Purpose
The purpose of this memo is to provide documentation comparing the infiltration rate of Techo-Bloc's Villagio permeable pavers with the typical
infiltration rates of loamy sandy soils found in Saratoga Springs, NY. It also references Section 21.1.1 of the City's Unified Development Ordinance
(UDO), which governs the use of permeable pavement systems for stormwater management.
Applicable UDO Reference
According to UDO Section 21.I.1, permeable pavement is considered an acceptable stormwater management practice if the infiltration rate of the
installed surface meets or exceeds 1.1 inches per hour.
"Permeable pavement shall be considered an acceptable stormwater practice where the infiltration rate of the installed surface meets or exceeds 1.1
inches per hour. "

Performance Comparison
Testing performed in accordance with ASTM C1701 indicates that the Villagio system achieved a surface infiltration rate of 896 inches per hour,
which is approximately 814 times greater than the minimum rate required by the City's UDO (1.1 in/hr).
This level of performance exceeds the threshold for permeable pavement and demonstrates significantly higher infiltration capacity than the loamy
sandy soils commonly found in Saratoga Springs.
Conclusion
Based on Techo-Bloc's technical data and Section 21.I.1 of the UDO, the Villagio permeable paver system not only meets but exceeds the City's
infiltration performance standards for permeable pavement applications. Its measured infiltration rate of 896 in/hr represents an increase of 814 times
over the zoning minimum standard, confirming its suitability as a fully compliant permeable surface within city limits.
Given this exceptional performance, validated by ASTM C1701 testing and surpassing both the City's requirement and local soil infiltration rates, we
respectfully request that the Villagio paver system be recognized as providing 100% permeability coverage calculations. Its demonstrated infiltration
capacity shows that it functions as a fully permeable surface under normal site and rainfall conditions, promoting typical groundwater control.
