PROPOSED UNIVERSAL Low ENERGY AQUATIC PLANT SYSTEM (ULEAPSTm) NORTH RELIEF CANAL - 66"' AVENUE AND 53RD STREET AACE Proposal No. P19-1256 Page -3- AACE will take reasonable efforts to reduce damage to property, such as rutting of the ground surface. However, it should also be understood that in the normal course of our work some such disturbance could occur. We have not budgeted to restore the site beyond backfilling our boreholes. If there are any restrictions or special requirements regarding this site or exploration, these should be known prior to commencing the field work. The site is currently not accessible to our truck -mounted drilling equipment due to the presence of former citrus trees. As such, we understand that IRC will conduct a gopher tortoise survey and then clear paths in the vegetation to allow our equipment and crews to access the desired locations on the site. Safety AACE has a commitment to safety of all its employees. As such, and in accordance with our safety culture, we will prepare a "Pre -Task Plan" to identify the potential site safety and job hazards associated with the proposed scope of work. Prior to commencement, and during on-site activities, we will re- evaluate potential job hazards and appropriate safe working procedures. At this time, we anticipate that a United States Occupational Safety and Health Administration (OSHA) Level D work uniform consisting of hard hats, traffic vests, safety glasses, protective gloves, and steel -toed boots will be required by all personnel in the work area. LABORATORY TESTING PROGRAM AACE's project engineer will perform visual classification on the recovered samples and will coordinate a suitable laboratory testing program of select samples. Laboratory testing may include determinations of moisture content, organic content, grain -sizes and percent fines, etc. ENGINEERING ANALYSIS & REPORT AACE will perform engineering analysis of all data obtained to evaluate general subsurface conditions and to develop engineering recommendations relative to site preparation procedures, basin and flow -way excavations, structure/pipe installation, suitability of the excavated materials for use as off-site fill materials, etc. Further, a limited seepage and slope stability analyses will be completed for an anticipated maximum of two cross-sections (to be determined) so as to estimate the seepage loss within the Settling Basins and Polishing Marsh, and also to check for the stability of the perimeter berms and the adjacent NRC canal banks. Our recommendations will be presented in a written report upon conclusion of the study, along with all data developed during the exploration and our laboratory testing. SCHEDULE We will perform the initial site visit(s) within 3 to 5 business days after receiving written authorization to proceed. Weather conditions permitting, we will then mobilize our crew and drilling equipment within an additional 3 to 5 business days and commence drilling. We estimate that we can complete all field work within 7 working days. We further estimate that our laboratory testing, engineering analysis, and report preparation will likely require an additional 10 to 14 business days to complete following the completion of the field and laboratory exploration program.
