Council approves $60,000 geotechnical task order for Woodland Cove Outlot B as water‑system design advances
Summary
Minnetrista City Council approved a task order for geotechnical services (roughly $60,000) for Outlot B in Woodland Cove to support design of an on-site water treatment/clear-well; staff said deeper borings and expanded lab testing are needed because of unknown fill and variable soils and that design can proceed in parallel while testing occurs.
The Minnetrista City Council approved a task order to fund geotechnical services for Outlot B in the Woodland Cove eleventh addition to support planning for a water treatment plant and clear well. Council members asked whether the geotechnical scope and cost would delay the overall project; staff said the subsurface testing and laboratory analyses are more extensive than typical street borings and are necessary to design foundations and storage tanks.
An unidentified staff speaker explained the higher cost: "When council typically sees geotechnical services, it's for street improvement projects where the borings are about 20 feet deep. This is a lot more complex because... we have deeper borings and a lot of other testing that's being done on these samples," and the task order includes laboratory testing and reporting to support building design. Staff estimated roughly 60 days for drilling and laboratory work (two 30‑day phases) and said some design work can proceed in parallel; the results will inform foundations, possible pilings and layout adjustments.
Speakers flagged uncertainty about site fill and noted previous nearby projects had extensive excavation. Staff said they coordinated scope with AE2S and trimmed duplicated work where possible to reduce cost; survey work already approved was described in the meeting as approximately $9,000–$14,000. Council members asked whether the geotechnical findings could force a change of site; staff said the usual remedies would be deeper footings or pilings and that the team expects to adapt design rather than abandon the site.
Additional regulatory constraint: staff also warned that Minnesota Department of Natural Resources (DNR) monitoring-well requirements and approvals for water wells are another critical path item and are producing extra requests for information that the city must respond to.
Vote and next steps: The council approved the task order (voice vote, 5–0). Staff will complete borings, lab testing and reporting and will notify council if testing identifies any need for major design changes or additional budget requests.
