DRAFT LAND USE ANALYSIS FOR ANOKA COUNTY SITES INTRODUCTION The purpose of this land use analysis is to document the progression of property development surrounding the Oak Grove, Ramsey, and Andover landfill sites over a time period spanning landfill operations. This data can then be used to determine whether proximity to landfill operations is associated with differences in overall levels of such development. In general, given public concerns about landfills one could expect a landfill to restrict land use development quite strongly. Signifi~-ant proportional differences in development could be expected between the zones near the site and those furthest away. Twenty percent differences between near and far zones would likely be necessary to be sure of an effect given the vagaries of land use development. METHODOLOGY Metropolitan Council air photos at 1" = 200" were available for 1970, 1978, and 198q. These appeared to approximate the time sequence envisioned in the study, since they covered the period of activity of these landfills. A land use interpretation of designated categories was estimated, by acres, on a 40 acre (1/4 - 1/q section) grid for the existing landfills in Ramsey, Andover, and Oak Grove. Each 40 acre area was analyzed for the thirteen separate categories indicated below. The housing units for each grid cell were counted as well. The data was summarized by four concentric bands around each landfill. These are defiped as follows: Zone 1 less than 1/4 mile (all adjacent 40 acre grid cells) Zone 2 - 1/~ to 1/2 mile Zone 3 - 1/2 to 1 mile Zone 4 - 1 to 1 1/2 mile These bands were chosen following review of previous studies. It was expected that land use would be more subject to impact than property values, since land use changes imply significant one-time investment decisions, compared to the purchase of a single home. For this reason, and budget restraints, the number and extent of zones is thus smaller than for the hedonic model analysis.
