such as sodding , mulching , and seeding shall be implemented and shall be maintained on all erodible ground areas prior to and during construction . Permanent erosion control measures such as sodding and planting of wetland species shall be completed within seven days of any construction activity . Turbidity barriers shall be installed and maintained at all locations where the possibility of transferring suspended solids into wetlands or other surface waters exists due to the permitted activity . Turbidity barriers shall remain in place and shall be maintained in a functional condition at all locations until construction is completed and soils - are stabilized and vegetation has been established . Thereafter , the permittee shall be responsible for the removal of the barriers . The permittee shall correct any erosion or shoaling that causes adverse impacts to the water resources . 12 . The permittee shall hold and save the District harmless from any and all damages , claims , or liabilities which may arise by reason of the construction , alteration , operation , maintenance , removal , abandonment or use of any system authorized by the general permit . 13 . The permittee shall immediately notify the District in writing of any previously submitted information that is later discovered to be inaccurate . 14 . In addition to compliance with the notice provisions of section 40C -400 . 211 , F . A . C . , within 90 days following completion of construction , the permittee will notify by letter the appropriate District office of the date construction activities were completed . 15 . No dredging of access or work channels are authorized by this general permit . 16 . Temporary fill roads shall not be constructed waterward of mean high water or ordinary high . water . 17 . All fill placed in wetlands , other than fill on which a bridge or approach described in paragraph ( 1 ) (a ) is constructed , shall be regraded to the original wetland elevations and these filled wetland areas revegetated with native wetland species endemic to adjoining , undisturbed wetlands , within seven days of completion of construction . Within " clear zones " , as described in Chapter 3 , Roadside Design Manual by American Association of State Highway and Transportation Officials dated October 1988 , hereby incorporated by reference , revegetation shall be with herbaceous species endemic to adjoining , undisturbed wetlands _ These replanted wetland areas shall be maintained , and planted as necessary , to ensure that satisfactory revegetation occurs . For the purposes of this general permit , " satisfactory revegetation " means that the herbaceous wetlands , and forested wetlands within clear zones , that are disturbed by fill shall have achieved not less than 33 percent cover of planted or naturally reestablished herbaceous wetland species within 18 months of completion of construction , and forested wetlands , other than forested wetlands in clear zones , that are disturbed by fill shall achieve a survival rate of not less than 400 wetland trees per acre within 18 months of completion of construction . A maintenance plan must be developed and implemented to ensure the survival of the planted or naturally reestablishing wetland species . Within the revegetated wetland areas , non - native vegetation must be controlled such that it does not constitute more than 10 percent of the areal cover in any stratum at any time for the five year period following the initial planting or restoration of the site . 18 . Hydraulic openings of bridges constructed under paragraph ( 1 ) ( a ) above shall be sufficient to prevent downstream scour , increased downstream water velocities , and increased backwater elevations .
