FLINT, Mich. (AP) — Flint is building a park at the site of General Motors' former "Chevy in the Hole" complex.

The city on Tuesday announced that leaf and yard compost will be dumped at the site as a cap for the brownfield reclamation project. A massive concrete slab currently sits where a complex of about 20 GM facilities once stood.

Flint says the project also will save the city about $500,000 a year in costs related to hauling away leaf and yard waste and bringing in topsoil for the site.

The city estimates it will take about four years to create the park at the site along the Flint River.
