Restoring the Necanicum Basin one project at a time
Restoration Projects
Explore some of the past and present habitat restoration work that we've tackled, including culvert replacements, riparian plantings, pollinator work, stream habitat enhancements, and more.
Current Projects
Gearhart Pollinator Project
-
Timeline: In progress
Invasive species removal and pollinator plantings along ~1.2 miles of trail. Species removed include english ivy, holly, himalayan blackberry, etc.. Pollinator patches include Douglas aster, Lupine, Camas and Goldenrod. Patch habitats are within 400-ft of Neacoxie Creek. The project is interested in expanding patch habitats to adjacent properties not directly on trail.

Lower Coho Creek Fish Passage
-
Timeline: In progress (implementation in summer of 2023)
Replacing two ~30" pipe culverts with a 19' open bottom, multiplate arch and natural stream simulation through the stretch of the culvert passing. Coho Creek is a winter steelhead and Coho bearing stream. The replacement of the current culvert system will connect the lower portion of Coho Creek with the upper creek culvert replacement led by the watershed council nearly a decade ago. Upon completion, Coho Creek will have over 0.75 miles of newly connected fish passable habitat.

Shangrila Wetlands Vegetation Enhancement
-
Timeline: In progress
Invasive species removal and construction of vegetation enclosures that will include both young and mature wetlands-specific species. This project is designed to increase the functionality of the Shangrila Wetlands complex by adding plant biodiversity and density to the wetlands border with the Mill Ponds habitat in Seaside. The wetlands system is adjacent to the fish bearing Shangrila Creek, a tributary of the Neawanna Estuary and Necanicum system.

Past Projects
Circle Creek
-
Timeline: Completed in 2012
Information: Over 55 pieces of large wood were installed along a single reach of Circle Creek in Seaside, Oregon.
Dichter Road Passage & Stream Enhancement
-
Timeline: Completed in 2012
Information: Replaced a 6-ft wide perched culvert with a 16-ft wide steel bridge. An additional culvert located above the initial project site was also removed, at the landowner’s expense. Additionally, 80 pieces of large wood were placed within a 0.9 mile reach up- and down-stream of the road crossing to increase pool habitat and channel complexity, increase winter/off-channel refuge habitat, dissipate stream energy and retain bedload materials, and distribute fine sediments. A variety of native conifers (Sitka spruce, western hemlock and western red cedar) were planted throughout the project area to increase the potential of future LWD recruitment and the change the composition of the riparian area from hardwood dominated to mixed conifer/hardwood.
Upper Coho Creek Culvert Replacement
-
Timeline: Completed in 2012
Underneath Spruce Rd., a 20-foot tall ridgeline road to the new school complex, a 5-foot pipe culvert was replaced with a 19' open bottom arch culvert with reconstructed stream simulation. The replacement of this culvert was phase I of a multi-phase Coho Creek restoration plan.
Neitzel Farm Restoration
-
Timeline: Completed in 2012
Information: The NWC planted approximately five acres of riparian, floodplain, and wetland areas. Exclosures were installed around Cascara and crabapple plants to protect from grazing. Plantings produced a substantial increase in functional wetlands and floodplain.
Bergsvik Creek Large Wood Placement
-
Timeline: Completed in 2021
Over a mile of enhanced salmonid habitat on the upper Bergsvik Creek reach near Highway-53. Logjams, some with root wads still in-tact, and strategically anchored Christmas trees, have been placed to greatly increase the quality of habitat for spawning Coho and Steelhead.
Necanicum Riparian Restoration & Tree Release
-
Timeline: Completed in 2012
Information: Invasive species removal (knotweed, blackberry, ivy and others) and replacement with spruce, cedar, big leaf maple, etc. on nearly 8,000’ of streamside frontage. Plantings also included crabapple, willow, twinberry and more.
Upper Circle Creek Storm/Floodplain Restoration & Fish Passage Improvement
-
Timeline: Completed in 2012
Information: 8 road stream crossings were removed, 3 permanently and the other 3 were replaced with culverts meeting state fish passage standards. Over 300 logs were installed at a 3 log/100 lineal feet of stream to improve habitat and fluvial morphology. Native plantings included nearly 400 Sitka spruce and wilding Scirpus mircoarpus and 5100 lineal feet of road obliteration was completed.
Hawley Creek Fish Passage and Habitat Improvement
-
Timeline: Completed in 2007
Information: Five road stream crossings were removed, four permanently. A bottomless arch culvert was installed in the final crossing. Over 2,500 feet of forest road system were obliterated and prepared for revegetation. Over 100 pieces of large wood were installed within the floodplain. 150’ of stream bank was sloped and reshaped as well as breaching of a man-made dike allowing for connectivity of the former floodplain. Wetlands areas were created as well as ample native vegetation installation.
Joe Creek Restoration
-
Timeline: Completed in 2011
Information: Distributed large wood installations at nine different sites along 0.4-miles of stream reach. 37 key pieces (34 of which had rootwads) and 17 secondary pieces (12 with rootwads) were placed. In addition around 550 conifers were planted along the riparian area to encourage future wood recruitment.
South Fork Necanicum Fish Passage and
In-stream Habitat Improvement
-
Timeline: Completed in 2010
Information: Restoration activities included the addition of large wood (56 key logs w/rootwad attached, 3 key logs w/o rootwad, and 34 additional non-key pieces distributed among 13 sites) through a 0.75 mile reach of two tributaries), as well as the replacement of an impassable culvert with a prefabricated concrete bridge.
Arresting Policeman’s Helmet
-
Timeline: Completed in 2020
Information: In partnership with the North Coast Land Conservancy, the NWC conducted a 3-year treatment project for policeman’s helmet. The project incorporated a large-scale outreach effort to engage landowners and partners. Over the project’s life 7 river miles and 152 acres of policeman’s helmet were treated with 35 different landowners participating in removal or surveying. Almost 3,000 plants were installed in place of the removed policeman’s helmet.
