St. Dev. - Standard Deviation.NP - Non-plastic.

** - After review of the grain size distribution and the proximity of the sampled interval to the water table, it was determined that he coefficient of permability value for B-132 doesn't represent saturated formation conditions for the site.

St. Dev. - Standard Deviation.NP - Non-plastic.-- - Test not conducted for that sample.** - After review of the grain size distribution and the proximity of the sampled interval to the water table, it was determined that

he coefficient of permability value for B-132 doesn't represent saturated formation conditions for the site.

Ongoing outreach with community regarding goals and vision

Maintain silt fencing as a perimeter barrier to limit snake access into the construction area

Gradually draw down water to allow specie migration

Grubbing, excavation, construction
