' curt e order has two bask eleirtents; The first element is the star~m sewer outfall on This g . eta les street. Prior to the be ' of construction, the contractor did exploratory ~ ., vat~ons aloe the ro ased l~rte of the storm sewer to detei~irte if any existing ut~ty exca ~ p p ~n s would be in conflict v~ith the new storrrt sewer dome conflicts v~ere found.
