If you have exactly one realistic internet option at your house, this is worth watching.

BAM Broadband announced on August 11, 2026 that it is building a new fiber network across four Douglas County communities: the City of Castle Pines, the Town of Castle Rock, The Pinery, and the Cottonwood area that straddles the Town of Parker and unincorporated Douglas County.

The announcement, made from the company's Greenwood Village office, was carried by Broadband Communities Magazine — a trade publication — rather than by local outlets, which is part of why most residents haven't heard about it.

The construction timeline

Per the announcement:

  • Castle Pines — construction beginning the week of August 11
  • Cottonwood — buildout slated to begin later in August
  • Castle Rock and The Pinery — construction starts planned in the next 30 to 60 days, pending permit approvals

That permit caveat is doing real work. "Pending permit approvals" is not a date, and buildout schedules in growing communities slip routinely. Treat the Castle Rock and Pinery timing as a target rather than a promise.

Why this matters here

Fiber competition is the thing that actually moves the needle on price and speed. Large parts of Douglas County — particularly the less dense pockets like The Pinery and the Cottonwood area — have historically had thin provider choice, which is exactly the gap the company is pointing at.

BAM isn't new to the county. The company already has a footprint here, including fixed wireless service and a community partnership with the Highlands Ranch Community Association. This announcement is about laying new fiber, not entering the market cold.

Worth keeping separate: Douglas County is also running its own Highlands Ranch Fiber Improvements project, with fiber optic installation continuing through spring 2027. That's a different effort from this one.

How to check your address

BAM has not released a street-level map for these four communities. The practical option is the company's Colorado site, which has an address lookup for available plans and speeds and a construction progress page showing current zones.
