But What Are You Doing About the Owl Habitat?!

| What seemed simple on the surface became complicated in a hurry. In May 2015, we had a plan to resolve persistent flooding issues in the Rolling Hills neighborhood (Figure 1) through a series of stormwater projects involving large box culverts and open channel work. Work was phased from the upstream end to downstream due to ... READ MORE

A Piece of the Puzzle

| Long-time football coach Vince Lombardi once said that the greatest accomplishment isn’t in never falling, but in rising again after you fall. Cleveland, OH, a city once known for industrialized manufacturing and a major hub on the Cuyahoga River, experienced a fall of sorts in 1969 by way of river fire. The fire that would ... READ MORE

IDDE Programs Revisited

| Today, the once-ritual Sunday dinner at Grandma’s has largely fallen to the wayside and is a memory of a bygone era. But for those of us who can remember it, the post-meal cleanup after these gastronomic events had specific protocols that recalled Depression-era deprivation and the “waste not, want not” philosophy. First, all the uneaten ... READ MORE

Cold Weather Stormwater Management

| As the winter season commences, stormwater management shifts to cold weather practices in much of the US. It brings inherent challenges, especially the effects of deicing salt, sand, and chemicals and concerns about runoff into nearby water bodies. ... READ MORE

Summary of ASCE Stormwater Manufactured Treatment Devices Certification Guidelines

| With the advent of EPA’s National Pollutant Discharge Elimination System (NPDES) permits and subsequent total maximum daily load (TMDL) permits, many local, state, and industrial entities are obligated to treat stormwater runoff before discharging to receiving waters. Common treatment methods such as retention ponds, detention ponds, and wetlands can achieve economies of scale where land is available for large best management practices (BMPs). ... READ MORE

Sweeping Their Way to Clean Water

| In 2013, the Ada County Highway District (ACHD) in Idaho received a National Pollutant Discharge Elimination System (NPDES) Phase I permit. The shared permit authorizes stormwater discharge for the cities of Boise and Garden City. ... READ MORE

Restoring Euclid Beach

| By the end of the 19th century, Americans were enjoying the benefits of shorter work hours and new technologies. The cultural overhaul included the popularity of outdoor exercise and fresh air, and that sparked the advent of amusement parks, beach bathing, and other outdoor entertainments. Typically situated on lake or ocean shores, with access by special trolley trains, these warm-weather attractions brought crowds away from the urban heat for bathing, refreshments, and eventually amusement rides such as carousels and roller coasters. ...

Managing Trash and Contaminants With Screens and Storage

| Every year, Heal the Bay, a nonprofit advocating for coastal water quality in the Los Angeles region, lists all the beaches in Los Angeles County and grades them based on visual experiences, the quality of the water, the quality of the beach, and its cleanliness. Each year the annual report lists some of those beaches on its Beach Bummer List—a compendium of the dirtiest, least desirable, and most inhospitable attractions on the Los Angeles coastline. For several years, the beach surrounding Santa Monica Pier, a recreational attraction that hosts over 6 million visitors every year, has had the dubious distinction of holding a prominent position on that list. “Many factors contribute to that,” says Selim Eren, an engineer with the city of Santa Monica. “Having restaurants on the pier and having an open timber structure and a dark and moist environment under the pier doesn’t help, overall, the situation there.” ...

Why Presenting “Just the Facts” Fails

| It was only a few seconds, but to Randy it seemed like it took an hour to reach the front of the community room. He was numbed by the audience’s animosity—many had come solely out of curiosity, but others seemed to harbor a personal vendetta. As he approached, he saw his team of experts—hired consultants—already in place flanking the podium. ... READ MORE

The Many Faces of Permeable Pavers

| The world of permeable pavers is multifaceted. They come in a variety of shapes and sizes. They can be placed in a wide range of configurations to match tastes, function, or budgets. They can play a central role in meeting a wide variety of water-quality improvement goals. Projects employing permeable pavers are as varied as the capabilities of the technology, ranging from roadways to schoolyards to footpaths or platforms. While engineers rely on them to perform two central functions—supporting whatever traffic they are expected to bear and allowing water to infiltrate beneath the surface—they can do much more. Whatever the duty permeable pavers are called upon to perform, they can take it on with grace and style. ... READ MORE
