then freeze in the winter resulting in unsafe conditions for drivers and pedestrians. The existing bituminous pavement will be reconstructed using a process called Stabilized Full Depth Reclamation (SFDR). The SFDR process would include milling the top 3 inches of existing bituminous pavement and disposing of the millings off site. The remaining 13/4 inches of existing bituminous pavement will then be reclaimed (ground up and mixed) along with about 4 inches of existing class 5 aggregate base. Approximately 1 inch of reclaimed material will need to be removed from site, then an asphalt emulsion will be mixed into the remaining reclaim material. This stabilized reclaim material will be shaped and compacted into a 5 inch lift, then 4 inches of new bituminous pavement will be placed on top of the compacted stabilized reclaim material. This new pavement section will result in a 10-ton pavement design meeting current State Aid pavement design standards. The existing storm sewer system is in good condition and based on preliminary review appears to meet all applicable current State Aid design standards meaning no improvements are proposed, other than casting adjustments as needed. An off-street 10 foot bituminous bike trail exists along the north side of Sunwood Drive which is in relatively good condition so no improvements are proposed to the trail as part of this project. Estimated Costs The engineer's opinion of probable costs for completing the proposed improvements on Sunwood Drive as outlined in the Feasibility Report is $607,000. Estimated costs include 23% indirect costs for administrative, engineering, finance and legal costs. A summary of the engineer's opinion of probable costs is included in Appendix B of the Feasibility Report. Funding Sources The improvements are proposed to be funded using a combination of Street Reconstruction and Overlay Program (SROP) bond funds, stormwater utility funds, and special assessments to benefiting properties. The majority of the proposed improvements will be funded using SROP bond funds, which will be paid back over a 10 year term using the general fund. This cost is estimated at $447,950 in the Feasibility Report. Stormwater utility funds will pay for required storm sewer improvements estimated to cost $7,300. Special assessments are proposed to fund 25% of eligible construction costs totaling $151,750 as per the City's adopted Special Assessments Policy. A total of 9 parcels have been identified as receiving special benefit from the improvements. These parcels are identified in the preliminary Assessment Map and Roll inAppendix C of the Feasibility Report. Special Assessments When special assessments are proposed to pay for all or a portion of the cost of an improvement, the objective is to choose an assessment method which will result in a reasonable, fair and equitable assessment that is uniform upon the same class of property within the assessed area. Per the City's adopted Special Assessments Policy, staff recommends using special assessments be pay for 25% of eligible improvement costs which totals $151,750. This amount must then be distributed across the 9 parcels which staff has identified as benefiting properties. In doing so, it is important to recall that the test for determining the validity of a special assessment is whether the improvement for which the assessment was levied has increased the market value of the property against which the assessment was levied in at least the amount of the assessment. The Special Assessments Policy identifies three optional methods for assigning assessments. The 9 identified benefiting properties are zoned industrial (El or E2). Only two assessment methods are recommended for assessing industrial parcels, these being the "adjusted front footage" and "area" methods. Staff completed a cursory review of both methods as they would be applied in their current context within the policy which showed that the adjusted front footage method results in less variance between assessments ($9K - $40K), whereas applying the area method results in assessments that are more variable ($3K - $42K). Based on the geometry of the assessable parcels, including significant differences in lot depth, staff recommends applying the area method so assessments are more equitable to the benefit received. Staff then reviewed all assessable parcels to determine what appreciable differences existed between parcels that would impact the benefit received from the proposed improvements. Staff determined there are two significant
