ARDEN HILLS CITY COUNCIL WORK SESSION – JULY 20, 2020 12 Mayor Grant asked if regarding the 2020 General Fund balance the Council would like to take the overage and apply it to the purchase of the fire station property. Council agreed. Finance Director Bauman said the plan includes an increase to the tax levy to the Public Safety Fund in anticipation of the new fire station. Should staff move forward with that assumption and go forward with the 2021 budget? Council agreed. Finance Director Bauman said she would like to know what equipment purchases they’d be comfortable putting into the 2021 CIP. Each of them would still have to come forward to the Council for final approval. Public Works Director/City Engineer Blomstrom said they should have information regarding the planning and maintenance of equipment by the end of the week. A weighted average PCI for the City would be done by end of the week as well. Mayor Grant asked to see that information before they make decisions on equipment. They would come back to the CIP at a future meeting. D. Environmental Investigation for Snelling North Avenue Public Works Director/City Engineer Blomstrom said the City initiated a feasibility study for the project in late 2019. During the geotechnical investigation process for the feasibility study, the soil boring company reported “Apparent Hydrocarbon Odors” at 11 of the 15 soil boring locations. The City hired WSB to conduct an environmental investigation to assist with identification of potential contaminants within the project. He is asking if the Council wants to proceed with a Response Action Plan and a Construction Contingency Plan. Staff is also seeking direction if the City Council wishes to continue considering construction of a new trail to the south of County Road E. Mr. Blomstrom described the three project alternatives for Snelling Avenue North as outlined in the agenda memo. Mr. Spenser said WSB completed environmental due diligence on an approximately .8 mile stretch of Old Snelling Avenue. As part of that a Phase I Environmental Assessment was completed to research the history to try to find what was causing the petroleum odors from the borings. There were two environmental conditions (REC’s), one was the notation of the petroleum odor, the other was contaminated soils that were noted during a bridge replacement in 2018 that required correction due to elevated volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and diesel range organics (DRO). The soils had to be exported to a landfill. Results of Phase I recommended Phase II, which involved collecting data of soil, groundwater and soil vapor. That was completed in April 2020. Fourteen borings were taken. They found a few areas with elevated contamination in the soil that if disturbed would require special handling of material. WSB is recommending a Response Action Plan be prepared in preparation for any future improvements of the roadway. That document will guide the contractor
