China and Vassalboro have taken different approaches to implementing stricter guidelines for shoreline development beyond those set by the state.
	In China, there are additional requirements for septic systems such as a minimum leach field area and the use of erosion control techniques during construction.  China also has a stricter phosphorus control ordinance which limits the phosphorus export for any land use on the East and West Basin of China Lake.
	Vassalboro in the 1990s required the replacement of all pre-1974 septic systems within the shoreline zone.  However, this did not significantly impact China Lake because most of the land in Vassalboro around the West Basin is undeveloped and owned by the KWD.
	Both towns are in the process of revising a plan to address development in the shoreline zone.
