The Bee Branch Creek, formerly known as Couler Creek, is a tributary of the Mississippi River found in Dubuque, Iowa. The creek starts in the west of Dubuque before flowing into the Couler Valley and then into the downtown, flowing through multiple detention basins along the way. Due to the creek's involvement in many disasters, particularly floods, the Bee Branch Creek has become an interest for Dubuque. After restoration projects, the creek has become a daylighted stream with parks and trails along its banks. It has been estimated to have prevented millions of dollars in damages. The Bee Branch has also been involved with numerous ecological projects. Despite being recently daylighted, the Iowa DNR diagnosed the creek with a healthy ecosystem.

The Dubuque Intermodal Transportation Center (DITC) is a bus station located in Dubuque, Iowa. It serves as the new transfer center for Dubuque's bus system, between Jule buses and intercity buses serving Dubuque, and as a transfer point between other modes of land transportation.The center was intended to be the western terminal of the Black Hawk, a Chicago–Rockford–Dubuque Amtrak intercity rail route. The city of Dubuque received an $8 million FTA state of good repair grant in addition to grants from several area institutions to go towards phase 1 of the center's construction. Phase 2 was planned to be funded by a TIGER V grant. That grant application failed, but alternative funding came from several other sources. On April 10, 2014, a new proposal for Amtrak service to terminate in Rockford was announced following the inability of the state of Illinois to reach a deal with the Canadian National Railway for use of their tracks. Due to the new proposal, the train station component of the center was placed on hold until a deal could be reached with the CN. The city of Dubuque broke ground on the rest of the DITC project in May 2014. The center, except for the train station portion, opened on August 17, 2015.

Washington Street and East 22nd Street Historic District is a nationally recognized historic district located in Dubuque, Iowa, United States. It was listed on the National Register of Historic Places in 2015. At the time of its nomination it consisted of 34 resources, which included 29 contributing buildings, and five non-contributing buildings. The focus of this district is a cluster of brick buildings around the intersection of Washington and East 22nd Streets on the north side of Dubuque. Its location west of the former Chicago Great Western Railway and the Chicago, Milwaukee, St. Paul and Pacific Railroad yards led to a large percentage of the residents here to be higher ranking railroad employees. The historic buildings are brick and frame houses, with the exception of one brick storefront/residence. Most of the houses are front or side gabled vernacular structures, and a few that are Italianate or Classical Revival. Couler Creek, which was located behind the houses on the east side of Washington Street, also affected the development of this area. There is no alley behind the houses on the east side of Washington. Flooding was also a major problem in this area until the creek was covered in a stone-arched sewer and continues to flow under ground.
