Client: City of Champaign

Clark Dietz is providing preliminary and final design services for various improvements within the Garden Hills residential neighborhood. The scope of work encompasses a range of activities, including drainage, lighting, and roadway improvements.

Key Project Components:

Field survey and data collection, geotechnical survey, drainage and detention basin designs, roadway design, landscape designs, roadway lighting design, traffic signal design, structural designs, cost estimates and technical specifications, bidding services, utility coordination, railroad coordination, public involvement, IDOT coordination, and land acquisition documents.

Lighting Improvements:

A clear street view with a black lamppost, a fire hydrant, and a well-kept sidewalk.

  • Installation of 120 new overhead streetlights with pedestrian globes at intersections and mid-block locations.

  • Reuse of 27 existing streetlights, along with the installation of conduit, conductors, and junction boxes.

Phase 2: Detention Basin and Roadway Reconstruction:

Phase 2 focuses on the construction of a detention basin designed to hold stormwater from a 40-year storm event, along with park-like amenities. Features will include:

  • Walking paths, lighting, benches, water features, native plantings, basketball courts, playground equipment, and other landscape elements.

  • Street Reconstruction: Hedge Road will be reconstructed as a complete street with new storm sewer piping, full concrete street reconstruction, sidewalks, and street lighting.

Phase 3: Storm Sewer Installation and Street Rehabilitation:

Phase 3 involves the installation of large diameter trunk storm sewers to transport stormwater to the Phase 2 detention basin. Work includes:

  • Storm sewers along Paula Drive and Cynthia Drive.

  • Street Reconstruction following a complete street concept, with new storm sewers, sidewalks, and street lighting.

  • A new storm sewer outlet system to alleviate flooding north of the Garden Hills Elementary School.

Detention Basin Design and Park Amenities:

  • Two large detention basins near Norfolk Southern railroad tracks, designed to hold stormwater while avoiding intrusion on railroad property.

  • Soldier-pile retaining walls were designed to provide structural support without anchors in the railroad’s property, ensuring the basins’ required volume is met without encroachment.

Garden Hills Lighting Improvements:

  • The design calls for approximately 120 new streetlights and 27 reused streetlights, along with necessary conduit and electrical hardware.

  • The lighting system will be integrated with the City’s Safety Lighting Energy Efficiency Program (SLEEP), which aims to install yard lights in all homes within the Garden Hills Neighborhood.

Schedule:

  • Phase 2 Design: January 2022 to December 2023; Construction: March 2024 to December 2025.

  • Phase 3 Design: January 2025 to December 2026; Construction: March 2027 to December 2028.

  • Streetlight Design: January 2022 to December 2022; Construction: March 2023 to December 2023.
