Our transcription: Normally a landslide can be mitigated either by being removed or through the construction of some form of support.
But if core samples and other data obtained during drilling reveal that landslide activity here has been more extensive than anticipated or extends beyond the property line, mitigation efforts might prove impossible.
When we leave the field we'll take the information that we've gained and plot that information both in map form and cross section form.
Based on those cross sections, we will have our engineering staff evaluate the stability of proposed cut slopes, any removals which will be necessary of landslide areas, such as these.
Having analyzed their data, Meeker and her colleagues will present their final recommendations to the client.
It turns out that the news is both good and bad.
The bad news is that there is evidence of landsliding that crosses over to the adjacent property, and because the developer has no legal right to mitigate problems that are not on his land, some of the homes in the tract cannot be built.
The good news is that with careful grading, the right drainage, and use of vegetation, the rest of the homes can be built.
And residents of this housing tract will probably not have to worry about any major mass wasting problems.
