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. Municipal utilities (sanitary sewer and watermain) exist under each of the streets. These utilities were inspected and were found to be in good operating condition so no improvements are proposed at this time. 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. Bids On May 1, 2019, four (4) sealed bids were received and were publicly opened.
