Residential, commercial and municipal permeable pavements can all contribute toward reduced stormwater runoff and pollutants. Detail drawings and a guide specification for editing to project conditions provide means and methods for constructing these innovative pavements.
Permeable interlocking concrete pavement (PICP) is comprised of a layer of concrete pavers separated by joints filled with small stones. Water enters joints between solid concrete pavers and flows through an "open-graded" base, i.e. crushed stone layers with no small or fine particles. The void spaces among the crushed stones store water and infiltrate it back into the soil subgrade. The stones in the joints provide 100% surface permeability and the base filters stormwater and reduces pollutants.

CASE STUDIES AND ARTICLES
Permeable Pavement Fact Sheets - Created by the Low Impact Development Center and ICPI, are aimed at design professionals, developers, municipalities and schools/universities. Each 4-page, color brochure introduces PICP, advantages and how each meets the needs of each audience.

Tech Spec 18: Construction of Permeable Interlocking Concrete Pavement Systems
Summarizes permeable interlocking concrete pavement (PICP) and provides guidance on best construction practices
Model Stormwater Ordinance for Permeable Interlocking Concrete Pavements
Gives local governments a head start in the development of a stormwater ordinance that includes PICP. The ordinance should be adjusted to local conditions.
