Sites were either constructed of permeable interlocking concrete pavers (2), porous concrete (1), or concrete grid pavers (1). One site of each pavement type was monitored for runoff reduction for periods ranging from 10 to 26 months. Measured runoff depths from rainfall events over 50 mm were used to determine permeable pavement equivalent curve numbers for the sites, which ranged from 45 to 85. Only the two permeable interlocking concrete pavement (PICP) sites were monitored for water quality. Runoff and exfiltrate samples were intended to be collected, in addition to runoff monitoring, from the Swansboro PICP site. However, no runoff was produced during this study from the Swansboro PICP site for rainfall events up to 88 mm . From exfiltrate concentrations, nutrient retention was estimated to be 3.4 and 0.4 kg∕ha∕...}, number={6}, journal={Journal of Irrigation and Drainage Engineering}, author={Bean, E. Z. and Hunt, W.

Two surface infiltration tests pre- and postmaintenance were performed on 15 concrete grid paver lots filled with sand. Maintenance was simulated by removing the top layer of residual material 13-19 mm. Simulated maintenance significantly p0.007 improved the surface infiltration rate. The median site surface infiltration rate increased from 4.9 cm/h for existing conditions to 8.6 cm/h after simulated maintenance. Fourteen permeable interlocking concrete pavers PICP and eleven porous concrete PC sites were also tested. PICP and PC sites built in close proximity to disturbed soil areas had surface infiltration rates significantly p0.0014 and p0.0074, respectively less than stable landscape sites. Median PICP surface infiltration rates of each condition were 80 cm/h and 2,000 cm/h, respectively. Median PC surface infiltration rates with and without fines were 13 cm/h and 4,000 cm/h, respectively. This study showed that: 1 the location of permeable pavements; and 2 maintenance of permeable pavements were critical to maintaining high surface infiltration rates.}, number={3}, journal={Journal of Irrigation and Drainage Engineering}, author={Bean, E.
