AE6412.The horizontal coordinates were established by GPS observations AE6412.and adjusted by the National Geodetic Survey in June 2012.

AE6412

AE6412.NAD 83(2011) refers to NAD 83 coordinates where the reference AE6412.frame has been affixed to the stable North American tectonic plate. See AE6412.NA2011 for more information.

AE6412

AE6412.The horizontal coordinates are valid at the epoch date displayed above AE6412.which is a decimal equivalence of Year/Month/Day.

AE6412

AE6412.The orthometric height was determined by differential leveling and AE6412.adjusted by the NATIONAL GEODETIC SURVEY AE6412.in January 2002.

AE6412.The X, Y, and Z were computed from the position and the ellipsoidal ht.

AE6412

AE6412.The Laplace correction was computed from DEFLEC12A derived deflections.

AE6412

AE6412.The ellipsoidal height was determined by GPS observations AE6412.and is referenced to NAD 83.

AE6412

AE6412.The dynamic height is computed by dividing the NAVD 88 AE6412.geopotential number by the normal gravity value computed on the AE6412.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45 AE6412.degrees latitude (g = 980.6199 gals.).

AF6695'RECOVERED IN GOOD CONDITION.

1. The below stated water fluctuations are for informational purposes only and are not to be utilized in conjunction with any contract-related hydrographic surveying purposes as noted on the control drawing(s) of the contract plans. All elevations in this Section 00 33 50 are in feet, National Geodetic Vertical Datum of 1929 (feet, NGVD).

2. The Herbert Hoover Dike (HHD) Rehabilitation, Culvert

Replacement, Culvert IP-3 Project is located in Levee 48 (L-48) along the Canal 40 (C-40) which is on the western end of Lake Okeechobee in Reach 8 of HHD. IP-3 is located in the Levee 59 (L-59) Borrow Canal where it intercepts C- 40 at the northwestern portion of the L-48 IP-3 is approximately 400 feet downstream from Structure 72 (S-72) which is approximately 3.5 miles upstream (north) of Lake Okeechobee. Also, the IP-3 site is approximately 200 feet east of where the Levee 60 (L-60) Borrow Canal intercepts the C-40.

3. IP-3 is a double-barrel, corrugated metal pipe culvert with flap gates at the outlet and flashboards at the inlet. The purpose of this structure is to provide continuity for the L-59 Borrow Canal through the L-48

4. Water levels at the project locations are mainly affected by rainfall, evaporation, local runoff, water supply deliveries through C-40, groundwater levels (e.g., seepage from the C-40 Canal and the operation of Lake Okeechobee. Lake Okeechobee is managed by the Jacksonville District, U.S. Army Corps of Engineers (Corps) in accordance with the 2008 Lake Okeechobee Regulation Schedule (2008 LORS), which is shown in Figures 1 through 4. The lake’s optimum range of elevations is between

12.5 and 15.5 feet, NGVD on a seasonally varying basis. This optimum elevation range may be exceeded due to rainfall events over the lake’s watershed, and/or wind effects on the lake.

5. Historical average daily lake elevations from January 1932 through September 22, 2015 are provided graphically in Figure

5. The maximum average daily lake elevation of 18.77 feet, NGVD occurred on November 3, 1947. These average daily water elevations may be exceeded due to rainfall events over the lake’s watershed, and/or wind effects on the lake. Exceedance curves for the Lake Okeechobee average daily water elevations

SECTION 00 33 50 WEATHER AND WATER STAGE DATA

SECTION 00 33 50 Page 1 for the above-referenced period of record are contained in Figure 6. The graph contains the 10, 25, 50, 75 and 90 percent exceedance values through the calendar year. For example, for a given day in the calendar year, the “10% Exceedance” curve shows the water elevation at which 10 percent of the values on that day were greater for the period of record. These graphs may also be used as a rough indicator of the probable seasonal variations in elevations.

6. Historical average daily C-40 elevations as measured at S-72 tailwater are provided graphically in Figure 7 for the period of record from April 30, 2003 through October 13, 2015. A maximum elevation of 18.09 feet, NGVD occurred October 10, 2004.

7. Historical flows for S-72 are provided graphically in Figure

8 for the period from March 14, 2011 through October 13, 2015.

A maximum flow of 3,404 cfs occurred on August 29, 2012.

8. Historical average daily L-59 Borrow Canal elevations as measured upstream from IP-3 for the period of record from May 9, 2003 through October 13, 2015 are provided graphically in Figure 9. A maximum elevation of 20.33 feet, NGVD occurred on November 16, 2006.

9. All hydrometeorological data in this Section 00 33 50 are provisional and subject to revision. The contractor should understand that historical water elevations and discharges are not necessarily indicative of future water elevations and discharges. The contractor should be able to obtain hydrometeorological data from the Corps’ Jacksonville District Water Management Section's website, which can be found at:

http://www.saj.usace.army.mil/Missions/CivilWorks/WaterManagem ent.aspx and South Florida Water Management District’s website which can be found at: http://www.sfwmd.gov.

10. The contractor should not expect that work can be done under

“no flow,” “low flow” or dry conditions.

11. It shall be the contractor's responsibility to obtain information concerning rain and wind. Reference is made to the National Oceanic and Atmospheric Administration (NOAA)

SECTION 00 33 50 Page 2 http://www.saj.usace.army.mil/Missions/CivilWorks/WaterManagement.aspx http://www.saj.usace.army.mil/Missions/CivilWorks/WaterManagement.aspx http://www.sfwmd.gov/portal/page/portal/sfwmdmain/home%20page http://www.sfwmd.gov/portal/page/portal/sfwmdmain/home%20page publication entitled Local Climatological Data – Monthly Summary, which contains climatological and meteorological observations and data, including wind, rain, and temperature data for the project area. Subscription price and ordering information is available from the National Climatic Data Center, Federal Plaza, 151 Patton Avenue, Asheville, North Carolina 28801-5001. NOAA also has an internet information page at: http://www.ncdc.noaa.gov/.

12. The climate in the project area is subtropical and humid.

The project area is subject to tropical storms and hurricanes from June through November, and to windy and/or rainy weather during any time of the year. Temperatures below freezing are rare. May is generally a transitional month in which storms that typically occur in June through September may begin. The typical rainfall from October through May is associated with mid-latitude systems (fronts and low-pressure systems) and is distributed in a spatially uniform pattern. Typical June through September rainfall is closely associated with convective activity. These rainfall events are normally of short duration and amounts are quite variable spatially.

Occasionally, daily rainfall during the typical rainfalls of October through May could be quite heavy as mid-latitude systems penetrate into Florida. Weather forecasts as well as actual rainfall information from the National Weather Service Miami-South Florida forecast office can be accessed at:

http://www.srh.noaa.gov/mfl/.

13. The following data are provided:

The average number of work days in each calendar month with precipitation greater than or equal to 0.50 inches is provided for the project areas in the below Table. This information is based on data obtained from Station Okeechobee, located at latitude 27.1508 N and longitude -80.8653 W. The data was obtained from Climatography of the United States No. 20 Monthly Station Climate Summaries for Florida, published by the National Climatic Data Center, NOAA, for the period of record 1981-2010.

The values in this table have been rounded to the nearest whole number.
