Civil Engineering Site Design of Green Infrastructure

Fall 2009 to Spring 2011

Elements Engineering prepared the civil engineering site design for the sustainable site features.  The project is located on the near eastside of Downtown Indianapolis.  The urban redevelopment project is largely residential and is located within a combined sewer area.  Elements was a subconsultant to RW Armstrong and worked closely with Eden Collaborative to complete the project for the City of Indianapolis DMD as well as the Indy-East Asset Development (IAD) community Development Corporation.
Some of the features included in the project are:  three Green Alleys paved with Pervious Concrete;  Rain Gardens along 10th Street and Jefferson Avenue which utilize Native Plants.  Elements collaborated with the design and construction team to create a design that reflects the master plan for the St. Clair Place community.  Elements was also on the Master Plan team which collaborated with IAD and the community to set the parameters for the project.

The project was completed before the national football event held in Indianapolis in 2012.
