STAFF REPORT DATE: February 21, 2023 REGULAR AGENDA ITEM: Approve Resolution Approving Plans and Specifications and Ordering Advertisement for Bids for the Old Village Phase 7 Street and Utility Improvements SUBMITTED BY: Jack Griffin, City Engineer REVIEWED BY: Kristina Handt, City Administrator Marty Powers, Public Works Director Chad Isakson, Assistant City Engineer ISSUE BEFORE COUNCIL: Should the City Council approve the Plans and Specifications and Order the Advertisement for Bids for the Old Village Phase 7 Street and Utility Improvements? BACKGROUND: The City of Lake Elmo is extending sanitary sewer to serve the existing properties in the Old Village MUSA area to replace the use of private on-site sewage treatment systems. The Old Village Capital Improvement projects also include drainage improvements to continue addressing historic flooding issues in the Downtown area, the replacement of aged watermain pipes and reconstructing the public streets that are disturbed during the work. The Improvements are being constructed in phases and through separate projects. The first six phases were constructed in 2015, 2016, 2017, 2018, 2021 and 2022. The final phase of the Old Village Capital Improvement Plan, Phase 7, is programmed for construction in 2023. Completion of final construction documents was ordered by the City Council on November 1, 2022 and the City Council held a public improvement hearing and ordered the improvements on December 6, 2022. PROPOSAL DETAILS/ANALYSIS: The plans and specifications have been completed for the improvements and are ready to be advertised for contractor bids. A bid date has been scheduled for March 23, 2023. Contractor bids will be reviewed by staff after they are opened. Information will then be presented to the City Council at the April 4, 2023 meeting where the council will be asked to conduct a final assessment hearing and consider award of contract. The Old Village Phase 7 Street and Utility Improvements includes the extension of public sanitary sewer and construction of a city owned lift station to serve the existing 24 platted properties located along Legion Avenue North, south of 30th Street. Installation of public sewer will replace the use of private individual on‐site sewage treatment systems and the Old Village Remote A 201 Community Wastewater Treatment System. The city owned 201 system currently serves 8 of the existing 24 properties. The community drain field and private septic systems will need to remain in service during construction but will be decommissioned as a part of the improvements. The proposed improvements include the replacement of the aged existing 6‐inch watermain along Legion Avenue with an 8-inch watermain from 30th Street to the dead end. Hydrants and water services from the main to the property line will be replaced as well. The proposed improvements also include the reconstruction of the public streets disturbed by the sanitary sewer and watermain utility installations, consisting of a reconstructed bituminous street with new concrete curb and gutter. The street segment of Legion Avenue was last paved in 2009 and is in relatively good condition. Reconstruction of the street is required at this time due to the impacts of the utility installations.
