Police are evacuating some residents of the Plum Creek neighborhood for a second time in less than a month.

Town officials say they're taking the final step to clean up a condemned home on West Prestwick Way after an explosives scare on Halloween.

A contractor has been working for about three weeks to remove the chemical compounds found in the home.

Now, they say eight homes need to be evacuated again to finish the job ahead of Thanksgiving.

Castle Rock Fire and Rescue will start evacuations at about 9:45 a.m. Wednesday morning. Those evacuations are expected to last through the afternoon.

Officials had originally evacuated more than 30 homes when the explosives were discovered. Authorities detonated those devices at the Plum Creek golf course behind the neighborhood.

Crews are nearly done with the work, but say some of the leftover chemicals could be explosive.

CRFD will be working alongside Douglas County Sheriff’s Bomb unit to finish the last portion of clean up.

Two 16-year-old teens are being charged for the incident. Because they are under 18, neither has been identified.
