Lender said the application didn't mention rehabilitation of the buildings, because the park was initially envisioned assuming the demolition and removal of the two buildings.
The grant could be interpreted to help provide restroom facilities or porticos and gazebos, he said.
But Monroe said the grant appeared to have "wiggle room" for interpretation, and upgrading the buildings might be allowed.
Monroe and Lender said the grant was not stimulus funding, but federal transportation money targeted prior to the recent federal appropriations to jump-start the national economy.
But Lender said the funds would indeed boost the local economy.
"This will employ people, creating a sense that things are happening," he said. "It's good to see tax money being put back to work in our community."
Lender said this grant was the most substantial financial infusion yet for the environmental park project.
"We're very excited," he said. "This is the largest financial commitment we've received to date."
