Dredging & Marine Construction
Dredging keeps vital shipping lanes functional to support the economy. It is also essential for creating new land for residential or commercial development. Our marine construction projects involve building seawalls to prevent erosion and constructing, restoring, and upgrading ports.
Coastal Engineering
The successful completion of every project includes an accurate engineering plan that is developed to meet your specific project’s budget and timeline. RPA teams have the experience to guide you through the planning of your project with Site Analysis, Site Planning, and Feasibility Studies.
Dune Restoration & Beach Nourishment
To repair erosion of protective sand dunes along residential shorelines, our team at RPA Services complete full restoration services to rebuild and stabilize natural barriers. Imported and graded clean sand re-establish the dune’s original elevation and contour, reinforced with environmentally responsible coir fiber logs. This biodegradable erosion control strategically provides structural integrity while promoting native vegetation regrowth and safeguards the property from future storm surges and rising tides.
