AGRICULTURAL LAND PRESERVATION AND NATURAL RESOURCE PROTECTION
SECTION 1. LAND CLASSIFICATIONS.
Subsection A. The following agricultural land classifications, determined from the Land Evaluation and Site Assessment (LESA) System as adopted for Marshall County, Iowa, are hereby established:
Land Classifications SA LESA "Low" Agricultural Value 0-172 0-151 "Moderate" Agricultural Value 173-188 152-254 "High" Agricultural Value 189-200 255-300
Subsection B. It is the intent of this Ordinance that land scoring between 255-300 points on the LESA System should be strongly encouraged for retention in agricultural use and/or non-agricultural development should be discouraged. It is the further intent of this Ordinance that R-1, R-2, R-3, C-1, and C-2 Districts should not be established on land scoring 255-300 points on the LESA System or where sensitive environmental conditions exist. Sensitive environmental conditions include, but shall not be limited to, areas of severe slope or erosion potential, flood hazard areas, mineral or other non-renewable resource areas, hydrologically sensitive areas, significant vegetation, soils with severe limitations to development or other natural features which would indicate that uses and densities permitted would be inappropriate.
Subsection C. Determinations of sensitive environmental conditions shall be made with reference to the Soil Survey of Marshall County, Iowa (issued September, 1981), the Critical Resource Overlay Map (1995) and the Marshall County Comprehensive Land Use Plan.
