Is there a flood risk?

According to FEMA, in Williamson County 0.7% of homes (1,291) are in a high-risk flood zone. Of those homes, 46% have NFIP flood insurance.

  • A high-risk zone (Special Flood Hazard Area) has a 1% or greater chance of flooding each year. (44 CFR 59.1)
  • If the home is in that zone and the loan comes from a regulated lender, federal law requires flood insurance for the life of the loan, in communities that take part in the NFIP. (42 U.S.C. 4012a)
  • Most homeowners insurance does not cover flood damage. (FEMA, FloodSmart)

Climate and upkeep

Department of Energy (PNNL), 2021 IECC zones

The home energy code (IECC) puts Williamson County in zone 2A: hot and humid.

The zone's number says how hot or cold it gets; the letter says how humid: A is moist, B is dry and C is marine.

  • Spring

    • Book the air conditioner's check-up before the heat: ENERGY STAR advises checking the cooling system in the spring, because contractors get busy once summer comes. ENERGY STAR (EPA)
    • Clean and repair the roof gutters. EPA

  • Summer

    • Keep indoor humidity below 60 % (ideally between 30 % and 50 %). A humidity meter is inexpensive and sold at hardware stores. EPA
    • Keep the air conditioner's drip pan clean and its drain line flowing: a plugged drain can cause water damage in the house. ENERGY STAR (EPA)

  • Fall

    • Book the heating check-up in the fall. If it runs on gas or oil, the technician should check the connections: faulty ones are a fire hazard. ENERGY STAR (EPA)
    • Check that the ground slopes away from the house, so water does not collect around the foundation. EPA

  • Winter

    • Look for drafts at windows and doors: close the window on a piece of paper; if it moves back and forth easily, it needs thicker weather stripping. ENERGY STAR (EPA)
    • Seal the air ducts that run through the attic, crawlspace, basement or garage with duct mastic or foil tape, then wrap them in insulation. ENERGY STAR (EPA)

All year

  • Check the air filter every month, especially in heavy-use months. If it looks dirty, change it; change it at least every 3 months. ENERGY STAR (EPA)
  • Test the smoke alarms every month and replace their batteries at least once a year. USFA (FEMA)

Each task comes from the official page beside it. The spring air-conditioning and fall heating check-ups are the timing ENERGY STAR advises; the rest is a suggested order.
