X City of Arden Hills Page 15 of 63 October 7, 2022 o The project could potentially score well in this category as an “in -fill” project providing extension and continuation of existing SRTS projects and connections to several school facilities and neighborhoods Community Development Block Grant - A portion of the trail may be eligible for CDBG funding. Eligible areas will need to be confirmed with further income surveys to determine eligibility requirements. Minnesota Department of Natural Resources (MnDNR) - $5,000 - $250,000 per grant, 25%$ local match - Regional trail Grant Program - Local Trails Connection Program - Parks and Trails Fund (Potential with connection to regional and County trails) 8.0 GEOTECHNICAL EVALUATION 8.1 DESCRIPTION This project includes a geotechnical evaluation task to help determine underground soil conditions and water table elevations and their implications to the proposed trail project. The primary portion of this task involved taking soil borings and developing a Geotechnical Evaluation Report, both of which were performed by Braun Intertec Corporation. The remainder of this task is presented here, involving summarizing the recommendations of the report and giving additional context to them for implications to the proposed trail project. Refer to Appendix C for a copy of the Geotechnical Evaluation Report. 8.2 RESULTS Thirteen soil borings were taken as a part of this evaluation. Based on the Soil Boring Location Sketch in the Geotechnical Evaluation Report, they appear to be spaced approximately evenly just off the west side of Old Snelling Ave. / Old Highway 10 from Lakeshore Pl. south to Lake Valentine Rd. Three of the borings included pavement at the surface and may have been taken along the paved roadway shoulder. These borings indicated the presence of three to four inches of bituminous over eight to ten inches of concrete, over eight to ten inches of aggregate base. Sub-surface conditions were highly variable. Topsoil fill varied from absent to 1.5 foot thick and fill included intermixed soils with variable gravel content and possible cobbles and boulders. Glacial deposits were encountered below the fill within two borings and contained variable amounts of gravel with the potential to contain cobbles and boulders. No groundwater was observed while performing the borings. The moisture content of the soils tested on selected penetration samples varied from approximately 12 to 25 percent, indicating that the materials were likely near the probable optimum moisture content. The organic content of selected sample material tested was about two percent.
