Elder Bench Protocol

A covenant of measurement: preserving the seats where our elders sit, against the rising tide of the Comal.

"We do not build walls to hold back the water. We raise the bench to meet the memory."

I. The Physical Specimen

The original Sophienburg bench, forged in 1935, stands at elevation 612.4 ft AMSL. Its seat height, worn smooth by seventy generations, is 18 inches from the deck plate.

Bench Dimensions (Original)

Seat Height18.0 in (457 mm)
Deck Plate Elev612.4 ft AMSL
MaterialCypress (Taxodium distichum)
Load Capacity450 lb (distributed)
Flood Line (1935)+7.8 ft from deck

II. The Hydrologic Constant

From our Floodline Predictor, we derive the critical alpha coefficient: α = 0.047 ft/inch. For every inch of rainfall upstream, the Comal rises 0.047 feet at the Sophienburg bend.

Prediction Constants

Alpha Coefficient0.047 ft/inch
Critical Threshold617.1 ft AMSL (seat overflow)
Rainfall Margin100.0 inches (safe zone)

III. The Preservation Algorithm

To maintain the sanctity of the bench, we apply the following protocol:

  1. Measure: Current deck elevation via USGS gauge station 08184500.
  2. Calculate: ΔH = (Current Rainfall × 0.047) − Safe Margin (2.0 ft).
  3. Act: If ΔH > 0, initiate Bench Lift Sequence (hydraulic jacks at 4 corners).
  4. Verify: Seat height remains 18 inches from new datum.
"The bench moves, but the story stays still."
