11-2-3: - RULES FOR MEASUREMENT

The purpose of this Section is to explain how various measurements referred to in this Ordinance are to be calculated.

A.

Applicant's Responsibility. 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 of sufficient detail to allow easy verification upon inspection by the Planning Director or designee.

B.

Fractions. Whenever the result of a required arithmetical calculation, using a stated mathematical formula or ratio, contains a fraction of a whole number, fractions of ½ or greater shall be rounded up to the nearest whole number and fractions of less than ½ shall be rounded down to the nearest whole number. This rule shall be superseded when an alternate rule for rounding is specified by the same chapter of this Ordinance that describes the requirement.

C.

Measuring Distances.

1.

Measurements are Shortest Distance. When measuring a required distance, such as the minimum distance between a structure and a lot line, the measurement is made at the closest or shortest distance between the two objects.

2.

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.

3.

Measurements Involving a Structure. Measurements involving a structure, such as required yards, separations between buildings, or distances between structures, are made to the closest support wall, post or column of the structure. Structures or portions of structures that are entirely underground are not included in measuring required distances.

4.

Measurement of Vehicle Stacking or Travel Areas. Measurement of a minimum travel distance for vehicles, such as garage entrance setbacks and stacking lane distances, are 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.

5.

Measurement from an Intersection. Measurements involving a distance from an intersection are measured in a straight line from all points along the lot line of the subject property to the nearest edge of right-of-way.

FIGURE 11-2-3.C: MEASURING DISTANCES

FIGURE 11-2-3.C: MEASURING DISTANCES

D.

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 lot line of the subject project. In the event the lot line is curved, the separation radius shall also curve in a similar manner to maintain the specified minimum radius distance. The starting point for the measurement shall be the closest point on the outermost property line for the lot or development site of the protected use, including multiple parcel development sites acting as a campus, or sharing parking, access aisles and other appurtenant shared facilities, such as group development sites. The distance shall be measured to the outside nearest wall of the building intended to house the proposed use.

E.

Measuring Height.

1.

Measuring Building Height. Building Height is measured from the average level of the highest and lowest point of that portion of the lot covered by the building to the mean point between the plate line (where the vertical wall attaches to the roof) and the highest point of the roof ridge, or to the top of a parapet wall or flat roof.

FIGURE 11-2-3.E.1: MEASURING HEIGHT GABLE OR HIP ROOF

FIGURE 11-2-3.E.3: MEASURING HEIGHT MANSARD or GAMBREL ROOF

2.

Measuring Height of Other Structures. The height of other structures such as fences is the vertical distance from the ground level immediately under the structure to the top of the structure. Special measurement provisions are also provided below:

a.

Measuring the Height of Fences on Retaining Walls. The height of a fence that is on top of a retaining wall is measured from the ground level on the highest side of the fence and wall.

b.

Measuring the Height of Decks. Deck height is determined by measuring from the ground to the top of the floor of the deck.

FIGURE 11-2-3.E.4: MEASURING HEIGHT DECKS AND FENCES ON RETAINING WALLS

FIGURE 11-2-3.E.4: MEASURING HEIGHT DECKS AND FENCES ON RETAINING WALLS

F.

Measuring Lot Width and Depth.

1.

Lot Width. Lot width is the horizontal distance between the side lot lines, measured at right angles to the lot depth. Minimum lot width is measured perpendicular to the lot depth at both the front and rear setbacks, based on the applicable zoning district applied to the property.

2.

Lot Depth. Lot depth is measured along an imaginary straight line drawn from the midpoint of the front property line of the lot to the midpoint of the rear property line or to the most distant point on any other lot line where there is no rear lot line.

FIGURE 11-2-3.F: MEASURING LOT WIDTH AND DEPTH

FIGURE 11-2-3.F: MEASURING LOT WIDTH AND DEPTH

G.

Determining Average Slope. The average slope of a parcel is calculated using the following formula: S = 100(I) (L)/A, where:

1.

S = Average slope (in percent).

2.

I = Contour interval (in feet).

3.

L = Total length of all contour lines on the parcel (in feet).

4.

A = Area of subject parcel (in square feet).

H.

Determining Floor Area.

1.

Gross Floor Area. As defined in Chapter 87, includes the floor area of garages, carports, ventilation shafts, shafts, elevators, stairways, corridors, bathrooms, mechanical rooms, closets, storage and equipment storage rooms, open porches, balconies, courts, atriums, lobby areas, basements, and attics.

2.

Floor Area (Net Floor Area). As defined in Chapter 87, excludes the floor area of garages, carports, ventilation shafts, shafts, elevators, stairways, corridors, bathrooms, mechanical rooms, closets, storage and equipment storage rooms, open porches, balconies, courts, atriums, lobby areas, basements, and attics.

I.

Determining Floor Area Ratio. The Floor Area Ratio (FAR) is the ratio of the floor area of all principal and accessory buildings on a lot to the lot area. To calculate FAR, floor area is divided by lot area, and typically expressed as a decimal. For example, if the floor area of all buildings on a lot totals 20,000 square feet, and the lot area is 10,000 square feet, the FAR is expressed as 2.0.

Figure 11-2-3.1: Determining Floor Area Ratio

Figure 11-2-3.1: Determining Floor Area Ratio

J.

Determining Building Coverage. Building coverage is the ratio of the total footprint area of all structures on a lot to the net lot area, typically expressed as a percentage. The total footprint of all principal and accessory structures, including garages, carports, covered patios, and roofed porches, is used to calculate building coverage; except the calculation excludes the following areas:

1.

Decks, patio slabs, landings, balconies and stairways (less than 6-feet in height), when unenclosed, unroofed, and/or uncovered;

2.

Eaves and roof overhangs projecting up to two-and-a-half feet from a building wall;

3.

Trellises and similar structures that do not have solid roofs;

4.

Swimming pools and hot tubs that are not enclosed in roofed structures or decks; and

5.

One small, non-habitable accessory structure under 120 square feet and under seven feet high. All other accessory structures are included in building coverage.

FIGURE 11-2-3.J: DETERMINING BUILDING COVERAGE

FIGURE 11-2-3.J: DETERMINING BUILDING COVERAGE

K.

Determining Lot Frontage.

1.

Corner Lot. The front of a lot is the narrowest dimension of the lot with street frontage.

2.

Through Lot (Double Frontage Lot). The front yard borders the street primarily used as frontage by neighboring lots. If both street fronts of the Through Lot are adjacent to lots that also front onto the same street, both street fronts of the though lot shall be considered as required front yards for the purpose of determining building setbacks and fence height requirements.

L.

Determining Setbacks for Yards. A setback line defining a required yard is parallel to and at the specified distance from the corresponding front, side, or rear property line. The following special regulations for determining yards apply when a lot abuts a proposed street or alley:

1.

Yards Abutting Planned Street Expansions. If a property abuts an existing or proposed street for which the existing right-of-way is narrower than the right-of-way ultimately required for the street as determined by the City Council through the latest adopted transportation and/or street plan, the required setback shall be established from the future right-of-way rather than the property line. In the event that the street is not listed under the latest adopted transportation plan, the street width shall be determined based on the street classification and right-of-way width requirements specified in Title 9, Chapter 6 of the Mesa City Code.

FIGURE 11-2-3.L: DETERMINING SETBACKS

FIGURE 11-2-3.L: DETERMINING SETBACKS

2.

Yards on Alleys.

a.

If a side lot line abuts an alley, the yard shall be considered an interior side yard rather than a corner side yard.

b.

In computing the minimum yard for any lot where such yard abuts an alley, no part of the width of the alley may be considered as part of the required yard except rear yards in RS districts, as specified by Section 11-5-3(D).

M.

Measuring Signs. The height of signs is measured in the same method as the height of other structures. Calculation of sign area is described in Article 5, Signs.

(Ord. No. 5592, § 1, 12-1-20; Ord. No. 5593, § 1, 12-1-20; Res. No. 12269, § 1, 9-23-24; Ord. No. 5883, § 3, 10-7-24)

11-2-4: - RULES OF INTERPRETATION

The Zoning Administrator shall interpret any provision or any method of measurement not expressly identified in this Chapter, and provide clarification and determination of these rules and their application to a specific site. The Zoning Administrator shall maintain a record of these interpretations.

The Particular Controls the General

Whenever a general provision in a rule shall be in conflict with a particular provision in the same or another rule, the two shall be construed, if possible, so that effect may be given to both. If the conflict between the two provisions is irreconcilable, the particular provisions shall prevail and shall be construed as an exception to the general provision, unless the general provision shall be promulgated later and it shall be the manifest intention of the Supreme Court that such general provision shall prevail.

C.

Community Character Designators. Recognizing that not all areas of the City are the same, two community character designators have been established to enhance some multi-residence, commercial and mixed-use districts. These designators are combined with the base district abbreviations in order to establish area-specific development standards according to the intended development character.

1.

Urban (-U). This designation is intended for areas with an urban character, where buildings are built close to the street and sidewalk to provide a close relationship between pedestrians and shops. Site and building design standards will reinforce this character and require treatments that provide an interesting, safe and comfortable pedestrian environment. This designation may apply to some areas where a few auto-oriented uses exist, but where creating, restoring, or maintaining a pedestrian character is called for in the General Plan, a Sub-Area Plan or other City policy.

2.

Auto-Oriented (-A). This designation is intended for areas that provide for easy automobile access. Examples include Large Commercial Development buildings that may be located at the back or side of a site with parking in front. Standards are intended to mitigate the impact of the parking lots and buffer adjacent residential areas.

3.

Associated Districts. The districts that may utilize the character designators are as follows:

11-3-2: - OFFICIAL ZONING MAP AND DISTRICT BOUNDARIES

The boundaries of the zones established by this Ordinance are not included in this Ordinance but are shown on the Official Zoning Map maintained by the City. The Official Zoning Map, together with all legends, symbols, notations, references, zoning district boundaries, map symbols, and other information on the maps, has been adopted by the City Council and are hereby incorporated into this Ordinance by reference, together with any amendments previously or hereafter adopted, as though they were fully included here.

A.

Uncertainty of Boundaries. Where uncertainty exists as to the boundaries of any district shown on the Official Zoning Map, the following rules shall apply:

1.

Boundaries indicated as approximately following property or land parcel lines, street or alley rights-of-way, city limits, or extraterritorial boundary lines shall be construed as following such lines, limits or boundaries.

2.

In the case of un-subdivided property or where a district boundary divides a lot and no dimensions are indicated, the following shall apply:

a.

Lots Greater than One Acre. The location of such boundary shall be determined by the use of the scale appearing on the Official Zoning Map.

b.

Lots Less than One Acre. The lot shall be deemed to be included within the zone which is the more restrictive.

3.

In the case of any remaining uncertainty, the Zoning Administrator shall determine the location of boundaries.

4.

Where any public street or alley is officially vacated or abandoned, the land underlying the street or alley will be added to abutting lots as required by state law. The regulations that applied to the abutting parcel or parcels before the vacation or abandonment shall apply to the entire new larger parcel or parcels that result from such vacation or abandonment.

5.

Where any private right-of-way or easement of any railroad, railway, transportation or public utility company is vacated or abandoned the land underlying the right-of-way or easement shall be added to abutting lots as required by state law. If the abandoned or vacated property is unclassified, the property shall be automatically classified as being in the same zone of the abutting land to which it is added.

B.

Conditions. Conditions imposed by special ordinance in conjunction with amendments to the Zoning Map are referenced by separate files maintained in the Planning Division and are made a part of the Zoning Map.
