We have provided the following letter with regard to the preliminary geotechnical recommendations of
new permeable paved areas associated with the above noted development.
a. We understand permeable payers are proposed in the area of new driveway and rear patios.
Specific paver detailing should be detailed and constructed per the minimum recommendations of
the Interlocking Concrete Paver Institute and the specific concrete paver manufacturer, including
edge restraints, minimum bedding specifications, base and subgrade requirements, installation
tolerances, and drainage, etc.
b. Where runoff and stormwater is directed over permeable pavements and water is anticipated to
flow through payers into an aggregate base near and adjacent to foundations, detailing shall include
systems to control and to prevent subsurface flow beneath the building. Generally, these systems,
detailed as part of the specific building construction plans, may include the following:
Cut-off walls
Underdrains
Enhanced vapor barriers/waterproof membranes
c. Where an aggregate base is detailed as part of the permeable payers, subgrade below the aggregate
base, should be sloped away from building footprint a minimum of 2% within a distance of 5 feet
and lined with an impervious liner.

Cut-off walls shall be provided across utility and any other trenches that extend to the building
Permeable payers on sloped driveways should be detailed with the edge restraints, concrete band
restraints, benches, cutoff walls and drainage devices, including underdrains where subgrade soils
do not allow for infiltration.
The specific recommendations of the concrete block manufacturer or the ICPI may supersede the
recommendations herein. Specific manufacturer recommendations shall be included in any paver
detailing.
Prior to the finalization of construction drawings, details shall be reviewed by Engineering Design
Group.
If you have any questions with respect to this letter, please do not hesitate to call our office.
