Generally, vegetation accounts for less than 15% of total cover.ĭeciduous Forest- areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. Impervious surfaces account for 80% to 100% of the total cover.īarren Land (Rock/Sand/Clay) - areas of bedrock, desert pavement, scarps, talus, slides, volcanic material, glacial debris, sand dunes, strip mines, gravel pits and other accumulations of earthen material. Examples include apartment complexes, row houses and commercial/industrial. These areas most commonly include single-family housing units.ĭeveloped High Intensity-highly developed areas where people reside or work in high numbers. Impervious surfaces account for 50% to 79% of the total cover.

These areas most commonly include single-family housing units.ĭeveloped, Medium Intensity -areas with a mixture of constructed materials and vegetation. Impervious surfaces account for 20% to 49% percent of total cover. These areas most commonly include large-lot single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes.ĭeveloped, Low Intensity- areas with a mixture of constructed materials and vegetation.

Impervious surfaces account for less than 20% of total cover. Perennial Ice/Snow- areas characterized by a perennial cover of ice and/or snow, generally greater than 25% of total cover.ĭeveloped, Open Space- areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses. Open Water- areas of open water, generally with less than 25% cover of vegetation or soil.
