Sanitary Sewer Collection System Evaluation & Rehabilitation
Marengo, Iowa

In 2009, the Iowa Department of Natural Resources requested that the City prepare a Plan of Action to address non-compliance issues related to inflow and infiltration. Veenstra & Kimm, Inc. worked with the City to prepare a plan of action to revise wet weather flow processing at the treatment facility and to investigate I&I. The City also requested that additional improvements be delayed until the City received their new discharge permit. IDNR accepted the plan of action and Veenstra & Kimm, Inc. worked with local contractors to coordinate the necessary improvements.

In September of 2011, the United States Environmental Protection Agency issued a compliance order to the City to upgrade their treatment facility to handle the I&I or construct collection system improvements to reduce I&I. The City contracted with Veenstra & Kimm, Inc. to evaluate the collection system and prepare a report to recommend improvements needed to reduce I&I. Following a thorough investigation of the system including review of CCTV video, manhole inspections, review of backup complaints, and discussions with City staff, Veenstra & Kimm, Inc. worked with USEPA, IDNR, SRF and the local Council of Governments to prepare a phased program to rehabilitate the sewer system. Rehabilitation work will include cured in place lining of sewers and manholes, reconstruction of manholes, point repairs, casting replacement, chimney seals, and manhole grouting.

The City applied for CDBG funding and an SRF loan for the first phase of construction. The City was awarded a $600,000 CDBG grant in June of 2013. The project plans and specifications were prepared following award of the CDBG grant and bids were received in January of 2014. The project cost for Phase 1 is $1,030,000. The City applied for CDBG funding for Phase 2 sewer rehabilitation work and was awarded a $600,000 CDBG Grant in 2014. Phase 2 construction cost was $1,060,000. The City applied for CDBG funding for Phase 3 and was recently notified that they have been approved for a third CDBG Grant in the amount of $600,000.


120 th Street Reconstruction
Shueyville, Iowa

The 120th Street Reconstruction Project was a jointly funded project between the City of Shueyville and Johnson County. The roadway carries over 5,000 vehicles per day and is a key access to Interstate 380 for several communities and rural subdivisions as well as Lake MacBride recreational area.

Reconstruction efforts required significant public notification and input. Over 30 easements and five right-of-way acquisitions were required to complete the project. Existing ditches were filled on a substantial portion of the project and grading was performed on existing properties. Several retaining walls were required to limit disturbance to adjacent properties. Driveway approaches were reconstructed and sidewalks and trails were added along the urban section.

The project began in April of 2012 and was substantially completed in November of 2012. Project construction and staging had to be coordinated with several holidays including Memorial Day, Fourth of July, and Labor Day due to holiday traffic accessing Lake MacBride for recreational purposes. 120th Street is also a critical route for emergency response vehicles as well as bus traffic for the College Community School District. Changes in detours impacted bus routes and required regular communication between the school district and the project manager.

The project was constructed in 18 phases to maintain access to residences and provide one way traffic into Shueyville. Coordination was required with Johnson County, Linn County, and IDOT to provide detour routes for traffic. The public was informed of changes to detours and updated on construction progress by accessing a project website set-up and maintained by Veenstra & Kimm, Inc. The website also contained a comment section where residents could post comments or request information on the project.

The planning, funding arrangements, design, construction administration, and other project services were provided by our Coralville office.
