John Conley, City Manager Agenda Location: Public Hearing SUBJECT: ADOPTION OF 2025 CALIFORNIA FIRE CODE AND 2025 CALIFORNIA WILDLAND-

URBAN INTERFACE CODE WITH AMENDMENTS
RECOMMENDATION:

1.Open, conduct, and close public hearing to receive testimony regarding amending Chapter 16 of the Vista Municipal Code related to the Fire Code and the Wildland-Urban Interface Code.

2.Introduce and adopt City Council Ordinance No. 2025- , amending chapter 16.40 of the Vista Municipal Code related to the Fire Code and adding chapter 16.42 of the Vista Municipal Code related to the Wildland-Urban Interface Code.

CORRELATION TO CITY COUNCIL GOALS: Public Safety
PRIOR ACTION: On November 15, 2022, introduced and adopted City Council Ordinance No. 2022-20, adopting the 2023 California Fire Code and the 2022 International Fire Code with certain amendments, additions, and deletions (Vote: 5-0).

STATEMENT ON THE SUBJECT: The California Fire Code and the Wildland-Urban Interface Code establish minimum fire-safety standards for new construction, existing buildings, properties, and operations within the City. Authority for local adoption and amendment of these codes is provided under California Health and Safety Code Section 17958 and Government Code Sections 50022.1–50022.8.

The adoption cycle occurs every three years, consistent with revisions to the International Fire Code. If the City does not adopt the updated codes with local amendments, the State-adopted codes would automatically apply.

The proposed amendments are primarily technical, including updates related to battery energy storage systems, fire sprinkler requirements, and ground-mounted solar arrays. Adoption of the 2025 Wildland-Urban Interface Code introduces new home hardening and defensible space requirements that enhance wildfire resilience. These updates ensure consistency with the current building, electrical, and plumbing codes.

Assembly Bill 130 (effective January 1, 2024) requires that any local amendments more restrictive than the State code be supported by findings based on local climatic, geological, or topographical conditions and be submitted to the State prior to October 1, 2025. Adoption of the proposed ordinances satisfies these requirements and allows the City to carry forward existing standards while incorporating necessary local changes to safeguard public health, safety, and general welfare.

2. Code Amendment.

A. Chapter 16.40, Fire Code, of the Vista Municipal Code is amended to read as follows:

“Chapter 16.40

Fire Code

Sections:

16.40.010 Adoption of Fire Code

16.40.020 Amendments

SECTION 1. FINDINGS FOR THE FIRE CODE

Finding 1

The City of Vista herewith make findings that flood conditions carry the potential for overcoming the ability of the fire department to aid or assist in fire control, evacuations, rescues and the emergency task demands inherent in such situations. The potential for flooding conditions results in limiting fire department emergency vehicular traffic, with resulting overtaxing fire department personnel, may further cause a substantial or total lack of protection against fire for the buildings and structures located within the jurisdiction.

Finding 2

The City of Vista is situated near three major faults, each capable of generating earthquakes of significant magnitude. These are the Rose Canyon Fault, the Elsinore Fault, and the Agua Caliente Fault. These faults are subject to becoming active at any time; the City of Vista is particularly vulnerable to devastation should such an earthquake occur.

The potential effects of earthquake activity include isolating certain areas of City of Vista from the surrounding area and restricting or eliminating internal circulation due to the potential for collapsing of highway overpasses and underpasses, along with other bridges in the area, or an earth slide, and the potential for vertical movement rendering surface travel unduly burdensome or impossible.

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA

Finding 3

The City of Vista is bisected by San Diego County of San Diego ROADWAY SYSTEM . This highway is heavily traveled by transportation vehicles carrying known toxic, flammable, explosive and hazardous materials. The potential for release or threatened release of a hazardous material along this route and others within the district is likely given the volume transported daily. Incidents of this nature will normally require all available emergency response personnel to prevent injury and loss of life and to prevent, as far as practicable, property loss.

Emergency personnel responding to such aforementioned incidents may be unduly impeded and delayed in accomplishing an emergency response as a result of this situation. With the potential result of undue and unnecessary risk to the protection of life and public safety and, in particular, endangering residents and occupants in buildings or structures without the protection of automatic fire sprinklers.

Finding 4

Much of the rural area of the City of Vista is a mountainous topography and lacks the infrastructure needed for water supply (fire flow) and experiences water shortages from time to time. Those conditions have severely adverse effect on water availability for firefighting. Fires starting in sprinklered buildings are typically controlled by one or two sprinkler heads, flowing as little as 13 gallons per minute.

Hose streams used by engine companies on well- established structure fires operate at about 250 gallons per minute each, and the estimated water need for a typical residential fire is 1,250 to 1,500 gallons per minute, according to the Insurance Service Office and the 2025 California Fire Code.

Under circumstances such as, lack of water infrastructure, earthquakes, multiple fires and wildland fires within a community, the limited water demands needs of residential fire sprinklers would control and extinguish many fires before they spread from building to wildland. In such a disaster, water demands needed for conflagration firefighting probably would not be available.

Finding 5

The topography of the City of Vista presents problems in delivery of emergency services, including fire protection. Hilly terrain has narrow, winding roads with very little circulation, preventing rapid access and orderly evacuation. Much of these hills are covered with highly combustible natural vegetation. In addition to access and evacuation problems, the terrain makes delivery of water extremely difficult. Some hill areas are served by water pump systems subject to failure in fire, high winds, earthquake and other power failure situations. This would only allow domestic gravity feed water from tanks and not enough water for fire fighting.

Finding 6

Due to the mountainous topography in much of the rural area of the City of Vista , roadway condition, gates, angle of approach or departure, steeply sloping roadways and grades are common. it is very important that roadways be named and identified in order to facilitate emergency response.

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA

Finding 7

Due to the mountainous topography in much of the rural area of the City of Vista , steep, narrow and winding roads and areas of heavy brush are common. These features make it difficult for emergency response personnel to easily and quickly find the location of the site that requires assistance. It is therefore essential that street numbers and signs be easily readable to ensure the quickest response times for a given location.

Finding 8

Due to access and mountainous topography in much of the City of Vista , difficult roadway conditions, gates, angle of approach or departure, steeply sloping roadways and grades are common. In addition, combining potentially severe rainstorms and ground water retention of many areas of the District where there is expansive soil. This produces a condition wherein the moisture content of the soil is sufficient that roadways become damaged due to soil expansion and shrinkage. All weather, paved surfaces capable of supporting the imposed loads of fire apparatus are necessary to ensure access of emergency response personnel. These roadways, gates, approach angles, steep slopes and grades can also make it difficult for fire apparatus and other emergency vehicles to access a site. It is therefore essential that these roadway accesses be provided with proper all weather, paved surfaces, angle of approach, grades and gate access.

Finding 9

Due to the mountainous topography served by most of the City of Vista, conditions exist such as poor water supply, poor access roads, steep grades and steep canyon slopes. In addition, the distances emergency response personnel must travel can be very large and the response times can be long. Numerous studies of the growth of a fire in relation to time have proven that at ten minutes the fire is expected to have burned beyond control and any occupants remaining in the burning building would not be expected to survive. A ten-minute response time more realistically represents the time beyond which serious injury or death is expected to occur. It is therefore found that the City of Vista response time at which mitigation would be required, is 10 minutes. Such mitigation would be in the form of fire sprinklers or increased fire flow. In addition, with fire sprinklers and smoke detectors together have reduced the number of fatalities in homes by 59%.

Finding 10

Areas in the City of Vista can have special fire prevention needs not fully covered by the provisions of the Fire Code itself. This is due to the unique topographic features demographics, infrastructure, and local economics of the City of Vista.

Finding 11

The topography of the City of Vista presents problems in delivery of emergency services, including fire protection. Hilly terrain has narrow, winding roads with little circulation, preventing rapid access and orderly evacuation. Much of these hills are covered with highly non-fire resistive natural vegetation. In addition to access and evacuation problems, the terrain makes delivery of water extremely difficult. Some hill areas are served by water tank and pump systems are subject to failure in fire, high winds, earthquake and other power failure situations. 09/23/2025 PH3 6 of 176

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA

The aforementioned problems are set forth in the 2025 California Building Code and amendments.

Finding 12

The seasonal climatic conditions during the late summer and fall create numerous serious difficulties regarding the control of and protection against fires in the City of Vista. The hot, dry weather typical of this area in summer and fall, coupled with Santa Ana winds and low humidity frequently results in wildfires that threaten or could threaten the City of Vista.

Although some code requirements, such as fire-resistive roof classification, have a direct bearing on building survival in a wildland fire situation, others, such as residential fire sprinklers, may also have a positive effect. In dry climate on low humidity days, many materials are much more easily ignited. More fires are likely to occur and any fire, once started, can expand extremely rapidly. Residential fire sprinklers can arrest a fire starting within a structure before the fire is able to spread to adjacent brush and structures.

A seasonal wind also have the potential for interfering with emergency vehicle access, delaying or making impossible fire responses, because of toppling of extensive plantings of dense chaparral, eucalyptus and confers trees. The trees are subject to uprooting in strong winds due to relatively small root bases compared to the tree itself. The aforementioned problems support the imposition of fire-protection requirements greater than those set forth in the Building Code or Fire Code.

Finding 13

Every five years the State Fire Marshals Office is required to release fire hazard severity threat maps to each County. Local jurisdictions are required to adopt and amend, if necessary, the hazard classifications. The County of San Diego SRA maps have three identified areas.

Moderate, High and Very High Hazard Severity Zones. These zones are layers of data that reflect the potential for that area to be threatened with a wildfire over the next 25 years. With the passage of SB63 maps are now required on LRA Very High Fire Hazard Severity Zones.

Therefor due to the probability and potential for wildfires to occur in conjunction with the above findings the City of Vista hereby identifies the necessity to be more restrictive on home hardening and defensible space requirements located in our geographical areas.

In Southern California the area has been identified by nationally recognized RISK mapping software such as FEMA National Risk Index ( https://hazards.fema.gov/nri/map) and or Wildfirerisk.org ( https://wildfirerisk.org/explore/risk-to-homes/06/06073/) San Diego having 100% chance of wildfire risk over the next 25 years. Due to these catastrophic risks in conjunction with the above findings the City of Vista amends the model codes in local ordinances to be more restrictive in building construction and defensible space.

DEFINITIONS:

CLIMATE. The average course or condition of the weather at a particular place over a period of many years, as exhibited in absolute extremes, means and frequencies of given departures from these means (i.e., of temperature, wind velocity, precipitation and other weather elements).

CLIMATIC CONSIDERATIONS:

Climate conditions are classified into two categories: macro-climate and micro-climate. Macro- climate refers to the broad climatic conditions that affect an entire region, establishing the general environmental context for that area. Micro-climate refers to localized climatic variations within a region that result from specific topographical and geographical features. Micro-climatic conditions may vary significantly across relatively small areas and can create distinct environmental conditions for different neighborhoods or communities within the City of Vista, even when those areas are located within the same macro-climatic zone.

Climatic consideration should be given to the extremes, means, and anomalies of the following weather elements:

1. Temperatures.

2. Relative humidifies.

3. Precipitation and flooding conditions.

4. Wind speed and duration of periods of high velocity.

5. Wind direction.

6. Fog and other atmospheric conditions.

TOPOGRAPHY. The configuration of landmass surface, including its relief (elevation) and the position of its natural and man-made features that affect the ability to cross or transit a terrain.

TOPOGRAPHIC CONSIDERATIONS:

Topographic considerations should be given to the presence of the following topographical elements:

1. Elevation and ranges of elevation.

2. Location of ridges, drainages and escarpments.

3. Percent of grade (slope).

4. Location of roads, bridges and railroads.

5. Other topographical features, such as aspect exposure.

This information becomes an important part of creating an analysis of urban-wildland areas because topography and slope are key elements (along with fuel type) that create the need for specific ignition-resistance requirements in this code.

GEOGRAPHY. A science that deals with the earth and its life, especially the description of land, sea, air, and the distribution of plant and animal life including man and his industries with reference to the mutual relations of these diverse elements (Webster’s Third New California Dictionary).

09/23/2025 PH3 8 of 176

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA
PAGE 7

GEOGRAPHIC CONSIDERATIONS:

Geography should be evaluated to determine the relationship between man-made improvements (creating an exposure) and factors such as the following:

1. Fuel types, concentration in a mosaic and distribution of fuel types.

2. Earthquake fault zones.

3. Hazardous material routes.

4. Artificial boundaries created by jurisdictional boundaries.

5. Vulnerability of infrastructure to damage by climate and topographical concerns.

NOW THEREFORE, the City Council of the City of Vista does ordain as follows:

2. Code Amendment.

“SECTION 1. FINDINGS FOR WUI CODE

Finding 1 (FLOOD)
The City of Vista herewith makes findings that flood conditions carry the potential for overcoming the ability of the fire department to aid or assist in fire control, evacuations, rescues, and the emergency task demands inherent in such situations. The potential for flooding conditions results in limiting fire department emergency vehicular traffic, resulting in overtaxing fire department personnel, may further cause a substantial or total lack of protection against fire for the buildings and structures located within the jurisdiction.

Finding 2 (EARTHQUAKE)
The City of Vista is situated near three major faults, each capable of generating earthquakes of significant magnitude. These are the Rose Canyon Fault, the Elsinore Fault, and the Agua Caliente Fault. These faults are subject to becoming active at any time; the City of Vista is particularly vulnerable to devastation should such an earthquake occur.

The potential effects of earthquake activity include isolating certain areas of City of Vista from the surrounding area and restricting or eliminating internal circulation due to the potential for collapsing of highway overpasses and underpasses, along with other bridges in the area, or an earth slide, and the potential for vertical movement rendering surface travel unduly burdensome or impossible.

09/23/2025 PH3 43 of 176

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA
PAGE 42

Finding 3 (MOBILITY)
The City of Vista is bisected by San Diego County roadway system. This highway is heavily traveled by transportation vehicles carrying known toxic, flammable, explosive, and hazardous materials. The potential for release or threatened release of hazardous material along this route and others within the City is likely given the volume transported daily. Incidents of this nature will normally require all available emergency response personnel to prevent injury and loss of life and to prevent, as far as practicable, property loss. Emergency personnel responding to such aforementioned incidents may be unduly impeded and delayed in accomplishing an emergency response as a result of this situation. With the potential result of undue and unnecessary risk to the protection of life and public safety and, in particular, endangering residents and occupants in buildings or structures without the protection of automatic fire sprinklers.

Finding 4 (WATER SUPPLY)
Much of the rural area of the City of Vista is a mountainous topography and lacks the infrastructure needed for water supply (fire flow) and experiences water shortages from time to time. Those conditions have severely adverse effects on water availability for firefighting. Fires starting in sprinklered buildings are typically controlled by one or two sprinkler heads, flowing as little as 13 gallons per minute.

Hose streams used by engine companies on well-established structure fires operate at about 250 gallons per minute each, and the estimated water need for a typical residential fire is 1,250 to 1,500 gallons per minute, according to the Insurance Service Office and the 2025 California Fire Code (CFC).

Under circumstances such as lack of water infrastructure, earthquakes, multiple fires, and wildland fires within a community, the limited water demands of residential fire sprinklers would control and extinguish many fires before they spread from building to wildland. In such a disaster, water demands needed for conflagration firefighting probably would not be available.

Finding 5 (TOPOGRAPHY)
The topography of the City of Vista presents problems in delivery of emergency services, including fire protection. Hilly terrain has narrow, winding roads with very little circulation, preventing rapid access and orderly evacuation. Many of these hills are covered with highly combustible natural vegetation. In addition to access and evacuation problems, the terrain makes delivery of water extremely difficult. Some hill areas are served by water pump systems subject to failure in fire, high winds, earthquake, and other power failure situations. This would only allow domestic gravity to feed water from tanks and not enough water for firefighting.

Finding 6 (ACCESS)
Due to the mountainous topography in much of the rural area of the City of Vista, roadway condition, gates, angle of approach or departure, steeply sloping roadways, and grades are common. It is very important that roadways be named and identified in order to facilitate emergency response.

Finding 7 (ADDRESS MARKINGS)
Due to the mountainous topography in much of the rural area of the City of Vista, steep, narrow and winding roads, and areas of heavy brush are common. These features make it difficult for emergency response personnel to easily and quickly find the location of the site that requires assistance. It is therefore essential that street numbers and signs be easily readable to ensure the quickest response times for a given location.

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA
PAGE 43

Finding 8 (ALL WEATHER SURFACING) (ACCESS)
Due to access and mountainous topography in much of the City of Vista, difficult roadway conditions, gates, angle of approach or departure, steeply sloping roadways, and grades are common. In addition, there are many areas of the City where there is expansive soil combining potentially severe rainstorms and ground water retention. This produces a condition wherein the moisture content of the soil is sufficient that roadways become damaged due to soil expansion and shrinkage. All weather, paved surfaces capable of supporting the imposed loads of fire apparatus are necessary to ensure access of emergency response personnel. These roadways, gates, approach angles, steep slopes, and grades can also make it difficult for fire apparatuses and other emergency vehicles to access a site. It is therefore essential that these roadway accesses be provided with proper all weather, paved surfaces, angle of approach, grades, and gate access.

Finding 9 (TRAVEL TIME)
Due to the mountainous topography served by most of the City of Vista, conditions exist such as poor water supply, poor access roads, steep grades, and steep canyon slopes. In addition, the distances emergency response personnel must travel can be very large and the response times can be long. Numerous studies of the growth of a fire in relation to time have proven that at ten minutes the fire is expected to have burned beyond control and any occupants remaining in the burning building would not be expected to survive. A ten-minute response time more realistically represents the time beyond which serious injury or death is expected to occur. It is therefore found that the City of Vista response time at which mitigation would be required is 10 minutes.

Such mitigation would be in the form of fire sprinklers or increased fire flow. In addition, fire sprinklers and smoke detectors together have reduced the number of fatalities in homes by 59%.

Finding 10 (AREAS NOT COVERED)
Areas in the City of Vista can have special fire prevention needs not fully covered by the provisions of the Code itself. This is due to the unique topographic features, demographics, infrastructure, and local economics of the City of Vista.

Finding 11 (HOME HARDENING)
The topography of the City of Vista presents problems in delivery of emergency services, including fire protection. Hilly terrain has narrow, winding roads with little circulation, preventing rapid access and orderly evacuation. Much of these hills are covered with highly non-fire resistive natural vegetation. In addition to access and evacuation problems, the terrain makes delivery of water extremely difficult. Some hill areas are served by water tank and pump systems that are subject to failure in fire, high winds, earthquakes, and other power failure situations.

The aforementioned problems are set forth in the 2025 California Building Code and amendments.

Finding 12 (WEATHER)
The seasonal climatic conditions during the late summer and fall create numerous serious difficulties regarding the control of and protection against fires in the City of Vista. The hot, dry weather typical of this area in summer and fall, coupled with Santa Ana winds and low humidity frequently results in wildfires that threaten or could threaten the City of Vista. 09/23/2025 PH3 45 of 176

Although some code requirements, such as fire-resistive roof classification, have a direct bearing on building survival in a wildland fire situation, others, such as residential fire sprinklers, may also have a positive effect. In dry climate on low humidity days, many materials are much more easily ignited. More fires are likely to occur and any fire, once started, can expand extremely rapidly. Residential fire sprinklers can arrest a fire starting within a structure before the fire is able to spread to adjacent brush and structures.

Seasonal winds also have the potential for interfering with emergency vehicle access, delaying or making impossible fire responses, because of toppling of extensive plantings of dense chaparral, eucalyptus, and conifer trees. The trees are subject to uprooting in strong winds due to relatively small root bases compared to the tree itself. The aforementioned problems support the imposition of fire-protection requirements greater than those set forth in the Building Code or Fire Code.

Finding 13 (FIRE THREAT/FIRE RISK)
Every five years the State Fire Marshal's Office is required to release fire hazard severity threat maps to each County. Local jurisdictions are required to adopt and amend, if necessary, the hazard classifications. The County of San Diego State Responsibility Area (SRA) maps have three identified areas: Moderate, High, and Very High Fire Hazard Severity Zones. These zones are layers of data that reflect the potential for that area to be threatened with wildfire over the next 25 years. With the passage of SB63 maps are now required on Local Responsibility Area (LRA) Very High Fire Hazard Severity Zones. Therefore, due to the probability and potential for wildfires to occur in conjunction with the above findings, the City of Vista hereby identifies the necessity to be more restrictive on home hardening and defensible space requirements located in our geographical areas.

In Southern California, the area has been identified by nationally recognized RISK mapping software such as Federal Emergency Management Agency (FEMA) National Risk Index ( https://hazards.fema.gov/nri/map) and/or Wildfirerisk.org ( https://wildfirerisk.org/explore/risk-to- homes/06/06073/) San Diego having 100% chance of wildfire risk over the next 25 years. Due to these catastrophic risks in conjunction with the above findings, the City of Vista amends the model codes in local ordinances to be more restrictive in building construction and defensible space.

Additional Findings for Wildland Urban-Interface Fire Areas

REQUIREMENTS FOR WILDLAND-URBAN INTERFACE FIRE AREAS
As required by Health and Safety Code Section 17958, the Vista City Council hereby makes express findings that amendments to the California Building Standards Code are necessary for the protection of public health, safety, and welfare due to certain climatic, topographic, and geological features existing within the City of Vista. To comply with conditions outlined in AB130 citing Health & Safety Code Section 13869.7, the Vista City Council finds that due to the extreme conditions listed below, home hardening and defensible space measures are required to protect the public and therefore necessitate local amendments.

DEFINITIONS:

CLIMATE. The average course or condition of the weather at a particular place over a period of many years, as exhibited in absolute extremes, means, and frequencies of given departures 09/23/2025 PH3 46 of 176

ORDINANCE NO. 2025-

CITY COUNCIL OF THE CHARTERED CITY OF VISTA
PAGE 45

from these means (i.e., of temperature, wind velocity, precipitation, and other weather elements).

CLIMATIC CONSIDERATIONS:

Climate conditions are classified into two categories: macro-climate and micro-climate. Macro- climate refers to the broad climatic conditions that affect an entire region, establishing the general environmental context for that area. Micro-climate refers to localized climatic variations within a region that result from specific topographical and geographical features. Micro-climatic conditions may vary significantly across relatively small areas and can create distinct environmental conditions for different neighborhoods or communities within the City of Vista, even when those areas are located within the same macro-climatic zone.

Climatic consideration should be given to the extremes, means, and anomalies of the following weather elements:

1. Temperatures.

2. Relative humidities.

3. Precipitation and flooding conditions.

4. Wind speed and duration of periods of high velocity.

5. Wind direction.

6. Fog and other atmospheric conditions.

GEOGRAPHY. A science that deals with the earth and its life, especially the description of land, sea, air, and the distribution of plant and animal life including man and his industries with reference to the mutual relations of these diverse elements. Webster's Third New California Dictionary

GEOGRAPHIC CONSIDERATIONS:

Geography should be evaluated to determine the relationship between man-made improvements (creating an exposure) and factors such as the following:

1. Fuel types, concentration in a mosaic, and distribution of fuel types.

2. Earthquake fault zones.

3. Hazardous material routes.

4. Artificial boundaries created by jurisdictional boundaries.

5. Vulnerability of infrastructure to damage by climate and topographical concerns.

TOPOGRAPHY. The configuration of landmass surface, including its relief (elevation) and the position of its natural and man-made features that affect the ability to cross or transit a terrain.

TOPOGRAPHIC CONSIDERATIONS:

Topographic considerations should be given to the presence of the following topographical elements:

1. Elevation and ranges of elevation.

2. Location of ridges, drainages, and escarpments.

3. Percent of grade (slope).

4. Location of roads, bridges, and railroads.

5. Other topographical features, such as aspect exposure.

This information becomes an important part of creating an analysis of urban-wildland areas because topography and slope are key elements (along with fuel type) that create the need for specific ignition-resistance requirements in this code. 09/23/2025 PH3 47 of 176

Sec. 201.4 Terms not defined. Where terms are not defined through the methods authorized by this section, such terms shall have their ordinarily accepted meanings such as the context implies.

SEC. 202 DEFINITIONS

Section 202 of the California WUI Code is revised to add the following definitions:

CLIMATE. The average course or condition of the weather at a particular place over a period of many years, as exhibited in absolute extremes, means, and frequencies of given departures from these means (i.e., of temperature, wind velocity, precipitation, and other weather elements).

CLIMATIC CONSIDERATIONS:

Climate conditions are classified into two categories: macro-climate and micro-climate. Macro- climate refers to the broad climatic conditions that affect an entire region, establishing the general environmental context for that area. Micro-climate refers to localized climatic variations within a region that result from specific topographical and geographical features. Micro-climatic conditions may vary significantly across relatively small areas and can create distinct environmental conditions for different neighborhoods or communities within the City of Vista, even when those areas are located within the same macro-climatic zone.

Climatic consideration should be given to the extremes, means, and anomalies of the following weather elements:

1. Temperatures.

2. Relative humidities.

3. Precipitation and flooding conditions.

4. Wind speed and duration of periods of high velocity.

5. Wind direction.

6. Fog and other atmospheric conditions.

GEOGRAPHY. A science that deals with the earth and its life, especially the description of land, sea, air, and the distribution of plant and animal life including man and his industries with reference to the mutual relations of these diverse elements. Webster's Third New California Dictionary

GEOGRAPHIC CONSIDERATIONS:

Geography should be evaluated to determine the relationship between man-made improvements (creating an exposure) and factors such as the following:

1. Fuel types, concentration in a mosaic, and distribution of fuel types.

2. Earthquake fault zones.

3. Hazardous material routes.

4. Artificial boundaries created by jurisdictional boundaries.

5. Vulnerability of infrastructure to damage by climate and topographical concerns.

TOPOGRAPHY. The configuration of landmass surface, including its relief (elevation) and the position of its natural and man-made features that affect the ability to cross or transit a terrain.

09/23/2025 PH3 160 of 176

Vista Municipal Code

16.42 (6)

(Vista 09/23/25)
TOPOGRAPHIC CONSIDERATIONS:

Topographic considerations should be given to the presence of the following topographical elements:

1. Elevation and ranges of elevation.

2. Location of ridges, drainages, and escarpments.

3. Percent of grade (slope).

4. Location of roads, bridges, and railroads.

5. Other topographical features, such as aspect exposure.

This information becomes an important part of creating an analysis of urban-wildland areas because topography and slope are key elements (along with fuel type) that create the need for specific ignition-resistance requirements in this code.

SEC. 401.3.2 FIRE APPARATUS ACCESS MODIFICATIONS

Section 401.3.2 is added to the California WUI Code to read:

Sec. 401.3.2 Fire apparatus access modifications. Plans for the modification of fire apparatus access road shall be submitted to the fire code official for review and approval prior to construction or modification of any fire apparatus road.

Sec. 404.6 Fire flow. Fire flow requirements shall be based on Appendix B of the CFC or the standard published by the Insurance Services Office, "Guide for Determination of Required Fire Flow." Consideration should be given to increasing the gallons per minute to protect buildings and structures of extremely large square footage and for such reasons as: poor access roads, grade and canyon rims, hazardous brush, and response times greater than five minutes by a recognized fire department or fire suppression company. In hazardous fire areas the main capacity for new subdivisions shall not be less than 2,500 – 3,000 gallons per minute, unless otherwise approved by the fire code official. If fire flow increases are not feasible, the fire code official may require alternative design standards such as: alternative types of construction that provides a higher level of fire resistance, fuel break requirements, which may include required irrigation, modified access road requirements, specified setback distances for building sites addressing canyon rim developments and hazardous brush areas, and other requirements as authorized by this chapter and as required by the fire code official.
