26 of the 2,559 lots in Fircrest (1%) have septic records on file with the Tacoma-Pierce County Health Department. 68 lots are inside a Pierce County sewer service area, and 83 are within 300 feet of a county sewer main.
County sewer maps do not show sewers run by cities, so a lot inside a city may be on sewer even when no county main is nearby.
Septic records include permits, designs and inspections; older ones are on microfilm and are found by parcel number.
