Tag: stormwater runoff

Surface runoff (also known as overland flow) is the flow of water that occurs when excess stormwater, meltwater, or other sources flows over the earth’s surface. This might occur because soil is saturated to full capacity, because rain arrives more quickly than soil can absorb it, or because impervious areas (roofs and pavement) send their runoff to surrounding soil that cannot absorb all of it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water.

Porous Pavers: Improving Water Quality

Porous Pavers: Improving Water Quality

Permeable pavement is taking center stage now as erosion control and stormwater green infrastructure projects aim to reduce runoff and improve water quality.

Stopping Nonpoint-Source Pollution
In Columbia, MO, the Public Works Department received a Clean Water Act 319 grant for stormwater improvements to reduce nonpoint-source pollution into the creeks and streams.

PAVEDRAIN
The PaveDrain system is a patented, permeable paving surface designed with the joints between the blocks left open for an unprecedented infiltration rate (i.e., no rocks). Maintenance is accomplished with conventional street vacuuming equipment or the PaveDrain Vac Head. PaveDrain is ADA compliant, HS-25 load rated, manufactured throughout the US,

An Approach for Communities to Assess Stormwater Application and Detention Requirements for Overall Watershed Health

An Approach for Communities to Assess Stormwater Application and Detention Requirements for Overall Watershed Health

Communities, especially those with limited resources, face many issues when trying to protect their local watersheds through the use of stormwater policies. Stormwater policies that are imposed on new development have the ability to enhance a community’s overall watershed health (Ferguson 1998). However, past requirements often relate only to large

One Way to Get Their Attention

Last December, a sinkhole opened up in the town of Fraser, MI—on Christmas Eve, no less. The cause was a broken 11-foot-diameter sewer pipe located 55 feet underground. The hole eventually measured 250 by 100 feet, causing nearly two dozen homes to be temporarily evacuated. A few are damaged so

Structural Integrity That Lasts

Structural Integrity That Lasts

Capping and closing a municipal solid waste (MSW) landfill can be a civil engineering challenge. The goal is to eliminate any need for further erosion control work onsite to ensure that the landfill keeps its structural integrity. True, landfill owners are required to adhere to EPA’s post-closure rules as defined

The First Line of Defense: Protecting Inlets and Storm Drains

The First Line of Defense: Protecting Inlets and Storm Drains

In stormwater management for both temporary and post-construction measures, inlet and storm drain protection is one of the first lines of defense. It’s also a measure that often works in combination with other best management practices (BMPs) as part of an overall erosion control or stormwater management program.

Challenges of Urban Water Infrastructure

Challenges of Urban Water Infrastructure

AT PRESENT, 80.7% OF the US population resides in urban areas (US Census Bureau 2012). Increased urbanization (paved areas and buildings) and urban population growth has exerted significant pressure on urban water demand and expansion of urban water infrastructure—i.e., potable water supplies, wastewater treatment and discharge, and urban stormwater runoff
