Category 1A Condition II This type of survey refers to specific code in the Texas Society of Professional Surveyors Standards and Specifications. A Category 1A condition denotes a survey in which all corners must be staked, or identified, to provide the least amount of deviation in the survey. A condition II survey means it is conducted in an ‘Urban’ setting, meaning within the limits of an incorporated city; however, this excludes a recognized downtown business district.
