Sincerely, Isaac Conlen Planning Division Manager for Patrick Doherty, Director enc: Exhibit A, Findings for Project Approval Approved Site Plan Approved Mitigation Plan, Prepared by Grette Associates, dated October 14, 2013 c: Scott Sproul, Assistant Building Official Ann Dower, Senior Engineering Plans Reviewer Chad Wallin, Grette Associates, 2102 North 30`h Street, Suite A, Tacoma, WA 98403 Queenie Farrell, PO Box 3072, Federal Way, WA 98063 13-105327 Dm I.D.64946 s C4TY OF ''ft-O/ Federal Way EXHIBIT A FINDINGS FOR PROJECT APPROVAL SOLTYS DRIVEWAY WETLAND BUFFER INTRUSION, REASONABLE USE File #13-105327-00-UP The following are findings for recommending conditional approval of a wetland buffer intrusion proposal that includes a new driveway- intrusion into a portion of the buffer and mitigation plan. 1. Proposal — The subject property is 65,775 square feet (1.51 acres) of vacant land. The applicant proposes to construct a new two-story single-family residence, two attached garages, and associated site work. Access to the property is off of 6`h Place SW. Directly across the street from the subject property and 6h Place SW, is a pond and Category I regulated wetland and a 200-foot buffer that extends onto the subject property. The applicant proposes to construct a 15-foot-wide driveway that would extend through the buffer and connect to 6P' Place SW. 2. Zoning and Comprehensive Plan — Zoning for the subject site is Residential Single -Family (RS-7.2). Construction of a detached dwelling unit is a permitted use in this zone subject to the provisions of Federal Way Revised Code (FWRC) 19.200.010. The Federal Way Comprehensive Plan (FWCP) designation for the subject site is Residential Single -Family. The wetland buffer intrusion is subject to `Reasonable Use of the Subject Property,' and single-family residential lots are reviewed under Process III, Project Approval, as provided in FWRC 19.150.040. 3. Public Notice — The application was deemed complete on December 13, 2013, and a Notice of Application was posted on December 20, 2013. The notice was posted at the subject property, posted at each of the city's official notification boards, published in the Federal Way Mirror, and mailed to property owners within 300 feet of the subject property. The comment period due date was January 6, 2014, and one comment was received. 4. Environmental Review —The application is exempt from review under the State Environmental Policy Act (SEPA) as it does not exceed city adopted flexible thresholds set forth in FWRC 14.15.030(a) for construction of residential structures up to twenty dwelling units. 5. Wetland Buffer Intrusion — On October 2, 2012, the applicant applied for a Single Family Building Permit (File #12-104496-00-SF) and was notified that the City's wetland inventory designated a portion of the subject property within the 200-foot Category I wetland buffer area. The proposed driveway was intruding into the wetland buffer and therefore, a wetland report is required to be submitted to the city for review. On November 9, 2012, the city received a request and funding for a wetland basic review from the applicant. The city forwarded the request to our wetland consultant, Grette Associates, for their review. A Technical Memorandum was prepared by Grette Associates, dated December 28, 2012, and it was concluded that the off -site wetland meets the FWRC definition of a Category I wetland and the 200-foot wetland buffer extends on to the property. Fisher's Pond and associated Wetland A is located 50 feet southwest of the subject property and the 200-foot buffer extends onto the subject property by approximately 17,976 square feet. The construction of the proposed driveway will intrude through the wetland buffer to connect to 6`h Place SW. Ordinarily, a request to reduce the wetland buffer would be processed through FWRC 19.175.040(5). However, the maximum reduction allowed is 50% and the driveway intrudes all the way through the buffer, exceeding the 50% threshold. Therefore, pursuant to FWRC 19.150.040, Reasonable use of the subject property, a modification of the buffer requirements to allow `reasonable use' of the property is proposed. Grette Associates was then hired by the applicant to prepare a Compensatory Mitigation Plan to address compensation for unavoidable adverse effects from the proposed driveway on the wetland buffer "Soltys Wetland Buffer Mitigation Plan." dated October 14, 2013. Reasonable Use ofthe Subject Properly — The city may approve a modification or waiver of the requirements of this division on a case -by - case basis based on the following criteria: (a) The application of the provisions of this division eliminates all reasonable use of the subject property. Staff Response: Per FWRC 19.175.040, any improvement can only intrude 50% into the buffer, which is not possible in this situation. In order to gain reasonable use of the property and have access to the proposed single-family residence, the driveway must intrude entirely through the buffer. Therefore, as proposed, this criterion is met. (b) It is solely the implementation of this division, and not other factors, which precludes all reasonable use of the subject property. Staff Response: It's the wetland buffer intrusion that precludes the reasonable use of this property and not any other factors. This criterion is met. (c) The applicant has in no way created or exacerbated the condition which forms the limitation on the use of the subject property, nor in any way contributed to such limitation. Staff Response: The applicant bought the land in its current condition not knowing there was a wetland buffer onsite. Per the mitigation plan, the existing wetland buffer on site is likely providing little wetland buffer function due to the disconnection from the wetland caused by the paved road, constructed prior to this proposal. The applicant has in no way created or exacerbated the conditions and this criterion has been met. Soltys Driveway Wetland Buffer Intrusion 13-105327-00-UP/Doc. I.D. Gas» Findings for Approval Page 2 (d) The knowledge of the applicant of limitations on the subject property when he or she acquired the subject property. Staff Response: As stated above, the applicant was unaware of the wetland buffer onsite when the property was purchased. The applicant was made aware of the wetland and associated buffer after a single-family building permit was submitted to the city for review. This criterion is met. (e) The waiver or modification will not lead to, create, nor significantly increase the risk of injury or death to any person or damage to improvements on or off the subject property. Staff Response: Impacts associated with single-family development are anticipated. No increased impacts to health, safety, or welfare of neighboring property are anticipated. Criterion met. Based on the criteria above and the mitigation plan, the proposed driveway intrusion is approved as conditioned. Mitigation Plan — The proposed 15-foot driveway will permanently remove approximately 1,741 square feet of the wetland buffer area. Impacts to the wetland buffer will be mitigated through the construction of vegetated bioswales that will be constructed parallel to the portion of the driveway that is within the wetland buffer. These actions will be accompanied by revegetating any additional area that is disturbed during the construction of the driveway within the buffer area. Based on the existing health of the vegetation within the buffer area, enhancement of the wetland would not increase the existing buffer functions. Therefore, the proposed compensation is designed to provide water quality enhancement associated with stormwater runoff from the proposed driveway and adjacent upland area. Constructing two bioswales within the wetland buffer area will provide the opportunity to filter out sediments and pollutants from stormwater originating from the driveway. The vegetated bioswales will be planted with native shrubs and seeded with a native seed mix to reduce erosion and increase the native species diversity within the buffer. During excavation and grading, Best Management Practices (BMPs) will be employed to minimize erosion of disturbed surface soils and to prevent sediment -laden runoff from leaving the project site. A compliance inspection to confirm the plan was followed and installed appropriately will be conducted. A compliance memorandum prepared by a qualified biologist will be prepared and must be submitted to the city within 60 days following completion of all compensatory mitigation actions. 6. Storm Drainage System — The applicant is proposing a biofiltration swale on both sides of the proposed driveway to provide water quality treatment and minor infiltration as soils will allow. Roof runoff from the house will require separate facilities. 7. As conditioned, the proposed site plan application and application attachments have been determined to be consistent with the Federal Way Comprehensive Plan, all applicable provisions of the FWRC, and with the public health, safety, and welfare. The streets and utilities in the area Soltys Driveway Wetland Buffer Intrusion 13-105327-00-UP/n«. IR 64877 Findings for Approval Page 3 of the subject property are adequate to serve the anticipated demand from the proposal, and the proposed access to the subject property is at the optimal location and configuration for access. The proposed development is consistent with Process Ill, Project Approval, and FWRC 19.150.040, Reasonable Use of the Subject Property. The proposed site plan and application attachments have been reviewed for compliance with the Federal Way Comprehensive Plan, pertinent zoning regulations, and all other applicable City regulations. Final construction drawings will be reviewed for compliance with specific regulations, conditions of approval, and other applicable City requirements. This decision shall not waive compliance with future City of Federal Way codes, policies, and standards relating to this development.

Based on an October 14, 2013, Wetland Buffer Mitigation Plan by Grette Associates, it shows that Fisher's Pond is located approximately 50 feet southwest of the subject property and a portion of the wetland buffer is located on the eastern portion of the subject parcel. At the time of preparation of the plan, Fisher's Pond was classified as a Class I Wetland with a 200 foot buffer. The City's Critical Areas Regulations have changed, effective June 30, 2015. However, it is very likely that Fisher's Pond will remain a Category 1 Wetland (bogs and wetlands of high conservation value), with a required buffer of 190 to 225 feet based on its habitat scores. Regardless of the buffer width, it has been determined that based on the location of 611, Place SW, a paved road to the east of the parcel, the existing wetland buffer west of 61h Place SW is likely providing little wetland buffer function due to the disconnection from the wetland caused by the paved road. The City therefore grants your request for a buffer reduction based on Federal Way Revised Code (FWRC) 19.145.440(4), which states: 19.145.440 Development within wetland buffers. (1) Generally. Except as allowed in this section, no development or improvement may be located within a wetland buffer. .................................... (4) Permanently altered buffer. The director may provide written approval for a buffer reduction when existing conditions are such that portions of the required buffer exist in a permanently altered state (e.g., roadways, paved parking lots, and permanent structures) and do not provide any buffer function. The buffer may be reduced up to the area where the altered conditions exist. This means that due to the location of 611, Place Shy/ between the subject parcel and Fisher's Pond, the wetland buffer ends on the eastern portion of the paved roadway.

For a complete description of the wetland discussed herein, please refer to this report. Soltys Wetland Buffer 1 October 2013 Mitigation Plan Grette Associates, LLC This Plan has been prepared in compliance with the requirements of the FWRC 19.175.040 and was prepared using the guidance from Wetland Mitigation in Washington State (Ecology, USACE, and EPA 2006). 1.1 Responsible Parties Project Proponent: Vitaliy Soltys 1505 S 344a' St. Federal Way, WA 98003 2 PROJECT DESCRIPTION 2.1 Existing Conditions Report Preparer: Grette Associates, LLC Chad Wallin, Biologist 2102 N 30a' Street, Ste A Tacoma, WA 98403 253-573-9300 The site is approximately 65,775 square feet (1.51 acres) in size and is currently undeveloped. The property is made up of a forested community that is dominated by red alder (Alnus rubra) and Douglas fir (Pseudotsuga menziesii). Beneath the forest canopy is a shrub layer that is dominated by salmonberry (Rubus spectabilis). No structures currently exist on the property. With the exception of the wetland buffer associated with Fisher's Pond, no other critical areas were identified on the property. 2.2 Proposed Actions The applicant proposes to construct a new two-story single family residence on the subject property (Figure 3). The location of the structure is proposed in the western portion of the property. In addition to the single-family residence, two attached garages and associated concrete parking will be constructed. Access to the residence will be from 6`h Place SW and will consist of a 15-foot wide asphalt driveway. Prior to the construction of these features, areas of the property will be cleared of vegetation and minor grading will occur. 2.3 Regulatory Summary Fisher's Pond is located approximately 50 feet southwest of the subject property and is classified as a Palustrine Aquatic Bed/Forested Wetland. Based on the Washington State Department of Ecology's (Ecology) Washington State Wetland Rating System for Western WA — Revised (Hruby 2006), and the City of Federal Way Revised Code (CFRC 19.175), Fisher Pond is a Category I wetland and shall have a standard buffer width of 200 feet. Although the subject property does not contain any critical areas, Fisher's Pond is located within 200 feet of the subject property (Grette Associates 2012). Typically, only local jurisdictions regulate wetland buffer impacts. Soltys Wetland Buffer 2 October 2013 Mitigation Plan Grette Associates, LLC Figure 2.

As described above in Section 2.3, there are no critical areas within the subject property. However, southwest of the property, across 6`h Place SW, is a Category I wetland (Fisher's Pond) that is within 200 feet of the property. A portion of the 200- foot buffer for this wetland extends onto the subject property (Figure 3). Within the subject property there is approximately 17,976 square feet of wetland buffer area. No impacts to critical areas are proposed for this project. The affected critical area buffer is summarized below in Table 1. Table 1. Proposed Critical Area Impact Summary by Type. Impact Type Impact Area (sf) Duration Wetland Buffer 1,741 sf Permanent Total 1,741 sf 3.1 Wetland Impacts No wetland impacts will occur during the proposed project. 3.2 Wetland Buffer Impacts The proposed project will construct a new 15-foot wide asphalt driveway, extending approximately 226 linear feet from rich Place SW to the proposed location of the new single-family residence (Figure 3). The total length of the driveway that is proposed within the wetland buffer area is approximately 116 feet and will permanently remove approximately 1,741 square feet of wetland buffer area. In addition, during the construction of the proposed driveway there will likely be temporary wetland buffer impacts adjacent to the driveway footprint. These impacts will be associated with the grading and clearing of the driveway area and will occur over a 1 to 3 week period. 3.3 Affected Functions and Values The wetland buffer area that is within the subject property is forested with a dense shrub layer beneath. However, the existing wetland buffer west of 6`h Place SW is likely providing little wetland buffer function due to the disconnection from the wetland caused by the paved road. The presence of 6ih Place SW provides a hydrological barrier for surface water that would otherwise flow into the wetland. Currently, the surface water that sheet flows toward the road from the wetland buffer is likely intercepted by the vegetated area adjacent to the paved edge of the road and conveyed to a stormwater catch basin. Although wetland buffer functions are likely limited west of 61h Place SW, the buffer area does provides some wildlife habitat. The dense vegetation within the property likely provides large and small mammal foraging and cover, passerine, waterfowl, and raptor foraging and nesting, and amphibian foraging and refuge. Social values include aesthetic and ecological characteristics. Soltys Wetland Buffer 5 October 2013 Mitigation Plan Grette Associates, LLC The construction of the proposed asphalt driveway will result in the removal of vegetation that currently provides refuge for wildlife and will reduce stormwater infiltration due to the impervious surface of the driveway. Impervious surfaces do not allow stormwater to infiltrate, thus the water collected on these types of surfaces tend to create a surge of stormwater runoff during rain events. The stormwater will also likely collect sediments and pollutants from the impervious area as the water is conveyed off of its surface. 4 MITIGATION APPROACH The proposed project was designed and configured to avoid and then minimize impacts to the critical areas within the project area. Unavoidable impacts to the wetland buffer will be mitigated through the construction of vegetated bioswales that will be constructed parallel to the portion of the driveway that is within the wetland buffer (Attachment A, Sheet 1 & 2). These actions will be accompanied by revegetating any additional area that is disturbed during the construction of the driveway within the buffer area. 4.1 Mitigation Sequencing As required by the City of Federal Way, this section describes the efforts made by the project proponent to apply mitigation sequencing to the proposed project. Mitigation sequencing is a set of steps designed to prevent unavoidable impacts to the environment, and then to rectify those impacts that cannot be avoided. The steps considered during the planning of this project are discussed below. 1. Avoidance The environmental impacts associated with the project are unavoidable. Based on the location of the subject property and adjacent properties, the only feasible road access to the property is off of 6`h Place SW (Figure 3) and through the wetland buffer. hi order to access the subject property a driveway must be constructed through the wetland buffer to connect 6t' Place SW. 2. Reduction Relocating the driveway to avoid environmental impacts is not feasible. Based on the City of Federal Way code, CFRC 19.135.270, the maximum driveway width for a single family residence is 20 feet. The proposed driveway has been reduced to 15 feet in width. 3. Restoration Due to the requirements needed to access the property, the restoration of the permanently affected area is not feasible. The construction process will require extending approximately 116 feet of asphalt driveway through the wetland buffer area, which will permanently remove 1,741 square feet of wetland buffer. Areas outside of the permanently lost buffer that are temporarily affected by Soltys Wetland Buffer 6 October 2013 Mitigation Plan Grette Associates, LLC construction of the driveway will be restored to pre -impact conditions as specified below in Section 5.2. 4. Compensation The project proponent proposes to compensate for the affected functions within the wetland buffer area through the construction of vegetated bioswales and by restoring any portion of the wetland buffer that is disturbed during the construction. The proposed bioswale construction and buffer restoration will occur immediately adjacent to the driveway (Appendix A). 4.2 Goals and Objectives The overall goal of the Mitigation Plan is to compensate for lost of wetland buffer functions resulting from project construction. More specific mitigation goals include: • Provide water quality enhancement; • Provide enhanced hydrological wetland buffer function; • Restore upland vegetation diversity. Specific Functional objectives of the Plan include: 1. Create two 4 ft. x 70 ft. vegetated bioswales; 2. Restore upland vegetation in all disturbed areas. 5 COMPENSATORY MITIGATION PLAN Compensatory mitigation will occur on the subject property (Appendix A). Actions proposed at the site include constructing two vegetated bioswales and revegetating any additional area that is temporarily disturbed during the construction of the driveway within the buffer area or mitigation area. The proposed compensation for the project was determined based on the existing wetland buffer functions and conversations with the City of Federal Way planning department. Based on the existing health of the vegetation within the buffer area, enhancement of the wetland buffer (i.e. vegetation enhancement) will likely not increase the existing wetland buffer functions. Therefore, the proposed compensation is designed to provide water quality enhancement associated with stormwater runoff from the proposed driveway and adjacent upland area. The impact area, approximately 1,741 square feet, consists of an approximately 15-foot by 116-foot area where an asphalt driveway will be constructed. This area is currently a forested community dominated by red alder and Douglas fir with an understory of shrubs dominated by salmonberry. 5.1 Target Functions 5.1.1 Wetland Buffer Functions The target function proposed for improvement within the buffer area is water quality. Water quality within the buffer will be enhanced by collecting and treating stormwater Soltys Wetland Buffer 7 October 2013 Mitigation Plan Grette Associates, LLC runoff associated with the proposed driveway. Currently, the groundcover within the forested buffer is mostly bare and likely does not filter out large amounts of sediments and pollutants from surface water. Constructing two bioswales within the wetland buffer area (north and south sides of the driveway) will provide the opportunity to filter out sediments and pollutants from stormwater originating from the driveway. The wetland buffer areas adjacent to the proposed driveway and bioswales will also be planted with native shrubs and seeded with a native seed mix to reduce erosion and increase the native species diversity within the buffer. 5.2 Mitigation Design The intent of the compensatory mitigation actions at the subject property is to offset the permanent loss of function of wetland buffer area within the site. Mitigation actions include constructing two vegetated bioswales and restoration of the adjacent wetland buffer area using native plantings. 5.2.1 Grading Plan Initially, the extent of the proposed grading will be clearly marked, and silt fencing will be installed along the outer grading extents. All vegetation within the areas proposed for excavation and grading will be mechanically removed. Grading and clearing limits within the wetland buffer area will be limited to 10 feet on either side of the paved driveway edge. During excavation and grading, Best Management Practices (BMPs) will be employed to minimize erosion of disturbed surface soils and to prevent sediment -laden runoff from leaving the project site. BMPs to be employed during construction may include (but are not limited to) silt fencing and/or straw bales around the perimeter of the clearing and grading areas, mulching area immediately after completion of grading, and installation of plant material as soon as practical after grading. Once the vegetation is removed, grading will be conducted using bull dozers, excavators, dump trucks and other like equipment as needed to complete the work. Prior to the final grade and paving of the driveway, the two bioswale will be excavated and constructed to typical design standards presented in Attachment A, Sheets 1 and 2. Plantings within the bioswales and adjacent areas will be installed once the final grade and paving is achieved. 5.2.2 Planting Plan Planting installation will be performed in accordance with the specifications outlined in this plan. Any alterations to the planting plan due to site conditions will require approval from the project biologist and appropriate regulatory agencies prior to installation. The project proponent is only proposing planting within the designated mitigation area and bioswales (Appendix A, Sheet 3). The intent of vegetating the bioswales and adjacent areas is to create a vegetated area that will likely provide water quality and hydrological functions within the area proposed for impacts. The herbaceous species will be planted in clumps of four and each clump will be spaced on 2-foot centers and will include Dewey's sedge (Carex deweyana), Soltys Wetland Buffer 8 October 2013 Mitigation Plan Grette Associates, LLC northwest territory sedge (Carex utriculata), and Dagger leaf rush (Juncus ensifolius). Shrub species will be planted in clusters among the emergent vegetation on 4- to 6-foot centers and will include Nootka rose (Rosa nutkana), cluster rose (Rosa pisocarpa), Scouler's willow (Salix scouleriana), and Indian plum (Oemleria cerasiformis). The remaining bare areas within the mitigation site, including the bioswales, will be seeded with an approved native seed mix. 5.2.3 Planting Schedule The proposed planting schedule for the mitigation area is presented below in Table 2. The specific quantities of each species will be calculated during final design of the mitigation action. In order to reduce mortality, a late fall planting installation (October — November) schedule is preferred. Plants should not be installed during or immediately before freezing weather. Table 2.

Any alterations to the planting plan due to site conditions will require prior approval from the project biologist and/or City Planner. All plant materials to be used on the site will be native to Western Washington and will consist of nursery grown stock from a reputable, local dealer. Only native species specified in the approved plant schedule are to be used; no hybrids will be allowed. Plant substitutions must be approved by the project biologist if specified species are not commercially available. Plant material provided will be typical of their species or variety; they will exhibit normal, densely -developed branches and vigorous, fibrous root systems. Plants will be sound, healthy, vigorous plants free from defects and all forms of infestation. 5.2.4 Preparation and Installation of Planting Materials The landscape contractor shall verify the location of all elements of the landscape plan prior to installation. The project biologist may adjust the locations of landscape elements during the installation period as necessary. 1 Emergent species shall be planted with four (4) plugs per clump. Soltys Wetland Buffer 9 October 2013 Mitigation Plan Grette Associates, LLC Circular plant pits with vertical sides will be excavated for all container stock. The pits should be at least twice the diameter of the root system, and the depth of the pit should accommodate the entire root system. The bottom of each pit will be scarified to a depth of 4 inches, and the pit should be thoroughly wetted prior to plant insertion to prevent capillary stress. The planting hole shall be amended with a mixture of topsoil and organic material if necessary to provide appropriate rooting media. Broken roots should be pruned with a sharp instrument and rootballs should be thoroughly soaked prior to installation. Set plant material upright in the planting pit to proper grade and alignment. Water plants thoroughly midway through backfilling and add Agriform tablets. Water pits again upon completion of backfilling. No filling should occur around stems. Do not use frozen or muddy mixtures for backfilling. Form a ring of soil around the edge of each planting pit to retain water, and install a 2-1/2 inch layer of mulch around the base of each container plant. 5.2.5 Compliance Inspection A compliance inspection will consist of evaluating the plantings immediately after construction to confirm the plan was followed and were installed appropriately. The compliance inspection will also evaluate the construction of the two bioswales. A walk- through survey will be conducted to verify that installation conforms to the approved plan. Following the completion of the compliance inspection, a compliance memorandum will be prepared by a qualified biologist to document the construction and verify that all design features have been correctly implemented. Any changes to the planting plan will also be discussed in the compliance memorandum. Photographs will also be taken to document the completion of the mitigation area. The memorandum will be submitted to the appropriate regulatory staff within 60 days following completion of all compensatory mitigation actions. 5.2.6 Photographic Documentation As described above, photographs will be taken during the compliance inspection in order to obtain representative photographs of the mitigation site. Photographs will be taken at each end planted area to document the planting and the construction of the bioswales. 5.3 Performance Standards Performance standards provide a clear means of evaluating the success of a mitigation action. The following performance standards have been developed to reflect the goals and functional objectives detailed in Section 4.2 of this document. The performance standards specifically related to this project and presented below in Table 3. Soltys Wetland Buffer 10 October 2013 Mitigation Plan Grette Associates, LLC Table 3.

The contingency actions will vary depending on whether physical or biological processes are responsible for non -attainment of performance standards, and the degree of shortfall. If the Project fails one or more performance standards, but the permitting agencies agree the shortfall is minor, then additional plantings, or like action, prior to undertaking more intense corrective actions may be proposed. 6.1 Contingency Actions This contingency plan identifies a planning process for selecting appropriate actions to address failure of specific performance standards. In order to maintain the flexibility needed to respond effectively and appropriately to biological and/or physical conditions, this plan does not present a specific list of actions that will be taken to remedy all specific types of failures at the site. Failure of biological components of the mitigation actions are more difficult to predict and specific responses are impossible to present in detail. However, the following general approach is anticipated: If the vegetation planted in the planted areas fails to meet the performance standards, additional planting of the same or alternate species may occur.

The City's wetland inventory designated a portion of the property within the 200-foot Category I wetland buffer area. Under Federal Way Revised Code (FWRC), any development activity within 200 feet of a Category I wetland requires the applicant to submit a wetland report prepared by a qualified professional approved by the City. WETLAND REPORT The City forwarded your request to our wetland consultant, Grette Associates, for their review. Biologist Chad Wallin visited the subject site and reviewed relevant documents. His December 28, 2012, technical memorandum stated that the wetland area associated with the subject property is a Category I wetland and the 200-foot buffer extends onto the property. REVIEW PROCESS Based on the findings of the wetland report, the following review processes are required to construct a driveway within the buffer area of the above -mentioned property. Intrusions into a regulated wetland buffer — As mentioned in the wetland report, there is a Category I 200-foot wetland buffer along the eastern property line. The construction of the proposed driveway will intrude through the wetland buffer. Ordinarily, your next step would be to request a reduction of the wetland buffer in accordance with FWRC 19.175.040(5). However, the maximum reduction allowed under that section is 56% and the driveway improvement intrudes all the way through the buffer. Therefore, pursuant to FWRC 19.150.040, Reasbnable use of the subject property, you may request a modification or waiver of the buffer requirements to allow "reasonable use" of the property based on the following criteria: a) The application of the provisions of this division eliminates all reasonable use of the subject property. b) It is solely the implementation of this division, and not other factors, which precludes all reasonable use of the subject property. c) The applicant has in no way created or exacerbated the condition that forms the limitation on the use of the subject property, nor in any way contributed to such limitation. Mr. Manchik January 3, 2013 Page 2 d) The knowledge of the applicant of limitations on the subject property when he or she acquired the subject property. e) The waiver or modification will not lead to, create, nor significantly increase the risk of injury or death to any person or damage to improvements on or off the subject property. For projects on single-family residential lots, a reasonable use modification or waiver requires Process III land use review. Process III is an administrative review conducted by city staff with a final decision issued by the Director of Community and Economic Development. — It is - the -appIicanfs resgoa ibiIityto showhow -th-0-proposed ►uet%!Fd-u-frusions meditlie cri er�ia of �- — FWRC 19.150.040. The intrusion must be the minimum necessary to provide the applicant with some reasonable use of the subject property. The city may impose any limitations, conditions, and restrictions as appropriate to reduce or eliminate any undesirable effects or adverse impacts of granting a reasonable use request.' The formal application must be prepared in accordance with the City's Development Requirements checklist (enclosed) and must be accompanied by the appropriate fees. As fees change annually, please contact Development Specialist staff at the time of submittal for the current Process III application fees for Process III review.

Wetland Inventory Field Form Task Scope: Background: According to the Federal Way Critical Areas Map, the above - referenced site contains a portion of the 200-foot Category I wetland buffer. Federal Way Revised Code (FWRC) 19.175.040 limits improvement activity within a 200-foot buffer of Category I wetlands. The applicant would like to make improvements by constructing a driveway, for a new single family house, within the buffer area. Grette is requested to perform the following tasks: l . Verify the category of the offsite wetland (associated with Fisher's Pond) as defined in FWRC Title 19, "Critical Areas," and FWRC 19.175, "Regulated Wetlands." 2_ Establish the extent of the wetland buffer and if it encroaches onto the applicant's property.

The proposal is to construct a new 7,393 square -foot, 2-story, single-family residence with a 132 square -foot covered entry, 1,260 square -foot attached garage, and 387 square -foot deck on a vacant lot. A review of the material you submitted indicates the following issues that must be addressed prior to land use approval. CRITICAL AREA The subject site appears to be located within 200 feet of a regulated Category I wetland and the proposed driveway intrudes into the required 200-foot wetland buffer. In order to clarify the extent of critical area constraints on the subject property, a wetland review must be submitted to the city. The city's wetland consultants, who are third party reviewers, can provide a flat fee service to verify the category of the offsite wetland and establish the extent of the wetland buffer on the subject property. A nonrefundable flat fee of $1,050.00 will be required for this service. You may also choose to use your own qualified professional acceptable to the city to review the site and provide a wetland report. The city may require additional third party review of the wetland report at the expense of the applicant. Based on the evaluation of the wetland report we can then determine what land use process will be required. If it turns out that the property improvements do not intrude into a wetland buffer then review will continue on your single-family building permit. However, if the improvements do intrude into the wetland buffer, a Process III land use approval will be required. The following land use review process must be completed before the building permit can be approved. Buffer Reduction: FWRC 19.175.040(5). Through Process III `Project Approval', the Director of Community and Economic Development may reduce the standard wetland buffer width by up to 50 percent if the project includes a buffer enhancement plan that utilizes appropriate native vegetation and clearly substantiates that an enhanced buffer will improve and provide additional protection of wetland functions and values, and where one of the following conditions can be demonstrated: a. Existing conditions are such that the required standard buffer exists in a permanently altered state (e.g., roadways, paved parking lots, permanent structures, etc.) that does not Mr. Manchik November 2, 2012 Page 2 provide any buffer function, then the buffer can be reduced for that portion where the intrusions are existing. b. Except for Category I wetlands, existing conditions are such that the wetland has been permanently impacted by adjacent development activities, as evidenced by such things as persistent human alterations or the dominance of nonnative invasive species. c. A project on an existing single-family lot platted prior to the incorporation of the city, where imposition of the standard buffer would preclude reasonable use of the lot. TREE AND VEGETATION RETENTION The site plan provided does not show tree retention and/or replacement plan as required by FWRC 19.120.040(2). The tree retention standards require each development to maintain a minimum tree unit density. The minimum tree density in Single Family Residential (RS) zones is 25 tree units per acre. The subject property's tree density would be 38 tree units (25 tree units x 1.51 acres = 37.75 tree units). A tree unit is a value assigned to existing trees retained 'on the property. The larger the tree, the greater value it is assigned (e.g. an existing tree measuring between 18 inches to 24 inches qualifies as 2.5 tree units). Required tree density can be composed of retained trees and replacement plantings per FWRC 19.120.130. The site plan shows total trees on site and trees to be retained, but not the tree unit density. Please depict the tree unit calculation on the site plan. Also show tree retention fencing around retained trees in close proximity to construction activity pursuant to FWRC 19.120.160. See the enclosed form on Calculating Tree Units and FWRC Chapter 19.120, "Clearing, Grading, and Tree and Vegetation Retention."

A nonrefundable flat fee of $1,050.00 generally provides the following services: ■ Two hours of wetland or stream study review ■ Equivalent of a two hour site visit by two scientists • Preparation of a brief memorandum + Coverage of various reimbursables This service is designed to review existing wetland and stream reports and field verify flagged delineations and ratings on smaller properties. This service is generally limited to properties less than one acre in size with only limited wetland or stream conditions. For properties where no study has been prepared, arrangements can be made to use this service for onsite consultation consistent with the terms listed above. More complex situations or larger properties will require a specific consultant prepared scope of work and cost estimate. When the fee is paid, the city's consultant will contact you to schedule the site visit.

Based on the existing condition of the wetland buffer (heavily forested with a dense shrub layer) and 61h Place acting as a buffer break to the wetland, I do not believe that vegetation enhancement of the existing buffer would provide any functional lift, therefore, we are proposing to construct two vegetated bioswales along the sides of the proposed driveway and revegetate any area that will be disturbed during the construction of the driveway. The bioswales will likely provide an increase in water quality function and hydrological function to the wetland buffer by treating any stormwater associated with the sites development and revegetating any disturbed area will restore the wetland buffer to pre -impact condition. Please let me know your thoughts for approval on our proposed compensation.
