Bristol Business Park, Bristol, United Kingdom
According to the National Archive, Bristol Business Park, in Bristol, UK, employs several sustainable urban drainage systems (SUDS) - two of which are permeable pavers (Figure 1) and pavement. SUDS on the site are a detention pond (Figure 2) and a bioswale (Figure 3) between the parking area and the buildings (CABE 2011). The permeable pavers are a product called Hasen Formpave, manufactured in the UK (CABE 2011). This system comes with it’s a proprietary mesh between the different sized gravels, which makes cleaning and maintenance easier - a priority for a successful permeable pavement (CABE 2011).
Landscape Performance Benefits
· Environmental Since this is a man-made hardscape, it's environmental aspects are chiefly related to its function. It does help preserve the life of adjacent plants that might otherwise receive too much storm water.
· Aesthetic These pavers have the appealing look that has been popular for hundreds of years.
· Functional Since runoff into the detention pond during heavy rain periods has been mininal since its installation, it must be functioning as expected.
· Social Paved spaces are usually ideal for outdoor gatherings in a formal setting.
· Educational It can provide data pertaining to watershed reduction related to hardscape area.
· Economical Installation is more expensive than traditional sanded or mortared pavers, due to the trench that must be created beneath it.
· Psychological During heavy rain it removes an obstacle of deep standing puddles or fast moving watersheds within the site.
This project has performed as intended over the last few years that the campus has been in operation. Its success is a direct result of the appropriate initial planning by the developers of the business park. Their choice to reduce storm water drainage has undoubtedly saved them money by reducing maintenance costs.

PUT THESE UNDER THE FIGURES
Figure 1. These pavers are permeable because
the spaces between the pavers are filled with
loose aggregate (CABE 2011).
Figure 2. This is the detention pond found on
the site, which collects water from both the
bioswale and various other sources on the site
Figure 3. This is the bioswale, which catches
runoff of excess storm water from the
permeable pavers and pavement in the parking
area (CABE 2011).
