The Construction entrances will use 36th street to access the property. Where necessary crushed surfacing base course shall be applied immediately after grading roadway areas.Alternate construction access BMPs are included in Appendix C as a quick reference tool for the on-site inspector in the event the BMP listed above is deemed ineffective or inappropriate during construction to satisfy the requirements set forth in General NPDES permit (Appendix D).To avoid potential erosion and sediment control issues that may cause a violation of the NPDES Construction Stormwater permit,the Certified Erosion and Sediment Lead will promptly initiate the implementation of one or more of the alternate BMPs listed in Appendix C after the first sign that existing BMP are ineffective or failing. 3.1.3 Element#3—Control Flow Rate In order to protect properties and waterways downstream of the project site, stormwater discharge from the site will be controlled. The specific BMPs for flow control that may be used on this project include: BMP C241:Temporary Sediment Pond BMP C207: Check Dams Check dams may be installed within all on-site temporary interceptor swales as needed. The check dams will slow down any flows occurring within these swales.Alternate flow control BMPS are included in Appendix C as a quick reference tool for the on-site inspector in the event the BMP listed above is deemed ineffective or inappropriate during construction to satisfy the requirements set forth in General NPDES permit(Appendix D).To avoid potential erosion and sediment control issues that may cause a violation of the NPDES Construction Stormwater permit,the Certified Erosion and Sediment Lead will promptly initiate the implementation of one or more of the alternate BMPs listed in Appendix C after the first sign that existing BMP are ineffective or failing. In general, discharge rates of stormwater from the site will be controlled where soil compaction during construction could lead to downstream erosion,or wherever necessary to meet local agency stormwater discharge requirements (e.g. discharge to a combined sewer systems). 3.1.4 Element#4 Install Sediment Controls All stormwater runoff from disturbed areas shall pass through an appropriate sediment removal BMP before leaving the construction site. The specific BMPs to be used for controlling sediment on the project include: BMP C220: Storm Drain Inlet Protection 7
