Sustainable Growth & Agricultural Preservation Act of 2012 Implementation​​

​​The Sustainable Growth & Agricultural Preservation Act of 2012(the septics law) limits the spread of septic systems on large-lot residential development to reduce the last unchecked major source of nitrogen pollution into Chesapeake Bay and other waterways. By mapping future growth in "t​​ie​​rs," the law seeks greater accountability and predictability.
