an important public message that helps make parks and trails safe for everyone to enjoy and to protect resources.”

Signs in the parks now were installed in 2000, with a five -year expected life span, said Kari Larese, spokesperson with the Metro District parks department.

The new signs are designed to last a decade.

New rule signs are less wordy and 40 percent smaller, Hoby said.

Each park entrance, playing field, playground and shelter will get new signs. Most will have the rules on them but use images more than text.

Installations started this week.
