Unknown authsoils

USDA NRCS Soil Data Access for soil properties and construction suitability. Soil properties affect foundation design, spill containment, and reclamation planning. CRITICAL USAGE RULES: 1. No authentication required - free government API 2. Query by area symbol (county code, e.g., TX201 for Harris County) 3. Returns drainage class, hydrology group, flood frequency 4. Use getInterpretations() for construction suitability ratings
