Report of September 12, 2016 Page 2 of 4 I PART ONE; PROJECT DESCRIPTION/ BACKGROUND The applicant's proposal is in response to Code Compliance Case 15-000489 that was opened August 7, 2015 for unpermitted encroachments into a Type Ns (non-fish) stream in the rear yard of an existing single-family residence. Specifically, the property owner installed approximately 27 linear feet of streambank armoring consisting of concrete masonry unit (CMU) blocks below the ordinary high water mark (OHWM) without prior approvals. To resolve the referenced compliance case, the applicant proposes to remove the 52 CMU blocks that comprise the unpermitted encroachments and regrade the slope. Following removal of the blocks, erosion control measures including a coir log wattle will be placed at the OHWM of the stream to minimize erosion while vegetation becomes established. A riparian restoration seed mix will be spread along the regraded portion of the stream bank for long term bank stabilization and bank restoration. Concrete rip-rap is located along portions of the stream bank upstream of the restoration area and within the subject property boundaries. Placement of this rip-rap was installed prior to the current ownership, and as provided in the stream report, likely several decades previous. Removal of the previous rip-rap armoring is not proposed in this restoration plan and was not a requirement of the code compliance case.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The proposed CMU block removal will disturb approximately 60 square feet of area on and around the OHWM. Removal of the block wall will result in a slope that is nearly vertical and susceptible to further stream incising and conditions that are not conducive to revegetation. The submitted stream study and biological assessment recommends installing a coir log along the base of the wall while removing the blocks for temporary erosion and sedimentation control. The submitted stream study and biological assessment recommends excavation of the bank to a slope of approximately two (2) feet horizontal to one (1) foot vertical to provide the appropriate grade contour for the proposed restoration seed mix plantings to germinate. Block removal and restoration should occur during extended dry periods to reduce potential erosion and incising of the exposed bank. Staff recommends as SEPA mitigation measures that project construction be required to comply with recommendations of the July 28, 2016 Standard Stream Study and Biological Assessment prepared by 7K Environmental (Exhibit 2) and the block removal/restoration activities be completed no later than August 1, 2017. Mitigation Measures: 1. The applicant shall follow the recommendations of the July 28, 2016 Standard Stream Study and Biological Assessment prepared by 7K Environmental. 2. The applicant shall remove the unpermitted block wall and install the restoration following approvals from other applicable agencies and no later than August 1, 2017. Nexus: City of Renton Comprehensive Plan Goal L-P: Minimize adverse impacts to natural systems, and address impacts of past practice where feasible, through leadership, policy, regulation, and regional coordination. City of Renton Comprehensive Pion Policy L-29: Minimize erosion and sedimentation in and near sensitive areas by requiring appropriate construction techniques and resource practices, such as low impact development. City of Renton Comprehensive Pion Policy L-30: Protect the integrity of natural drainage systems, existing land forms, and maintain wildlife habitat values by preserving and enhancing existing vegetation and tree canopy coverage to the maximum extent possible and by restoring hydrological flows and improving the condition of shorelines. 2. Water a. Wetland, Streams, Lakes Impacts: Restoration work will occur below and around the OHWM of the stream located on the northeast portion of the subject property. The stream bed is within a swale approximately six (6) to eight (8) feet below the surrounding topography. The stream is approximately two (2) feet wide at ERC REPORT 16-000307 City of Renton Department of Community anomic Development nvironmental Review Committee Report TRAN WALL REMOVAL & STREAMBANK RESTORATIONERRORI REFERENCE SOURCE NOT FOUND. LUA16-000307,ECF,CAEERROR! REFERENCE SOURCE NOT FOUND. Report of September 12, 2016 Page 4 of 4 the OHWM along the reach of channel on the subject property. The stream is a tributary to May Creek approximately 700-feet northwest of the site and has been classified as a non-fish bearing watercourse or Type Ns. Removal of the block wall and restoration of the bank will improve hydrology prior to existing conditions as unarmored streambanks tend to reduce stream flow velocities thereby reducing the potential for erosion and turbid waters. Other potential lift for ecosystem functions include: (1) increased biogeochemical functioning by allowing the stream to have direct contact with the soil instead of the block wall; (2) new riparian plantings along the bank will contribute to diverse plant community functions; and (3) increase in habitat functions for aquatic and terrestrial invertebrates and small invertebrates by creating greater connectivity between upland and the stream. As mentioned above under 1. Earth, the submitted stream study and biological assessment recommends restoration work that includes removing the block wall, re-grading the bank, and installing erosion control and riparian vegetation. This work should occur during extended dry periods to reduce erosion and turbidity. Staff recommends as SEPA mitigation measures that project construction be required to comply with recommendations of the Standard Stream Study and Biological Assessment prepared by 7K Environmental (dated July 28, 2016) and the block removal/restoration activities be completed no later than August 1, 2017. Mitigation Measures: 1. Applicant shall follow the recommendations of the July 28, 2016 Standard Stream Study and Biological Assessment prepared by 7K Environmental. 2. Applicant shall remove the unpermitted block wall and install the restoration following approvals from other applicable agencies and no later than August 1, 2017. Nexus: City of Renton Comprehensive Plan Goal L-U: Preserve, protect, and enhance the quality and functions of the City's sensitive areas including: lakes, rivers, major and minor creeks, intermittent stream courses and their floodplains, wetlands, ground water resources, wildlife habitats, and areas of seismic and geological hazards. City of Renton Comprehensive Plan Policy L-32: Protect buffers along wetlands and surface waters to facilitate infiltration and maintain stable water temperatures, provide for biological diversity, reduce amount and velocity of run-off, and provide for wildlife habitat.

ERC REPORT 16-000307 7K Environmental Kate Knox Machata 7K Environmental 4062 NE 87'h St. Seattle, WA 98115 Matt Herrera Planning Division, Community & Economic Development City of Renton 1055 South Grady Way Renton, WA 98057 July 28, 2016 RE: Stream Bank Restoration Project Application for Alyssa and Tony Tran (Parcel number 334210-3365}: Standard Stream Study and Biological Assessment Dear Mr. Herrera: With this letter report, we are requesting SEPA review and critical areas permit approval from the City of Renton for the proposed stream bank restoration project in parcel 334210-3365. Additional materials are attached to meet permit submittal requirements as indicated on the Exemption from Critical Areas Regulations checklist. Project Introduction In August 2015, 7K Environmental was contracted to assist Alyssa Tran and Tony Ly with permit preparation for buffer enhancement plantings the stream buffer adjacent to their home. This permit was issued and planting occurred in November 2015 {LUA15-000761). In conjunction with this permit, the City is requiring that the homeowner remove 27 linear feet of concrete block retaining wall that was placed without permit along the northeast (a.k.a. river right) stream bank. The stream bank will be restored to prior condition and planted with native herbaceous vegetation to match site condition prior to wall installation in this reach. This report has been prepared to describe existing conditions on the site, discuss existing ecological functions in the stream buffer, and provide details of the proposed stream restoration activities along the unnamed stream that crosses their property. This letter report is designed to serve as the Standard Stream Study and Biological Assessment per Renton Municipal Code {RMC) 4-8-120D. 1 Project Site Description and Landscape Position The Tran property (Parcel number 334210-3365) is located at 2816 Kennewick Place NE in the City of Renton (see Figure 1 provided by City of Kent and Sheet 1). This parcel lies approximately 600 feet east of 1-405 in the developed urban neighborhood of Kennydale. A small, unnamed tributary of May Creek (See Figure 1) with an ordinary high water (OHW) width of approximately 2 feet lies near the northeast edge of the Tran property. No wetlands were observed on the property or adjacent to the property boundary as far as was visible from the Tran property. The unnamed tributary has a small watershed (estimated to be about 40 acres in size) upstream from the subject parcel. Approximately 80 feet upstream from the parcel, the stream is impounded by a 2-3 foot high concrete dam. A culvert carries water west under NE 29 1 • Street. The stream conveys water approximately 700 feet north and west to its confluence with May Creek which joins Lake Washington approximately one mile further north and west. May Creek is known to be a fish bearing stream with documented presence with possible spawning for fall Chinook and coho salmon and winter run steel head. No fish presence has been noted in the unnamed tributary on the Tran property (SalmonScape 2015). Site History The Tran/Ly family purchased the subject parcel in 2011. The existing dilapidated structure was demolished in 2012, and site grading was completed to allow for construction of a new residence under the new single family residence combination permit number CP12039. Final landscape elements were installed in 2012. Existing uses in the vicinity of the channel prior to 2012 included a home with landscaped yard including a swimming pool, fence, and retaining wall which paralleled the channel, approximately 15 feet to the south. Based on aerial photography analysis, the land was cleared and roads were constructed along the current path of Kennewick Road and NE 29'h Street prior to 1936. Existing Conditions The stream and its buffer at this property exhibit characteristics of a heavily urbanized riparian environment. Development began is this urban corridor prior to 1936 and modifications have been made throughout the landscape in vicinity of the project area from that point forward. The stream lies at the northeast edge of the Tran property. The Tran property boundary extends a minimum of 5 feet and up to 13 feet northeast of the stream. Adjacent land use on the parcel to the northeast of the channel is a residence with fenced yard that is within 6 feet of the property boundary at its nearest. A row of western red cedar trees parallels the property line. Vegetation in the herb and shrub layer on the northeast side of the stream is sparse due to the dense canopy cover formed by the line of cedar trees (see Photograph 1). Many lower branches of the cedars were cleared by the neighbor in late July or early August 2015 which has opened up the understory to some extent along the western edge of the properties. The homeowner has planted a row of Oregon grape shrubs along the property boundary under City of Renton permit from November 2015 (Photograph 2). Vegetation on the southwest (a.k.a. river left) bank of the stream is a mix of lawn grasses extending to a rock retaining wall that forms a terrace which effectively stabilizes the slope leading up to the home. The stream bed lies in swale that is approximately 6 -8 feet lower than surrounding topography. A topographic map showing 2 foot contours in the vicinity of this property is provided in Figure 4. The stream is approximately 2 feet wide at OHW along the length of the channel on the Tran/Ly property (approximately 80 linear feet). Along much of the stream, the banks were stabilized with reused concrete riprap that appears to have been placed many decades ago. Hollow concrete blocks were placed more recently along 27 linear feet on river right (Photograph 3). The stream bed substrate is composed of a mix of sand and gravel with some silt. Flows are regulated by the dam that is about 100 feet upstream from the property. A culvert conveys water under NE 29 1h Street and off the property and to the north (Photograph 3). Existing Stream Buffer Functions Intact riparian buffers provide important ecological functions that can be described as supporting Hydrology, Biogeochemistry, Plant Community and Habitat/Fauna! Support systems (following Brinson et al. 1993, Brinson et al. 1995, AC Kindig 2003.). Riparian buffers in an urban environment are commonly degraded from decades of human encroachment and provide ecological functions to varying degrees. Hydrology functions may include maintenance of water quality to downstream waters including stream temperature regulation, and regulation of water quantity from delaying or retaining precipitation and stormwater runoff. Biogeochemistry functions provided by urban riparian buffers may include regulation of sediment and nutrient inputs to downstream waterways through streambank stabilization and filtration of runoff from upgradient systems. Riparian buffers may support diverse native and/or non-native plant communities. These plant communities may provide limited habitat opportunities for aquatic species, small birds or mammals, and beneficial insects with life history strategies that allow survival in narrow corridors within the urban environment. In this urban corridor, the primary goals for protecting and enhancing riparian buffers are to support cleaner water, temperature regulation, stream bank stabilization, and improved habitat for aquatic species and wildlife. Ecological functions provided by this stream are described under existing conditions in the sections below. The following section describes the proposed buffer restoration and enhancement activities and assesses potential for improvement in ecological functions that may result from this work. Hydrology Functions Under existing conditions, the stream and its buffer provide minimal to no hydrology functions to enhance water quality, regulate stormwater runoff or to provide flood storage. Tree canopy cover occurs only on river right bank of the channel. The channel is only partially shaded during mid-summer as the trees are northeast of the channel. These trees intercept some precipitation to help reduce storm runoff entering the stream. The channel banks are steep with old riprap placed many decades ago lining much of the channel on both sides. Sediment transport may occur to the stream from bare soil below the cedar canopy. Bioqeochemistry Functions Under existing conditions, the stream and its buffer provide low to moderate biogeochemistry functions. There is minimal vegetation in contact with the stream during normal flows due to riprap along steep channel banks. As the river left bank is in dense lawn vegetation, there is minimal potential for nutrient retention. The banks are stabilized and there is little chance for erosion or transport of sediment to the stream. River right bank has minimally vegetated soils which could erode and transport sediment to the stream. Plant Community Functions The cedar trees paralleling the property line are a native tree species. A row of native shrubs was planted in November 2015. Several native swordfern are growing along each bank of the channel. The remainder of the riparian buffer is dominated by non-native, predominantly herbaceous species including herbaceous lawn grasses and weeds and horticultural plants. Under existing conditions, the stream and its buffer provide low to moderate plant community functions. The cedar canopy on river right, provides a slight potential for insect and litterfall input to the creek that could support downstream aquatic food web cycling. Fauna/ Support/Habitat Functions Minimal to no native fauna! support or habitat functions are provided within the stream or its riparian buffer under its existing conditions. No fish are known to occur within this small, 2 foot wide, unnamed tributary. The property is immediately upstream of a long culvert. There is little habitat structure within the channel due to the straight, rip rap lined bank. The sparse understory plant community and adjacent developed areas limit potential species that could utilize this habitat. However, ducks and deer have been seen in this riparian corridor (A. Tran, Pers. Comm. 2015). Proposed Project: Streambank Restoration Removal of Concrete Block ond Bonk Reveqetation Approximately 27 linear feet of smooth, vertical concrete block wall which was installed at and below OHW within the past 5 years will be removed from the river right bank of the channel. A total of approximately 52 blocks will be removed. Prior existing rip rap block placed decades prior will be left in place along the bank upstream and downstream of the project work area. Soil will be removed on the slope so that the final grade of the river right channel bank will be no steeper than a slope of 2:1. The proposed stream bank restoration plan is provided in Sheets 2 and 3. Following removal of the blocks, a coir log wattle will be placed at OHW to minimize potential for erosion at the toe of slope while the grass vegetation gets established. The total area of disturbance will be approximately 60 square feet. All disturbed soils will be planted with erosion control grass seed per specification on Sheet 4. Straw mulch will be spread across the seeded area in a 1-2 inch thick layer to reduce potential for erosion during the establishment period. Native shrubs were installed along the property boundary immediately east of this proposed work area in November 2015. These shrubs will be left in place and will grow to cover much of this slope. Construction Sediment and Erosion Control Measures Construction best management practices will be used during block removal to minimize discharge of sediment to the stream. Work will be done during the driest months during a period of low flow in the channel. In-stream work to remove the bank armoring block will be done using work area isolation with a coir log staked in the channel to isolate the right bank from flows during construction. The coir log work area isolation will minimize potential for sediment transport downstream during work. Sheets 2 and 4 provide details of construction sediment and erosion control measures. Straw mulch will be installed on the disturbed areas to minimize erosion while seed gets established. Analysis of Project Effects The scale of the proposed planting project is very small and thus potential lift for ecosystem functions is limited. Hydrology Functions Removal of the concrete block wall will restore native channel banks on this 27 foot section of the creek. The river right slope will be flattened relative to condition prior to installation of block so potential for erosion will be lower than prior to wall installation. Removal of the blocks will improve hydrology functions relative to current or prior existing condition. Bioqeochemistry Functions The river right bank condition will be restored to equal or better to prior existing condition before the wall was installed. By removing the block, this reach of the stream will be in contact with native soil so will have minimal but incremental positive increase in biogeochemical functioning. Plant Community Functions The proposed project will restore plant community functions to be equal to or slightly higher than prior existing condition. Prior to installation of the block, the channel bank was in herbaceous grass vegetation. Native shrubs installed immediately upslope from this project area in November 2015 will grow up to provide cover over much of the disturbed area providing further incremental lift in plant community functions. Fauna/ Support/Habitat Functions The proposed project provides minimal to no change in faunal support/habitat functions. Removing the vertical wall and restoring 2:1 slope along this small section has potential to provide very small incremental increase in fauna I support/habitat functions for aquatic and terrestrial invertebrates and small vertebrates as there will be greater connectivity between upland areas and the creek. Monitoring and Maintenance Plan Photographs of baseline condition after block removal will be provided to the City within 30 days of project completion and at Year 1 and 3 to document that the bank remains stable and that herbaceous vegetation has attained a minimum of 80% ground cover. Conclusion In conclusion, the proposed project includes restoration of streambank by removing concrete block and installing grass seed on the disturbed soils along a 27 foot long reach of an unnamed tributary of May Creek. Sediment and erosion control measures are proposed to protect water quality in the stream during the installation and establishment period. The proposed project will restore the area to prior condition before installation of recent unpermitted concrete block along the bank. The proposed restoration will provide very small, incremental lift in ecosystem functions along this short reach of stream. We are happy to discuss the proposed project in further detail.

In order to continue processing your application, please choose one of the following options and submit the associated review materials: Option 1-Request to keep the unpermitted streambank wall To keep the unpermitted streambank wall, you will need to apply for and receive subsequent approval of a critical areas permit. The critical areas permit is a Type II permit subject to public notice and comment period. The permit application must provide evidence, utilizing Best Available Science, that the streambank armoring meets the minimum performance standards for restoration identified in Renton Municipal Code (RMC) 4-3-0SON3a. Be advised that comments submitted by citizens, government agencies, and/or Tribes may result in additional mitigation and/or alternative stabilization methods as conditions of any permit approval. Critical areas permit fees and all costs associated with any secondary review are the responsibility of the applicant. The submittal requirements for a critical areas permit are identified in RMC 4-8-120C. The critical areas permit will also require a public information sign. Please see the attached handout for information regarding the sign standards. Option 2 -Remove the unpermitted streambank wall A new critical areas exemption for restoration will be required to remove the wall as the previous exemption (case file LUAlS-000761) did not include this scope of work.

Additional materials are attached to meet permit submittal requirements as indicated on the Exemption from Critical Areas Regulations checklist. Project Introduction In August 2015, 7K Environmental was contracted to assist Alyssa Tran and Tony Ly with permit preparation for buffer enhancement plantings the stream buffer adjacent to their home. This permit was issued and planting occurred in November 2015 (LUA15-000761). In conjunction with this permit, the City is requiring that the homeowner remove 27 linear feet of concrete block retaining wall that was placed without permit along the northeast (a.k.a. river right) stream bank. The stream bank will be restored to prior condition and planted with native herbaceous vegetation to match site condition prior to wall installation in this reach. This report has been prepared to describe existing conditions on the site, discuss existing ecological functions in the stream buffer, and provide details of the proposed stream restoration activities along the unnamed stream that crosses their property. This letter report is designed to serve as the Standard Stream Study and Biological Assessment per Renton Municipal Code (RMC) 4-8-1200. 1 Project Site Description and Landscape Position The Tran property (Parcel number 334210-3365) is located at 2816 Kennewick Place NE in the City of Renton (see Figure 1 provided by City of Kent and Sheet 1). This parcel lies approximately 600 feet east of 1-405 in the developed urban neighborhood of Kennydale. A small, unnamed tributary of May Creek (See Figure 1) with an ordinary high water (OHW) width of approximately 2 feet lies near the northeast edge of the Tran property. No wetlands were observed on the property or adjacent to the property boundary as far as was visible from the Tran property. The unnamed tributary has a small watershed (estimated to be about 40 acres in size) upstream from the subject parcel. Approximately 80 feet upstream from the parcel, the stream is impounded by a 2-3 foot high concrete dam. A culvert carries water west under NE 291' Street. The stream conveys water approximately 700 feet north and west to its confluence with May Creek which joins Lake Washington approximately one mile further north and west. May Creek is known to be a fish bearing stream with documented presence with possible spawning for fall Chinook and coho salmon and winter run steelhead. No fish presence has been noted in the unnamed tributary on the Tran property (SalmonScape 2015). Site History The Tran/Ly family purchased the subject parcel in 2011. The existing dilapidated structure was demolished in 2012, and site grading was completed to allow for construction of a new residence under the new single family residence combination permit number CP12039. Final landscape elements were installed in 2012. Existing uses in the vicinity of the channel prior to 2012 included a home with landscaped yard including a swimming pool, fence, and retaining wall which paralleled the channel, approximately 15 feet to the south. Based on aerial photography analysis, the land was cleared and roads were constructed along the current path of Kennewick Road and NE 29 1' Street prior to 1936. Existing Conditions The stream and its buffer at this property exhibit characteristics of a heavily urbanized riparian environment. Development began is this urban corridor prior to 1936 and modifications have been made throughout the landscape in vicinity of the project area from that point forward. The stream lies at the northeast edge of the Tran property. The Tran property boundary extends a minimum of 5 feet and up to 13 feet northeast of the stream. Adjacent land use on the parcel to the northeast of the channel is a residence with fenced yard that is within 6 feet of the property boundary at its nearest. A row of western red cedar trees parallels the property line. Vegetation in the herb and shrub layer on the northeast side of the stream is sparse due to the dense canopy cover formed by the line of cedar trees (see Photograph 1). Many lower branches of the cedars were cleared by the neighbor in late July or early August 2015 which has opened up the understory to some extent along the western edge of the properties. The homeowner has planted a row of Oregon grape shrubs along the property boundary under City of Renton permit from November 2015 (Photograph 2). Vegetation on the southwest (a.k.a. river left) bank of the stream is a mix of lawn grasses extending to a rock retaining wall that forms a terrace which effectively stabilizes the slope leading up to the home. The stream bed lies in swale that is approximately 6 -8 feet lower than surrounding topography. A topographic map showing 2 foot contours in the vicinity of this property is provided in Figure 4. The stream is approximately 2 feet wide at OHW along the length of the channel on the Tran/Ly property (approximately 80 linear feet). Along much of the stream, the banks were stabilized with reused concrete riprap that appears to have been placed many decades ago. Hollow concrete blocks were placed more recently along 27 linear feet on river right (Photograph 3). The stream bed substrate is composed of a mix of sand and gravel with some silt. Flows are regulated by the dam that is about 100 feet upstream from the property. A culvert conveys water under NE 29'h Street and off the property and to the north (Photograph 3). Existing Stream Buffer Functions Intact riparian buffers provide important ecological functions that can be described as supporting Hydrology, Biogeochemistry, Plant Community and Habitat/Fauna! Support systems (following Brinson et al. 1993, Brinson et al. 1995, AC Kindig 2003.). Riparian buffers in an urban environment are commonly degraded from decades of human encroachment and provide ecological functions to varying degrees. Hydrology functions may include maintenance of water quality to downstream waters including stream temperature regulation, and regulation of water quantity from delaying or retaining precipitation and stormwater runoff. Biogeochemistry functions provided by urban riparian buffers may include regulation of sediment and nutrient inputs to downstream waterways through streambank stabilization and filtration of runoff from upgradient systems. Riparian buffers may support diverse native and/or non-native plant communities. These plant communities may provide limited habitat opportunities for aquatic species, small birds or mammals, and beneficial insects with life history strategies that allow survival in narrow corridors within the urban environment. In this urban corridor, the primary goals for protecting and enhancing riparian buffers are to support cleaner water, temperature regulation, stream bank stabilization, and improved habitat for aquatic species and wildlife. Ecological functions provided by this stream are described under existing conditions in the sections below. The following section describes the proposed buffer restoration and enhancement activities and assesses potential for improvement in ecological functions that may result from this work. Hydrology Functions Under existing conditions, the stream and its buffer provide minimal to no hydrology functions to enhance water quality, regulate stormwater runoff orto provide flood storage. Tree canopy cover occurs only on river right bank of the channel. The channel is only partially shaded during mid-summer as the trees are northeast of the channel. These trees intercept some precipitation to help reduce storm runoff entering the stream. The channel banks are steep with old riprap placed many decades ago lining much of the channel on both sides. Sediment transport may occur to the stream from bare soil below the cedar canopy. Bioqeochemistry Functions Under existing conditions, the stream and its buffer provide low to moderate biogeochemistry functions. There is minimal vegetation in contact with the stream during normal flows due to riprap along steep channel banks. As the river left bank is in dense lawn vegetation, there is minimal potential for nutrient retention. The banks are stabilized and there is little chance for erosion or transport of sediment to the stream. River right bank has minimally vegetated soils which could erode and transport sediment to the stream. Plant Community Functions The cedar trees paralleling the property line are a native tree species. A row of native shrubs was planted in November 2015. Several native swordfern are growing along each bank of the channel. The remainder of the riparian buffer is dominated by non-native, predominantly herbaceous species including herbaceous lawn grasses and weeds and horticultural plants. Under existing conditions, the stream and its buffer provide low to moderate plant community functions. The cedar canopy on river right, provides a slight potential for insect and litterfall input to the creek that could support downstream aquatic food web cycling. Fauna/ Support/Habitat Functions Minimal to no native fauna I support or habitat functions are provided within the stream or its riparian buffer under its existing conditions. No fish are known to occur within this small, 2 foot wide, unnamed tributary. The property is immediately upstream of a long culvert. There is little habitat structure within the channel due to the straight, rip rap lined bank. The sparse understory plant community and adjacent developed areas limit potential species that could utilize this habitat. However, ducks and deer have been seen in this riparian corridor (A. Tran, Pers. Comm. 2015). Proposed Project: Streambank Restoration Removal of Concrete Block and Bonk Reveqetotion Approximately 27 linear feet of smooth, vertical concrete block wall which was installed at and below OHW within the past 5 years will be removed from the river right bank of the channel. A total of approximately 52 blocks will be removed. Prior existing rip rap block placed decades prior will be left in place along the bank upstream and downstream of the project work area. Soil will be removed on the slope so that the final grade of the river right channel bank will be no steeper than a slope of 2:1. The proposed stream bank restoration plan is provided in Sheets 2 and 3. Following removal of the blocks, a coir log wattle will be placed at OHW to minimize potential for erosion at the toe of slope while the grass vegetation gets established. The total area of disturbance will be approximately 60 square feet. All disturbed soils will be planted with erosion control grass seed per specification on Sheet 4. Straw mulch will be spread across the seeded area in a 1-2 inch thick layer to reduce potential for erosion during the establishment period. Native shrubs were installed along the property boundary immediately east of this proposed work area in November 2015. These shrubs will be left in place and will grow to cover much of this slope. Construction Sediment and Erosion Control Measures Construction best management practices will be used during block removal to minimize discharge of sediment to the stream. Work will be done during the driest months during a period of low flow in the channel. In-stream work to remove the bank armoring block will be done using work area isolation with a coir log staked in the channel to isolate the right bank from flows during construction. The coir log work area isolation will minimize potential for sediment transport downstream during work. Sheets 2 and 4 provide details of construction sediment and erosion control measures. Straw mulch will be installed on the disturbed areas to minimize erosion while seed gets established. Analysis of Project Effects The scale of the proposed planting project is very small and thus potential lift for ecosystem functions is limited. Hydrology Functions Removal of the concrete block wall will restore native channel banks on this 27 foot section of the creek. The river right slope will be flattened relative to condition prior to installation of block so potential for erosion will be lower than prior to wall installation. Removal of the blocks will improve hydrology functions relative to current or prior existing condition. Bioqeochemistry Functions The river right bank condition will be restored to equal or better to prior existing condition before the wall was installed. By removing the block, this reach of the stream will be in contact with native soil so will have minimal but incremental positive increase in biogeochemical functioning. Plant Community Functions The proposed project will restore plant community functions to be equal to or slightly higher than prior existing condition. Prior to installation of the block, the channel bank was in herbaceous grass vegetation. Native shrubs installed immediately upslope from this project area in November 2015 will grow up to provide cover over much of the disturbed area providing further incremental lift in plant community functions. Fauna/ Support/Habitat Functions The proposed project provides minimal to no change in fauna! support/habitat functions. Removing the vertical wall and restoring 2:1 slope along this small section has potential to provide very small incremental increase in faunal support/habitat functions for aquatic and terrestrial invertebrates and small vertebrates as there will be greater connectivity between upland areas and the creek. Monitoring and Maintenance Plan Photographs of baseline condition after block removal will be provided to the City within 30 days of project completion and at Year 1 and 3 to document that the bank remains stable and that herbaceous vegetation has attained a minimum of 80% ground cover. Conclusion In conclusion, the proposed project includes restoration of stream bank by removing concrete block and installing grass seed on the disturbed soils along a 27 foot long reach of an unnamed tributary of May Creek. Sediment and erosion control measures are proposed to protect water quality in the stream during the installation and establishment period. The proposed project will restore the area to prior condition before installation of recent unpermitted concrete block along the bank. The proposed restoration will provide very small, incremental lift in ecosystem functions along this short reach of stream. We are happy to discuss the proposed project in further detail.
