+ Reduces or eliminates stormwater detention and retention
ponds, storm sewers, drainage appurtenances and related costs.
+ Increased income potential from increased lot utilization
due to reduced or eliminated stormwater basins.
+ Pavement surface increases curb appeal.
+ Provides 100% permeable surface by runoff passing through
small, open-graded aggregate-filled openings between solid
high-strength, durable concrete pavers.
+ Helps meet local, state and provincial
stormwater drainage design criteria and provides compliance with U.S.
National Pollutant Discharge Elimination System (NPDES) regulations.
+ Meets U.S. Environmental Protection Agency stormwater
performance criteria as a structural best management practice (BMP)
while providing 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 pavers are available in various shapes and
colors from local ICPI members; colored 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 Pavement fits "Green" or sustainable development approaches.
+ Permeable Pavement may be combined with other LID tools such as rain
gardens and vegetated swales.
+ Permeable pavement removes the majority of pollutants
(zinc, copper, phosphorus and suspended sediments) by reducing runoff,
slowing the flow of water and filtering.
+ Permeable Pavement Increases building opportunities
+ Permeable Pavement Reduces demand on the sewer systems.
+ Conserves on-site space: roads, parking, storm water
infiltration and retention all combined into the same space creating
more green space.
+ Permeable Pavement 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 Pavement 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 Pavement construction experience,
inspection and detailing skills.
Performance / Volume Reduction
+ Meets or exceeds runoff local volume reduction standards
via base reservoir storage.
+ Well maintained Permeable Pavement can reduce runoff volumes from
intense rain events typically between 70% and 90%; flooding less likely.
+ Reduced stormwater runoff volumes generate cost savings
in infrastructure sizing and construction.
Peak Flow Reduction
+ Reductions in peak flow may reduce stormwater utility
fees.
+ Permeable pavement can reduce peak flow by as much as
100%, producing runoff rates nearer to predevelopment conditions.
Frequently Asked Questions
Q1. Can Permeable Pavement save money on project
costs? A1.Yes. When total
project costs are factored, Permeable Pavement may be cheaper than other paving
solutions due to multiple benefits from Permeable Pavement. One example is gaining
stormwater management infrastructure with the money spent on paving.
Q2. Can Permeable Pavement be used on clay soils? A2.Yes. Even in clay
soils, Permeable Pavement reduces runoff and helps to capture rainfall events "first
flush" and reduce pollution.
Q3. Can Permeable Pavement be used to replace
every kind of pavement? A3.Permeable Pavement is 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 Pavement have been successfully used even under heavy
commercial loads.
Q4. Will Permeable Pavement enhance property
values? A4.The data from
installed PICP projects indicates that Permeable Pavement meets multiple criteria for
project success including enhancing property values.
