Does anyone here have experiance dealing with the Islands Trust (By Vancouver Island) prohibiting Erosion Protection on an ocean front property? They have a bylaw that prohibits structures within 7.5m of the waterline but erosion control is not defined as either a structure or not a structure in ther bylaw (http://www.islandstrust.bc.ca/ltc/gb/pdf/gbbylbaselub0177.pdf). Pavement and sidewalks are specifically excluded as structures. Retaining walls are defined as structures. The erosion control to be provided does not retain any soils as the slope is competant glacial till over shale and about 7m high at a 1H:1V incline. The slope only needs protection from the wave action of the ocean. The bylaw states in another section that the standard building setback may be reduced if the slope is bedrock or has works to control erosion that have been certified by a professional engineer. I think that this section would show that erosion control is allowed. Incidently DFO and the RDN have approved the works. Any thoughts?  

Fabriform concrete mats might be allowed as erosion control.They are not used frequently in BC but BC hydro has occasionally installed fabriform downstreem from their dams.
