The green renovation of the Rosamond Gifford Zoo parking lots contribute significantly to the CSO reduction efforts of Onondaga County. The parking lots have generated a tremendous amount of runoff in the past, a problem that will be alleviated with the implementation of several new green infrastructure features. The main technologies incorporated in the design are areas of porous pavement within the parking lots and multiple large subsurface infiltration beds. Working in combination with bioretention areas vegetated with native plants, the green infrastructure technologies of this project capture approximately 4.2 million gallons of stormwater annually, making it one of the largest projects to date in the Save the Rain program.
This project was the fourth of five green infrastructure projects around and within the Rosamond Gifford Zoo. The first project included a cistern and a section of porous pavement installed in the courtyard along with a rain garden adjacent to the primate exhibit in 2010. The second was the green roof on the new elephant barn in 2011. The third was a series of bioretention areas at the zoo entrance on Wilbur Ave, adjacent to Conservation Place, constructed over the course of 2011-2012. The fifth Save the Rain project at the zoo, constructed in 2013, created a stormwater wetland and recirculation system throughout the wetland and existing duck and swan ponds and add a stormwater cistern at the bear exhibit. These five projects combined capture nearly 6 million gallons of stormwater annually.
