This two part webinar will address the guideline published by the American Society of Civil Engineers. The first part will address the design, construction and maintenance of permeable pavement. The use of permeable pavements for stormwater management is gaining rapid acceptance across North America. While permeable pavements have been around for a long-time, poor performance is not unusual. The design of permeable pavements differ from other traditional pavement systems in that both structural and hydrologic considerations impact the system depth, one of three different infiltration approaches can be used based on site and subgrade conditions, and unique elements are included over sloped subgrades. This webinar highlights best practices for the design, construction and long-term maintenance of asphalt, concrete and interlocking concrete permeable pavements. Lessons learned from the preparation of a new ASCE Standard for the Design of Permeable Pavements are presented.

The second part of this event will address the management practices for control of erosion and sediment from construction activities. This will be an overview of a recently published Standard establishing guidelines for controlling accelerated erosion caused by human activities at construction sites. This Standard provides tools to ensure the discharge of sediment does not significantly increase at a construction site compared with preconstruction conditions.

Presented by David Hein, P.Eng.

David Hein, P.Eng., is a principal pavement engineer with Applied Research Associates (ARA). ARA is a science and engineering firm specializing in practical solutions to everyday problems. Mr. Hein has been extensively involved in the use of permeable pavement infrastructure and chairs the ASCE Committee that developed a structural and hydrological design standard for permeable pavements. He has lectured extensively on the design, construction and maintenance of permeable pavements.

Presented by Dennis Richards, P.E., D.WRE, F.EWRI, F.ASCE

Dennis L. Richards is an engineering consultant in Phoenix, Arizona with a focus in hydraulic and sedimentation engineering. His experience encompasses planning, analysis, design, and construction of stormwater and flood control projects. Dennis has served as Project Principal and/or Project Manager for numerous projects involving hydraulic and sediment transport analyses, floodplain delineation, channel and bridge scour analyses, stream stability, levee and/or bank protection design, and grade-control structure design. He has conducted investigations to evaluate channel stability and impacts to structures due to in-stream sand and gravel mining. Dennis has prepared design guidelines, procedures, and manuals; developed and presented numerous training courses on hydraulic design, scour analysis, stormwater management, and floodplain issues; and published a number of technical papers. He has provided technical support for litigation cases concerning drainage and flooding problems, channel and bank erosion, sedimentation, and floodplain/floodway issues.
