New Orleans Drainage System Recognized as Historic Civil Engineering Landmark

May 29, 2023 — The American Society of Civil Engineers
NEW ORLEANS, La. – The American Society of Civil Engineers (ASCE) today recognized the New Orleans Drainage System in New Orleans, Louisiana as a Historic Civil Engineering Landmark. The project was innovative and largely unprecedented for its time, and the first portions came online in the year 1900. The system now consists of 22 drainage pumping stations and 1,200 miles of network drains, as well as green infrastructure elements to manage stormwater runoff. The infrastructure is largely credited for making the existence of New Orleans possible, and the improved drainage and reduction in standing water contributed to better public health and reduced the number of malaria and typhoid deaths in the early 20th century. New Orleans' position near the mouth of the Mississippi River made it a vital city for trade and commerce in the U.S. economy since the early 1800s, despite its problematic natural environment. The city was perched along the banks of the Mississippi River and next to Lake Pontchartrain, surrounded by swamps. Improvements to levee systems prevented the city from being inundated with flooding from the river, but rainfall became a pervasive issue as the city's population grew in the 1870s. The drainage system was first proposed in 1876 to replace primitive "drainage machines," steam-powered paddle wheels that moved water runoff into canals that led to Lake Pontchartrain. The existing system was inefficient and could not handle the frequent, heavy tropical rain New Orleans experiences and could not lift water sufficiently to drain the city. After several proposals, construction on the current drainage system started in 1897, and the first portions of the system came online in 1900. The system drains stormwater through pipes and canals to reach drainage pump stations which expel the water into several bodies of water surrounding the city. Engineers have repeatedly expanded and enlarged the drainage system, including a massive investment in the drainage system authorized by the Southeast Louisiana Urban Flood Control Project and approved by Congress in 1996. The Sewerage and Water Board's green infrastructure plan is a critical partner and complement to the drainage system today. The New Orleans Drainage System's design has inspired water management system design in communities around America and worldwide. In Southeastern Florida, water management systems using pumps and canals divert excess water away from heavily populated areas during heavy rain, including tropical storms and hurricanes. Engineers in Kolkata, India and Shanghai, China have also used drainage and pumping systems like the ones in New Orleans to assist with water management. ABOUT THE AMERICAN SOCIETY OF CIVIL ENGINEERS Founded in 1852, the American Society of Civil Engineers represents more than 150,000 civil engineers worldwide and is America's oldest national engineering society. ASCE works to raise awareness of the need to maintain and modernize the nation's infrastructure using sustainable and resilient practices, advocates for increasing and optimizing investment in infrastructure, and improve engineering knowledge and competency.

Diggin’ Ain’t Easy: Remember to Give Notice Before You Excavate in California

February 15, 2018 — Matthew Peng – Construction Law Blog
If you are reading this blog, my guess is that you know what excavation is and why it is important to the construction process. However, what you may not know is the complicated California law that governs this process. The statute for an excavation contractor to be familiar with is California Government Code section 4216, et seq. However, like most things worth pursuing, that is easier said than done. Section 4216 contains several layers of prerequisites and requirements. This article will explore the notice requirement. Section 4216.1 requires “every operator of a subsurface installation” to share costs of a regional notification center. This is necessary because Section 4216.2(b) requires “an excavator planning to conduct an excavation shall notify the appropriate regional notification center of the excavator’s intent to excavate” before beginning that excavation. The statute lists two regional notification centers: the Underground Service Alert—Northern California and the Under Ground Service Alert—Southern California. Read the court decision

Forget Backyard Pools, Build a Swimming Pond Instead

June 17, 2015 — Mark Ellwood – Bloomberg
No self-respecting Californian can let the summer pass without a dip in the backyard—pools are as much a part of culture as the 49ers, Schwarzenegger, and dire earthquake warnings. Now, though, there’s something unseemly about pooling so much water for the occasional swim—enough, in fact, to generate its own hashstag, #droughtshaming. There’s one surefire way to mitigate opprobrium: Build a natural swimming pond that’s specifically designed to minimize environmental impacts (or the cash premiums required to keep it up). Typical is one example in Sonoma County, where the the water seems to leak down from the rock perched on the ridge. Like a natural spring, it trickles and tumbles, pooling into water features as it falls; one feature is full of aquatic plants and flowers, while another is a swimming hole—clear, cool and inviting. It was built by Dave Whitney, chief executive officer of Eco Solutions, a pioneer in engineering such eco swimming ponds. These dipping pools use natural filtration instead of chlorine pellets to keep the water clean. Read the court decision

Construction Termination Issues Part 6: This is the End (Tips for The Design Professional)

September 25, 2023 — Melissa Dewey Brumback - Construction Law in North Carolina
Whether your role is in helping analyze the contractor’s work on the project to certify a contractor’s termination for cause, or you are being shown the door yourself, and everything in between, termination is a subject that is ripe with potential problems. Consider these summary tips as part of your practice, every time the termination idea arises:

Remember that you are the neutral and must be impartial between Owner and Contractor
After you have made a fair decision, document your decision to the Owner and Contractor
Provide options less nuclear for Owners– stop work; removing scopes of work; etc.

A Closer Look at an HOA Board Member’s Duty to Homeowners

August 27, 2013 — Derek Lindenschmidt — Higgings, Hopkins, McLain & Roswell, LLC
Whenever a homeowner association (HOA) starts thinking in terms of a construction defect lawsuit against its developer and/or builder, its board members will inevitably be confronted with the purported risk and liability to their homeowners if they do not pursue the alleged defects and deficiencies brought to their attention. Not surprisingly, the board members are on occasion led to believe that pursuing such claims is synonymous with acting in the homeowners’ “best interests.” Further—and unfortunately—board members often feel as though they will breach their obligation to the homeowners if theydon’t agree to proceed with such claims. Nevertheless, how well do we really know what the board members’ duty actually consists of, when it applies, and what potential liability exists for a board member’s breach of same? The answers might surprise you. Read the court decision

A Court-Side Seat: Clean Air, Clean Water, Endangered Species and Deliberative Process Privilege

April 19, 2021 — Anthony B. Cavender - Gravel2Gavel
The federal courts have issued some significant environmental law rulings in the past few days. THE U.S. SUPREME COURT U.S. Fish and Wildlife Service v. Sierra Club, Inc. On March 4, 2021, the court held that the deliberative process privilege of the Freedom of Information Act shields from disclosure in-house draft governmental biological opinions that are both “predecisional” and deliberative. According to the court, these opinions, opining on the Endangered Species Act (ESA) effects on aquatic species of a proposed federal rule affecting cooling water intake structures—which was promulgated in 2019—are exempt from disclosure because they do not reflect a “final” agency opinion. Indeed, these ESA-required opinions reflect a preliminary view, and the Services did not treat them as being the final or last word on the project’s desirability. The Sierra Club, invoking the FOIA, sought many records generated by the rulemaking proceeding, and received thousands of pages. However, the Service declined to release the draft biological opinions that were created in connection with the ESA consultative process. Read the court decision

OSHA Begins Enforcement of its Respirable Crystalline Silica in Construction Standard. Try Saying That Five Times Real Fast

November 02, 2017 — Garret Murai - California Construction Law Blog
On October 23, 2017, the U.S. Occupational Safety and Health Administration (OSHA) began enforcement of its Respirable Crystalline Silica in Construction Standard (Construction Silica Standard). OSHA enforcement of its Construction Silica Standard actually began on September 23, 2017, but for a period of 30 days, OSHA offered compliance assistance in lieu of enforcement for employers who were making good faith efforts to comply with the Construction Silica Standard. California’s Occupational Safety and Health Administration (Cal/OSHA) has a nearly identical construction silica standard that requires employers to limit worker exposure to respirable crystalline silica above 25 micrograms per cubic meter of air (25 μg/m3) as an 8-hour time-weighted average (TWA) under any foreseeable condition.

Shifting the Risk of Delay by Having Float Go Your Way

July 05, 2021 — Christopher J. Brasco & Matthew D. Baker - ConsensusDocs
Critical path delay plays a central role in allocating responsibility for project delay. The interrelated concept of concurrency is also frequently determinative of entitlement on a range of claims including by owners for liquidated damages and by contractors for delay damages. What constitutes critical/concurrent delay, however, is hotly debated by scheduling experts. The lack of real consensus regarding how critical/concurrent delay should be determined and analyzed has created significant uncertainty in scheduling disputes. Indeed, courts have adopted differing and at times conflicting theories of concurrency that can produce divergent outcomes for the parties. In an effort to reduce uncertainty, stakeholders have increasingly adopted specialized contractual provisions and scheduling techniques which have significant implications for the evaluation of the companion concepts of criticality and concurrency. One such mechanism is float sequestration. Regardless of whether float sequestration is ultimately in the construction industry’s broader interest, stakeholders must be able to recognize its use and appreciate the implications for delay disputes on their projects. Simply defined, float is the number of days an activity can be delayed before affecting the project’s critical path (i.e., the longest chain of activities which determines the project’s minimal duration). Typically, only delays affecting the critical path can produce concurrent delay. Consequently, the concept of float is integral to understanding and resolving issues of both criticality and concurrency. Reprinted courtesy of Christopher J.
