The option to connect to watermain will be discussed in detail in both the letter that will be mailed to residents inviting them to the neighborhood information meeting, as well as at the neighborhood meeting itself. As previously noted, watermain can be incorporated into the bidding documents as either a base bid or an alternate bid item should Council wish to see what the actual cost would be to construct watermain during this projectprior to making a decision. 4.4Sanitary Sewer Improvements Trunksanitary sewer improvements are not currently proposed with this project, but could be constructed if sufficient interest is voiced by residents wishingto connect to City sewer to address concerns about failing septic systems,or if they simply wish to take advantage of the cost savings that can be realized by connecting to City utilities during street reconstruction projects. The option to connect to sanitary sewer will be discussed in detail both in the informational letter tobe mailed to residents inviting them to the neighborhood information meeting, as well as at the neighborhood meeting itself. As previously noted, sanitary sewer can be incorporated into the bidding documents as either a base bid or an alternate bid item should Council wish to seewhat the actual cost would be to construct sanitary sewer during this projectprior to making a decision. 4.5Construction Methods The existing pavement will be reconstructed by first removing the existing bituminous curb, pavement,and class 5 aggregate base. Then, the existing subgrade will be corrected by excavating 3 feet of subgrade soils and replacing them with 3 feet of select granular borrow. However, if during construction it is determined that the subgrade soils are suitable enough to allow one or both street segments to be constructed by scarifying 1 or more feet of subgrade soils, this method will then be utilized with concurrence from NTI or their representative. Paving will be completed in two separate lifts upon acceptance of the aggregate basegrading. It is anticipated that the final lift of the bituminous wear course willbe placed on both streetsin the same yearas the bituminous base course, as long as the weather cooperates and nodeep utilities work was completed under the streets.Ifdeep utilitiesareinstalled under any streets,the wear course willthen be left off until the following year to allow the soils under the streetsufficient time to settle. If utilities construction is completed, manhole and catch basin castingswill be removed and the structures will be covered with metal plates to prevent materials from dropping into the facilities.
