 =====Background===== =====Background=====
  
-The {{https://www.countyofdane.com/documents/pdf/ordinances/ch014.pdf|Erosion Control and Stormwater Management Ordinance}} was designed to help protect Dane County’s lakes, streams, wetlands and quality of life by reducing the negative impacts of sediment, rainfall, melting snow and other water runoff. +The {{https://www.danecounty.gov/documents/pdf/ordinances/ch014.pdf|Erosion Control and Stormwater Management Ordinance}} was designed to help protect Dane County’s lakes, streams, wetlands and quality of life by reducing the negative impacts of sediment, rainfall, melting snow and other water runoff. 
  
 The ordinance establishes countywide standards for the quantity and quality of water that runs off land under construction in urban and rural areas, including farms.  It also provides flexibility in meeting those standards, recognizing the unique characteristics of each project and site.  The Erosion Control and Stormwater Management Ordinance builds on the construction site erosion control requirements that have been in effect since 1995. The ordinance establishes countywide standards for the quantity and quality of water that runs off land under construction in urban and rural areas, including farms.  It also provides flexibility in meeting those standards, recognizing the unique characteristics of each project and site.  The Erosion Control and Stormwater Management Ordinance builds on the construction site erosion control requirements that have been in effect since 1995.
