provide shade, and an increased foot print to allow for more parking stalls while not removing any mature trees within the park. The parking lot will include B-style concrete curb and gutter throughout, with concrete flumes in the medians. A storm sewer system including catch basins and pipe will be installed at low points in the park drive and medians to take the stormwater runoff. This storm sewer will connect to the system built as part of the 161 st Avenue reconstruction project. The parking lot stalls are proposed to be 20 feet deep and 9 feet wide with 24-foot-wide drive aisles. The total stall count is 232, including 7 handicap stalls. Handicap stall counts are required per the Minnesota Accessibility code, which requires a minimum 7 stalls for total spaces between 201 and 300. Staff is proposing to not include the median landscaping or irrigation system as part of the parking lot reconstruction. This is proposed to be performed separately later this fall. As part of the parking lot reconstruction, conduit will be added for future connection to the existing park irrigation system. Future Central Park Considerations: This project is proposing to only reconstruct the main parking lot and adjacent park drives. The smaller southern parking lot is being reconstructed as part of the 161 st Avenue reconstruction project per City Council direction on December 13, 2022. The parking lot bay across from the hockey rinks and park drive are in the same condition and age as the main parking lot. Construction of these facilities is proposed to be phased to allow for continual use of Central Park by the public. To offset parking loss during fall sports and provide additional parking during the Game Fair, city staff has temporarily stripped the hockey rinks and pleasure rink for parking. An exhibit showing this layout is attached to this case. Preliminary Schedule Remaining: • Council approves plans and specifications / authorizes advertisements for bids o July 25, 2023 • Park and Recreation Commission recommends funding source o August 10, 2023 • Staff Receives Bids o August 18, 2023 • Council awards contract to the lowest responsible bidder o August 22, 2023 • Contractor begins construction o September, 2023 • Contractor substantially completes construction o October 13, 2023 • Landscaping / Irrigation installation o October / November 2023 Attached is the title sheet showing the scope of the improvements. Plans are available upon request from the City Engineer. Time Frame/Observations/Alternatives: Timeframe: Staff anticipates this case will take approximately 15 minutes to present and respond to questions. Observations/Alternatives: Observations: The estimated project costs are approximately 15-percent higher than the CIP Level Estimate of $800,000. This is due to the increased cost of construction seen throughout the year, and anticipated to occur with late season construction, as well as a general increase in storm sewer pipe and structure costs seen this year compared to recent years. Alternatives: Alternative #1: Motion to recommend City Council approve plans and specifications and authorize
