The existing storm sewer system consists of concrete catch basins that collect stormwater runoff from the curb and gutter, and concrete storm sewer pipes that route the runoff to stormwater ponding areas where the runoff is stored and treated. The storm sewer system was also inspected was generally found to be in good operating condition so only minor maintenance work is proposed including re -grouting some structures and resetting castings. One sewer pipe has a small hole near the top of the pipe, potentially caused by a boring machine while installing a private utility. This hole will be inspected during construction to see if the hole requires a patch. Proposed Improvements All damaged concrete curb and gutter sections are proposed to be removed and replaced. The existing bituminous pavement section will be reconstructed using the Full Depth Reclamation (FDR) process, which involves reclaiming the existing bituminous pavement section, along with a portion of the underlying aggregate base. The reclaim material generated by this process is then spread over the reshaped and compacted existing aggregate base between the curb and gutter. Excess reclaim material is then removed and hauled off site to allow 3'/2-inches of new bituminous pavement to be placed over the remaining compacted reclaim material. This results in a 7-ton pavement design, which is the City standard for residential streets. Proposed project schedule: March 26 — Approve Plans and Specifications / Authorize Ads for Bids March 29 & April — Publish Ads for Bids (Anoka Union Herald, Finance & Commerce) May 1 — Public bid opening May 14 — Accept Bids / Award Contract Late May / early June — Begin construction August 16 — Substantial completion (open to traffic) September 10 — Order Assessment Hearing October 8 — Conduct Assessment Hearing Public Comment Staff conducted a public information meeting on Wednesday, November 7, 2018. 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 59 identified benefiting properties attended and none of the property owners generally objected to the project, and most of the questions pertained to special assessments, particularly payment options. Since then, no additional public comment has been received. Notification: Public notifications were not required in advance of this case. Upon Council authorization, advertisements will be published in the Anoka Union Herald and in Finance & Commerce on March 29 and April5, 2019, as required per State Statute. Observations/Alternatives: Observations: The proposed improvements should have a serviceable life of 60 years, assuming that proactive maintenance operations are performed on a regular basis during the life of the improvements. Some properties may have private irrigation systems. Impacts to these systems may occur because of the proposed improvements. Staff will notify property owners in writing of the pending construction as far in advance of construction as possible to allow them time to move their irrigation system components away from construction activities. After the project is complete, property owners may replace irrigation systems in their previous locations if desired. As previously discussed, all costs to relocate private irrigation system components will be the responsibility of the property owners. However, if private irrigation systems are damaged due to negligence on the part of the City's contractor, the contractor will be responsible to repair the damage.
