A maximum of 215 locations are proposed, avoiding known burrow locations. Each hole will be up to 36" deep using an approx. 3" diameter auger or standard spade shovel. Samples of the topsoil and embankment material will be taken for laboratory soil index testing, visual observation, and in-place density tested using a portable nuclear gauge.
