SERVICES:

Civil Engineering Site Design of Green Infrastructure

TIMEFRAME:

2008 to 2010

PROJECT DESCRIPTION:

Elements Engineering collaborated with Rundell Ernstberger and EMH&T to prepare the green

infrastructure site design for the urban redevelopment project. Elements also prepared the LEED

documentation for the site credits. The site is located in Downtown Indianapolis at 620 E. Ohio St.

Some of the site features included in the project are: porous pavers, bio-retention and underground

retention storage as well as rain water harvesting from the green roof. The site is a zero stormwater

discharge site. This is because the stormwater system for the site is not connected to the existing combined

sewer system since the soils have the capacity to infiltrate the on-site stormwater. The building has a

green roof and rain water collection cistern. The water from the cistern is used to flush the toilets and any

excess runoff not reused by the cistern overflows into the site stormwater system for infiltration. Native

Plants were used extensively on site to mimic the bio-regions that The Nature Conservancy Serves

throughout the state of Indiana.

The project, certified as LEED Platinum in 2012, was completed in 2010, won the Office of Sustainability

Award (in the Water category) & several categories of The Monumental Affair Award in 2010.
