What FEMA's risk data says about Lakeside
FEMA rates San Diego County's hurricane risk as Very Low and its wind risk as Relatively Moderate.
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Lakeside home.
Ask specifically about design pressure and impact rating for Lakeside, not just energy performance, if either risk rating comes back on the high side.
