Engineering for the Coast
Coastal sites in Texas, North Carolina and Florida face three linked risks: hurricane winds, flooding and storm surge, and soils that can shift, erode or scour.
If a design handles one of these and ignores the others, the building is still exposed.
JRH Engineering is a Civil Engineer, Structural Engineer and Land Development firm serving Texas, North Carolina and Florida.
JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
Wind
Wind loads follow ASCE 7 and the locally adopted building code, using the site's mapped design wind speed
A continuous load path from roof to foundation, with hurricane connectors at rafters, studs and anchors
In Texas's designated catastrophe area, TDI windstorm rules apply; JRH supports WPI-8 certification in Brazoria and Galveston counties
Flood
Finished floors at or above the base flood elevation plus any local freeboard
In FEMA Zone V, open, deep foundations on driven piles with the lowest horizontal member at or above the design flood elevation
ASCE 24 sets flood-resistant design and construction standards
Drainage that still works when tides and groundwater are high
Foundations and Soils
Texas: expansive clays and soft coastal soils often call for drilled piers or piles
North Carolina: sandy barrier soils and erosion affect pile depth and scour design
Florida: sandy soils, high groundwater and, in some areas, sinkhole risk
Geotechnical investigations are performed by others and drive the foundation design
Durability
Hot-dip galvanized or stainless connectors near salt air
Concrete cover and mix design suited to chloride exposure
What JRH Does Not Design
Shoreline structures, living shorelines and dune work (by coastal specialists)
Windows, doors and other impact-rated products (by manufacturers)
