Irrigated bio-swales shall be redesigned as needed to the satisfaction of the City Engineer to optimize the amount of the storm water running off the paved surface that enters the bio-swale at its most upstream end. This plan shall be subject to the review and approval of the City Engineer prior to the issuance of any building permits; b) In addition to natural controls the project developer may be required to install a structural control, such as an oil/water separator, sand filter, or approved equal (in the parking lot) (on the site) to intercept and pre-treat storm water prior to reaching the storm drain. The design, locations, and a schedule for maintaining the separator shall be submitted to the City Engineer/Chief Building Official for review and approval prior to issuance of building permits. The structural control shall be cleaned at least twice a year: once immediately prior to October 15 and once in January. The project developer shall enter into a maintenance agreement for the oil/water separator; c) The project developer shall submit sizing designs criteria to treat stormwater runoff at the time of plan submittal; 12
