PAPERWORK BURDEN DISCLOSURE NOTICE
Public reporting burden for this data collection is estimated to average 1.63 hours per response. The burden estimate includes the time for reviewing instructions,
searching existing data sources, gathering and maintaining the needed data, and completing and submitting the form. This collection is required to obtain or retain
benefits. You are not required to respond to this collection of information unless a valid OMB control number is displayed on this form. Send comments regarding the
accuracy of the burden estimate and any suggestions for reducing this burden to: Information Collections Management, Department of Homeland Security, Federal
Emergency Management Agency, 1800 South Bell Street, Arlington, VA 20598-3005, Paperwork Reduction Project (1660-0015). NOTE: Do not send your completed
form to this address.
This form may be completed by the property owner, property owner’s agent, licensed land surveyor, or registered professional engineer to support a request for a
Letter of Map Amendment (LOMA), Conditional Letter of Map Amendment (CLOMA), Letter of Map Revision Based on Fill (LOMR-F), or Conditional Letter of Map
Revision Based on Fill (CLOMR-F) for existing or proposed, single or multiple lots/structures. In order to process your request, all information on this form must be
completed in its entirety, unless stated as optional. Incomplete submissions will result in processing delays. Please check the item below that describes your request:
LOMA A letter from DHS-FEMA stating that an existing structure or parcel of land that has not been elevated
by fill (natural grade) would not be inundated by the base flood.
CLOMA A letter from DHS-FEMA stating that a proposed structure that is not to be elevated by fill (natural
grade) would not be inundated by the base flood if built as proposed.
LOMR-F A letter from DHS-FEMA stating that an existing structure or parcel of land that has been elevated by
fill would not be inundated by the base flood.
CLOMR-F
A letter from DHS-FEMA stating that a parcel of land or proposed structure that will be elevated by fill
would not be inundated by the base flood if fill is placed on the parcel as proposed or the structure is
built as proposed.
Fill is defined as material from any source (including the subject property) placed that raises the ground to or above the Base Flood Elevation (BFE). The common
construction practice of removing unsuitable existing material (topsoil) and backfilling with select structural material is not considered the placement of fill if the
practice does not alter the existing (natural grade) elevation, which is at or above the BFE. Fill that is placed before the date of the first National Flood Insurance
Program (NFIP) map showing the area in a Special Flood Hazard Area (SFHA) is considered natural grade.
Has fill been placed on your property to raise
ground that was previously below the BFE? Yes No If yes, when was fill placed? /
month/year
Will fill be placed on your property to raise
ground that is below the BFE? Yes* No If yes, when will fill be placed? 01/20 or thereafter

This form must be completed for requests involving the existing or proposed placement of fill (complete Section A) OR to provide acknowledgment of this request to
remove a property from the SFHA which was previously located within the regulatory floodway (complete Section B).
This form must be completed and signed by the official responsible for floodplain management in the community. The six-digit NFIP community number and the

Community Number: 530088 Property Name or Address: 1915 Maple Valley HWY, Renton, WA 98057
A. REQUESTS INVOLVING THE PLACEMENT OF FILL
As the community official responsible for floodplain management, I hereby acknowledge that we have received and reviewed this Letter of Map
Revision Based on Fill (LOMR-F) or Conditional LOMR-F request. Based upon the community's review, we find the completed or proposed project
meets or is designed to meet all of the community floodplain management requirements, including the requirement that no fill be placed in the
regulatory floodway, and that all necessary Federal, State, and local permits have been, or in the case of a Conditional LOMR-F, will be obtained.
For Conditional LOMR-F requests, the applicant has or will document Endangered Species Act (ESA) compliance to FEMA prior to issuance of the
Conditional LOMR-F determination. For LOMR-F requests, I acknowledge that compliance with Sections 9 and 10 of the ESA has been achieved
independently of FEMA’s process. Section 9 of the ESA prohibits anyone from “taking” or harming an endangered species. If an action might harm
an endangered species, a permit is required from U.S. Fish and Wildlife Service or National Marine Fisheries Service under Section 10 of the ESA.
For actions authorized, funded, or being carried out by Federal or State agencies, documentation from the agency showing its compliance with
Section 7(a)(2) of the ESA will be submitted. In addition, we have determined that the land and any existing or proposed structures to be removed
from the SFHA are or will be reasonably safe from flooding as defined in 44CFR 65.2(c), and that we have available upon request by DHS-FEMA, all
analyses and documentation used to make this determination. For LOMR-F requests, we understand that this request is being forwarded to DHS-
FEMA for a possible map revision.

NOTES TO USERS
This map is for use in ad ministering the Na tio nal Flood Insuran ce Pro gram. It doe snot necessarily identify all areas subje ct to floodin g, pa rticu larly fro m local drainagesources of small size. The community map repository should be consulted forpossible updated or addition al flood hazard in formation .
To obtain more detailed in formation in are as where Base Flood Elevations (BFEs)and/or floodways have been determined, users are encouraged to consult the FloodProfiles and Floodway Data and/or Su mmary of Stillw ate r Eleva tio ns tables con tainedwithin the Flood Insurance Study (FIS) Repo rt that a cco mp anie s th is FIRM. Usersshould be aware that BFEs shown on the FIRM represent rounde d w hole -footelevations. These BFEs are intende d for floo d in surance ra ting p urposes o nly a ndshould not be used as the sole source of flo od elevation in formation . Acco rd ingly,flood elevation data presente d in the FIS Re port sh ould b e utilize d in conjunction withthe FIRM for purposes of constru ctio n a nd/or floo dpla in ma nage me nt.
Coastal Base Flood Elevations shown on this map apply only landward of 0.0’North American Vertical Datum of 19 88 (NAVD 8 8). Users of th is FIRM sho uld b eaware that coastal flood eleva tio ns are also provided in th e Summary of Stillwa te rElevations table in the Flood Insuran ce Stud y R eport fo r this jurisdiction . Eleva tio nsshown in the Summary of Stillw ate r Ele va tions tab le should be used for constru ctio nand/or floodplain manageme nt p urposes whe n they are higher than the elevatio nsshown on this FIRM.
Boundaries of the floodways were computed at cross sections and interpolatedbetween cross sections. The flo odways were b ased o n hydra ulic co nsidera tio ns withregard to requirements of th e National Flo od In su rance Program. Flood way widthsand other pertinent floodwa y data a re provided in the Flood Insura nce Study Re portfor this jurisdiction.
Certain areas not in Special Flood Hazard Are as may b e pro tected by flood controlstructures. Refer to Section 2.4 "Flood Protection Measures" of the Flood InsuranceStudy Report for information on flood con trol structure s for this jurisd iction.
Provisionally Accredited Le vee Notes to Users: Check with yo ur localcommunity to obtain more information, such as th e estimated le vel of protectionprovided (which may exceed the 1-pe rcen t-an nual-ch ance level) an d Emerge ncyAction Plan, on the levee syste m(s) shown as providing protection fo r area s onthis panel. To maintain accreditation , the levee ow ner or co mmun ity is requiredto submit the data and documentation ne cessary to comply with Section 6 5.1 0 ofthe NFIP regulations by Nove mb er 0 1, 20 18. If the commu nity o r own er doesnot provide the necessary data a nd docu me nta tio n or if the da ta anddocumentation provided indica te the levee syste m d oes not comply withSection 65.10 requireme nts, FEMA will revise the flood hazard and riskinformation for this area to reflect de-accredita tio n of th e levee system. Tomitigate flood risk in residua l risk areas, prope rty own ers and residents areencouraged to consider flood in surance an d floodp roofing or o the r prote ctivemeasures. For more informa tion on flood insura nce, interested p arties shou ldvisit the FEMA Website a t http://www.fe ma .go v/na tio nal-floo d-insuran ce -program.
The projection used in the preparation of this map was Universal TransverseMercator (UTM) zone 10. The horizontal datum was NAD 83, GRS 1980spheroid. Differences in d atu m, sp heroid , proje ctio n o r UTM zone s used in theproduction of FIRMs for adjace nt jurisd ictions may result in slig ht positio naldifferences in map features across ju risdiction b ound aries. These d iffere nces do n otaffect the accuracy of this FIRM.
Flood elevations on this ma p are referenced to th e No rth American Ve rtica l Da tum o f1988.

Base Map information shown on the FIRM was derived from multip lesources. Base map files we re p ro vided in digital fo rma t by King County G IS, WADNR, WSDOT, and Pierce Co unty G IS. This information was compiled at scales of1:12,000 to 24,000 during the time period of 199 4-2012 .
The profile baselines depicted on this map represent the hydraulic modeling baselines that match the flood profiles in the FIS re port. As a result of imp ro ved to pograph ic data, the profile baseline, in some cases, may deviate significantly from the channel centerline or appear outside the SFHA.
Based on updated topogra phic in formation , this map refle cts more detailed an dup-to-date stream channel configurations and floodplain delineations thanthose shown on the previo us FIRM for this jurisdiction . As a re su lt, th e FloodProfiles and Floodway Data table s for multiple stre ams in the FloodInsurance Study Report (w hich co nta ins authoritative hydraulic da ta) may reflectstream channel distances th at differ fro m wha t is shown on the ma p. Also, the road to floodplain relationship s fo r unrevise d stre ams ma y differ fro m what isshown on previous maps.

The 1% annual chance flood (100-year flood), also known as the base flood, is the flood that hasa 1% chance of being equaled or exceeded in any given year. The Special Flood Hazard Area isthe area subject to flooding by the 1% annual chance flood. Areas of Special Flood Hazardinclude Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water-surfaceelevation of the 1% annual chance flood.
No Base Flood Elevations determined.

NOTES TO USERS
This map is for use in ad ministering the Na tio nal Flood Insuran ce Pro gram. It doe snot necessarily identify all areas subje ct to floodin g, pa rticu larly fro m local drainagesources of small size. The community map repository should be consulted forpossible updated or addition al flood hazard in formation .
To obtain more detailed in formation in are as where Base Flood Elevations (BFEs)and/or floodways have been determined, users are encouraged to consult the FloodProfiles and Floodway Data and/or Su mmary of Stillw ate r Eleva tio ns tables con tainedwithin the Flood Insurance Study (FIS) Repo rt that a cco mp anie s th is FIRM. Usersshould be aware that BFEs shown on the FIRM represent rounde d w hole -footelevations. These BFEs are intende d for floo d in surance ra ting p urposes o nly a ndshould not be used as the sole source of flo od elevation in formation . Acco rd ingly,flood elevation data presente d in the FIS Re port sh ould b e utilize d in conjunction withthe FIRM for purposes of constru ctio n a nd/or floo dpla in ma nage me nt.
Coastal Base Flood Elevations shown on this map apply only landward of 0.0’North American Vertical Datum of 19 88 (NAVD 8 8). Users of th is FIRM sho uld b eaware that coastal flood eleva tio ns are also provided in th e Summary of Stillwa te rElevations table in the Flood Insuran ce Stud y R eport fo r this jurisdiction . Eleva tio nsshown in the Summary of Stillw ate r Ele va tions tab le should be used for constru ctio nand/or floodplain manageme nt p urposes whe n they are higher than the elevatio nsshown on this FIRM.
Boundaries of the floodways were computed at cross sections and interpolatedbetween cross sections. The flo odways were b ased o n hydra ulic co nsidera tio ns withregard to requirements of th e National Flo od In su rance Program. Flood way widthsand other pertinent floodwa y data a re provided in the Flood Insura nce Study Re portfor this jurisdiction.
Certain areas not in Special Flood Hazard Are as may b e pro tected by flood controlstructures. Refer to Section 2.4 "Flood Protection Measures" of the Flood InsuranceStudy Report for information on flood con trol structure s for this jurisd iction.
Provisionally Accredited Le vee Notes to Users: Check with yo ur localcommunity to obtain more information, such as th e estimated le vel of protectionprovided (which may exceed the 1-pe rcen t-an nual-ch ance level) an d Emerge ncyAction Plan, on the levee syste m(s) shown as providing protection fo r area s onthis panel. To maintain accreditation , the levee ow ner or co mmun ity is requiredto submit the data and documentation ne cessary to comply with Section 6 5.1 0 ofthe NFIP regulations by Nove mb er 0 1, 20 18. If the commu nity o r own er doesnot provide the necessary data a nd docu me nta tio n or if the da ta anddocumentation provided indica te the levee syste m d oes not comply withSection 65.10 requireme nts, FEMA will revise the flood hazard and riskinformation for this area to reflect de-accredita tio n of th e levee system. Tomitigate flood risk in residua l risk areas, prope rty own ers and residents areencouraged to consider flood in surance an d floodp roofing or o the r prote ctivemeasures. For more informa tion on flood insura nce, interested p arties shou ldvisit the FEMA Website a t http://www.fe ma .go v/na tio nal-floo d-insuran ce -program.
The projection used in the preparation of this map was Universal TransverseMercator (UTM) zone 10. The horizontal datum was NAD 83, GRS 1980spheroid. Differences in d atu m, sp heroid , proje ctio n o r UTM zone s used in theproduction of FIRMs for adjace nt jurisd ictions may result in slig ht positio naldifferences in map features across ju risdiction b ound aries. These d iffere nces do n otaffect the accuracy of this FIRM.
Flood elevations on this ma p are referenced to th e No rth American Ve rtica l Da tum o f1988. These flood elevations mu st be compared to structure and groun d ele vationsreferenced to the same vertical datum.

Base Map information shown on the FIRM was derived from multip lesources. Base map files we re p ro vided in digital fo rma t by King County G IS, WADNR, WSDOT, and Pierce Co unty G IS. This information was compiled at scales of1:12,000 to 24,000 during the time period of 199 4-2012 .
The profile baselines depicted on this map represent the hydraulic modeling baselines that match the flood profiles in the FIS re port. As a result of imp ro ved to pograph ic data, the profile baseline, in some cases, may deviate significantly from the channel centerline or appear outside the SFHA.
Based on updated topogra phic in formation , this map refle cts more detailed an dup-to-date stream channel configurations and floodplain delineations thanthose shown on the previo us FIRM for this jurisdiction . As a re su lt, th e FloodProfiles and Floodway Data table s for multiple stre ams in the FloodInsurance Study Report (w hich co nta ins authoritative hydraulic da ta) may reflectstream channel distances th at differ fro m wha t is shown on the ma p. Also, the road to floodplain relationship s fo r unrevise d stre ams ma y differ fro m what isshown on previous maps.
Corporate limits shown on this map are based on the best data available at the timeof publication. Because cha nges d ue to ann exations or d e-anne xa tions may haveoccurred after this map w as p ublish ed, map use rs should contact app ro priatecommunity officials to verify current corpo rate limit loca tio ns.

The 1% annual chance flood (100-year flood), also known as the base flood, is the flood that hasa 1% chance of being equaled or exceeded in any given year. The Special Flood Hazard Area isthe area subject to flooding by the 1% annual chance flood. Areas of Special Flood Hazardinclude Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water-surfaceelevation of the 1% annual chance flood.
No Base Flood Elevations determined.

In 2008, the National Marine Fisheries Service (NMFS) issued a Biological Opinion, which
found that the implementation of the National Flood Insurance Program (NFIP) in the
Puget Sound region jeopardized the continued existence of federally threatened salmonids
and resident killer whales. As a result, NMFS established Reasonable and Prudent
Alternatives to ensure that development within the Special Flood Hazard Area (100-year
floodplain), floodway, Channel Migration Zone (CMZ), and riparian buffer zone do not
adversely affect water quality, flood volumes, flood velocities, spawning substrate, or
floodplain refugia for listed salmonids. Because the NFIP is implemented by FEMA
through participation by local jurisdictions that adopt and enforce floodplain management
ordinances, FEMA has delegated responsibility to the local jurisdictions to ensure that
development does not adversely affect listed species.
To that end, RMC 4-8-120D.2 requires preparation of a biological assessment/critical areas
study for projects with the potential to impact fish (Chinook salmon, bull trout, steelhead
trout), unexpected, new, rare or other endangered species habitat (bald eagles). This report
evaluates the likely effects of proposed alterations within the floodplain, riparian buffer
zone, and channel migration zone and finds that the project is not likely to adversely affect
threatened salmonids or critical habitat.
The project does not have a federal nexus; therefore, consultation with NMFS and US Fish
and Wildlife Service is not required under Section 7 of the Endangered Species Act (ESA).
The project, as proposed, will not result in “take” of listed species; therefore, Section 9 of the
ESA does not apply.
2. Site Description
2.1 Project Location
The proposed project is located at 1915 Maple Valley Highway (parcel 1723059026) in the
incorporated area of the City of Renton, Washington (Figure 1). The project area is located
just southeast of where the Maple Valley Highway crosses beneath Interstate 405 in Section
17, Township 23 North, Range 5 East. It lies within the Lower Cedar River Drainage Basin
or the Cedar-Sammamish Watershed Resource Inventory Area (WRIA 8). The property is
bordered to the west by Cedar River Park, to the east by a developed commercial parcel, to
the north by Maple Valley Highway, and to the south by the Cedar River. Across the Maple
Valley Highway from the parcel is an undeveloped, forested HOA open space tract.
Another undeveloped, forested parcel, owned by the City of Renton, is present along the
southern bank of the Cedar River across from the project area.

2.2 Flood Features
The Special Flood Hazard Area (100-year floodplain) of the Cedar River includes the
southern portion of the project area extending up to approximately 150 feet landward from
the OHWM (See Figure 2 and site plan). The most conservative 100-yr flood profile was
determined based on a comparison of the FEMA Effective FIRM (FEMA 1995), preliminary
DFIRM (FEMA 2013), and output results from the updated HEC-RAS based model
(containing the latest available LiDAR data) as received from King County River and Flood
District. The most conservative (highest) floodplain values came from the preliminary
DFIRM, which was used as the basis for the floodplain delineation. A horizontal projection
of the 100-year flood boundary was delineated by intersecting the site topography surface
and the flood water surface using a digital surface created in Civil 3D based on topographic
contours from the site survey from D.R. Strong Consulting Engineers Inc., dated August 16,
2017.
The mapped floodway is generally consistent with the delineated OHWM, except in the
western portion of the site, where the floodway extends approximately 35 feet landward
from the OHWM. Aside from the Cedar River, no other streams or wetlands are present in
the project area.
King County maps the entire parcel as within the severe CMZ hazard area (King County
2015). This classification is based on the historic river channel, which occupied the parcel
location. Per the King County methodology, any area within the historical migration one
was mapped as severe hazard area, and privately maintained structures were not
considered as potential limits to migration. Today, shoreline stabilization in the eastern half
of the project area limits potential channel migration into the site.
The Riparian Buffer Zone (RBZ), designated by the National Marine Fisheries Service
(NMFS), extends 250 feet landward from the OHWM. Within the boundaries of RBZ, the
100 feet landward from the OHWM is regulated as a stream buffer under the Renton
Critical Areas Regulations.

2.3 Environmental Setting
The baseline conditions that in the Lake Washington watershed are described in Salmon and
Steelhead Habitat Limiting Factors Report for WRIA 8 (Kerwin 2001); and the Lake
Washington/Cedar/Sammamish Watershed (WRIA 8) Chinook Salmon Conservation Plan (WRIA 8
2005). The following discussion describes the relevant site-specific baseline conditions, in
particular focusing on those items that are unique about the site.
Site visits were conducted in May, September and March of 2017 to evaluate the existing
conditions of the site. Assessments conducted included a tree inventory, wetland
reconnaissance, and delineation of the ordinary high water mark (OHWM) of the Cedar
River. Public-domain information on the subject property was reviewed. These sources
include USDA Natural Resources Conservation Service Soil maps, U.S. Fish and Wildlife
Service National Wetland Inventory maps, Washington Department of Fish and Wildlife
interactive mapping programs (PHS on the Web and SalmonScape), COR Maps, and King
County’s GIS mapping website (iMAP).
The project parcel was historically used as a concrete facility. Although industrial facilities
have been removed from the site, a constructed settling pond is present along the Cedar
River shoreline. This pond was used for settling of concrete was water. Today, it is
separated from the Cedar River by a concrete wall. The settlement pond is filled with water
with a distinct color difference from the Cedar River, indicating that there is no transfer of
water between the settlement pond and the river.
A concrete bulkhead extends east from the settling pond, forming the ordinary high water
mark (OHWM) of the Cedar River. To the west of the settling pond, the shoreline bank
slopes gradually, and a retaining wall is located well landward of the OHWM. A chain link
fence sits on top of the concrete wall and retaining wall along the length of the shoreline
property
The lot in its current condition is almost entirely cleared with a gravel and/or compacted
dirt base. Tree and shrub species are mainly limited to the edges of the parcel. Fifty three
individual trees were inventoried within the parcel. Tree species present are primarily red
alder, black cottonwood and big leaf maple.
The Cedar River is located to the south of the subject parcel. The water surface elevation of
the Cedar River is influenced by operations at the Masonry Dam and the Landsburg
Diversion Dam upstream in the Cedar River. Together, the dams are managed for water
supply to the Seattle metropolitan area; to ensure base flows necessary to support instream
uses, including fish habitat; for hydroelectric power; and for flood control. Along the parcel,
the Cedar River flows as a glide or riffle along the length of the parcel, depending on the
season. A large pool is present at the eastern extent of the parcel.

No wetlands or streams, other than the Cedar River, are present on site. However, several
other features classified as critical areas by the City of Renton have been
3. Species Identification and Site Use
Three salmonid species are listed as threatened under the ESA in the Puget Sound area.
These species include Chinook salmon (Oncorhynchus tshawytscha) of the Puget Sound
Distinct Population Segment (DPS), steelhead (O. mykiss) of the Puget Sound DPS, and bull
trout (Salvelinus confluentus). The project reach is used as a migration corridor for all of the
species listed above and may be used for spawning and rearing by Chinook salmon and
steelhead. The Cedar River, including the project reach, is designated as Critical Habitat for
all three species.
3.1 Chinook Salmon
In the Lake Washington watershed, Chinook salmon are broken into two stocks: 1) the
Cedar River, and 2) the Sammamish River (City of Seattle 2008). The majority of
summer/fall-run Chinook salmon migrate through the Lake Washington ship canal to reach
spawning habitat in either the Cedar or Sammamish River systems, while a smaller
proportion of Chinook salmon spawn in other Lake Washington tributaries. The Lake
Washington basin has seen an average escapement of 1,214 returning Cedar Chinook
salmon and 1,269 returning Sammamish Chinook salmon from 2004 to 2015 (WDFW
SCORE electronic reference).
The Watershed Company
October 2018

Adults migrate into freshwater in late July through early September and spawn in the
tributaries to Lake Washington between August and November (City of Seattle 2008).
Graphs of trapping data indicate that juvenile Chinook salmon migrating from the
tributaries into Lake Washington exhibit two basic strategies: 1) direct migration to the lake
as fry without extended stream rearing; and 2) migration to the lake as parr or smolts
(average length 100 mm), following extended stream rearing. Chinook fry begin entering
Lake Washington around the first of the year, peaking in February, while parr and smolts
enter the lake from April through July, peaking in late May (Tabor et al. 2006).
Chinook salmon may use the project reach for spawning, rearing and migration. In
particular, a deep pool near the eastern edge of the parcel may be used for holding during
upstream migrations.
3.2 Steelhead
Steelhead are currently present in the watershed. The Cedar River and South Lake
Washington Winter steelhead are identified as a discrete stock within the Puget Sound
steelhead DPS. These steelhead are characterized as a native stock with wild production.
Historic steelhead escapement for the Lake Washington basin was estimated at 1,816 in
1986 and has steadily declined since that time. In 2002 their stock status was adjusted
downward from “depressed” to “critical” due to chronically low escapements and severe
short-term declines in escapement in 2000 and 2001. The Cedar River saw an average
escapement of 11 returning steelhead from 2004 to 2015, with zero fish returning in 2009,
2012, and 2014 (WDFW SCORE electronic reference).
Steelhead are documented to have spawned historically in many Lake Washington and
Lake Sammamish tributaries. Adult steelhead may pass through the ship canal from
February through June (City of Seattle 2008). The steelhead spawning period in the Lake
Washington basin currently extends from March to September (City of Seattle 2008), with
most adult fish in the run typically returning to the Cedar River. Both anadromous
(steelhead) and resident (rainbow trout) life forms of O. mykiss (based on life history
characteristics) are likely present in the Lake Washington basin.
Juveniles generally emigrate as smolts between April and June, after two years of stream
residence. However, the duration of freshwater rearing can range from one to seven years
before juveniles grow large enough (>170 mm) to undergo smoltification. Steelhead exhibit
a highly variable anadromous life history. Steelhead in the Lake Washington basin are
winter run fish, characteristic of coastal streams. They enter freshwater from November to
April and spawn shortly thereafter (Busby et al. 1996). Summer surface temperatures in the
Lake Washington system often exceed the thermal preferences of most salmonids, including
steelhead.
8
3.3 Bull Trout
Native char are not commonly observed within the Lake Washington Watershed. Bull trout
are observed at the Ballard Locks every year with numbers observed or caught varying
from three to nine fish per year (F. Goetz, pers. comm., 14 May 2004). They are
observed/caught at the Locks between May and July (note: little or no monitoring occurs at
the Locks from February through April, so data are not available for that period).
Bull trout are sensitive to high water temperatures, and would not be expected within river
reaches when temperatures exceed 15˚C (generally, from May through mid-October).
Juvenile bull trout remain in headwater streams until the onset of piscivory, at a body
length of approximately 300 mm, at which point they migrate as subadults in search of
improved foraging opportunities. Subadult bull trout often migrate with adults to
headwater streams during the summer and fall, and return to larger rivers to overwinter.
Bull trout may be attracted to spawning aggregations of prey fish. Many native char in
populations from north Puget Sound exhibit anadromy, migrating to marine waters in late
winter (F. Goetz, pers. comm., 14 May 2004).
3.4 Other Species
According to U.S. Fish and Wildlife Service’s Information for Planning and Conservation,
other threatened or endangered species that should be addressed in the project area include
marbled murrelet (Brachyramphus marmoratus), streaked horned lark (Eremophila alpestris
strigata), and yellow-billed cuckoo (Coccyzus americanus). None of these species have been
documented in the project area per PHS Data. Furthermore, there is no suitable habitat for
any of these species in the project vicinity. Nesting marbled murrelets require old-
growth/mature coniferous forests in dense coastal stands; yellow-billed cuckoos require
large, continuous riparian corridors populated by dense willow and cottonwood forests;
and streaked horned larks require open grasslands, prairies, herbaceous balds, or sandy
islands. None of these habitats is present in the project vicinity. Therefore, the proposed
project will have no effect on marbled murrelets, yellow-billed cuckoos, or streaked
horned larks.
No other endangered, threatened, sensitive, or priority species are documented by PHS
Data for the property. No such species were observed during site inspections, and no
additional critical wildlife habitat is present.
4. Project Description
The proposal includes development of a residential, multifamily apartment complex, a
commercial development pad, shoreline buffer restoration and public access improvements
on a 546,121 SF lot adjacent to the Cedar River.
The Watershed Company
October 2018
9
All development is proposed outside of the shoreline buffer and Cedar River habitat
conservation area, with exception of a public access trail and associated public access areas
along the shoreline, provided in compliance with the City’s public access requirements. The
remainder of the buffer will be restored with native plantings, which will provide a net
improvement over the existing condition and provide screening between the upland
development and the river. The floodplain area will be graded to result in a net increase in
floodplain storage capacity. No fill will occur within the floodway.
5. Conservation Measures
The project avoids and minimizes potential effects to listed species through the following
measures:
• Avoidance- No in-water work will be conducted.
• Avoidance- The City’s standard 100-foot buffer and 15-foot setback will be followed.
• Minimization- Best management practices will be employed, including but not
limited to covering all exposed soils not worked within seven days and employing
all erosion control measures within jurisdictional standards.
• Minimization- Any construction debris and/or excavated materials will be removed
and disposed of off-site.
• Minimization- Compensatory storage will be provided for floodplain fill, such that
there will be no net loss of floodplain storage.
6. Project Effects
Potential direct and indirect effects of the project on listed salmonids include effects to
water quality, flood storage and conveyance, habitat quality, and prey availability. Each of
these potential effects are described below.
6.1 Water Quality
No in-water work is proposed, which significantly minimizes potential effects to listed fish
species. Proposed grading within the riparian zone does present the potential to affect
water quality in the Cedar River. In order to avoid and minimize any effects to water
quality, the project will implement a temporary erosion and sediment control plan and a
stormwater construction pollution prevention plan. These plans will ensure that measures
are in place to control erosion and prevent spills that could affect water quality. Any
accidental spills of toxic substances will be contained on the site and appropriately treated
and disposed of immediately upon discovery.
In the long-term, the proposed project will generate runoff from both pollutant and non-
pollutant generating surfaces. Urban stormwater, which may include sediments, heavy
10
metals, polycyclic aromatic hydrocarbons (PAHs), pesticides, and nutrients can enter
waterbodies through bank erosion, road run-off, landslides, or overland flow. Stormwater
generated through impervious surfaces with vehicular use can disrupt salmonid
physiology and behavior, and is a significant water quality concern for salmonids
(McCarthy et al. 2008; Spromberg and Scholz 2011). All stormwater from pollutant-
generating surfaces (at-grade parking and open-air parking garage) will be routed to a two-
facility treatment train, including a wet vault and a Contech StormFilter system, recognized
as a General Use Level Designation (GULD) for basic treatment. The treatment system will
be sized to treat 91% or more of the total runoff volume. Following treatment, stormwater
will be conveyed through a pipe to the southeastern side of the building. Stormwater from
non-pollutant generating surfaces (building roofs) will be collected and routed separately
from the pollutant-generating surfaces on the southwest side of the building. The two
separate stormwater pipes will outfall in the buffer into a lined vegetated swale. The swale
will provide additional biofiltration prior to reaching the Cedar River. As a result of
treatment and biofiltration within the buffer, effects to water quality within the Cedar River
are expected to be insignificant.Flood Storage and Conveyance
In a riverine setting, temporary storage of floodwaters can help reduce downstream flood
heights and dissipate much of the energy of flood flows (Gregory et al. 1987). The proposed
project will increase floodplain storage capacity as a result of net cut within the floodplain.
6.2 Habitat Quality
The project will result in an improvement in floodplain functions through revegetation of
the 100-foot buffer are with native trees, shrubs, and groundcover and restoration of
floodplain connectivity. As it matures over time, this vegetation will support detritus,
woody debris, and invertebrates, which provide a prey source for juvenile salmon. Restored
floodplain areas will provide improved access to off-channel areas for rearing juvenile
salmon during high flows. This is particularly valuable given the limited off-channel
opportunities downstream from the project site.
The project will not alter existing bank stabilization measures. Therefore, the project will
not affect channel migration or bank stability.
The proposed project will increase impervious surfaces within the 250-foot RBZ, as
described by NMFS (2008). Potential effects from the development could arise from
pollutants (see water quality above), effects to water quantity (see flood storage and
conveyance above), and disturbance. Disturbance would be most likely to result from
effects from lighting. The proposed project will avoid and minimize potential disturbance
through the vegetated buffer, which will separate the development from the river, and
through the use of downcast outdoor lighting, which will prevent glare from reaching the
river.

7. Critical Habitat
Critical habitat includes areas with physical or biological features essential to the
conservation of the species and which may require special management considerations or
protection.
7.1 Chinook Salmon and Steelhead
Primary constituent elements of Puget Sound Chinook salmon and Puget Sound steelhead
critical habitat are listed as:
1. Freshwater spawning sites with water quantity and quality conditions and
substrate supporting spawning, incubation and larval development.
2. Freshwater rearing sites with water quantity and floodplain connectivity to
form and maintain physical habitat conditions and support juvenile growth
and mobility; water quality and forage supporting juvenile development;
and natural cover such as shade, submerged and overhanging large wood,
log jams and beaver dams, aquatic vegetation, large rocks and boulders, side
channels, and undercut banks.
3. Freshwater migration corridors free of obstruction with water quantity and
quality conditions and natural cover such as submerged and overhanging
large wood, aquatic vegetation, large rocks and boulders, side channels, and
undercut banks supporting juvenile and adult mobility and survival.
4. Estuarine areas free of obstruction with water quality, water quantity, and
salinity conditions supporting juvenile and adult physiological transitions
between fresh- and saltwater; natural cover such as submerged and
overhanging large wood, aquatic vegetation, large rocks and boulders, and
side channels; and juvenile and adult forage, including aquatic invertebrates
and fishes, supporting growth and maturation.
5. Nearshore marine areas free of obstruction with water quality and quantity
conditions and forage, including aquatic invertebrates and fishes, supporting
growth and maturation; and natural cover such as submerged and
overhanging large wood, aquatic vegetation, large rocks and boulders, and
side channels.
6. Offshore marine areas with water quality conditions and forage, including
aquatic invertebrates and fishes, supporting growth and maturation.
Project activities that introduce or remove physical elements to and/or from the French
Creek drainage, or that contribute to short-term changes in water quality, may alter certain
primary constituent elements (Table 1).
12
Table 1. Assessment of primary constituent elements for Chinook salmon and steelhead.
Primary Constituent
Element
Direct, Indirect, Interrelated and Interdependent Effects
1. Freshwater spawning By increasing floodplain storage capacity, the project will not increase
flood flows downstream. Therefore the project will not contribute to
increased scour of downstream redds.
2. Freshwater rearing By increasing floodplain storage capacity, the project will not increase
flood flows downstream. The project will restore native vegetation
within the area within 100 feet of the OHWM, which will support
rearing habitat along the bank, as well as detritus and insect
production. The project will increase accessible floodplain habitat for
juvenile Chinook salmon and steelhead. It will result in an increase in
impervious surface area within the RBZ, but all stormwater from
pollutant-generating surfaces (at-grade parking and open-air parking
garage) will be routed to a two-facility treatment train, followed by a
vegetated drainage pathway within the buffer. As a result of
treatment and biofiltration within the buffer, effects to water quality
within the Cedar River are expected to be insignificant.
3. Freshwater migration By increasing floodplain storage capacity, the project will not increase
flood flows downstream. The project will restore native vegetation
within the area within 100 feet of the OHWM, which will support
holding areas during migration. The project will increase accessible
floodplain habitat which may be used as a holding area during
upstream or downstream migrations. It will result in an increase in
impervious surface area within the RBZ, but all stormwater from
pollutant-generating surfaces (at-grade parking and open-air parking
garage) will be routed to a two-facility treatment train, followed by a
vegetated drainage pathway within the buffer. As a result of
treatment and biofiltration within the buffer, effects to water quality
within the Cedar River are expected to be insignificant.
4. Estuarine areas The project would have no effect on estuarine areas.
5. Nearshore marine areas The project would have no effect on nearshore marine areas.
6. Offshore marine areas The project would have no effect on offshore marine areas.
7.2 Bull Trout
The primary constituent elements of bull trout critical habitat area listed below.
1. Springs, seeps, groundwater sources, and subsurface water connectivity
(hyporheic flows) to contribute to water quality and quantity and provide
thermal refugia.
2. Migration habitats with minimal physical, biological, or water quality
impediments between spawning, rearing, overwintering, and freshwater and
marine foraging habitats, including but not limited to permanent, partial,
intermittent, or seasonal barriers.
3. An abundant food base, including terrestrial organisms of riparian origin,
aquatic macroinvertebrates, and forage fish.
The Watershed Company
October 2018

4. Complex river, stream, lake, reservoir, and marine shoreline aquatic
environments, and processes that establish and maintain these aquatic
environments, with features such as large wood, side channels, pools,
undercut banks and unembedded substrates, to provide a variety of depths,
gradients, velocities, and structure.
5. Water temperatures ranging from 2 to 15 degrees Celsius (°C) (36 to 59
degrees Fahrenheit (°F)), with adequate thermal refugia available for
temperatures that exceed the upper end of this range. Specific temperatures
within this range will depend on bull trout life-history stage and form;
geography; elevation; diurnal and seasonal variation; shading, such as that
provided by riparian habitat; streamflow; and local groundwater influence.
6. In spawning and rearing areas, substrate of sufficient amount, size, and
composition to ensure success of egg and embryo overwinter survival, fry
emergence, and young-of-the-year and juvenile survival. A minimal amount
of fine sediment, generally ranging in size from silt to coarse sand,
embedded in larger substrates, is characteristic of these conditions. The size
and amounts of fine sediment suitable to bull trout will likely vary from
system to system.
7. A natural hydrograph, including peak, high, low, and base flows within
historic and seasonal ranges or, if flows are controlled, minimal flow
departure from a natural hydrograph.
8. Sufficient water quality and quantity such that normal reproduction, growth,
and survival are not inhibited.
9. Sufficiently low levels of occurrence of nonnative predatory (e.g., lake trout,
walleye, northern pike, smallmouth bass); interbreeding (e.g., brook trout);
or competing (e.g., brown trout) species that, if present, are adequately
temporally and spatially isolated from bull trout.
Potential effects to bull trout critical habitat are limited, as described in Table 2.

14
Primary Constituent
Element
Direct, Indirect, Interrelated and Interdependent Effects
Water temperature The project will support shading of the Cedar River through the
revegetation of a 100-foot wide riparian buffer area. This will
support cooler water temperatures for bull trout. .
Spawning substrate The project will not affect spawning substrate. By balancing cut
and fill, the project increases floodplain storage and conveyance
capacity such that it may reduce scour caused by high flows during
floods.
Natural hydrograph The project will support the natural hydrograph by increasing
floodplain storage and conveyance capacity.
Sufficient water quality and
quantity
Water quality will be protected during construction through the
use of best management practices and implementation of a
temporary erosion and sediment control plan and a stormwater
pollution protection plan. In the long-term, effects on water quality
from treated and biofiltered stormwater will be insignificant.
Water quantity will be maintained through no net fill of the
floodplain.
Predation The project will have no effect on predation on bull trout.
8. Cumulative Effects
Cumulative effects entail the effects of future private, state, or federal activities that are
reasonably certain to occur. The project area is located within the City of Renton and King
County, Washington, an area that is experiencing rapid population growth. Significant
demand for additional residential development has accompanied this population growth.
Therefore, the area surrounding the project is expected to continue to urbanize and
redevelop. Increasingly strict local, state, and federal regulations suggest that despite an
increasing intensity of land use, redevelopment is likely to result in improvements in
stormwater management and riparian and floodplain restoration.
9. Summary
In summary, because potential adverse effects of the project related to water quality are
insignificant, because the project will maintain flood storage and conveyance, and because
the project will restore floodplain habitat functions within the 100-foot riparian zone, the
project may affect, but is not likely to adversely affect listed salmonids. Similarly, given the
direct, indirect, interrelated, and interdependent effects from the proposed action, the
proposed project may affect, but is not likely to adversely affect critical habitat of Puget
Sound Chinook salmon, Puget Sound steelhead, or Coastal-Puget Sound bull trout.
