<br /> GENERAL INSTALLATION: The at-grade area is staked out along the design contour. Existing
<br /> vegetation is mowed and raked off the site. The basal area (L x W) is staked out and plowed with a
<br /> moldboard or chisel plow. Plowing may not proceed if the soil is wet enough at the plow depth to
<br /> form a 1/4 inch soil wire when a sample is rolled between the palms of the hands. The A x B area is
<br /> covered by clean aggregate deposited overhead by a backhoe. Special care must be used when
<br /> placing the aggregate to minimize compaction of the plowed surface. After the topsoil cap is placed,
<br /> the entire at-grade is seeded and mulched to promote vegetative growth, limit erosion and protect
<br /> from freezing. The observation pipes are perforated in the lower 6 inches and secured in place.
