WebPervious Pavement (Examples: Porous Asphalt, Pervious Concrete, Porous Aggregate, Pervious Pavers, Permeable Pavers) • Durable, sustainable materials that create a pervious surface that allows stormwater to infiltrate into the underlying soil. • SCM can include an underlying reservoir to increase retention capacity and infiltration rates.
WebPermeable Pavement will be reimbursed at a rate of up to $14.00 per square foot with a maximum payment of $20,000.00. Permeable pavements are alternative paving surfaces that allow stormwater runoff to filter through voids in the pavement surface into an underlying stone reservoir, where it is temporarily stored and/or infiltrated. WebWater from the reservoir then either percolates into the underlying soil, eventually recharging groundwater, or is collected by a perforated pipe underdrain system and carried to a surface discharge location. An illustration of a vertical section through an asphalt permeable pavement is presented in figure 9.4. Frequency of use

WebHow Does Pervious Concrete Work? Pervious concrete allows the water to flow through it. The permeability of concrete depends upon the percentage of voids in the concrete, and the size of voids. Typically, 15-25% voids are achieved in hardened permeable concrete. The flow rates of pervious concrete are approximately 480 in./hr (200 L/m2/min).
