§ 9.02.020 Official Districting Map.

The boundaries of the Zoning Districts established by this Ordinance are not included in this Ordinance but are shown on the Official Districting Map of the City, maintained by the City Clerk. The Official Districting Map, together with all legends, symbols, notations, references, zoning district boundaries, map symbols, and other information on the maps, have been adopted by the City Council and are hereby incorporated into this Ordinance by reference, together with any amendments hereafter adopted, as though they were fully included here.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.02.030 Zoning District Boundary Determinations.

A. 
Uncertainty of Boundaries. The following rules shall be employed to determine the boundaries of a district as shown on the Official Districting Map of the City:
1. 
Where a district boundary is indicated as approximately following a street or alley line or parcel line, the centerline of the street or alley or the parcel line shall be the boundary.
2. 
A district boundary that is indicated as approximately following parcel lines, City limits, or extraterritorial boundary lines shall be construed as following such lines, limits, or boundaries.
3. 
When property is unsubdivided or where a district boundary divides a parcel, the location of the boundary, unless it is indicated by dimension, shall be determined by the use of the scale appearing on the Official Districting Map of the City.
4. 
Where any public street or alley is officially vacated or abandoned, the Zoning District regulations applicable to abutting properties shall apply to the former centerline of the vacated or abandoned street or alley.
5. 
Where any private right-of-way or easement of any railroad, railway, transportation, or public utility company is vacated or abandoned, the district regulations applicable to abutting properties shall apply to the former centerline of the vacated or abandoned right-of-way easement.
6. 
The air rights above or the ground rights below any freeway, parkway, highway, street, alley, or easement shall be in the same district as is applicable to the property abutting the freeway, parkway, highway, street, alley, or easement. In cases where a freeway, parkway, highway, street, alley, or easement forms the boundary between districts, the centerline of the right-of-way shall be the boundary.
B. 
Interpretations. In case of any remaining uncertainty, the Director shall determine the location of the district boundary. The Director's decision may be appealed to the Planning Commission in accordance with the procedures in Section 9.37.130, Appeals. Notwithstanding the foregoing, if the district boundary uncertainty arises in the context of a discretionary permit application, then the location of the boundary shall be determined by the decision-making body for that discretionary permit application.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.010 Purpose.

The purpose of this Chapter is to explain how various measurements to which this Ordinance refers shall be calculated.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.020 General Provisions.

For all calculations, the applicant shall be responsible for supplying drawings illustrating the measurements that apply to a project. These drawings shall be drawn to scale and provide sufficient detail, including relevant dimensions, to allow easy verification upon inspection by the Director.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.030 Fractions.

Whenever this Ordinance requires consideration of parking spaces, dwelling units, or other aspects of development or the physical environment expressed in numerical quantities, and the result of a calculation contains a fraction of a whole number, the results will be rounded as follows:
A. 
General Rounding. Fractions of one-half (0.5) or greater shall be rounded up to the nearest whole number, and fractions of less than one-half (0.5) shall be rounded down to the nearest whole number, except as otherwise provided.
B. 
Parking Spaces. Provisions on how to calculate the quantity of parking spaces are detailed in Section 9.28.040, Calculating Off-Street Parking and Loading Spaces.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.040 Measuring Distances.

A. 
Measurements Are Shortest Distance. When measuring a required distance, such as the minimum distance between a structure and a parcel line, the measurement is made at the closest or shortest distance between the 2 objects. Notwithstanding the above, measurements for non-rectilinear parcels shall be made in accordance with Section 9.04.070(A)(2).
B. 
Distances Are Measured Horizontally. When determining distances for setbacks and structure dimensions, all distances are measured along a horizontal plane from the appropriate line, edge of building, structure, storage area, parking area, or other object. These distances are not measured by following the topography or slope of the land.
C. 
Measurements Involving a Structure. Measurements of distance to a structure are measured to the closest exterior wall of the structure. Structures or portions of structures that are entirely underground are not included in measuring required distances.
D. 
Measurement of Vehicle Queuing or Travel Areas. The minimum travel distance for vehicles, such as garage entrance setbacks, is measured down the center of the vehicle travel area. For example, curving driveways and travel lanes are measured along the center arc of the driveway or traffic lane.
E. 
Measuring Radius. When a specified land use is required to be located a minimum distance from another land use, the minimum distance is measured in a straight line from all points along the parcel line of the subject project.
FIGURE 9.04.040: MEASURE DISTANCES
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.050 Measuring Height.

Height shall be the vertical distance from the highest point of any structure to the ground level directly below, except as otherwise provided in this section.
A. 
Measuring Building Height. Building height is the vertical distance at any point in a given plane measured from the Average Natural Grade (ANG), Segmented Average Natural Grade (SANG), or Theoretical Grade (TG). Any of these methodologies can be utilized, except on sloped parcels as described in Section 9.04.050(B), only SANG and TG are authorized.
1. 
ANG. Average Natural Grade is the average elevation of the ground level of the parcel surface as measured at the intersection of the minimum rear and front setback lines (or parcel lines if no setbacks are required) with the minimum side setback lines (or parcel lines if no setbacks are required) of the parcel.
FIGURE 9.04.050.A.1: AVERAGE NATURAL GRADE HEIGHT MEASUREMENTS
2. 
SANG. Segmented Average Natural Grade is measured from the elevation levels of 3 equal segments between the front setback line and rear setback line. The 3 equal segments shall be created by drawing imaginary lines connecting opposite side setback lines (or parcel lines if no setbacks are required) at 1/3 increments of the depth of the parcel from the front setback line to the rear setback line (or parcel lines if no setbacks are required). The elevation for the front 1/3 segment shall be equal to the elevation of the midpoint of the front setback line (or parcel line if no setback is required). The elevation for the rear 1/3 segment shall be equal to the elevation of the midpoint of the rear setback line (or parcel line if no setback is required). The elevation of the middle 1/3 segment shall equal the halfway elevation between the front and rear 1/3 segments.
For parcels larger than 30,000 square feet, Segmented Average Natural Grade can be measured with a maximum of 4 equal segments utilizing the methodology described in this Section 9.04.050(A)(2).
FIGURE 9.04.050.A.2: SEGMENTED AVERAGE NATURAL GRADE HEIGHT MEASUREMENTS
3. 
TG. Theoretical Grade is an imaginary line from the midpoint of the parcel on the front setback line to the midpoint of the parcel on the rear setback line (or parcel lines if no setbacks are required).
FIGURE 9.04.050.A.3: THEORETICAL GRADE HEIGHT MEASUREMENTS
B. 
Measuring Building Height on Sloped Parcels
1. 
Sloped Parcels, Front to Back: On parcels with a grade change of 10% or more between the midpoint of the minimum front setback line and the midpoint of the minimum rear setback line (or parcel lines if no setbacks are required), heights shall be measured either from Theoretical Grade or from Segmented Average Natural Grade.
2. 
Sloped Parcels, Side to Side: On parcels with a grade change of 10% or more between the midpoint of the minimum side setback line and the midpoint of the opposite side setback line (or parcel lines if no setbacks are required) AND with a grade change of a greater percentage than the slope from the midpoint of the minimum front setback line and the midpoint of the minimum rear setback line, heights shall be measured from the Theoretical Grade line between the midpoint of the minimum side setback line and the midpoint of the opposite side setback line or from Segmented Average Natural Grade.
C. 
Measuring First Story Street Wall Height. Street wall height is measured from finished grade at all points along the sidewalk to all points of the first story wall directly above each point along the sidewalk.
D. 
Measuring Fence, Wall, and Hedge Height. The height of any fence, wall, or hedge shall be measured from the lowest finished grade adjacent to either side of the fence, wall, or hedge. The height shall be measured in a continuum at each point along the fence, wall, or hedge. In the case of fences, walls, or hedges that are parallel to and within 5 feet of a public sidewalk or other public way, grade shall be the elevation of the closest point on the sidewalk or public way.
FIGURE 9.04.050.D.1: MEASURING HEIGHT OF FENCES OR WALLS
1. 
Measuring the Height of Fences on Retaining Walls. Notwithstanding the above, the height of a fence that is on top of a retaining wall is measured from the lowest existing grade point within a 3 foot radius of any point on such fence to the highest point of the fence on the highest side of the wall. Any fence or railing required to comply with minimum height in applicable Building Code requirements is permitted.

Mezzanines, basements, and attics shall not be counted as stories.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.070 Measuring Parcel Width and Depth.

A. 
Parcel Width.
1. 
Rectilinear Parcels. Parcel width shall be determined by measuring the distance between side parcel lines. The measurement shall be determined by the length of a straight line drawn at right angles to the side parcel lines and parallel with both the front and rear parcel lines (see illustration A).
2.

§ 9.04.090 Determining Floor Area Ratio in Nonresidential Zoning Districts.

Floor area ratio (FAR) is the ratio of the floor area, as specified in Section 9.04.080, excluding the areas described below, of all principal and accessory buildings on a site to the site area. To calculate FAR, floor area is divided by site area and typically expressed as a decimal. For example, if the floor area of all buildings on a site totals 20,000 square feet, and the site area is 10,000 square feet, the FAR is expressed as 2.0. For parcels containing more than one zoning designation pursuant to Section 9.21.040, the maximum floor area shall be calculated according to the parcel area within each Zoning District and the corresponding floor area ratio for the district.
A. 
Areas Excluded from Floor Area Ratio. The following areas shall be excluded when calculating FAR in nonresidential zoning districts:
1. 
Floor area devoted to basements;
2. 
Unenclosed decks, balconies, porches, outdoor dining areas permitted pursuant to Section 9.31.200, Outdoor Dining and Seating on Sidewalks, provided the dining areas have not more than a 42-inch high barrier surrounding the dining area and is visible from the public right-of-way, and other open spaces, and outdoor space permitted pursuant to Section 9.31.199, Outdoor Commercial Uses on Private Property.

Floor area ratio (FAR) is the ratio of the floor area, as specified in Section 9.04.080, of all principal and accessory buildings on a site to the site area and subject to the inclusions and exclusions below. To calculate FAR, the floor area is divided by site area and typically expressed as a decimal. For example, if the floor area of all buildings on a site totals 5,000 square feet, and the site area is 10,000 square feet, the FAR is expressed as 0.50. For parcels containing more than one zoning designation, pursuant to Section 9.21.040, the maximum floor area shall be calculated according to the parcel area within each Zoning District and the corresponding floor area ratio for the district.
A. 
Areas Included in Floor Area Ratio. The following areas shall be included when calculating FAR in residential zoning districts:
1. 
Areas defined as floor area in Section 9.04.080;
2. 
Areas with ceiling heights exceeding an upper story floor line by 7 feet or more shall count towards each subject upper story.

a. 
Enclosed on at least three sides; and
b. 
Covered by a roof that is less than 50% open to the sky; and
5. 
Areas enclosed on more than two sides below an upper story or accessory building.
B. 
Areas Excluded from Floor Area Ratio. The following areas shall be excluded when calculating FAR in residential zoning districts:
1.

§ 9.04.110 Determining Parcel Frontage.

A. 
Corner Parcel. The front of a parcel is the narrowest dimension of the parcel with street frontage. For corner parcels with equal street frontage dimensions, the front of the parcel is the street frontage that is consistent with the prevailing street frontage orientations along the block where the corner parcel is located.
B.

§ 9.04.120 Determining Residential Density.

The maximum number of dwelling units allowed on any site shall be determined by dividing the area of the site, including ½ of the area of an abutting rear alley, by the minimum number of square feet for each dwelling unit as required in the Zoning District in which the site is located. However, in the R2, R3, and R4 districts, no portion of the rear alley shall be used to calculate the area of the site except for 100% Affordable Housing Projects.
(Added by Ord. No. 2486CCS §§ 1, 2, adopted June 23, 2015)

§ 9.04.130 Determining Setbacks.

A line defining a required setback is parallel to and at the specified distance from the corresponding property line. For non-rectilinear parcels, setbacks shall be determined in accordance with the standards for measuring parcel width and depth in Section 9.04.070. The following special regulations for determining setbacks apply when a parcel abuts an alley or walk street.
A. 
Side Parcel Line Abutting an Alley. If a side parcel line abuts an alley, the setback shall be considered an interior side setback rather than a street side setback.
B. 
Rear Parcel Line Abutting an Alley. Where a rear parcel line abuts an alley, the rear setback shall be measured from the center line of the alley.
C. 
Rear Parcel Line Abutting a Walk Street. Where a rear parcel line abuts a walk street, the rear setback shall be measured from the center line of the walk street.
