Pervious Pavers and/or Re-Vegetation
Pervious pavers are a self-draining system that allows rainwater to seep around and through the paved surface, soaking naturally into the ground underneath. Re-vegetation entails replacing impervious surfaces with vegetation.
Removal of impervious surface and replacement with pervious pavers and/or vegetation is commonly done for patios, driveways, and parking lots.
How to Have Impervious Surfaces Replaced by Pervious Pavers and/or Vegetation
Pervious pavers are more expensive than conventional paving but have a longer life expectancy. The total installation cost would depend on site specifics and materials.
Re-vegetation increases the green space on a property and allows for rainwater to soak into the ground naturally.
Benefits of Pervious and Re-Vegetation to the Homeowner
Pervious pavers are more aesthetically pleasing than conventional pavers and provide many advantages for the homeowner. Pervious pavers:
- Come in more colors and shapes than traditional concrete or asphalt
- Can create a longer-lasting surface compared with conventional concrete
- Can reduce basement flooding caused by rain storms that overload the storm sewer
Benefits of Pervious and Re-Vegetation to the District
The District is promoting the replacement of impervious surfaces with pervious and/or vegetation because it improves the health of local streams and waterways by producing substantially less stormwater runoff than non-pervious areas. In addition, pervious pavers and re-vegetation:
- Reduce installation/construction costs of drainage systems (i.e. they eliminate the cost of piping stormwater to an outfall)
- Promote groundwater recharge, increasing both the quantity and quality of water
- Reduce flooding and erosion caused by stormwater runoff
- Promote tree survival by providing air and water to their roots.
Want to remove impervious surfaces in your property and replace them with pervious pavers or vegetation? RiverSmart Homes can help.
DOEE provides homeowners with rebates to retain stormwater runoff on their properties through its Landscaping Rebate Program. Rebates are issued as a direct reimbursement to homeowners at a rate of $10.00 per square foot of impervious surface removed and replaced with pervious pavers and $5.00 per square foot of impervious surface removed and replaced with vegetation. To be eligible, you must be replacing or removing an existing impervious surface (concrete, asphalt, etc.) like a driveway, patio, or parking area. Walkways and small patios are not eligible. The minimum square footage that must be replaced with pervious pavers is 100 square feet and the minimum square footage that must be replaced with vegetation is 200 square feet. For more information visit the Lanscaping Rebate program page.
Pervious Pavers Maintenance
Once your pervious pavers system has been installed, there are some maintenance requirements that should be carried out regularly in order to maintain the efficiency and long lifetime of your new pervious paver system. They include:
- Inspect the site on a regular basis, particularly after heavy rain storms
- Sweep and/or vacuum pervious pavers every three months to prevent dirt from accumulating between the gaps and clogging
- Make sure that the gaps are well filled with coarse gravel, if not, refill them
- Fix or replace damaged pervious pavers
