<br />COMMENTARY - SHEET 3 OF 12 <br /> <br />COST ESTIMATE - SHEET 3 OF 12 <br /> <br />Grade stabilization structures are recommended to maintain the existing <br />channel and reduce degradation problems which may occur. The cost estimate <br />for Sheet 3 of 12 reflects improved channel maintenance and the construction <br />of thirteen grade stabilization structures. <br /> <br />ITEM <br /> <br />Channel Improvements <br />Street Crossings <br />Utility Relocation <br /> <br />In regard to the Cressmans Gulch channel and floodplain, the commentary for <br />Sheet 2 also pertains to this sheet. <br /> <br />The replacement of the North Ford Street crossing of Tucker Gulch was studied <br />in Phase A and found to be not economically justified. As a result, an <br />improved crossing is not part of the recommended plan. However, should the <br />crossing be severely damaged or washed out in the event of a flood, or when <br />major street improvements are justified by factors other than flooding, a 100- <br />year design crossing should be considered utilizing hydrologic data presented <br />in this report. <br /> <br />Subtota 1 <br />Contingencies (15%) <br /> <br />Engineering, Legal & Administrative (15%) <br /> <br />TOTAL CONSTRUCTION COST <br /> <br />Right-of-Way Acquisition <br /> <br />TOTAL CAPITOL COST OF IMPROVEMENTS <br /> <br />The recommended plan for this reach is floodplain regulation. <br /> <br />TOTALS IN EACH JURISDICTION <br /> <br />City of Golden <br />Jefferson County <br /> <br />Annual Operation and Maintenance Costs <br /> <br />COST <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />$ 84,500 <br />-0- <br />-0- <br /> <br />84,500 <br /> <br />12,675 <br />12,675 <br /> <br />109,850 <br /> <br />-0- <br /> <br />109,850 <br /> <br />76,050 <br />33,800 <br /> <br />(3,300) <br />
