Mr. Adam Edwards March 5, 2021 Page 2 G:\.Clients All\Orono\Proposals\2021 Public Works Facility Sewer and Water Design\20210305 AEdwards PROP utility extension to PW facility Final.docx anticipated project schedule adjustments that may be necessary based on the outcome of these discussions. Deliverables: project schedule adjustments (if any), and BNSF and MNDOT perm its necessary for construction. Task C: Geotechnical Evaluation WSB’s fee includes two soil borings to a depth of 15 feet. Based on a review of the information provided, it appears that the site can be accessed with our CME-55 Track- mounted auger drill. WSB will complete Gopher State One Call (GSOC) utility clearance to have public underground utilities located. Private utilities are the responsibility of the site owner to mark, and WSB should be notified of any private underground utilities onsite. If borings are extended due to unsuitable soils at termination depths (organics, fills, etc), an additional charge of $20 per lineal foot will be assessed. Samples retrieved during drilling will be returned to our laboratory where they will be reviewed, classified using the Unified Soil Classification System (USCS) and logged under the direction of a geotechnical engineer. Select samples will be set aside for laboratory testing. We may perform routine laboratory tests on selected soil samples obtained from the exploration. Deliverables: Geotechnical Evaluation Report. Task D: Survey and Mapping Topographic survey will be collected on the north and south ends of the anticipated pipe boring location as needed to complete the work identified in Tasks E and G. GSOC Design locates will also be completed as part of this task. Task E: Utility and Stormwater Management Design The sewer and water service sizes will be based on a facility that is 120% of the size of the existing Public Works Facility located at 365 Old Crystal Bay RD. The sanitary sewer will serve the building wastewater needs and the watermain will serve the building water needs as well as bulk water demand (e.g. brine making). The project will be located entirely within the Minnehaha Creek Watershed District (MCWD) boundary. Linear projects including utility construction that create less than 10,000 sq-ft of new impervious are exempt for the stormwater management rule. Therefore, we do not anticipate any permeant stormwater management design will be required for this project. There also does not appear to be any wetland or floodplain impacts as a result of the work outlined in the RFP. Deliverables: Design Memo outlining water and sewer sizing requirements. Task F: Environmental Documentation and Permits Based on the information provided in the RFP we anticipate that the following permits will be necessary: • MCWD Erosion Control Permit (Required for disturbance greater than 5,000 sq-ft of 50 CY) • MDH Watermain Permit • MPCA Sewer Extension Permit
