RRP Flow of Traffic

 

Brantner Gulch Improvements

The Brantner Gulch Project is a collaborative partnership with the Mile High Flood District to design and construct stream restoration and flood control improvements in the Riverdale Regional Park in order to address the Brantner Gulch capacity issues and reduce flood risk. The stormwater flows from this highly developed watershed cause damage to infrastructure and send overflows into nearby storage lakes, which threatens the natural resources, wildlife, and surrounding residents and businesses. This project will construct a new gulch to protect people and property against flooding, enhance the stormwater quality within the stream, and will change the floodplain map effectively taking the fairgrounds out of the floodplain. It will also provide an opportunity to beautify the park further, naturalize the area, and create more spaces for enjoying nature. These improvements will establish a foundation for future progress of the park, create a secondary egress for emergency vehicles, expand Park Boulevard for more efficient traffic flows, and allow the Park and its facilities to be used for emergency sheltering.

It is slated to begin in November 2024 and continue in phases to accommodate operations and events with an anticipated completion in mid-2026.

Site Infrastructure and Utilities

The Riverdale Regional Park is in need of infrastructure improvements to maintain existing facilities and usage and to prepare for future expansion and the increase in visitor usage. The project will entail upgraded electrical, sanitary and storm sewer, domestic, fire, and raw water, and fiber for internet service. It will also include site work, improved drainage, roadways, parking lots, pedestrian paving, landscaping, and lighting.

Midway Relocation and Barns

The new Midway will be large enough for the entire current Fair layout, plus expansion space. It will provide better access, pedestrian safety, and enhanced experiences. It will create a drop-off area in close proximity to events with a circular two-lane drive and direct bus access.

The new barns will create an “Ag land” atmosphere and support the Grand Stands, Outdoor Covered Arena, Fair, and other agricultural and livestock events within the Park.

Outdoor Covered Arena

This will be a covered, open air arena with a dirt floor to support equestrian, livestock, and community groups such as 4H.
