We respectfully request a modification of certain landscape requirements that apply to this project, which is located within the CE-Commercial Enterprise Zone. Requirements for this zone include: (a) Type III landscaping five feet in width shall be provided along all property lines abutting public rights -of -way and access easements, except industrial uses shall provide Type II landscaping ten feet in width along such property lines. (b) Type I landscaping 15 feet in width shall be provided along the perimeter of the property abutting a residential zoning district, except industrial uses shall provide Type I landscaping 25 feet in width along such property lines. (c) Type III landscaping five feet in width shall be provided along the perimeter of the property abutting a nonresidential zoning district, except industrial uses shall provide Type 11 landscaping ten feet in width along such property lines. Along the north property line, this project primarily abuts the S 356t" St Regional Detention Facility, which is owned by the City and is a part of this project. On the northwest corner, however, the project abuts Used Tire Warehouse, a commercial business. The owner of this property has requested that the City not install Type III landscaping as required along the northerly property line, as it would block the view of his business. Since the purpose of the Type III landscaping is to provide a visual buffer that this property owner does not want, and since we are not installing structures, parking, or storage facilities that might require screening, we request that this requirement be modified along the north property line. We propose instead a five-foot wide strip of low, evergreen shrubs along the Used Tire Warehouse property line, and a mixture of evergreen and deciduous trees, shrubs, and groundcovers throughout the project. A portion of the property frontage on S 356th Street, for a distance of approximately 600 feet extending east from the intersection of S 356" Street and Pacific Highway S, will be landscaped but will not strictly meet the definition of Type III landscaping. This area is located on the outside of a six-foot high, approximately 3:1 embankment that will contain the constructed wetland. The types of plants that can be placed on this embankment are limited due to the possibility of tree roots damaging the bank. As a result, we cannot plant evergreen trees along this area. We are proposing a few small, flowering deciduous trees Janet Shull Landscape Modification Request February 13, 2013 Page 2 in pockets where the grade flattens, along with flowering evergreen and deciduous shrubs of varying heights, groundcover, and wildflowers. To the east, the embankment recedes. In this area we are proposing a wooded area with numerous evergreen and deciduous trees, shrubs, and groundcover. This area is expected to meet and exceed the Type III landscape standard. Since the intent of Type III landscaping is' to 'soften the appearance of parking areas and buildings which we are not proposing, and we propose to meet or exceed the Type III standard as much as possible elsewhere on the site, we request that a portion of the frontage be landscaped without evergreen trees and reduced numbers of deciduous trees. Please contact me if you have any questions.

Subject: Draft Wetland and Stream Delineation Technical Memorandum for the South 356th Street/SR 99 Intersection Improvements Project Purpose of the memorandum This memorandum documents the wetlands and streams found in a portion of the South 3561h Street/SR 99 Intersection Improvements Project area. The study area consists of the area east of Pacific Highway South (also known as State Route 99) and south of the existing South 356" Street (Attachment 1). All of the study area is within the Hylebos Creek drainage basin. A two step process was used to determine the presence of wetlands and streams in the study area. In step one, HDR staff reviewed existing environmental documents. The second step was a field evaluation. The initial field reconnaissance was followed by delineation of wetlands and streams within the study area. These steps and the results are discussed in detail below. Document Review HDR Staff reviewed the following existing environmental documents to determine the presumed presence of wetlands in the South 356th Street/SR 99 Intersection Improvements Project study area: ■ National Wetland Inventory Wetland Mapper (htto.,//wetiandsfws.er.uNs.gov/wtinds/launch.html) • King County Wetland Inventory (ht#p:8www.metrokc.govlgis/mapportal/iMAP main-htm) • Soil Survey of King County Area, Washington (Snyder et al., 1973) ■ City of Federal Way zoning and critical areas maps (htto://www.cityoffederalway.com/Pa.ge.aspx?view-3411) • Friends of the Hylebos Wetlands website (http://www.hylebos.orgrndex.htm) Wetlands No wetlands were mapped on the proposed South 356th Street alignment. A single large wetland (Wetland 32-21-4-119) is mapped to the south of the alignment and extending over to SR 99 at 359th (see attachment 1). Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S. 356�h Street / SR 99 Intersection Improvement Project Page 1 Streams One stream (the headwaters of the North Fork Hylebos Creek) is mapped in the study area. North Fork Hylebos Creek crosses the study area flowing east along South 3561h Street and then south out of the study area. Zoning The study area is zoned BP, for business park development (Attachment 1). Zoning for surrounding areas includes business development and residential districts. Land Use The portion of the study area near the intersection of South 356th Street and SR 99 is currently used for commercial purposes and the eastern half is vacant. Areas to the south are entirely vacant, and are currently vegetated with a mixture of forested and shrub wetland and forested upland communities. The surrounding land uses include a mixture of vacant land and commercial and residential developments (Attachment 2). A commercial tire recycling operation and a large stormwater facility (operated by the City if Federal Way) are located to the north. The parcel on Pacific Highway South (west of the Federal Way Parcel) immediately south of the proposed South 356"' Street alignment is occupied by a motel. Field Reconnaissance Vegetation, soil, and hydrologic conditions were observed in several locations along the proposed South 356"' Street alignment. No wetlands were identified in the proposed South 356"' Street alignment; however two wetlands were identified to the south and east. Vegetation in proposed south 3561h Street alignment is dominated by a mixture of bentgrasses (Agrostis sp.) and disturbance tolerant forbs (hairy cat's ear [Hypocharis radicata], plantain [Plantago sp_],) and small red alder (Alnus rubra) and black cottonwood (Populus balsamifera) saplings (Photographs 1, 2, and 3). The areas to the north and south of the alignment are forested. The forest canopy dominated by red alder and black cottonwood with a few scattered western red cedar (Thuja plicata). The understory is predominantly Himalayan blackberry (Rubus armeniacus) with salmonberry (Rubus spectabilis), snowberry (Symphoricarpos albus), redtwig dogwood (Corpus sericea), and Indian plum (Oemleda cerasiformis) locally dominant. Reed canarygrass (Phalaris arundinacea), sword fern (Polystichum munitum) and bracken fern (Pteridium aquilinum) are the dominant herbaceous species. Some areas of shallow surface ponding (approximately 1 inch) were observed near the proposed alignment, but this likely result from recent rainfall on the compacted surface. No saturated soils were observed in this area. Soils in the forested area were loose and well drained, with no indications of saturation or ponding. No redoxymorphic features were observed in the soils along the proposed South 3561h Street alignment (See data plot Beck-U1). This slope to the south of the proposed alignment show ample evidence of filling. Construction debris (large rocks, wood material, and a street lamp base) was present on the surface, and the stem of a western Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S. 35eh Street / SR 99 Intersection Improvement Project Page 2 red cedar tree was partially buried by dirt and debris, subsequently killing the tree. An old erosion control fence is located at the top of the bank. Both the fill and the fence likely date to the time of the tank removal and cleanup. Wetlands HDR Staff visited the study area on November 29th and 30th, and December 9th, 2005 to confirm the location of wetland boundaries and stream ordinary high water marks. Two wetlands were identified. Detailed descriptions of the wetlands are provided below, and a summary of the characteristics of the wetlands identified in the field reconnaissance is provided in Table 1. A description of the delineation methods is provided in Appendix A. Note that the boundaries delineated by HDR biologists have not been reviewed by regulatory agencies, and should be considered preliminary. Table 1.

Wetland 32-21-4-119 Description Wetland 32-21-4-119 occupies a broad flat area on either side of North Fork Hylebos Creek Attachment 1 and Figure 1). Habitats present in Wetland 32-21-4-119 include forested, scrub/shrub and emergent communities. Vegetafion The northern edge of Wetland 32-21-4-119 consists for forested wetland. The canopy is dominated by red alder although occasional western red cedar trees are also present (Photographs 4 and 5). A few scattered western hemlock (Tsuga heterophylla) trees are present on hummocks, and black cottonwood is dominant in the south and west. Salmonberry is the dominant shrub, although scattered hardhack (Spiraea douglasil) shrubs are also present. Herbaceous vegetation is largely absent in the northern end of Wetland 32-21-4-119, although reed canarygrass, stinging nettle (Urtica dioica), and creeping buttercup (Ranunculus repens) were observed further away from the wetland boundary (Photograph 7). Vegetation in the southern portions of Wetland 32-21-4-119 is predominantly red alder and black cottonwood, although occasional western red cedar. The understory includes Sitka, pacific, and Scouler's willows (Salix Sitchensis, S. lasiandra var. lucida, and S. scouleriana), vine maple (Acer circinatum), salmonberry and hardhack (Spiraea douglasil). The herbaceous vegetation includes reed canarygrass, stinging nettle, lily -of - the -valley (Maianthenum dilatatum), creeping buttercup, and skunk cabbage (Lysichiton Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S. 356rh Street / SR 99 Intersection Improvement Project Page 3 americanum). Several emergent areas are present in Wetland 32-21-4-119. Emergent areas in the north are dominated by creeping buttercup and reed canarygrass, and the emergent area along SR 99 north of 356` Street is predominantly reed canarygrass. The dominant species in Wetland 32-21-4-119 are facultative or wetter, and their presence satisfies the hydrophytic vegetation criterion. The adjacent uplands to the north are dominated by disturbed upland forest, which slope upward and west onto the motel parcel, and upward and north (Photographs 4 and 5). Vegetation on these slopes is predominantly red alder and black cottonwood, although big leaf maple (Acer macrophyllum) and western hemlock are also present. The understory is dominated by dense thickets of Himalayan blackberry, but vine maple and salmonberry are also present in substantial quantities. The herbaceous stratum is predominantly stinging nettle, and mosses are common on the surface of the ground to the north. Adjacent upland along South 3591h Street and Pacific Highway South include disturbed upland forest and mowed road edges. The canopy of this forest is predominantly red alder and black cottonwood, although Douglas fir and big leaf maple are also present. The understory includes dense thickets of Himalayan blackberry, and more dispersed Indian plum, red elderberry (Sambucus racemosa), hardhack, and Scouler's willow. Occasional ornamental shrubs (apples [Malus domestica] and holly [llix aquifolium]) were also present. The herbaceous strata includes reed canarygrass, largeleaf avens (Geum macrophyllum), cleavers bedstraw (Gallium aparine) and creeping buttercup. Sword fern, bracken fern, and western St John's wort (Hypericum formosa) are locally abundant. Hydrolpgy Elevated groundwater appears be the primary water source for the northern portion of Wetland 32-21-4-119. Overflows from North Fork Hylebos Creek are channeled directly under the proposed South 2561h Street alignment to Wetland 32-21-4-119 in a concrete culvert (Photographs 8-10), and likely also play an important role in the hydrology of the system. Runoff from adjacent uplands may also contribute water to the wetland. Areas of shallow inundation and soils saturated to the surface were observed in Wetland 32- 21-4-119 (Photographs 6 and 13). The presence of saturated soils in the upper 12 inches of the soil profile is indicative of wetland hydrology. Adjacent upland areas are well drained. Soils were excavated to a depth of at least 17 inches, and no saturation was observed (Photographs 14 and 15). Soils Soils in the northern portion of Wetland 32-21-4-119 were composed of black (10YR 2/1) silt loam extending to a depth of more than 16 inches (Photograph 13). In the southern portion of the wetland, a narrower layer of this silt loam overlies a layer of gleyed, greenish gray (5GY 6/1) clay to olive gray (5Y 5/2) clay loam with fine prominent redoxymorphic features. The presence of this low chroma soil colors and redoxymorphic features meets the wetland soil criterion. Soils in the adjacent uplands were generally loam overlying fine sands to gravelly sandy loam. Glass, PVC pipe and other construction debris were common on the (likely) filled slopes to the north (Photographs 12 and 14). Soils to the west of Wetland 32-21-4-119 appear to be natural, and have some hydric characteristics before meeting the fill slopes Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S_ 356`" Street / SR 99 Intersection Improvement Project Page 4 to the motel site. The owners of the motel site indicate that this area was substantially wetter in the past. Conclusion All three wetland criteria (wetland vegetation, hydrology, and soils) were present in Wetland 32-21-4-119. The presence of positive indicators for these three criteria meets the wetland definition. Wetland Ratin The City of Federal Way classifies Wetland 32-21-4-119 as a Category I wetland under the Federal Way Community Code (FWCC 22) due to the size and number of wetland communities. Category I wetlands require a standard buffer width of 200 feet. Our field observations confirm the approximate location of the wetland as shown on Zoning Map No. 98. Wetland 2 Description Wetland 2 is a small (approximately 2,440 square feet) forested wetland located between Wetland 1 and Pacific Highway South (see Figure 1). It occupies a shallow depression in the upland terrace east Wetland 1. Wetland 2 is not shown on the Federal Way Wetland Inventory. Vagetation Vegetation in Wetland 2 is dominated by red alder and black cottonwood, with an understory of hardhack and salmonberry. The herbaceous stratum is dominated by creeping buttercup and largeleaf avens, though some small pockets of slough sedge (Carex obnupta) are present. The overall plant community is dominated by species ranked as facultative or wetter, which satisfies the wetland vegetation criterion. The surrounding uplands are dominated by similar species, but also include dense thickets of Himalayan blackberry, along with reed canarygrass and cleavers bedstraw (see Appendix A, data sheets 1 U and 21-1). Much of the area east of the pullout on Pacific Highway South has been paved with asphalt in the past. The asphalt has become covered with a thin layer of organic debris and herbaceous vegetation. Hydrology Wetland 2 appears to receive its water as runoff from the adjacent uplands. Saturated soils were observed in the upper 12 inches of the soil profile during the delineation, but the B and C horizons were not saturated. This may be the result of the relatively impermeable strata trapping water at the surface. The presence of saturated soils in the upper 12 inches of the soil profile meets the wetland hydrology criterion. Soils Soils in Wetland 2 consist of a very dark gray (10YR 3/1) silt loam overlying a dark grayish brown (2.5Y 4/2) gravelly silt loam with many, large dark yellowish brown (10YR 4/6) redoxymorphic features. The presence of low chroma soil colors with redoxymorphic features meets the wetland soil criterion. Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S. 3560 Street / SR 99 Intersection Improvement Project Page 5 Conclusion All three parameters (wetland vegetation, hydrology, and soils) were present in Wetland 2. This supports the conclusion that the area meets the definition of a wetland. Wetland Elating Wetland 2 is less than 2,500 square feet in size and has only one wetland habitat type. Wetlands less than 2,500 square feet are not regulated by the City of Federal Way, and do not have buffer requirements. It should be noted that the City may determine that Wetland 2 is functionally connected to Wetland 1. If this is the case, Wetland 2 would be regulated under Federal Way's community code, and would receive a rating and the applicable buffer. While activities in Wetland 2 would not be regulated by the City of Federal Way, the area does meet the three parameter wetland definition, and is still subject to regulation by state and federal agencies. The US Army Corps of Engineers regulates fill all wetlands that are not isolated, and the Washington State Department of Ecology regulates activities in all wetlands, regardless of whether they are isolated or not. Final determination of whether a wetland is isolated or adjacent rests with the US Army Corps of Engineers. Streams Three streams (North Fork Hylebos Creek and two unnamed tributaries) were identified in the study area during the field investigation. A detailed description of the streams is provided below, and a summary of stream characteristics is provided in Table 2. Table 2.

All ratings shown in this table are preliminary and have not been reviewed by the City of Federal Way or other regulatory agencies - Washington State Department of Natural Resources stream types are based on the Forest Practices Rule for (WAC 222-16- 031). All stream rating and typing is preliminary and has not been reviewed by the City of Federal Way or other regulatory agencies. Stream Description: North Fork Hylebos Creek The North Fork Hylebos Creek is a perennial stream. While the City of Federal Way maps for the area show a portion of the channel on the north side of South 3561h Street, no channel was observed in this area (Photographs 16 and 17). The former channel may have been pied into a culvert and control structure (Photograph 18) on the north side of South 356t Street. The stream crosses South 359lh Street to the east of SR 99 and flows eastwards near the toe of slope for South 356th Street. Approximately 250 feet to the east, North Fork Hylebos Creek turns to flow south where it crosses the study area. The stream continues to flow southwards, crossing under South 359th Street approximately 1,000 feet west of SR 99. Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S. 356rh Street / SR 99 Intersection Improvement Project Page 6 North Fork Hylebos Creek crosses under South 3561h Street in a concrete culvert (Photograph 19). The stream width at the Ordinary High water Mark (OHWM) varied from 6 to 10 feet. A small, riprap lined channel (separated from the main channel by more riprap) extends south approximately 50 feet to an 18 inch concrete culvert, which carries the overflow southward to Wetland 32-21-4-119 (Photographs 8 to 10). Forest vegetation (red alder, black cottonwood, Himalayan blackberry, snowberry, and salmonberry) provides approximately 100 percent cover for the overflow channel. The main stem of North Fork Hylebos Creek travels east along the south side of South 356th Street. The channel in this reach varies from 6 to 10 feet wide at the Ordinary High Water Mark (OHWM), and the banks are approximately 4 feet high and steeply sloped. Riprap has been placed along the banks to stabilize the stream. A small ridge of dirt is located immediately south of the stream, likely this material was excavated to create the current stream channel. The substrate in this reach is largely fines, although some riprap is also present in the channel. The stream is characterized by relatively fast moving water with few riffles. Forest vegetation (as described above) provides approximately 100 percent stream cover (Photographs 29 and 30). This riparian vegetation is approximately 100 feet wide to the south and 20 feet wide to the north, where the stream buffer meets South 3561h Street (Photograph 31). Approximately 250 feet east of the culvert, North Fork Hylebos Creek turns to the south. The OHWM in this reach varies from 3 to 8 feet in width, and the steep banks are approximately 4 to 5 feet high. Riprap walls line portions of the eastern bank. The substrate includes more gravel; small pools (approximately 5 feet long and 1 foot deep) alternate with shallow riffles. Small cascades (12 to 18 inched high) occur approximately every 40 feet. Riparian vegetation is similar to the previous reach, and extends approximately 20 feet east of the stream and 100 feet to the west. These stream conditions prevail southward to the limits of the study area (Photographs 32 through 34). Stream Description: Tributaries to North Fork Hylebos Creek Tributary 1 drains the southwest portion of Wetland 32-21-4-119. It is a small stream, approximately 18-24 inches wide at the OHWM (Photograph 35). Tributary 1 begins at a dense thicket of salmonberry and hardhack, and flows approximately 50 feet to the south before crossing under South 3591h Street in a culvert. The substrate is predominantly silts and sands, but the flow of water appears relatively rapid and consistent. No pools were observed. Tributary 2 flows west to east along the north side of South 359`h Street. It is approximately 50 feet long, and 18-24 inches wide at the OHWM. Tributary 2 begins near the emergent portion of Wetland 32-21-4-119 near the intersection of South 3591h Street and Pacific Highway South, and flows eastwards to join Tributary 1 approximately 10 feet north of the culvert under South 359t" Street. The substrate of Tributary 2 consists of silts and sands. The water in Tributary 2 is slow moving, and the numerous pools contain iron rich algae. Stream Ratings The North Fork of Hylebos Creek is a fish bearing stream. Fish bearing streams in the City of Federal Way are classified as major streams, and require a standard setback of 100 feet. Draft Wetland and Stream Delineation Technical Memo December 2005 City of Federal Way — S_ 356'h Street /SR 99 Intersection Improvement Project Page 7 Tributary 1 and Tributary 2 are tributaries to North Fork Hylebos Creek. All tributaries to fish bearing streams in Federal Way are classified as major streams, and require a setback of 100 feet. Summary No wetlands were identified on the proposed South 3561h Street alignment. A large wetland (Wetland 32-21-4-119) was identified on to the south of the proposed alignment, and a second smaller wetland was located to the southeast of the alignment. Wetland 32-21-4-119 is rated Category I by the City of Federal Way, and the required 200 foot buffer would likely extend into the proposed alignment. A Jurisdictional Determination should be requested from the US Army Corps of Engineers to confirm the -boundary of Wetland 32-21-4-119 and Wetland 2 in the project vicinity. North Fork Hylebos Creek flows east and south across the study area. North Fork Hylebos Creek is classified as a major stream by the City of Federal Way, and requires a 100 foot buffer. This stream buffer extends extend south and west of the stream onto the proposed alignment. Two smaller tributaries are present along South 3591h Street. Buffers and setbacks for these streams are either within existing wetlands or paved areas of South 359th Street. Construction of the proposed improvements for the South 356th Street/SR 99 Intersection Improvements Project will affect North Fork Hylebos Creek, its buffer, and the buffer of Wetland 32-21-4-119.

HDR Engineering, Inc. staff collected data for each of the three parameters (hydrophytic vegetation, hydric soils, and wetland hydrology) in areas that represent typical site conditions. Staff collected additional data in associated uplands as needed to confirm wetland boundaries. These data were recorded on standard wetland delineation data sheets (attached). VEGETATION The dominant plants and their wetland indicator status were evaluated to determine if the vegetation was hydrophytic. Hydrophytic vegetation is defined as vegetation adapted to wetland conditions. To meet the hydrophytic vegetation criterion, more than 50 percent of the dominant plants must be Facultative, Facultative Wetland, or Obligate, based on the wetland indicator category assigned to each plant species by US Fish and Wildlife Service (USFWS) (Reed, 1997). Table 1 lists the definitions of the indicator categories. Table 1. Definitions of Wetland Plant Indicator Categories used to Determine the Presence of Hydrophytic Vegetation Wetland Indicator Category Symbol Definition Obligate Wetland Plants OBL Plants that almost always (> 99% of the time) occur in wetlands, but which may rarely (< 1% of the time) occur in non - wetlands. Facultative Wetland Plants FACW Plants that often (67 to 99% of the time) occur in wetlands, but sometimes (1 to 33% of the time) occur in non -wetlands. Facultative Plants FAC Plants with a similar likelihood (34 to 66% of the time) of occurring in both wetlands and non -wetlands - Facultative Upland Plants FACU Plants that sometimes (1 to 33% of the time) occur in wetlands, but occur more often (67 to 99% of the time) in non - wetlands. Upland Plants UPL Plants that rarely (< 1 % of the time) occur in wetlands, and almost always (> 99% of the time) occur in non -wetlands - Source: Reed (1997). HDR biologists used A Field Guide to the Common Wetland Plants of Western Washington and Northwest Oregon (Cooke, 1997) and Plants of the Pacific Northwest (Pojar and MacKinnon, 1994) as field references to assist with plant identification. Scientific and common plant names follow currently accepted nomenclature. Most names are consistent with Flora of the Pacific Northwest (Hitchcock and Cronquist, 1973) and the PLANTS Database (USDA, 2004). Draft Wetland and Stream Delineation Technical Memo December2005 City of Federal Way — S. 356 h Street / SR 99 Intersection Improvement Project Page 11 HYDROLOGY Project staff examined the area for evidence of hydrology. Wetland hydrology criteria were considered to be satisfied if it appeared that the soil was seasonally inundated or saturated to the surface for a consecutive number of days greater than or equal to 12.5 percent of the growing season. The growing season begins when the soil reaches a temperature of 41 degrees Fahrenheit in the zone of root penetration. The growing season in low elevations in western Washington is typically considered to be from March 1 to October 31 (244 days) (Washington State Department of Ecology 1997). Primary indicators of hydrology include surface inundation and saturated soils. Secondary indicators of hydrology include drainage patterns, watermarks on vegetation, water -stained leaves, and oxidized root channels. SOILS Generally, an area must contain hydric soils to be a wetland. Hydric soil forms when soils are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (12 inches). Biological activities in saturated soil result in reduced oxygen concentrations and organisms turn to anaerobic processes for metabolism. Over time, anaerobic biological processes result in certain soil color patterns, which are used as indicators of hydric soil. Typically, low-chroma colors are formed in the soil matrix, and bright -colored redoximorphic features form within the matrix. Other important hydric soil indicators include organic matter accumulations in the surface horizon, reduced sulfur odors, and organic matter staining in the subsurface (NRCS, 2003). BOUNDARY IDENTIFICATION The delineated wetland boundaries were flagged with sequentially numbered, bright pink flagging. Boundaries were numbered in the order in which they were encountered in the field, and numbering does not necessarily reflect geographic location. Data plot locations were flagged with blue and white striped flagging and labeled with the wetland and plot number. Field data sheets for wetlands are provided in Appendix A. The ordinary high water marks (OHWMs) of streams were flagged with blue flags on the Parcel 1, and blue and white striped flags on the Federal Way Parcel. Flags were generally paired (e.g. 1, 1a) and consecutively numbered. All delineated wetlands and streams will be instrument -surveyed and maps will be prepared by the surveyors.
