7.5.1. Goals, Objectives, Policies, and Implementation Programs.

This chapter outlines the City of Malibu's plan to encourage the provision of adequate housing to meet the needs of residents from all economic segments throughout the 2013-2021 planning period. The overriding housing goal of the City is:

GOAL: Adequate Housing for the Existing and Projected Needs of All Economic Segments of the Community

The City's policies and implementation programs designed to support this goal are organized into four general areas as described below.

  1. Preserve and Improve the Existing Housing Stock
Policy 1.1 Ensure compliance with existing codes to protect health, safety and community sustainability
Policy 1.2 Assist property owners in repairing or rebuilding damaged or deteriorated housing units, especially affordable housing
Policy 1.3 Preserve existing mobile home parks as an important source of affordable housing
Policy 1.4 Conserve affordable housing in the Coastal Zone

Program 1.1 - Code Enforcement

Ensure compliance with the City's codes and regulations. Particularly in the case of code violations in units that are occupied by lower-income persons or persons with special needs, direct property owners and renters to programs that are available to provide assistance. Offer amnesty and legalization for existing housing units where:

  1. The unit is "livable" and meets basic health and safety requirements;

  2. The unit existed at the time of the City's incorporation; and

  3. The unit is restricted for owner-occupancy or rental by low-or moderate-income persons at an affordable rate.

Responsible department: Planning Department
Funding source: General Fund; permit fees
Time frame: Throughout the planning period
Objective: Reduce code violations and health & safety issues in existing housing

Program 1.2 - Rebuilding Assistance

Expedite permit processing and provide special assistance to homeowners seeking to repair or rebuild homes that have been lost or damaged in a fire, flood or other disaster, especially units that accommodate low- and moderate-income households, elderly, disabled, large families, single heads of households, farm workers, individuals in need of emergency shelter, and other individuals or household types with special needs, unless those units are located in areas that are physically unsuitable for development.

Responsible department: Planning Department; Building & Safety Division
Funding source: General Fund; Federal Emergency Management Agency (FEMA); Office of Emergency Services (OES)
Time frame: Throughout the planning period
Objective: Facilitate rebuilding of lost or damaged homes

Program 1.3 - Housing Rehabilitation Assistance

Provide incentives to rehabilitate existing housing units, such as permit fee waivers for units that are deed-restricted for low- and moderate-income families.

Responsible department: Planning Department
Funding source: Affordable Housing Trust Fund
Time frame: Throughout the planning period
Objective: 4 units

Program 1.4 - Preserve Existing Mobile Home Parks

Maintain the Mobile Home Park Rent Control Regulations Ordinance that regulates maximum allowable rents and limits rent increases. Pursuant to the provisions of Government Code § 65863.7, require the submittal of a report detailing the impacts of any proposed mobile home park conversion to a nonresidential use concurrent with the filing of any discretionary permit on such property and impose reasonable mitigation measures upon the park owners.

Responsible department: City Manager's Department; State of California
Funding source: General Fund; registration fees
Time frame: Throughout the planning period
Objective: No net loss of mobile home units

Program 1.5 - Conserve Affordable Housing in the Coastal Zone

In accordance with Government Code § 65590, continue to require the replacement of low-or moderate-income units that have been removed from the coastal zone (either by demolition or conversion), whenever feasible.

Responsible department: Planning Department
Funding source: General Fund
Time frame: Throughout the planning period
Objective: LCP and M.M.C. amendment
  1. New Housing Development
Policy 2.1 Support a regional fair-share approach to meeting housing needs
Policy 2.2 Support a range of new housing development commensurate with the City's needs and consistent with environmental and public service limitations through all appropriate regulatory and administrative mechanisms

Program 2.1 - Regional Housing Needs Identification

Work with the Southern California Association of Governments (SCAG) and the Las Virgenes-Malibu Subregional Council of Governments (COG) to encourage an appropriate fair share allocation of future regional housing needs based on population need, existing supply/demand, ability to accommodate growth given the physical/environmental constraints and the jobs-to-housing ratio.

Responsible Department: City Manager; City Council liaison to COG; Planning Department
Funding source: General Fund
Time frame: Throughout the planning period
Objective: Encourage fair and realistic RHNA allocations

Program 2.2 - Ensure Adequate Capacity to Accommodate Regional Housing Needs

The City's residential land inventory provides adequate capacity to accommodate the City's housing needs as identified in the 2014-2021 RHNA (see Appendix B). The City will pursue a two-part strategy to provide sites for lower-income housing: 1) Opportunities and incentives for second units; and 2) Zoning regulations to facilitate affordable multi-family or mixed-use development in suitable locations.

A. Expand the Supply of Second Units

Second units represent an important source of affordable housing in Malibu (see Appendix B for further discussion of second unit production). Due to extraordinarily high land cost and environmental constraints, development of new affordable housing is very difficult. Since second units can be accommodated on developed sites at no additional land cost, they represent an excellent option for addressing the needs of seniors, university students, household employees, local service workers, and extended family members. In order to maximize the availability of additional second units, the City will implement the following actions:

  1. Promote the Development of Second Units - Develop a brochure to provide information on the City's second unit standards and incentives to promote their development. The brochure will be distributed at City Hall, posted on the website, and provided to all applicants for new residential development.

  2. Amnesty Program for Second Units - Continue to implement the Second Unit Amnesty Program for legalized second units that meet all health and safety requirements. The amnesty program may include the waiver of City fees and penalties and will allow the legal registration of both second units and converted guest houses.

  3. Financial Assistance for Second Units - Contact local service providers, including the Water District and School District, to pursue reduced development impact fees on second units dedicated for occupancy by lower-income households. Evaluate mechanisms to subsidize impact fees using local, state, and nonprofit sources, including the City's Affordable Housing Trust Fund.

  4. Pre-Approved Second Unit Prototypes - Make available pre-approved second unit proto-type plans to assist applicants and streamline the approval process.

Responsible department: Planning Department
Funding sources: General Fund; Affordable Housing Trust Fund; other governmental agencies; grant funds
Time frame: Throughout the planning period
Objective: 21 second units during 2014-2021

B. Facilitate New Affordable Housing Development

In order to accommodate lower-income housing, the M.M.C. and LCP regulations were amended in the previous planning period to establish an Affordable Housing Overlay allowing multi-family or mixed-use development by-right at a density of 20 units/acre for projects that include affordable housing. In order to qualify for the increased density incentive, all "bonus" units (i.e., additional units allowed above the base density of 6 units per acre) must be deed-restricted for low-and moderate-income households for a minimum of 30 years at a ratio of 50% low-and 50% moderate-income. As an alternative, very-low-income units may offset the requirement for moderate-income units on a one-for-one basis.[1] Any developer utilizing these incentives shall be required to screen tenants or buyers for compliance with income limits and establish a monitoring system to ensure the unit's continued affordability. This program creates a strong incentive for affordable housing development because of the additional units allowed at 20 units per acre compared to the base density of 6 units per acre. The allowable density of 20 units per acre does not include the state-mandated density bonus, and it is anticipated that all projects utilizing this option will also qualify for a density bonus of up to 35%.

This program does not represent an "inclusionary" requirement because property owners who do not wish to take advantage of the density incentive would be allowed to develop market-rate housing at the allowable base density of 6 units/acre.

Incentives and concessions for ELI units will include a variety of housing types such as SROs and supportive housing. Incentives may include priority processing, density bonus, modified development standards, administrative support with funding applications, and/or fee waivers or deferrals.

In order to facilitate development of affordable housing, including housing for persons with developmental disabilities and other special needs, the City will contact non-profit developers annually to implement a strategy for developing housing, including site identification, priority processing, density bonus and modified development standards, administrative support with funding applications, and fee waivers or deferrals if feasible. The City has already had conversations with nonprofit developers regarding affordable housing opportunities on the La Paz site.

Responsible department: Planning Department
Funding source: Affordable Housing Trust; General Fund
Time frame: Throughout the planning period
Objective: Provide suitable sites with appropriate zoning that could accommodate lower-income housing

[1]

For example, a 20-unit qualifying project may provide 7 low-income units, 7 moderate-income units and 6 market-rate units; or as an alternative, 7 very-low-income units and 13 market-rate units.

Program 2.3 - Streamline Development Review and Assist Affordable Housing Developments

Streamline the development review and permit process for all residential development by providing a series of informational handouts describing how to apply for housing development and summarizing the basic development criteria for different zones. When developers propose to include affordable units in a project, provide assistance through expedited processing, density bonus and other modified development standards, and administrative assistance with grant applications.

Responsible department: Planning Department
Funding source: General Fund; permit fees
Time frame: Throughout the planning period
Objective: Minimize residential permit processing time and assist affordable housing developments
  1. Fair Housing and Assistance to Lower-Income Households and Persons with Special Needs
Policy 3.1 Facilitate the provision of fair housing services.
Policy 3.2 Remove regulatory barriers to housing for all residents, including those with special needs.
Policy 3.3 Provide financial support, where feasible, and referral information to persons in need of housing assistance.

Program 3.1 - Fair Housing

Support fair housing efforts by contracting with the Los Angeles County Housing Authority, Westside Fair Housing Council, or other appropriate organization, to create a program that provides fair housing services, including investigation of discrimination complaints, research on housing discrimination-related issues, public information about the rights and responsibilities of landowners and tenants, and landlord/tenant dispute resolution. Promote the program each year through the use of pamphlets, public bulletin boards on community television; educational flyers distributed to property owners, apartment managers and tenants; public service announcements on local radio stations and in local print media; and presentations at community groups.

Responsible department: Planning Department
Funding source: General Fund; CDBG
Time frame: Annual appropriation and semi-annual publications and announcements
Objective: Provide and publicize fair housing services through contracting with a public or non-profit service provider

Program 3.2 - Provide Financial Support and Referral Information to Persons in Need of Assistance

Malibu is a small jurisdiction without a redevelopment agency or housing department, and is not an entitlement jurisdiction for federal grants, such as Community Development Block Grants (CDBG) and the HOME Investment Partnerships Program (HOME). Therefore, the City does not have any resources for direct financial housing assistance, other than a small Affordable Housing Trust Fund. The City will provide referral information to extremely-low-, very-low-, low-, and moderate-income persons and families, the elderly, and persons with disabilities regarding affordable and special needs housing, such as Section 8 Rental Assistance and the Mortgage Credit Certificate program. If feasible, the City will seek CDBG and HOME funds.

a. Affordable Housing Trust Fund. Maintain an Affordable Housing Trust Fund and use the proceeds to leverage other sources of funding for affordable housing.

b. State and Federal Grants. Where feasible, seek state and federal grant funds, such as CDBG and HOME, in order to provide support for affordable housing activities.

c. Section 8 Rental Assistance. Provide referral information to low-income persons seeking rental assistance by publicizing the program in flyers posted at City Hall, the City's website and other public locations.

d. Mortgage Credit Certificates. Provide referral information regarding the mortgage credit certificate program to homebuyers by publicizing the program in flyers posted at City Hall, the City website and other public locations.

Responsible department: Planning Department; Housing Authority of Los Angeles County (HACoLA)
Funding source: General Fund; Section 8; mortgage credit certificates; Affordable Housing Trust Fund; CDBG/HOME (if feasible)
Time frame: The City's Housing Coordinator has responsibility for monitoring all activities related to Housing Element implementation, including preparation of annual progress reports, annual monitoring of sources of financial assistance such as Section 8, state/federal grants, and mortgage credit certificates. The Housing Coordinator shall also be responsible for disseminating information to the community regarding these activities and resources.
Depending on program availability and City eligibility, apply for state/ federal funds on a bi-annual basis to assist affordable housing development.
Objective: Disseminate housing assistance information; provide direct funding in support of affordable housing when feasible
  1. Housing Performance Monitoring
Policy 4.1 Monitor housing program results and revise strategies as necessary

Program 4.1 - Monitor and Report Annually on Housing Program Accomplishments

The City will monitor accomplishments toward Housing Element objectives and report annually to the City Council and California Department of Housing and Community Development. If implementation measures are ineffective in achieving desired results, adjustments will be made to improve the efficacy of programs.

Responsible department: Planning Department
Funding source: General Fund
Time frame: Annual progress reports
Objective: Monitor progress and make mid-course corrections if necessary to achieve desired results

Section III. Glossaries

Appendix A. Glossary of Terms.

The following glossary of terms is based on several sources. The sources for the glossary include the California Planning Roundtable, a nonprofit association affiliated with the California Chapter of the American Planning Association. In addition, the glossary also includes terms and definitions developed by the League of California Cities and the City of Calabasas.

The purpose of this glossary is to define the terms used to describe the City of Malibu's policy commitments.

Adaptive Reuse The conversion of an existing building from one type of use to another type of use. The purpose of adaptive reuse is to encourage retaining the primary constructed structure while minimizing new construction. Examples include, but are not limited to the following: (a) converting a church sanctuary to a performing arts theater; (b) converting an elementary school to an office complex; (c) converting a gas station to a restaurant; (d) converting retail space to residential uses; and other similar conversions. Adverse Impact A negative consequence for the physical, social, or economic environment resulting from an action or project. Adopt Action will be undertaken to formulate policy, guidelines, or ordinances or revisions thereto. The expectation is that resources would be devoted to creating the policy, guidelines, ordinances, or revisions, and that they will be formally enacted by appropriate City decision makers. Affordable Housing Housing capable of being purchased or rented by a household with very low, low, or moderate income, based on a household's ability to make monthly payments necessary to obtain housing. Housing is considered affordable when a household pays less than 30% of its gross monthly income for housing including utilities. Affordability Requirements Provisions established by a public agency to require that a specific percentage of housing units in a project or development remain affordable to very low-and low-income households for a specified period. Alluvial Soils deposited by stream action. Ambient Surrounding on all sides; used to describe measurements of existing conditions with respect to traffic, noise, air and other environments. Annex To incorporate a land area into an existing district or municipality, with a resulting change in the boundaries of the annexing jurisdiction. Applicant A person proposing development (see proposed development). Aquifer An underground, water-bearing layer of earth, porous rock, sand or gravel, through which water can seep or be held in natural storage. Aquifers generally hold sufficient water to be used as a water supply. Archaeological Relating to the material remains of past human life, culture, or activities. Articulation Variation in the depth of the building plane, roof line, or height of a structure that breaks up plain, monotonous areas and creates patterns of light and shadow. Avoid To keep away from, or to prevent the occurrence or effectiveness. Development in areas to be avoided will be subject to additional conditions requiring mitigation of the impact of that development on public services, facilities and resources. Areas to be avoided would be among those included in the last phase of a growth management study. Base Flood In any given year, a 100-year flood that has one percent likelihood of occurring, and is recognized as a standard for acceptable risk. Basic Biogeographic Planning Area A geographic area which is united by common biological and geophysical processes, which creates a natural planning unit for evaluating and implementing natural resource protection. The basic biogeographic resource planning area for the Malibu coastal zone is defined as the individual watershed. Biota All the living organisms of a particular area; the combined flora and fauna of a region. Blue Line Stream Those drainage pathways identified by a "blue line" on U.S.G.S. topographic maps. Bluff A cliff, head land or hill with a broad steep face. Buildout Development of land to its full potential or theoretical capacity as permitted under the provisions of the General Plan. Bulk Envelope The space remaining on a site for structures after all building setback, height limit and bulk requirements. California Environmental Quality Act (CEQA) A state law requiring state and local agencies to regulate activities with consideration for environmental protection. If a proposed activity has the potential for a significant adverse environmental impact, an Environmental Impact Report (EIR) must be prepared and certified as to its adequacy before taking action of the proposed project. Caltrans California Department of Transportation. Capital Improvement Program A budgetary program that schedules the construction of public facilities to fit its fiscal capability some years into the future. Capital improvement programs are usually projected five or six years in advance and should be updated annually. Carrying Capacity The level of land use, human activity, or development for a specific area that can be accommodated permanently without an irreversible change in the quality of air, water, land, or plant and animal habitats. Carrying capacity also refers to the upper limits beyond which the quality of life, health, welfare, safety or community character within an area will be impaired. Character Special physical characteristics of a structure or area that set it apart from its surroundings and contribute to its individuality. Circulation Element One of the seven State-mandated elements of a local general plan, it contains adopted goals, policies, and implementation programs (or measures) for the planning and management of existing and proposed thoroughfares, transportation routes, and terminals, as well as local public utilities and facilities, all correlated with the land use element of the general plan. Coastal Morphology The biological characteristics of the coastal area, including the relationships between terrestrial and marine plants and animals in the coastal zone. Commercial Strip Commercial development, usually one store deep, that fronts on a major street for a distance, usually one block or more. Includes individual buildings on their own lots, with or without on-site parking, and small linear shopping centers with shallow on-site parking in front of the stores. Common Open Space Land within or related to a development, not individually owned or dedicated for public use, which is designed and intended for the common use or enjoymen

a major street for a distance, usually one block or more. Includes individual buildings on their own lots, with or without on-site parking, and small linear shopping centers with shallow on-site parking in front of the stores. Common Open Space Land within or related to a development, not individually owned or dedicated for public use, which is designed and intended for the common use or enjoyment of the residents of the development. Community The recognizable unit of a given geographic area, produced by interaction of climatic factors, biota, and substrate, usually designated according to the characteristic adult or climax vegetation, such as deciduous forest, grassland, chaparral, and the like. Community Noise Equivalency Level (CNEL) A 24-hour energy equivalent level derived from a variety of single-noise events, with weighing factors of 5 and 10 dBA applied to the evening (7:00 p.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) periods, respectively, to allow for the greater sensitivity to noise during these hours. Composting The treatment of solid organic refuse through aerobic, biologic decomposition. Congestion Management Plan (CMP) A mechanism employing growth management techniques, including traffic level of service requirements, development mitigation programs, transportation systems management (TSM), and capital improvement programming, for the purpose of controlling and/or reducing the cumulative regional traffic impacts of development. AB 1791, effective August 1, 1990, requires all cities, and counties that include urbanized areas, to adopt and annually update a CMP. Conservation Element One of the seven State-mandated elements of a local general plan, it contains adopted goals, policies, and implementation programs for the conservation, development, and use of natural resources including water and its hydraulic force, forests, soils, rivers and other waters, harbors, fisheries, wildlife, minerals, and other natural resources. Coordinate Action will be taken to expend time and money in jointly pursuing an implementing activity with other entities. The expectation is that implementation will definitely result, and that it will be accomplished cooperatively with other organizations, possibly with the City in the lead. Cumulative Effect or Cumulative Impact "Cumulative impacts" refers to two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts. The incremental effects of an individual project are reviewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects. dB Decibel; a unit used to express the relative intensity of a sound as it is heard by the human ear. dBA The "A-weighted" scale for measuring sound in decibels; weighs or reduces the effects of low and high frequencies in order to simulate human hearing. Every increase of 10 dBA doubles the perceived loudness though the noise is actually ten times more intense. Dedication An action by a property owner which turns over private land for a public use, and its acceptance for such use by the government agency in charge of the public function for which it will be used. Dedications for streets, parks, school sites, or other public uses are often made conditions for the approval of a development. Density Transfer A process permitting unused allowable densities in one area to be used in another area. Where density transfer is permitted the average density over an area would remain constant, but allow internal variations. Within a single development, the result would normally be a clustering of buildings on smaller lots with some land retained as open space. Development The physical extension and/or construction of structures, subdivision of land, roads or other facilities, installation of septic systems; grading which requires a permit; and deposit of debris or fill materials. Additions to existing structures that do not exceed 10% of the original floor area, routine repair, maintenance and remodel are not "development." Development (Proposed) Development for which an application for approval/permits has been submitted to the City, but not yet approved. Dispersion A measure of the "scattering" of a component of water (e.g., pathogens or nitrates) in various directions. District

1. An area of a city or county that has a unique character identifiable as different from surrounding areas because of distinctive architecture, streets, geographic features, culture, landmarks, activities, or land uses.
2. A portion of the territory of a city or county within which uniform zoning regulations and requirements apply; a zone.
Disturbed Sensitive Resource Areas (DSRAs)
Those areas which would historically have met the Coastal Act definition of an environmentally sensitive habitat but which have been substantially modified as a result of coastal development. DSRs typically possess remnant biota which remain important biological resources.
Diversity Diversity
Differences among otherwise similar elements that give them unique forms and qualities, e.g., housing diversity can be achieved by differences in unit size, tenure, or cost.
Downzoning Downzoning
A change in the zoning classification of land to a classification permitting development that is less intensive or dense, such as from multifamily to single-family or from commercial to residential. A change in the opposite direction is called "upzoning."
Drainfield Drainfield
A means to finally treat and dispose of septic tank effluent by means of subsurface soil-absorption and adsorption. Also known as disposal field or leachfield.
Dwelling Unit Dwelling Unit
A room or group of rooms (including sleeping, eating, cooking and sanitation facilities, but not more than one kitchen), which constitutes an independent housekeeping unit, occupied or intended for occupancy by one household on a long-term basis.
Easement Easement
The portion of a property for which access or use is allowed by a person or agency other than the owner.
Easement, Conservation Easement, Conservation
A tool for acquiring open space with less than full-fee purchase, whereby a public agency buys only certain specific rights from the land owner. These may be positive rights (providing the public with the opportunity to hunt, fish, or ride over the land), or they may be restrictive rights (limiting the uses to which the land owner may devote the land in the future).
Ecology Ecology
The interrelationship of living things to one another and their environment; the study of organisms as affected by the factors of their environments.
Ecosystem Ecosystem
The fundamental unit in ecology, comprising the living organisms and the nonliving elements interacting in a certain defined area.
Effluent Effluent

Eminent Domain Eminent Domain
The legal right of government to acquire or take private property for public use or public purpose upon paying just compensation to the owner. While originally used only when land was to be kept in public ownership, i.e., for highways, public buildings or parks, property has been condemned under eminent domain powers for private use in the public interest, such as urban renewal.
Encourage Encourage
The action will receive positive treatment in written policy, and will be transmitted as appropriate to influence others. In cases where the City can compel action, such as in the application review process, the City will commit resources to assist others to achieve the action or condition being encouraged. The expectation is that, to the extent that the action or condition meets both the objectives of the City and the other party, that the action or condition will occur. In cases where the City cannot compel the actions of others, encourage is synonymous with support.
Endangered Species Endangered Species
A species of animal or plant that is considered to be endangered when its prospects for survival and reproduction are in immediate jeopardy from one or more causes. Both the California Department of Fish and Game (pursuant to Title 14 of the California Administrative Code) and the U.S. Fish and Wildlife Service (pursuant to the Federal Endangered Species Act) identify endangered species.
Endemic Endemic
A species or habitat type that is restricted to a particular geographic area or soil type and which occurs in no other area.
Encroachment Encroachment
Any obstruction or protrusion into a right-of-way or adjacent property, whether on the land or above it.
Enhance Enhance
To improve existing conditions by increasing the quantity or quality of beneficial uses or features. Action will be taken to improve existing conditions by increasing the quantity or quality of beneficial uses or existing actions. The expectation is that a desirable condition exists, and is to be improved by the action.
Ensure Ensure
Action will be taken to guarantee a certain outcome or result. The expectation is that, in guaranteeing a particular result, the City will commit resources, and has the legal right to compel other parties to take a particular action or perform in a prescribed manner.
Environmentally Sensitive Area or Environmentally Sensitive Habitat Area (ESHA)
Any area in which plant or animal life or their habitats are either rare or especially valuable because of their special nature or role in an ecosystem and which could be easily disturbed or degraded by human activities and developments. Malibu's ESHAs include, but are not limited to, the following:
1. Those areas designated as such on the Sensitive Environmental Resources and Marine Resources Maps.
2. Habitat for species and plant communities recognized as threatened or endangered by the state or federal governments; plant communities recognized by the State of California (in the Terrestrial Natural Communities Inventory) as restricted in distribution and very threatened; those habitat types of limited distribution recognized to be of particular habitat value including wetlands, riparian scrub, riparian woodlands, oak woodlands, and oak savannahs (Table 3-5).
3. Those areas designated by the County of Los Angeles as Significant Ecological Areas (SEAs) which meet the definition of environmentally sensitive habitat areas as defined in Section 30107.5 of the Coastal Act (Table 3-4).
4. Any areas which through professional biological evaluation meet the criteria enumerated in (2) and (3), above.
5. Those marine areas designated by the State of California as areas of Special Biological Significance (ASBS).

Fiscal Impact Analysis Fiscal Impact Analysis
A projection of the direct public costs and revenues resulting from population or employment change to the local jurisdiction(s) in which the change is taking place. Enables local governments to evaluate relative fiscal merits of general plans, specific plans, or projects.
Flood - 100 Year (Base Flood) Flood - 100 Year (Base Flood)
The magnitude of a flood expected to occur on the average every 100 years, based on historical data. The 100-year flood has a 1/100, or one percent, change of occurring in any given year.
Floodplain Floodplain
The land area on either side of the banks of a stream regularly subject to flooding from any source. That part of the flood plan subject to a one percent chance of flooding in any given year is designated as an "area of special flood hazard" by the Federal Insurance Administration.
Floor Area Ratio (FAR) Floor Area Ratio (FAR)
The gross floor area permitted on a site divided by the total net area of the site, expressed in decimals to one or two places. For example, on a site with 10,000 net sq. ft. of land area, a Floor Area Ratio of 1.0 will allow a maximum of 10,000 gross sq. ft. of building floor area to be built. On the same site, a FAR of 0.5 would allow 5,000 sq. ft. of floor area; an FAR of 0.25 would allow 2,500 sq. ft.; and an FAR of 0.15 would allow only 1,500 sq. ft. Also, as commonly used in zoning, FARs typically are applied on a parcel-by-parcel basis to an average FAR for an entire land use or zoning district.
"Granny Flats" "Granny Flats"
A secondary housing unit, no greater than 1,200 sq. ft. in floor area, developed on a residential lot or parcel for the purpose of providing additional affordable housing opportunities, typically for extended elderly family members. Granny flats include kitchen and bathroom facilities.
Grasslands Grasslands
Lands in which grasses are the predominant vegetation.
Greywater Greywater
"Wastewater" generated by household appliances and fixtures with the exception of the toilet, possibly the garbage grinder (garbage disposer), and non-bathing water bodies (jacuzzis, swimming pool, spas).
Ground Failure Ground Failure
Ground movement or rupture caused by strong shaking during an earthquake. Includes landslide, lateral spreading, liquefaction, and subsidence.
Ground Shaking Ground Shaking
Ground movement resulting from the transmission of seismic waves during an earthquake.
Groundwater Groundwater
Water under the earth's surface, often confined to aquifers capable of supplying wells and springs.
Groundwater Recharge Groundwater Recharge
The natural process of infiltration and percolation of rainwater from land areas or streams through permeable soils into water-holding rocks which provide underground storage ("aquifers").
Growth Management Growth Management
Policy for future growth to be controlled or otherwise regulated by various ordinances and programs. The land use element of the general plan identifies future growth, including both residential and nonresidential development. Growth management is a process, through ordinances and programs, to ensure that the growth identified in the general plan's land use element occurs at a pace consistent with the agency's objectives.
Habitat Habitat
The physical location or type of environment in which an organism or biological population lives or occurs.
Heritage Tree Heritage Tree
Any tree over 24 inches in dbh as a single truck or multiple trunks that cumulatively add up to 24 inches dbh.
Hillside Hillside
Land which has an average percent of slope equal to or exceeding 10%.
Home Occupation Home Occupation
A commercial activity conducted solely by the occupants of a particular dwelling unit in a manner incidental to residential occupancy.
Hotel Hotel
A facility offering transient lodging accommodations to the general public and providing additional services, such as restaurants and meeting rooms.
Households, Number of Households, Number of
The count of all year-round housing units occupied by one or more persons. The concept of households is important because the formation of new households generates the demand for housing. Each new household formed creates the need for one additional housing unit or requires that one existing housing unit be shared by two households. Thus, household formation can continue to take place even without an increase in population, thereby increasing the demand for housing.

Level of Service B : describes a steady flow of traffic, with only slight delays in vehicle movement and speed. All queues clear in a single signal cycle; the V/C is 0.61 to 0.70.
Level of Service C : denotes a reasonably steady, high-volume flow of traffic, with some limitations on movement and speed, and occasional backups on critical approaches; V/C is 0.71 to 0.80.
Level of Service D : denotes the level where traffic nears an unstable flow. Intersections still function, but short queues develop and cars may have to wait through one cycle during short peaks; V/C is 0.81 to 0.90.
Level of Service E : describes traffic characterized by slow movement and frequent (although momentary) stoppages. This type of congestion is considered severe, but is not uncommon at peak traffic hours, with frequent stopping, long-standing queues, and blocked intersections; V/C is 0.91 to 1.00.
Level of Service F : describes unsatisfactory stop-and-go traffic characterized by "traffic jams" and stoppages of long durations. Vehicles at signalized intersections usually have to wait through one of more signal changes, and "upstream" intersections may be blocked by the long queues; V/C is greater than 1.00.
