DIVISION 4. - SOURCE WATER PROTECTION AREA ORDINANCE—BRANDYWINE CREEK, UPSTREAM OF DRINKING WATER INTAKE AND RACEWAY


Sec. 48-437.1. - Purpose and intent.

(a)

Pursuant to the Delaware Source Water Protection Law of 2001, 7 Del. C. §§ 6081-6084, and consistent with the city's ongoing efforts to improve surface water quality, the city, with the assistance of the Delaware Department of Natural Resources and Environmental Control (DNREC) delineated a Source Water Protection Area (SWPA) within the city limits for the Brandywine Creek, the city's source of drinking water, and created a SWPA Map which was adopted as part of the city's comprehensive plan. Parcels within the SWPA shall be subject to this division which is designed to protect the SWPA, a critical area, from activities and substances that may harm water quality and subtract from overall water quantity. The SWPA includes two sub-categories with more stringent water quality and quantity protection requirements: (1) SWPA Subcategory A - Erosion Prone Slopes; and, (2) SWPA Subcategory B - 200 Foot Creek Buffer from the bank of the Brandywine Creek. Tax parcels located within the SWPA must meet the requirements of the relevant zoning district and must also comply with the SWPA requirements and prohibitions. If there is an inconsistency between the zoning district and SWPA requirements, the higher standard shall govern, consistent with City Code section section 48-4

(b)

The SWPA map may be amended from time to time as deemed scientifically appropriate by the department of public works and DNREC and as approved by the planning commission and adopted by city council.

(c)

For parcels located within the SWPA any application for new development to the city, county, state or the federal government triggers applicability of this division.
