An army of workers invaded Martin Luther King Park Thursday afternoon to take out a hidden enemy.

That enemy is trash, a mountain of garbage dumped in the park by careless neighbors.

Forces from the San Antonio Parks and Recreation Department launched an all out assault in an effort to save an amazing natural resource.

Even though it is a public space, the southeast corner of the park is barely used. Crisscrossed only by a few hard to access foot trails, the area is awash in spring flow now.

Water is rushing from springs hidden in small gullies and crevices.

But less than 200 yards away from these naturally beautiful sights, there is a different kind of river flowing.

"It is a flood of trash," Ruben Guerrero, Eastwood Village neighborhood president said.

Guerrero is frustrated with the waste dumped in the park by people who live just across the alley in the 500 and 600 blocks of Upland Drive.

Even though the City of San Antonio offers free curbside pickup of bulky waste and brush four times each year, some of the residents have chosen to dump their trash just outside their back alley, an area that is adjacent to all the vulnerable spring flows.

Guerrero said "It's too easy to just go and dump things down the creekway."

He said the dumping is especially problematic because the trash has to be hauled up a bluff that ranges from thirty to fifty feet.

Thursday, District 2 representative Alan Warrick and his staff worked with the Parks Department to get the mess cleaned up.

Guerrero said he hopes the city's Solid Waste Division will begin an educational campaign as well, to prevent more problems.

"Even doing a door to door campaign, making them aware of options would be helpful," Guerrero said.

Guerrero said just because the trash is hidden in the woods, doesn't mean it should be ignored.

"It's creating a problem. It's costing you money because somebody has to clean it up. Somebody has to take the time out to do it," Guerrero said.

Guerrero said with a $2.6 million dollar park improvement campaign underway, the time is right to make King Park a better place to play.

"Just because it's out of sight doesn't mean it that it doesn't effect the wildlife here. The waterways, because it does.
