Key Highlights
Is the French drain helping or hurting the slope?
Hurting. Runyan testified the French drain is "counterproductive" because it reintroduces water into the subsurface of the slope, destabilizing it.
Pages 24-25
What caused the slope to fail?
Water saturation. Runyan stated the cause was water saturation of the slope, and that rain data alone "does not define what caused it."
Pages 17-19
Did GeoTek recommend fixes? Were they done?
Yes, GeoTek made two recommendations: (1) cap the surface drains with a watertight cap, and (2) build a swale or v-ditch to redirect surface water. Neither has been implemented by the HOA.
Pages 25-26
Is the ponding and seeping on the slope a problem?
Yes. Runyan called it "a major contributing factor" to the slope instability.

Did GeoTek tell the HOA about the drainage issues?
Yes. Runyan testified that GeoTek emphasized drainage maintenance to the HOA "multiple times."
Pages 26-27
Did the HOA's attorney challenge the French drain finding?
He tried. During cross-examination, defense counsel attempted to distinguish "introduced" vs. "reintroduced" water. The exchange backfired and reinforced that the drain is sending water back into the slope.
Pages 36-37
Did GeoTek install the French drain?
No. GeoTek confirmed they did not install the French drain. The HOA installed it in 2019 without any geotechnical input.

Does this contradict the HOA's expert, Dr. Huang?
Yes. Dr. Huang testified there was "no need to disconnect" the drain. Runyan, the licensed civil engineer who actually investigated the site, says it is counterproductive and should be capped.
