Residents warn council Cumberland Aggregate Mine could bring heavy truck traffic and water use

Julius Stevens, an unincorporated King County resident, told the Eden Plus City Council the proposed Cumberland Aggregate Mine and asphalt plant would affect Enumclaw and surrounding communities and urged the council to review King County materials and submit comments before the county’s comment deadline. Stevens said the proposal anticipates 25–35 years of gravel removal and warned of significant traffic impacts if the mine proceeds.

"If you're looking at throwing approximately 298 to 668 heavy trucks per day into that traffic mode, it's going to complicate the life in Enumclaw," Stevens told the council, and he cited projected 24/7 operations and daily water needs "175,000 to 250,000 gallons a day" for the operation. Linda Stevens, another resident, urged preserving roughly 990 acres north of Cumberland (Lizard Mountain area) for recreation and expressed concern about potential impacts to private wells. Both speakers encouraged the city to review King County's materials; Stevens noted the county comment period runs through August 7.
