Annexation Factors


Ranking Factors

  • Septic System Failures – Ranking is based on percent of developed parcels within a designated Annexation Area that have with recorded septic system repairs. A higher percentage of failures = a higher short- term demand = a higher ranking.
  • Age of Structure – Based upon average age of structures within each Annexation Area. For future sewer extension projects, larger areas have been broken down into sub- areas, using Age of Subdivision as a ranking. Older subdivisions receive higher ranking, based upon useful life of septic systems and seniority.
  • Percent of Non- Sewered Improved Lots – Areas were ranked by identifying all lots 2 acres or less in size with a current building value greater than or equal to $10,000 that are not served by public sewer systems. A high percentage of non-sewered improved lots will typically result in more requests for sewer over a shorter period of time.
  • Developed Density – Areas were ranked by the total acres of improved lots divided by the total acreage of the Project Area parcels. Lower densities of developed property should result in lower short- term demand for sewer, with long- term demand primarily coming from developers.


Future Considerations

  • These preliminary analyses may be directly impacted by specific factors that cannot be quantified at this time. These additional factors will be integrated into PWC’s final utility extension considerations and decisions.
  • Financial considerations will have a direct relationship to the number and size of PWC utility extension projects that are scheduled each year. Annual budget demands, interest rates, bond availability, and potential grant funding will have to be reviewed on a continuous basis.
  • Natural (or other) disasters can delay extensions projects until recovery efforts are completed. Hurricanes, tornadoes, droughts, flooding, treatment plant problems, etc. can cause project schedules to change significantly.
  • Other factors as yet undetermined.
