2. The following water stage, wave, wind, and weather data are provided for inclusion into the subject Plans and Specifications. The following water level datums are provided for information only and are not to be utilized in conjunction with any contract related hydrographic surveying.

a) Water Stages. Water levels in the project area are mainly affected by semi-diurnal tidal fluctuations in the Atlantic Ocean. The project area is also subject to storm surges from hurricanes and tropical storms from June through November. Surges from extratropical storms may affect the area during any time of the year.

Elevations of tidal datums in the vicinity of the project area are provided in the following table.

All datum elevations in this table are in feet, and are referred to mean lower low water (MLLW).

These datums are based on values from a tide station (Station # 9755371) located within the U.S.

Coast Guard compound in San Juan Harbor. This tide station was established by the National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS). Additional information on this and other tide stations in the region is available at this NOAA website :

http://tidesandcurrents.noaa.gov/stationhome.html?id=9755371

Highest Observed Water Level (18 Sep 1989) = 4.34 Feet Mean Higher High Water (MHHW) = 1.57 Feet Mean High Water (MHW) = 1.31 Feet Mean Sea Level (MSL) = 0.77 Feet Mean Tide Level (MTL) (= PR Vertical Datum 2002) = 0.76 Feet Mean Low Water (MLW) = 0.21 Feet Mean Lower Low Water (MLLW) = 0.00 Feet Lowest Observed Water Level (20 Dec 1968) = -1.09 Feet

c) Weather Conditions. 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.

The climate of the area is tropical, and temperatures below freezing do not occur. The project area lies within the ‘tradewind’ zone, resulting in moderate winds from easterly directions the vast majority of the time. The wet season in the project area is from May through October.

Most rainfall events are normally of short duration and amounts are spatially variable. The highest amounts of rainfall are usually associated with passing hurricanes or other tropical disturbances, which can occur from June through November.

It shall be the contractor's responsibility to obtain information concerning weather conditions in the project area.

Geotechnical Data Report

1.1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of borings. The associated boring logs and laboratory data are presented in paragraphs 1.4.6 and 1.4.7, respectively. A character of materials paragraph is included to provide a comprehensive description of the materials utilizing both recent and historical knowledge of the project area. Also included in this section are definitions of terms and boring log notes, which provide additional explanation of the boring logs and drilling techniques.

Items discussed in the character of materials paragraph may not appear explicitly on the boring logs. Based on historic knowledge of the project area, the character of materials paragraph includes items that supplement the data documented by the boring logs. When reviewing the boring logs, use all of the data on the logs, including the materials description, legend, and blow counts. When evaluating the subsurface conditions, use all of the data, including the character of materials paragraph and boring logs.

During the solicitation period, any questions that pertain to the information provided in this section should be addressed to the contract specialist identified in Block 9 of SF1442. After contract award, questions should be addressed to the appointed ACO/COR, which will coordinate with Geotechnical Branch.

1.2 CHARACTER OF MATERIALS

1.2.1 Regional Geology and Local Geology

The study area is located within the shallow marine shelf that surrounds the Commonwealth of Puerto Rico. Sediments of Holocene (0.01 to 0.126 mya) and Pleistocene (0.126 to 2.58 mya) overlie limestone of Tertiary age (2.58 to 65 mya). Periods of fluctuating sea levels occurred during the glacial periods at the close of the Tertiary exposing the limestone allowing for weathering and erosion to occur.

Sediments including silt and clay were deposited on the bottom of San Juan Harbor in the final glacial melt. Shallow lagoons formed in depressions along the coast. Silt and clay were transported from upland areas and deposited by streams.

1.2.2 Materials Encountered

Samples were collected from 14 hand borings and five grab samples for the La Esperanza Borrow Area and Condado Lagoon, respectively. Soft sediment probes were conducted in the Condado Lagoon. Most of these areas consist of sand to silty sand, silt and shell. Debris such as ropes, tires, anchors, wood, roots, and other trash may also be encountered.

San Juan Harbor Maintenance Dredging, 30 Foot Project, and

00 31 32.20 Page-3

1.2.2.1 La Esperanza Borrow Area

Sediment borings less than five feet encountered poorly-graded sand that is composed of fine to medium grained sand-sized quartz and shell. Trace to few silt and gravel-sized shell are also present. Below the sand and shell is silt that is not suitable for mitigation material.

1.2.2.2 Condado Lagoon

Grab samples at selected areas of the bottom sediment indicated primarily silt with areas of well-graded sand to silty sand.

1.3 DEFINITIONS

NOTES:

1. USACE Jacksonville is the custodian for these original files.

2. Soils are field visually classified in accordance with the Unified Soils Classification System.

3. Due to accessibility to the boring locations in shallow-tidal controlled marine zone, the drilling method employed was by pushing a plastic liner 5' long, 2.5" diameter into soil using a 14-lb metal fence post driver.

4. Top of hole elevations were obtained using existing survey monument and tide measurement at time of drilling. Survey monument data:

DESCRIPTION: 14-020-01; NORTHING (ft):

881807.03; EASTING (ft): 760509.76;

Elevation (ft): 4.79 *** Horizontal and vertical datum is NAD 83FT - Adjustment 2011 and PRVD02, respectively***

5. There was 1.7' of water at this location at time of drilling.

6. Boring sealed with available sediment.
