Mayor and City Council March 18, 1.987 Page Two a new flared -end section in the event the existing piece is damaged during removal. Staff had determined that the Public Works Department has the time and capability to install the additional fill that would be required over the pipe. Therefore, the prices received do not reflect this work. The Price received from Park Construction is $ Inc.'s 4,600.00. Lake Court Utility Contracting, price was $5,950.00. The high cost of these quotes led Staff to examine another possibility. If the City were to buy the pipe and have it delivered, our cost would be $2,150.40. If a new flare -end section was needed, the cost would be $203.15. To install the pipe, H.B.H. Contracting, who has worked with the City previously, has offered to install the pipe on a time and materials basis for a not to exceed amount of $750.00. The ditch has already been excavated and the ground is very close to within the proper grade necessary in which to place $Ye900P00 toe. le$3,100.00.total Staff Of l�feels is tthat ion wthis extentionould be iistely necessary as the banks are now much steeper between the houses and the ditch due to the removal of 2-1/2 to 3 feet of materials from the ditch. Fill will be placed in to cover the pipe and brought to a height as to allow a blending together of the 2 yards. Topsoil. seed and proper mulch will then be applied. If the homeowner desires to have sod instead of seed, this could be accomplished by having the homeowners purchase and lay the sod themselves or if this area is completed at the time of the sodding and seeding operation for the Ditch No. 1, Branch No. 5 contract, sod could be layed over this portion as part of the project. The homeowner could then reimburse the City for the cost of the sod under the ditch cleaning contract or if the Council chooses, the City could absorb the cost. The approximate cost for sodding this area would be $920.00. In summary of the storm sewer extension, Staff recommends that the City purchase the pipe and have it delivered on site and hire H.B.H. Contracting to install it. Plans for cleaning Judicial Ditch No. 11 Branch No. 5, were developed by Donohue Engineering. The plans were developed from a field survey done in November of 1986.

During the final day of excavation, Staff observed that this section of ditch appeared high and holding back water. Staff discussed this with Park Construction and examined the plans which indeed showed that this area should be low enough to not require any excavation work. 1'3rk Construction stated that the bid did not include any excavation in this area. The ground was frozen at this time, and it was unclear weather or not we were actually seeing the ground
