Construction began this month on the “Gar Building” green infrastructure project located at 414-416 W. Onondaga Street, Syracuse. This project involves converting a run down parking lot previously connected to the combined sewer to a porous asphalt installation with ornamental landscaping. Shown below is the stone infiltration basin and the base course of porous asphalt being installed are shown below.
Construction was completed this month at the JNJ Syracuse restaurant site located at 725 E. Fayette St., Syracuse. The project consisted of porous asphalt to which runoff from the building was directed and added greenspace on site and in the “snow strip” adjoining Forman and E. Fayette Streets.
The Erie-Bruce Green Infrastructure project located at 2112 Erie Boulevard East in Syracuse consisted of porous asphalt, porous pavers, and two bioretention areas. The site is characterized by sloping topography toward the office building, and clayey soils exhibiting low infiltration. The green infrastructure installed not only achieved the Onondaga County Save the Rain program objectives for retention of stormwater on-site, but did so in a manner that actually alleviated the flooding that sometimes occurred in the building related to storm runoff. Construction was completed in the Fall of 2013. Photos are from late Summer 2014.
In August 2014 construction was completed on NSE’s latest green infrastructure project, located at 506 W. Onondaga Street, Syracuse. The project consists of added greenspace and 15,300 sq ft of porous asphalt. The project manages runoff from 17,220 sq ft of impervious surfaces effectively managing over 380,000 gal of stormwater annually.
Construction began this week on Onondaga Commons’ latest Save the Rain green infrastructure project, GIF #09. The project consists of the replacement of 17,200 sq ft of formerly impervious surfaces with 15,300 sq ft of porous asphalt and 1900 sq ft of added greenspace. The project will manage over 380,000 gal of stormwater annually. Photograph is of the porous asphalt base following construction.
The May 2014 Issue of Stormwater Magazine contains an excellent article on page 44 entitled “Exploring New Partners to Green Our Urban Landscapes.” The article describes how incorporating green infrastructure (GI) into site development can yield a return on investment. Some of the examples cited in the article include:
- The visual amenity afforded by a green roof incorporated into an apartment complex in Boylston MA resulted in an increase in rent of between $300 and $500 a month for those units that overlooked the green roof.
- the DECREASE in the amount of frost heave in porous pavements in Chicago, IL when compared with conventional paved surfaces has resulted in a longer lifespan for the installations making porous pavement the lower cost alternative.
- green roofs double the lifespan of conventional roofs thus incurring savings in roof replacement dollars over a 40 year lifespan.
These examples don’t even consider the possible benefits available through various subsidies for such technology nor consider the relative offset in costs where regulations or ordinances would require stormwater management, whether through GI or conventional measures anyway. More detailed information is contained NRDC’s 2013 report “The Green Edge: How Commercial Property Investment in Green Infrastructure Creates Value” discussed in our January 31, 2014 blog post.
On April 7, 2014, the team of Spectra Engineering (Syracuse, New York) and Natural Systems Engineering was notified of award for RFP No. 13-3330-002 – Green Project Design Professional Services for Onondaga County, New York. The project will involve the design of “green streets” under the County’s award-winning “Save the Rain” program.
