The Coastal Resilience & Adaptation Ecosystem

A Supercharged Innovation Ecosystem

This GO Virginia-funded economic initiative creates a Coastal Resilience and Adaptation Ecosystem in Virginia’s Middle Peninsula region, functioning as a living laboratory and support system for developing technologies designed to protect coastal communities. The project is focused on establishing public-private partnerships between businesses and state universities to design and test resilience solutions under real-world conditions on a network of donated, publicly-owned coastal properties managed by the Middle Peninsula • Chesapeake Bay Public Access Authority.

How Does it Work?

  • Businesses are selected through a challenge competition hosted by RISE Resilience Innovations.
  • Winning projects are then matched to university partners through a competitive process administered by Virginia Sea Grant.
  • The business and university teams work together to find a suitable test site within the Middle Peninsula • Chesapeake Bay Public Access Authority’s portfolio of available properties and begin the process of testing their resilience design technologies.
  • Local companies are subcontracted to provide services to assist with installation and site preparation.
  • Business and university teams have two years of funding and support from the project partners to complete their work.

Advanced Waste Collection and Treatment

This pilot project is more than just an innovation, it’s a beacon of hope for rural coastal homes and businesses. Here’s why:

Overcoming Drainfield Failure: By eliminating the need for a traditional drainfield, this system is a game-changer for areas where they are failing.

Designed for Coastal Challenges: It’s specifically designed to handle the unique challenges of coastal areas – rising sea levels, and more frequent and intense rainfalls.

Safeguarding Homes and Businesses: This system offers a reliable and sustainable  wastewater treatment option, which is crucial for the livelihood and safety of these communities.

THE INNOVATIVE APPROACH

Advanced Waste Collection and Treatment: The system collects wastewater like usual but then treats it in a vertically elevated unit (typically on pilings), ensuring it’s not affected by flooding.

Safe Discharge: Wastewater is treated to a high quality, meeting state standards to discharge away from the property.

Resilient Water Reuse: Alternatively, after treatment, water is stored and reused in a way that’s safe and eco-friendly (irrigation, flushing toilets, etc.), a big plus for areas where water resources can be strained.

Developing Production Methods of Native Wetland Plants

Project Objectives

  • Compile protocols for field and lab cultivation methodologies of critical native wetland plant species. Initially, work will focus on Spartina alterniflora (Saltmarsh Cordgrass).
  • Act as consultants to Knott Alone – Hold Fast, Inc. in their endeavors to develop their plant production capabilities.
  • Refine and validate greenhouse/field culture methodologies for critical native wetland plants.
  • Determine the feasibility of sustainable harvesting of native grasses from natural wetland systems for plant production purposes.
  • Develop in vitro culture methodologies for Spartina alterniflora.
  • Explore the possibility of mutagenesis (the production of genetic mutations) as an avenue for the creation of new Spartina alterniflora varieties for production.

Anticipated Outcomes

  • As a result of two growing seasons propagating plants in lab, greenhouse, and field a substantial number of plants will be produced. These plants will be made available for restoration projects along the Elizabeth River or used for additional tests in the Norfolk State University greenhouse.
  • Collected seed will produce a stockpile which can be used by Knott Alone – Hold Fast, Inc. for production or NSU for expanded culture tests. It is unlikely these will be made widely available due to novel storage requirements to ensure viability.

Best Practices for Planting Desired Coastal Vegetation Species

Research Tasks

  • Compare planting strategies (standard spacing of transplants vs. high-density spacing of transplants vs. donor-marsh transplants) in terms of plant survival and marsh expansion over at least one growing season.
  • Examine sustainability of marsh transplant removal intensities in donor marsh locations to determine best practices for obtaining marsh transplant materials while minimizing damages to existing marsh.
  • Monitoring of plant survival, vegetation density, and species richness both pre- and post-construction, and the following growing season.

Anticipated Outcomes

The anticipated outcomes from these tasks include data on plant survival, lateral expansion (area of vegetated cover), plant performance (stem density, height, overall plant vigor), and below-ground biomass production that can be used to assess the impact of planting strategy on marsh revegetation, turbidity and wave attenuation. Transplant donor marsh locations will be monitored for recovery of above- and below-ground parameters (below-ground biomass, stem density, sediment physiochemistry, elevation) to determine the suitability for the practice of marsh transplanting and the speed of reference marsh recovery.

Dredge Material Collection and Reuse

Biogenic Solutions Consulting - Use of Onsite Materials

Both DredgeSox and GeoTube geotextile shoreline stabilization structures installed by Biogenic Solutions, Ready Reef, and Golden Oyster utilize shallow sediments and sands that were dredged onsite from the Whittaker Creek canal. 

Natrx - Repurposing Dredge Material

  • Successful Research: Natrx has tested and validated the use of dredged sediments as a partial cement replacement in its Exoform™ shoreline stabilization structures (shown above) through a process called calcination.
  • Scale of Operations: The amount of dredged clays in the Middle Peninsula far exceed the demand for producing Exoform™ structures — 100,000 cubic yards of dredged sediments would create enough armoring for 1,000 miles of shoreline.
  • Economic Impact: The beneficial use of dredged sediments could have enormous primary economic benefits in rural areas including reduced sediment disposal costs, job creation, and lower material costs for construction and resilience activities.

DredgeSox

  • DredgeSOX Erosion Control is designed with a double layer of knitted polyethylene mesh that is filled by dredging shallow sediment into the containment unit.
  • When sediment is fine, polymer flocculants are used to bind the sediment which enables it to be retained within the DredgeSOX.

EnviroLok Bags

  • Envirolok is a fully-engineered geobag system designed to permanently stabilize slopes, waterways, and shorelines.
  • Envirolok combines the engineered strength of soil with the principles of plant ecology to deliver a sustainable, vegetative solution that will stand the test of time.
  • Envirolok’s resilience grows as the roots create a binding matrix through the bags and into the native soils behind.

GeoTubes

  • GeoTubes are engineered woven geotextile tubes for coastal erosion control, shoreline protection, and stabilization which are typically filled with onsite sands or other material pumped into the core for sustainable, soft armor protection.
  • The geotextile tube material is inert to biological degradation and resistant to naturally encountered chemicals, alkalis, and acids.
  • Hybrid GeoTubes can be planted with native grasses when installed on or adjacent to land.

Natrx Adaptive Infrastructure

Transforming Dredged Material into Sustainable Solutions with Natrx

Natrx is paving the way for a more sustainable future by turning dredged material waste into a key component for eco-friendly construction. The climate technology company has developed an innovative technology that uses dredged material as a partial replacement for cement in concrete. This process involves heating the dredged material to produce calcined clay, which can substitute up to 70% of the cement in concrete production. This groundbreaking approach offers numerous benefits:

  • Environmental Impact: Instead of sending dredged materials to landfills, Natrx repurposes them, reducing waste and making it easier for dredging projects to gain approval. The substitution of traditional cement with calcined clay significantly reduces greenhouse gas emissions, making concrete production more environmentally friendly.
  • Cost Savings: By converting waste into a valuable product, Natrx’s new approach has the potential to lower disposal costs for dredging projects by about 50%, saving $2 million to $3.8 million annually. Over 20 years, this adds up to $20 million to $76 million in savings.
