The Los Alamos County Council convened on July 29, 2025, to discuss significant developments regarding the Twentieth Street redevelopment project, led by RBMM Development LLC. The meeting featured presentations from county officials and the development team, outlining plans for revitalizing a key downtown parcel.

Dan Osborne, the housing special projects manager for Los Alamos County, introduced the redevelopment concept, emphasizing its alignment with the Los Alamos downtown master plan adopted in October 2021. The proposed site, located at the intersection of Trinity Drive and Twentieth Street, spans approximately three acres and has been underutilized in recent years. The redevelopment aims to transform the area into a vibrant mixed-use space that includes residential units, retail options, and public amenities.

Osborne highlighted the importance of public input in shaping the project, noting that community feedback was gathered through meetings, surveys, and workshops. The redevelopment is designed to enhance connectivity between the Canyon Rim Trail and Ashley Pond, creating a pedestrian-friendly environment that encourages social interaction and supports local businesses.

The proposed development includes plans for mixed-use buildings, with a focus on higher density housing to meet the needs of a growing population. The project aims to provide approximately 25,000 square feet of retail space, catering to small, locally owned businesses. Additionally, the development will feature public spaces, including parks and an amphitheater, to foster community engagement.

Russell Bratt, managing member of RBMM Development, expressed enthusiasm for the project, emphasizing its potential to create a lively downtown ecosystem. He noted that the design prioritizes walkability and accessibility, allowing residents to meet their daily needs without relying on cars.

The council discussed the financial aspects of the project, including the proposed purchase price of $1,770,000 for the property and the developer's commitment to public infrastructure improvements. These improvements include new traffic signals, pedestrian crossings, and enhanced streetscapes, all aimed at integrating the development into the broader downtown area.

Council members raised questions about the project's focus on market-rate housing, with assurances from Osborne that the county is also pursuing a range of housing options, including deed-restricted units, to address diverse community needs.

The council is expected to review a draft development agreement and ordinance for formal introduction at their next meeting on August 5, 2025. This redevelopment initiative represents a significant step towards revitalizing downtown Los Alamos, enhancing its appeal as a vibrant, family-friendly community hub.
