Carkeek Park Marine Preserve

WAC 220-16-830: "Carkeek Park Marine Preserve" is defined as two sections of tidelands owned by the City of Seattle and the water column above those tidelands down to 4.5 feet below MLLW at Carkeek city park, with a southern section bounded on the south by a line projected perpendicular to the beach from 122° 22' 49.0" W, 47° 42' 31.7" N and bounded on the north by a line projected northwest from 122° 22' 47.41" W, 47° 42' 43.51" N, and with a northern section bounded on the south by a line projected due west from a point 300 yards north of 122° 22' 47.41" W, 47° 42' 43.51" N and bounded on the north by a line projected due west from a point 500 yards north of 122° 22' 47.41" W, 47° 42' 43.51" N. Effective since 5/1/2005.

Prominent and unique features

Carkeek Park Marine Preserve is bisected into north and south segments by the sand and mud delta of Pipers Creek, an active salmon-bearing stream draining parts of north Seattle. The south section is composed primarily of sand, gravel and cobble with small, scattered boulders. Small-sized sediments deposited from the creek tend to accumulate into sand bars to the south. The north beach has smaller sand bars and larger boulders as one proceeds away from the creek. Clay benches are found in places, often covered under several inches of sand and gravel. The backshore of both sections is formed by riprap associated with the adjacent railroad tracks.

Description of fish, bird, and mammal resources at the site

Both segments of beach support a wide variety of invertebrate species plus a moderate growth of seaweeds. The lower intertidal hosts eelgrass beds that extend into the subtidal supporting additional invertebrates, residential and migratory waterfowl and numerous fishes, including juvenile salmon. Adult salmon may also be present just offshore, particularly each late fall as spawning chum salmon return to Pipers Creek.

The low-subtidal also provides substrate for seasonal kelp beds, providing habitat for dozens of species of fishes. Harbor seals, California sea lions and orca whales have been observed in offshore areas.

Programs in place to manage the site

The Seattle Parks and Recreation Dept. provides naturalists to monitor the park and provide educational programming. The Seattle Aquarium Beach Naturalist program provides extensive beach interpretation in the late spring and summer. In addition, Seattle Aquarium Citizen Science staff and volunteers conduct periodic ecological surveys at the site for long-term monitoring and science education opportunities.

Issues of concern

Educating the public about the boundaries of these closed areas as well as their purpose will be crucial to success. The Seattle Aquarium Beach Stewards program will be important in addressing this.

Due to the popularity of these areas, impacts from increased non-consumptive use are a potential concern (trampling, etc.).

Performance measures

Continued or increasing use for education, watchable wildlife users, and non-consumptive uses.

Maintenance or increase in numbers and diversity of intertidal organisms.
