Birds Eye View of New Green Roof at Zip Networks!

As seen from a passing drone, shown is the new vegetated roof at Zip Networks, 100 Wilkinson Street, Syracuse.  The green roof is an extensive green roof planted with sedum.  Construction was performed by Shaffer Building Services (Syracuse, New York) based on the design of Natural Systems Engineering.   The roof looks brown due to the erosion control mat, but will be green by the end of the season!  The project was funded by Onondaga County’s award-winning Save the Rain program.

First 2015 Save the Rain Project Nearing Completion!

Work is almost complete on the porous asphalt lot at Crest Acura.  The permeable base is shown below.  The project was designed by Natural Systems Engineering and construction is being performed by Rich & Gardner Construction Company (Syracuse, New York).  In addition to managing incident precipitation to the ~15,000 sq ft lot, the project will also infiltrate runoff from the adjoining Crest Acura showroom and service areas.  A total of 1.5 million gallons of stormwater will be managed annually.

On June 1-2, 2015, following placement of the permeable base course shown below, NSE measured the site-wide infiltration rate through the roof sump/overflow catch basin.  Following the June 1 rain event, the site exhibited an infiltration rate of 0.35 in/hr.  Based on this rate, the infiltration basin will completely dewater in roughly 10 hours assuming no additional rainwater input.
