Lower Bear Tributary Arroyo Location Map

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 few weeks you may have noticed that construction activities in the Lower Bear Arroyo have been steadily slowing down. Unfortunately, due to circumstances beyond the control of the City of Albuquerque or AMAFCA, and related to the Contractor’s ability to function in the field, construction activities have now come to a momentary halt. We at AMAFCA are working diligently to get construction in the Lower Bear Arroyo started again and look forward to completing this important project as soon as possible.

Week of August 5 – August 9, 2019 Construction Field Reports

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!
