The comments below were generated from this project's City of Everett Industrial Pretreatment Reviewer. All questions shall be routed through this project's Public Works Reviewer Thad Newport with City of Everett Permit Services (TNewport@everettwa.gov). # Document Sht/Pg Reviewer's Comment Designer's Response Initials City Comment: With the installation of downturned elbows on the outlet of both of the 1000 gallon OWS', this will satisfy this comment. 3 Civil Plans - 2"d Review Comment: The berm around the east fuel island An asphalt berm has been added along the (Pacific Pride) will need to be redone and surround the entire east and north edge of concrete pad fuel island to prevent stormwater from reaching the catch basin (Construction Note 10). Stormwater runoff on the southwest corner of the fuel island. The areas outside of along the east edge will flow south, the bermed area will need to be sloped such that it will not be following the road grade. Stormwater able to flow over the berm and into the fuel island area. (EMC runoff north of the concrete pad will drain 14.40.050.B.12) west and then north in the existing asphalt Designer's Response: Currently all surface runoff is collected by Swale. The asphalt berm will prevent the existing onsite catch basins that discharges to the private stormwater from flowing onto the concrete storm along the west property line. The Pacific Pride fuel island pad, per request. catch basin has a tributary area of approximately 1,460 square feet. There is approximately 460 square feet of open concrete pad between the fuel island and the 7th Avenue SE right-of-way line. Drainage from the Pacific Pride fuel island flows through a 11000 gallon OWS prior to discharging from the site. According to OWS sizing charts a 188-gallon volume structure would be required for water quality treatment. The final design proposes to revise the existing drainage piping to convey the 1,460 square feet of Pacific Pride tributary drainage area to the sanitary sewer via usage of the 4,500 gallon containment tank. The combined peak flow proposed (in gpm) to enter the sanitary sewer are provided with the submittal. The proposed berm is not necessary to control this drainage area. City Comment: The current berm in place at the east fuel island (Pacific Pride) is not sufficient to prevent stormwater from outside of the concrete pad from entering the catch basin at the southwest corner of the concrete pad. Currently, the berm only exists at the southern end of the pad. The berm must be expanded/redone to fully encompass the entire pad to prevent Page 3 of 8
