Hollywood and Irish Detention Pond

The Hollywood and Irish Stormwater Improvement Project was completed in the early 2000’s through Hazard Mitigation Grant Funding awarded to Larimer County. Homes in the area of Hollywood and Irish streets experienced severe flooding and property damage from storms in 1992, 1997 and 1999. The drainage improvements included construction of a regional detention pond, outfall channel and improvements to roadside ditches, which removed over 60 structures from the floodplain.

Sheldon Lake Drainage Improvement

This project consisted of numerous drainage improvements in the area north of Mulberry Street and west of Sheldon Lake. Additional stormwater detention was provided in the City Park Golf Course and in Sheldon Lake. Uncontrolled stormwater spills were eliminated from the New Mercer Ditch and the Larimer County Canal No. 2 between Mulberry Street and the West Vine/Canal Importation basin boundary.

West Prospect Ponds

Completed in 2006, this project included stormwater drainage improvements that eliminated overtopping of detention ponds, which resulted in more than 120 homes being removed from the 100-year floodplain. The overall project limits began at the southwest corner of West Prospect Road and Overland Trail on the City-owned property and extend north to the Minatta/CSU property line west of Overland Trail.

Scenic View and West Orchard Ponds

The 2009 West Orchard and Scenic View pond improvements were initially recommended for the Plum Channel as part of the 2001 Master Plan. Significant flooding occurred in this area within residential neighborhoods and at roadway crossings. Improvements were constructed from Kimball Road to Ponderosa Drive to mitigate flooding. Improvements alleviated unrestricted runoff and overflow spills that caused significant flooding during major storm events.
