By Janis Keating Ask the average citizen about “street sweeping,” and chances are she’ll say, “It cleans up the trash people toss out of their cars.” This is, of course, true, and what most people notice. Minutes after Los Angeles’ 2013 Golden Dragon Parade ended, pedestrians quickly returned to Chinatown’s sidewalks as street cleaners whisked along the parade route, collecting the numerous piles of paper confetti and Mylar streamers shot from and to the crowds. However, street sweeping does much more, ...... continue reading

By Steve Goldberg Protecting Lake Lewisville Rural Texas contains a number of what are termed “farm to market” roads, or “FM” for short. FM 720 is one of those roads, located in Denton County, just northeast of Ft. Worth. The Texas Department of Transportation (TxDOT) is in the process of upgrading the roadway because of population growth in the area. “They’re expanding FM 720 from two to four lanes. Where the road crosses Lake Lewisville, there is an existing double-lane bridge over the lake, and TxDOT...... continue reading

By Daniel Ahern, Richard Wagner, and Robert Klink Beaufort County, SC, is located between Charleston, SC, and Savannah, GA. Because of the prime coastal location, the county has long been an attractive location for resorts and other types of development. The county’s stormwater program has been challenged by its citizens and leaders to be a progressive coastal program that has recently incorporated volume control into its stormwater management criteria. This progressive attitude has kept 85% of o...... continue reading

By Clem Brown and Bryn Evans The city of San Diego, CA, Transportation and Storm Water Department has been aggressively testing assumptions regarding street sweeping and its role as a best management practice (BMP) for stormwater pollution prevention. The city has gathered significant data regarding how to best optimize the use of street sweeping equipment and routes. This article summarizes the city’s findings and makes a strong case for street sweeping improvements nationwide. Background The ci...... continue reading

By Kevin Daggett and Jerry Lovato The Albuquerque Metropolitan Arroyo Control Authority (AMAFCA) has been constructing stormwater-quality facilities and best management practices (BMPs) for more than 13 years. During that time, many different approaches have been tested for effectiveness. The BMP selection process has evolved over time through lessons learned and the incorporation of new methodologies and technologies. AMAFCA’s approach to water quality has evolved to adapt to local hydrologic, hydrauli...... continue reading

There is a mounting challenge throughout North America on how to manage stormwater in urban areas as land becomes more developed, resulting in more impervious surfaces and less space in which to install stormwater treatment devices. Case in point: until recently, the metal recycling efforts of Sims Metal Management Municipal Recycling (SMR) in the Bronx had been a double-edged sword. On one hand, the facility (formerly known as Hugo Neu until a 2005 buyout) has successfully recycled hundreds of tons of ...... continue reading

By Janice Kaspersen This fall marked the 40th anniversary of the Clean Water Act, and along with the occasion came messages from every side—some hailing the CWA as a crowning jewel of environmental policy, others saying it has already been so weakened by recent court cases that it now lacks teeth to protect our waterways, and a few calling for its complete overhaul. There’s no doubt that the CWA has faced, and continues to face, challenges. We have seen years of wrangling over how, precisely, we should ...... continue reading

By Carol Brzozowski Eric Stein is the principal scientist in the biology department of the Southern California Coastal Water Research Project, a public research institute that has been in existence since 1969. “Our main mission is to do science and research to support water-quality management in the region that pertains to streams, beaches, and the ocean. We provide independent technical resources that support the regulators and the regulated,” he says. One of the projects in which Stein has been involv...... continue reading

By Jane Clary, Brandon Steets, Jonathan Jones, Eric Strecker, and Marc Leisenring Pathogens are the top cause of stream impairments nationally, with over 10,500 stream segments identified as impaired as of 2012—typically due to elevated concentrations of fecal indicator bacteria (FIB) in waterbodies. Although strict numeric effluent limits for stormwater discharges are not typically required yet in most communities, the implementation phase of total maximum daily loads (TMDLs) may result in Natio...... continue reading

By Margaret Buranen When Raul Garza sits in the cab of Clean Water Services’ light blue Tymco street sweeper, he sees himself as doing more than earning a paycheck. Driving through the streets of the stormwater utility’s district—parts of Multnomah, Clackamas, and Washington counties in Oregon—Garza knows that the work he is doing is important to keeping the local water supply clean. Garza, a field maintenance technician II, stars in a video Clean Water Services produced as part of the public edu...... continue reading
