Glossary

A glossary of terms and acronyms you may encounter in our planning documents.

Access to Opportunity

Living within walking distance or with transit access to services, employment opportunities, education, amenities, and other key determinants of social, economic, and physical well-being. 

Affordable Housing

Commonly defined in terms of housing costs as a percentage of household income. Housing is considered unaffordable when a household’s monthly housing costs exceed a certain threshold – most commonly 30% of gross income – thereby reducing the budget available for basic necessities and other household expenses. 

Area Median Income (AMI)

The area median income (AMI) is the midpoint of a community’s income distribution, which means that 50% of the households in that community have a total, pre-tax income higher than the AMI and 50% of the households in the community have a total, pre-tax income lower than the AMI.   

Active Living

Promotion of physical activity, including walking and bicycling, to address health and personal well-being, focusing on how the built environment — including neighborhoods, transportation systems, buildings, parks and open space — can contribute to more daily movement and activity. 

Buildable Lands Analysis

An assessment of the amount of land needed for commercial, industrial, and housing development, as required by the Growth Management Act (RCW 36.70A.215). Buildable lands programs are to determine whether a county and its cities are achieving urban densities within the urban growth area by comparing adopted plans with actual growth. 

Built Environment

Refers to the human-created surroundings that provide the setting for human activity, ranging from large-scale civic districts, commercial and industrial buildings, to neighborhoods and individual homes. 

Comprehensive Plan

A local plan required by the state Growth Management Act to address land use, housing, transportation, utilities, and capital facilities, and other elements, to guide growth and development for a 20-year period (RCW 36.70A). 

Concurrency

A state planning requirement to

ensure that needed services and facilities are in place by the time development is completed and to be occupied, or that funding has been committed to provide such services within six years. 

Conservation

The management of resources – such as water and energy – in order to eliminate waste or maximize efficiency of use. 

Countywide Planning Policy

An adopted provision developed collaboratively between the county government and the local cities and towns within that county. Countywide planning policies provide a common framework for individual comprehensive plans prepared by each local jurisdiction.  

Displacement

The involuntary relocation of current residents or businesses from their current residence. 

Equity (also Social Equity)

All people can attain the resources and opportunities that improve their quality of life and enable them to reach full potential. Those affected by poverty, communities of color, and historically marginalized communities are engaged in decision-making processes, planning, and policy making.

Equitable Development & Equitable Growth

Public and private investments, programs, and policies in neighborhoods to meet the needs of marginalized populations and to reduce disparities, providing access to quality education, living wage employment, healthy environment, affordable housing and transportation.

Growth Management Act (GMA)

The Growth Management Act (GMA) is a series of state statutes, first adopted in 1990, that requires fast-growing cities and counties to develop a comprehensive plan to manage their population growth. It is primarily codified under Chapter 36.70A RCW, although it has been amended and added to in several other parts of the RCW.

important for maintaining fish and wildlife populations

over the long term

Include, but are not limited to, native and Indigenous

peoples, people of color, immigrants and refugees,

people with low incomes, those with disabilities and

health conditions, and people with limited English

proficiency.

Housing Affordability

Infill Development

Projects that use vacant or underutilized land in areas that were previously developed.

Jobs-Housing Balance

Joint Planning

Cooperative planning between two or more jurisdictions or agencies

Level-of-Service Standard

Measures of the minimum amount of a public facility that must be provided to meet that community’s basic needs and expectations. The Growth Management Act requires jurisdictions to establish LOS for transportation-related facilities (RCW

36.70A.070(6)(a)).

Mixed-Use Development

Projects or districts that include residential, commercial, and business accommodations. Vertical mixed-use development refers to buildings that have multiple uses in a single structure, such as ground-floor retail, offices, and residences. Horizontal mixed-use development refers to districts where zoning allows for different uses to be in adjacent buildings and complexes.
