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 and is included here by reference. The land cover classification encompassed the entire <br />incorporated area of the City (approximately 15,400 acres) of which fully 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.
