A copy of said map, indicating the latest amendments, shall be kept up-to-date in the offices of the Code Enforcement Officer for the use and benefit of the public.

Where district boundaries are indicated as approximately following the center lines of the streets, highways, waterways or railroad rights-of-way or such lines extended, such center lines shall be construed to be such boundaries.

Where such boundaries are indicated as approximately following the property lines of parks or other publicly owned lands, such lines shall be construed to be such boundaries.

Unless otherwise shown, all district boundaries running parallel to streets shall be construed to be set back from the rights-of-way of the distance indicated on the Zoning Map.
