Whiting Forest of Dow Gardens Installs Permeable Path with 20,000 Square Feet of Porous Pave
Porous Pave Permeable Pavement Makes Wooded Areas Accessible while Protecting the Trees in the Public Garden's Forest
"We had a long list of requirements:
"The permeable pavement replaced bark mulch," said Jonathan Alderson, landscape architect, Jonathan Alderson Landscape Architects, Inc. "To minimize potential damage to the forest, Porous Pave was installed without excavation that could have harmed tree roots."
Four inches of pine needle duff and bark mulch were scraped off to each side of the six-foot-wide path. "After site preparation, Porous Pave was poured and finished at a two-inch depth atop a compacted drainage stone base," said Jeremiah Crivac, site superintendent, Three Rivers Corporation, the general contractor.
The project manager, the landscape crew and an arborist worked in close cooperation. "When tree roots were exposed during site preparation, they were clean cut, kept moist, and covered with mulch and duff," said Alderson. "In the installation of the canopy walk and the permeable path, we had to remove only six trees."
The paving project was completed in August 2018. According to Fred Eddy, Jr., owner's representative and Whiting Forest project manager, Midland Engineering, Ltd., Porous Pave provided additional benefits. "During installation, it was easy to make the material conform to the many curves of the path and to press it right up against the canopy walk decking and limestone walls, forming seamless edges between surfaces," he said. After the Midland, Mich. area received its first snowfall of the season in early November, facility maintenance workers used a power brush to push the snow off the path. Residual melted water permeated down into the Porous Pave rather than freezing and forming ice on the surface. "The path was so clean and dry, I was asked if the surface is heated."
