Description
Eagle Harbor (MA-5) comprises 46,054 ft of shoreline that encompasses all of Rockaway Beach and Eagle Harbor, including all of Bill Point and part of Wing Point (Table A-1, Figure 2). This diverse MA comprises 35 reaches broken into the following categories: marsh/lagoon (10), spit/backshore (8), low bank (8), and high bluff (4) (Figure B-39). MA-5 is defined by three major drift cells (Figure 3). Two of them begin at the outer margins of Eagle Harbor (Wing Point and Bill Point) and move westward, terminating in the middle of Eagle Harbor, an area that lacks appreciable alongshore drift. The third drift cell begins at a divergence zone located just to the north of Blakely Harbor and moves north along Rockaway beach to Bill Point. Relative to wave exposure, all shorelines along the eastern shore, facing Puget Sound, are considered “semi-protected,” whereas the inner portion of Eagle Harbor is considered “very protected”(Figure B-40)). Eagle Harbor receives upland flows from six watersheds with moderate-to-high levels of land use: WRIA 15.0330 (TIA 3%), WRIA 15.0329 (TIA 4%), Sportsman’s Club Pond Creek (WRIA 15.0325; TIA 10%), WRIA unnumbered 48 (TIA 60%), Ravine Creek (WRIA 15.0324; TIA 40%), and WRIA unnumbered 22 (TIA 18%).
Overhanging riparian vegetation covers approximately 23% of the MA-5 shoreline, among the lowest values for this characteristic among MAs on Bainbridge Island (Table A-1, Figure B-45). Within the 200-ft riparian zone, naturally vegetated surfaces (coniferous and deciduous trees, shrubs, and wetlands) compose only 36% of land cover, whereas impervious surfaces (e.g., roads, roofs) represent 45% of land cover (Figure B-44). Eagle Harbor was the only MA on Bainbridge Island where the %TIA exceeded the percentage of natural vegetation in the marine riparian zone.
Eagle Harbor (MA-5) is the commercial and industrial heart of Bainbridge Island, and includes the City’s downtown, a Washington State Ferry terminal and repair facility, multiple commercial marinas, and a Superfund site at Bill Point, throughout portions of the outer harbor, and at the mouth of the Ravine Creek. There is also the City’s Waterfront Park in Eagle Harbor that provides shoreline access, boat launch facilities, and visitor moorage (Figure B-43). The remainder of MA-5 shoreline has typical single-family residential development, with some shoreline backed by public roads. Almost 53% of the shoreline is modified by armoring and 30% of the shoreline has armoring that encroaches into the intertidal zone, high values when compared with all other MAs on Bainbridge Island (Table A-1, Figure B-41).
A total of 506 point modifications were recorded along MA-5 shorelines, at an average of 11 modifications per 1000 ft (Table A-1, Figure B-42). Most of these modifications are associated with boat facilities, including pilings (89), moored boats (78), mooring buoys (66), and docks (60). At least 17 marinas, defined as a dock with more than five mooring slips, were present along the shoreline of MA-5. A total of 38 outfalls were also recorded along MA-5 shorelines.
Limiting Factors
The average normalized CF score within MA-5 was -0.56, the lowest (worst) MA score on Bainbridge Island (Table A-2, Figure B-10, Figure B-13). Eagle Harbor (MA-5) had among the lowest (poorest) scores of all MAs in four of the nine metrics: depth slope, pollution, hydrology, and physical disturbance; no metrics placed among the high (good) scores (Table A-3, Figure B-16). Depth and slope scores were low (poor), in part, because dredging activity occurred in at least seven reaches within the MA. As well, depth and slope scores reflected the relatively high rate of armoring encroachment (30%) along Eagle Harbor shorelines. Pollution scores were low (poor) in MA-5 because of recreational shellfish closures/warnings throughout all reaches in and around Eagle Harbor from contaminated runoff, marinas, the Eagle Harbor/Wyckoff Superfund Site, and the sewage treatment plant outfall at Wing Point. High %TIA in the marine riparian zone (45%), high outfall densities, and impaired tidal hydrology due to the high rate of armoring encroachment influenced the low (poor) hydrology metric score. Finally, physical disturbance scores were low (poor) primarily because of the “urban” setting (ferry activity) of some reaches, low forested cover in the marine riparian zone (36%), and relatively high number of docks, mooring buoys, and ramp densities within most reaches.
Some of the most highly impacted reaches on Bainbridge Island were located in Eagle Harbor (MA-5), including reaches 3131, 3141, 3143, and 3144 as well as reaches 3125 and 3126 associated with the Eagle Harbor/Wyckoff Superfund site on Bill Point (Figure B-49, Appendix C). In all cases, these reaches were characterized by exceptional amounts of fill and armoring, most of which encroached into the intertidal zone, high levels of point modifications, including docks and piers, and a high %TIA in the marine riparian zone.
Opportunities
Numerous opportunities exist for improving scoring of CF metrics at the individual reach level and perhaps on a sub area basis within MA-5, although the net improvement to the entire Eagle Harbor MA would likely be a significant challenge considering the current level of alterations (Figure B-14). The best opportunities for improvement should be sought before opportunities are lost or significantly limited further, especially opportunities to improve water quality and remove fill that can help restore some of the marsh/lagoon habitat permanently lost due to Superfund remediation. Regardless, best management practices would recommend actions that improve CF scores, such as minimizing and removing shoreline armoring in areas where erosion does not place structures at risk (e.g., Waterfront Park), maximizing light penetration in overwater structures, and improving the relative percentage of forested-to-impervious surface area in the marine riparian zone. Redevelopment may occur in an urban area at a faster rate than elsewhere, opportunities for restoration or enhancement might arise during the redevelopment of properties and infrastructure.
The EF scores were low (17.9) in MA-5 relative to the rest of Bainbridge Island (Figure B-11), despite the presence of at least three fish-bearing streams and some areas of documented sand lance and surf smelt spawn (Table A-4, Figure B-47). Low EF scores can be attributed to the low levels of overhanging vegetation, patchy distribution of eelgrass, and the paucity of geoduck resources in Eagle Harbor (Figures B-46 and B-48). Historic records document that herring once spawned in Eagle Harbor, but give no indication as to the reason for population declines (Chapman et al. 1941). Currently, high pollution levels prohibit the harvest and consumption of fish and shellfish from these waters.
