   2.   Official Zoning Map:
      A.   Incorporation of Map:
         (1)   The location and boundaries of zoning districts are shown upon the Official Zoning Map for Boise City.
         (2)   The Official Zoning Map shall be maintained by and copies will be obtained through the Planning and Development Services Department and shall be made available for review and inspection. A digital version of the Official Zoning Map will be made available through the City's website.
      B.   Rules for Interpretation of Boundaries: Wherever any uncertainty exists as to the boundary of a district, the following rules shall apply:
         (1)   Where any boundary line is indicated as following a street, alley, waterway, railroad right-of-way or public way, it shall be construed as following the centerline thereof.
         (2)   Where a boundary line is indicated as approximately following a lot line/property line, such lot line/property line shall be construed to be the boundary line.
      C.   Amendments to the Official Zoning Map: Changes to the boundaries of any zoning district require an amendment to the Official Zoning Map per Section 11-05-05.4.I, Zoning Map Amendment (Rezoning, including Planned Unit Development).
   3.   Organization Of This Chapter:
      A.   Base Zoning Districts:
         (1)   Content: Sections 11-02-02 through 11-02-06 follow a common structure for each base zoning district in Boise. Each district includes the following:
            (a)   A purpose statement describing the intended character of the district.
            (b)   Chapters and sections of the Code that contain additional requirements for development in the district.
            (c)   The basic lot and building standards that apply to development within that district such as lot size, setbacks, building height, and building form.
            (d)   Other standards that apply to that district (as opposed to a specific use or type of development).
         (2)   Graphics:
            (a)   Each base zoning district is accompanied by at least one graphic depicting how the lot and building standards apply to lots and building forms within the respective district. Such graphics and illustrations are intended to represent the general character of development within the district but are not intended to identify specific projects or locations within that district.
            (b)   The graphics and illustrations are not regulatory and are not to be compared to the visual look of a proposed development.
            (c)   The graphics do not reflect all standards from the Code that may apply to a project and are intentionally conceptual versus detailed.
            (d)   Where an illustration is inconsistent with the respective table of lot and building standards or other text within this Code, the standards in the table and text shall apply.
      B.   Overlay Districts:
         (1)   In addition to the underlying base zoning district, some lands may be designated in one or more overlay districts. Where a property is assigned an overlay district, both sets of regulations apply, with those of the overlay controlling in case of conflict. An overlay district may apply additional requirements or allow exceptions to the standard regulations of the base zoning district. Each overlay district title ends with "-O" (for overlay).
         (2)   Section 11-02-07 identifies the overlay districts and establishes the purpose and applicable standards that modify the requirements of the underlying base zoning district. (Ord. 27-23, 7-18-2023, eff. 12-1-2023; amd. Ord. 43-23, 12-5-2023)
11-02-02: RESIDENTIAL ZONING DISTRICTS:
   1.   R-1A Residential: Large Lot:
      A.    Purpose: The R-1A district is intended for predominant ly residential uses on large "estate" style lots that allow low-density developmen t and preserve a character in which homes are separated by relatively large yards.
      B.   Cross-References to Other Applicable Code Sections: All development shall comply with all applicable sections of this Code. Cross-references to some of the key sections are provided below.

This requirement is not met by ground floor parking areas, storage areas, utility facilities, or stairwells that are not accessible from the street frontage.
         (5)   Building Design: Enhanced building design through compliance with more of the Citywide or Downtown Design Standards and Guidelines (as applicable) or performance of such design standards and guidelines at a higher level of quality or visual interest, as determined by the Planning Director.
