Contractor shall verify all quantities ofgroundcovers by area calculations and spacing requirements.10.Landscaping is to be per plan. Plant substitutions due to availability or otherwise will be allowed onlywith landscape architect, owner and agency approval. Any substitutions will be with material of similarsize, growth characteristics, and quality.11.All trees must be staked as necessary so as to maintain material in a healthy, vigorous growingcondition.12.Landscaping shall be installed in a professional workmanlike manner that is consistent and acceptedthroughout the industry.

Street trees shall not be topped pollarded, or otherwise pruned in a mannercontrary to these goals, unless there is no practicable alternative that would preserve essential utilityservices.20.Plant material selected is drought tolerant or native species. The project proponent shall beresponsible for maintaining and watering all plant material throughout the first growing season andin times of drought. Temporary irrigation shall be provided via TREE GATOR BAGS attached toeach tree.
