Add FES elevations for FES 3 and FES 5. 5. The maximum slope should not exceed one foot vertical to four feet horizontal. The slopes on pond slopes and berms appear to be one foot vertical to three feet horizontal. 6. The lot grading table should include the style of structure, the front yard slope, the rear yard slope, and a notation on which lots have yard grades less than 2% which will require a grading certificate prior to occupancy. 7. The tree preservation boundary should be added to the grading plan. 8. A permit from the Lower Rum Pdver Water Management Organization must be obtained for Bmokfield Second Addition. Utilities: This subdivision will be served by municipal sanitary sewer and water service which will be extended to the site via a separate contract. Service to tiffs subdivision will be dependant upon this contract and the development of the Sweet Bay Ridge and Broolcfield Addition subdivisions. Certificates of occupancy will not be issued until the City sanitary sewer and watermain are fully functional and must include permanent vehicular access to the lift station. The final construction plans submitted provide for only, one connection to the water supply. Fire flow demands will not meet minimum requirements without a looped water system provided to this development, nor will it provide a necessary second, connection to provide system reliability. -268-
