It will be necessary to construct an oversized 12" sanitary sewer through the North Sunset Ridge Subdivision to serve the land to the west that is designated for future growth in Ames Growth Plan 2040; and, WHEREAS, the contract rezoning agreement includes a cost sharing provision for this sewer where the developer paid for the project design and will pay for a proportionate share of the construction based upon the equivalent costs of a standard 8" sanitary sewer. The remaining construction expenses are considered"oversizing" costs for the City and will be financed through by American Rescue Plan Act(ARPA) funds; and, WHEREAS, the project will consist of the installation of 3,500 linear feet of 12" sanitary main. Due to parts of the sanitary sewer line (approx. 340 linear feet) being placed on a parcel in the county,staff has been working with Story County to obtain a conditional use permit as required by the County's land development (zoning) codes. Following receipt of construction bids, Ames and Story County staff walked the site again on December 28, 2022, to determine tree removal needs if the sewer were to be directional drilled; and, WHEREAS, Story County has issued the conditional use permit with no tree mitigation requirement due to an "insignificant modifications" determination. This determination is a result of less than 15% of the natural area to be impacted. Bid Alternate A was included in the plans and specifications for directional drilling under the majority of the trees, however, some trees will be selectively removed to access the main trunk sewer for manhole placement at the connection point; and, WHEREAS, one bid submitted was declared nonresponsive, because the price for Alternate A was not included in the proposal form. Staff reviewed the bids and determined that apparent low bid is acceptable, although the bid exceeds the Engineer's Estimate, the bid is consistent with construction cost increases experienced with other projects in recent months.
