The polypropylene surface will look like artificial grass. Its rubberized underlay will lessen the impact of falls.
The synthetic grass is "an excellent choice for high-traffic, heavy-usage areas where low maintenance and water conservation is desired," according to the company's website.
Commissioner Donald Rectenwald, Jr.—a former parks and recreation board member—expressed concern that the synthetic turf will become a standard for all parks in Upper St. Clair.
"I can't imagine that it will be the standard," said Mark Mansfield, assistant township manager.
Mansfield said the municipal park is the "centerpiece of the township" and gets more use than neighborhood parks.
Park renovations are on schedule to finish in the spring of 2013.
The "old" park had a woodchip surface.
