The City of Austin, Texas, has played a pioneering role in the control of urban nonpoint source pollution by enacting watershed and stormwater ordinances, overseeing detailed monitoring...
Design and Construction of Infiltration Trenches
This paper discusses the use of infiltration trenches as a stormwater management practice. Feasibility, design and construction techniques are presented to improve the performance and...
Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...
Institutional Aspects of Stormwater Quality Planning
Planning and implementation of programs to control the quality of stormwater runoff in urban areas are carried out within institutional frameworks that directly influence the effectiveness...
Institutional Stormwater Management Issues
Research, innovation, and structure performance are necessary components of an overall stormwater management program, but program success or failure rests on its institutional framework....
Urban Runoff Management?An Industry Perspective An Opinion
Coors presently produces about 17 million barrels of beer per year from a single plant about 15 miles west of Denver. The company chose to keep the responbibility for the quality of its...
Summary of Institutional Issues

Swirl Concentrators Revisited. The American Experience and New German Technology
The Swirl Concentrator is a small, compact, 'no moving parts' solids separation device. Its function is to act as as a static combined sewer overflow (CSO) regulation...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Program to Reduce Deicing Chemical Usage
Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation....
Long-Term Effects of Urban Stormwater on Wetlands
In 1986 scientists and managers associated with local, state, and federal agencies that have wetland protection and stormwater management responsibilities in the region joined to consider...
Civil Engineering at the Threshold of the 21st Century: Focus on the Emerging Professional Environment
The development of America's surface transportation into the 21st century confronts the civil engineer with a distinctively new challenge arising from the twin demands of...
Implementing a State PMS
Arizona State Pavement Management System (PMS) is described in this paper. Experience shows that many factors must be considered in deciding how to maintain a particular mile of the road...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
Future Federal Pavement Policy
Pavement design is entering a new era of increased attention and research insight. Since most of our pavements are in place and under traffic, much of future design will be for their rehabilitation...
America's Changing Demographics: Impacts on Transportation Requirements
Present and future demographic changes in the United States will significantly impact future transportation requirements. These changes include a redistribution of the nation's...
21ST Century T2 for Local Transportation Managers
A plausible scenario to 21st Century technology transfer for local road and street managers is presented. The future needs of local managers and their level of expertise is addressed within...
What Will Happen to Local Rural Roads and Bridges
Much of the local rural road and bridge system was not designed for the heavy trucks and farm equipment that are currently using the system. The system will continue to deteriorate unless...
