Background/Discussion
West Graham Avenue is in need of reconstruction. The project extends 1,540 feet in length, from High Street to Fairmount Avenue. This street segment is a boulevard with a 30-foot wide raised median with trees, located within an existing right-of-way of 100-feet. West Graham extends east – west with a single lane of travel in each direction and parallel parking allowed along the outside curbs in most locations. It is a residential area with houses fronting the street, with the majority having individual driveways. West Graham is a collector roadway that serves as a connection to East Graham and S. 1st Street.
The project will include new street pavement and sidewalks, drainage improvements, and new sanitary sewers. The raised median will be removed and a 44 foot wide roadway will be constructed which allows for parking on both sides of the street. The intersection of West Graham and Marion Avenue will be a roundabout. The project will be let by the Iowa DOT.
The Council Bluffs Water Works is planning to reconstruct their water line as part of this project. The proposed agreement allows for the water main work to be performed under Project PW25-10 and provides for 100% reimbursement from the Council Bluffs Water Works for the costs associated with the water main.
The design for the water line improvements was completed by Water Works’ engineer, HGM Associates. The engineer’s estimate for the waterline reconstruction is $503,700.
This Federal-aid project was included in the FY25 CIP. The estimated construction cost is $3,845,185, which includes $503,700 in water main and $437,000 in sanitary sewer. The sanitary sewer will be funded with Local Option Sales Tax funds. Roadway and storm sewer costs are estimated to be $2,905,000. STBG funds will be used up to $2,324,000 for the roadway and storm sewer construction; the remaining amount including engineering will be paid with Local Option Sales Tax funds.
