Louisiana Act 234

Granted authority to police juries to regulate subdivisions and layouts of streets and parks. However, there was no requirement or mention of planning before deciding on regulations.

The police juries were granted a measure of planning authority in 1928. The statute does not provide for any separate planning agency or other administrative machinery but it does empower a police jury to legislate broadly with respect both to the laying out and modification of streets, parks and other public improvements and to the private platting and subdividing of land.

Housing and Community Development Act of 1974

When Congress passed the HCD Act of 1974, it broke down the barriers of prevailing practice - where under separate categorical programs, the Federal Government had made the decisions about every community development project undertaken by cities.

CDBG merged 7 categorical programs into a block of flexible community development funds distributed each year by a formula that considers population and measures of distress including poverty, age of housing, housing overcrowding, and growth lag.
