Proposed roadway improvements will intrude into the buffer of Wetland A, an existing category H wetland, and portions of the corresponding 100-foot wetland buffer will be temporarily and permanently impacted by the roadway improvements. Wetland buffer intrusion b an essential public facility is permitted pursuant to Federal Way Revised Code (FWRC) 19.175.040 y Structures, improvements and land sur face modrftcatiort criteria,' The wetland report prepared by Landau Associattivilhirr regulated wetland hujjers, subject to es noted that the roundabout design creates unavoidable impacts on the wetland buffer and addresses the decisional criteria for an essential public facility. ADDITIONAL INFORMATION REQUESTED: Additional information, as discussed below, is required before an environmental determination can be issued. I) Wetland Proximity — The wetland buffer is reduced to approximately five feet between wetland delineation points F9 and F I2, and some of the roadway work appears to be in close proximity to the actual wetland. Provide enlarged details of the work that is proposed in the wetland buffer between these points, including the area of construction adjacent to these points to ensure that all work and construction areas are located outside of the actual wetland area. For example, if there are retaining walls in the buffer, confirm that the wall footings will be located outside of the wetland. Please note that any intrusion beyond the buffer and into the wetland will require additional Iand use review and a Process IV public hearing. 2) Buffer Restoration —Identify how those portions of wetland buffer that are temporarily disturbed will be restored, and provide a planting plan for those areas. 1 (3) Essential public facilities, public utilities and other public imp+�oventents. The director of community development may Permit the placement afan essential public Facility, public utility or other public irnprovemernts in a regulated wetland buffer if he or she determines that the line or improvernent must traverse the buffer because no feasible or alternative Io i CC an analysis of technology and system efficiency, and the speci€ic location and extent of the intrusion into th��C constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. MAR 21 2012 CITY OF FEDERAL WAY CDS Mr. John Mulkey February 15, 2012 Page 2 of 2 3) Wetland — Depict the location of any proposed drainage facilities associated with the improvement. If there are no :known discharge points to the wetland, how wroadway Ill the roadway runoff impact it or the buffer? 4) SEPA Checklist — Please revise the SEPA checklist to address the following: B.M.1 This portion of the checklist Motes that the project will create 10,000 SF of impervious surface, and natural drainage there are no known discharge practices are proposed. The wetland report notes that Points to the wetland.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NON -PROJECT PROPOSALS Complete this checklist for non -project proposals, even though questions may be answered "does not apply." In addition, complete the Supplemental Sheet for Non -Project Actions (part D). For non -project actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

None known, the project area is just north and west of the project area where WSDOT is constructing intersection improvements along State Route 18 and Interstate 5. 10. List any government approvals or permits that will be needed for your proposal, if known. Potentially an access franchise agreement with WSDOT Approval will be required from the City of Federal Way for roundabout construction activities that will occur within the existing wetland buffer. l L Give a brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. The existing intersection is a three legged T intersection with traffic controlled by a slop sign at west bound South 3446 Way. The purpose of the project is to improve intersection operations through the installation of a two- lane roundabout. New sidewalks, roadway illumination and landscaping will also serve to improve the safety and aesthetic character at the intersection. Bulletin #050 —August 19, 2004 Page 2 of 12 k:\Handouts\Environmental Checklist Proposed Improvements for the intersection of S 344`h Way at Weyerhaeuser Way S include_ ♦ Roadway widening as required for constructing a nvo-lane roundabout. ♦ Installing curb, gutter, sidewalk and bike lanes along both sides of the roadway. ♦ Potential retaining ►valls to mitigate impacts to private property and br sensitive areas. ♦ Upgrading the stormwater collection, treatment, and detention facilities. ♦ Installing a new roachvay illumination system. ♦ Installing landscape planter strips along both sides of the roadway and within the roundabout_ This project extends improvements on all three legs of the existing intersection, and will provide smooth transitions to existing roadways, extending approximately 300 feet from the center of the intersection. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project is located in the City of Federal Way at the intersection of South 344`h Way and Weyerhaeuser Way, in King County, Washington: The project area is within the Puyallup/White watershed [Water Resource Inventory Area (WRIA) 101 in Sections 21 and 22, Township 21 North, and Range 4 East. This project extends improvements on all three legs of the existing intersection of South 344`h Way and Weyerhaeuser Way, and will provide smooth transitions to existing roadways, extending approximately 300 feet from the center of the intersection. B. ENVIRONMENTAL ELEMENTS EARTH a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other. The site is relatively flat through the project area — there are some grade changes just west of the paved portion of Weyerhaeuser Way. The existing roadway is relatively flat through the project area. b. What is the steepest slope on the site (approximate percent slope)? The steepest slope is west of Weyerhaeuser Way is approximately a 10% slope. C. What general types of soils are found on the site (for example, clay, sand, gravel, peat, mulch)? If you know the classification of agricultural soils, specify them and note any prime farmland. The project area is mostly paved roadway and gravel right of way. A wetland area is on the west side of Weyerhaeuser Way; much of the wetland buffer is already impacted from the existing roadway and right of way. According to the USDA, MRCS web soil survey, soils in the vicinity include Alderwood gravelly sandy loam (formed in glacial till) within the uplands and Shalcar muck (typically woody organic deposits overlying alluvium or glacial ounvash or glaciomarine deposits) within the wetland area. The roadway right of way and roadsides most likely contain compacted fill material. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No surface indicators of unstable soils in the immediate vicinity. k:\Handouts\Environmental Checklist Bulletin #050 — August 19, 2004 Page 3 of 12 e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Fill ivill be required for constructing the roundabout, all necessary fill will be from an approved site and ivill comply with all City of Federal Way requirements. It is estimated that 1,100 cu yds offill will be required for the site. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. The site is relatively flat and erosion is not anticipated to occur during construction activities. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project ivill increase pavement in the project area, it is anticipated the impervious surface coverage ivill increase by 10, 000 sf. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. A Temporary Erosion and Sediment Control Plan (TESQ and Construction Storm Water Pollution Prevention Plan (CSGYPPP) ivill be in place during construction activities. 2. MR. a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke, etc.) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. The project replaces an existing intersection controlled by a stop sign ivith a roundabout. Temporary construction impacts such as minor additional dust emissions are possible. When the project is completed the emissions should not increase. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. None knovvn or anticipated. c. Proposed measures to reduce or control emissions or other impacts to air, if any. If needed during construction the site will be sprayed tvith ivater for dust control. 3. WATER a. Surface 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, and wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There is a Category 11 wetland; approximately 37, 800 sf in size adjacent to the ►vest of the project area. It is a depressional ivetland and has no known outlet or surface water connections_ The project has been designed to avoid impacting the existing tivetland The existing road currently impacts the ivetland buffer. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters?

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply." Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. USE OF CHECKLIST FOR NON -PROJECT PROPOSALS Complete this checklist for non -project proposals, even though questions may be answered "does not apply." In addition, complete. the Supplemental Sheet for Non -Project Actions (part D). For non -project actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer," and "affected geographic area," respectively.

The existing intersection is a three legged T-intersection with traffic controlled by a stop sign at west bound South 344`t' Waj+ The purpose of the project is to improve intersection operations through the installation of a two- lane roundabout. New sidewalks, roadway illumination and landscaping will also serve to improve the Bulletin #050 — August 19, 2004 Page 2 of 12 k:\Handouts\Environmental Checklist safety and aesthetic character at the intersection. Proposed Improvements for the intersection of S 344"' Way at Weyerhaeuser Way S include. - Roadway widening as required for constructing a two-lane roundabout. ♦ Installing curb, gutter, sidewalk, and bike lanes along both sides of the roadway. ♦ Two retaining walls to mitigate/prevent impacts to private property and/or sensitive areas. ♦ Upgrading the stormwater collection, treatment, and detention facilities. ♦ Installing a new roadway illumination system. ♦ Installing landscape planter strips along both sides of the roadway and within the roundabout. This project extends improvements on all three legs of the existing intersection, and will provide smooth transitions to existing roadways, extending approximately 300 feet from the center of the intersection. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project is located in the City of Federal Way at the intersection of South 344`►' Way and Weyerhaeuser Way, in King County, Washington. The project area is within the PuyalluplWhite watershed [Water Resource Inventory Area (WRM) 10] in Sections 21 and 22, Township 21 North, and Range 4 East. This project extends improvements on all three legs of the existing intersection of South 344"' Way and Weyerhaeuser Way, and will provide smooth transitions to existing roadways, extending approximately 300 feet from the center of the intersection. B. ENVIRONMENTAL ELEMENTS EARTH a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other. The site is relatively flat through the project area — there are some grade changes just west of the paved portion of Weyerhaeuser Way. The existing roadway is relatively flat through the project area. b. What is the steepest slope on the site (approximate percent slope)? The steepest slope is west of Weyerhaeuser Way is approximately a 10% slope. What general types of soils are found on the site (for example, clay, sand, gravel, peat, mulch)? If you know the classification of agricultural soils, specify them and note any prime farmland. The pralect area is mostly paved roadway andgravel avel right of way. A wetland area is on the west side of Weyerhaeuser Way: much q f the wetland buffer is already impacted from the existing roadway and right of way. According to the USDA, NRCS web soil survey, soils in the vicinity include Alderwood gravelly sandy loam (formed in glacial till) within the uplands and Shalcar muck (typically woody organic deposits overlying alluvium or glacial outwash or glaciomarine deposits) within the wetland area. The roadway right of way and roadsides most likely contain compacted fill material. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No surface indicators of unstable soils in the immediate vicinity. Bulletin #050 — August 19, 2004 Page 3 of 12 k:\Handouts\Environmental Checklist e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Fill will be required for constructing the roundabout, all necessary fill will be from an approved site and will comply with all City of Federal Way requirements. It is estimated that 1,100 cu yds offill will be required for the site. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. The site is relatively flat and erosion is not anticipated to occur during construction activities. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The project will increase pavement in the project area, it is anticipated the impervious surface coverage will increase by 10, 000 sf. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any. A Temporary Erosion and Sediment Control Plan (TESL) and Construction Storm Water Pollution Prevention Plan (CSWPPP) will be in place during construction activities. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke, etc.) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. The project replaces an existing intersection controlled by a stop sign with a roundabout. Temporary construction impacts such as minor additional dust emissions are possible. When the project is completed the emissions should not increase. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. None known or anticipated. C. Proposed measures to reduce or control emissions or other impacts to air, if any. If needed during construction the site will be sprayed with water for dust control. WATER a. Surface 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, and wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. There is a Category II wetland, approximately 37, 800 sf in size adjacent to the west of the project area. It is a depressional wetland and has no known outlet or surface water connections, much of the wetland is located on private property. The project has been designed to avoid impacting the existing wetland. The existing road currently impacts the wetland buffer, the road improvements will also have temporary and permanent impacts to the wetland buffer. Bulletin #050 — August 19, 2004 Page 4 of 12 k:\Handouts\Environmental Checklist 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. The project will not require any in -water work. Currently the existing roadway impacts the wetland buffer on the east side of the wetland/west side of Weyerhaeuser Way. The new roundabout will not impact the wetland area or its wetland functions but will increase impacts to the eastern portion of the wetland buffer. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. None. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. No, per the FEMA map number 53033C1250 F (map revised May 16, 1995) panel 1250 of 1725, the project is outside of any flood area. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No water or waste materials will be discharged into the wetland or any other surface waters. Stormwater runoff currently sheet flows into buffer area and into the existing wetland. The Project will provide bioretention cells with 18-in depth soil filter media, providing an enhanced level water quality treatment per WSDDE BMP standards. The roadway and roundabout design spec f cally avoided wetland impacts and minimized the wetland buffer impact as much as possible in compliance with FYYRC 19,175.040. b. Ground 1) Will ground water be withdrawn, or will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. Iffeasible stormwater will be infiltrated through bioretention cells and porous sidewalks. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material will be discharged into the ground. c. Water Runoff (including stormwater) 1) Describe the source of runoff (including stormwater) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. The project creates an additional 10, 000 sf of impervious surface. The new stormwater system will incorporate natural drainage practices, including bioretention and porous sidewalks, to the extent feasible. Stormwater that cannot be infiltrated will be detained and Bulletin #050 — August 19, 2004 Page 5 of 12 k:\Handouts\Environmental Checklist treated through conventional methods (i.e., underground pipeslchambers and cartridge filters) in compliance with stormwater requirements. Stormwater runoffwill be collected and conveyed with catch basins and pipes and curb openings. Runoff will continue to discharge at the natural locations, including treated stormwater discharging into the wetland buffer (see figure 2, moist buffer area). 2) Could waste materials enter ground or surface waters? If so, generally describe. Wastewater will not be discharged into ground or surface waters therefore no waste materials will enter waters. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any. All stormwater runoff will comply with the existing Federal Way regulations for stormwater management, including the requirements of the 2009 King County Surface Water Design Manual, the City's NPDES, and the FWRC. Stormwater runoff will be collected and conveyed with catch basins and pipes and curb openings. Runoffwill continue to discharge at the natural locations, including treated stormwater discharging into the wetland buffer (see figure 2, moist buffer area). Stormwater runoff currently sheet flows into buffer area and into the existing wetland. The Project will provide bioretenlion cells with 18-in depth soil filter media, providing an enhanced level water quality treatment per WSDOE BMP standards prior to water going into the wetland buffer. The FWRC section 19.175.040 allows for public improvements within a wetland buffer provided no feasible alternative exists and the intrusion constitutes the minimum necessary to meet the requirements of the public facility. Additionally, wetkmd buffer plantings (restoration) will be provided for the temporary impacts to the wetland buffer. This includes using native grasses appropriate for wetland buffers to establish erosion control. 4. PLANTS a. Check or circle types of vegetation found on the site. X deciduous tree: alder, maple, aspen, other X evergreen tree: fir, cedar, pine, other X shrubs X grass pasture crop or grain wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other _ water plant: water lily, eelgrass, milfoil, other X other types of vegetation: Salal, Pacific and Scouler Willows, sword fern, Douglas spirea, nootka rose b. What kind and amount of vegetation will be removed or altered? Currently the area adjacent to the road consists of various grasses, willow trees, Douglas -fir trees, blackberries and salal. Some oPhe trees and the shrubs will need to be removed. The FWRCprovides an exemption for tree removal for roadway projects (FWRC 19.120.030(13)). List threatened or endangered species known to be on or near the site. In a letter sent September 28, 2011, Washington Department of Natural Resources stated there was no record of endangered plants or high quality native ecosystems in the project area. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if Bulletin #050 — August 19, 2004 Page 6 of 12 k:\Handouts\Environmental Checklist any. Project landscaping will use native plant species for the roundabout landscaping and any new landscaping along the roadside and planter strips. Temporary wetland buffer impacts will be mitiga d by providing native buffer plantings within the wetland buffer once the work is completed There is a narrow strip of buffer between the wetland and the new roadway. A combination of native plantings including nootka rose, salmonberry, red osier dogwood, salal, snowberry, etc will be planted in the area of temporarily disturbed wetland buffer. 5. ANIMALS a. Circle any birds and animals that have been observed on or near the site or are known to be on or near the site. birds: hawk, heron, eagle, songbirds, other: mammals: deer, bear, elk, beaver, other: Possums, Raccoons fish: bass, salmon, trout, herring, shellfish, other: b. List any threatened or endangered species known to be on or near the site. The site is located in a developed area, with Interstate Five to the west, Highway 18 to the north, a developed Business Park to the east and residential properties to the south. The WDFW public GIS for Priority Habitat and Species does not show any potential for federally listed endangered species in the project area. The existing wetland on the site is isolated and does not have a surface water connection to any fish bearing streams. Due to all these factors, it is not anticipated that threatened or endangered species are using the site. C. Is the site part of a migration route? If so, explain. Much of the Pacific Northwest is considered part of the Pacific Flyway, which is used as a migration route by many different bird species. d. Proposed measures to preserve or enhance wildlife, if any. Native vegetation will be used as part of the landscape materials for the roundabout project. Additionally temporary impacts to the wetland buffer will be mitigated for by providing a combination of native plantings including nootka rose, salmonberry, red osier dogwood, salal, snowberry, etc. 6. ENERGY AND NATURAL RESOURCES a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. The project will use electricityfor lighting the intersection. The intersection already has lights in place and therefore electricity is already on site to support any additional lighting requirements. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. No, the roadway improvement work is at the ground level and will not block or impact the potential for the use of solar energy on adjacent properties. C. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any. Bulletin #050 — August 19, 2004 Page 7 of 12 k:\Handouts\Environmental Checklist The project improves the efficiency of travel within the intersection, replacing a stop sign with a roundabout, eliminating long idle times far vehicles, which should provide a minor improvement to vehicle energy efficiency. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste that could occur as a result of this proposal? If so, describe. None anticipated. During construction a TESC Plan and CSWPP (including a spill control plan) will be in place along with typical construction safety plans. 1) Describe special emergency services that might be required. None should be required unless there is an accident during construction. 2) Proposed measures to reduce or control environmental health hazards, if any. A TESC Plan and CSWPPP (including spill control plan) will be in place and applicable safety procedures will be followed during the construction. b. Noise 1) What types of noise exist in the area that may affect your project (for example: traffic, equipment operation, other)? The project area is close to both Interstate 5 and Highway 18, however existing traffic noise should not impact the intersection. 2) Wliat types and levels of noise would be created by or associated with the project on a short-term or long-term basis (for example: traffic, construction operation, other)? Indicate what hours noise would come from the site. The project will create temporary noise impacts from construction work at the intersection. The roundabout will eliminate an existing stop sign and the flow of existing traffic should not increase noise in the area. 3) Proposed measures to reduce or control noise impacts, if any. Construction noise will be limited to normal daylight hours as allowed in WAC 173-60-050 and applicable regulations in the FWRC. 8. LAND AND SHORELINE USE a. What is the current use of the site and adjacent properties? The area to the north of the site is Highway 18. east of the site is developed with a business park/business campus, south of the site is developed with single family residential and west of the site is undeveloped land and wetla►td, and further west is Interstate 5. The Federal Way land use map shows the area land uses as vacant land and office park. b. Has the site been used for agriculture? If so, describe. The site is currently not used for agriculture; past uses in the area could have included timber harvesting since the surrounding area was owned by the Weyerhaeuser Company. C. Describe any structures on the site. Bulletin #050 — August 19, 2004 Page 8 of 12 k:\Handouts\Environmental Checklist The project area is a three legged intersection; the only structure on the site is the bus stop shelter on the east side of Weyerhaeuser Way. There is no bus shelter at the bus stop on the west side of Weyerhaeuser Way. d. Will any structures be demolished? If so, what? No structures will be demolished however, the existing bus shelter on the east side will be moved slightly east to accommodate the new roadway improvements. e. What is the current zoning classification of the site? The site is zoned for Office Park according to the Federal Way Zoning Map. f. What is the current comprehensive plan designation of the site? The comprehensive plan map shows the area designation as Office Park. g. If applicable, what is the current shoreline master program designation of the site? There are no shorelines in the project area. h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. The critical area map shows a wetland in the project area. One wetland was found during the wetland reconnaissance. The wetland area was delineated. The proposed design avoids direct wetland impacts and only impacts the existing wetland buffer. i. Approximately how many people would reside or work in the completed project? None. j, Approximately how many people would the completed project displace? None. k. Proposed measures to avoid or reduce displacement impacts, if any. None needed. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any. By replacing the existing intersection with a roundabout, the project improves the existing intersection providing a safer and more functional roadway. Additionally sidewalks will be added on the west side of the project where none currently exist. This is compatible with the ofrce park zoning designation and provides easier and safer opportunities to use public transportation and safer access for those driving to work at the existing office park. The FWRC section 19.175.040 allows for wetland buffer encroachment if no feasible alternative exists and the encroachment is the minimum necessy. A combination of native plantings including nootka rose, salmonber+y, red osier dopmod, salal, snowberty, etc will be planted in the area of ternporarily disturbed wetland buffer to provide restoration. 9. HousING a. Approximately how many units would be provided, if any?

Figure Proposed Mitigation 2 LANDAU ASSOCIATES TECHNICAL MEMORANDUM ENVIROMENTAL I GEOFEC ICAO I r ARM RESOURCES TO: Steve 011ing, PE, Tetra Tech FROM: Theresa Turpin and Jessica Stone, Landau Associates DATE: March 15, 2012 RE: WEYERHAEUSER WAY ROUNDABOUT WETLAND BUFFER IMPACTS FEDERAL WAY, WASHINGTON NTRODUCTION Tetra Tech is providing design consultant services to the City of Federal Way (City) to convert an existing three-legged T-intersection to a three-legged roundabout (project). The project is located in Federal Way at the intersection of South 344`h Way and Weyerhaeuser Way South. Landau Associates was hired as the subconsultant to assist with the project including permitting support. This technical memorandum provides a planting plan for temporary impacts within the wetland buffer due to project construction activities. The project location is presented in Figure 1. Landau Associates identified one Category II wetland (Wetland A) adjacent to the proposed project. The existing roadway already impacts the wetland buffer and the project will have temporary and permanent wetland buffer impacts. There will be 7,323 square feet (ft) of new permanent buffer impacts at the southern end of the site from the roundabout installation and the sidewalk, lighting and landscaping improvements. The project will also have 3,330 ft2 of temporary buffer impacts associated with project construction. The project has been designed to avoid all impacts to the wetland area or wetland functions. Figure 2 presents the wetland location, the proposed project, and the temporary and permanent buffer impacts. The Federal Way Revised Code (FWRC) allows public roads within wetland buffers [FWRC 19.17.040(3)] provided there is no feasible alternative. The wetland delineation and project impacts are described in the Draft Wetland Delineation Report, South 344`h Way at Weyerhaeuser Way South (Landau Associates 2011). Due to the limited amount of right-of-way, providing 1 to 1 wetland buffer mitigation for all permanent buffer impacts is not feasible. EXISTING BUFFER The existing buffer area is healthy. It is dominated by a Douglas -fir (Pseudotsuga menziesii) forest with a native understory. Some deciduous trees, such as red alder (Alnus rubra) are present within the inner buffer area near the wetland boundary. Understory vegetation within the buffRES BM FU E D MAR 21 2012 950 Pacific Avenue, Suite 515 • Tacoma, WA 98402 ■ (253) 926-2493 • fax (253) 926-2531 • WvFA Iah abi69Uf-AL WAY '} 1 salal (Gaultheria shallon), sword fern (Polystichum munitum), and trailing blackberry (Rubus ursinus), with some nootka rose (Rosa nutkana) and Douglas spirea (Spiraea douglasii) in the buffer near the wetland boundary. Weyerhaeuser Way South and its roadway prism run north to south near the eastern edge of the wetland, currently impacting most of the wetland buffer. Only a narrow strip of vegetated buffer area, primarily growing on the roadside prism, is present in this area. Despite the presence of the roadway in the buffer, the vegetation contains little to no invasive species. The western and northern buffer of Wetland A (located on private property) is not impacted and is dominated by the native vegetation as described above. Buffer mitigation through enhancement is not recommended since the condition of the existing native vegetative buffer is healthy (i.e. little or no non-native invasive species present). PROJECT CONSTRUCTION The roundabout, sidewalk, lighting, and landscaping improvements will be conducted adjacent to the northern end of Wetland A. The project construction will temporarily impact 3,330 ftz of wetland buffer. At its closest, the project will be 1.74 ft from the edge of the wetland. This location of the project consists of a structural earth wall to support the sidewalk, planter strip, and roundabout. The structural earth wall will be constructed using geogrids and will have a concrete block face toward the wetland; this design will allow construction to be entirely within the wetland buffer with no wetland disturbance. The attached drawing, S-01, shows the structural earth wall, its design, and the adjacent wetland area. Silt and high visibility fencing will be installed along the clearing and grading limits between the project and the wetland. Stormwater best management practices will be in -place to prevent construction stormwater runoff into the wetland and undisturbed buffer area. PLANTING PLAN As presented on Figure 2, much of the temporary impacted area will consist of a narrow strip of buffer between the wetland and the new roadway. Once the project construction is completed, this area will be steep, narrow, and difficult to access and maintain. Landau Associates proposes that this area be revegetated with a native grass mix to establish erosion control and, where planting and maintenance is feasible, plant a mix of shade -tolerant shrub species to provide habitat and prevent the establishment of invasive species. Plant species were selected based on their tolerance to poor or disturbed soils, slope stabilization, moisture tolerance, and shade tolerance. The table below provides the recommended plant species for the buffer replanting area: Species Scientific Name Common Name Number of Plants Form Grasses 03/16/12 YA11 87\002 020\R\Buffer Plan Technical Memo\TM_Planling Plan.docx 2 Shrubs will be planted on an average planting density of one shrub planted an average of 4-ft on center. As the temporarily impacted area will be cleared and graded, there will be no effort to preserve existing vegetation. Planting areas are presented on Figure 2. The project will include landscaping improvements (planting strip) between the sidewalk and the roadway. The buffer replanting will be completed under the same planting specifications and maintenance requirements as the landscape improvements for the project. These project specifications include: • 8-02 Roadside Restoration. This section provides the topsoil (decompaction) requirements, planting area preparation, soil amendments, fertilizers and mulch for seeding. 8-02.3(8) Planting. This section provides the specifications for planting, fertilizers, mulch, and plant establishment for plant installation. 8-03 Irrigation Systems. This section provides the construction requirements, flushing and testing, electrical service, and water connection for the irrigation system. • 9-14. Erosion Control and Roadside Planting. This section provides the bioretention soil mix and topsoil requirements. Planting and site preparation specifications are provided in the project's landscape design figures.

Proposed roadway improvements will intrude into the buffer of Wetland A, an existing category II wetland, and portions of the corresponding 100-foot wetland buffer will be temporarily and permanently impacted by the roadway improvements. Wetland buffer intrusion by an essential public facility is permitted pursuant to Federal Way Revised Code (FWRC) 19.175.040 Structures, improvements and land surface modification within regulated wetland buffers, subject to criteria.' The wetland report prepared by Landau Associates noted that the roundabout design creates unavoidable impacts on the wetland buffer and addresses the decisional criteria for an essential public facility. ADDITIONAL INFORMATION REQUESTED: Additional information, as discussed below, is required before an environmental determination can be issued. 1) Wetland Proximity — The wetland buffer is reduced to approximately five feet between wetland delineation points F9 and F 12, and some of the roadway work appears to be in close proximity to the actual wetland. Provide enlarged details of the work that is proposed in the wetland buffer between these points, including the area of construction adjacent to these points to ensure that all work and construction areas are located outside of the actual wetland area. For example, if there are retaining walls in the buffer, confirm that the wall footings will be located outside of the wetland. Please note that any intrusion beyond the buffer and into the wetland will require additional land use review and a Process W public hearing. 2) Buffer Restoration — Identify how those portions of wetland buffer that are temporarily disturbed will be restored, and provide a planting plan for those areas. t (3) Essential public facilities, public utilities and other public improvements. The director of community development may permit the placement of an essential public facility, public utility or other public improvements in a regulated wetland buffer if he or she determines that the line or improvement must traverse the buffer because no feasible or alternative location exists based on an analysis of technology and system efficiency, and the specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. February 15, 2012 Page 2 of 2 3) Wetland — Depict the location of any proposed drainage facilities associated with the roadway improvement. If there are no known discharge points to the wetland, how will the roadway runoff impact it or the buffer? 4) SEPA Checklist — Please revise the SEPA checklist to address the following: B.3.C.1 This portion of the checklist notes that the project will create 10,000 SF of impervious surface, and natural drainage practices are proposed. The wetland report notes that there are no known discharge points to the wetland. Please expand this checklist response to discuss where the drainage system(s) will be located, if drainage will impact the wetland or the wetland buffer, and depict where drainage will discharge, including a discussion of "discharge at the natural location." B.3.d Revise this response to include mitigation under FWRC 19.175.040, and buffer restoration. B.4.d Revise this response to include buffer restoration. B.5.d Revise this response to include wetland buffer restoration to mitigate wildlife impacts. B.8.1 Revise this response to include buffer restoration. B.10.A Denote if there will be any walls included in this project, including adjacent to the wetland buffer.

Landau Associates was hired as the subconsultant to assist with the project including providing the wetland delineation and report. The location of the roundabout was based on several factors including limiting impacts as much as possible to the site's existing wetland. Purpose The project purpose is to improve an existing three legged T-intersection by installing a two-lane roundabout. The roundabout, like the existing intersection, will have three -legs. New sidewalks, roadway illumination, and landscaping will improve the safety and aesthetic character at the intersection. include: Proposed Improvements Proposed Improvements for the intersection of South 344"' Way at Weyerhaeuser Way South ■ Roadway widening as required for constructing a two-lane roundabout ■ Installing curb, gutter, and sidewalk along both sides of the roadway ■ Potentially adding retaining walls to mitigate impacts to private property and/or sensitive areas ■ Upgrading the stormwater collection, treatment, and detention facilities • Installing a new roadway illumination system ■ Installing landscaping planter strips along both sides of the roadway and within the roundabout • Moving the existing bus shelter on the east side of Weyerhaeuser Way South. • Adding a bus shelter on the west side of Weyerhaeuser Way South. Project Limits This roundabout project extends improvements approximately 300 feet (ft) from the center of the intersection on all three legs of the existing intersection. This will provide a smooth transition to existing roadways. Wetland A, a category II wetland, was identified adjacent to the west of the proposed project. Project Impacts The existing roadway already impacts the wetland buffer and the project will have temporary and permanent wetland buffer impacts. Soils outside of the existing gravel areas that are temporarily disturbed 11/3/11 YA11871002.020\R1344 and Weyer Wetland Delineafiondocx DRAFT 11 from the intersection improvements will be regraded to their original condition and revegetated with native plantings. There will be 6,536 square feet (ft-2) of new buffer impacts at the southern end of the site from the roundabout installation and the sidewalk, lighting and landscaping improvements. The project has been designed to avoid all impacts to the wetland area or wetland functions. The Federal Way Revised Code (FWRC) allows public roads within wetland buffers [FWRC 19.17.040(3)] provided there is no feasible alternative. 11/3/11 YA118T002.020\R%344 and Weyer Wetland Delineation.doex iii DRAFT Site Information Location Site Name(s) County City Section (1A, 1/4), Township, Range Latitude, Longitude Watershed WRIA Number of Designation: Type within Study Area (Cowardin/HGM): FACTSHEET Information South 344"' Way at Weyerhaeuser Way South Improvements King Federal Way Section 21, Township 21 North, Range 04 East 470 17' 31"N, 1220 17' 33'W Puyallup/White 10 ig, wetland type, wetland functions, buffer width, and wetland size: Category Water Hydrologic Habitat Buffer (Rating): Quality Rating Rating Width: Rating Wetland A PFO-PSS/depressional II (57) 32 7 Key: PFO — Palusline forested PSS—Paiustinescmb-shrub * Size based on delineated wetland area and estimated boundary outside of project area.

The project purpose is improving intersection operations by installing a two-lane roundabout. New sidewalks, roadway illumination and landscaping will improve the safety and aesthetic character at the intersection. Proposed Improvements for the intersection of South 3441h Way at Weyerhaeuser Way South include: ■ Roadway widening, as required for constructing a two-lane roundabout + Installing curb, gutter, and sidewalk along both sides of the roadway + Potentially adding retaining walls to mitigate impacts to private property and/or sensitive areas + Upgrading stormwater collection, treatment, and detention facilities • Installing a new roadway illumination system • Installing planter strips along both sides of the roadway and landscaping within the roundabout ■ Moving the existing bus shelter on the east side of Weyerhaeuser Way South. ■ Adding a bus shelter on the west side of Weyerhaeuser Way South. This project extends improvements approximately 300 ft from the center of the intersection on all three legs of the existing intersection. This will provide smooth transitions to existing roadways. 1.1 SITE DESCRIPTION The project is located in the City of Federal Way at the intersection of South 344th Way and Weyerhaeuser Way South, within the Puyallup/White watershed [Water Resource Inventory Area (WRIA) 10] in Section 21, Township 21 North, and Range 4 East. Existing land uses in the area include Highway 18 to the north and undeveloped forested area to the south with residential development further south. There is a business park on the east side of the intersection and forested land owned by Weyerhaeuser on the west side of the intersection and within the project vicinity. The project location is shown on Figure 1. 11/3/11 Y:\1187\002.020\R\344 and Weyer WeUand DelineaBorndocx 1-1 DRAFT 1.2 REGULATORY BACKGROUND The Clean Water Act (CWA) requires authorization for the discharge of dredged or fill material into the "waters of the U.S." under Section 404. FWRC contains requirements for establishing wetland buffer widths and building setbacks for any alteration, including fill, of wetlands and their buffers. The Washington State Department of Ecology (Ecology) requires compliance with the State Water Pollution Control Act (RCW 90.48), and it has administrative oversight of Section 401 of the CWA for water quality certification in the case of impacts to U.S. Army Corps of Engineers (USACE) jurisdictional "waters of the U.S." Any work that will use, divert, obstruct, or change the bed or flow of state waters, including streams and rivers, must obtain Hydraulic Project Approval (HPA) issued by the Washington Department of Fish and Wildlife (WDFW). WDFW HPA is administered under RCW 77.55 and rules in WAC 220-110. Wetlands and certain waterways are regulated by federal, state, and local governmental agencies and compliance with one agency does not necessarily fulfill permitting requirements of any other agencies. In this instance, the wetland area was delineated and it was determined only minor impacts will occur to the wetland buffer. No fill will be placed into waters and no water will be diverted. For this project, the City has requirements for establishing wetland buffer widths and building setbacks, as well as for any alteration, including fill, of wetlands and their buffers. The FWRC allows public roads within wetland buffers [FWRC 19.17.040(3)]) provided there is no other feasible and reasonable alternative. 11/3/11 YA118A002 020\R\344 and Weyer Wetland Delineation docx 1-2 DRAFT 2.0 METHODS Landau Associates did this wetland investigation in compliance with the USACE Wetland Delineation Manual (USACE 1987), the USACE Regional Guidance letter on the 1987 Manual (USACE 1994), and the USACE Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Regional Supplement) (USACE 2010). As of March 1, 2011, Ecology has adopted USACE's Regional Supplement for wetland investigations. Therefore, Ecology's Washington State Wetlands Identification and Delineation Manual (Ecology 1997) was not applied. In general, the USACE and Ecology recommend gathering preliminary data and synthesizing available background information, followed by a field investigation. 2.1 BACKGROUND INFORMATION REVIEW Landau Associates reviewed the following public domain resources to determine existing conditions and potential wetlands and other "waters of the U.S." within the study area: • Topographic map [image data source: U.S. Department of Agriculture (USDA), 1999] ■ Aerial photograph (image data source: I3 Imagery Prime, 2009) • National Wetlands Inventory (NWI) map [Image data source: U.S. Fish and Wildlife Services (USFWS), 2010] • Federal Emergency Management Agency (FEMA) GIS data Flood Map (image data source: FEMA, 2011) • USDA National Resources Conservation Service (MRCS) Web Soil Survey (image data source: USDA 2006) • National Hydric Soils List (USDA, NRCS website 2011) • City of Federal Way Critical Areas Map (Federal Way 2008) • Precipitation data [USDA NRCS website 2002, National Climatic Data Center, (NCDC) 2011]. 2.2 WETLAND DELINEATION Both USACE and Ecology outline a three -parameter approach to determine the presence or absence of wetlands that requires evaluating vegetation, soil, and hydrology (Table 1). Landau Associates' biologists completed the field delineation using the routine onsite method, where data are collected at locations representative of typical wetlands and/or uplands of the study area. Following this method, an area is determined to be wetland if each of the following three criteria are met (also see Table 1): • The dominant vegetation is hydrophytic 11/3/11 YA1187\002.020kR\344 and Weyer Wetland Dellneation.dou 2-1 DRAFT * Soils are hydric ■ Wetland hydrology is present. "Difficult wetland situations" may occur in which one or more of the required criteria have been disturbed by human or natural events (atypical situations) or are absent due to natural variability (problem area). In cases of difficult wetland situations, a wetland determination can be based on the best available information of the site, knowledge of the ecology of wetlands in the region, and/or the other undisturbed/ present criteria. 2.3 WETLAND CLASSIFICATION, RATING, AND BUFFER WIDTH Any wetlands identified as part of this project were classified according to the USFWS' Cowardin classification system (Cowardin et al. 1979) and the USACE's hydrogeomorphic (HGM) classification system (Brinson 1993). Wetlands were rated according to the Washington State Wetlands Rating System for Western Washington (Hruby 2004), and classified under the FWRC Section 19.175.020. This system categorizes wetlands based on their existing functions including: water quality, hydrology, and habitat, as well as the wetland's rarity, sensitivity to disturbance, or inability to replace. Wetland buffers were determined according to FWRC Section 19.175.020. 1113/11 YA1187\002 020\R\344 and Weyer Wetland Delineation docx 2-2 DRAFT 3.0 RESULTS This section provides the results of the background information review and field investigation. 3.1 BACKGROUND INFORMATION REVIEW Wetlands The U.S. Geological Survey (USGS) topographic map for the project area (Appendix A, Figure A-1) identifies the intersection of South 344"' Way and Weyerhaeuser Way South. The area surrounding it is shown as undeveloped vegetated area. The terrain is relatively flat. The USGS topographic map does not identify any wetlands, streams, depressions, or water features in the project area. The aerial photograph (Appendix A, Figure A-2) shows the intersection of South 344"' Way and Weyerhaeuser Way South. The area to the west of Weyerhaeuser Way South is forested. The area to the east is a developed business park with Highway 18 to the north and undeveloped forested area to the south and then residential development. No streams or water features are identifiable within the project area. The National Wetlands Inventory Map (Appendix A, Figure A-3) identifies one large wetland complex within and adjacent the project area to the west of intersection of 344"' Way and Weyerhaeuser Way South. The wetland area within the project area is shown as a palustrine, scrub -shrub, seasonally flooded (PSSC) and palustrine, forested, seasonally flooded (PFOC) wetland. Floodplains The FEMA flood map (Map 53033CI250 F, Map revised May 16, 1995 Panel 1250) does not show any flood zones within the project area (FEMA 2011). Additionally, the 2011 FEMA GIS data (Appendix A, Figure A-4) does not show any flood hazards within the project area or surrounding area. Soils The USDA NRCS Web Soil Survey identifies two soil series within the project area (Appendix A, figure A-5; complete soil profile reports are provided in Appendix B): Alderwood gravelly sandy loam, 0 to 6 percent slopes (AgB) consist of moderately deep to a cemented pan, moderately well drained soils formed in glacial till (USDA, NRCS 2007a). The typical profile generally consists of gravelly sandy loam from 0 to 12 inches below ground surface (BGS) over very gravelly sandy loam to 60 inches BGS (USDA, NRCS 2011). A perched water table can be found in these soils as high as 18 to 36 inches from January through March (USDA, NRCS 2007a). The National Hydric Soils List (USDA, NRCS website 2011) lists Alderwood gravelly sandy loam, 0 to 6 percent slopes as a hydric 11/3/11 Y:\1187\002.020\R\344 and Weyer Wetland Delineafion.docx 3-1 DRAFT soil in depressions that contain components of the Norma, Bellingham, Tuckwilla, Shalcar, Buckley soil series. • Shalcar muck (Sm) consist of very deep, very poorly drained soils formed in herbaceous and woody organic deposits overlying alluvium, glacial outwash, or glaciomarine deposits (USDA, NRCS 2007b). The typical profile generally consists of muck from 0 to 14 inches BGS over fine sandy loam from 14 to 18 inches BGS then loamy sand from 28 to 60 inches BGS (USDA, NRCS 2011). An apparent high water table can be as high as soil surface level to one foot over the soil surface at times between October through May (USDA, NRCS 2007b). The National Hydric Soils List (USDA, NRCS website 2011) lists Sahalcar muck as a hydric soil in depressions that contain components of the Shalcar, Tuckwila, Seattle, Norma, Puget, Snohomish soil series. Critical Areas The City of Federal Way Critical Areas Map (Appendix A, Figure A-6) identifies a small wetland within the project area located west of the intersection of South 344 h Way and Weyerhaeuser Way South. No other streams or water features are identified within the project area on the Federal Way Critical Areas Map. Precipitation Precipitation data for the three month period prior to the field investigation in the Puget Sound Lowlands (NCDC 2011) indicate recorded precipitation levels were above the normal range for the months of April, May, and June as listed in NRCS Wetlands Determination (WETS) tables (USDA, NRCS website 2002) (Appendix C) and as shown in the table below: Normal (a Lower Limit Upper Limit Month Year of Normal of Normal Recorded b April 2011 1.71 3.11 4.68 May 2011 1.16 June 2011 0.96 (a) USDA NRCS 2002 (b) NCDC 2011 2.13 4.10 1.79 2.43 3.2 FIELD INVESTIGATION Landau Associates project scientist, Jessica Stone, and project manager Theresa Turpin conducted field investigations on July 13, 2011. This time period was within of the official growing 11/3/11 Y1118AO02.020%R%344 and Weyer Wetland Delineatlon docx 3-2 DRAFT season recognized by the Seattle District USACE (1994). The weather during the July site investigation was in the low 70s, partly cloudy with scattered showers. Sampling points were taken in areas suspected to meet the mandatory wetland criteria and nearby upland to determine corresponding wetland/upland boundaries. An upland sampling point and a wetland sampling point were flagged and recorded by the survey crew and are shown on Figure 2. The wetland boundary was delineated using numbered flagging. The boundary of one wetland was delineated and boundaries extending off site were estimated based on aerial photographs, since survey data was unavailable. Site observations and existing background information including detailed information on soils, vegetation, and hydrology from the sampling points is provided on the completed data sheets in Appendix D. Site photographs are provided in Appendix E. The wetland rating information is included in Appendix F. 3.2.1 WETLAND A Wetland A is approximately 37,714 ft2 (0.9 acre), approximately 320 ft2 of which was delineated along the right-of-way (ROW) adjacent to Weyerhaeuser Way South. The entire boundary of Wetland A was walked to estimate its size, conduct a wetland rating, and to determine any other wetland connections. Wetland A is identified on the NWI map as a PSSC wetland, the City of Federal Way Critical Areas Map, and the USDA Soils Map identify this area as containing Shalcar muck, a hydric soil (Appendix A, Figure A-3, A-5 and A-6). Sampling point SP-01 was recorded to describe the wetland and is located at its eastern edge in the Weyerhaeuser Way South ROW. One upland sampling point; Sampling Point SP-02 is located between the wetland and Weyerhaeuser Way South near Sampling point SP-01. 3.2.1.1 Vegetation Wetland A is dominated by hydrophytic vegetation, primarily forested vegetation along the wetland's edge, and scrub -shrub within the wetland's interior. The dominant plant species observed within sampling point SP-0I include: • Spirea (Spiraea douglasii, FACW) ■ Red alder (Alnus rubra, FAC). Additional non -dominant species include Pacific willow (Salix lasiandra, FACW) and Scouler willow (Salix scouleriana, FAC). Other dominant species identified within the wetland but outside of the sampling point include salmon berry (Rubus spectabilis, FAC) and slough sedge (Carex obnupta, OBL). 11/3111 YA11071002.020\R\344 and Weyer Wetland Delineabon.docx DRAFT 3-3 3.2.1.2 Soils The soils in sampling point SP-01 are characterized as loamy mucky mineral (hydric soil indicatory F1). From 1 to 12 inches BGS the soils were black (IOYR 2/1) saturated silty muck with dark brown (7.5YR 3/2) redox features. This is consistent with the USDA soils map which identifies this area as containing Shalcar muck (Appendix A, Figure A-5). 3.2.1.3 Hydrology The primary indicators of wetland hydrology observed at sampling point SP-01 are a high water table (indicator A2), saturation (indicator A3), algal mat or crust (indicator 134), and water -stained leaves (indicator 139). Wetland A receives its hydrology from perched groundwater over glacial till and from surface water runoff from the surrounding upland and Weyerhaeuser Way South. 3.2.1.4 Wetland Determination All three mandatory wetland criteria are satisfied for Wetland A. Landau Associates classified Wetland A as a PFO-PSS/depressional (Cowardin/HGM classification) wetland. The USFWS National Wetlands Inventory (NWI) Map shows Wetland A to be connected to a forested wetland complex (Appendix A, Figure A-3), however, Wetland A is an isolate depression surrounded by dense Douglas -fir (Pseudotsuga menziesii) and salal (Gaultheria shallon) upland. There were no potential wetland connections or adjacent wetlands identified. The section/range/township of the project area is listed by the National Heritage Program as containing rare plants and/or high quality native ecosystems and wetlands [Washington State Department of Natural Resources (DNR) 2011]. However, a data review conducted by the DNR concluded that there are no records of occurrences in the vicinity of the project area (DNR letter, Appendix F). Using the Ecology wetland rating form, Wetland A is rated as a Category II wetland with a total score of 57. Wetland A scored highest for water quality functions with a score of 32. Hydrologic functions received a score of 7 and habitat functions received a score of 18. The FWRC section 19.175.020, wetlands categories and standard buffers, classifies regulated wetlands into three categories (Category I, Category II, and Category III). Wetland A does not meet the criteria for a Category I wetland as it does not: • Contain the presence of species or documented habitat recognized by state or federal agencies as endangered, threatened or potentially extirpated plant, fish or animal species; or • Contain the presence of plant associates of infrequent occurrence, irreplaceable ecological functions, or exceptional local significance including but not limited to estuarine systems, peat bogs and fens, mature forested wetlands, groundwater exchange areas, significant habitat or unique educational sites; or 11/3/11 YA1187\002.020\R\344 and Weyer Wetland DelineaBondocx 3-4 DRAFT • Have three or more wetland classes, one of which is open water. Category II wetlands are categorized as being greater than 2,500 ft2 in area, do not exhibit the characteristics of Category I wetlands, and meet one of the following criteria: • Are contiguous with water bodies or tributaries to water bodies which under normal circumstances contain or support a fish population, including streams where flow is intermittent; or • Are greater than one acre in size in its entirety; or • Are less than or equal to one acre in size in its entirety and have two or more wetland classes, with neither class dominated by nonnative invasive species. Wetland A is not contiguous with any water bodies or tributaries and based on estimation not greater than one acre in size, however, Wetland A consists of two Cowardin vegetation classes: forested and scrub -shrub, neither of which are dominated by non-native or invasive species. Therefore, Wetland A, in accordance with the FWRC, is a classified as a Category II wetland which requires a 100-ft buffer. 3.2.1.5 Upland Characterization Much of the Wetland A buffer is located within the existing Weyerhaeuser Way South and ROW. The upland area adjacent to Wetland A is characterized by sampling point SP-02 which did not satisfy all of the three mandatory wetland criteria (see Figure 2 and Appendix D). Sampling point SP-02 is located within the ROW of Weyerhaeuser Way South and the edge of Wetland A (Figure 2). The upland area surrounding Wetland A was also traversed. No wetland hydrology indicators were observed within the upland sampling point adjacent to Wetland A or within the upland area surrounding Wetland A. Due to the proximity between Wetland A and Weyerhaeuser Way South, some hydrophytic vegetation extended to the roadside. However, sampling point SP-02 was dominated by forested upland and understory vegetation. Dominant vegetation at sampling point SP-2 consisted of: • Douglas -fir (Pseudotsuga menziesii, FACU) ■ Red alder (Alnus rubra, FAC) • Salal (Gaultheria shallon, FACU). Additional non -dominant species at sampling point SP-2 include Pacific willow (Salix lasiandra, FACW), Scouler willow (Salix scouleriana, FAC), Douglas spirea (Spiraea douglasii, FACW), trailing blackberry (Rubus ursinus, FACU), sword fern (Polystichum munitum, FACU), and nootka rose (Rosa nutkana, FAC). The uplands surrounding the eastern side of Wetland A are dominated by Douglas -fir and salal. 11/3/11 YA118T002020%RN344 and Weyer Wetland Delineatiortdocx DRAFT 3-5 During the field investigation, the soil within the upland sample point SP-02 was dry. The soils contained a thick layer of duff from 0 to 3 inches, below were brown (1 OYR 4/3) loamy sand from 3 to 12 inches BGS and, from 12 to 13 inches BGS, the soils were light olive brown (2.5Y 5/3) very dense, gravelly sand. The depth of the sample pit could not be excavated deeper due to this very dense layer. No hydric soil indicators were observed in the upland sampling point. 1113/11 YA1187\002.020\R\344 and Weyer Wetland Delineabon.dou 3-6 DRAFT 4.0 PROJECT IMPACT ASSESSMENT AND MITIGATION The project purpose is to improve the intersection operations by replacing the existing three legged T-intersection with a two-lane, three legged roundabout. New sidewalks, roadway lighting, and landscaping are planned which will also improve the safety and aesthetics of this intersection. 4.1 AVOIDANCE/MINIMIZATION The proposed project is an intersection improvement; installing a roundabout, including sidewalks, lighting, and native landscaping compatible with surrounding vegetation. The project will improve safety and intersection functions. The western portion of the Wetland A buffer is permanently impacted due to the paved portion of Weyerhaeuser Way South being located within the 100-ft buffer area. The proposed project, installing the roundabout and road improvements, will not impact, nor reduce any of the wetland functions or values. Additionally, there will not be a significant reduction to the wetland buffer's functions and values since the buffer is already impacted by the existing roadway. Stormwater improvements will be constructed for the intersection improvements to meet flow control and water quality requirements. The improvements will incorporate natural drainage practices, including bioretention and porous sidewalks, to the extent feasible. Stormwater that cannot be infiltrated will be detained and treated through conventional methods (i.e., underground pipes/chambers and cartridge filters) in compliance with stormwater requirements. There will be no additional stormwater discharge into the wetland area. The proposed project will not adversely affect water quality, wetland or buffer habitat, drainage or stormwater capabilities, nor cause unstable earth conditions or erosion hazards. 4.2 UNAVOIDABLE IMPACTS The roundabout design will impact the existing buffer of Wetland A. Currently much of the eastern portion of the existing Wetland A buffer is within the paved portion of Weyerhaeuser Way South. The roundabout and associated lighting, landscaping, sidewalks and bike lane will impact 6,536 ft2 of the wetland buffer at the southern end of the site. 4.3 MITIGATION Soils outside of the existing gravel areas that are temporarily disturbed from the intersection improvements will be regraded to their original condition and revegetated with native plantings. All revegetation will be inplace and will not extend beyond the temporarily disturbed areas. 11/3/11 Y:\1187\002.020\R\344 and Weyer Wetland Delineation.docx M DRAFT As stated earlier, The FWRC provides an exemption for public roads within wetland buffers [FWRC 19.17.040(3)1: Essential public facilities, public utilities and other public improvements. The director of community development may permit the placement of an essential public facility, public utility or other public improvements in a regulated wetland buffer if he or she determines that the line or improvement must traverse the buffer because no feasible or alternative location exists based on an analysis of technology and system efficiency. The specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. The proposed project is an essential public improvement designed to improve the public roadway by providing safety improvements at the intersection of South 344"' Way and Weyerhaeuser Way South. The proposed project has been designed specifically to avoid all wetland impacts; there is no feasible alternative location for the intersection roundabout with less impact. 11/3111 YA1187\002.020\R\344 and Weyer Wetland DelineaUondocx 4-2 DRAFT 5.0 USE OF THIS REPORT These findings are based on our understanding of the FWRC, the USACE, and Ecology wetland delineation methodology, and on our interpretation of the vegetative, soil, and hydrology conditions observed during the site reconnaissance on July 13, 2011. Within the limitations of scope, schedule, and budget, the findings presented in this report were prepared following generally accepted sensitive area investigation principles and practices in this locality at the time the report was prepared. We make no other warranty, either express or implied. This report was prepared for the use of TetraTech/INCA, the City, and applicable regulatory agencies. No other party is entitled to rely on the information, conclusions, and recommendations included in this document without the express written consent of Landau Associates. Further, the reuse of information, conclusions, and recommendations presented for extensions of the project or for any other project, without review and authorization by Landau Associates, shall be at the user's sole risk. Wetland areas delineated by Landau Associates are considered preliminary until the USACE and/or local jurisdictional agencies validate the wetland boundaries. Because wetlands are dynamic communities, wetland boundaries may change over time. The agencies typically recognize wetland delineations for a period of five years following an approved jurisdictional determination. In addition, changes in government code, regulations, and/or laws may occur. This document has been prepared under the supervision and direction of the following key staff. LANDAU ASSOCIATES, INC.

TYPE LOCATION: Snohomish County, Washington; about 5 miles east of Lynnwood on Maltby road; 200 feet south and 400 feet east of the center of sec. 28. T. 27 N., R. 5 E. RANGE IN CHARACTERISTICS: The mean annual soil temperature is estimated to range from 47 to about 55 degrees F. These soils are usually moist, but are dry between depths of 8 and 24 inches for 60 to 75 consecutive days in the summer in most years. The soil is strongly acid to slightly acid above the 2Cd1 horizon and slightly acid or moderately acid in the 2Cd1 horizon. Depth to 2Cd1 horizon is 20 to 40 inches. Rock fragments in the particle -size control section range from 35 to 50 percent total including 35 to 50 percent gravel and 0 to 10 percent cobbles. The A horizon has hue of 1 OYR or 7.5YR, value of 2 or 3 moist, 3 through 5 dry, and chroma of 2 to 4. It has weak or moderate granular structure. Some pedons have an E horizon less than 1 inch thick. The BwI and Bw2 horizons have hue of 1 OYR or 7.5YR, and value and chroma of 2 through 6 dry or moist. It is very gravelly loam or very gravelly sandy loam and has weak or moderate blocky structure. The Bwl is gravelly loam in some pedons. This horizon contains none to many hard concretions presumed to be of iron and manganese compounds. The 213g horizon, or the 213C or 2CB horizon has hue of 1 OYR or 2.5Y, value of 5 through 7 dry, and chroma of 2 through 4 moist and dry. They have redox concentrations in some pedons, but lack depletions of 2 or lower chroma within 30 inches of the surface. These horizons are very gravelly sandy loam or very gravelly loam. They have weak subangular blocky structure or are massive. The 2Cd horizons (densic layers) have hues of 1 OYR or 2.5Y, value of 4 through 8 dry, and chroma of 1 through 3 moist and dry and are mottled in some pedons. It is very gravelly sandy loam, very gravelly loamy sand, gravelly sandy loam, or gravelly loamy sand when crushed. COMPETING SERIES: These are the Baldhill, Neausite, Dabob, Fidalgo, and Whistle series. The Baldhill soils are very deep and lack densic materials. The Beaustie and Fidalgo soils are 20 to 40 inches deep to a lithic contact. The Whistle soils are 40 to 60 inches deep to a lithic contact. Dabob soils have an albic horizon and lack densic materials within 60 inches. GEOGRAPHIC SETTING: These soils are on till plains and moraines at elevations of 0 to about 800 feet. Slope is 0 to 65 percent. The soils formed in glacial till. Alderwood soils are in a cool marine climate. The summers are cool and dry, and the winters are mild and wet. Mean annual precipitation ranges from 25 to 60 inches, most of which falls as rain from November through March. Mean January temperature is 38 degrees F, mean July temperature is 60 degrees F, and mean annual temperature is 50 degrees F. The growing season (28 degrees F) is about 200 days. GEOGRAPHICALLY ASSOCIATED SOILS: These are the Beausite, Dick, Everett, Hoogdal, Indianola, Kitsap, Norma, Quilcene, Skipopa and Whidbey series. All of these soils except Whidbey soils lack a densic layer within 40 inches. In addition, the Beausite soils have a lithic contact at 20 to 40 inches. Dick, Hoogdal, Indianola, Kitsap, and Skipopa soils have less than 35 percent coarse fragments. Everett soils are sandy -skeletal. McKenna soils have an aquic moisture regime. Norma soils have an aquic moisture regime of less than 35 percent coarse fragments in the upper part of the control section. Quilcene soils are in a fine family. Whidbey soils have an E horizon 2 to 5 inches thick and have a higher base status. DRAINAGE AND PERMEABILITY: Moderately well drained; slow to medium runoff; moderately rapid permeability to the densic layer and very slow permeability below. A perched water table is as high as 18 to 36 inches at times from January through March. USE AND VEGETATION: Used mostly for woodland, field crops, hay and pasture, orchards, vineyards, wildlife habitat, watershed, and non -farm uses. The native vegetation is Douglas -fir, western hemlock, western redcedar, and red alder with an understory of salal, Oregon -grape, western brackenfern, western swordfern, Pacific rhododendron, huckleberry, red huckleberry, evergreen huckleberry, and Orange honeysuckle. DISTRIBUTION AND EXTENT: Northwestern Washington; MLRA 2. The series is extensive. MLRA OFFICE RESPONSIBLE: Portland, Oregon SERIES ESTABLISHED: Snohomish County, Washington 1936. REMARKS: Classification only changed 4/94 because of recent amendments to Soil Taxonomy, except the horizon nomenclature was updated, and fragments of ortstein and ortstein were changed to iron-mangenese nodules and a densic layer. Classification changed 1/2000 from mixed, mesic Vitrandic Durochrepts to isotic, mesic Vitrandic Dystroxerepts based on revision to Soil Taxonomy. Diagnostic horizons and features include: Ochric epipedon Cambic horizon - from 7 to 35 inches Densic material - from 43 to 60 inches Vitrandic feature - assumed to be from 0 to 30 inches Oxyaquic feature - perched water table at 18 to 36 inches at times from January to March. All depths to diagnostic horizons and features noted in the range of characteristics are measured from the top of the first mineral horizon. More investigation is needed to differentiate the Alderwood from the Dabob series. ADDITIONAL DATA: Partial data available for this series. Sample # S71 WA-033-002, Riverside Lab., 11/73.

Depth to mineral soil - 16 to 51 inches Fiber content - 5 to 40 percent (2 to 15 percent rubbed) Oa horizons Hue - 2.5YR to 2.5Y, or N Value - 2 to 4 moist, 2 to 5 dry Chroma - 1 to 3 moist and dry Reaction - extremely acid to moderately acid Wood fragments - 0 to 10 percent 2Bg horizon Hue - 1 OYR to 5Y, 5GY, or N Value - 3 to 5 moist, 5 to 8 dry Chroma - 1 or 2 moist and dry Reaction - moderately acid or slightly acid Texture - SIL, SL, L, or SCL 2Cg horizon Hue - 5Y, 5GY, or N Value - 4 or 5 moist, 5 to 7 dry Reaction - moderately acid to neutral Texture - S, LS, SL, L, SIL, or SICL Coarse fragments - 0 to 60 percent gravel COMPETING SERIES: These are the Klossner, Linwood, Medo, Natchaua, Palms, and Philbon series. Linwood soils formed in predominately woody fiber. Klossner, Natchaug, and Palms soils occur in a continental climate with more than 26 degrees F difference between mean January and July soil temperatures. Medo soils are slightly acid to slightly alkaline in the organic horizons. Philbon soils are neutral to moderately alkaline in the organic horizons. GEOGRAPHIC SETTING: Shalcar soils are in depressional areas on stream terraces, and outwash terraces of drift plains. Elevation is 0 to 700 feet. Slopes are 0 to 2 percent. These soils formed in herbaceous organic deposits overlying alluvium, glacial outwash, or glaciomarine deposits. The climate is characterized by warm dry summers and mild moist winters. Snow cover is intermittent. Mean annual precipitation is 18 to 55 inches. Mean January temperature is 36 degrees F; mean July temperature is 62 degrees F. Mean annual temperature is about 50 degrees F. The frost -free period is 150 to 190 days. GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bellingham, Fishtra , Kickerville, Norma, Pangborn, Seattle, and Sumas soils. Bellingham and Norma soils occur in depressions but are poorly drained Inceptisols. Fishtrap soils are Histosols and occur in depressions as well but are sandy or sandy -skeletal in the particle -size control section. Kickerville soils are on outwash terraces and plains but are well drained Spodosols. Pangborn and Seattle soils are Histosols and occur in depressions but are more than 51 inches deep to mineral soil. Sumas soils are on floodplains and are poorly drained Entisols. DRAINAGE AND PERMEABILITY: Very poorly drained; Permeability is moderate to the 2Cg horizon. Permeability of the 2Cg horizon ranges from very slow to very rapid. An apparent high water table is as high as the surface to 1 foot over the surface at times from October through May unless drained. USE AND VEGETATION: Most Shalcar soils have been cleared and drained and used for pasture, hay, and some for cropland. The potential natural vegetation is mainly Douglas spirea, skunk cabbage, Pacific willow, and slough sedge. Some areas have an overstory of red alder, western hemlock, Sitka spruce, and lodgepole pine. DISTRIBUTION AND EXTENT: Western Washington, west of the Cascade Mountains; MLRA 2. The series is of moderate extent. MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland, Oregon SERIES ESTABLISHED: Grays Harbor Area, Washington, 1970. REMARKS: Diagnostic horizons and features recognized in this pedon include: Histic epipedon - the zone from 0 to 37 inches (Oa horizons) Terric feature - the zone from 37 to 60 inches (213g and 2Cg horizons) Particle -size control section - 37 to 51 inches (213g horizon) Histosols control section - the zone from 0 to 51 inches (Oa horizons and part of the 213g horizon) Thin discontinuous layers of volcanic ash and diatomaceous earth (1/2 to 2 inches thick) occur between 24 and 48 inches in some pedons.

For the purposes of this rating system, "documented" means the wetland is on the appropriate X state or federal database. SP2. Has the wetland unit been documented as habitat for any Slate listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note. Wetlands with State listed plant species X are categorized as Category 1 Natural Heritage Wetlands see p. 19 of data form). SP3. Does the wetland unit contain individuals o Priorityspecies listed by the WDFW or the stale? X SP4. Does the ivetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or X in a local mana ement plan as having special significance. To complete the next M of the data sheet you will need to determine the HydrogeomoEphic Class of the wetland being rated. The hydrogeomorphic classification groip wetlands in to those thaafum Lion in similarways. This simplifies the questions needed to answer how well the y4eland fursctfor& The HydrogemwThicClass ofa wetland can be determined using the key below. See p.24 for more detailed instrmc ns an classifying wetlands. Wetland Rating Form — western Washington, version 2 (7/06) Page 1 of 9 Wetland name or number: Wetland A Classification of Vegetated Wetlands for Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. I. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO - go to 2 YES - the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; At least 30% of the open water area is deeper than 6.6 (2 m)? NO -go to 4 YES - The wetland class is Lake -fringe Lacustrine Fringe) 4. Does the entire wetland meet all of the following criteria? The wetland is on a slope (slope can be very gradual). The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than I foot deep). NO - go to 5 YES - The wetland class is Slope 5. Does the entire wetland meet all of the following criteria? The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river. The overbank flooding occurs at least once every two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding.. NO - go to 6 YES - The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. No - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area.

Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 — 2.0m (0.5 — 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages.

Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi -enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low -energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean -derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and _ may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).
