Jupiter Inlet Lighthouse Outstanding Natural Area Statement of Work

Shoreline Stabilization

STATEMENT OF WORK

INTRODUCTION

The Bureau of Land Management requires construction services for a shoreline stabilization project in Jupiter, Florida in northern Palm Beach County. The project site lies within the Jupiter Inlet Lighthouse Outstanding Natural Area (ONA), along the Indian River Lagoon and Loxahatchee River. The primary purpose of this undertaking is to stabilize the shoreline, reduce or eliminate erosion, provide for public use where it is compatible with that purpose and enhance aquatic and terrestrial habitats where possible.

BACKGROUND

Congress designated the ONA in 2008 for the protection and enhancement of seven key resources and values present on the site: Historic, Natural, and Cultural resources, and Scientific, Education & Interpretation, Recreation, and Scenic values. Within its designation Congress tasked the BLM with management of the ONA and made the area part of the National Conservation Lands. Congress recognized the area as unique and nationally significant, made more so by the fact that the site is one of only three congressionally designated ONAs in the country and the only complete unit of National Conservation Lands east of the Mississippi.

The ONA’s shoreline along both the Indian River Lagoon and Loxahatchee River – collectively part of the Intracoastal Waterway, is a scenically sensitive, highly visible, and intensively utilized landscape. Attracted by the Caribbean blue water associated with most incoming tides and the rich estuarine ecosystem, visitors, numbering over 25,000/year, use the ONA’s shoreline for boating (including motorized boats, paddle boarding and kayaking), snorkeling and SCUBA, water play and engaging with friends and family in a beach setting. Prevalent use of the area increased since the establishment of the local communities of Jupiter and Tequesta and further increased with trends in outdoor recreation growth, specifically recreational boating. The shoreline is also important for residents and visitors in part due to the iconic Jupiter Lighthouse and the surrounding 35ft sand dune (the highest natural point in Palm Beach County).

These conditions draw the attention to the scenic qualities of the ONA from several homes, businesses (restaurants, clubs, etc.) and traffic routes that offer direct views of the shoreline.

Aside from the scenic and recreational qualities of the shoreline, the shoreline also supports an abundance of biological diversity in the intertidal and transitional zones. Unfortunately, the shoreline is also subject to tidal conditions, storms, wind, surface runoff and incompatible public use that led to a significant loss of material and retreat of the shoreline through erosion. Shoreline erosion is one of the greatest risks to accomplishing the legislative direction for protection, preservation, and enhancement of the values of the ONA. A study completed in partnership with Palm Beach County and Florida Atlantic University documented erosion and shoreline retreat that average over 2ft annually, with the most intensively impacted areas retreating as much as 7ft per year. Based on aerial photographs dating back to the 1940’s, measurements show a loss of over 5 acres of shoreline with a fair market estimated land value in far excess of $60 million.

C2021-084 JILONA SHORELINE STABILIZATION – STATEMENT OF WORK

PROJECT AREA

The project area includes approximately 0.5 miles of shoreline extending from the northern property boundary along the Indian River Lagoon south to Loxahatchee River extending west to the dilapidated former USCG dock. The shoreline includes both the low elevation areas and the embankment of the sand dune surrounding the Jupiter Lighthouse. The legal description is T. 40 S., R. 43 E., Section 31, Lot 17 & Lot

22. Attached is a map of the project area. Elevations range from sea level to approximately 25 feet varying throughout the project area.

OBJECTIVES

The project will construct various shore protection features to provide the following benefits:

1) alleviate erosion along the shoreline and movement of material into the adjacent Intracoastal Waterway,

2) stabilize the shoreline bank to curtail the loss of land and eliminate safety concerns from collapsing sands and falling vegetation,

3) protect the navigability of the Intracoastal Waterway,

4) enhance aquatic and terrestrial habitats and establish native vegetation, as appropriate, to provide for a “living shoreline,”

5) accommodate recreational elements that allow for continued shoreline use for recreational boaters (motorized and nonmotorized) and ONA visitors that allows beach access and supports fishing and snorkeling/SCUBA activities, at appropriate locations,

6) maintain and enhance the scenic integrity of the ONA as viewed from within and from external key observation points.
