Public Works Department City of Decatur 1 Gary K. Anderson Plaia Decatur, IL 62523 RE: Starr Crest Pump Station City Project 2014-32 Dear Matt: Congratulations on obtaining the easements necessary to complete this project. We are very much looking forward to getting this project out to bid and under construction. As you are aware, this project had been shelved for approximately 10 months while the property negotiations were finalized. During this waiting period, Ameren's representative for the project area has changed. Ms. Wyatt is no longer our contact for this project, and the new representative is more receptive to providing equipment and power supply in ways that could result in a reduction of both construction and O&M costs to the City. However, plans and specifications would have to be modified to accommodate such changes; and additional approvals from the Park District and Macon County Highway might be necessary. We estimate that the negotiations with Ameren and affected parties, and the revisions to the project documents will be $6,000.00. This includes the preparation of any additional easement documents, if such become necessary. Additionally, selection of a "green" access drive material for the facility that will meet the aesthetic requirements of the Park District and the performance requirement (supporting a vactor truck) of the Sanitary District has been challenging. Every green paving system seems to have at least one significant drawback, from extremely high installation costs to requiring regular supplemental watering to maintain the turf surface. We believe the design intent for the access drive surface should be revisited. Our estimate for finalizing this element of the project is $4,500.00. In total, we are requesting a contract increase of$10,500.00 for the reasons cited above.
