To delineate agricultural lands of local, statewide, and national importance in Boulder County

How was the data set created?

  1. From what previous works were the data drawn?

    (source 1 of 1)
    Type_of_Source_Media: paper
    Source_Scale_Denominator: 50,000
    From the Boulder County Comprehensive Plan: "In 1978, the state and county classified, identified and mapped the lands in the Plains portion of the county as to their potential agricultural productivity and significance. In order of significance, those mapped designations are "Lands of National, Statewide and Local Importance," as well as "Other Agricultural Lands." The new Agricultural Element includes an updated Agricultural Lands Map of the Boulder County Comprehensive Plan which was last approved in 1978 which was prepared by the Natural Resources Conservation Service, formerly the Soil Conservation Service. The methodology employed in the updating involved using 1995 aerial photography (color slides) on a scale of eight inches to the mile. The data from the slides was transferred to the Boulder County Zoning Maps and then overlaid on the Soil Conservation Service original Prime Farmland Map. The same basic criteria was used as when the map was originally prepared [described in the Environmental Resources Element approved in 1986]. There was, however, a change in some of the soils information that brought some additional lands into the ‘prime’ classification. This change was not drastic. Irrigation is one of the main criteria in determining if the soils are considered ‘prime’ and this was the principal area looked at in revising the map. Areas that have had a major change in land use or are no longer being irrigated were excluded from the ‘prime’ classification. The Environmental Resources Element of the Boulder County Comprehensive Plan provides more information on the methodology and criteria used in the mapping of the Significant Agricultural Lands."
