On riparian reserve remediation: These need to be 5 meters wide along small waterways. You need to measure at maximum width of the channel (ie. just before it floods, not the regular water's width). In some areas a wider reserve is appropriate if the waterway is upstream of communities (i.e. HCV 5) then the reserve width should 15-30 meters.
In areas of regular and extended flooding, the new RPSP P&C 2013 says there should be a review of suitable areas for planting. Thus, such areas should be left as natural vegetation.
Artificial waterways need not have a reserve. But since good water and soil management needed, for small channels which can transport pollution to natural waterways, there has to be reduced spraying of agro-chemicals within 10-15 meters of the edge of drainage channels linked to such natural water ways. Site planning should also reduce disconnected riparian zones which expand the risk of water pollution.
