Article I. Residential Occupancies
12.04.010 Policy and purpose.

(b) Automatic fire sprinkler systems help to ensure that any fires that occur in residential structures are reasonably within the firefighting capabilities of the DuPont Fire Department; and
(c) Automatic fire sprinkler systems will provide a rational basis for planning public fire protection expenditures by defining the balance between traditional fire protection resources to be supplied by the public and the private sectors while at the same time reducing the costs of traditional fire protection and its related expenditures such as large water mains, fire apparatus turn-arounds, and fire hydrants in newly developing areas. (Ord. 489 § 1, Nov. 9th, 1993).
