It is a Portland cement-based, rigid permeable pavement that serves as the surface layer of a stormwater management system, acting as a water filtration system. Beneath the pervious concrete is the second layer of stormwater system, the base rock,which is an open-graded, stone layer that is used for temporary stormwater detention. When rain falls,the pervious concrete allows on-site infiltration of stormwater. It also filters sediments and pollution from stormwater deposited on the pavement surface. Pros: - Pervious concrete has a similar look and feel to concrete but water can easily permeate. - Surface is ADA-compliant and meets EPA stormwater regulations. Cons: - Requires maintenance to keep sediment from accumulating in the pores. Sediment accumulation will impact the permeability of the concrete. - Because this permeable surface is a filter, like any filter it must be cleaned periodically.Cleaning is performed by vacuuming to remove sediments that have accumulated.The frequency of the vacuuming is directly related to the amount of sediment that the surface receives over time. - Sometimes the accumulation of sediment can be too deep for repairs causing it to become impermeable and in need of replacement. Example: // . • t, Permeable Pavers General Description: Permeable pavers are interlocking pavement systems that allow water to flow into layers of aggregate underneath. Pavers are spaced with a gap between units which allows infiltration of water.The pavers can be made into any arrangement and include a wide range of possible material options. The permeable paver section typically includes base stabilization, 6"to 8" of clear open-graded stone, pavers set on top with an open graded stone chip material as jointing infill. Depending on paver type, an edge restraint or concrete curb would be placed on both sides of the driveway. Pros: - Easily made ADA compliant if pavers are less than 1/2-inch apart. - Large variety of paver options and patterns. - Ease of maintenance and repairs. Pavers can be easily removed and reinstated, utility cuts can be completed without affecting the pavement life (no patches), and surface cleaning can be completed with standard vacuuming equipment. Cons: - Could experience damage in freezing temperatures due to water expansion. - Because of the open nature of the surfaces, permeable pavements clog with sediment and debris over time,thereby decreasing the infiltration rate.The rate of decrease depends on sources of deposited sediment. Routine inspections should take place to document surface clogging. Maintenance includes vacuum-sweeping to remove sediment.

'° 1 \\\\ /, Grass Pavers with Plastic Grid General Description: Permeable plastic or concrete grids infilled with grass which facilitate grass growth. Provides a permeable stabilized surface able to withstand residential traffic loading. Plastic grids are made from 100% post-consumer recycled HDPE with a sub-base composed of a base rock with 40%void space. Plastic grid paver installation includes stabilized subgrade geofabric, base rock, plastic grid, and sod. Pros: - The grid reinforces structural integrity of the grass and reduces mud accumulation. - Effectively reduces the heat island effect because the grass fully absorbs and uses the heat instead of reflecting it. - ADA compliant - Natural finish which increases green space Cons: - Subgrade soils with poor permeability require drainage such as perforated pipe or drain with outlet. - Requires regular maintenance such as weeding, mowing, and watering.This is not the best option for drought prone areas. - The grid increases the load bearing capacity of the grass, but this type of surface is not suitable for high-traffic areas. Examples: Permeable Pavers-Gravel or Grass Infill Commercial Paving I TRUEGRID(truegridpaver.com) • 1 � r•� Turf Pavers General Description: Concrete pavers which allow for natura grass to grow between the individual stones. Allows rainwater to filter through the bricks into the soil. Suitable for low-vehicular use areas that need structural strength but benefit from the appearance of green space.Typically include 40-percent open design. Turf pavers usually include an uncompacted subgrade soil, optional geofabric, underdrain (as required), open-graded subbase reservoir, open-graded bedding course, and concrete pavers (which can be infilled with grass or a permeable joint material) Pros: - The grid reinforces structural integrity of the grass and reduces mud accumulation. - Effectively reduces the heat island effect because the grass fully absorbs and uses the heat instead of reflecting it. - ADA compliant - Natural finish which increases green space - Helps with erosion and preserving the soil underneath Cons: - Requires regular maintenance such as weeding, mowing, and watering.This is not the best option for drought prone areas. - The grid increases the load bearing capacity of the grass, but this type of surface is not suitable for high-traffic areas.

Gravel is typically 5/8" or 3/" fill rock. The type and amount of gravel is up to the customer, gravel can be layered on top of the grid to hide the look of the plastic grid. Plastic grid paver installation includes stabilized subgrade geofabric, base rock, plastic grid, and rock. Pros: - Robust surface for parking and driving while also effectively managing stormwater and runoff. - Variety of gravel options depending on desired finish look Cons: - The grids increase stability and prevent most erosion, but the top layer of gravel may need refilling over time. - Similar to the pervious concrete, sediment may accumulate which may impact the filtration of the water.
