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. The construction is currently scheduled to be complete in early July 2019.

Week of June 10 – June 15, 2019 – Construction Update: This week, the contractor will pour the last concrete section of slab and walls in Car 1 on Thursday (June 13, 2019). They will also begin waterproofing and backfilling the constructed walls in Car 1. Grading work in Car 2 will continue throughout this week. Construction materials will continue to be hauled to and from the project site with large trucks.

The contractors current schedule requires that they begin working on Saturdays in order to complete the project by mid-August. We need the community’s help to accommodate the Saturday work schedule to ensure this project can be completed before our typical monsoon rain storms. It you have any suggestions on how to make the construction process smoother for the community, AMAFCA welcomes your suggestions and would be happy to discuss this with you. Please contact Patrick Chavez at AMAFCA with any suggestions or concerns, phone: 884-2215, email: pchavez@amafca.org.

Week of June 10 – June 14, 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!
