The existing bituminous pavement was reconstructed using the Stabilized Full Depth Reclamation (SFDR) process. This process included reclaiming the existing bituminous pavement, along with a portion of the existing class 5 aggregate base. The reclaimed material was then spread on top of the remaining class 5 aggregate base, after which about 4 inches of reclaim material was removed from site. An asphalt emulsion was then mixed into the remaining reclaim material as a stabilizing agent to increase the strength of the reclaim material. The stabilized reclaim material was then shaped and compacted, after which 4 inches of new bituminous pavement was placed on top. The new pavement section is a 10-ton pavement design meeting current State Aid pavement design standards. The existing storm sewer system met all current State Aid design standards so no storm sewer improvements were necessary, other than casting adjustments. The existing sanitary sewer and watermain were tested and found to be in good condition so no utility improvements were necessary. Public Input Staff met with all property owners prior to construction to discuss the improvements and their preliminary assessments. All generally understood the need for the improvements, and though many of the property owners questioned the use of special assessments to help pay for the improvements, they did not generally oppose their proposed assessments. Only Connexus Energy continues to voice concerns with their proposed assessment. Notification: Following Council approval, an Assessment Hearing Notice will be published in the City's official newspaper on Friday, September 15th, and Assessment Hearing Notices will be mailed to all benefiting property owners as required per Minnesota State Statute Chapter 429 (attached). Anoka County requires special assessments to be certified to the County Auditor by November 30th for collection on next year's taxes. This deadline will be met by conducting the Assessment Hearing at the October loth City Council meeting. This will also allow adequate time for the required publication and mailing of notices for the hearing. Observations/Alternatives: Observations: At the time this report was prepared, construction was substantially complete with only pavement striping and minor punch list items remaining. Final completion is scheduled to occur well before the Assessment Hearing is conducted on October 10, 2017. Alternatives: Alternative #1 — Motion to adopt Resolution #17-09-213 ordering preparation of a final Assessment Roll, and calling for an Assessment Hearing on October 10, 2017, for City Improvement Project #17-00, Sunwood Drive Reconstruction. Alternative #2 — Motion to deny adoption of Resolution #17-09-213 at this time. Funding Source: The contract amount for this project is $409,385.03. This is $51,742.21, or 11.2%, less than the engineer's estimate of $461,127.24. Final project costs, which include actual construction costs plus 23% indirect costs for administrative (6%), engineering (15%), finance (1%), and legal (1%) costs, are estimated to be $503,543.59. Staff believes the estimated project costs will be relatively close to final project costs since no significant quantity revisions or change orders occurred during construction. A detailed breakout of final project costs will be presented at the Assessment Hearing. These improvements were included in the City's Capital Improvement Plan for 2017 construction. Funding is proposed to include a combination of Street Reconstruction and Overlay Program (SROP) bond funds, special assessments to benefiting properties, and stormwater utility funds.
