10:14 pm | CDOT RESPONSE TO FLOODING | When Denver7 inquired about Sunday evening’s flooding, especially around I-70, CDOT responded with the following explanation:

Yes, flooding occurred in the Central 70 Project area. The Central 70 Project is still an active construction project. Our drainage network is not yet complete, though it is nearing completion. Once our drainage system is fully complete, the lowered section of I-70 where flooding happened this evening is expected to withstand a 100-year storm event. Every construction project runs the risk of flooding while it’s in an interim phase. To help offset flooding from a system that is not yet complete, our contractor, Kiewit, is able to mobilize to help pump water out. The Central 70 Project is going to conduct a thorough investigation to determine what exactly caused the flooding this evening. Fortunately, as an active construction project, if there are any system failures we are able to go in and remedy any issues that occurred during this event. However, without conducting the investigation, we do not know if there was a system failure. We do know that 46th South Avenue is currently being constructed as a part of our Project between Brighton Boulevard and York Street above I-70, directly above where the flooding in the lowered section occurred. This section is not yet paved creating exceptionally muddy conditions that may have contributed to flooding. This is one area that we are going to be looking at during our investigation.

Safety is always CDOT’s number one priority, we will do what it takes to help prevent something like this from happening again in the future.
