U.S. stainless steel bar producers invoke antidumping duty terms for Indian peers

Sources: Kelley Drye & Warren LLP, Washington, D.C.; CP staff

Through the U.S. Department of Commerce, seven domestic stainless steel bar producers have filed a request for changed circumstances reviews, arguing that Viraj Profiles and Venus Wire Industries Pvt. Ltd. should be immediately reinstated back under the existing antidumping duty order on competing product from India. Following respective 2004 and 2011 revocations from the order, they contend, Viraj Profiles and Venus Wire resumed dumping concrete reinforcing and other stainless steel bar products in the U.S.

Landscape architects embrace resilient design principles

ASLA’s new online guide [https://www.asla.org/resilient] explains how communities can better protect themselves from natural disasters through resilient landscape planning and design, including strategies to help control flooding through such green infrastructure as pervious or permeable pavements.

Resilient Design Guide examines extreme precipitation, landslides and other disruptive events like drought, extreme heat, and fire. It offers case studies and resources demonstrating multi-benefit systems plus small-scale solutions, and explains landscape architects’ role in the planning and design teams seeking to make communities more resilient. Resilient design involves working with instead of opposing nature, ASLA notes, and provides value through:

Risk reduction. As events become more frequent and intense, communities must adapt and redevelop to reduce potential risks and improve ecological and human health. Planning and permitting authorities need to stop the development of communities and infrastructure in high-risk places;

Scalability and diversity. Resilient landscape planning and design offers a multi-layered system of protection, with diverse, scalable elements, any one of which can fail safely in the event of a catastrophe;

Multiple co-benefits. Resilient landscape design solutions offer multiple benefits at once. Green infrastructure designed to manage extreme precipitation and routine stormwater volumes, for example, also provides community space and creates jobs; and,

Regeneration. Disruptive natural events—occurring more frequently worldwide than in the past—harm people and property; resilient design helps communities come back stronger. Long-term resilience is about continuously bouncing back and “regenerating.”

ASLA’s Resilient Design Guide has been developed with participation of Yale University School of Architecture and University of California, Berkeley faculty.
