October 19, 2020 – AMAFCA and the City of Albuquerque are excited to again begin and complete construction on the Water Quality improvements to the Lower Bear Tributary Arroyo. On July 13, 2020, construction re-started on the arroyo that extends from Wyoming Blvd. to Spain Road, just north of Arroyo del Oso Park. See the location figure for additional location information.
Maintenance of the water quality facility will include cleaning out the accumulated vegetation and construction materials debris from the arroyo; and adding a permanent earthen maintenance road generally along the western side of the arroyo. The project also includes improving access to facilitate the removal of trash and debris from stormwater flows. Completion of the construction is expected to take approximately 120 calendar days and is currently scheduled to be complete in November 2020. Please check back for updates.
AMAFCA and the City of Albuquerque are committed to protecting surface and groundwater quality in our community.
Albuquerque Underground, Inc. (AUI) is the completion contractor for the project. Please contact our project manager Patrick Chavez, PE, with any questions, comments, or suggestions regarding this project by phone (884-2215) or email (email@example.com).
Week of October 19-23, 2020 – Construction Update: This week, the contractor will focus on grading and channel slope protection measures in Cars 4 and 5, near Spain Road. Early in the week there will be some work in Cars 1 and 2 related to the valley gutters and debris screens. The contractor has a water truck on site to help keep wind-blown sediment to a minimum. Planned construction activities this week will also include hauling dirt as well as needed construction materials to and from the project site with large trucks. The designated haul route for the trucks will be through American Heritage to Spain Rd. Track out of sediment from the arroyo will continue to be monitored and cleaned up on a daily basis. Vehicular speed of construction equipment will be strictly controlled in the neighborhood.
Week of October 12 – 16, 2020 Lower Bear 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!
