•October 10, 2023, Resolution#23-252 the Ramsey City Council accepted proposals for sewer cleaning and televising. •January 16, 2024,the Ramsey Public Works Committee considered recommending City Council approval of plans and specifications and authorizing advertisement for bids. Pavement History The streets within Juniper Woods 1st and 2nd were built in 1990, and Juniper Woods 3rd was built in 1993. Since construction,the only large pavement maintenance was crack seal/seal coat improvements to 1st and 2nd additions in 1995, and crack seal/seal coat improvements to all the streets in 2001. Maintenance crews have performed patching as needed over the last several years. 150h Lane in particular has received pothole patching on an annual basis for several years. Proposed Improvements Staffs review of the geotechnical report found generally sandy subsoil makes up the roadway embankment throughout the project area,which is excellent for both utility installation and roadway support. As mentioned previously, storm sewer utility improvements are proposed to be limited to three short runs of storm sewer piping. Additionally, catch basins will be re-grouted as part of the project. Also,the project proposes replacing the existing sanitary sewer castings which are no longer specified, to the new castings. In general,the existing concrete curb and gutter is in good condition and only spot replacements are proposed. Restoration of the impacted boulevard areas will include a minimum of 4-inches of topsoil and hydroseed with a residential turf seed mix. Because of the existing pavement section thickness, and the excellent sand subsoils, Staff is proposing a reclamation rehabilitation for this project. This will include reclaiming(grinding up)the existing bituminous pavement and underlying aggregate base, approximately 6.5-inches thick. 2.5-inches of excess material will be removed,with the remaining 4-inches being shaped and compacted to remain as the new aggregate base. Finally, 2.5-inches of new bituminous will be placed on top in a single lift. During design site review, Staff noted the 300-foot segment of Waco Street between 150th Lane and 150th Avenue are in very poor condition. This was also commented on by residents at the November 9th open house meeting held at City Hall. The remaining Waco Street north to Alpine Drive is in considerably better condition, and listed in the CIP as a street reconstruction in 2033. To avoid potentially 9 seasons of pavement patching, and bring overall cost savings to the City, Staff included this segment of Waco Street in the project. An existing 8-foot wide bituminous trail runs in backyards from Waco Street south of 150th Lane to Alpine Drive,where there is an existing curb cut,but no crossing. The City's general budget allocated$120,000 in 2024 to repave trails. Typically, the Parks Department sends out requests for proposals to perform this trail repaving work. Engineering and Parks Department Staff worked together and determined it would be both more efficient and cost-effective to include the trail repaving as part of this project,rather than a stand-alone. The work will include removing approximately 12 undesirable trees which are immediately adjacent to the trail, including roots under the trail which cause trip hazards because of tenting of the pavement. The existing trail and underlying aggregate base will be reclaimed, in the same manner as the street pavement, and compacted in-place. 2.5-inches of new bituminous pavement will be placed on top,with topsoil and hydro-seeding placed on the edge to taper into the existing ground. ADA compliant pedestrian ramps are required at the trail crossing at 150th Lane. The project is proposing to remove the curb cut at Alpine Drive,which is mid-block and has no landing on the north side of Alpine Drive. An 8-foot trail will be extended in the south boulevard of Alpine Drive over to Ute Street, approximately 150 feet east. A pedestrian ramp will be placed at Ute Street, lining up with the pedestrian ramp on the north side of Alpine Drive. Staff is proposing to bid the trail as an alternate bid,to split out the cost, in case the bid prices come in higher than the $120,000 budgeted funds allow for.
