Site Reconnaissance <br /> <br />6.1 Methodology <br /> <br />WSB conducted a site walkthrough and reconnaissance of the Project Corridor, adjacent sites <br />and surrounding area on February 20, 2020. The site walkthrough included accessing all areas <br />of the Project Corridor for visual observation. A roadside assessment, limited to the public right- <br />of-way, was conducted for adjacent sites and the surrounding area. <br /> <br />6.2 General Site Setting <br /> <br />The Project Corridor is in a primarily residential area situated between Lake Johanna and Lake <br />Josephine in Arden Hills, Minnesota. The adjacent sites and area surrounding the Project <br />Corridor consists of single-family residential properties with a commercial site located at the north <br />end. The Project Corridor gradually slopes to the south. The Project Corridor can be accessed <br />from County Road E to the north, TH-51 to the south, or from any of the additional cross streets <br />and driveways located adjacent the Project Corridor. <br /> <br />6.3 Interior and Exterior Observations <br /> <br />WSB conducted observations of the Project Corridor, adjacent sites, and surrounding area on <br />February 20, 2020. Site reconnaissance photographs are included in Appendix A. A summary <br />of the site reconnaissance is outlined in the table below: <br /> <br />Site Reconnaissance Summary Table <br />Issue <br />Observed <br />During Site <br />Visit <br />Comments <br /> Yes No <br />Aboveground / Underground <br />Storage Tanks X None observed. <br />Drums/Containers X None observed. <br />Animals X None observed. <br />Buildings/Structures X <br />Residential dwellings and a commercial <br />building were observed at the adjacent <br />sites. <br />Construction/Demolition <br />debris X None observed. <br />Drainage Ditches/Culverts X <br />A culvert/bridge (Bridge 62J17) is <br />located at the south end of the Project <br />Corridor. <br />Dirt/Spoil Piles X None observed. <br />Floor Drains /Sumps/Vaults X None observed. <br />Hazardous <br />Substances/Petroleum <br />Products <br /> X None observed. <br />Landfills X None observed. <br />Odors X None observed. <br />Oil/Water Separators X None observed. <br />Pipelines or Utilities X <br />Overhead powerlines are located along <br />the western boundary of the Project <br />Corridor.
