The Costco Wholesale warehouse and gas station are located on an 11-acre site within the Chino Hills Marketplace. Costco Wholesale Corporation has submitted a Conditional Use Permit No. 19CUP04 to allow the relocation and expansion of the existing Costco gas station. Costco proposes to add approximately 19,500 square feet to the existing Costco warehouse building to accommodate an employee locker room, new food service and sales area.
The proposed project would decommission the existing 12 pumps Costco gas station located in the northwest area of the Costco parking lot within the Crossroads Marketplace Shopping Center. The former Sports Chalet building would be demolished and Costco would retain a portion of the Sports Chalet site to construct the new gas station facilities. After demolition of the existing 42,000 square foot Sports Chalet building, there would be a net reduction at the overall mall of approximately 22,500 square feet.
The new gas station would consist of 16 pumps (32 fueling stations). The number of Underground Storage Tanks (USTs) would remain the same as proposed in the approved project but the location on the site would be different.
The existing gas station would remain in operation until construction of the new gas station has been completed and then the existing gas station will be decommissioned and demolished. The area occupied by the existing gas station will be converted to new parking and landscape planters.
The Costco parking lot would also be reconfigured for better internal circulation. The modified project would include grading and repaving of portions of the Sports Chalet property in addition to the existing Costco property. Parking required for the Costco warehouse and related facilities per the City’s standards is 550 stalls. Currently, 672 parking space are provided and the proposed project would result in 845 parking spaces.
