How Restoration Can Benefit Habitat

• Restore marine riparian

• Restore native beach sediment

• Large woody debris recruitment

• Enhance forage fish spawning

habitat

• Enhance habitat adjacent to

eelgrass beds

• Provides habitat and food for

salmon

Project Goals

• Improve habitat for nearshore species

• Create vegetation buffer and connectivity of uplands to beach

and nearshore

• Restore natural beach processes by removing derelict shore

armor

Page 18: Hidden Beach Restoration

Restoration Concepts

• Remove failed armor: pilings, horizontal wood, boulders, concrete

bags, and other miscellaneous debris

• Potentially remove concrete pad, move and/or shorten parking area

• Plant native vegetation

• Create path(s) to beach from parking lot through vegetation buffer

Page 19: Hidden Beach Restoration

Restoration Concepts-Example

• Driftwood Beach,

Blakely Is.

• Pre-project 1998

• Removed fill and

debris

• Nourished beach,

restored beach

topography

• Planted riparian

Page 20: Hidden Beach Restoration

Restoration Concepts

• 1999 – 2016

• Very little vertical

change

• Community

satisfaction high

Coastal Engineering Geology Assessment

Coastal Geologic Services provided an initial feasibility assessment of shore armor removal at Hidden

Beach on June 29, 2018. Report is available on project website.

Key findings are as follows:

• The majority of the erosion of fill placed in this reach appears to have already occurred, as most of the

old pile wall was gone and the placed boulders were scattered in such a manner that they no longer

functioned as a revetment or other coherent shore protection structure

• The Whidbey Telecom access could potentially be threatened with full armor removal. Additional

investigation of future erosion projections and ownership/easements will be required.

• Hidden Beach Road is the most landward improvement and would not appear to be threatened by

erosion, even with full removal.

• The waterward edge of the parking lot may be threatened with erosion over the medium to long term

with full armor removal. However, the parking lot is quite large in the cross-shore direction and likely

could be reduced in size without losing much function.

Known Concerns and

Design Considerations

• Adjacent Hidden Beach

community properties

• Gravel road and Whidbey

Telecom fiber optic cable

• Road and parking lot area

• Public use and access to

beach
