Jupiter Inlet, Channel and Inlet Dredge Survey and South Beachside Fill - March 2011

Land & Sea also recently completed a project in Jupiter for the Jupiter Inlet District.   The project consisted of dredging the inlet channel and sand trap area and placing fill on the beach south of the inlet. This was a two phase project with Phase I completed in early 2010 and Phase II completed in March 2011. Land & Sea Surveying provided stake-out for the beach fill area as well as hydrographic surveys of the dredge areas. Surveys were completed for pre-construction conditions, interim and post-construction conditions with cross-sections and material quantities.

Gulf of Mexico - HYPACK Navigation and Environmental Sampling - Sept. 2010 Ongoing Project

In September 2010, Land & Sea Surveying began working on a project in the Gulf of Mexico which involved using HYPACK to navigate 165 to 210 foot vessels and collecting environmental samples, operating ROV with HD video and soil sampling equipment, testing with CTD Sensor, and mapping with multi-beam hydrographic system.  This project is ongoing.

St. Lucie Inlet, Martin County - USACE Project ICWW/OWW Maintenance Dredging

From November 2009 to March 2010, Land & Sea Surveying worked on the USACE project  ICWW/OWW Maintenance Dredging, Cross-Roads, Martin County. We provided staking of the proposed dredge area as well as hydrographic surveys for pre-constuction conditions, interim surveys for completed sections, and as-built surveys with quantity calculations at each stage. Surveys were also performed of the spoil area.

Naples, FL - USACE Dredge of Martin's Pass Pre/Interim/Post Construction Surveys - April 2011

In April 2010, Land & Sea Surveying began a USACE project in Naples, Florida. This project consisted of dredging 2,100 linear feet of the channel at Gordon Pass. Land & Sea Surveying provided pre-construction, interim and post-construction surveys. Deliverables were provided meeting the USACE standards and included plan view, cross-sections and quantities.

 

St. Augustine, FL - Salt Run Inlet Hydrographic Survey - 2009

Land & Sea worked with Taylor Engineering to provide pre-design Hydrographic Surveys of the Salt Run area at St. Augustine Inlet. We then worked with the contractor to quantify the amount of material removed from the dredge area. This project required an innovative approach to ensure that the contractor met the specifications of the design. The material in the dredge area was so soft that as soon as the dredge pulled material out, it sloughed back in from the sides. The hydrographic survey using acoustics did not show any significant change, even when performed immediately after dredging. Land & Sea Surveying negotiated on behalf of the dredger and the St. Augustine Port District. The dredge contractor agreed to document the number of barge loads removed using Hypack targets and date/time stamped photographs. Land & Sea Surveying calculated the quantity of material removed by number of barge loads and volume of the barge. We additionally performed acoustic surveys of the area verifying that dredging was being performed in the designated dredge area and showing quantity differences from the barge count to the acoustic measurement.

Sebastian Inlet, FL - BiAnnual Topographic/Hydrographic Survey - 2004 to Present

Twice each year, Land & Sea Surveying performs a topographic/hydrographic survey at the Sebastian Inlet. The survey area covers the channel from the Intracoastal Waterway to an area approximately 2,000 feet by 4,000 feet, encompassing the sand trap and shoals in the Indian River, through the inlet, then approximately six miles to the north and south. On the north side of the inlet and the south 13,000 feet of the south side (R-17 to R-30), beach profiles from the top of dune out to a depth of 40 feet are done every 1,000 feet. For the first 17,000 feet (R-1 to R-17) on the south side of the inlet the survey is performed in a manner to provide 100% coverage utilizing upland GPS surveying methods, near-shore single-beam hydrographic collection and multi-beam survey of the offshore area.

The survey is used by the Inlet District in developing the Inlet Management Plan, which is updated annually to address issues such as sand bypassing, changes to the shoreface, coastal erosion, navigation and environmental issues. Inlet management planning is an ongoing project. The goal of this project is to assemble existing data sets collected by the Sebastian Inlet District and its consultants into an interactive GIS and remote sensing database that can be used to examine long-term trends and shorter-term variability of the beach, shoreface and overall sand budget of Sebastian Inlet. The database is used to assemble shoreline change data, volumetric data and morphologic data that is used in calculations and predictive models to quantify the littoral sand budget and predict the potential for impacts during severe storms. The database will also drive models to simulate the potential for morphologic changes in the barrier island shoreface and tidal inlet shoals. The final product of the project is a comprehensive 'State of the Inlet' report that is updated on an annual basis to quantify year to year conditions and thus provide a flexible and dynamic management tool. Land & Sea Surveying has been working with the Sebastian Inlet District since 2004.

 

Titusville, FL - Submarine Cable Location for Qwest Communication

Land & Sea Surveying was called upon to locate a subaqueous cable in the Indian River at the Max Brewer bridge. Reconstruction of the fishing pier destroyed in past hurricanes had begun and the contractor almost hit the cable upon sinking the first piling. The owner of the utility requested that we mark the location of the utility. We were called on a Thursday and completed the location and marking by Sunday. The owner of the utility was provided with a surveying showing the underwater mapping in the area of the cable and the exact location of the cable with an aerial background. The survey drawing also included a chart with coordinates of the cable location.

 

Ft. Pierce , FL - City Marina Project and Moores Creek  

In 2004, Land & Sea Surveying began working with the City of Ft. Pierce on several projects for their City Marina. The project was originally for dredging of a north entrance channel to the marina, however, due to the storms that caused significant damage to the area at the scheduled start of the project, Land & Sea Surveying also assisted with locating obstacles in front of the marina. Following the channel construction project, we continue to provide surveys for the maintenance of the marina basin, Moores Creek and the entrance channel with the most recent survey completed in May 2010.

 

Various Locations, Atlantic Coast - Surfbreak Engineering, Inc Various Projects  

Land & Sea Surveying has worked with Surfbreak Engineering, Inc. and Dr. William Dally over the years on several coastal engineering projects. We assisted with wave meter installation and retrieval projects along the Atlantic coast from Lake Worth to Jacksonville, setting the vertical and horizontal position of the meter using RTK GPS in addition to providing divers and vessels. Land & Sea also worked with Dr. Dally on current studies in the St. Johns River in Jacksonville and Salt Run at the St. Augustine inlet. We assisted in collection of current data using Acoustic Doppler Current Profilers (ADCP) and current meters. Data collected was utilized in the design of templates for dredging projects.

Beach Profiles for Beach Renourishment Projects and Post-hurricane conditions

Beach Renourishment projects have included performing profiles for pre-dredge and post-dredge conditions in addition to hydrographic surveying of the borrow area. 

Post-hurricane condition surveys consisted of performing beach profiles with continuation by hydrographic surveying to an established depth to determine the migration of sand. The surveys were utilized to obtain funding from the state and federal government agencies to reconstruct the beaches.
