R, Residential Districts.
All residential zoning district names begin with the letter “R,” which is a short-hand reference to “residential.” The second letter of all “R” district map symbols (other than the RMHP district) provides an indication of the primary characteristic of the district —”S” for single-dwelling, “D” for duplex, and “M” for multi-dwelling. Residential districts that end with a number provide a short-hand reference to the maximum density allowed in the district (expressed in terms of the number of dwelling units allowed per acre of land area). The RM-15 district, for example, is a residential zoning district that is primarily intended for multi-unit building types, with a maximum allowed density of 15 units per acre.
C, Commercial Districts.
All commercial zoning district names begin with the letter "C," which is a short-hand reference to "commercial." Subsequent letters of the commercial district map symbols are abbreviations indicating the general character of the district or simply abbreviations of the full district name. Numbers, where used, are intended to identify the relative intensity of similar districts. Thus, the CN-1 district name is intended to denote a commercial zoning district, with a neighborhood-oriented or neighborhood-serving character that is less intensive than its CN-2 counterpart.
M, Manufacturing Districts.
All manufacturing zoning district names begin with the letter "M," which is a short-hand reference to "manufacturing." Numbers that follow the letter "M" indicate the relative intensity of uses and/or development allowed within the districts, with "M-1" indicating a manufacturing district that is less intensive than the M-2 district.
Conflicts. If a conflict arises between the regulations in Chapter 50 and those in Appendix A, the regulations of Chapter 50 take precedent unless otherwise approved by the City Planner.
