I <br />I <br />I <br /> <br />I <br />I <br /> <br />I <br />I <br /> <br />5.0 <br /> <br />An eight (8") inch stub out at the western end of 152nd Ave. is proposed to <br />receive .sanitary sewage flows from the san_itary sewer system proposed in the <br />adjacent Helium Street Extension project. However, no extraordinary depth was <br />provided in the sewer design to maximize the upstream reach to properties <br />outside the current project boundary. Where the adjoining property is. <br />undeveloped, four-inch services will be provided at 85' intervals or as directed by <br />the property owner. <br /> <br />See "EXHIBIT C" for detailed description of the proposed sanitary sewer system <br />improvements. The alignment of the sanitary sewer may change at the time of. <br />final design. <br /> <br />ESTIMATED COSTS <br /> <br />The detailed estimate of construction cost for all of the improvements are shown <br />in "EXHIBIT D". The estimated cost of the construction and easement items to <br />be shared with C.O.R. Project 02-20 are shown in "EXHIBIT E" <br /> <br />The estimated project costs presented herein reflect the construction, right-of- <br />way or easement, and overhead costs. Construction costs are estimated <br />contract amounts for the actual construction.. Right-°f-way for construction of <br />streets is calculated for a 60-foot wide right-of-way. Easement costs include <br />providing a 20-foot permanent easements along the off-right-of-way route of the <br />water, sanitary or storm sewers. The cost of easements for construction of the <br />detention basins is alsc~ included. <br /> <br />· It was assumed that temporary construction easements would be provided at no <br /> cost. If easements cannot be obtained through negotiation, eminent domain will <br /> be required. The cost of condemnation is not included in the cost presented <br /> below, 'and would' increase the .necessary assessment to finance the project. <br /> <br /> Overhead costs include, but are not limited to, engineering, construction staking <br /> and inspection, administrative service, legal, and .contingency. Overhead costs <br /> for the project are estimated based on percentages-of construction cost. Those <br /> percentages are estimated to be as foilows: <br /> <br /> · Engineering 9% <br /> <br /> · Staking & Inspection 7% <br /> <br /> · Bonding & Legal 2% <br /> <br /> · City Staff Administration 5% <br /> <br />Contingencies 10% <br /> <br />Page 6 <br />G:\Municipal~RAMS EY\633\RA633FSR.doc <br /> <br />-38%9 <br /> <br /> <br />
