U1 PLANNING DEPARTMENT Attached for your review and approval is a dust control plan, a letter indicating the acerage to be disturbed and a letter from our archaeological service indicating they will be monitoring the site. It is our intent to have another contractor, World Development, remove dirt from our site starting October 5th and finishing around. the 19th of October. The contractor referred will be filing his own dust control plan and obtaining any stockpiling permit he needs. Our dust control plan is for the on -site dust control as the dirt is removed. The enclosed map illustrates where'the dirt will be removed from and this will be monitored by our civil engineer, RBF and L&L Environmental as per the City's request. I will be submitting a check for the fringe toed lizard fee for 6 acres as per our engineer's letter. The area where the dirtis being removed is to be our Phase II and we will be coming in shortly for a grading permit for that area after the dirt is removed. It is our,intent to keep the area wet and ready to grade for the few weeks from removal to permitting. Therefore we will not be using any sta-soil treatment on this area.

Approval of this dust control plan does not in and of itself constitute, or otherwise authorize any site disturbance, preparation or construction. The developer is required to ,obtain any and all necessary permits and clearances as set forth' in any development approvals issued and currently in effect . ' pertaining to this site. This includes any type of testing, monitoring or sampling required as a condition of development approval, such as that conducted for. archaeologic, hydrologic and geologic reporting purposes. 7. .� This -dust control approval 'does not cover the full range of Phase 2 grading, nor does it apply to any export activity undertaken off -site -by World Development. A separate FDCP approval must be issued for the balance of the area to be graded under 25953-2, .and to World Development to address the disposition' of the exported material. No export, of the subject material may occur until World Development satisfies Condition 10 below, and files a dust control plan on their own behalf. This approval is only for operations associated with the on -site aspects, of the export preparation and dust mitigation measures.' SITE DEVELOPMENT: -8.
