Health & Saf. Code, § 33036

It is further found and declared that:

(a) Such conditions of blight tend to further obsolescence, deterioration, and disuse because of the lack of incentive to the individual landowner and his inability to improve, modernize, or rehabilitate his property while the condition of the neighboring properties remains unchanged.

(b) As a consequence the process of deterioration of a blighted area frequently cannot be halted or corrected except by redeveloping the entire area, or substantial portions of it.

(c) Such conditions of blight are chiefly found in areas subdivided into small parcels, held in divided and widely scattered ownerships, frequently under defective titles, and in many such instances the private assembly of the land in blighted areas for redevelopment is so difficult and costly that it is uneconomic and as a practical matter impossible for owners to undertake because of lack of the legal power and excessive costs.

(d) The remedying of such conditions may require the public acquisition at fair prices of adequate areas, the clearance of the areas through demolition of existing obsolete, inadequate, unsafe, and insanitary buildings, and the redevelopment of the areas suffering from such conditions under proper supervision, with appropriate planning, and continuing land use and construction policies.
