Section 12
SEC. 12. In computing the cost of the lots to be leased or sold to individuals under the authority of the next preceding section, the following expenditures may be taken into account: Aggregate cost of acquisition of the land from the private owner, including expenses of the expropriation proceedings and appraisals; Cost of subdivision survey; Cost of development expenses for filling, construction of streets, curves, and side-walks, drainage, clearing, and other public works which enhance the value of the land; and Cost of improvement acquired incidental to the acquisition of the land. If the land acquired be of varying character and value, the aggregate cost of acquisition shall be distributed equitably by the Board of Directors among the various sections or lots. The cost of areas set aside for streets, parks, community centers, and other public uses primarily for the benefit of the individual lots shall likewise be equitably allotted to the cost of the lots.
