SCOPE
AWARD AUGUST 2018. In 2016 the City of Kingman retained EPS Group, Inc. (EPS) to explore alternative sewer alignments for the existing sewer main that is currently located within Clack Canyon. This area is extremely rocky, making construction very difficult. This line conveys sewage from the downtown area of Kingman to the Downtown Treatment Plant operated by the City of Kingman. The city does not have any documented easements on private property. However, it is anticipated that the City may obtain a prescriptive easement due to the permissive use of this property for over 30 years. The line is located within the floodplain in all areas and the floodway in a significant portion of the study area. Therefore, the City would like to reroute the sewer so that it is within public right-of-way or defined easements and out the floodway/floodplain. This report presented four alternative alignments for this sewer relocation along with their associated cost estimates. However, the City is open and willing to explore any other possible alignments or methods and encourages new ideas. Currently a predominantly 8-inch and a small section of 10-inch gravity sewer line conveys sewage from the downtown Kingman area to the Downtown Treatment Plant. Construction of these lines occurred in 1970 for the main line in Clack Canyon and 1984 for the connecting Old Trails Line. These lines are generally within private property, with the exception of approximately 2,000 feet of the 1984 line from the Goldroad Ave to the west which is in property owned the City of Kingman. The remainders of the lines are not within any City owned easements. Segments of the line are not accessible by vehicles for repairs or maintenance. The line is also partially located within the BSNF Railway easement/ right-of-way (ROW). The City has obtained license agreements to allow the line with the railroad easement/ROW for a portion of the system but has not obtained an agreement for all city sewer lines. The line is generally within the Floodplain of Clack Canyon creek. It is also located within the Floodway in some segments. The City is electing to solicit the engineering consultant and CMAR at the same time so that both firms can be involved from the very beginning of the design process. The CMAR shall work closely with and be an integral part of this project team during the design and construction phases of the project. bhambrick@cityofkingman.gov
