creates and /or replaces 10,000 square feet or more of impervious surface, <br />including roof area, street, and sidewalk. <br />b. Compliance with a Diazinon pollutant reduction plan (Pesticide Plan) to <br />reduce or substitute pesticide use with less toxic alternatives. <br />c. Compliance with a Copper Pollutant Reduction Plan and a Mercury Pollutant <br />Reduction Plan. <br />2. The following requirements shall be incorporated into the project: <br />a. The project developer shall submit a final grading and drainage plan, <br />including stormwater treatment calculations, prepared by a licensed civil <br />engineer depicting all final grades, onsite drainage control measures, and bio- <br />retention swales. Irrigated bio- retention swales shall be designed to <br />maximize stormwater entry at their most upstream point. The grading and <br />drainage plans shall be subject to the review and approval of the City <br />Engineer prior to the issuance of a grading or building permit, whichever is <br />sooner. <br />b. In addition to natural controls, the project developer may be required to install <br />a structural control(s), such as an oil /water separator(s), sand filter(s), or <br />approved equal(s) in the parking lot and /or on the site to intercept and pre- <br />treat stormwater prior to reaching the storm drain. The design, location(s), <br />and a schedule for maintaining the separator shall be submitted to the City <br />Engineer/Chief Building Official for review and approval prior to the issuance <br />of a grading or building permit, whichever is sooner. The structural control <br />shall be cleaned at least twice a year (once immediately prior to October 15 <br />and once in January). <br />c. The project developer shall submit to the City Engineer the sizing design <br />criteria and calculations for Trash Capture Devices (TCDs), and for the <br />treatment of stormwater runoff. The design criteria and calculations shall be <br />subject to the review and approval of the City Engineer and shall be <br />submitted prior to the issuance of a grading or building permit, whichever is <br />sooner. <br />d. Building /Structures shall be designed to minimize the occurrence and entry of <br />pests into buildings, thus minimizing the need for pesticides, as determined <br />by the Chief Building Official prior to the issuance of a building permit. <br />e. The project's landscape and irrigation plans shall be designed to: 1) minimize <br />the use of fertilizers and pesticides that can contribute to stormwater pollution; <br />and 2) promote surface infiltration. Prior to the installation of project <br />landscaping and irrigation, the project landscape architect shall submit a <br />landscaping and irrigation plan to the City Engineer for review and approval <br />and submit written verification stating the project incorporates the following: <br />PUD -106, Chrylser- Jeep -Dodge Page 34 <br />
