The reconstruction of Jackson Street was part of the City’s Capital Improvement Plan for several years. The reconstruction started several years ago at 36th Street with work extending south since then. Recently the City desired to extend the reconstruction from 18th Street to south of 14th Street.
DGR Engineering was selected as the most qualified firm to provide the design services for this project. This project included new utilities (sanitary sewer, storm sewer and water main), new sidewalks, paving and traffic signals. An HMA street option was also presented in the plans which included a granular base and subdrains. Improvements to W. 14th Street extended one-half block west.
A traffic study was completed by our traffic engineer subconsultant, Snyder and Associates, in the area of W. 14th Street and Jackson Street. Improvements to the northeast corner radius of W. 14th and Jackson Street was also part of the plan. The project was completed in three (3) stages with up to two (2) phases in a stage.
Project details including access during construction were discussed with local businesses. DGR was involved in all aspects of survey, design and letting of the project as well as limited construction administration.

DGR Engineering (DGR) worked with the City and the project architect for all aspects of the project including topographic survey, site design, construction survey, construction observation and administration.

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.
Wastewater Treatment Facility
MBBR technology was chosen based on cost, operational flexibility and most importantly, limited land availability.
DGR employed a Geographic Information System (GIS) in conjunction with the U.S. Army Corps of Engineers to first determine the 100-year flood elevations and delineate the floodway boundaries.
Due to concerns with the age and condition of the structures, along with safety clearances to energized equipment and conductors, a project was undertaken to replace the old infrastructure with new underground lines and associated padmount equipment.
