Monte Carlo Trails Park Concept Plan Phase One


The Monte Carlo Flood Control Basin project is located in northeast Nogales, south of E. Baffer Dr, east of N. Via Madonna and west of the Mountain Pointe Apartments in the Monte Carlo neighborhood. The property is owned by the City of Nogales and surrounded by neighborhoods and private property. The project was constructed in response to recurring fooding to along Monte Carlo Wash in the early 2000’s.

The Property’s close proximity to surrounding neighborhoods and relatively natural condition make it well suited for park, trails and recreation development.

Project Partners

0S3 Movement is a non profit organization whose mission is to enhance wellness by promoting bicycling as a means to good mental and physical health by producing bicycling, cultural and educational events. The organization identified the lack of nearby mountain bicycling trails as an impediment to local participation in bicycling, especially among youth and families.

The City of Nogales is the landowner of the Monte Carlo Flood Control property. Representatives from the City Manager’s office as well as the Planning and Zoning, Parks and Recreation and Engineering divisions will be involved in this project.

The National Park Service (NPS) Rivers, Trails and Conservation Assistance program offers help to community groups, nonprofits, tribes, and state and local governments who want to conserve and improve access to nature through the development of trails and parks. NPS has been providing limited support to 0S3 Movement since late 2016.
