Incompetence

New zoning ordinance was written without thorough research.

SECTION 9 SEVERABILITY
If any section, clause, provision, or portion of this Ordinance is adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this Ordinance shall not be affected thereby.

This is absurd, let me explain by using the same logic, but inverting the language:
“If any portion of this Ordinance is not unconstitutional, that part will remain.”
The author does not even know if his ordinance is constitutional.

SECTION 10 ABROGATION AND GREATER RESTRICTIONS

It is not intended by this Ordinance to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this Ordinance imposes greater restrictions, the provisions of this Ordinance shall prevail. All other ordinances inconsistent with this Ordinance are hereby repealed to the extent of the inconsistency only.

More of the author’s lack of knowledge and logic. Simplifying the language:

“I did not check to see if this ordinance conflicts with others, so the others no longer matter.”
