18.80.040 Density transfer.
Calculate density as regulated by TMC 17.15.030(B). Slopes in excess of 25 percent are deducted from available land for purposes of determining permitted density. The lot regulations set forth in TMC 18.80.030(C) apply to the portions of the development within the OSS zone. The following rules apply in particular circumstances:
A. Master-Planned Development. The development of a conceptual master plan (CMP) (as per Chapter 18.215 TMC) accounts for steep slope areas and adjusts densities accordingly to preserve development potential. There is no allowance for additional density transfer.
B. Subdivision. In a standard subdivision the lots outside the OSS zone may be developed at 75 percent of the minimum lot size of the applicable zoning district (e.g., in the RS-5 district 8,000 square feet becomes 6,000 square feet), but only to the extent that permitted density is preserved. This extends the “lot size averaging” principle in TMC 17.15.030(C). [Ord. 817 § 8-3H.140, 2006.]
