Initial Concern
In Norfolk, Virginia, a government client had the opportunity to extend their parking lot, adding 16,500 square feet. Not only did the new area need to meet stormwater storage and nutrient removal regulations, but it also required durability to withstand vehicular traffic. Lastly, the client sought a permeable parking lot that was low maintenance.
Solution
After carefully considering the project requirements and multitude of stormwater solutions, we chose PowerBlock permeable pavers for the parking lot. Because PowerBlock’s pavers interlock and use open joints, they require minimal maintenance in comparison to traditional pavers which must be filled with stone after installation and when they are vacuumed.
Installation
Ferguson Waterworks is more than a premium distributor of stormwater management products, we are a partner. That is why we work alongside our clients and their contractors to ensure they not only get the products they need but also have support through on-site product management and installation. For this project, we worked with our client’s local general contractor and Landsaver Environmental. Landsaver Environmental is a specialty installation contractor with extensive experience in permeable parking lots.
Installing Permeable Pavers
- Preparation for the installation was relatively straightforward. Firstly, the team dug out 19″.
- Then we placed a monofilament geotextile in the hole.
- After that, we topped the geotextile with 14.5″ of stone, consequently, leaving 4.5″ for the blocks.
- Once we leveled and fine-graded the stone, we hand-placed the blocks.
- Finally, we compacted the permeable parking lot. During this process, we laid plywood over the pavers to protect them from damage.
Results
As a result, the new permeable parking lot was aesthetically pleasing, capable of handling large rain events without ponding, and able to meet nutrient removal regulations. Furthermore, the client was pleased with the durability of the parking lot.
In total, the system provides 0.48 cf/sq in stormwater storage.
