Drainage Capital Projects
Department Project Title Project Number
Public Works Mackey Creek Flood Study DR2005
Project Description
This project consists of creating new hydrologic and hydraulic models to provide regulatory floodplain mapping for Mackey Creek
from upstream of Shauna Drive to Big Fossil Creek (approximately 2.4 miles). This study would also identify potential future capital
improvement projects to reduce the size of or completely eliminate the floodplain within the study area. The original study for
Mackey Creek was done in 1985 with the City's Master Drainage Plan. New topographic data is available along Mackey Creek and
new floodplain modeling techniques would be used in the study.

Project Justification
The data current effective modeling and mapping for Mackey Creek is based on the City's 1985 Master Drainage Plan. Floodplain
modeling and mapping technology has advanced to be able to better estimate flood risk in areas that have both above and below
ground storm drainage conveyance systems like the upper reaches of Mackey Creek. This study would help to give a better picture
of flood risk to residents and business owners along Mackey Creek and would also provide recommendations for capital
improvement projects to remove/reduce the floodplain throughout the area.

Project Status Update: Project is currently underway and anticipated to be completed during FY21.

Funding Source: Drainage Utility Fund (120).
