Thorpe Hillside Drainage Improvements/Flood Control (Summer 2012)

A series of rock check dams and two bio-retention/rain garden basins were installed in the summer of 2011 at Thorpe Park near the Adult Recreation Center and West Cherry Avenue. This project was funded through the City of Flagstaff Stormwater Utility Fee as part of the Stormwater Drainage Improvement Program.

Goals of the Project included:
  • Provide for storage and retention of stormwater from Thorpe Park to mitigate historic flooding in downtown neighborhoods and to address erosion challenges, as well as to improve water quality;
  • Utilize passive stormwater to create native plant landscapes and beautify existing City owned public spaces.
