The City of Carmel engaged Weihe Engineers Landscape Architecture Studio  to design plantings and four new roundabout hardscape features within 1-mile of reconstructed College Avenue roadway from 96th Street to 106th Street. The design includes bioswales within the parkways to accept stormwater runoff that are planted with a mix of native flowering forbs and grasses. Within the corridor four new roundabouts are constructed each with a unique design. The new roundabout at 96th Street provides new gateway signage at the entry into Carmel. The new roundabout at 106th Street was designed to accommodate a public art sculpture designed by a local Indianapolis artist. The project was divided into three separate contracts in which Weihe Engineers had to coordinate the improvements with three different roadway engineering firms.
