The Rhode Island Department of Transportation (RIDOT) plans to launch its first-ever statewide inventory of highway drainage systems. RIDOT estimates that it is responsible for 25,000 stormwater catch basins, 2000 outfalls, and 100 structural stormwater controls. However, this new endeavor will be the state’s first full inspection and inventory of its system. This inventory will […]
Nine case studies show how communities across the U.S. are developing tools to overcome stormwater challenges. These solutions will be presented at the 2015 Stormwater Congress.
On April 8, the Missouri Department of Transportation (MoDOT) agreed to implement a statewide compliance program and to pay a $750,000 civil penalty to settle alleged Clean Water Act violations at two road construction sites. According to the U.S. Environmental Protection Agency, two sites inspected in 2010 and 2011 had significant erosion control issues, including […]
The use of road salt and other deicers for highway maintenance became widespread during the 1960s. And while salting allows for safer winter travel, sustained economic productivity, continued emergency services, and other benefits, salt has been silently accumulating in the environment ever since, threatening drinking water supplies and aquatic ecosystems. According to a U.S. Geological […]
On Dec. 16, federal government representatives, Virginia Governor Terry McAuliffe, and others came together to recognize an innovative, market-based nutrient trading program run by Virginia to improve Chesapeake Bay water quality. The U.S. Environmental Protection Agency, U.S. Department of Agriculture, and the White House Council on Environmental Quality lauded the trading scheme as a model […]
Cold-climate researchers at the Center for Environmentally Sustainable Transportation in Cold Climates (CESTiCC) are looking at green alternatives to the salt, sand, and chemicals typically used for highway snow and ice control. The U.S. spends $2.3 billion each year on the removal of highway snow and ice plus another $5 billion to mitigate the hidden […]
In addition to required environmental work, the California Department of Transportation (Caltrans) will fund the Mariposa Supplemental Environmental Project. The project will provide real-time monitoring along a wild and scenic stretch of the Merced River to detect excess turbidity and pH levels during Caltrans’ Ferguson landslide rehabilitation project. Data will be collected both before and […]
Colorado Department of Transportation’s new erosion control training is complimented by a newly renovated facility for hands-on learning.
In August, Minnesota Department of Transportation (MnDOT) Research Services & Library released a report “Assessing and Improving Pollution Prevention by Swales.” Researchers found substantial spatial variability in swale infiltration rate. This report discusses how roadside swales can be used to their full pollution prevention potential and cost-effectiveness, covering maintenance schedules and efforts. They also developed […]
In mid-May, the National Cooperative Highway Research Program (NCHRP) released the report “Measuring and Removing Dissolved Metals from Stormwater in Highly Urbanized Areas.” The issue of dissolved metals is coming to the forefront in stormwater management and is an increasing concern for regulatory agencies. This is especially true in urbanized areas with limited space for […]
