Any urban renewal project undertaken pursuant to the preceding section shall be undertaken in accordance with an urban renewal plan for the area of the project. As used in this article, an "urban renewal plan" means a plan, as it exists from time to time, for an urban renewal project, which plan (1) shall conform to the general plan for the community as a whole, except as provided for disaster areas, and (2) shall be sufficiently complete to indicate such land acquisition, demolition and removal of structures, redevelopment, improvements, and rehabilitation as may be proposed to be carried out in the area of the urban renewal project, zoning and planning changes, if any, land uses, maximum densities, building requirements, and the plan's relationship to definite local objectives representing appropriate land uses, improved traffic, public transportation, public utilities, recreational and community facilities, and other public improvements. An urban renewal plan shall be prepared and approved pursuant to the same procedure as provided in this article with respect to a redevelopment plan. Where real property acquired by a community is to be transferred in accordance with the urban renewal plan, any contract for such transfer and the urban renewal plan (or such part or parts of such contract or plan as the authority may determine) may be recorded in the land records of the county in such manner as to afford actual or constructive notice thereof.
