ECO prepared several draft analyses of the alternatives and land use scenarios between September 1999 and March 2000. Those drafts were reviewed internally, by the Consortium, by the Technical Advisory Committees and Steering Committee, and by Constituent Groups. Those reviews resulted in several comments and suggested revisions to the assumptions underlying the draft analysis. Those comments have been addressed in the current versions of the Research Reports (December 2000), and are incorporated into this summary. 1.3 ORGANIZATION OF THIS SUMMARY The remainder of this Summary Report is divided into four sections: the first, Urban Development Patterns, describes the analysis that was used to create the two development alternatives and the results of the simulation of land consumption through the year 2050. The last three-Impacts on Farmland, Impacts on Forestland, and Infrastructure and Public Services Costs-describe how the two development alternatives affect the amount and production value of farm and forest lands, and the costs of providing certain types of urban services (e.g., sewer, roads). 2 URBAN DEVELOPMENT PATTERNS This section describes how we analyzed historical trends in residential density and development patterns to estimate how much land will be urbanized and how the UGBs will expand by the year 2050 for the two development alternatives for 2050: Page 4 December 2000 ECONorthwest DRAFT Summary Report |
