Which aspect does NOT typically factor into the evaluation of OSSF sites?

The evaluation of On-Site Sewage Facilities (OSSF) sites involves a variety of factors that ensure the safety and effectiveness of sewage disposal systems. Lot history and previous use are not typically primary considerations in the standard evaluation process.

Flood hazard information is crucial because understanding whether a site is prone to flooding can influence the installation and design of sewage systems to prevent potential backups or contamination. Soil texture analysis is also significant as it determines how well the soil can absorb and filter wastewater, which directly affects the system's performance. Similarly, setbacks and separation distances are essential regulations that ensure a safe distance between the sewage system and potential sources of contamination, such as water supplies and property lines.

In contrast, the history of the lot may provide some contextual information but usually does not influence the immediate technical factors necessary for evaluating site suitability for an OSSF installation. Therefore, it is not typically factored into the initial site evaluation, making it the correct answer to the question.
