LID Stormwater Management with

Permeable Pavement Systems

• Advanced Pavement Technology is a Registered Provider with The American Institute of Architects Continuing Education Systems. Credit earned on completion of the program will be reported to CES Records for AIA members. Certificates of Completion for non-AIA members are available on request.

• This program is registered with the AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any manner of handling, using distributing, or dealing in any material or product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

Learning Objectives

1. Learn design applications for LEED

project utilizing a permeable pavement

system.

2. Develop understanding of improved

land planning with use of underground

stormwater storage.

3. Gain knowledge of proper

specifications for construction of a

permeable pavement system.

Water Quantity

Mean weekly pollutant concentration in stormwater runoff from asphalt, paver, and crushed stone driveways. Within each

variable, means followed by the same letter are not significantly different at the 95% confidence level.

Accommodate heavy vehicular loads

Handle vehicular loading better/load transfer

Reduced land costs

Reduce costs of underground piping, sewer lines, etc

Superior in 30-year life cycle costing analysis

Performs in freeze-thaw environments better than asphalt or concrete
