Engineering

Innovative environmental engineering services and infrastructure solutions.

By providing communities with reliable access to clean resources and protection from dangerous environmental hazards, carefully-designed infrastructure is critical to securing the health and prosperity of our society. Behind every life-saving infrastructure solution is a team of specialists providing comprehensive engineering services.

JESCO has helped federal, state, municipal and private clients overcome daunting challenges presented by issues like population growth and aging infrastructure. With 30 years of experience to our name, the JESCO team stops at nothing to provide efficient and effective engineering services for our clients.

Environmental Engineering and Flood Protection

JESCO’s primary environmental engineering services include technical support, field research, and demonstration services concerning soft-armoring and erosion control of levee embankments. We ensure the success of these projects through a blend of agronomic solutions that utilize turfgrass establishment, soil management, weed removal, and pest control solutions.

JESCO has had the opportunity to work alongside the New Orleans District U.S. Army Corps of Engineers (CEMVN) to protect our neighboring community from dangerous flooding and other environmental risks. These projects include the Hurricane and Storm Damage Risk Reduction System (HSDRRS), the Mississippi River & Tributaries (MR&T) project, and the installation and management of over 300 miles of levee embankments.

Field Service Management

The JESCO headquarters are located in the coastal region of Southern Louisiana, so we are well-aware of the importance of coastal preservation and the protection that healthy coasts provide for their surrounding environment. Because of this, we are committed fully to working with local and national partners to help protect America’s wetlands.

As part of this effort, JESCO provides the following coastal restoration and preservation services:

  • Planning
  • Design
  • Installation
  • Evaluation
  • Operations
  • Maintenance
  • Monitoring
  • Coastal Grasses Nursery

Additionally, we have partnered with Louisiana State University to support and provide exclusive coastal preservation grasses that provide superior benefits to other common solutions.

Coastal Preservation Grasses

Dunes and wetlands serve as natural lines of defense against storm surges and coastal flooding. But, without a sufficient amount of coastal grasses to guard against coastal erosion, these powerful barricades begin to fall apart and the risk of flooding and further erosion increases.

That’s why JESCO has partnered with Louisiana State University (LSU) to maintain stocks of unique coastal grasses needed to preserve the coasts of Louisiana. LSU researchers noticed that smooth cordgrass and sea oat grasses were extensively used in coastal preservation, but were concerned with a lack of genetic variation between these two varieties (making our coasts particularly susceptible to plant disease and pest infestations).

To solve this issue, LSU developed six new smooth cordgrass varieties and three new sea oat varieties to increase biodiversity and improve the adaptability of restoration plantings. These new coastal grass varieties also came with a number of advantageous adaptations compared to the original varieties:

  • Superior vigor
  • Taller height
  • Larger leaves
  • Greater stem density
  • Increased tiller production
  • Increased tiller spread
  • Improved transplant recovery
  • Improved seed production
  • Better germination rates
  • Increased erosion resistance

JESCO holds an exclusive contract with LSU to maintain breeder stocks of these new smooth cordgrass and sea oat varieties for the explicit purpose of supporting projects that aim to protect, preserve and restore Louisiana coastlands.

Due to their popularity and commercial viability, JESCO’s smooth cordgrass varieties are the most common preservation grass we supply. These smooth cordgrass varieties are only supplied to be used as foundation material for coastal restoration projects. Our sea oat grass varieties are also available to be used for similar projects, but are primarily used for seed harvesting (along with other exclusive “advanced breeder lines”).
