EROSION CONTROL SPECIFICATIONS 1) This plan is designed as an attempt to prevent any and all sediment from leaving the construction site by way of erosion. If erosion of sediment from the site is taking place, the contractor sholl take preventative action immediately. The engineer shall be consulted in the event this happens. 2) Temporary seeding shall be applied to any graded area that will remain unaltered for 14 days or longer. 3) Permanent seeding shall be applied immediately to areas that have achieved final and finished grade. 4) Preserve existing vegetation on the site whenever and wherever possible to prevent topsoil erosion. 5) All sediment capturing measures shall be implemented before the disturbance of the construction area they are intended to service. a) provide silt fence around entire project and provide straw bales around existing catch basins on site before earthwork operations begin. b) provide stable construction entrance before earthwork operations begin. c) provide straw bales around new storm, structures immediately after installation. d) provide silt fence around stockpile area as soon as major earthwork operations are complete. 6) Ni erosion control measures shown are to tie properly maintained to continue their effectiveness. 7) If grading occurs during December, January, February dormant seeding procedures shall be used. 8) During dry weather, keep lawns watered with sprinklers or other approved methods. Reseed any areae not germinating or damaged at intervals as may be requirai according to seasonal condition and/or construction activity. Water gross and execute necessary weeding until full stand of gross has been obtained. 9) The implementation and maintenance of the erosion control Is the sole responsibility of the contractor. 10) It shag be the contractor's responsibility to minimize sediimeengtation (from on -sib construction activities) from receiving storm deposit onto adjacerit properU Including etrae4 ee and It shag also be the contractor's hee fro resWthkwall oubmIllty. ity to obtain any approvals required 11) For eeoeond variations - see detail 3 this sheet.
