Jones Associates, Inc. (June 7, 2018) and received on September 7, 2018. The department's consultant, Otak, Inc., was asked to provide an estimate to review this report. The normal course of action is for the city to set up an account to be funded by the applicant and drawn down by the work performed by Otak. If any of the funds are not used, they will be returned to the applicant. Please make check in the amount of $4,200.00, payable to the City of Federal Way, and sign the enclosed task authorization form. The city's consultant will begin their review on the applicant signature and fee payment. This fee will cover the review of the submitted materials, a site visit, and technical memorandum(s). Additional reviews or meetings beyond that will require a supplemental cost and authorization. CRITICAL AREA ALTERATIONS PROHBITED The department is aware of work performed on the abovementioned site, which exceeds the scope of the demolition permit, city file no. 18.103551-00-DE, issued on August 8, 2018. Activities documented by the city's Code Compliance Division in September 2018, include vegetation, clearing, grubbing and earthwork including the compaction of soil by heavy machinery on or within 225 feet of a regulated wetland and stream. When a critical area or its buffer has been altered, all ongoing development work shall stop and the critical area shall be restored. The city shall have the authority to issue a stop work order to cease all ongoing development work, and order restoration, rehabilitation, or replacement measures at the owner's or violator's expense to compensate for violation of provisions of this chapter. The site contains a wetland and a Major Stream with a 100-foot stream buffer, per the city's former stream classification system. Exact wetland and stream locations, buffers widths, and ratings/ 18-104201-00-AD Doc 1D. 78282 Yuriy Melnichuk Page 2 of 2 October 10, 2018 classifications are unknown at this time; until Otak completes the critical area review. Accordingly, please cease all development activities —no earthwork, vegetation removal, or development may occur on the subject property until the city's critical area review is finalized.

Jones Associates (June 7, 2018). The city forwarded your request to our wetland consultant, Otak, for review after receiving fees on October 18, 2018. On November 2, 2018, Otak completed a site visit, reviewed relevant documents, and prepared a technical memorandum (November 16, 2018) in which they concur with the J.S. Jones determination that a Category III wetland and Type Ns stream (extends off -site) exist on the subject property. The site contains a Category III Riverine wetland with a standard buffer of 60-feet, and a Type Ns stream with a 35-foot buffer. These features and their buffers are depicted in the report approximately; however, the wetland boundary and stream ordinary highwater mark must be surveyed/GPSed and flagged by a qualified professional at the time of a project proposal. When planning future development on this site, take into account Federal Way Revised Code (FWRC) 19.145.160, which states: "Unless otherwise provided, structures shall be set back'a distance of five feet from the edges of a critical area buffer. The following may be allowed in the building setback area: (1) Landscaping; (2) Building overhangs; and (3) Fences and railings six feet and less in height." WETLAND/STREAM BUFFER VIOLATION As noted in correspondence sent to you on October 10, 2018, it has come to the city's attention that clearing and grading work occurred in the stream and wetland buffer during a manufactured home demolition in August. Except as provided in FWRC 19.145.120, no development or improvements may be located within a regulated stream or wetland buffer per FWRC 19.145.470 and 19.145.440. Additionally, portions of the stream and wetland buffer vegetation were cleared within the areas identified in the critical areas report and confirmed by Otak, Planning, and Code Compliance Divisions. These critical areas buffers regulate the dispersion of stormwater runoff and the water quality in the stream and wetland. Pursuant to FWRC 19.145.060, "Unauthorized alteration and enforcement," when a critical area or its buffer has been altered in violation of Chapter 19.145 "Environmentally Critical Areas," development work shall stop and the critical area shall be restored by the property owner. Further, if any stream buffer clearing occurred in the past without city approval, then this activity must be brought into conformance using the provisions of the current critical areas ordinance (i.e., abatement). 18- 104201 -00-AD Doc. LD 78369 Yuriy & Lyubov Melinchuk Page 2 of 2 November 29, 2018 In order to evaluate the exact impacts to the site beyond the clearing limits and what restoration actions will be necessary to mitigate for the damage, we need the following information: 1. A written narrative of what actions occurred outside the scope of the demolition permit. 2. A plan provided to the Planning Division demonstrating how the mitigation plantings will provide stream/wetland buffer enhancement and replacement. 3. A restoration, plan :prepared by a qualified professional, with appropriate plant species and spacing, using the best available science and describe how the actions proposed will: i. Restore the stream/wetland's previous structure and function related to maintaining water quality and habitats; ii. Replicate the historic soil types and configuration; iii. Replant the critical area and buffers with native vegetation that replicates the removed vegetation on the site in species types, sizes, and densities. The historic functions and values should be replicated at the location of the alteration; and iv. Information demonstrating compliance with FWRC 19.145.140 (mitigation plan requirements). This restoration plan complying with FWRC 19.145.140 shall be submitted to the director. Please note that the city may, at the owner's expense, seek expert advice in determining the adequacy of the plan. CLOSING The city's review has concluded. When you apply for future permits, include a copy of this letter with your submittal. The critical areas, associated buffers, and building setbacks must be delineated on the site plan of any development application in conformance with FWRC 19.145.150.4 and 19.145.260. Restoration of the stream buffer must be completed as an approval condition of any future permits. Please also provide the city with a timeline of your development project by December 7, 2018; stream buffer restoration and wetland mitigation plantings must occur in the appropriate planting season. If you have questions regarding this letter, or regarding how to complete the form, please contact me at (253) 835-2644, or leila.willoughby-oakes@cityoffederalway.com.

(Otak) conduct a review of the Critical Areas Report -Wetlands and Streams of the Melnichuk Property prepared by J.S. Jones and Associates, Inc., dated June 7, 2018 for Parcel #7978800521. The applicant is proposing to remove an existing double -wide mobile home and construct a wood framed single-family residence on the subject property. The critical areas assessment was reviewed in accordance with Federal Way Revised Code (FWRC) Chapter 19.145 (Environmentally Critical Areas) Article III (Fish and Wildlife Habitat Conservation Areas) and Article IV (Wetlands). The subject property is located at 32830 201h Avenue S, Federal Way, King County. The parcel is located in Township 21 North, Range 04 East, Section 16 in Water Resource Inventory Area (WRIA) 10 (Puyallup -White).

Jones and Associates, Inc. identifies one unnamed stream and one wetland (Wetland A) on the subject property. The stream flows north to south between the roadway and structure on site and discharges to a culvert. The stream is classified as a non -fish bearing seasonal watercourse (Type Ns) and has a standard buffer width of XWer the Federal Way Revised Code (FWRC) 19.145.270.01(c) (2017). Wetland A is a riverine wetland loAt4bd on both sides of the stream bank and has a palustrine fares (PFO) habitat. Wetland A is rated Category III with a habitat score of 4 and has a standard buffer width o 60 et per FWRC 19.145.420(2) (2017). No other critical areas were identified on the subject property. The City's Critical Area Map identifies one stream flowing north to south on the subject property. No wetlands are mapped by the City. The Federal Way Stream Inventory New DNR Classifications map (2001) shows the unnamed stream intersecting the subject property. The stream is mapped as Type F (Fish habitat) downstream of the site. The findings of our review and site investigation are as follows: No stream is mapped on the subject property by the DNR Forest Practices Application Mapping Tool or WDFW's SalmonScape and Priority Habitat and Species databases. No stream or wetland are mapped on the subject property by USFS NWI maps. One stream (Stream A) and one wetland (Wetland A) were identified on the subject property. The subject property does not contain habitat with a primary association with state or federally listed species, habitat for state priority species, or habitats/species of local importance. No other critical areas were identified on the subject property. The majority of the property consists of disturbed upland with little to no vegetation —primarily as a result of clearing and grading. Stream A Stream A flows north to south near the western portion of the subject parcel. Stream A flows from off -site through a round metal culvert on an adjacent property to the north, and flows onto the subject property beneath a chain - link fence on the northern property border. Stream A discharges to a 4-foot diameter metal culvert that extends beneath the property's driveway and discharges off -site to the parcel to the south. The stream is constricted by both culverts on and off -site. The on -site downstream culvert is armored with riprap on the left bank and a short wood -post wall extends from the armor to the fence on the north end of the property. The stream segment on the subject property consists predominately of riffle habitat, with a pool upstream near the fence line. Stream substrate consists primarily of gravels with few cobbles and some angular rock material. No evidence of scour or wracking was observed, and stream banks appeared relatively stable. The floodplain is comprised of saturated soils dominated by a dense layer of English Ivy (Hedera helix). The stream buffer consists of Western red cedar (Thuja plicata), Douglas fir (Pseudotsuga menziesii), red alder (Alnus rubra), salmonberry (Rubus spectabilis), sword fern (Polystichum munitum), and disturbed areas such as the wood -post wall, chain - link fencing, and cleared areas. Stream A has an average width of 7 feet between the active channel banks, and evidence of depths of inundation ranging between 1.4 and 1.6 feet during substantial precipitation events. No large wood was noted on the subject Critical Areas Review — Melnichuk Property Page 3 November 16, 2018 property during the site visit, and no evidence of wracking or deposition of wood or debris was observed. Little evidence of sediment deposition was observed outside of the active channel, and the sediment staining of ivy leaves that was observed consisted of fine sediment deposited in limited portions of the adjacent riparian habitat. Impoundment of water outside of the active stream channel appears to be an infrequent event, and the downstream culvert on the subject property is apparently appropriately sized to convey most flows and debris loads in the Stream A system. We concur with J.S. Jones and Associates that Stream A is accurately typed as a Ns (non -fish bearing, seasonal) watercourse. Evidence of Type Ns is indicated by the dense ivy cover on the floodplain. Ivy is a facultative upland species and would likely not establish in a perennial flow regime with a consistent hyporheic hydrologic connection. Evidence of periodic lack of stream flow included substantial root masses in the stream channel, which would not occur in a perennially flowing system. At the time of the site visit, water was flowing at approximately 4 to 5 feet per second through the site and the culvert to the south, creating a potential velocity barrier to fish species. Per FWRC 19.145.270(01) Type Ns streams have a standard buffer width of 35 feet. Wetland A Wetland A is a riverine wetland located on both sides of Stream A. The east -west wetland edges extend to the wood -post wall and the toe of slope to the west. Wetland A is dominated by English ivy with a Western red cedar canopy and had saturated soils to the surface at the time of the site visit. Vegetation species and wetland rating questions differed slightly from the report and our review; however, these changes did not affect the overall wetland classification or rating provided by J. S. Jones and Associates. We concur with the wetland delineation and rating of Wetland A as a Category III wetland with 4 habitat points. Per FWRC 19.145.420(2) Wetland A has a standard buffer width of 60 feet. Buffer Conditions Vegetation within the stream and wetland buffers has been cleared and grading/ground disturbance activities were apparent during the site visit. The stream and wetland buffers contain two large western red cedars (Thuja plicata) but no other vegetation. Vegetation has been cleared to the edge of Wetland A. Wetland and Stream Buffer Functions Wetland and stream buffers provide largely similar but slightly different ecological functions. Wetland buffers are the vegetated, undisturbed habitat surrounding a wetland. Stream buffers are associated with the area along a stream channel, where aquatic stream habitat transitions into terrestrial habitat, known as riparian habitat. In the Pacific Northwest, more highly functioning stream and wetland buffers are generally associated with vegetated corridors alongside the stream or river in question, or with vegetated habitat surrounding. Typically, the broader the vegetated corridor (measured laterally from the edges of the stream) and the less disturbed the vegetative community is, the more ecological function provided to the stream itself. Similarly, the more vegetated and undisturbed habitat completely surrounding a wetland, the higher the value of wetland functions provided. Stream and wetland buffer functions have been categorized per best available science (BAS) primary scientific literature, scientific reviews, other investigations, and various white and gray papers over the course of the past two decades. The following are relevant riparian functions provided by riparian buffers, based on BAS, and will be evaluated for this project. Stream buffers: 1) Moderate temperatures —canopy provides shade to the adjacent stream system, typically 60-100% cover 2) Provide large woody debris (LWD)—large wood provides in -stream habitat complexity and pool formation 3) Provide organic matter —insects and vegetative detritus contribute to the food web in the stream system 4) Stabilize stream banks —riparian vegetation can resist erosion and input of bank soil/sediment as a result Critical Areas Review — Melnichuk Property Page 4 November 16, 2018 5) Control sediment inputs —riparian vegetation can act as a filter to settle out sediment from stormwater runoff 6) Regulate nutrient and pollutant inputs —riparian vegetation can settle out pollutant -laden stormwater, and also act to inhibit nutrients (nitrate -nitrites, phosphorus) through plant uptake, minimizing introduction of those compounds into the stream Wetland buffers: 1) Reduce rapid water level fluctuations in wetlands 2) Maintain and improve water quality by trapping and absorbing sediments, nutrients and pollutants before they reach the wetland. 3) Reduce stormwater erosion into wetlands and stabilize riparian areas. 4) Decrease wetland disturbance from activities in adjacent areas. 5) Provide food, cover, travel corridors and breeding areas for wildlife. For both stream and wetland buffers, diverse and dense vegetative communities are critical for providing these functions. Although previous buffer conditions were impacted by the presence of 20th Avenue S. to the west, the subsequent clearing of vegetation on the subject property has resulted In degradation of all of the buffer functions. Aerial photos from previous years show forested conditions and Wetland and stream buffer functions may be partially recovered by appropriate restoration planning and implementation. Stream and Buffer Restoration Per FWRC 19.45.060 for unauthorized alterations and enforcement, when a critical area or its buffer has been altered in violation of this chapter, all ongoing development work shall stop and the critical area shall be restored. With respect to the subject property, FWRC 19.45.060 2(a) provides relevant requirements for restoration: (iii) The critical area and buffers shall be replanted with native vegetation that replicates the vegetation historically found on the site in species types, sizes, and densities. The historic functions and values should be replicated at the location of the alteration; and (iv) Information demonstrating compliance with FWRC 19.145.140 (Mitigation plan requirements) shall be submitted to the director A mitigation and monitoring plan will be required for restoration on the subject property.

S. Jones and Associates, Inc. 1.0 Project Description The applicant proposes to replace a double -wide mobile home and construct a wood framed single-family residence on the subject property. This study was conducted to determine the type and extent of wetlands and streams on or near the subject properties. 2.0 Site Address, Identification, and Directions The property is located at 32830 20th Avenue South, Federal Way, Washington 98003 (see attached Vicinity Map). The tax parcel number is 797880-0521. The property is in the southwest quarter of Section 16, Township 21 North, Range 04 East, of the Willamette Meridian. Directions to the site from Federal Way City Hall are as follows: Head Southeast on 81h Avenue South; drive for 0.2 miles; turn right on 9th Avenue South; drive for 0.1 miles; turn left onto South 336th Street; drive for 0.7 miles; turn right onto 20th Avenue South; the property is on the right side of the street in 0.4 miles. 3.0 Methodology The wetland assessment and delineation were performed using the Routine Determination methodology as described in Part IV, Section D of the Corps of Engineers Wetlands Delineation Manual (COE, 1987), the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (COE, 2008), and the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). The regional supplement is designed for use with the current version of the Corps Manual and all subsequent versions." Where differences in the two documents occur, and there are significant differences, the Regional Supplement takes precedence over the Corps Manual (COE, 2008). The wetland was rated using the Washington Department of Ecology, "Wetland Rating System for Western WA: 2014 Update " (DOE. 2014). The 2014 rating system required in the Federal Way Municipal Code, Section 19.410(1). The wetland delineation was completed on May 21, 2015, by Jeffery S. Jones, Professional Wetland Scientist. The wetland flags are orange, preprinted "Wetland Boundary", and tied on���°r`� vegetation. See the attached wetland sketch for wetland flags and sample point locationsz.-A?�'� . censed landsurveyor *ill locate the wetland `boundary and stream ordinary high-water mark 41 (OH WM) and prepare.a critical..area snap. .A site plan has not been prepared as of the date of this report. 4.0 General Site Description The site is a 0.53-acre parcel residential property. There is an existing double -wide mobile home in poor condition and detached garage, see attached photos. A drainage pattern crossing the property in a north -south direction, between 20th Ave S. and the existing structure. Die blft There is a culvert under the driveway. 5.0 Vegetation 5.1 Vegetation Methodology Hydrophytic vegetation has adaptations that allow these species to survive in saturated or inundated environments. These environments are classified according to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, 1979). The probability of species being found in wetland environments has been determined by the U.S. Fish and Wildlife Service in the National List of Vascular Species that Occur in Wetlands: 1996 National Summary (Lichvar, 2016). An indicator status was applied to each species according to its probability of occurring in wetlands (see Table 1.0). Vegetation data was recorded at three sample locations distributed across the property with at least one sample location in each plant community. At each sample location, the dominant species were assessed by indicator status to determine if the plant community was predominantly hydrophytic. Rules for determining dominant species were established in the Washington State Wetlands Identification and Delineation Manual (DOE, 1997). Table 1.0 Plant Indicator Status Indicator Category Symbol Occurrence in Wetlands Obligate Wetland OBL > 99% Facultative Wetland FACW 67-99% Facultative FAC 34-67% Facultative Upland FACU 1-33% Upland UPL < 1 % Note: FACW, FAC, and FACU have + and — values to represent species near the wetter end of the spectrum (+) and the drier end of the spectrum (-) (Lichvar, 2016). 5.2 Vegetation Results At sample location 1 (SL-1), the plant community is dominated by Western red cedar (Thuja plicata, FAC), weeping willow (Salix babylonica, NL), red alder (Alnus rubra, FAC) and English ivy (Hedera helix, FACU). The plant community is hydrophytic because more than 50% of the dominant species are FAC, FACW, or OBL. At SL-2, the plant community is dominated by Western red cedar (Thuja plicata, FAC), Laurel (Laurus nobilis, NL), unidentified grasses (NI), and creeping buttercup (Ranunculus repens, FAC). The plant community is hydrophytic because more than 50% of the dominant species are ' FAC, FACW, or OBL. 2 6.0 Hydrology 6.1 Hydrology Methodology The Washington State Wetlands Identification and Delineation Manual requires inundation, flooding, or saturation to the surface for at least 5% of the growing season to satisfy the hydrology requirements for jurisdictional wetlands (DOE, 1997). Areas that are saturated between 5% and 12.5% of the growing season may or may not be wetlands. The growing season can either be defined by the number of frost -free days (temperatures above 281F), or the period during which the soil temperature at a depth of 19.7 inches is above biological zero (41°F). The presence of wetland hydrology was determined at each sample location by evaluating a variety of direct and indirect indicators, consistent with the Washington State Wetlands Identification and Delineation Manual and the U.S. Army Corps of Engineers Wetland Delineation Manual (DOE, 1997)( COE, 1987). In addition to direct visual observation of inundation or saturation, secondary hydrologic indicators were used to infer wetland hydrology. Secondary indicators include oxidized channels (rhizospheres) associated with living roots and rhizomes, water marks on vegetation or fixed objects, drift lines, water -borne sediment deposits, water stained leaves, surface scoured areas, wetland drainage patterns, morphological plant adaptations, and hydric soil characteristics. Another secondary indicator is the FAC-Neutral test, which is used to determine if the plant community is hydrophytic when all species with FAC indicator status are disregarded. 6.2 Hydrology Results SL-1 has wetland hydrology. A water table was present at 6 inches below the surface. Saturation was present at the soil surface. SL-2 does not have wetland hydrology. The soil profile is dry to the surface. The water table is not present within the upper 18 inches from the surface. There are no indicators of wetland hydrology. 7.0 Soils 7.1 Soils Methodology Hydric soils are soils that are "saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (COE, 1987)." They are either organic soils (peats and mucks) or are mineral soils that are saturated long enough to produce soil properties associated with a reducing environment. These soils have hydric characteristics such as a reduced matrix (a matrix that changes color when exposed to air), redox depletions (gleying), or redox concentrations (mottles). Soils were visually assessed for hydric characteristics and organic content in an 18-inch soil pit at each sample location. In Washington State, soil color is the main indicator used to determine if a soil is considered hydric. Soil color immediately below the "A" horizon or at a depth of 10 inches below ground surface was determined using Munsell Soil Color Charts (MacBeth, 2000). Soils that had a one-chroma matrix or a two-chroma matrix with mottles were determined to be hydric. 7.2 Soil Series The on -site soils were mapped by the USDA Soil Conservation Service (SCS) as Alderwood gravelly sandy loams, see attached Soils Map. 7.3 Soils Results The soil at SL-1 is a hydric. It most like a Norma silt loam which is a common inclusion in drainages mapped as Alderwood. From 0 to 18 inches, the soil is a very dark grey (IOYR 3/1) silt loam. The soil has a thick dark surface. The soil is hydric because it has a one-chroma matrix immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). The soil at SL-2 is a non-hydric Alderwood gravelly sandy loam. From 0 to 6 inches, the soil is a very dark brown (1 OYR 2/2) Alderwood gravelly sandy loam. From 6 to 16+ inches, the soil is a dark yellowish brown (IOYR 4/4) Alderwood gravelly sandy loam. The soil is non-hydric because it has a four-chroma matrix immediately below the "A" horizon or at ten inches, whichever is shallower (DOE, 1997). 8.0 Wetland Determination, Rating, and Buffer The bottom of the drainage, adjacent to the stream, meets all three criteria for wetlands. Soils have a thick dark surface. A water table is present at 6 inches. The plant community is dominated by invasive English ivy with an overstory of Western red cedar and red alder. The remainder of the subject property is upland. The soils are a medium brown dry gravelly sandy loam. Its hydrogeomorphic classification is a Riverine wetland, because the stream floods above the stream channel at least one every year. Sediment on the English ivy leaves is present from prior flooding. The main source of wetland hydrology is runoff from impervious surface that are upstream. The wetland is Palustrine forested (PFO) class of vegetation (Cowardin, 1979). The wetland has a total score of and a habitat score of. It rates as a Category III wetland, FWMC. 19.145.420(1)(c). The wetland buffer requirement for a Category III wetland with a habitat score of . , MC. 19.145.420(2). 9.0 Stream, Rating, and Buffer The stream is 2-4 feet wide, a bare substrate of rocks and sediment. The stream is seasonal d non -fish bearing. Therefore, the stream is a Type Ns. The stream buffer requirement is�feet FWMC 19.145.270.1(c). 4 10.0 Functional Assessment The wetland functions were assessed using the 2014 DOE Wetland Rating System for Western Washington. The rating system scores the wetland based on characteristics that contribute to habitat, hydrologic and water quality functions (see attached DOE Wetland Rating Form). The wetland provides moderate water quality functions. The on -site wetland is small, but the drainage is important in the overall landscape. It has vegetation that traps sediment and pollutant from surface runoff. The wetland has an opportunity to improve water quality because untreated water from residential areas and streets. The wetland provides moderate hydrologic functions. The drainage is import to the landscape. However, the site is small and flow -through is rapid. The wetland has little opportunity to reduce the impact of flooding by moderating downstream flows. The wetland provides low habitat functions for wildlife. There is extensive development of the area that impacts wildlife access. Non-native invasive plants dominate the wetland and wetland buffer, including English ivy and Himalayan blackberry. 11.0 Impacts The applicant proposes to remove the existing double -wide mobile home and possibly remove the detached garage. A new single-family residence will be constructed outside of the critical area buffers. The existing gravel driveway will be used for access. The remaining wetland buffer could be restored by removing debris, invasive plants, and restoring the buffer to a native plant community. 12.0 Authority This wetland determination is in accordance with Section 404 of the Clean Water Act, the objective of which is to "maintain and restore the chemical, physical, and biological integrity of the waters of the United States (DOE, 1997)." Wetlands are "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (CFR, 1982.) 13.0 Limitations Wetland determinations and delineations are not final until approved by regulatory agencies and/or local jurisdictions. J. S. Jones and Associates, Inc. does not guarantee acceptance or approval by regulatory agencies, or that any intended use will be achieved. 14.0 References Cowardin, Lewis M. 1979.

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. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 0go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the 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 your wetland can be classified as a Flats wetland, use the form for Depressional wetlands, Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; .At least 30% of the open water area is deeper than 6.6 ft (2 m). (NLQ go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit 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. NO - go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit 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 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number -A— NO - go to 6 YES The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. �- go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit 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. awlrN 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 the wetland unit being scored. 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 HGM 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. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine e Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

The site contains a mapped stream classified as a Major Stream per the city's Critical Area Inventory, with a standard 100-foot stream buffer. In June 2015, the city's critical area ordinance was updated. As such, the applicant must provide a waterway delineation and water typing pursuant to Washington Administrative Code (WAC 222-16-030). The above study classifies the stream as a Type Ns (seasonal non -fish habitat), and identified wetlands on the subject property.

This land use review does not require a pre -application conference; however it is highly advisable to determine the requirements and help you with the process (drainage, traffic impact fees, school impact fee determination, right of way improvements and other general zoning requirements for attached multi -family units). The critical area peer review funds for a review of the submitted critical area report were received last week from Mr./Ms. Melinchuk- our consultant has been contacted to start their review. Pre -application conferences will take about 3-4 weeks to schedule a meeting with you- a follow up letter will come about a week later from with a submittal checklist etc.- I may or may not be the project manager assigned to your proposal. I would check on the school district fees (contact Permit.Center@cityoffederalway.com)- due at the time of building permit issuance- for multi -family units as these fees have been increased recently in the last few years by Federal Way Public Schools. The MF designation applies to any development above one unit. You will have to contact Sarady Long and explain you situation to see if a Concurrency permit is required for the this proposal. You may also consider an attached or detached accessory dwelling unit versus a duplex or triplex. Either the ADU or primary residence must have the owner residing in it at least 6 months of the year. Kind regards, Leila W-Oakes ***Due to permit volumes, first review targets are 3-5 weeks from submission/ resubmission. *** L.
