Completed Improvements The original bituminous pavement and aggregate base sections were removed and hauled off site. Two -feet of unsuitable existing clay subgrade material was also removed and hauled off site. Geotextile fabric was placed on the bottom of the shaped and compacted subgrade, then drain tile was installed along the outer edges of the fabric. Two -feet of compacted select granular borrow (sand) was then placed on top of the fabric and drain tile, and the drain tile was connected to a storm sewer structure allowing for positive drainage of the subgrade at low points. Four -inches of imported aggregate base was then placed and compacted on top of the select granular borrow, followed by 3'/2-inches of new bituminous pavement. The new pavement section provides a 7-ton pavement design, the City standard for residential streets. Ditches were graded after the pavement section was complete and the necessary driveway culverts were replaced. The culvert crossing 180th Lane was replaced, and a storm manhole was added to the middle of the culvert crossing so the drain tile could be connected to the storm sewer system. A swale was also graded across the southeast corner of the property north of 180th Lane and west of Truck Highway 47 to prevent runoff from the ditch from traversing across the property, which had no drainage easement. Construction was substantially complete by mid -July. The proposed improvements are anticipated to have a serviceable life of 60 years, assuming proactive maintenance operations are performed on a regular basis over the life of the improvements. Public Comment Staff conducted a public information meeting for this project on Thursday, November 8, 2018, to present the proposed improvements, estimated costs, funding program, and preliminary project schedule to benefiting property owners, and to receive public input on the project. Property owners from 3 of 8 identified benefiting properties attended. None of the owners objected to the project. Most questions pertained to special assessments and the reasoning behind the School Districts request to expand the cul-de-sac. The residents questioned why the School District asked the City to expand the cul-de-sac now, noting that they observed buses stopping on Highway 47 in other locations. The property owners did not formally object to expanding the cul-de-sac, they just didn't understand why this request was now being made as the residents said they had asked the School District to pick students up and drop them off on the cul-de-sac years ago when there were many more children in the neighborhood, yet their request was denied. One property owner attended the Public Hearing on November 2018 again questioned why the School District wanted to enlarge the cul-de-sac. Staff has contacted the School District numerous times since and has received the same answer each time. The School District confirms that buses will not be allowed to stop in dedicated turn lanes on Highway 47 and will need to turn onto 180th Lane to pick up and drop off kids starting this fall, and will therefore need the cul-de-sac expanded so buses can turn around. Per City Council direction, the cul-de-sac was expanded to accommodate the School District's request. Per the City's Special Assessments Policy, costs to expand streets are ineligible for assessments so the costs to expand the cul-de-sac will be paid in full by the City. Staff met with numerous property owners during construction to coordinate construction of various improvements adjacent to or otherwise affecting the use of their properties. At the time this case was prepared, two benefiting property owners had inquired about their ability to defer assessments, though neither requested a deferral form, and one of these property owners stated they might submit a letter before or during the public hearing requesting forgiveness of their assessment in exchange for an easement. If this request is made at the hearing, Staff will be prepared to provide more details to Council and to respond as needed. If any formal comments or objections are received after this case is published, Staff will share this new information with Council prior to the Public Hearing. Notification:
