For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

IRMI Expert Commentary: NY Highest Court Confronts Downstream Risk Transfer for Subcontractor Bodily Injury Claims

March 17, 2026 — Gregory D. Podolak & Alexander G. Hopkins - Saxe Doernberger & Vita, P.C.
Originally published on IRMI.com, copyright 2026 International Risk Management Institute, Inc. Subcontractor employee bodily injury claims (so-called action over claims) are a staple of construction risk management in the Empire State—so much so that the phrase “labor law” instinctively invites a shudder among the most experienced general contractors. The savvy among them intensely monitor case law developments and the evolution of the insurance market to ensure a cutting-edge, meticulously developed downstream risk transfer plan. And when guidance arrives from an appellate-level court, it’s a moment to take note. This is one of those moments. In late 2025, New York’s highest court—the NY Court of Appeals—had the rare opportunity to examine an all-too-routine bodily injury fact pattern and took the opportunity to closely examine the scope of contractual indemnity and its interplay with additional insured coverage in Dibrino v. Rockefeller Center N., Inc., 2025 N.Y. Slip Op. 07077, 2025 WL 3670593 (Ct. App. Dec. 18, 2025). Reprinted courtesy of Gregory D. Podolak, Saxe Doernberger & Vita, P.C. and Alexander G.

Water Reuse Emerges as a Critical Strategy for Data Center Development

June 22, 2026 — Ashleigh Myers, Jillian Marullo & Jason Drogin Atwood - Gravel2Gavel Construction & Real Estate Law Blog
As demand for data centers continues to accelerate, water availability is emerging as a critical factor in project development and long-term operations. Although power supply and transmission access have historically dominated siting discussions, increasing water constraints in many regions are placing greater focus on the substantial volumes of water required to support data center cooling systems. As we covered previously, data centers are frequently located in areas already experiencing water stress and require substantial volumes of water to operate—roughly 228 billion gallons in 2023 in the United States alone—with water use projected to increase by up to 170% by 2030. Alternative cooling options, such as free-air cooling or mechanical chillers, can reduce direct water consumption but introduce their own tradeoffs. Free-air cooling is climate-dependent and often ineffective in hotter regions, while mechanical chillers increase energy demand, potentially shifting water consumption upstream through increased electricity generation.

Building in Arizona’s Data Center Boom: How Federal Executive Orders, State Regulation, and National-Security Policy Are Reshaping the Rules for Developers

June 02, 2026 — Ryan J. Regula - Snell & Wilmer
Developers and practitioners evaluating data center projects in Arizona face a regulatory environment shifting on three fronts simultaneously. Federal executive orders are opening new land, streamlining permitting, and channeling financial incentives toward qualifying projects — but they are not preempting the state and local rules that most directly affect project economics. A carve-out in the December 2025 Artificial Intelligence (AI) Framework Executive Order preserves Arizona’s authority over data center infrastructure, meaning the Arizona Corporation Commission’s (ACC) rate-classification docket, municipal zoning restrictions, water-use ordinances, and pending grid cost-allocation legislation remain the binding constraints on project feasibility. Understanding where federal tailwinds end and state and local headwinds begin is essential for any developer sizing risk or selecting sites in the state. The Federal Landscape: An Interlocking Framework of Executive Orders Five interlocking executive orders are accelerating data center development nationally, but none overrides Arizona’s authority over siting energy, or infrastructure.

Louisiana Enacts Important Tort Reform Legislation

May 12, 2026 — Lee M. Peacocke & Benjamin Perkins - Lewis Brisbois
The Louisiana legislature enacted tort reform legislation in 2025 to address the increasing cost of insurance in Louisiana and to provide some predictability to the Louisiana legal system. While our colleagues, Jenny Michel and Jennifer Kretschmann, have provided an excellent and comprehensive analysis of the legislation in their article entitled “Louisiana State Legislature 2025 Regular Session: Tort Reform - Acts & Vetoed Insurance Bill,” which can be found here, this article examines the anticipated impact of the tort reform legislation on personal injury trials in federal and state courts in Louisiana. The most significant reform involves the institution of a modified defense of contributory negligence, which went into effect on January 1, 2026. Since 1996, Louisiana had operated as a pure comparative fault state; the liability of each party whose fault caused damages was to be allocated among the respective parties based upon their appropriate percentage of fault, regardless of the legal theory of liability asserted against each party. Thus, a plaintiff 55 percent at fault could recover 45 percent of their damages from the liable defendants. The 2025 Tort Reform Amendments now prohibit a plaintiff in a personal injury action from recovering any damages if they are found to be 51 percent or more at fault for their damages. The 55 percent at-fault party in the example above is now prohibited from recovering any damages from any party. Importantly, this new legislation now requires the trial court to instruct the jury that if they find a plaintiff to be more than 50 percent at fault, then the plaintiff will not recover any damages.

EPA, Maryland Sue DC Water Over Massive Potomac River Sewage Spill

May 14, 2026 — Jim Parsons - Engineering News-Record
The state of Maryland and the federal government have filed separate lawsuits against the District of Columbia Water and Sewer Authority (DC Water), both alleging that the agency’s failure to address longstanding deterioration in the Potomac Interceptor contributed to a weeklong release of more than 240 million gallons of raw sewage into the Potomac River this past January.

The Modern Nuclear Renaissance Reaches New England

April 14, 2026 — Stephen J. Humes - Gravel2Gavel Construction & Real Estate Law Blog
On March 31, 2026, the governors of all six New England states issued a joint, bipartisan statement committing the region to explore deployment of advanced nuclear energy technologies while supporting the continued safe, affordable and reliable operation of New England’s existing nuclear generation facilities. This coordinated regional initiative follows a major policy announcement in June 2025 by New York Governor Kathy Hochul directing the New York Power Authority to pursue development of at least 1,000 MW of advanced nuclear generation to support statewide reliability needs and New York’s zero‑carbon mission. Less than one year after New York formally embraced a modern nuclear renaissance, that renaissance has now expanded across the New England states—signaling a broader Northeast regional pivot toward nuclear as a core element of long‑term reliability, affordability and decarbonization strategies. For utilities and power generators, this shift creates both opportunities and planning imperatives that warrant immediate attention. Read the full story...

Leaders in Dispute Resolution Need to Make Unbiased Decisions for Mediation to Succeed

March 31, 2026 — Rick G. Erickson - Snell & Wilmer
As a mediator helping to settle construction disputes and as an arbitrator deciding outcomes of these disputes, I found certain lessons to be especially helpful after graduating last summer from the Executive Education program at Harvard Kennedy School (HKS). The exceptional HKS curriculum included courses focused on negotiation strategies for multiparty disputes, decisive leadership during crisis, and human behavior affecting dispute resolution. In particular, our HKS class debated the impact of cognitive bias in dispute resolution, and we studied a central theme that decision-making is universally scientific. That is, parties making decisions in dispute resolution exhibit and rely upon empirical factors that good mediators and decision makers should appreciate and understand. Bias, for example, can cause key players to discount persuasive witnesses, admissible evidence, and reliable expert opinions that influence the outcome of a construction dispute. Biased decision makers may also choose to withhold key information from the mediator, as though doing so will help rather than hurt what is supposed to be an objective and diplomatic process.
