W. Federal Way, Washington Building Application Number: 99-104905 Parcel No.: 119600-3810 (Lots 1-4) Prepared for: Riverstone Homes, Inc. Dated. January 7, 2000 Prepared by: Jeffery S. Jones, Certified Professional Wetland Scientist ES TTE LEI JAN 1 01999 Ll 1.0 Introduction i . Jones and Associates, Inc. This study is for a stream determination and classification of an unnamed intermittent stream which flows into Puget Sound, located south of Redondo. This stream survey was conducted by Jeffery S. Jones, Certified Professional Wetland Scientist. 2.0 Methodology Habitat units identified, measured and evaluated using the USFS methodology "Stream Habitat Classification Inventory Procedures for Northern California" (McCann, 1990) and "Methods for Evaluating Riparian Habitats with Applications to Management" (Platts, 1987). Stream flow was estimated using the formulated Q(cfs)=A(area sf) x Velocity (fps). Streambanks were surveyed by Centre Pointe, Inc., licensed professional land surveyors. 3.0 Stream Location and Description The subject property is Lot 2 of Block33, Buenna Addition, at 268XX 2nd Ave. South, Federal Way, Washington. The stream reach adjacent to the subject property is a stream that discharges directly into Puget Sound. The source of this tributary is a concrete pipe, located 130 feet south of the southeast property corner of Lot 2 and street runoff from the development above. The drainage feature downstream has been altered by construction of single family residences and their associated yards. The drainage features ends at 292nd Ave. S.W. and apparently surface water is piped the rest of the way to Puget Sound. 4.0 Riparian Land Use Riparian land use is a combination of existing downstream residential and early successional forest. There has been some recent home construction downstream, but buffers are not apparent. Long sections of pipe must be present near several residences, that appear to be construction in the middle of the drainage. 5.0 Riparian Vegetation The riparian plant communities are existing landscaping and red alder (Alnus rubra) salmonberry (Rubus spectabilis) regrowth with areas of Himalayan blackberry (Rubus discolor). 6.0 Fish Habitat and Utilization Culverts, the steep gradient of the channel, shallow intermittent flows, and frequent eroding head -cuts, make the stream impassable to fish. Water quality is adversely affected by street runoff from the development above, which lacks storm water controls. According to existing residents, street runoff pours directly into the head of the channel. 7.0 Stream Classification and Setbacks City of Federal Way Code, Section 22-1, divides streams into two definitions, Major and Minor. Major streams are defined as "any stream, and the tributaries to any stream, which contains or supports, or under normal circumstances contains or supports resident or migratory fish. Minor stream shall mean any stream that does not meet the definition of a major stream." J40Jones and Associates, Inc. The unnamed stream has no fish use, therefore it is a minor stream. Section 22-1306, of the Federal Way Code, requires a 50 -foot setback from the ordinary high water mark of a minor stream. 8.0 References Federal Way City Code. 1999.

In addition, it covers all independent streams entering Puget Sound from the Du- wamish westerly to Alki Point at West Seattle, then south- erly through Fauntleroy, Burien, Des Moines, and Redondo beaches to Dash Point, north of Tacoma. Stream Description The Duwamish River Waterway lies in the industrial southern portion of Seattle. The lower 5.2 miles of the river are dredged, affording navigation for ships upstream to the First Avenue South Bridge (R.M. 2.5) at high tide. Barge traffic extends to the turning basin at the head of navigation (R.M. 5.2). Water dependent activities utilize lands bor- dering the lower 8 miles of waterway. The mile -wide valley floor and hillsides have heavy residential development. The width of the Duwamish varies from 500 to 1,000 feet in the lower 5.2 miles and from 150 to 200 feet up- stream to R.M. 11.0. The river in this area is under tidal influence and contains definite stratified layering of salt and fresh water below the turning basin. Velocities are dissi- pated as the stream enters the wider section of river and cur- rents converge with tidal pressures. Stream banks are sloped and diked to contain flows up to 11,000 cis. Stream bank sloughing and erosion present continuous maintenance problems, and the lower navigational channel must be dredged every third year. Small areas of sparse natural brush and deciduous trees line the bank. The bottom is primarily silt and mud in the navigation channel with compacted gravel in the upper section. Fifteen small independent streams enter Puget Sound within this section. These typical lowland drainages receive most of their flow from springs, lake outlets, rain and groundwater runoff. Miller, Bow Lake, and Des Moines creeks are the largest, each flowing down moderately steep hillside ravines before passing across gentle plateaus into Puget Sound. Miller Creek originates in Tub and Burien lakes. An impassable culvert occurs at R.M. 1.8; an impass- able falls at anile 2.7. This creek has undergone extensive alteration and total deterioration from the heavy residential and commercial growth in the Burien-Riverton Heights dis- tricts. Bow Lake Creek flows from the outlet of Bow Lake (R.M. 3.45) and enters salt water at Des Moines. A sewage treatment plant is located at approximately R.M. 1.0 with a partial block to fish migration from a cement weir with a 30 - inch drop, and an impassable cascade occurs at R.M. 1.5. The bottom composition is generally good in one-half of the lower mile of stream and provides suitable spawning area. Des Moines Creek is a short -nun stream originating from spring and groundwater sources. It flows west 1.9 miles through a fairly steep ravine to a series of cascades at R.M. 0.75, then crosses a shallow valley and enters Puget Sound between Des Moines and Zenith. Concentrated residential development has altered habitat through diversions, chan- nelization and encroachments. The stream is intermittent in nature and is generally dry during late summer and early fall. Salmon Utilization The Duwamish River Waterway is a transportation and rearing area. The lower river estuarial zone is vital to salmon as a transition area for adaptation of migrants to salinity changes. Fall Chinook, coho, and chum are the principal salmon species utilizing this watershed. Cohn and chum salmon are the only species that ascend Miller, Bow Lake and Des Moines creeks. Coho utilize Longfellow Creek, and coho and chum use the two unnamed tributaries in the southern portion of Poverty Bay near Redondo. Chum spawn in the lower portions of these short -run streams, while coho spawn and rear in their accessible lengths. Limiting Factors Water quality is the most serious limiting factor for salmon in the Duwamish waterway. The borderline dis- solved oxygen level below R.M. 5.2 is very crucial in August and September, particularly for adult Chinook. The salt- water wedge, created by dredging the navigation channel, varies with tidal cycles and contributes to the critical oxygen condition. Industrial wastes, domestic sewage, leachate from landfills, and storm runoff have all contributed to the water quality problems. Low flows and limited spawning gravel are the major limiting factors in the small independent streams. Siltation and water quality are also serious problems. Beneficial Developments " The METRO studies and waste disposal systems have benefitted the area's water quality. The Green River Hatchery produces excellent artificial runs of both Chinook and coho. The Howard Hanson Dam provides flood control for the lower Green River Valley and Duwamish area. Habitat Needs A Shorelines Management Plan that considers protec- tion of aquatic resources and habitat is needed to provide coordinated long-range development of this area. Rehabili- tation of the small independent streams would provide ex- cellent opportunities to local sports groups and community clubs for environmental improvement. PHOTO 09-10.
