The Lower Mainland Regional Planning Board of B.C. (LMRPB) was created in 1949 and consisted of "representatives of the municipalities and unorganized areas of the Lower Fraser Valley with jurisdiction from Vancouver to Hope." The LMRPB was "authorized and governed by the Municipal Act," by which it was "charged with the duty of preparing plans for the physical development of the Region." The LMRPB was funded by its member municipalities in conjunction with the Government of British Columbia - Department of Municipal Affairs. Among the activities of the LMRPB were the preparation of regional and municipal planning reports which included zoning and street plans, creation of large-scale land use maps, devising house numbering systems, and performing studies and surveys on a range of topics, including: industrial land, Boundary Bay, land use mapping, Delta, and water supply. The LMRPB continued to function until April 1, 1969 when it was absorbed by the four Regional Districts: Greater Vancouver Regional District (GVRD), Dewdney-Alouette, Central Fraser Valley, and Fraser-Cheam.
