Unique Challenges:
High groundwater conditions combined with nearly flat terrain required unique design solutions for surface grading and drainage conveyance. The high groundwater conditions made it challenging to meet the requirements for stormwater detention and discharge. MacKay and Somps analyzed a variety of storage and pumping scenarios, helping our clients and the City select a preferred solution that was most effective from both construction cost and O&M cost.

Flat terrain necessitated 25 foot deep sewer facilities.

“The project was planned and designed to be built in multiple phases, but when construction started the market was so strong that all phases generally proceeded at the same time. Being able to manage all the clients’ various needs concurrently required a great team effort and a significant amount of coordination. Our success was a very fulfilling professional achievement.”
