Sanitary District Project 20 – Thompson Ditch/Poplar Street Relief Interceptor

HWC worked with the Terre Haute Sanitary District to complete this $4.5 million relief interceptor project.

The constructed interceptor in the Thompson Ditch drainage way now intercepts flow from Seelyville and conveys them to the Southside Lift Station via 36”, 48”, and 60” interceptors. The interceptor also collects flow from a combination sewer and force main constructed on Poplar Street to relieve overburdened sewers on Poplar Street.

Finally, an existing regional lift station near the intersection of Poplar Street and SR 46 was upgraded and replaced.

The project involved significant road reconstruction, traffic planning, land acquisition, and public awareness.

City Hall

HWC worked with studioAXIS and the City of West Lafayette, Indiana to provide survey and site design for the rehabilitation of the existing West Lafayette City Hall site. The existing site had a building that was salvaged and completely remodeled to preserve the existing façade.

The previous site design was revised, and a new parking lot and utilities were built. The east entrance of the building was improved to create an exterior plaza, new exterior spaces, and our design helped preserve the character of the existing building. A future expansion of the streetscape is planned for the west side of the building.

The existing site contained a rain garden that was improved and drainage for the site is now collected before release from the site. The City installed a new water main along the north side of the site and provided new utility connections for all utilities. HWC also worked closely with City officials to develop a landscaping plan that enhanced the site and met all required ordinances.

Icon on Main

HWC has provided, and is continuing to provide, site and survey services for the Icon on Main mixed-use development located at the southeast corner of the busy intersection of Old Meridian and Main Street: the gateway into downtown Carmel, Indiana.

Icon on Main is approximately a $75.4 million project with a five-story building, including 22 residential units, 266 luxury apartments, 9,720 SF of office/commercial/retail space, a 585-space public parking garage, and a public plaza. The project also includes two amenity areas (27,300 SF) that required ramps and retaining walls to ensure ADA slopes were provided in every direction within those areas, and the site offers pedestrian and bicycle connectivity to other amenities in the area. The entire development encompasses ± 138,000 SF and 5.6 acres.

The overall site included grading to balance out the earthwork, storm sewer infrastructure, and an underground detention system being utilized underneath the proposed parking garage. The project also included utility service lines to the building along with a water main relocation and a sanitary sewer main extension. The Tax Increment Financing (TIF) from this development will go toward funding the free public parking garage.

HWC has worked closely with the developer, Edward & Sons, and the City of Carmel Redevelopment Commission on the design throughout the entire process. Construction began in August 2023, including demolition, environmental mitigation, and the installation of underground utilities and is expected to be completed in 2026.
