  • Incorporating Social and Environmental Outputs in Decision-Making: Workshop Outcomes

    PURPOSE: This document summarizes the notable outcomes of the workshop “Quantifying and Incorporating Social and Environmental Outputs in Decision-Making—Research and Development Needs and Strategy Workshop.” The workshop was held 24 and 25 July 2019 in Alexandria, Virginia, at the US Army Corps of Engineers’ (USACE) Institute for Water Resources (IWR). The workshop sought to identify gaps in knowledge, methods, data, and tools and to identify types of subject matter experts who would be needed for the research team. A total of 22 participants attended the facilitated workshop, representing a broad array of expertise: economists, scientists, planners, social scientists, project managers, and researchers from a number of USACE organizations and partnering academics across the United States. Together, these attendees reviewed existing policy and research and prioritized future work to fill gaps in methods and procedures for incorporating social and environmental inputs across a broad range of USACE projects.

  • Old Post Reevaluation, Fort Huachuca, AZ

    Abstract: The US Congress codified the National Historic Preservation Act of 1966 (NHPA), the nation’s most effective cultural resources legislation to date, mostly through establishing the National Register of Historic Places (NRHP). The NHPA requires Federal agencies to address their cultural resources, which are defined as any prehistoric or historic district, site, building, structure, or object. Section 110 of the NHPA requires Federal agencies to inventory and evaluate their cultural resources, and Section 106 requires them to determine the effect of Federal undertakings on those potentially eligible for the NRHP. Fort Huachuca is situated at the foot of the Huachuca Mountains in southern Cochise County, Arizona. It is located approximately 15 miles north of the border with Mexico and 75 miles southeast of Tucson. It was founded in 1877 as a frontier cavalry fort and remains one of the oldest military installations in the West. The objective of this report is to inventory the real property within Fort Huachuca’s Old Post, the historic core of the installation. Each resource is enumerated and accompanied by a list of reports discussing its potential NHL or NRHP eligibility. Subsequently, each resource is accompanied by a short description, which includes its location and current status within the recently created Old Post Historic District.

  • Development and Validation of a Balanced Mix Design Approach for CIR Mixtures Using Full-Scale Testing

    Abstract: The main goal of this study was to improve the performance of cold in-place recycling (CIR) mixtures by using a balanced mix design (BMD) approach. This study involved preparing and testing CIR mixtures in the lab at varying contents of bituminous additives and constant content of 1% cement and 3% water. Eight combinations of CIR mixtures were produced for this study using two binders (emulsion and foamed asphalt), compaction efforts (30 and 70 gyrations), and curing processes (72 hours at 140°F and 50°F). Results showed that asphalt pavement analyzer, semicircular bend, and indirect tensile strength tests presented the highest correlation with the change of binder contents. The study successfully used the developed BMD for designing CIR mixtures and selecting their optimum binder contents. It then used three balanced CIR mixtures to construct full-scale pavement sections to validate the BMD approach in the field. A heavy vehicle simulator was used to apply different accelerated loadings on each section. Results showed that the CIR section with 2% binder presented the best rutting performance under truck loading and the highest rutting susceptibility under aircraft loading. Conversely, the CIR section with 3% binder presented the highest cracking resistance under both truck and aircraft loading.

  • President Biden’s Bipartisan Infrastructure Law will invest more than $845 million in U.S. Army Corps of Engineers studies, projects, and programs

    Office of the Assistant Secretary of the Army for Civil Works announced additional U.S. Army Corps of Engineers studies, projects, and programs funded by President Biden’s Bipartisan Infrastructure Law. These actions will invest more than $845 million to address urgent issues facing Americans, including supply chain resilience, flood mitigation, and costal storm damage protection. The U.S. Army Corps of Engineers, Chicago District will receive a portion of those funds totaling around $3.45 million to assist in the completion of several projects across the Great Lakes, specifically the Lake Michigan shorelines of Illinois and Indiana.
