Land Use Change In Bellingham 1898-1997 Paul Anderson, Adam Bailey, Amy Hamlin, Parker-Leigh Juby, Nicholas LaRue ABSTRACT: Bellingham, Washington has experienced dramatic land use change over time. At the turn of the 19th century, forestry, mining and fishing were the dominant forms of land use. In the early 19th century population growth led to more intensive use of these dominate resource extraction industries. Pre-World War II through the subsequent baby boom saw a steady increase in urbanization, leading to development and high-density urban sections. This pattern of urbanization has continued and today high-density urban areas dominate Bellingham. This poster shows spatial-temporal land use changes in Bellingham using five categories: Water, Forest, Agriculture, Low-Density Urban, and High-Density Urban. A grid consisting of 1000-foot squares was placed over the current Bellingham city limits. If a grid’s land use consisted of more than 50% of a specific land use, the grid was assigned that land use code. Low-density urban was defined as 5 buildings or less, high-density urban was classified as greater than 5 buildings. Results: 1898 The results of our analysis can be seen by examining the maps and air photos to the left and the table below. Land Use Percentages within Bellingham’s City Limits 1916 1943 1898 1916 1943 1966 1984 1997 Water 10.02 5.46 9.44 9.34 9.70 3.47 Forest 90.48 76.06 45.55 25.92 17.34 7.67 Agriculture N/A N/A 9.53 5.43 5.82 12.00 LowDensity N/A 18.48 12.97 20.54 16.50 13.00 HighDensity N/A N/A 22.51 38.77 50.59 63.57 Discussion: The maps, aerial photos, and table on this poster show how land use has changed over time in Bellingham. Increased development and urbanization reinforce why sustainable planning is important to minimize the negative effects associated with urbanization. 1966 View of downtown from Sehome Hill 1929 (Courtesy of Whatcom Museum). Introduction: The purpose of this project was to discover how land use has changed within the current city limits of Bellingham, Washington from 1898 to the present. Base maps and aerial photographs with a time interval of approximately twenty years (1898, 1916, 1943, 1966, 1984 and 1997) were scanned to analyze land use change. The analysis put the data into five classifications: high and lowdensity urban, agriculture, forest, and water. The main focus of the project is on the series of maps showing the land use/land cover change over time. 1984 A view Bellingham looking East towards Mt. Baker Acknowledgements: Methods: Base maps from 1898 and 1916 as well as air photographs from 1943, 1966, 1984, and 1997 were scanned, georectified, mosaiced, and assigned land use classification codes. The land use codes were then assigned different colors to differentiate between the different codes. The land use classification codes were high and low density urban, agriculture, forest, and water. 1997 We would like to thank Kerry Lageuex for all his patience and help throughout the duration of our project. We would also like to thank Janet Collins for all of her knowledge and help with the background research and data acquisition. Thanks to Stefan Freelan and Steve Walker for the help with Arc/Info.
