ARTICLE I. STATUTORY AUTHORIZATION
The Legislature of the Commonwealth of Pennsylvania has, by the passage of the Pennsylvania Flood Plain Management Act of 1978, delegated the responsibility to local governmental units to adopt floodplain management regulations to promote public health, safety, and the general welfare of its citizenry. Therefore, the Council of Darlington Borough does hereby order as
follows. ARTICLE II. GENERAL PROVISIONS Section 2.01 Intent The intent of this Ordinance is to:
- A. Promote the general health, welfare, and safety of the community.

- C. Minimize danger to public health by protecting water supply and natural drainage.
- D. Reduce financial burdens imposed on the community, its governmental units, and its residents, by preventing excessive development in areas subject to flooding.
- E. Comply with federal and state floodplain management requirements.
Section 2.02 Applicability
- A. It shall be unlawful for any person, partnership, business or corporation to undertake, or cause to be undertaken, any construction or development anywhere within the Borough of Darlington unless a Permit has been obtained from the Floodplain Administrator.
- B. A Permit shall not be required for minor repairs to existing buildings or structures.
Section 2.03 Abrogation and Greater Restrictions
This ordinance supersedes any other conflicting provisions which may be in effect in identified floodplain areas. However, any other ordinance provisions shall remain in full force and effect to the extent that those provisions are more restrictive. If there is any conflict between any of the provisions of this Ordinance, the more restrictive shall apply.
Section 2.04 Severability
If any section, subsection, paragraph, sentence, clause, or phrase of this Ordinance shall be declared invalid for any reason whatsoever, such a decision shall not affect the remaining portions of the Ordinance, which shall remain in full force and effect, and for this purpose the provisions of this Ordinance are hereby declared to be severable.
