Proposed Improvements The existing bituminous pavement and aggregate base will be removed along with 2-feet of unsuitable subgrade materials. Geotextile fabric will be placed over the shaped and compacted subgrade. Two -feet of compacted select granular borrow (sand) will be placed over the fabric. Drain tile will run along the outside edges of the geotextile fabric and will be connected to a storm sewer structure to help drain low points. Then, four -inches of imported aggregate base will be placed, followed by 3'/2-inches of new bituminous pavement. This results in a 7-ton pavement design, which is the City standard for residential streets. Existing ditches will require re -grading due to the subgrade corrections. Some driveway culverts will also require replacement. The culvert crossing 180th Lane will also be replaced, with a storm manhole placed in the center of the street to accommodate drain tile connections. A new swale will also be graded across the southeast corner of the property in the northwest corner of the intersection of 180th Lane and Highway 47.

The purpose of the meeting was 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 the 8 identified benefiting properties attended. None of the owners objected to the project. Most of the questions pertained to special assessments, as well as the reasoning behind the School Districts request to enlarge the cul-de-sac. The residents questioned why the School District would ask the City to expand the cul-de-sac when they continue to see buses stop on Highway 47 in other locations. The property owners did not formally object to increasing the size of the cul-de-sac, they just didn't understand why this request was being made now as they asked the School District to pick up and drop off kids in the cul-de-sac years ago when there were far more kids in the neighborhood, yet their request was denied. Now they say there are only a few kids in the neighborhood and the cul-de-sac expansion will increase project costs, and possibly their assessments, so they wanted to better understand if other options are available. One property owner that attended the Public Hearing later in November again questioned why the School District wanted the cul-de-sac to be enlarged at this time. Staff has been in contact with the School District numerous times over the last several months and has received the same answer numerous times. According to the School District, buses are not allowed to stop in dedicated turn lanes along Highway 47 so they need to turn onto 180 th Lane and therefore need a larger cul-de-sac to turn around. Staff prepared final plans and specifications to include an alternate bid for enlarging the Krypton Street cul-de-sac as requested by the School District. Per the City's Special Assessments Policy, Staff would recommend that this cost be fully paid by the City since it would expand the existing width, which is considered an ineligible cost in the policy.
