City of Centennial issued the following announcement on Oct. 8.
Depending on weather and smoke conditions, expect to see a yellow and blue Robinson R44 helicopter flying throughout Centennial starting next week to complete a three-dimensional mapping project.

- East of I-25, West of Yosemite, South of Arapahoe Road, and North of County Line Road
- Along University Blvd between Arapahoe Road and County Line Road
- Along Smoky Hill Road between Chambers Road and E-470
