Sea and Shoreline

What Sea and Shoreline does

Sea & Shoreline, LLC is a Florida-based, privately held aquatic restoration firm founded in 2014 by Jim Anderson, a turf farmer and nursery operator who developed patented subaquatic restoration technologies after encountering propeller-scarring damage at a local fishing area. The company specializes in restoring freshwater and saltwater habitats, with a core competency in seagrass and submerged aquatic vegetation (SAV) restoration that the company states is unmatched globally — it claims to have planted more seagrass than any other firm and operates the world's largest aquaculture nursery in Ruskin, Florida, with a joint nursery at Hubbs SeaWorld in Sebastian and a new dedicated nursery supporting its Indian River Lagoon program. Service offerings span the full restoration lifecycle, including dredging, propeller scar repair, oyster reef creation, living shorelines, coral reef restoration, breakwaters, vegetated retaining walls (via licensed Envirolok technology), mitigation banking, and surveyor-grade DGPS mapping, all underwritten by a portfolio of granted patents covering underwater liquid fertilization, mechanized planting, sod transplantation, sediment tubes, and GrowSAV herbivory exclusion devices.

The business model is project-based and B2B/B2G, with sales-led acquisition through direct engagement with government agencies — Florida Fish and Wildlife Conservation Commission, Florida Department of Environmental Protection, US Army Corps of Engineers, water management districts, and state park systems — supplemented by partnerships with conservation nonprofits such as the Fish & Wildlife Foundation of Florida, Coastal Conservation Association Florida, and Florida Wildlife Corridor Foundation. Pricing is quote-driven and non-public, with multi-year contract cadence and documented per-project values in the seven-figure range (e.g., $9.4M Indian River Lagoon award, $1.8M Rainbow River award); the company also generates revenue through mitigation banking credits and surveying/permitting services. Customer concentration sits entirely within the public-sector and nonprofit environmental vertical, spanning Florida, North Carolina, and South Carolina, and the leadership team combines marine biology, marine geology, aquaculture, and certified general contractor credentials to execute end-to-end scientifically validated restoration with documented survivability rates above 95% on certain projects.

Products and services

• Submerged Aquatic Vegetation / Seagrass Restoration Core end-to-end seagrass and submerged aquatic vegetation restoration service that uses seagrass as the basis for crystal clear water. The process includes dredging to provide clean substrate, seagrass planting, protecting shoots with GrowSAV devices, and ongoing maintenance to ensure healthy growth. Targeted at government agencies, municipalities, and conservation organizations seeking to restore degraded aquatic ecosystems.
• Dredging Physical removal of muck and excess nutrients from water bodies, addressing accumulated organic debris including leaves, fish waste, decaying plants, dead algae, and runoff from agriculture, fertilizers, and septic systems. Used to prepare clean substrate for seagrass and SAV restoration.
• Propeller Scar Registration (Sediment Tubes) Repairs boat propeller scars by installing sediment tubes that fill the scars, prevent further erosion, and serve as a foundation for seagrass growth. The tubes deteriorate over time as seagrass recolonizes the scars. Targeted at water bodies with heavy boating traffic where propeller damage has degraded seagrass beds.
• Oyster Reefs Creation of oyster reef habitats that filter particles from the water column (each adult oyster filters up to 50 gallons of water per day) and provide natural protection from storms and waves. Reefs also support marine biodiversity. Targeted at improving water quality and shoreline resilience in bays, lagoons, and estuaries.
• Wetland Plants Supply and installation of native aquatic plants for wetland and shoreline projects, including species such as Seashore Paspalum for ground-cover in high pH, hydric, and saline soil conditions. The company also offers contract growing for less common native species. Supports clients seeking natural shoreline and wetland stabilization with regionally appropriate plant palettes.
• Living Shorelines Erosion control solutions that combine submerged aquatic vegetation, wetland plants, stone, sand fill, oyster reefs, and other materials to provide long-term shoreline protection while restoring habitat. Targeted at coastal property owners, municipalities, and agencies seeking alternatives to bulkheads and seawalls.
• Coral Reefs Coral reef restoration delivered through grow, transplant, and restoration activities working with top coral researchers. Protects coastlines, provides marine habitat and food, and supports biodiversity. Targeted at reef-bearing coastal waters including the Florida Keys (e.g., John Pennekamp Coral Reef State Park).
• Mitigation Banks Creation and protection of natural resources through habitat credits that offset environmental impacts of development projects. Services include site evaluation, permitting, and mitigation. Targeted at developers and regulated entities that need to satisfy environmental mitigation requirements for coastal and aquatic impacts.
• Breakwaters Wave energy mitigation structures that reduce wave intensity while preserving natural wave paths and promoting shoreline stability by allowing suspended sediments to settle and form protective sandbars. Targeted at shorelines exposed to damaging wave energy that require erosion control and habitat preservation.
• Vegetated Retaining Walls Installation of vegetated retaining walls using the patented Envirolok System, which employs geometrically designed soil bags that lock together with deep-rooted native plants to provide long-term erosion control and slope stabilization. Licensed from Envirolok for vegetated retaining wall installations. Targeted at sites requiring slope stabilization combined with habitat and aesthetic outcomes.
• Surveying and Mapping Surveyor-grade DGPS mapping for accurate depiction of natural resources. Includes bathymetry surveys, flora and fauna community identification, modified Braun-Blanquet method, percent cover estimation, short shoot counts, wetland delineations, and UMAM calculations for permitting. Targeted at restoration projects requiring scientifically defensible baseline data and permitting documentation.
• Manatee Seagrass Feeding Solution An innovative intervention service developed in response to the manatee mortality event, providing supplemental seagrass feeding for starving Florida manatees while broader seagrass restoration efforts progress. Targeted at state wildlife agencies (FWC) and conservation partners responding to manatee starvation events caused by seagrass habitat loss.

Quantifiable outcome

• Seagrass can sequester as much as 50 times the amount of carbon in its soil per hectare as a tropical forest, and for a longer period (hundreds or thousands of years)
• +4 more outcomes
