Low Volume Roads

This webinar is designed to give an overview of the key design, construction and maintenance issues involved in low-volume roads, with an emphasis on important aspects of road drainage. Best Practices are presented, along with many design and mitigation practices used to help a road achieve its design life, be cost-effective, and minimize adverse environmental impacts. Drainage is emphasized since an old saying goes, “The three of the most important aspects of road design are Drainage, Drainage, and Drainage!” These include surface drainage and the use of culverts, low-water crossings, and bridges. Low-volume roads make up 60 to 70 percent of all roads worldwide. In the United States there are over 2.5 million miles of low-volume roads. On those roads major investments are made in the materials used for surfacing, in drainage crossing structures, and in the maintenance of the roads. Thus understanding the many aspects of roadway design and drainage are important to achieve good designs, to protect our investment in the roads, to minimize damage from storms, to minimize maintenance costs, and to protect water quality near the road and at crossings. This Webinar will briefly address the importance of slope stability issues, use of roadway materials, proper erosion control, and the many aspects road surface drainage used to keep water off the road surface and to avoid concentration of water. These include maintaining a good crown on the road, or an in-sloped or out-sloped profile, frequent culvert cross drains, rolling dips, lead-off ditches, drop inlets, and other measures that prevent water accumulation. Also major investments are made in drainage crossing structures. Proper culvert sizing is critical, along with good installation, alignment, bedding and compaction, use of headwalls and end sections, protection against plugging and overtopping, etc. Properly designed low-water crossings can offer a cost-effective alternative to culverts in some circumstances, especially on low-volume roads. Finally, bridges are a huge investment and they need adequate hydraulic capacity, protection against a variety of scour problems, bank stabilization, and maintenance.

MS4 Audit Preparation

Do you work for a regulated NPDES Phase I or Phase II MS4 entity? Are EPA and/or your state permitting authority gearing up to audit, evaluate, or re-evaluate local MS4 programs in your area? If so, this webinar will assist you with your audit preparations. Even if an audit is not looming in your immediate future, this webinar will provide helpful tips so that you’re always ready to do your best to demonstrate permit compliance. Examples of how MS4 communities have been audited and what tools they have used to successfully survive those audits will be presented. Audit preparations can also be used to help enhance other MS4 program areas so we will highlight those connections. Key elements of audit preparation include knowing what inspectors are looking for and how MS4 communities are being compared to each other. So take a tip from the Boy Scouts and “Be Prepared”!

Municipal Good Housekeeping Effectiveness Utilizing Facility

Meeting MS4 Program compliance requirements for Good housekeeping & Pollution Prevention can be difficult without a well-executed plan. Conducting Municipal Facility “Hot Spot” Assessments to properly identify facility exposure to pollutant runoff risk is an effective starting point for any regulated MS4. For facilities identified as “Hot Spots”, Facility Runoff Control Plans (FRCP) can one tool used by MS4s to comply with these requirements. J.B. Dixon and Allison Sambol of Felsburg, Holt & Ullevig will discuss the genesis of the FRCP approach, and how it has been successfully implemented in several Midwest large and small MS4s. Kent Holm, Environmental Coordinator with Douglas County, Nebraska, will share his MS4 program’s successful approach to municipal facility good housekeeping by implementing FRCPs in the most populated county in Nebraska.

Organic, Natural: What's the difference?

There are many terms used to describe the different varieties of erosion control products, like organic, natural, weed free, photodegradable and biodegradable. This presentation will define each of these terms and show you were the products should be used.

Polymers for Construction Site Erosion and Sediment Control

This course has been developed to familiarize participants with the concepts of polymers and how they can be used for Erosion and Sediment Control (ESC) on construction sites. The course is intended for developers, consultants, municipalities, landowners or anyone looking to learn about polymers and apply them for ESC. This course consists of six modules that discuss the basic concepts of polymers, soil stabilization with anionic polyacrylamide (PAM), PAM based stormwater clarification applications, additional PAM enhanced sediment controls, PAM assisted pond dredging, and anionic PAM application guidance for urban construction.

Rain Water Harvesting: Applications and Maintenance

As pressure mounts on domestic water supplies and stormwater runoff from impervious surfaces becomes more of a problem, rain water harvesting can lessen pressure on water supplies and reduce stormwater runoff. Rain water harvesting has been used for centuries. In ancient Rome and Byzantium water was stored in huge underground cisterns to help walled citied withstand sieges. In climates with alternating wet and dry seasons water can be stored in cisterns to provide supply in the dry season. Rainwater harvesting can provide economical irrigation water as well as non-potable water for domestic toilet flushing, clothes washing, and car washing if plumbing codes allow.

RAPPS (E&SC) for Oil and Gas Operations

This webinar will focus on reasonable and prudent practices for stabilization of construction activities associated with the oil and gas industry. RAPPS may not be a common acronym for erosion and sediment control practitioners outside of this energy sector’s operations but these “reasonable and prudent practices for stabilization” encompass the world of BMPs for this industry. Important operational, supplemental, and specialty RAPPs will be covered as well as introducing innovative RAPPs that can be used on your next project. RAPPS selection tools will be reviewed that assist the site supervisor in managing the site for protection of sensitive environmental resources and adjacent properties.

Stormwater Low Impact Development Practices • Part 1

This is part 1 of the Stormwater LIDs 2-hour course. Low Impact Development (LID) practices are Best Management Practices (BMPs) developed for managing stormwater runoff from land development sites. LIDs are used (1) to facilitate infiltration of site runoff and (2) to provide treatment of the runoff, thus improving the quality of the runoff entering the local streams and the groundwater. Many LIDs have been developed and are being prescribed by designers and installed by contractors on land development sites. Each has advantages and disadvantages that must be considered if the LID is expected to perform properly. This series will focus on the design and expected function of Bioretention Cells (Rain Gardens) and Green Roofs.
