This structure is a concrete box culvert (CBC) that carries Box Elder Creek and crosses 1-25 just north of the Prospect Street interchange. In 1988, a new CBC was installed to replace the existing two -cell CBC. A four -cell CBC was installed at the request of the City of Ft. Collins for future flows as the downstream drainage was improved. However, until the downstream improvements were made, we agreed to plug two of the cells and leave the flow capacity as it existed at the time. I understand that the City of Ft. Collins has recently updated their flood plans, which is what precipitated the request for CDOT to remove the plugs in the CBC. Since the larger CBC was installed at the City's request and this area is within you planning jurisdiction, we need your concurrence to move forward on the removal of the plugs. Please let me know how the City would like us proceed with this issue. If you or your staff needs any technical information, please contact our Region Hydraulics Engineer, Samer AI-Haj at (970) 350-2140. Sincerely, Karla Harding Region 4 Transportation Director
