Storm Water Plan Case Study
Global was contracted by a local Road Commission site. The Road Commission site serves as the county level road agency, which maintains more than 1,813 miles of roads and streets and over 250 signalized intersections. The Road Commission contains six sites across the county. Each site is responsible for its particular area. The sites all include maintenance garages, diesel and gasoline ...

Don’t Forget about Stormwater Management
Whether you’re an industrial maintenance manager or retail store manager, one of your many responsibilities may be to keep your property compliant with environmental rules and regulations. From waste management to vapor intrusion, the multitude of compliance-related issues can be daunting.It therefore comes as no surprise that for most retailers, the issue of stormwater management has not always ...

Calibration of a 1D/1D urban flood model using 1D/2D model results in the absence of field data
Recently increased flood events have been prompting researchers to improve existing coupled flood-models such as one-dimensional (1D)/1D and 1D/two-dimensional (2D) models. While 1D/1D models simulate sewer and surface networks using a one-dimensional approach, 1D/2D models represent the surface network by a two-dimensional surface grid. However their application raises two issues to urban flood ...

Assessing the performances of low impact development alternatives by long-term simulation for a semi-arid area in Tianjin, northern China
For areas that are urbanized rapidly, the practice of low impact development (LID) has gained an important place in stormwater management and urban planning due to its capability and beneficial effects in restoring the original hydrological cycle. The performances of LID alternatives can vary substantially due to different climate conditions. This study investigated the performances of five LID ...

Weathering the Storm
Construction excavation and earthmoving recently got a bit more complicated as Phase II of EPAs Storm Water Final Rule went into effect this past spring. The change creates potential for rental dealers who specialize in construction equipment to capitalize on a unique opportunity. While the subject seems new to some, Phase II originated from a 1992 court decision handed down in a lawsuit against ...

Monitoring Surface Runoff in Stormwater Management
Rain supplies moisture that nurtures plant and animal life. Natural precipitation fills water reservoirs so that human residents can have everyday lives. However, as rainwater flows through the landscape, it can cause erosion, flooding, and water damage. Intentional stormwater management must also incorporate plans for surface runoff. ...

EHS support for a manufacturing facility closure – Case Study
Challenge: Antea Group was retained to provide Environmental, Health and Safety (EHS) management services for an audio equipment manufacturer in support of closure of a large manufacturing facility in the Southeastern US. Solution: Duties included waste management inspections and shipping supervision, inspections of fire suppression equipment and petroleum storage tanks, as well as Spill ...

Distributed urban storm water modeling within GIS integrating analytical probabilistic hydrologic models and remote sensing image analyses
Analytical probabilistic hydrologic models (APMs) are computationally efficient producing validated storm water outputs comparable to continuous simulation for storm water planning level analyses. To date, APMs have been run as spatially lumped or semi-distributed models relying upon calibrated and spatially averaged system state variable inputs/parameters limiting model system representation and ...

Even small sites must follow best practices to control erosion and runoff
Since 1990, construction sites larger than 5 acres and municipal separate storm sewer systems (MS4s) serving populations over 100,000 have had to abide by the rules of the Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) Storm Water Program. This program was put in place to protect the country’s waterways from sedimentation buildup. On ...

Storm Water Pollution Prevention Plans
Why Your Railroad Facility Needs One and What to do About It Did you know that that railroad facilities are subject to the Clean Water Act? This includes requirements to have a Storm Water Pollution Prevention Plan (SWPPP) in place to clarify how you will control pollutants in storm water runoff from your facility. A SWPPP will identify the potential sources of pollution and describe the ...

Auto Dealer Expands While Steering Clear of Stormwater Pitfalls
The owner of Schmelz Countryside Saab/Volkswagen wanted to expand the parking lot for his auto sales business in 2003. However, the city stormwater ordinance threatened to wreck those plans. Thankfully, the professionals at Advanced Pavement Technology (APT) were able to put Schmelz back on the road for a smooth ride with an environmentally friendly permeable paving system that solved all of his ...

What to consider: Selecting the right electronics recycling & asset management vendor
As the sales executive with an R2 & ISO-14001 certified electronics recycling, scrap purchasing, and asset management corporation, I could write all day about why I think Dynamic Recycling should be your e-recycling vendor. I would rather provide you with the appropriate information to conduct your own evaluation/analysis of what to look for in choosing a recycler that is the right fit for ...

Storm Water Master Plan development employing an integrated 1D/2D model for the Redwood Basin in Josephine County, Oregon - Case Study
The use of two-dimensional (2D) storm water models has increased in recent years primarily due to advances in software, hardware and the availability of surface data. These advances allow for robust and diverse applications including basinwide storm water assessments. Storm water master planning is a critical element for the development of state and local agency comprehensive plans, capital ...

Stormwater Treatment: Priority pollutant behaviour in stormwater BMPs
The term Stormwater Best Management Practices (BMPs) (also known as sustainable urban drainage systems; SUDS) refers to a wide range of stormwater control systems which enable the planning, design and management of stormwater to be tackled equally from water quantity, water quality and amenity perspectives (). Commonly used systems include: Storage systems (e.g. retention ponds and constructed ...

Info-Gap robustness pathway method for transitioning of urban drainage systems under deep uncertainties
In the urban water cycle, there are different ways of handling stormwater runoff. Traditional systems mainly rely on underground piped, sometimes named ‘gray’ infrastructure. New and so-called ‘green/blue’ ambitions aim for treating and conveying the runoff at the surface. Such concepts are mainly based on ground infiltration and temporal storage. In this work a methodology to create and ...

Synergistic benefits between stormwater management measures and a new pricing system for stormwater in the City of Hamburg
Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain ...
