Key Issues
Introduction
FLM 1- Methodology
Time Frame: 1980-2000 and 2000-2030
Historic Trends: An analysis and comparison of changes in land use
acreages over timeCrop and Pasture and developing
lands
Projections: An analysis of future land demand based on population
projections and land use trends and policies.
FLM1- Methodology
Data LimitationsDifferent interpretations of aerial photographsChanges in technology
•2000 used GIS, previous land use inventories did not.-Total area of Dane County in the 2000 land
use inventory is 6,514 acres greater than previous inventories.
-Water bodies and roads were measured more accurately.
Methodology
Data LimitationsChanges in metrics
In 1980 and 1990 farm dwellings were counted as residential land use, whereas in 2000 they were categorized as agricultural land uses.
Some woodlands located on land containing private agricultural operations were counted as agricultural uses prior to 2000.
Prior to 2000, pasture lands were included in crop/pasture.
Methodology
Data LimitationsChanges in land use classification
In 2000, all agricultural land within urban service areas was categorized as vacant/unused in 2000.
In 1990, farm ponds were counted as agricultural use, whereas in 2000 farm ponds were measured separately and categorized as water.
Major Findings1980-2000
Quantity •Approximately 95,000 acres of crop and pasture were converted to other land uses.
–Max. 37,000 of these acres may have been lost to development across cities, villages, and towns.
•37,000 acres of development county-wide.–Residential development is the largest contributor to losses in agricultural and undeveloped land (18,000 acres).
•24,000 acres of land were annexed by villages (8,000 acres) and cities (16,000 acres).
Major Findings2000-2005
Quality
10,000 acres of prime farmland were developed between 2000 and 2005.
Rural jurisdictions 3,000 acres
Service areas 7,000 acres
Major Findings2000-2030
Projections•As of 2000, 42,4501 acres will be needed by 2030 to
accommodate population growth based on past population and development trends.
•Service areas (Central and outlying service areas, including limited service areas) are anticipated to accommodate about 63% or roughly 26,750 acres of the land demand.
•Rural areas will accommodate the remaining 37% or 15,700 acres.
1 A portion of this acreage could be absorbed in existing developed areas on vacant or underutilized lands and may not require conversion of new agrilculral lands to developed uses.
