SITE MAP GAS MAIN EXTENSION AT MADSFN CREFK I 3.0 Stream Assessment Methods The project study area is defined as 100 feet upstream and downstream from the proposed stream crossing location a nd 100 feet around the bore pit locations in Renton. Streams outside of the study area were not forma ll y delin eated , but assessed based on characteristics visib le from public rights of way or avai lable information in existing documents and studies , maps and/or aerial photographs. 3.1 Document Review Existing documents reviewed for this stream assessment include the following : • C ity of Renton Surface Water C lassifications and Wetlands Map (20 16) • C ity of Renton Planning Land Use Map (2015) • WDNR Forest Practices Appli cation Review System (FPARS) (2016) • WDFW Priority Habitat Species web app li cation (2016a) • WDFW Sa lm onScape web application (2016b) • USDA NRCS web so il survey (2016) • Salmon and Steelhead Habitat Limiting Factors Report for the Cedar-Sammamis h Basin (Kerwin 2001) • Elliott Bridge No .3 166 Replacement Environmental Impact Statement (King Cou nty 2003) These docum ents provide reference information on the soils, streams, land use , and aquatic and terrestrial habitat in the study area. 3.2 Field Investigation Field investigat io ns for the project were conducted by HOR biologists on November 28, 2016. Streams T o determine the ordinary high water mark (O HWM) of freshwater streams in th e project area, HOR biologists utilized Ecology's (Olse n a nd Stockdale 2010) guidance for OHWM iden tification , which is based on the Shoreline Management Act (RCW 90 .58 .030(2)(b) and Washington Adm inistrative Code (WAC 173-22-030(11 )). Ecology defines the "o rdinary high water mark" as: "on all lakes, streams, and tidal water is that mark that will be found by examining the bed and banks and ascertaining where the presence and action of waters are so common and usual, and so long continued in all ordinary years, as to mark upon the soil a character distinct from that of the abutting upland, in respect to vegetation as that condition exists on June 1, 1971 , as it may naturally change thereafter, or as it may change thereafter in accordance with permits issued by a local government or the department: PRO VOIDED , that in any area where the ordinary high water mark cannot be found, the ordinary high water mark adjoining saltwater shall be the line of mean higher high tide and the ordinary high water mark adjoining fresh water shall be the line of mean high water." HOR biologists looked for physica l in d icators including , but not limited to, a natural scour line impressed on the bank, d ist ribution of upland and water tolerant vegetation, and bed and banks. G as Main Ex tens ion at Mad sen Creek Stream A ssessment M em o 7 Th e locati ons o f O HWM for ide ntifi e d streams within the study area were su rveyed u sing the Trimble GE0-7X G PS device . Th e resulting data we re incorp orated into Figure 2 . The C ity of Renton classifies streams based on the state o f Was hington's Water Typing Syste m est ablished in WAC 222-160-030. Streams are regula ted by th e C ity o f Re nton per the critical areas regul ations (RMC 4-3-050 ). Table 1.

Gas Main Extensio n at Madsen C reek Stream Assessment Memo 8 The City of Renton measures stream buffers according to the following guidance (RMC 4 -3- 050 .F. 7 .c.ii): Buffer: The boundary of a buffer shall extend beyond the boundaries of the stream or lake to the width applicable to the stream/lake class as noted in subsection G2 of this Section, Critical Area Buffers and Structure Setbacks from Buffers Where streams enter or exit pipes, the buffer in this subsection shall be measured perpendicular to the OHWM from the end of the pipe along the open channel section of the stream. 4.0 Findings 4.1 Streams ' ' .' The study area is located in the Madsen Creek subbasin within Washington Water Resource Inve ntory Areas (WRIA) #8 (Ceda r/ Sammamish). HOR biologists delineated the OHWM of Madsen Creek within the study area. Table 3 (below) summarizes the stream, type and buffer width . Table 3. Summary of Streams in the Project Study Area Stream Name Tributary To Stream Type in Study Area Stream Buffer Width Madsen Creek Cedar River Type F 115 feet 4. 1. 2 Madsen Creek Madsen Creek is located in the City of Renton and in unincorporated King County. The headwaters of Madsen Creek originate in a residential neighborhood on the south side of the Cedar River Va lley, just north of Lake Youngs, approximately 2 miles southeast of the project area. Several small tributaries converge with the main stem channel before descending north down the valley slope toward the Cedar River. South of Maple Valley Road, Madsen C reek flows westerly along the highway for approximately 650 feet and crosses the highway through a box cu lvert (King County 2003). North of Maple Valley Road , Madsen Cree k flows west for approximate ly 110 feet west along the Cedar River Trail before crossing 149th Avenue SE in a concrete box culvert. The culvert was submerged and was not visible during the site visit. On the upstream portion of the culvert crossi ng , the bankfull width was measured at approximately 9 feet with a water depth of 18 inches . The left bank height was measured at 10 inches above surface water, and the right Gas Main Extensio n at Madsen Creek Stream Assessme nt Memo 9 bank height was measured at one in c h. The stream substrate predominantly co nsisted of fine silts. The area is mapped as Newberg silt loam , which tend to be well drained soils (USDA NRCS 2016). Vegetation on the stream bank is dominated by Himalayan blackberry (Rubus armeniacus), red osier dogwood (Camus sericea), snowberry (Symphoricarpos a/bus), giant horsetail (Equisetum giganteum), scouring rush (Equisetum hyemale) and nootka rose (Rosa nutkana). Reed canarygrass (Pha/aris arundinacea) was observed more dominant near 149th Avenue SE but thinned out upstream where thimbleberry (Rubus parviflorus) became more dominant. Trees observed include red alder (A/nus rubra), black cottonwood (Popu/us ba/samifera), Sitka willow (Sa/ix sitchensis) and Pacific willow (Salix lasiandra). See photos 5 , 9, and 10 for vegetation . At the culvert crossing, a man-made drainage ditch (D itch 1) was identified along the east side of 149th Avenue NE. HOR biologists observed that the majority of the stream flow being diverted to this ditch at the time of field investigation. Ditch 1 is approximately 4 feet wide with constructed banks 2 feet in height (Photo 8). The water level was observed at approximately 5 inches. The channel substrate consisted of fine silts, sands and small 0.5-inch cobbles. The ditch was mostly unvegetated with some sparse grasses , blackberry and soft rush (Juncus effusus). Ditch 1 runs north along 149th Ave nue NE for 850 feet and discharges into the Cedar River at River Mile (RM) 5 (Kerwin 2001). Downstream of the culvert crossing on the west side of 149th Avenue SE , not mu c h flow was observed in the stream channel. The bankfull width of the channel was observed at approximately 11 feet with a water depth of 19 inches. The bank height was observed at 4 inches above water surface on both the left and right banks . The substrate was predominantly fine silts. Vegetation is dominated by Himalayan blackberry and alder trees . Some reed canarygrass and one big leaf maple (Acer macrophyllum ) tree was observed along the stream. Approximately 130 feet from the culvert crossing , a patch of Japanese knotweed (Po/ygonum cuspidatum), a few scattered birch trees (Betula papyrifera), and snowberry were also observed . Madsen Creek flows west for approximately 370 feet from the culvert crossing and then flows north for approximately 1,300 feet before entering the Cedar River. 4.2 Ecological Functions Riparian areas are the zones where aquatic and terrestrial ecosystems interact (May 2000). Riparian vegetation along Madsen Creek provides shade , bank stability control, woody debris recruitment , organic nutrient input, sedimenUnutrient filtering, and food supply for terrestrial species and birds . Terrestrial species that likely utilize the study area include small mammalian species such as raccoons, opossums , squirrels, skunks , moles, voles, and rats . Deer, mink, and coyotes may also use the study area for foraging. Birds commonly found in the study area include songbirds, hawks, owls , bald eagles, ospreys (King County 2003). Birds observed at Madsen Creek during the field visit included spotted towhee (Pipilo maculatus), song sparrows (Me/ospiza me/odia), black-c apped chickadee (Poecile atricapillus), and American robins ( Turd us migratorius). Outside of the study area, a perched bald eagle (Haliaeetus leucocephalus) and a soaring Coo per's hawk (Accipiter cooperii) were also observed along the Ceda r River near the cul-de- sac at the northern end of 149th Avenue SE , approximately 800 feet from the project area . Gas Main Extension at Madsen Creek Stream Assessment Memo 10 Acco rding t o the Priority Habit at s and Species (PHS) list , no terrestrial priority habitat species were mapped in th e project a rea (WDFW 2016a). Acco rding t o the WDFW Sa lmon Scape and PHS (2016a and 2016b), Madsen Creek ha s docu m en t ed occ u rre nces of fall Chinook (Oncorhynchus tshawytscha}, co ho (0. kisutch), winter stee lh ead (0. mykiss), sockeye (0. nerka) and re sident coastal cutthroat (0. clark1). Breeding habitat for coho , winter stee lh ead and sockeye is documented in Madsen C ree k. Chinook and steel head are f ede ra ll y threatened species. 5 .0 Project Impacts 5.1 Stream Impact s No permanent o r temporary impacts to Madsen Creek will occur as a result of thi s project. No in-water work is associated with the propo sed project and no trees or riparian vege tation will be removed as a re s ul t of this project . 5.2 Stream Buffer Im pacts Madse n Creek is a Type F stream and therefore has a required buffer width of 115 f eet (RM C4- 3-050 .G.2). Pe r C it y of Renton code req uirements, the stream buffer is meas ured perpendicular to the OHWM from the end of th e cu lvert along an ope n c hanne l section of a stream (RM C 4 -3- 050.F. 7.c .ii). Bore pit s 1 and 2 are located within the stream buffer of Madse n Creek , and Bore pits 3 and 4 are located outs ide of the stream buffer us ing thi s definition (see Figure 2 , Sit e Map). The proposed locatio n of Bo re Pit 1 is partly within a paved and a grave l area (Photo 1 ). The bore pit will disturb approxi mately 3 by 5 fe et of as phalt and gravel. Bo re Pit 2 is located in a grave l shoulder north of Bore Pit 1 adjacent to the Cedar River Trail. T he bore pit wi ll di sturb approx im at e ly 5 by 5 feet of gravel. No vegetation clea ri ng or tre e removal is re quired t o insta ll Bore pits 1 and 2 . As a result , this project is not expected to have any stream buffer impacts to Madsen Creek. 6.0 Mitigation The p ropos e d project avoids impa cts to Madsen C re ek and its buffers as th e project w ill not requi re in -water work or remove any woody vegetation in th e stream buffe r within the City of Renton. Bore pit 4 , lo cated in the Ceda r Ri ve r flo od plain would require minor temporary distu rban ce to lawn grass; however, any disturbed area wo ul d b e rest ored t o preconstruction co n dition . Ove rall the proposed activity is not expected to alter or degrade the ecological functions in the project area ; therefore , no mitigation is required for thi s project.. 7. 0 References Ci ty of Ren ton . 2016.

Q) [/) BMP C103: High Visibility Plastic or Metal Fence +••P,c10,+ Purpose: Fencing is intended to: (1) restrict clearing to approved limits; (2) prevent disturbance of sensitive areas, their buffers, and other areas required to be left undisturbed; (3) limit construction traffic to designated construction entrances or roads; and, (4) protect areas where marking with survey tape may not provide adequate protection. Conditions of Use: To establish clearing limits, plastic or metal fence may be used • At the boundary of sensitive areas, their buffers, and other areas required to be left uncleared. • As necessary to control vehicle access to and on the site. Design and Installation Specifications: High visibility plastic fence shall be composed of a high-density polyethylene material and shall be at least four feet in height. Posts for the fencing shall be steel or wood and placed every 6 feet on center (maximum} or as needed to ensure rigidity. The fencing shall be fastened to the post every six inches with a polyethylene tie. On long continuous lengths of fencing, a tension wire or rope shall be used as a top stringer to prevent sagging between posts. The fence color shall be high visibility orange. The fence tensile strength shall be 360 lbs.if!. using the ASTM 04595 testing method. Metal fences shall be designed and installed according to the manufacturer's specifications. Metal fences shall be at least 3 feet high and must be highly visible. Fences shall not be wired or stapled to trees. Maintenance Standards: If the fence has been damaged or visibility reduced, it shall be repaired or replaced immediately and visibility restored. BMP C235: Straw Wattles .,.,,,,,,. Purpose: Straw wattles are temporary erosion and sediment control barriers consisting of straw that is wrapped in biodegradable tubular plastic or similar encasing material. They reduce the velocity and can spread the flow of rill and sheet runoff, and can capture and retain sediment. Straw wattles are typically 8 to 10 inches in diameter and 25 to 30 feet in length. The wattles are placed in shallow trenches and staked along the contour of disturbed or newly constructed slopes. See Figure A for typical construction details. Conditions of Use: Disturbed areas that require immediate erosion protection. Exposed soils during the period c,f short construction delays, or over winter months. On slopes requiring stabilization until permanent vegetation can be established. Straw wattles are effective for one to two seasons. If conditions are appropriate, wattles can be staked to the ground using willow cuttings for added revegetation. Rilling can occur beneath wattles if not properly entrenched and water can pass between wattles if not tightly abutted together. Design and Installation Specifications: It is critical that wattles are installed perpendicular to the flow direction and parallel to the slope contour. Narrow trenches should be dug across the slope on contour to a depth of 3 to 5 inches on clay soils and soils with gradual slopes. On loose soils, steep slopes, and areas with high rainfall, the trenches should be dug to a depth of 5 to 7 inches, or 1 /2 to 2/3 of the thickness of the wattle. Start building trenches and installing wattles from the base of the slope and work up. Excavated material should be spread evenly along the uphill slope and compacted using hand tamping or other methods. Construct trenches at contour intervals of 3 to 30 feet apart depending on the steepness of the slope, soil type, and rainfall. The steeper the slope the closer together the trenches. Install the wattles snugly into the trenches and abut tightly end to end. Do not overlap the ends. Install stakes at each end of the wattle, and at 4-foot centers along entire length of wattle. If required, install pilot holes for the stakes using a straight bar to drive holes through the wattle and into the soil. At a minimum, wooden stakes should be approximately 3/4 x 3/4 x 24 inches. Willow cuttings or 3/8-inch rebar can also be used for stakes. Maintenance Standards: Stakes should be driven through the middle of the wattle, leaving 2 to 3 inches of the stake protruding above the wattle. Wattles may require maintenance to ensure they are in contact with soil and thoroughly entrenched, especially after significant rainfall on steep sandy soils. Inspect the slope after significant storms and repair any areas where wattles are not tightly abutted or water has scoured beneath the wattles. BMP C123: Plastic Covering +••,,c12,+ Purpose: Plastic covering provides immediate, short-term erosion protection to slopes and disturbed areas. Conditions of Use: Plastic covering may be used on disturbed areas that require cover measures for less than 30 days, except as stated below: • Plastic is particularly useful for protecting cut and fill slopes and stockpiles. Note: The relatively rapid breakdown of most polyethylene sheeting makes it unsuitable for long-term (greater than six months} applications. • Clear plastic sheeting can be used over newly-seeded areas to create a greenhouse effect and encourage grass grow1h if the hydroseed was installed too late in the season to establish 75 percent grass cover, or if the wet season started earlier than normal. Clear plastic should not be used for this purpose during the summer months because the resulting high temperatures can kill the grass. • Due to rapid runoff caused by plastic sheeting, this method shall not be used upslope of areas that might be adversely impacted by concentrated runoff. Such areas include steep and/or unstable slopes. • Whenever plastic is used to protect slopes, water collection measures must be installed at the base of the slope. These measures include plastic-covered berms, channels, and pipes used to covey clean rainwater away from bare soil and disturbed areas. At no time is clean runoff from a plastic covered slope to be mixed with dirty runoff from a project. Plastic covering may also be used for: • Temporary ditch liner; • Pond liner in temporary sediment pond; • Liner for bermed temporary fuel storage area if plastic is not reactive to the type of fuel being stored; • Emergency slope protection during heavy rains; and, • Temporary drainpipe ("elephant trunk") used to direct water. Design and Installation Specifications: Plastic sheeting shall have a minimum thickness of 6 mils (0.006 inches, or 0.15 mm}. Plastic slope cover must be installed as follows: • Run plastic up and down slope, not across slope; • Plastic may be installed perpendicular to a slope if the slope length is less than 1 o feet; • Minimum of 8-inch overlap at seams; • On long or wide slopes, or slopes subject to wind, all seams should be taped; • Place plastic into a small (12-inch wide by 6-inch deep) slot trench at the top of the slope and backfill with soil to keep water from flowing underneath; • Place sand filled burlap or geotextile bags every 3 to 6 feet along seams and pound a wooden stake through each to hold them in place; • Inspect plastic for rips, tears, and open seams regularly and repair immediately. This prevents high velocity runoff from contacting bare soil which causes extreme erosion; • Sandbags may be lowered into place tied to ropes. However, all sandbags must be staked in place. • If erosion at the toe of a slope is likely, a gravel berm, riprap, or other suitable protection shall be installed at the toe of the slope in order to reduce the velocity of runoff. Maintenance Standards: • Torn sheets must be replaced and open seams repaired. • If the plastic begins to deteriorate due to ultraviolet radiation, it must be completely removed and replaced. • When the plastic is no longer needed, it shall be completely removed. ·- KING COUNTY SMALL PROJECT STORMWATER POLLUTION PREVENTION PLAN (SWPPP) 15219 149TH AVE SE, RENTON WA 98055 BMP C220: Storm Drain Inlet Protection +••P,0220+ Purpose: To prevent coarse sediment from entering drainage systems prior to permanent stabilization of the disturbed area. Conditions of Use: Where storm drain inlets are to be made operational before permanent stabilization of the disturbed drainage area. Protection should be provided for all storm drain inlets downslope and within 500 feet of a disturbed or construction area, unless the runoff that enters the catch basin will be conveyed to a sediment pond or trap. Inlet protection may be used anywhere to protect the drainage system. It is likely that the drainage system will still require cleaning. Design and Installation Specifications: Catchbasin filters Catch basin filters should be designed by the manufacturer for use at construction sites. The limited sediment storage capacity increases the amount of inspection and maintenance required, which may be daily for heavy sediment loads. The maintenance requirements can be reduced by combining a catchbasin filter with another type of inlet protection. This type of inlet protection provides flow bypass without overflow and therefore may be a better method for inlets located along active rights-of-way. 5 cubic feet of storage. Dewatering provisions. High-flow bypass that will not clog under normal use at a construction site. The catchbasin filter is inserted in the catch basin just below the grating. Maintenance Standards: Catch basin filters should be inspected frequently, especially after storm events. If the insert becomes clogged, it should be cleaned or replaced. For systems using stone filters: If the stone filter becomes clogged with sediment, the stones must be pulled away from the inlet and cleaned or replaced. Since cleaning of gravel at a construction site may be difficult, an alternative approach would be to use the clogged stone as fill and put fresh stone around the inlet. Do not wash sediment into storm drains while cleaning. Spread all excavated material evenly over the surrounding land area or stockpile and stabilize as appropriate. BMP C152: Sawcutting and Surfacing Pollution Prevention +••,,0102+ Purpose: Sawcutting and surfacing operations generate slurry and process water that contains fine particles and high pH (concrete cutting}, both of which can violate the water quality standards in the receiving water. This BMP is intended to minimize and eliminate · process water and slurry from entering waters of the State. Conditions of Use: Anytime sawcutting or surfacing operations take place, these management practices shall be utilized. Sawcutting and surfacing operations include, but are not limited to, the following: , Sawing • Coring • Grinding • Roughening • Hydro-demolition • Bridge and road surfacing Design and Installation Specifications: Slurry and cuttings shall be vacuumed during cutting and surfacing operations. Slurry and cuttings shall not remain on permanent concrete or asphalt pavement overnight. Slurry and cuttings shall not drain to any natural or constructed drainage conveyance. Collected slurry and cuttings shall be disposed of in a manner that does not violate groundwater or surface water quality standards. Process water that is generated during hydro-demolition, surface roughening or similar operations shall not drain to any natural or constructed drainage conveyance and shall be disposed of in a manner that does not violate groundwater or surface water quality standards. ~ .. ','•,,c., .. Cleaning waste material and demolition debris shall be handled and disposed of in a manner that does not cause contamination of water. If the area is swept with a pick-up sweeper, the material must be hauled out of the area to an appropriate disposal site. Maintenance Standards: Continually monitor operations to determine whether slurry, cuttings, or process water could enter waters of the state. If inspections show that a violation of water quality standards could occur, stop operations and immediately implement preventive measures such as berms, barriers, secondary containment, and vacuum trucks. The following narrative addresses the 12 SWPPP elements. 1 -PRESERVE VEGETATION/ MARK CLEARING LIMITS Puget Sound Energy's project limits will be delineated by construction cones when working on impervious surfaces. High visibility plastic fence(HVF) or silt fence will be used while working in soft surface areas. All areas required to be delineated will be marked prior to beginning of any land disturbing activities. All delineating HVF will be removed once construction in the area is complete. All construction activities consist of disturbing earth, to accommodate the installation of a · PSE Gas Pipe Facility by way of a trench. Absolutely no grading or clearing will be involved. All work will remain within hard surface roadway or roadway shoulder while with in the Right of Way. Work limits are determined by the approved Traffic Control Plans submitted with the King County Right of Way Permit. Sections of this work may proceed outside of the Right of Way, at which point all work limits will be defined with HVF. Absolutely no natural vegetation will be impacted during our construction. There are no Critical areas within our project limits. Best Management Practices (BMPs) to be used: • BMP C103: High Visibility Plastic Fence 2 -ESTABLISH CONSTRUCTION ACCESS Because this work remains in the roadway, and will be phased in lengths of 200' each day, there will not be the need to establish a specific construction access.

The Erosion control BMPs will be implemented in the following sequence: 1. Mark the project limits 2. Install protection for existing drainage systems and permanent drain inlets 4. Establish staging areas for storage and handling polluted materials and BM P's. 5. Install sediment control BM P's if necessary 6. Maintain BMPs until project is complete and site is stabilized, at which time they may be removed. PLEASE SEE CONSTRUCTION PLANS FOR SWPPP NOTES AND ALL LOCATIONS FOR BMPS TO BE UTILIZED. ALL BMP'S ARE INDICATED ON THE PLAN IN THE FOLLOWING SYMBOL +••~cio,. General SWPPP Notes: This project is covered under the small project SWPPP requirements. Construction Phasing will proceed day by day, limited to approximately 200 linear feet each day. All BM P's will be implemented at the beginning of the day prior to any construction activities. All BMP's will be removed at end of day after site is stabilized. Construction Crew will always make an effort to divert runoff away from exposed areas wherever possible. This SWPPP is NOT limited by the BM P's illustrated in this drawing. A CESCL will always be available to advise a more appropriate or additional BM P's when necessary. All Stock Piles will be held within the project phasing for that day's work.
