Oroville Dam Spillway Incident: Independent Forensic Report

Oroville Dam Spillway Incident - Thumb

The Oroville Dam spillway incident was caused by a long-term systemic failure of the California Department of Water Resources (DWR), regulatory, and general industry practices to recognize and address inherent spillway design and construction weaknesses, poor bedrock quality, and deteriorated service spillway chute conditions.

Resilience and efficiency in transportation networks

Friday, December 29th, 2017
Fig. 1. Definition of urban areas and assignment of nodes’ population.

It is widely understood that roadway infrastructure is expensive, both in acquiring land for rights-of-way and in construction of improvements, and thus, decisions regarding alignment, crossing, and access made over a period of decades may have long-lasting consequences that are observable in traffic data today. Consequently, urban areas exhibit different unintentional traffic characteristics, including delays under normal and random stress conditions. Investments motivated exclusively by expected efficiencies under normal operating conditions are unreliable safeguards against loss of efficiency under stress conditions. Therefore, new analytic tools are required that allow designers to assess the adaptive capacity of roadway infrastructure and assess the potential of new investments to provide enhanced resilience.

Complete streets in New Orleans: Recommended measures

Complete Streets is a fundamentally different approach to transportation planning, design, and engineering than the status quo of the last half century. It requires that all aspects of decision-making and implementation consider the needs of all people who use a road, regardless of age, ability, or mode of transportation. Streets are viewed as more than ways to move as many vehicles as possible. They are public spaces that connect and contribute to everything that surrounds them.
