Street Reconstruction

This project involved the reconstruction of approximately 8,500 linear feet of residential street including replacement of all utilities located between Hamilton Boulevard and Grandview Park and between W. 23rd Street and the Valley Drive.

The project was phased over a three-year timeline due to the steep topography, curved streets, narrow right of way, and lack of side street and alley access.

The project also included adding sidewalk along one side of the street and colored and stenciled concrete at crosswalks. A stamped and stained emblem chosen by the Heights Association (created as a result of this project), was imprinted into the driveway of each residence along with the year the house was built.

The project was coordinated with private utility companies (MidAmerican, Qwest and Cable One) to relocate private utilities prior to street reconstruction using directional bore in a City obtained permanent utility easement.

All overhead utilities are to be installed underground. In order to involve the residents in the design process and to prepare them for construction, the area was separated into four (4) zones with lead and alternate representatives identified to be involved in the design process. A total of four (4) public meetings were held for the project to discuss the project schedule, design features, construction impacts, etc.

Sanitary Sewer Rehabilitation

The project was bid and came in under budget. Manhole lids were raised to provide better access in some areas, and rehabilitation of the sewer system was completed to give another 50 years of life to the City’s much-needed infrastructure.
