Project No. 24006174A July 19, 2024 Page 2 | 9 42 Eagle Ridge Way. When the contractor was responding to the HEP SCD directive, he encountered two (2) 12” collapsed clay pipes at the outfall. The intention was to repair and improve this item as part of the cleaning and repair process, not to increase velocity existing at the outfall. The contractor believed that a flatter and wider pipe with a larger surface area should diminish the flow compared to dual 12-inch pipes.
