Objectively, there are several challenges and situations where unintended consequences will create inequity across property lines. Property evolution is inevitable, and it is fair to consider not only what is there today but what might be added in the future. Overall Notes: - This section is overly complex making it difficult to understand at a high level, which can lead to confusion and otherwise mask possible inequalities, especially with each speciflc zoning designation. - Commercial lots, especially in the core, must be able to evolve to for the health of downtown. - These standards appear to presume that “subject lots” will have large mass buildings on wide frontages, which is not always the case. o Narrower lots are especially unfairly restricted and could create odd development patterns - The subject lot should have the same minimum ability to develop what the abutting lot zoning allows – before transition restrictions apply. Transition Types (1A / 1B / 2A / 2B): - Forcing extra setbacks and designating additional landscaping buffers exacerbates the inequality factor. Buffers can happen on both sides of property line. 1b & 2b (extra landscape setbacks on the subject lot) should be eliminated for fairness and clarity. Diagram Notes: - Dimension designations of A & B are confusing. Use X & Y. - Trees should be shown larger (to scale for mature conditions). - Verify scale of fioors and buildings in all existing diagrams We would like to request that the attached edits to the transition section. Additionally, please see the attached diagrams for more context and possible development scenarios.

Rules for Type 1a and Type 1b: (1) Where a lot is adjacent to an RA or RB district, all setback distances must be increased by 3 feet. (2) For subject lots facing RA and RB districts, and fronting a right-of-way less than 60 feet wide, the upper level(s) of a building must be stepped back from the front property lines according to the height stepback standard. f. Rules for all transition types. (1) Required transition types must be located along side and rear lot lines extending inward to the subject property, or front property lines where the street right-of-way width is less than 60 feet. Transition types cannot extend into, or be located within, any portion of an existing street right-of-way. (2) No buildings or structures, except for walls or fences, are allowed in the transition setback area. (3) Except when abutting an alley, no parking area, driveway or fire lane is allowed in the transition setback area. (4) Required landscaping must meet 38.540. 4. Measurement. a. All building setbacks are measured from the lot line - see 38.260.060. b. When the entire building is set back from the lot line at least 22 feet, the building can go straight up - no step back is required. Figure 38.260.070-1. Horizontal transition measurement.
