Permeable concrete gets a break
After a series of trials and error, Facilities, Engineering and Planning staff may have stumbled upon the secret for its eco-friendly water-permeable concrete: Use the concrete in more lightly-traveled areas. After installing a test strip of concrete in the North Annex lot last year, FE&P workers have learned to mix the concrete off site and that the water-permeable concrete, which can be significantly more expensive than regular concrete, is not interchangeable with regular concrete. The first test patch of permeable concrete was installed in April 2007 on the future site of Duncan College. It has been used in the North Annex Parking Lot, on the walkway between Hanszen College and the Inner Loop, the Oshman Engineering Kitchen, and in front of the Ralph O'Connor House.
