LONGMONT - In an effort to green its redevelopment of the Twin Peaks Mall, NewMark Merrill Mountain States announced this week plans for recycling and reusing materials from the "deconstruction" of the old shopping center.

NewMark Merrill's regional manager Luke McFetridge said demolition would begin in late spring or early summer. But the deconstruction process will happen in multiple stages leading up to that.

Fort Collins-based NewMark Merrill is planning an $85 million redevelopment of the mall, dubbed Village at the Peaks, that will include a new Whole Foods grocery store, Sam's Club and Regal Cinema movie theater. The project is slated for completion in 2015.

NewMark has begun the first phase of deconstruction, which includes removing unattached or detachable things like tables and chairs. Habitat for Humanity and ReSource have already begun removing and reselling such items.

The second phase includes collecting larger and harder-to-remove items like display cases, light fixtures, store gates, HVAC units and ceiling tiles. Those items will be sold at an auction, though no date has been determined, which will take place at the mall. Ten percent of proceeds from the auction will be donated to the I Have a Dream Foundation of Boulder County.

McFetridge said some things that are left over after the auction will also be offered to Habitat for Humanity and ReSource before being recycled if possible.

"We've really focused on reuse," McFetridge said. "For us, it's more important to see these items make it back into the community."

A third phase of deconstruction will include grinding up construction materials like concrete, asphalt, metal and bricks from the old building and parking lot for use onsite as fill and road base for the new shopping center.

Any leftover steel will be removed and recycled, McFetridge said. Much of the interior finish like drywall, he said, is not typically reusable or recyclable and likely would head to the landfill.

"But we're confident we'll divert a significant portion from the landfill," McFetridge said.

The Twin Peaks Mall is not the first deconstruction project for NewMark. The company focused on deconstruction of a former Nate's restaurant at its Fort Collins Marketplace Shopping Center through the city's ClimateWise program.

Most of the stores at the Twin Peaks Mall have closed, though a few, including the movie theater, remain open.

Dillard's closed in February after a long condemnation battle between Longmont and the retail chain ended in a $5.5 million settlement that allowed NewMark to take ownership of the store. NewMark had purchased the rest of the mall property in 2012 for $8.5 million. But Dillard's held veto power over any redevelopment plans.
