D. GRADING AND EROSION CONTROL I. Prior to the approval of the first Final Map, the Subdivider shall submit all information including a Grading Plan accompanied by Soils Engineering and Engineering Geology Reports, in the accordance with requirements of the City of San Leandro Municipal Code Title VII, Chapter 12 and obtain a grading permit. 2. Prior to the commencement of any clearing, grading or excavation resulting in a land disturbance of five acres or more, the Subdivider shall submit evidence to the City or County that a Notice of Intent (NOI) has been submitted to the (California) State Water Resources Control Board. 3. The Subdivider shall comply with the regulations and provisions contained in the City's Grading Ordinance, the City's Storm Water Pollution Prevention Permit, and the National Pollutant Discharge Elimination System (NPDES), to the satisfaction of the City Engineer and the Regional Water Quality Control Board. 4. The Clean Water program requires that to filter and remove pollutants, impervious surfaces do not connect directly to the storm drain system and flow over grassed areas be increased. To comply with this requirement, redesign the courtyard homes to eliminate the field inlets and increase flow over grassed surfaces on the lots. It is also recommended that the engineer explore other methods of increasing flow through grassed and landscaped and/or use of pervious pavements where feasible. 5. The project Storm Water Pollution Prevention Plans (SWPPPs) shall include storm water pollution prevention and control measures for the operation and maintenance of the project during and after construction for the review and approval by the City Engineer. The SWPPPs shall identify Best Management Practices (BMPs) appropriate to the uses conducted on -site in order to limit to the maximum extent practicable the entry of pollutants into storm water runoff. 6. The plans shall also include erosion control measures to prevent soil, dirt and debris from entering the storm drain system, in accordance with the practices outlined in the ABAG Erosion and Sediment Control Handbook, California Storm Water Best Management Practice Handbooks, and the Regional Water Quality Control Board's Erosion and Sediment Control Field Manual. 7. Until such time as all construction for the development has been completed to the satisfaction of the City Engineer, the Subdivider shall provide current Erosion and Sediment Control Plans, and amended SWPPPs for all portions of the site where construction is ongoing. Said Plans shall be submitted to the City Engineer for review and approval on or before September 1 of each calendar year, and shall be fully implemented on or before October 15 of each calendar year.
