Briefly describe the vegetation and habitat conditions on the property. nel Terrestrial environments in the project vicinity are fragmented and disturbed, consisting mainly of commercial, industrial, and residential zones along 1-5 and SR 18 corridors. Several small stands of second and third growth forest, mixed deciduous/conifer forest, as well as wetlands and maintained grassy areas occur on undeveloped lots in the project vicinity. There are several wetlands within the project area totaling 6.6 acres. They contain forest, shrub, and emergent plant communities. Wetland vegetation within the study area typically consists of: Oregon ash, red alder, black cottonwood, western red cedar, Douglas spirea, salmonberry, willow species, reed canary grass, lady fern, slough sedge, water parsley, and creeping buttercup. Wetlands in the project area generally provide moderate levels of biological, chemical, and physical functions. Many of them have hydrology inputs or outflows associated with highway -related culverts. Although many of the wetlands are compromised by urban development and other development pressures, a few wetlands provide quality habitat value. There are also 4 acres of riparian habitat along the two streams in the project area, designated 10-0016a and 10-0016 by WDFW. Both are part of the Hylebos Creek watershed and are tributaries to the East Branch of Hylebos Creek, located southeast of the SR 161 portion of the project corridor. Stream 0016a runs dry in the summer; Stream 0016 has some summer flow. Both riparian corridors are fragmented, reducing their use as wildlife corridors. 5k. Describe how the property is currently being used. hel The Triangle Project area encompasses approximately 2 miles along 1-5 (MP 140.86 to MP 142.77) and 1 mile of SR 18, (MP 2...42B to MP 0.82) of a designated transportation corridor within the State's right of way (ROW). The project will also make improvements to 0.5 miles of SR 161 (MP 34.15 to MP 34.61) and 936 feet of South 356th Street(from SR 161 to 1-5). In this area, 1-5 is an Urban -Interstate with full limited access control. SR 18 is an Urban -Principal Arterial with full limited access control. SR 161 is an Urban -Minor Arterial with partial limited access control. South 356th Street is a dead end residential street with some businesses and vacated housing.

None of planned work is within the 100 year flood plain. 1. Flyover ramp: One flyover ramp will be constructed at westbound 18 going southbound on 1-5 (Structure ES-01 on sheet 8). The overpass does not cross any water bodies. Stream 0016a is approximately 230' west of the new bridge. Wetland M (sheets 14 and 15) is approximately 600' east of the new bridge. This end of the bridge is adjacent to Stream 0016a; the bridge runs east — south, with Stream 0016 approximately 230' west and Stream 0016a approximately 50' to the west. Construction of the bridge and abutments will not impact these or other aquatic resources. Bridge structures will consist of precast concrete girders and steel tub box girders. Bridge foundations will be a combination of spread footings and drilled shaft footings. Construction of bridge structures and walls will require the use of drilling rigs and augers, pile drivers, jackhammers, slurry processing equipment, concrete pumping equipment, compressors, generators, and pumps. 2. Channel modification: Stream 0016a will be moved approximately 45 feet to the west, and the channel reconfigured. Work will be done in the dry and a bypass pipe will be used during construction to divert possible storm flow. Also, in the Form #23 5 of 17 it t'I Last Update: 10/22/08 EX BIT 't �' NW sector of the project, an existing culvert in the NW cloverleaf will be removed and the restored stream channel (Stream 0016a) will be daylighted for approximately 250'. This work will be done using backhoe, front loader, dump truck, and other heavy equipment as needed. See sheets 5 and 6. 3. Culvert: the project will impact five culverts. • the culvert conveying Stream 0016a under 1-5 will be extended 85' to the west (see sheet 4), • the culvert conveying Stream 0016a under the SW cloverleaf will be extended 50' to the south (see sheet 8). • the culvert conveying Stream 0016a under SR 18 will be extended 50' to the north (see sheet 9) • a new, fish passable culvert will be installed under the off ramp to 356"' St. S to convey Stream 0016a; this culvert will be approximately 65' long (see sheets 5) ■ the culvert conveying Stream 0016 under SR 18 (see sheet 14) will be modified so that the connection point for offsite storm drainage will be 60' to the north Construction will be done in the dry using a backhoe, crane, front end loader, dump truck, and other specialized equipment as needed. 4. Ditch: there are 4 jurisdictional ditches in the project area. 2 jurisdictional ditches are being regraded. See plan sheet 13 for ditch A4. For ditch C1, see Rapanos report, figures 2 & 4. 5. Road: The proposed project includes the removal of existing roadways, grading, laying new roadway sub grade, and paving with asphalt and concrete pavements. Road building in the project area will fill portions of Stream 0016a (sheets 5 and 6) and two wetlands (M and N: sheets 14 and 15). Those portions of the stream will be relocated. The relocation is associated with the proposed channel modification. At -grade construction work for new lanes and shoulders will require demolishing or removing existing asphalt concrete surfaces, clearing and grading adjacent areas, laying base aggregate foundations, and topping with asphalt surfaces. These activities would most likely require the use of construction equipment, such as backhoes, excavators, pavement grinders, jackhammers, concrete pulverizers, front loaders, and grading and paving equipment. 6. Stormwater Facility: Two existing stormwater treatment ponds will be expanded to treat new impervious surface. One of the existing treatment ponds (Pond S) is in the SE sector between 1-5 and SR 161/Enchanted Parkway (sheet 3). This pond discharges into Stream 0016a. The other existing treatment pond (Pond R) is in the NW quadrant of the project, on the west side of 1-5 and just north of 344th. Stream 0016a runs alongside this pond (Pond R), and Wetland Q is approximately 100' north of the pond. Pond R discharges into Stream 0016a. Pond R does not discharge into Wetland Q, nor does Stream 0016a enter Pond R. A new pond (Pond C) will be constructed in the SE quadrant; this area is bordered by Stream 0016 to the east (see sheet 14). No wetlands are affected by this new pond construction. A second new pond (Pond B) will be constructed in the SW clover leaf interior. There is a very small wetland in this area (Wetland U), and Stream 0016a runs approximately 30' east of where the new pond will be constructed (sheets 8 and 9). Wetland U will not be affected by the new pond construction. The new pond will be adjacent to Wetland U. Two ecology embankments (median filter drains) are included in the project design. Both ecology embankments are located on the north side of SR 18, east of 1-5. Wetland M is located between the two ecology embankments, which are approximately 30' to the east and west of Wetland M. The eastern embankment also passes through Wetland N. The combined length of the two embankments is 1165' (western embankment = 245', eastern embankment = 920'). Plan sheets 14 and 15 show the general area where Wetlands M and N are located, though the ecology embankments are not shown on the JARPA drawings. However, the design of both ecology embankments is according to standard specification. Expansion of existing facilities and construction of new facilities will be done using a backhoe, front loader, dump truck, and other heavy equipment as needed. 7. Utility line: This project will re -locate a number of utility lines, including electrical, fiber optic, phone and water. These lines are located throughout the project area. Utilities will be relocated both before and during project construction. Utility work will occur in existing roadway and within impacts described as part of the project construction. No additional impacts to aquatic resources have been identified that have not already been accounted for in other sections. 8. Other: Construct Stream and Wetland Mitigation Site. Wetland and stream impacts will be mitigated for at the Corrington Mitigation Site, address is 933 South 364`h Street # T, Federal Way, WA 98003. The North Fork of West Hylebos flows south along the western edge of the property. There are several wetlands on the site supported by both Form #23 6 of 17 I Last Update: 10122108 elevated seasonal ground water levels and year round surface water flows. The site also contains a man-made pond and small perennial stream. The northern parcel is primarily maintained lawn, with some large cottonwoods and willow trees bordering the North Fork of West Hylebos Creek. Construction of the mitigation site will be done with heavy equipment such as a backhoe and front loader and dump -truck. Construction will be completed in accordance with approved mitigation report. 6e. What are the start and end dates for the construction of the project?

Of these alternatives, WSDOT chose the alternative with the fewest environmental impacts. The preferred alternative limits expansion of 1-5 west into a string of wetlands along Stream 016A, minimizes the area of the 1-5 SR 18 interchange and avoids connecting SR 161 northbound directly to 1-5 northbound through Wetland AB. Of the seventeen wetlands in the project vicinity, the project will affect only two wetlands: one small (0.20 acre) wetland (N) and a small part (0.03 acre) of Wetland M. WSDOT proposes to construct a retaining wall, rather than the standard sloped fill, to minimize the extent of fill in Wetland M. WSDOT will also minimize other impacts to streams, stream buffers and wetland buffers through the construction of other walls and steepened side slopes. 7d.

Provide a summary of what the compensatory mitigation plan is intended to accomplish, and describe how.a watershed ap2roach was used to design the Ian_ neIL) The mitigation plan was designed to compensate for wetland impacts by creating and enhancing wetlands and associated buffers and providing a large area of stormwater flow retrofit (34 acres) Flashy flows and associated erosion and habitat impacts have been identified as a limiting factor in the Hylebos Creek watershed. Therefore, mitigation for stream impacts focused on reducing peak flows. The Hylebos Creek watershed is characterized by mostly urban and suburban development with a couple of large pockets of natural habitat in areas zoned low density. Major transportation corridors, large commercial developments, residential complexes and housing developments limit the quality and functions provided by wetlands in the watershed. The WSDOT approach was to mitigate for unavoidable project impacts to wetlands within the transportation corridor, where wildlife functions are low, by creating and enhancing wetlands within an area containing large pockets of natural habitat where habitat functions are high. The Corrington mitigation site is located near many preserved natural areas along the North Fork of the West Hylebos. The site provides the opportunity to maximize wildlife functions because it is part of a wildlife corridor. This site is within a large wetland complex and has a fish bearing stream along the western edge of the property. 7j.

If you have already completed 7i, you do not need to restate: your answer here. I,elr1 The WSDOT Triangle Project mitigation plan compensates for stream impacts by reducing peak flows, bank erosion, sedimentation and by creating additional stream channel and associated buffers. The Hylebos Creek watershed is primarily urban and suburban development. The WRIA 10 Limiting Factors Analysis identified peak flows, bank -erosion, sedimentation and water quality as some of the key components limiting fish production in the Hylebos Creek sub basin. Stream 0016a, which drains SeaTac Mall and other commercial facilities, produces flashy, high peak flows because of the large amount of impervious surface in the watershed. When originally constructed these commercial facilities provided only minimal stormwater detention while creating significant new impervious surface. Stream 0016a flows into the East Hylebos. The high peak flows from Stream 0016a erode stream banks in the steep reaches of the East Hylebos. Further downstream (in the lower flat reaches), high peak flows limit sediment deposition and prevent establishment of spawning habitat. Control of peak flow is a critical first step in improving the East Hylebos, prior to habitat creation, because the peak flows will damage habitat structures and the sediment will bury habitat structures andspawning ravel if they are created prior to controlling peak flows. Therefore, a critical part of WSDOT's stream Form #23 v 10 of 17 E X H I r Update: 10122108 mitigation package is providing stormwater detention for the equivalent of 34 acres of impervious surface on Stream 0016a prior to its confluence with the East Hylebos. Treatment of this storm water will also improve the water quality of the East Hylebos. In addition, the proposed mitigation plan will provide 765 feet of new channel and 2.45 acres of stream buffer creation or enhancement to mitigate for 745 feet of stream channel filled and 4.64 acres of stream buffer loss. Mitigation for existing fish barriers on Stream 0016a within the project area will consist of stream enhancement activities at WSDOT's Corrington mitigation site. The Corrington mitigation site is located along the North Fork of the West Hylebos, on South 364th street in Federal Way. This mitigation approach provides quality habitat where existing anadromous fish use is known and well documented along the North Fork of the West Hylebos, rather than along Stream 0016a where the fish use is undocumented and unlikely because of the high peak flows and prolonged periods of no flow. A side channel of 430 linear feet (0.05 acre) will be constructed at the Corrington Mitigation site to provide fish rearing habitat. This new channel will connect to the existing pond (0.14 acre) at the site, and will meander to the south and west to where it will join the North Fork of the West Hylebos. The groundwater base flow entering the pond will supply a constant source of clean, cool water for the creek that will help provide high quality habitat for fish species. Habitat structures will be installed to improve fish habitat in the pond. Also, the riparian corridor will be enhanced by planting trees along the North Fork of the Hylebos. This mitigation will provide access to more usable habitat for resident and anadromous fish species than that provided through the removal of existing fish passage barriers on Stream 0016a. 8f. Please describe in detail the source and mature of the fill material, the amount that will b.e used, @lid how and where it will be placed into the waterbody. help] As part of the re-channelization of Tributary 0016a, WSDOT will fill approximately 495 linear feet of existing channel with clean fill material obtained from onsite (400 cubic yards of fill). 8g. For excavating or dredging impacts., please describe the type of material proposed to be excavated or dredged, the methods to be used, the amount of material to be removed, and where the material will be. disposed. ti atn The project will create or restore approximately 765 linear feet of seasonal stream habitat on Tributary 0016a. Approximately 250 linear feet of stream will be restored from culvert removal northwest of the 1-5/SR18 interchange. The project will excavate approximately 515 linear feet of new stream channel west of the existing channel (1000 cubic yards excavation); the existing channel will be filled. Any surplus material excavated during the project that is not returned to the project site will be disposed of at an approved upland location.

Briefly describe the vegetation and habitat conditions on the property. t,nlr,l The Corrington site is in the West Hylebos sub basin, and is surrounded by large tracts of undeveloped land owned by the City, WSDOT, and other public agencies. The North Fork of West Hylebos flows south along the western edge of the property. There are several wetlands on the site supported by both elevated seasonal ground water levels and year round surface water flows. The site also contains a man-made pond and small perennial stream. The northern parcel is primarily maintained lawn, with some large cottonwoods and willow trees bordering the North Fork of West Hylebos Creek. The southern parcel is dominated by reed canary grass and Himalayan blackberry. Due to its landscape setting and relative lack of development the site provides high -quality fish and wildlife habitat functions. 5k:.I7escribe how the property is currently being used. The mitigation site was a residence that has been demolished. At the time of its purchase by WSDOT, the Corrington site was undeveloped except for a mobile home and small garage situated in the northern portion of the site. The mobile home sat on a broad shelf of fill material that slopes gently down to a constructed pond. The garage was located in the northwest comer of the property and was accessed by a narrow driveway constructed a thin layer of gravel and fill material. In addition, a pump house was located in the east -central portion of the site. These structures were removed by WSDOT in the summer of 2008 and now there are no structures on the property. The Corrington mitigation site is zoned IRS 35 (residential-35,000 sf). 51. Describe how the adjacent propert currently being used_ ne The Corrington Mitigation site property is hounded to the north by a large (36-acre) undeveloped parcel, consisting primarily of forested wetlands, owned by the City of Federal Way. Properties to the east, south and west are private lots containing single family homes. Land use zoning adjacent to the Corrington mitigation site is IRS 35 (residential-35,000 so. 5rn. Describe the structures (whether above or below ground) currently located on the property, including their purpose. iP l All structures located on the former residential site have been removed or demolished (trailer, garage, and pump house). 5n..
