Orono’s wetland ordinance addresses the damaging effect of runoff rate and pollutant loading <br />on wetland vegetation and wetland fauna. Through a wetland inventory based on wetland functions and <br />values, Orono and MCWD have established functions and values based protection program that protects <br />wetlands in proportion to their susceptibility to stormwater impacts with higher levels of protection <br />provided for Orono’s most sensitive wetland resources. <br />WATER QUALITY <br />Orono's natural setting and proximity to the Twin Cities makes it a desirable location for both residential <br />development and recreational activities. As the population of Lake Minnetonka's shoreland increased, <br />and as recreational use grew, residents indicated a strong desire to maintain and improve the quality of <br />Lake Minnetonka. It has been demonstrated that surface waters, as biological systems, can be negatively <br />affected by increases in nutrients and toxic chemicals. Phosphorus is the nutrient most commonly <br />managed because it is the limiting nutrient in the growth of algae and vegetation in lakes and wetlands. <br />Soil erosion and sedimentation also play a significant role in poor water quality.
