CGA Engineers's was awarded the contract to design improvements for he industrial Maintenance Zone 4024 for the City of Tulsa and the Tulsa Metropolitan Utility Authority. This project included street reconstruction, pavement rehabilitation, stormwater design to include a conditional letter of map revision for FEMA, and waterline and sanitary sewer design. The street reconstruction is designed in portions of the project in which the existing street will be completely removed for stormwater construction or in areas in which the existing pavement has completely lost structural capacity or will not drain. Approximately 1,900 feet of street reconstruction will be performed on the project. The streets in this industrial park hadle both passenger vehicles and heavy truck traffic due to the industrial businesses located in the park and reconstruction and rehabilitation were designed to accommodate the truck traffic. The remaining 8,383 feet of the streets in the project are designed to be milled, patched, and overlay.
Previous to the stormwater improvements, several of the buildings located in the industrial park would flood during major storm events. Part of the design for this project included improvements to Mill Creek between S. Joplin Ave. and the Corp of Engineer's detention pond located in the southeast corner of the intersection of E. 13th St. and S. Joplin Ave. s that flooding and erosion would not be a problem. This portion of the creek was outside of the City of Tulsa's right-of-way and the City of Tulsa did not wish to purchase the right-of-way. The selected design was to construct a double barrel 10'X8' bypass structure 480' long that will transport approximately 2/3 of the 100 year storm even directly to the detention facility for this portion of the Mill Creek. The design required special consideration for the bypass structure under the BNSF Railroad and a realignment of the street above the structure. Improvements to stormwater are designed throughout the rest of the project. The waterline throughout the project was designed to be replaced. The design includes approximately 9,437 feet of 6" and 8" waterline. This project allowed CGA Engineers to exhibit their experience in transportation design. Almost 2 miles of streets were either reconstructed or rehabilitated. Major stormwater design which includes a conditional letter of map revision from FEMA is showcased with this project.
