*'''Vegetation''': Perform routine vegetation maintenance tasks (i.e., watering, weeding, trimming) at recommended frequencies (weekly or as required to maintain optimal soil moisture) over the two-year establishment period for the plantings; and replace plants that don't survive the initial establishment period (assumes 10% and 20% of plant material does not survive the first year for Minimum Recommended and High Frequency maintenance scenarios, respectively). Replacement of dead/diseased plants once established shall take place every 6 months or yearly dependent upon the minimum of 80% vegetation coverage. Remove any undesirable vegetation (invasive, seedlings etc.) every 3 - 6 months, and ensure proper pruning, cut back and thinning of shrubs and plants every year.

Replacement of dead/diseased plants as needed thereafter to maintain 80% vegetation coverage.
