SECTION 2. 
The provisions of Title 11, insofar as they are substantially the same as ordinance provisions previously adopted by the city relating to the same matter, shall be construed as restatements and continuations, and not as new enactments.

Such specific plan shall be consistent with and implement the general plan. A specific plan shall provide for the type, location and density of land uses, the development standards and regulations, including, but not limited to, height, setback, landscaping, and parking requirements, the purpose, type, location and extent of public improvements and facilities, and any other matters considered appropriate or necessary.
B. 
With respect to any property for which a specific plan has been adopted, no tentative tract map or tentative parcel map may be approved nor may any permit license or other entitlement for use be granted or issued unless such map, permit, license or other entitlement for use is consistent with such specific plan.
C. 
The city council, after adopting a specific plan, may impose a specific plan fee upon persons seeking governmental approvals which are required to be consistent with the specific plan. The fees shall be established so that in the aggregate, such fees (as estimated) defray, but do not exceed the cost of preparation, adoption, and administration of the specific plan, including costs incurred pursuant to Division 13 (commencing with Section 21000) of the Public Resources Code. As nearly as can be estimated, the fee charged shall be a prorated amount in accordance with the applicant's relative benefit derived from the specific plan.

b. 
Section 11.5.15.040C of Title 11 is amended to read as follows:
"11.5.15.040 C. Special Factors in Determining Specific Plan Standards. Prior to approving a specific plan or an amendment to a specific plan, particular care must be exercised in the establishment of building height development standards for each specific plan under the provisions of Section 11.3.25.010A. Factors to be carefully weighed shall include, but not be limited to, the planning district in which the specific plan is to be located, the former zoning of the specific plan site, height of existing buildings immediately surrounding the specific plan site and the effect of the building height on the areas surrounding the specific plan site. No building within the SPR Zone shall exceed a height of 39 feet, except for nonhabitable architectural features of any proposed buildings, in that portion of the city known as the Coastal Zone as defined by the California Coastal Act, or north of the San Diego Freeway, except such portions thereof which are zoned LM, Light Manufacturing, on October 14, 1985.

Further, the Council directs the City Clerk to make any necessary clerical change to any adopted Specific Plan to conform any reference to zoning designations in the Specific Plan to any new Zoning designation as described in Title 11 and on the zoning map. Such clerical changes will not confer additional rights or obligations on property owners.
SECTION 8. 
The City Council hereby adopts Zone Change 10-2 (Zoning Map).

(Ord. 1598)

11.1.15.020 Measuring Distances.

A. 
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. See Figure 11.1.15.020.A: Shortest Distance.
Figure 11.1.15.020.A Shortest Distance
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. See Figure 11.1.15.020.B: Horizontal Measurement.
Figure 11.1.15.020.B Horizontal Measurement

Structures or portions of structures that are entirely underground are included in measuring required distances. See Figure 11.1.15.020.C.1: Measurements Involving a Structure, and Figure 11.1.15.020.C.2: Architectural Projections into Setbacks.
Figure 11.1.15.020.C.1 Measurements Involving a Structure
Figure 11.1.15.020.C.2 Architectural Projections into Setbacks
(Ord. 1598; Ord. 1611)

11.1.15.025 Measuring Height.

A. 
General. The height of a structure shall be measured vertically from the average level of the highest and lowest finished grade of the ground covered by the structure to the highest point of the structure or to the peak of a gable, pitched, mansard or hipped roof or to the finished roofline of a flat roof or top of a parapet required by California Building Code.
1. 
Exceptions for Accessory Building Features. The following listed building features may be erected to a maximum height as follows:
a. 
Chimneys. Two feet above roofline as per California Building Code.
b. 
Flagpole. Up to 20 feet (10 feet above roofline maximum).
c. 
Antennae. Up to 10 feet above roofline. Ground antennae to a maximum of 40 feet if located in the rear yard adjacent to the main structure.
2. 
Exception for Surfside. Maximum building height for residential structures, including accessory dwelling units, shall be measured pursuant to Section 11.2.05.015.A.3: Building Height Limit.
B. 
Measuring the Height of Buildings Located Near Retaining Walls. If any portion of a building lies within 5 horizontal feet of an above-ground retaining wall, and the base of the retaining wall is at a lower elevation than the building, the height of the building shall be calculated from the base of the retaining wall (at the lower of natural or finished grade) rather than from the base of the building wall. See Figure 11.1.15.025.B: Measuring the Height of Buildings Near Retaining Walls.
Figure 11.1.15.025.B Measuring the Height of Buildings Near Retaining Walls
C. 
Measurement of Fence or Wall Height.
1. 
Determination of Height. The height at the property line shall be measured from the owner's side of the fence or wall. A joint fence or wall on the property line may be measured from either side of the fence or wall. In the case of a joint fence or wall where there is a difference in the ground level between 2 adjoining parcels of less than 2 feet, the height of a fence or wall constructed along the property line shall be determined by using the finished grade at the base of the fence or wall on the highest parcel.
Figure 11.1.15.025.C Determination of Property Line Fence Height
2. 
Determination—Ground Level Difference More than 2 Feet. When there is a difference in the ground level between 2 adjoining parcels of 2 feet or more, the height of a fence or wall shall be determined by the provisions of subsection D, Measuring the Height of Combined Fences and Retaining Walls.
D. 
Measuring the Height of Combined Fences and Retaining Walls. When a fence is constructed on top of or within 1 foot of the face of an above-ground retaining wall greater than 2 feet in height, and located in a required yard, the height of the fence shall be measured from the top of the fence to the midpoint height of the retaining wall, excluding the uppermost 2 feet of the retaining wall.
Figure 11.1.15.025.D Fences on Top of Retaining Walls
E. 
Measuring the Height of Decks. Deck height is measured from grade to the top of the floor of the deck if there is no rail or if the rail walls are more than 50% open, and from the ground to the top of the rails for all other situations.
(Ord. 1598; Ord. 1699; Ord. 1721, 11/10/2025)

11.1.15.030 Measuring Lot Width and Depth.

A. 
Lot Width. Lot width is the mean of the distances between the side lot lines as drawn at right angles to the lot depth line at points 20 feet from its front and back.
B. 
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. Where no lot line is within 45 degrees of being parallel to the front lot line, a line 10 feet in length within the lot, parallel to and at the maximum possible distance from the front lot line, will be deemed the rear lot line for the purpose of establishing setbacks and measuring rear yard depth. Refer also to Section 11.6.05.010: Definitions of Specialized Terms and Phrases; Lot Line Types: Rear Lot Line, and Figure 11.6.05.010.L.5: Irregular Lots: Determining Rear Lot Line.
Figure 11.1.15.030 Measuring Lot Width and Depth
(Ord. 1598)

11.1.15.035 Measuring Tree Diameter.

A. 
Existing Trees. Existing trees are measured at a height of 4.5 feet above the ground. Trees on slopes are measured from the ground level on the lower side of the tree. If a tree splits into multiple trunks below 4.5 feet, the trunk's diameter is measured at its most narrow point below the split.
B. 
New Trees. New trees are measured in caliper inches, which is the diameter of the trunk 6 inches above the ground.
(Ord. 1598)

11.1.15.040 Determining Average Front Setback-RHD-20 District.

A. 
Average Front Setback Determination. Average front setback is determined by the following calculations.
1. 
Determine Required Setback Area. The required average front setback is determined by multiplying the required minimum setback depth, 12 feet, by the frontage of the lot, minus the width of the required minimum side yard setbacks.
Sample calculations are provided below.
a. 
For a 25-foot wide lot: 12 x (25-6) = 228 sq. ft.
(Side yard setback 10% of the lot width and is a minimum of 3 feet)
b. 
For a 50-foot wide lot: 12 x (50-10) = 480 sq. ft.
(Side yard setback 10% of the lot width)
2. 
Determine Ground Level Setback Area. The ground level setback area is calculated by summing the areas of each area of change of building articulation between the required side yard setback lines. Refer to Figure 11.1.15.040.A: Determination of Average Front Setback Area.
3. 
Determine Second Level Setback Area. The second level setback area is calculated by summing the areas of each area of change of building articulation between the required side yard setback lines.
4. 
Confirm Required Setback Area. The required setback area is confirmed if the sum of the ground level and second level setback areas equal or exceed the required setback area.
B. 
Exclusions for Measurements. Unenclosed porches, balconies and decks are not part of the habitable area of the residence and are included as allowable setback area.
C. 
Maximum Depth to Wall Face. Any portion of a residence setback more than 20 feet shall be considered to be set back 20 feet for the purpose of calculating the average front setback.
Figure 11.1.15.040.A Determination of Average Front Setback Area
(Ord. 1598)

11.1.15.045 Determining Floor Area.

Floor area is the horizontal area (expressed in square feet) of all floors included within a building or buildings, according to the following rules:
A. 
Included in Floor Area. Floor area includes:
1. 
The floor of atrium and lobby areas;
2. 
Enclosed and roofed storage and equipment spaces;
3. 
Enclosed and roofed halls, stairways, and elevator shafts;
4. 
Enclosed and roofed porches and balconies;
5. 
Portions of basements and attics that meet California Building Code (per Title 9, Chapter 9.60: Building Code of the Seal Beach Municipal Code) height requirements for living space (any area where the wall height is 5 feet or greater is counted as floor area). See Figure 11.1.15.045.A: Floor Area Under Sloping Roof;
6. 
The actual floor space of mezzanines, interior balconies, and lofts.
B. 
Excluded from Floor Area. Floor area does not include:
1. 
Garages, carports, or other areas used for parking and loading, or vehicular access to parking and loading spaces;
2. 
Unenclosed balconies, decks, porches, and stairs;
3. 
Substandard height portions of attics and basements (per Title 9, Chapter 9.60: Building Code of the Seal Beach Municipal Code);
4. 
The area within a building adjacent to, and in an imaginary horizontal plane with, interior balconies, mezzanines, or lofts.
Figure 11.1.15.045.A Floor Area Under Sloping Roof
(Ord. 1598)

11.1.15.050 Determining Floor Area Ratio.

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.
(Ord. 1598)

11.1.15.055 Determining Lot Coverage.

Lot coverage is the ratio of the footprint of all structures on a lot to the lot area, typically expressed as a percentage. The footprints of all principal and accessory structures, including garages, carports, and roofed porches, shall be summed in order to calculate lot coverage. See also Section 11.4.05.100: Residential Accessory Uses and Structures. The following structures shall be excluded from the calculation:
