Cottonwood Highlands Filing 2A is a subsection of the Cottonwood Highlands residential development located in the Town of Parker, Colorado. The property includes 17.34 acres and will contain 56 single-family lots. Filing 2A is the first phase of the Cottonwood Highlands subdivision. Upon completion, the subdivision will contain around 300 single-family lots.

An existing natural drainage channel running through the property presented unique challenges in terms of legal approval and engineering design.  Meeting the town’s water quality requirements required an innovative approach because the water had to be treated before it could be discharged into the existing channel, but this needed to be done cost-effectively. Though the project is not yet completed, it has thus far been successful.
