The City of Warren retained Hubbell, Roth & Clark, Inc. (HRC) to assemble a comprehensive Master Plan for the infrastructure needs within the new Warren "City Center" complex. The Master Plan addressed all aspects of the proposed and existing infrastructure within the City Center complex; HRC analyzed the sanitary sewer systems, storm sewer systems, water supply systems, and the roadway network.

The analysis of the utilities, which included the sanitary, storm and water supply systems, included a review of the existing systems within the vicinity of the City Center complex. A determination of available capacities within the existing systems and a determination of future capacities required to adequately serve a fully developed condition was evaluated. Based on the analysis, a utility network to serve the new City Center was recommended. HRC was a member of the DDA Administrative Team during the layout of the roadway network. The team worked closely during this process to assure that the street system was compatible with new development as well as current land uses. Issues considered during roadway layout were location, alignment, right-of-way width, lane width, on-street parking layout, pavement type, street lighting, sidewalk width and construction staging.

HRC summarized the results of the comprehensive Master Plan study in a technical report. The total cost to construct the infrastructure required for the 5 phases was estimated to be $13,500,000.

Upon completion of the Master Plan, HRC began design for Phases I and II of the project which included the work within City owned property that was constructed in conjunction with the new City Hall, Library, Parking Deck and City Square Park. Included in the project are 9,200 feet of 12"-60" storm sewer, 7,500 feet of 8"-12" sanitary sewer, 8,325 feet of 8"-12" watermain and 8,300 feet of new concrete roadway with on-street parking bumpouts.

Construction of Phases I and II began in September 2004 and was completed during the 2005 construction season. HRC provided Construction Administration services for the City and DDA, including an on-site Resident Project Engineer, construction observation, construction layout and preparation of pay estimates, etc. To update the City regarding the schedule and construction related issues, weekly progress meetings were held at the job site.
