X. SAFETY ELEMENT
X. SAFETY ELEMENT
Purpose
The purpose of the safety element is to reduce the potential risk of death, injuries, property
damage, and economic and social dislocation resulting from fires, floods, earthquakes and other
hazards. This element is required to include mapping of known seismic and other geologic
hazards and also to address other locally relevant safety issues such as:
• hazardous materials spills;
• hazardous and toxic materials storage and disposal;
• wildland and urban fires;
• emergency response capacity;
• flooding, storm drainage; and
• potable water quality.
A second purpose of this element is to guide land use planning and policy decisions in order to
achieve an acceptable level of public safety from known natural and man- made hazardous
events.
Geologic and Seismic Hazards
S
EISMIC HAZARDS
Earthquakes originate as movement or slippage occurring along an active fault. These
movements generate shock waves that result in ground shaking. Structures of all types, if not
designed or constructed to withstand ground shaking, may suffer severe damage or collapse.
Likewise, some slopes will collapse due to the soil or geological characteristics resulting in
hazard both in terms of collapse of structures located thereon, or collapse of structures within the
ath of resulting p land slides.
The severity of damage to buildings from earthquakes is related to the intensity of
groundshaking, soils and geologic characteristics, and the type of building construction used.
High risk areas in Lakeport do not have any critical facilities such as high- occupancy buildings,
hospitals, or schools. The land use pattern that has evolved in Lakeport has, in general, avoided
high- risk areas.
Lakeport is located in a highly active earthquake area and the potential exists for a significant
seismic event in the future. Immediately east of the city, between the city limits and Clear Lake,
there is a potentially active rupture zone. Potentially active rupture zones are faults which have
been active in the past 2,000 years. Little is known about this shoreline fault rupture zone,
however, it represents a potentially significant hazard and must be taken into consideration when
development occurs in the vicinity. Within the past 200 years, no major earthquakes have
occurred along faults in Lake County.

To the west of the city lie the San Andreas fault and the Healdsburg fault, 30 and 15 miles away,
respectively. Both of these faults have been responsible for moderate to major seismic events in
the past. The maximum earthquake magnitudes observed to date are 8.5 for the San Andreas
fault and 6.75 ( Richter Scale1) for the Healdsburg fault.
Figure 16 shows the 2001 Fault- Rupture Hazard Zones maps prepared by the California
Geological Survey. Most of the ground shaking which has occurred in past years in the Lakeport
area has come from faults in the Mayacamas and Mt. Konocti area. Additionally, fault zones run
diagonally in a southeast to northwest direction through the Potato Hill, Lake Pillsbury and
Sanhedrin areas. In the far southeastern corner of the County there is a fault zone in the Jericho
Valley, an area that runs along the Lake/ Napa County line.
Communities containing structures built with unreinforced masonry walls are particularly
susceptible to damage from earthquakes. The Unreinforced Masonry Law passed by the State
Legislature in 1986 [ SB 547], requires all cities and counties in Seismic Zone 4 to identify
potentially hazardous unreinforced masonry buildings. The City has complied with this
legislation and identified several unreinforced masonry buildings. Implementation of an
inspection and reinforcement program was carried out to help mitigate hazards associated with
seismic effects on structures. A comprehensive structural rehabilitation program was not carried
out city- wide.
In addition to unreinforced masonry buildings, other key community structures are also
considered at- risk in the occurrence of a seismic event.
• All critical emergency buildings ( city hall, police and fire stations);
• High priority buildings ( theaters, schools, limited care facilities)
• The majority of high- use buildings ( commercial and office buildings, large apartment
buildings, and churches);
A major earthquake would be expected to cause considerable damage to transportation systems.
Roads, bridges and highway overpasses all cross various earthquake faults as well as areas
susceptible to ground failure.
LIQUEFACTION
Liquefaction is a phenomenon in which the strength and stiffness of the soil is reduced by
earthquake shaking or other rapid loading. Liquefaction and related phenomena have been
responsible for tremendous amounts of damage in earthquakes around the world.
1 Seismic waves are the vibrations from earthquakes that travel through the Earth; they are recorded on instruments called seismographs.
Seismographs record a zigzag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs,
which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. The time, locations, and
magnitude of an earthquake can be determined from the data recorded by seismograph stations. The Richter magnitude scale was developed in
1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
Public Review Draft - Safety Element January, 2006
City of Lakeport General Plan Update Page X- 2
Liquefaction occurs in saturated soils, that is, soils in which the space between individual
particles is completely filled with water. This water exerts a pressure on the soil particles that
influences how tightly the particles themselves are pressed together. Prior to an earthquake, the
water pressure is relatively low. However, earthquake shaking can cause the water pressure to
increase to the point where the soil particles can readily move with respect to each other. When
liquefaction occurs, the strength of the soil decreases and, the ability of a soil deposit to support
foundations for buildings and bridges is reduced. Liquefied soil also exerts higher pressure on
retaining walls, which can cause them to tilt or slide. This movement can cause settlement of the
retained soil and destruction of structures on the ground surface. Increased water pressure can
also trigger landslides and cause the collapse of dams. Because liquefaction only occurs in
saturated soil, its effects are most commonly observed in low- lying areas near bodies of water
such as rivers, lakes, bays, and oceans. Soils in and around Lakeport, especially near the lake
shore, are susceptible to liquefaction during a seismic event.
SEICHES OR DAM FAILURES
A significant seismic event near Lakeport could potentially cause large waves to form on Clear
Lake called a seiche. Seiching is the formation of standing waves in a water body due to wave
formation and subsequent reflections from the ends. These waves may be incited by earthquake
motions ( similar to the motions caused by shaking a glass of water), impulsive winds over the
surface, or due to wave motions entering the basin. The various modes of seiching correspond to
the natural frequency response of the water body.
A seiche inundation zone has been identified, which is an area between the normal shoreline of
Clear Lake and ten feet above flood stage, which is approximately at the 1,431 ft. contour
elevation ( see Figure 17). The risks associated with seiche are considered to be relatively low
compared to the risks from earthquake and liquefaction with the Lakeport area.
The City of Lakeport Municipal Sewer District ( CLMSD) maintains an earthen dam in the south
west part of the Planning Area, near the intersection of Highways 29 and 175, for the retention of
treated wastewater. The dam will store a total of 660 acre feet of water and has been approved
by the State. The possibility of catastrophic collapse of this dam is remote. Should this occur,
however, the spill- out would result in a relatively minor inundation that would probably be
contained by existing drainage courses, with a low probability of loss of life or property damage.
Nonetheless, the City should require the CLMSD to prepare inundation maps, a warning system
and drainage plans in case of a seismic event when new construction or expansion to this facility
occurs.
LANDSLIDES
Landslides are a significant geologic constraint to development in the Lakeport Planning Area.
The landslide potential of an area is a function of the area’s hydrology, geology, and seismic
characteristics. Clay soils, which underlie many hillsides in Lakeport are particularly susceptible
to sliding. Although landslides generally occur in areas with steep slopes, they may occur on
slopes with a grade of 20% or less in geologically unstable areas. Since zones of moderate to
high landslide potential exist in Lakeport, soils tests carried out by a registered soils engineer or
geologist are essential wherever landslide potential is indicated or suspected. Foundations for
Public Review Draft - Safety Element January, 2006
City of Lakeport General Plan Update Page X- 3
structures built in areas with steep slopes in excess of 20% must be carefully engineered to avoid
increasing landslide risk.
Flooding
Flooding has historically been one of Lakeport’s major safety concerns. Clear Lake and its
tributary drainages have a long history of flooding. In the past twenty years, federal disasters
due to flooding were declared six times in the City of Lakeport during 1983, 1986, 1995 ( twice),
1997, and 1998. Flooding in Lakeport historically results from two distinct types of events:
shoreline flooding due to high lake levels and wind velocity, and stream bank flooding caused by
high intensity cloudburst storms over one or more of the drainage areas. Conditions in the winter
tend to be conducive to both types of flood conditions at the same time.
Stream bank flooding affects most drainage within the city. Cloudburst storms lasting as long as
three hours can occur in the watersheds of Lakeport practically anytime during the fall, winter,
and spring and may occur as an extremely severe sequence in a general rainstorm. Cloudbursts
are high- intensity storms that can produce floods characterized by high peak flows, short
duration, and relatively small volume of runoff. In small drainage basins, such as those existing
in the Planning Area, cloudbursts can produce peak flows substantially larger than those of
general rainstorm runoff.
Lakeport is traversed by several streams and drainage areas which flow into Clear Lake. The
development that has occurred during the past twenty years has accentuated existing drainage
problems and has increased the potential for flooding. Continued construction of new buildings
increases the area of impermeable surface and thus the amount of storm water that flows through
the city’s storm drain system.
Water Supply Quality
The health of the entire community is dependent on a supply of potable water that is consistently
free from organic wastes, chemical contamination and other impurities. Lakeport obtains its
potable water from Clear Lake and from four wells located in the Planning Area. Potential
sources of contamination of the City's drinking water from agricultural runoff, chemical spills, and
groundwater contamination must be prevented. Ongoing monitoring of the quality of potable
water supplies for both coliform as well as trace quantities of chemical pollutants must be carried
out on a regular basis. The policies and implementation programs in this element focus on both
prevention of potable water contamination and water quality monitoring.
Asbestos Risk
The primary risk of exposure to asbestos in Lakeport comes from the disruption of naturally
occurring serpentine soil throughout the area. The word asbestos refers to several types of
fibrous minerals. In its natural state, asbestos occurs throughout much of the world, and is found
in two- thirds of the rocks in the earth's crust. Asbestos fibers are released into the air by
construction and farming activities which agitate the soil, and are also released naturally by
erosion.
Public Review Draft - Safety Element January, 2006
City of Lakeport General Plan Update Page X- 4
Asbestos is also used as an insulating material in public buildings and can pose a potential
health hazard. The Lakeport Unified School District has determined that public schools within
the City's Planning Area are in compliance with the 1986 Federal and State Building Codes for
asbestos insulation.
Emergency Preparedness
The City has an adopted Emergency Operations Plan. The purpose of this plan is to ensure that
the City will be prepared and respond effectively in the event of emergencies to save lives and
restore and protect property; repair and restore essential public services; provide for the
protection and distribution of medical, food, water and other vital supplies; and coordinate
operations with Civil Defense emergency organizations and other jurisdictions to maintain
continuity of government.
The County of Lake has prepared a comprehensive countywide emergency plan which will
provide the basis for an integrated and multi- jurisdictional response to large scale emergency
situations associated with natural and man- made disasters and Civil Defense operations.
Wildland and Urban Fire Hazards
The combination of vegetation, topography, climate and population density create a significant
potential for hazards from wildfires within the Lakeport Planning Area. There are many vacant
and undeveloped areas within the City and its Sphere of Influence, particularly on the west side
of Highway 29 and the northern portions of the City, including mobile home parks. Rugged
topography and highly flammable vegetation make residential development potentially unsafe
unless adequate fire safety measures are taken.
Urban fire hazards occur principally in older structures with common walls and attics and where
rear access is not possible. There are a number of older buildings in the Downtown District
which have a high fire potential for these reasons.
The area within the City is served by the Lakeport Fire Department, while the Sphere of
Influence is served by the Lakeport Fire Protection District. Any location within City limits can
be reached within three to five minutes. Locations within the Sphere of Influence can be reached
in five to seven minutes. This rapid response time can be attributed to the combination of full-time
staff and emergency personnel in the Lakeport Fire Department and a large number of
volunteers in the Lakeport Fire Protection District.
Police Protection
The Police Department continues to maintain adequate staffing levels and equipment to provide
protection of persons and property in Lakeport. This is accomplished through annual reviews of
the police budget, which takes into account increases in demand for services resulting from
additional mandates and a changing service area. Traffic- related activity, however, has increased
substantially in recent years relative to other police activities. The volume of traffic which
passes through Lakeport is increasing, irrespective of locally- generated land use and traffic
Public Review Draft - Safety Element January, 2006
City of Lakeport General Plan Update Page X- 5
changes occurring within the City's Planning Area. Traffic enforcement requires an increasing
police presence on city streets. Similarly, as unincorporated areas develop, and/ or become
annexed to the City, increasing demands will be placed on available personnel and equipment.
Transportation and Storage of Hazardous Materials
There exist potential public safety hazards in the Lakeport Planning Area associated with
hazardous materials transported by truck, the storage of hazardous materials, asbestos insulation
in public buildings and potential contamination of drinking water by hazardous materials.
The transportation and storage of hazardous materials is clearly a regional problem. A large
quantity of hazardous products are transported on highways where the potential for release of this
material into the environment represents a potentially significant public health risk. The policies
and programs dealing with hazardous materials in this element incorporate and build on other
relevant portions of the Safety Element of the Lake County General Plan.
Radioactive materials are distinguished from other hazardous materials and specific federal and
state regulations have been developed for these substances. The use and storage of radioactive
materials in Lakeport is limited to medical facilities, since no other primary users of radioactive
materials, such as research laboratories, nuclear power plants or military facilities, are located
within the Planning Area. The principal potential danger to Lakeport residents from these
materials is related to the possibility of a truck accident whereby containers holding radioactive
materials would rupture.
Aviation Hazards
Lampson Field Airport potentially affects land uses in Lakeport in the form of noise and safety
impacts, although it is located outside of the Planning Area. The County owns and operates this
general aviation airport and has prepared a Master Plan that reflects anticipated growth in general
aviation activity for the next 20 years. The Master Plan attempts to prohibit and/ or reduce
obstacles to air navigation, exposure of persons on the ground to accident and crash hazards, and
noise impacts through building height restrictions, land use limitations and building standards to
reduce interior noise.
The County's Airport Land Use Commission ( ALUC) regulates land use in an area surrounding
Lampson Field which includes a portion of Lakeport's Planning Area. The City must submit
projects within the County's ALUC referral area for their review and determination of
consistency with the policies of the Airport Master Plan. In addition, the City's General Plan
must be consistent with the policies established by the Airport Master Plan for the referral area.
