Hydrologic Design of Pervious Concrete
Abstract
Pervious concrete can be an important part of context-sensitive construction and low-impact development (LID), used to improve water quality by capturing the “first flush” of surface runoff, reducing temperature rise in receiving waters, increasing base flow, and reducing flooding potential by creating short term storage detention of rainfall. In order to fully utilize these benefits, the hydrological behavior of the pervious concrete system must be assessed. The hydrological performance is usually a key parameter in decisions to use this material as a best management practice (BMP) for storm water management. This publication provides an overview of design techniques for determining hydrological performance and provides an example spreadsheet for analysis. The critical inter-relationships between precipitation potential, pervious concrete system characteristics and site geometry are considered. This publication is intended to assist:
w Civil engineers, landscape architects, and other design professionals in the design of an appropriate pervious concrete pavement system, including providing notes on limitations and additional resources. w Permit-granting agencies in the review and acceptance of proposed pervious concrete pavement systems with either active or passive mitigation strategies. w Developers and owners interested in a more complete technical understanding of pervious concrete pavement systems.
