Run<strong>of</strong>f Reduction Control Measure Fact SheetPorous PavementModular Block PavementPorous modular block pavement (Figure PP-2) consists <strong>of</strong> concrete blocks with 20% or more open area,which is filled with sand or sandy loam turf. The units are installed over a gravel subgrade. This type <strong>of</strong>pavement is best suited for areas with low traffic loadings and seasonal/infrequent vehicle traffic, such ascourtyards, driveways, overflow parking areas, and maintenance access roads. Check with the local fireauthority about whether this option is acceptable for fire access lanes. One benefit is that it does notrequire utility cuts; instead the blocks can be taken out and replaced after utilities have been installed.Refer to Table PP-1 for design criteria for this type <strong>of</strong> porous pavement.Other Names: Open-celled unit pavers, turf block, Grasscrete Photo: M&C Pavers, Florida<strong>Stormwater</strong> <strong>Quality</strong> <strong>Design</strong> <strong>Manual</strong> for the <strong>Sacramento</strong> and South Placer RegionsPP-6 <strong>May</strong> <strong>2007</strong>
