installation of PVC perforated pipe in pervious backfill material, grading of existing
ground, installing cleanouts and manholes, and restoring pavement along Polaris Drive,
Santiago Drive, Indian Springs Lane, and Spyglass Hills Road. The contract has now

resulted from an increase in the filter fabric required and in the amount of pavement
that had to be resurfaced. In addition, there was one change order totaling $1,451.45.
