Casey Key Geotextile Container Habitat Conservation Plan

Summary: Erickson Consulting Engineers, Inc. (ECE) is responsible for managing all design, permitting, engineering, construction and post-construction monitoring of a sloped geotextile container system and beach fill placement to protect 1,000 feet of upland property and reduce high frequency flood damage to upland development. Recently completing three years of performance and sea turtle monitoring in compliance with the USFWS certified HCP, the project is deemed a successful, sustainable shore protection system for at risk coastal development.

ECE developed a Habitat Conservation Plan (HCP) and secured an Incidental Take Permit (ITP) for potential impacts to sea turtle nesting habitat. The biological goal for the development of the HCP was to maintain suitable sea turtle nesting habitat and to ensure nesting and reproductive success was not reduced as a result of the Project. These biological goals are successfully met when:

    1. Sea turtle nesting success has been maintained or increased from the pre-construction for five concurrent nesting seasons and
    2. Sea turtle reproductive success has been maintained or increased from the pre-construction average for five concurrent nesting seasons.
Key Project Elements:

  • Develop a USFWS “Certified” Habitat Conservation Plan (HCP) Under Section 10 of the ESA
  • Meet with County, State and Federal Agencies
  • Acquire all County, State and Federal Permits
  • Re-vegetation Plans and Design Using Native Plants
  • Environmental Resource Mapping
  • Sea Turtle Monitoring Plan
  • Vegetation Monitoring Plan
  • Sand Cover Monitoring Plan
  • Alternatives Analysis
  • Estimate of Take
  • Development Predator Control Program for Mitigation
  • Post-Construction Performance Monitoring & Assessment
Challenges: ECE arranged a series of meetings with state, federal and local agencies to develop the agreed upon the protection measures for nesting sea turtles. ECE was the first firm install a geotextile container system under the State’s new Rule, 62B-56, FAC and was the first firm to permit such structures in Sarasota County.
