CMP Part 3A. Environmental Protection Plan <br /> Orono's Ground Water Supplies <br /> Orono enjoys the same abundant ground water resources from the Twin Cities artesian basin as <br /> does most of the metropolitan area.In addition,our generally heavy clay soil layers near the surface <br /> have protected the ground waters from surface pollution. <br /> Most areas of the City have had no difficulty obtaining potable water supplies drawn from the <br /> Jordan aquifer with wells ranging in depth from 75 to 200 feet. Only occasional wells have had to <br /> go deeper. <br /> Land Cover Summary. In 2006, Hennepin County published the Natural Resource Inventory for <br /> Orono which his included here by reference. The land cover classification encompassed the <br /> entire incorporated area of the City(approximately 15,400 acres)of which€idly 1/3 is open water. <br /> Artificial surfaces, which include residential areas, farmsteads, commercial lands and other areas <br /> with greater than four percent impervious surfaces, accounted for an additional 20% of Orono's <br /> total area. Forest and woodland cover combined accounted for an additional 20%of Orono, with <br /> herbaceous vegetation types (wet meadows, cattail marshes, etc.) and planted-, maintained or <br /> cultivated vegetation types (agricultural crops, hayfields, pastures) each comprising 13% of the <br /> City.
