Sta1Rtec <br /> Page 2 of 3 <br /> Costs <br /> The county is currently estimating the construction costs of the project (excluding design engineering, land <br /> acquisition and other soft costs) to be in the range of $1.86 Million. Of this, Centerville would be responsible <br /> for approximately $528,000. It is important to remember that these are very preliminary estimates, based on <br /> the layout and design that exists today. We are a long ways from final plans. The breakdown of estimated <br /> costs distributed to the City per County policy is as follows: <br /> • $88,000 — Storm Sewer <br /> o Costs here are based on the typical cost -split policy of each agency paying their share based <br /> on contributing drainage areas. In this case, the city would pay 82% of the cost because <br /> 82% of the drainage area is from outside the county right -of -way. <br /> o While these numbers don't seem too far out of line, the large cost probably makes it worth <br /> our while to take a closer look at their calculations for the cost split. <br /> • $42,000 — Street Improvements <br /> • City pays 50% of curb and gutter costs <br /> • County pays for sidewalk replacement, if necessary. <br /> • $10,000 — Construction Engineering <br /> o Standard policy is for each agency to pay a fee for construction engineering of 8% of their <br /> respective construction costs. This fee covers inspection and surveying costs. <br /> • Optional Costs - $280,000 —Trunk Storm Sewer — 48 -inch <br /> o Most of this cost is wrapped up in the large pipe (which has been upswed to a 48 -inch from a <br /> 42 -inch to squeeze Ina the County's drainage). The County is paying their share of this pipe <br /> and we are paying ours. <br /> • Optional Costs - $78,000 - Sidewalk between Heritage Street and Dupre Road <br /> o City pays 1009yo of new sidewalk <br /> • Optional Costs - $29,000 - Construction Engineering <br /> o Standard policy is for each agency to pay a fee for construction engineering of 8% of their <br /> respective construction costs. This fee covers inspection and surveying costs. <br /> In summary: <br /> Storm Sewer $88,000 <br /> Street Improvements $42,000 <br /> Construction Engineering $10,000 <br /> Minimum Total Cost $140,000 <br /> Trunk Storm Sewer $280,000 <br /> Sidewalk (Meadow to Dupre) $78,000 <br /> Construction Engineering $$29,000 <br /> Total Optional Costs $387,000 <br /> Required Costs $140,000 <br /> Optional Costs $387,000 <br /> Total Costs $527,000 <br />
