Future Business Park study that was completed for this area of the City. Lift station MLS- 5 was added to the improvements required for this subdistrict. All project costs have been updated to 2016 unit prices. 3. Subdistricts R21 Through R25 These subdistricts are located north of Trott Brook in the north central portion of the City. No layout revisions to these trunk extensions were made. All trunk line project costs have been updated to current 2016 unit prices. 4. System Extension for 167th Avenue Future MUSA Study Area The Future MUSA Study Area identifies an area to better understand the feasibility of extending a trunk sewer line to the 167th Avenue/Saint Francis Boulevard (TH 47) land use node. Municipal Water service exists to the area, but Sanitary Sewer does not. The City has a land use goal to revitalize this node and surrounding area, and the availability of Sanitary Sewer is a major variable in future land use decisions. The MUSA boundary does not currently include this area. Findings from this study area will be utilize to influence the City's 2040 Comprehensive Plan Update and discussions with private developers currently proposing certain land use scenarios. C. TRUNK SANITARY SEWER SYSTEM COSTS Attached are the updated cost estimates related to the above revisions, totaling $8,432,995. These costs include 25% for indirect costs such as administration, engineering, legal and financing. Additionally, we have included a 20% contingency for unforeseen improvements which may be required during the study period, for a total cost of $10,119,594 in 2016 dollars. The City' s current Capital Improvement Plan was used to determine expenditures for the years 2016 to 2020. For the years 2021 to 2040, the above described costs were spread evenly over the 20 year period, while being inflated at a rate of 3% per year. D.
