Project Background

This project will have the dual benefit of replacing failing corrugated metal pipe (CMP) storm sewer, and address street and structure flooding in the vicinity of Briarwood subdivision and Tomahawk Elementary School, northwest of 139th Street and Brougham Drive.

A Preliminary Engineering Study (PES) was conducted in 2018 and identified six (6) homes that flood during the 100-year (1% chance) flood event, along with street flooding at locations on Brougham Drive, Sycamore Street, and Edinburgh Street. The Engineer of Record’s refined models reveal very similar results as the PES. To address flooding, this project will include replacing failing CMP along the main trunkline with larger concrete pipe, adding additional stormwater inlets, and upsizing existing inlets in the project area.

Project Updates

A recent rainfall event on July 16, 2025 caused property damage throughout the project area. City’s Engineer of Record will be analyzing this storm to determine what magnitude of rainfall event occurred and will issue a statement that will be posted on this project page in the next couple of weeks.
