Description: The capability to simultaneously maintain water quality, reduce flooding, increase base flow, and preserve valuable parking areas for the property owner is not easily obtained with other water quality or flood mitigation alternatives. Pervious concrete provides a unique leadership opportunity for stewardship in context-sensitive construction and Low-Impact Development (LID). This document describes the fundamental hydrologic behavior of pervious concrete pavement systems and demonstrates basic design methodologies appropriate for a variety of sites and circumstances.
This 72-page publication provides an overview and discussion of techniques which can be used for hydrological design, considering the inter-relationship between runoff characteristics, material characteristics, and site geometry. It also provides guidelines for the preliminary selection of appropriate pervious concrete characteristics for specific applications and environments. This publication will assist:
1. Civil engineers, landscape architects, and other design professionals for guidance in the selection and design of an appropriate pervious concrete pavement system,
2. Permit granting agencies in the review and acceptance of proposed pervious concrete pavement systems; and
3. Developers and owners interested in a more complete technical review of pervious concrete pavement systems.
A properly designed pervious concrete pavement system can reduce the environmental impact
often associated with development. Pervious concrete pavement systems can also be used to
improve the environmental performance of existing sites without compromising the business
value of a property by replacing existing conventional pavements. The capability to simultaneously maintain water quality, reduce flooding, increase base flow, and preserve valuable parking areas for the property owner, especially in retrofit applications, are capabilities not easily obtained with other water quality or flood mitigation alternatives.
This document describes the fundamental hydrologic behavior of pervious concrete pavement
systems and demonstrates basic design methodologies appropriate for a variety of sites and
circumstances. This document also briefly discusses limitations of these methodologies.
