The Oregon Land Conservation and Development Act of 1973, formally Oregon Senate Bills 100 and 101 of 1973 (SB 100 and SB 101), were pieces of landmark legislation passed by the Oregon State Senate in 1973 and later signed into law. It created a framework for land use planning across the state, requiring every city and county to develop a comprehensive plan for land use.
SB 100 expanded on Senate Bill 10 (SB 10) of 1969. This legislation created the Oregon Land Conservation and Development Commission (LCDC), which expanded on the statewide planning goals of SB 10.[1] It also established the Oregon Department of Land Conservation and Development.
