+ Provides 100% permeable pavers surface by runoff passing through
small, open graded aggregate filled openings between solid
high-strength, durable concrete pavers.
+ Helps meet local, state and provincial
storm water drainage design criteria and provides compliance with U.S.
National Pollutant Discharge Elimination System (NPDES) regulations.
+ Meets U.S. Environmental Protection Agency storm water
performance criteria as a structural best management practice (BMP)
while providing permeable pavers for parking, road and pedestrian surfaces.
+ LEED® point eligible for Sustainable Sites, Water
Efficiency, Materials & Resources and/or Innovative Design;
Contributes to Green Globe points.
+ May be used on sloped sites with proper design.
+ ADA compliant.
+ Concrete permeable pavers are available in various shapes and
colors from local unit paver manufacturer PICP members; colored Permeable pavers mark lanes and parking
spaces.
+ Simplifies surface and subsurface repairs by reinstating
the same paving units; no unsightly patches or weakened pavement from
utility cuts.
Environmental Quality Improvement
+ Permeable Systems fit "Green" or sustainable development approaches.
+ Permeable Pavers may be combined with other LID tools such as rain
gardens and vegetated swales.
+ Permeable paving systems removes the majority of pollutants
(zinc, copper, phosphorus and suspended sediments) by reducing runoff,
slowing the flow of water and filtering.
+ Permeable Pavers Increases building opportunities
+ Pervious Pavement Reduces demand on the storm water management systems.
+ Conserves on-site space: roads, parking, storm water
infiltration and retention all combined into the same space creating
more green space.
+ Permeables Preserves wooded areas that would otherwise be cleared
for storm water detention or retention ponds.
+ Increases site infiltration that helps maintain
predevelopment runoff volumes, peak flows and watershed timing
+ Promotes tree survival and growth.
+ Contributes to urban heat island reduction through
evaporation and reflective, light colored concrete pavers.
+ Highly visible, cost-effective exemplary demonstration of
a cornerstone LID technique for public and private development.
Application Opportunities
+ Urban: Office plazas, sidewalk replacement, street tree
planting areas, parking lots, parks and outdoor seating areas.
+ Suburban: Permeable Pavers can be used in parking lots, parks, driveways, parking bays on
roadways, subdivision roads and sidewalks.
+ Redevelopment Sites: Parking areas, plazas and public
spaces and sidewalks.
Construction Checklist
+ No compaction of soil sub-grade - excavate and trim
native soil.
+ Geotextile, drainage pipes and overflow vary
with design.
+ Ensure no sediment and mud on aggregates from
equipment.
+ Install and compact aggregate sub-base and base
with typical paving equipment
+ Specialty equipment used for screeding bedding
layer and for mechanical permeable pavers installation
+ Concrete pavers, non-frozen bedding, and
base/sub-base installable in freezing temperatures over non-frozen soil
sub-grade.
+ Paver joints filled with open-graded aggregate and
compacted.
+ No curing time - ready to use upon installation;
modular construction allows for project phasing.
+ Specify ICPI certified (Creative Hardscape
Company, Inc.) installers with Permeable Paving construction experience,
inspection and detailing skills.
Performance / Volume Reduction
+ Meets or exceeds runoff local volume reduction standards
via base reservoir storage.
+ Well maintained Permeable Pavers can reduce storm water management runoff volumes from
intense rain events typically between 70% and 90% of flooding is less likely.
+ Reduced storm water runoff volumes generate cost savings
in infrastructure sizing and construction.
Peak Flow Reduction
+ Reductions in peak flow may reduce storm water utility
fees.
+ Permeables can reduce peak flow by as much as
100%, producing runoff rates nearer to predevelopment conditions.
Frequently Asked Questions
Q1. Can Permeable Pavers save money on project
costs? A1.Yes. When total
project costs are factored, Permeable Paving may be cheaper than other paving
solutions due to multiple benefits from Permeable Pavers. One example is gaining
storm water management infrastructure with the money spent on paving.
Q2. Can Permeables be used on clay soils? A2.Yes. Even in clay
soils, Permeables reduces storm water management runoff and helps to capture rainfall events "first
flush" and reduce pollution.
Q3. Can Permeable Pavers be used to replace
every kind of pavement? A3.Permeables are best suited
for use in areas of low speed traffic such as parking lots, residential
streets, driveways, patios, plazas, sidewalks and parking lanes.
Nevertheless, Permeable systems have been successfully used even under heavy
commercial loads.
Q4. Will Permeable Paving enhance property
values? A4.The data from
installed PICP projects indicates that Permeable Interlocking Concrete Pavement meets multiple criteria for
project success including enhancing property values.
