Pier Replacement and Shoreline Restoration Example

This project removed an L-shaped concrete breakwater and replaced it with a new, fully grated pier on steel piles. A ground base boatlift and two side-mount Jet Ski lifts were added next to the new pier.

Habitat restoration involved adding root wads and small rocks along the shoreline, and moving spawning gravel accumulated by the old breakwater to the nearshore. Additional spawning gravel was brought to the site, resulting in a total of 90 cubic yards added along the shoreline.

Mitigation for the replacement pier included planting emergent vegetation and establishing a 10 foot buffer of native shoreline plants.

Lessons Learned

  • Local Shoreline Master Programs may consider large rocks placed along the shoreline to be a stabilization feature. For this project, the draft design sited 2-5 man rocks along the shore. In the final design, the rock size was reduced to 2-3 man rocks.

  • If possible, take advantage of streamlined permit options offered by the Corps. For example, this project used Nationwide Permits (NWPs) and Regional General Permits (RGPs).

  • Work with agencies and technical experts to evaluate conditions at your site. For example, beach projects need to consider potential migration of gravel away from the site over time due to wave action. For this project, boulders and woody debris were set deep enough to compensate for the beach level changing over time.
