Lower Bear Tributary Arroyo Location Map

Feb. 4, 2020 – AMAFCA and the City of Albuquerque have begun construction on improvements to the Lower Bear Tributary Arroyo. The arroyo extends from Wyoming Blvd. to Spain Road, just north of Arroyo del Oso Park. The arroyo improvements include cleaning out the concrete and trash from the arroyo and adding a maintenance road along the northwest side of the arroyo. The project also includes adding improvements to facilitate the removal of trash and debris from stormwater flows to improve surface water quality in our community.

Over the past couple of months you may have noticed that construction activities in the Lower Bear Arroyo have come to a halt. Unfortunately, due to circumstances beyond the control of the City of Albuquerque or AMAFCA, the Contractor has gone into default and will be unable to finish the project. AMAFCA is working proactively with the surety bond company to retain a new Contractor for this project. Please check back for additional updates related to completion of this project.

There will be no progress or activity at the project site for the next month or so, except for trash cleanup, traffic control, access control, and dust control. Construction is anticipated to start again in late March-early April 2020. In order to address safety and security concerns at the Lower Bear Arroyo Project, AMAFCA has hired a private security company to patrol the project site. Patrols will occur randomly during the day and throughout the night. The patrols started on Monday, September 9, 2019.

Stormwater Quality Information: This project includes construction of a stormwater treatment train. What is a treatment train? As the stormwater runoff moves through this arroyo – from Wyoming Blvd. to Spain Road – it will pass through a series of controls, each designed to selectively remove pollutants from the stormwater. Removing pollutants from the stormwater helps protect the water quality of the Rio Grande and the aquifer.

Car 1 in this treatment train (just downstream of Wyoming Blvd.) focuses on removing large gross pollutants and floatable debris – things like shopping carts, cardboard boxes, and larger food and beverage containers. Car 2 will have two additional debris fence structures. These are designed to capture smaller debris (like plastic bags and water bottles) that makes it through the Car 1 debris screens. The second car also focuses on access into the channel; access is essential, so AMAFCA and the City of Albuquerque crews can safely and effectively remove the trapped debris in both Cars 1 and 2. The first two cars of the treatment train have the “harder”, constructed improvements allowing the heavy maintenance to be focused in this area of the channel while keeping the remainder of the channel more naturalistic.

Check back throughout the construction phase of the project to learn more about each car of the stormwater quality treatment train!
