A. Structures and uses established and legally existing on or before January 1, 1996, are exempt from a system development charge, except sewer charges, to the extent of the structure or use then existing and to the extent of the parcel of land as it was constituted on that date. Structures and uses affected by this subsection shall pay the sewer charges pursuant to the terms of Ordinance 91-7 of the Bear Creek Valley Sanitary Authority (BCVSA) upon the receipt of a permit to connect to the sewer system.

B. Additions to dwellings that do not constitute the addition of a dwelling unit, as defined by the Oregon State Structural Code and/or the Oregon Residential Specialty Code, are exempt from all portions of the system development charge.

C. An alteration, addition, replacement or change in use that does not increase the parcel or structure’s use of the public improvement facility is exempt from all portions of the system development charge.

D. Any existing building development or installation of water meters that took place prior to the city’s adoption of system development charges on November 15, 1995, cannot be used in the calculation of credits when uses on the property change or additional development takes place. However, when calculating the impervious surface for storm water SDCs or the trip generation for transportation SDCs, consideration will be given to existing uses on the property. The method of calculation is contained in the respective methodology ordinances. [Ord. 792 § 9; Ord. 725 § 9.]
