NO BASE FLOOD ELEVATION DETERMINED. 1. Prior to any ground disturbance on the site one inspection with LDAP staff is required. Issuance of this plan does not relieve the permit holder and or the contractor from all other permitting requirements. Prior to beginning construction activities, all other necessary approvals shall be obtained. 2. The erosion and sediment control measures shown on the plan are the minimum requirements for anticipated site conditions. During the construction period, these measures shall be upgraded as needed for unexpected storm events and to ensure that sediment and sediment-laden water does not leave the site. 3. The implementation of the ESCP and the construction, maintenance, replacement, and upgrading of the erosion and sediment control measures is the responsibility of the permit holder and or the contractor until all construction is completed and accepted and vegetation / landscaping is established. 4. The boundaries of the clearing limits shown on this plan shall be clearly flagged in the field by the engineer prior to construction. During the construction period, no disturbance beyond the flagged clearing limits shall be permitted. The flagging shall be maintained by the permit holder and or the contractor for the duration of construction. 5. The erosion and sediment control measures on active sites shall be inspected and maintained daily and within the 24 hours after any storm event of greater than 0.5 inches of rain per 24 hour period. Measures shall be inspected by the permit holder and or the contractor after each rainfall and at least daily during prolonged rainfall. Any required repairs or adjustments shall be made immediately. The erosion and sediment control measures on inactive sites shall be inspected a minimum of once every two (2) weeks or within 48 hours following a storm event. 6. All erosion and sediment control measures shall be protected from damage at all times. Control measures shall remain in place until permanent re-vegetation has been stabilized. Any measure that is damaged or destroyed shall be repaired or replaced immediately. 7. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the wet season (October 1 to April 30) or seven days during the dry season (May 1 to September 30) shall be immediately stabilized with an approved ESC method (seeding & mulching with straw, bark, compost, or plastic covering, ect.). 8. Street sweeping shall be performed as needed or when directed by the City inspector to insure public right-of-ways are kept clean and free of debris. Street flushing is prohibited. 9. When trucking saturated soils from the site, either water-tight trucks shall be used or loads shall be drained on site until dripping has been reduced to no more than one gallon per hour. Sediment laden water will not be allowed to enter the storm water system 10. Extracted ground water from excavated trenches shall be disposed of in a suitable manner without damage to adjacent property, City's storm water system, water features, and related natural resources. Approval of a dewatering system does not guarantee that it will meet compliance or be acceptable for use in all situations. Modifications to the dewatering system will be required if compliance can not be met. At no time will sediment laden water be allowed to leave the construction site. 11. A supply of materials necessary to meet compliance and implement the LDAP or other best management erosion practices under all weather conditions shall be maintained at all times on the construction site. 12. No hazardous substances, such as paints, thinners, fuels and other chemicals shall be released onto the site, adjacent properties, or into water features, the City's storm water system, or related natural resources. 13. The ESC facilities shall be inspected daily be the contractor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (October 1 to April 30) and of monthly reviews during the dry season (May1 to September 30). Call 736-1037 for information. LDAP NOTES A. Approval of this Erosion and Sedimentation Control Plan (ESCP) does not constitute an approval of permanent road or drainage design (e.g., size and location of roads, pipes, restrictors, channels, retention facilities, utilities, etc.). B. The implementation of this ESCP and the construction, maintenance, replacement, and upgrading of these erosion and sediment control (ESC) facilities is the responsibility of the contractor until all construction is approved and the project is accepted by the City. C. In the event the ESC facilities identified on the ESCP are not functioning properly, the contractor is responsible for immediately implementing changes to the ESCP as directed by the ESCP engineer or his inspector. The engineer, his inspector or the City may stop all construction activity on site until the erosion problem is corrected and all ESC facilities are functioning properly. If the contractor does not immediately implement changes to the ESCP identified by the ESCP engineer or his inspector, the City may implement the necessary changes and requireay from the contractor prior to project acceptance by the City. D. The boundaries of the clearing limits shown on this plan shall be clearly flagged by a continuous length of survey tape (or fencing, if required) prior to construction. During the construction period, no disturbance beyond the clearing limits shall be permitted. The contractor shall maintain the clearing limits for the duration of the construction. E. The ESC facilities shown on this ESCP shall be constructed prior to or in conjunction with all clearing and grading so as to ensure that the transport of sediment to surface waters, drainage systems, and adjacent properties is minimized. F. The ESC facilities shown on this ESCP are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and modified to account for changing site conditions (e.g., additional sump pumps, relocation of ditches and silt fences, etc.). All changes to the plan shall be noted on the contractors and inspector's approved ESCP set. One updated ESCP set shall be kept on site at all times. G. The ESC facilities shall be inspected daily by the contractor and maintained to ensure continued proper functioning. Written records shall be kept of weekly reviews of the ESC facilities during the wet season (Oct. 1 to May 30) and of monthly reviews during the dry season (June 1 to Sept. 30). H. Any areas of exposed soils, including roadway embankments, that will not be disturbed for two days during the wet season (Oct. 1 to May 30) or seven days during the dry season (May 1 to Sept. 30) shall be immediately stabilized with the approved ESC methods (e.g., seeding, mulching, plastic covering, etc.). I. The ESC facilities on inactive sites shall be inspected and maintained a minimum of once a month or within twenty-four hours before and following a storm event. J. At no time shall more than one foot of sediment be allowed to accumulate within a catch basin. All catch basins and conveyance lines shall be cleaned prior to paving. The cleaning operation shall not flush sediment-laden water into the downstream system. K. Stabilized construction entrances and roads shall be installed at the beginning of construction and maintained for the duration of the project. Additional measures, such as wash pads, may be required to ensure that all paved areas are kept clean for the duration of the project. L. Any permanent flow control facility used as a temporary settling basin shall be modified with the necessary erosion control measures and shall provide adequate storage capacity. M. Where straw mulch for temporary erosion control is required, it shall be applied at a minimum thickness of two to three inches. N. In preparation of the wet season, all disturbed areas shall be reviewed to identify which ones can be seeded in preparation for the winter rains. A sketch map of those areas to be seeded and those areas to remain uncovered shall be submitted to the City by September 15. The City can require seeding of additional areas in order to protect surface waters, adjacent properties, or drainage facilities. Disturbed areas identified for seeding shall be seeded prior to the beginning of the wet season (October 1). O. Blueface inserts shall be installed at curb inlets and drop in inserts at each catch basin. EROSION CONTROL CONSTRUCTION NOTES 1. SEE GENERAL EROSION CONTROL NOTES THIS SHEET. 2.
