Comments from Danielle Gordon, dated April 11, 2019 The Hearing Examiner enters the following findings and conclusions based on the testimony and exhibits: FINDINGS Application and Notice 1. Mercury Michael (Applicant) requests approval of a reasonable use exception (RUEX) to allow construction of a single-family residence and associated impro vements, including a driveway and septic facilities, on a vacant lot containing a wetland and an associated wetland buffer. The unaddressed property is off of Euclid Avenue NE, between NE Endicott Street and NE Lafayette Avenue.1 The RUEX would allow for development of a single-family residence, not to exceed 1,200 square feet, with a reduced wetland buffer of 25 feet and a 15-foot construction setback. As mitigation for the proposal, the Applicant would remove invasive species throughout the site and wo uld install a variety of native vegetation in a 1,800 square foot mitigation area within the remaining wetland buffer. Exhibit 1, Staff Report, pages 1 and 7 through 9; Exhibit 7; Exhibit 9; Exhibit 10; Exhibit 19. 2. The City of Bainbridge Island (City) determined that the application was complete on January 2, 2019. On January 11, 2019, the City provided notice of the application and the associated open record hearing by mailing or emailing notice to property owners within 500 feet of the subject propert y and to reviewing government departments and agencies, and by publishing notice in the Bainbridge Island Review. On January 13, 2019, notice of the application and associated hearing was also posted at the project site. 1 The property is identified by tax parcel number 41670000240003. Exhibit 1, Staff Report, page 3. A legal description of the property is included with the project plans. Exhibit 7. Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 3 of 16 The City received one public comment in response to its notice materials: Andrew Fiscus, who lives at the adjacent property to the south, expressed concern that the location of the proposed residence would create privacy concerns and that allowing development of a residence on a property with a protected wetland that drains into the Port Madison Water Company’s property, or the Puget Sound, is ecologically insensitive. Mr. Fiscus suggested that the septic drainfield be sited close to the south property line to allow an increased setback between his residence and the proposed residence. Exhibit 1, Staff Report, page 4; Exhibit 12; Exhibit 13; Exhibit 14; Exhibit 16. State Environmental Policy Act 3. The City determined that the proposal is exempt from review under the State Environmental Policy Act (SEPA), Chapter 43.21C Revised Code of Washington (RCW), and Washington Administrative Code (WAC) 197-11-800(1)(b)(i), because it would involve minor new construction. Exhibit 1, Staff Report, page 1. Comprehensive Plan, Zoning, and Surround ing Property 4. The property is designated “Residential District -2” under the City Comprehensive Plan. The purpose of the City’s Residential District designation is to provide for less intensive residential development and a variety of agricultural and forestry uses. City Comprehensive Plan, LU-22. City staff analyzed the proposal for consistency with the Comprehensive Plan and identified goals and policies applicable to the proposal, including:  Using mitigation sequencing to develop properties adjacent to or adjoining critical areas to account for the present and future need to reduce the potential for personal injury, loss of life, or property damage due to flooding, erosion, landslides, seismic events, climate change, or soil subsidence.  Employing conservation design methods and principles such as low-impact development techniques for managing stormwater and wastewater, and using green building materials and high-efficiency heating and lighting systems.  Protecting wetlands and riparian areas.2 Exhibit 1, Staff Report, pages 5 and 6. 5. The 0.37-acre property is within the “Residential 2” (R-2) zoning district. The purpose of the R-2 zoning district is to “provide residential neighborhoods in an environment with special Island character consistent wit h other land uses such as agriculture and forestry, and the preservation of natural systems and open space, at a somewhat higher density than the R-1 district.” Bainbridge Island Municipal Code (BIMC) 18.06.020.C. Single- 2 City staff specifically identified the following goals and policies of the Comprehensive Plan as relevant to the proposal: Environmental Element Policies EN-1.2, EN-4.1, and EN-5.6; Land Use Element Policy LU- 14.1. Exhibit 1, Staff Report, pages 5 and 6. Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 4 of 16 family dwellings are a permitted use in the R-2 zone. BIMC Table 18.09.020. Exhibit 1, Staff Report, page 6. 6. Within the R-2 zoning district, certain dimensional standards apply. Specifically: a required minimum lot area of 20,000 square feet per dwelling unit; minimum lot depth and width of 80 feet; and maximum lot coverage of 20 percent. BIMC Table 18.12.020- 2. Setback requirements include: front yard setbacks of 25 feet; side yard setbacks of 5 feet (minimum) and 15 feet (total); and rear setbacks of 15 feet. BIMC 18.12.020. Two parking spaces are required for each primary dwelling. BIMC 18.15.020. Exhibit 1, Staff Report, pages 6 and 7. 7. Project plans show that the proposed single-family residence would meet the parking requirements and the minimum width and depth requireme nts, as well as the minimum setback requirements. The maximum lot coverage allowed on the 16,117 square foot property would be approximately 3,223 square feet. Because a RUEX is proposed, however, lot coverage would be limited to 1,200 square feet, as required by BIMC 16.20.080.F. As noted above, at approximately 16,117 square feet, the property is smaller than the minimum lot size allowed in the R -2 zoning district. Under BIMC 18.30.050, however, nonconforming lots that were lawfully created and record ed with the county auditor’s office, as occurred here, may be used for permitted purposes notwithstanding the minimum lot area, width, or depth requirements of the municipal code. Exhibit 1, Staff Report, pages 2 and 6. 8. The property is bounded to the west by Euclid Avenue NE and surrounding properties to the north, south, and east are also zoned for residential development and generally contain single-family residences. In addition, the Port Madison Water Company owns several nearby properties. Exhibit 1, Staff Report, page 2; Exhibit 7. Critical Areas 9. The site is undeveloped, and site topography generally slopes to the north and east. AquaTerra, LLC (AquaTerra), prepared a Wetland Delineation, dated April 16, 2018, addressing on-site critical areas. The wetland delineation was based on fieldwork conducted on February 5, 2018. AquaTerra identified a Category IV depressional wetland in the northern portion of the property, consisting of forested canopy with emergent vegetation made up of red alder, English ivy, lady fern, salmonberry, sword fern, and Indian plum. A seasonal stream flows east out of the ponding area of the wetland. No signs of recent disturbance were noted. AquaTerra determined that the Category IV wetland would, in normal circumst ances, require a 40-foot buffer, with an additional 15-foot building setback. BIMC 16.20.140.I.4, Table 6. Exhibit 9. 10. The wetland and associated buffer cover approximately two-thirds of the subject property. During the pre-development and application process, the Applicant contended Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 5 of 16 that development of a single-family residence on the property would not be possible with strict application of a 40-foot wetland buffer or through buffer modification, which would allow the wetland buffer to be reduced by 25 percent under BIMC 16.20.110. Reducing the wetland buffer by 25 percent would still result in insufficient space being available to construct a single-family residence with necessary infrastructure, including an on-site septic system, stormwater system, and space for off-street parking, especially when accounting for the required 15-foot building setback from the edge of the wetland buffer. City staff assessed the site through the site assessment review process, as required by BIMC 16.20.080.A, and concurred that developing the property with a single-family residence would only be possible through the reasonable use exception process. Exhibit 1, Staff Report, page 8; Exhibit 4; Exhibit 11. 11. The City code identifies aquifer recharge protection areas (ARPAs) as critical areas that must be protected. BIMC 16.20.100.E.1 requires any proposed development or activity requiring a site assessment review located within the R-2 zone to designate an ARPA. The City determined, however, that only 3,617 square feet of the site would be required to be retained in an ARPA and that the wetland and proposed buffer (which must be maintained in perpetuity) already occupy a greater area than this. Accordingly, City staff determined that designating an ARPA on-site would be unnecessary. Exhibit 1, Staff Report, page 13. Reasonable Use Exception 12. The City code provides for a reasonable use exception (RUEX) where the City’s critical areas ordinance (Chapter 16.20 BIMC) would deny all reasonable use of the property; where there are no reasonable alternatives with less impact to the critical area or its required buffer; where the proposal minimizes the impact through mitigation sequencing; where the proposed impact is the minimum necessary; where the inability to derive reasonable use of the property is not the result of actions by the Applicant; where the proposed total lot coverage does not exceed 1,200 square feet for residential development; where the proposal does not pose an unreasonable threat to the public healt h, safety, or welfare on or off the property; and where any alterations are mitigated. BIMC 16.20.080. 13. The Applicant proposes construction of a 1,200 square foot, single-family residence with a 500 square foot driveway and on-site septic system. To minimize adverse impacts to the wetland and buffer, the residence would be constructed in the southwestern corner of the parcel. Low Impact Development (LID) techniques would be employed to minimize ground disturbance activity and excavation, especially within the wetland buffer. Specifically, pin piles or piers would provide foundation support for the residence (as opposed to slab-on-grade construction), resulting in minimal excavation and/or ground disturbance within the wetland buffer. This would result in much of the residence being Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 6 of 16 cantilevered above the ground by 10 to 12 feet over the wetland buffer.3 No stairway or direct access to the proposed wetland mitigation area, wetland buffer, or wetland would be provided from the residence. Because the property is not located within the City’s sewer service area, an on-site septic system would be installed south of the residence, along with a septic drainfield, which would be installed in the southeast corner of the property. The 16-foot “alley” where the septic system would be installed, between the residence and the southern property line, would remain undeveloped to allow future access to the septic drainfield. This site configuration would also allow for a staging area along the southern property line during construction of the residence, and provide additional privacy for the residence sited on the property to the south. As proposed, the site layout would result in a reduction of the required wetland buffer from 40 to 25 feet. As noted, however, much of the residence would actually be cantilevered above the impacted buffer, minimizing buffer impacts. Exhibit 1, Staff Report, pages 9 and 10; Exhibit 7; Exhibit 15; Exhibit 19. 14. The Applicant would submit a Stormwater Site Plan for review and appro val prior to development. Conceptually, the Applicant intends to use full-downspout infiltration, combined with permeable pavement, in areas that support stormwater infiltration. Surface stormwater from the driveway and parking surfaces would receive pre -treatment prior to being discharged. All Hardscaping would be constructed of permeable materials or contain wide permeable jointing, where feasible, to allow infiltration. Finally, diffuse flow methods, including level spreaders, would be used to discharge bypass surface stormwater from the adjoining property to the south into the wetland, to provide for increased hydrological recharge. Exhibit 7. 15. Peter Corelis, the City’s Development Engineer, reviewed the proposal and determined that it would be co nsistent with applicable stormwater regulations and that the proposal would protect the critical area functions and values consistent with the best available science as it pertains to the incorporation of LID techniques for the purpose of handling of stormwater, retaining vegetation, and mimicking natural hydrology to the maximum extent feasible. Furthermore, he determined that the site plan conforms to the City’s Design and Construction Standards and Specifications. Mr. Corelis recommended that use of the minimal excavation foundation systems for portions of the structure within the wetland buffer and treatment of stormwater (as proposed) be included as conditions of approval for the RUEX. Exhibit 18. 3 Access to the residence would occur from the street level. The topography of the site is such that a flat shelf exists on the southern portion of the property where the driveway, entrance to the residence, garage, on -site septic system, and septic drainfield would be constructed. The topography then slopes north, at between 32 and 14 percent grade, toward the wetland. The proposed residence would be cantilevered over a portion of this slope. Exhibit 15. Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 7 of 16 16. Todd Cunningham, the City’s Building Official, also reviewed the proposal. He noted that the project must comply with the City’s construction codes, as adopted in Chapter 15.04 BMC, and that soils review would be required to ensure compliance with provisions of Chapter 4 of the International Residential Co de. Exhibit 17. 17. AquaTerra prepared a Wetland Mitigation Plan, dated October 9, 2018, addressing impacts that would result from reducing the 40-foot wetland buffer to 25 feet and addressing the compensatory mitigation that would be necessary to ensure t he integrity, function, and value of the Category IV wetland on-site and to ensure that no net loss of wetland function would result from construction of a single-family residence. The Wetland Mitigation Plan notes that much of the property, including the existing wetland buffer, consists of non-native plant species, including English ivy and dead nettle. Accordingly, to mitigate for permanent impacts to the wetland buffer from development of a 1,200 square foot residence partially within the buffer area, the Applicant would:  Remove low-lying invasive vegetation throughout the site.  Add mulch to areas where invasives are removed to help prevent re-establishment of invasive species and promote the growth of native species.  Install appropriate sedimentatio n and control measures, during construction, such as silt fencing.  Restore 1,800 square feet of the remaining, degraded wetland buffer with native vegetation.  Minimize light pollution by directing lights away from the wetland.  Minimize noise impacts by placing noise-generating equipment away from the wetland.  Keep all toxic materials out of the wetland and its buffer.  Prevent materials and debris from entering the wetland and its buffer.  Keep noise and artificial light to a minimum.  Monitor the re-established area for no less than 7 years to ensure long-term survival of installed vegetation. Exhibit 10. 18. The Applicant submitted a project narrative addressing the criteria for a RUEX under BIMC 16.20.080. The project narrative suggests that the proposal would meet the criteria for a RUEX because:  The wetland and buffer encumber the majority of the property. Because of the small size of the lot, other techniques such as buffer averaging would not be sufficient to create a functional building envelope. Obt aining a RUEX is the only way to create a buildable lot.  The proposal would minimize impacts on the wetland and buffer through appropriate mitigation sequencing, including installation of low-impact fencing between the residence and wetland buffer; selecting native plants for the mitigation area that would provide light and noise screening; using elevated Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 8 of 16 walkways around the single-family residence within the wetland buffer area; directing lights away from the wetland; utilizing a low-impact foundation design; establishing covenants to avoid the use of pesticides on the property; dispersing stormwater runoff from the adjacent parcel to the south into the wetland; and utilizing full-downspout infiltration combined with permeable pavement to provide on-site infiltration of stormwater.  The impact to the critical area is the minimum necessary to allow reasonable use of the property. An alternative site design was considered that would have entailed siting the residence approximately 5 feet from the southern prop erty line and installing the on-site septic system to the north, within the wetland buffer. This, though, would have required upwards of 700 cubic yards of fill to be placed within the wetland buffer and mitigation area (to provide a level area for the septic system) and would have significantly reduced the available size of the mitigation area. Installation of retaining walls may also have been necessary under the design alternative. In addition, no readily available construction staging area would have been possible under the alternative site design. Based on these considerations, the Applicant determined that the site layout, as proposed, would allow reasonable use of the property with fewest impacts to the wetland buffer.  The wetland and buffer were existing conditions and not created by the Applicant or the previous property owner.  One single-family residence would be built on the lot, and the residence would have a total building footprint of no more than 1,200 square feet. The proposed residence would be modest in scope and have the minimum necessary impacts on the wetland buffer.  AquaTerra provided a mitigation plan that, to the maximum extent feasible, mitigates the impacts on-site. Replanting native vegetation and removing invasive vegetatio n would enhance the existing habitat. Implementation of the mitigation plan, along with best management practices during construction, would result in no net loss of critical area function and values.  The proposal would not pose an unreasonable threat t o public health, safety, or welfare on or off the site and would be consistent with other building and zoning regulations.  All other adjacent parcels have been developed. No adverse cumulative impacts are anticipated from development of the site. Exhibit 7. 19. City staff also analyzed the proposal for compliance with the RUEX criteria from BIMC 16.20.080 and generally concurred with the Applicant’s assessment. Staff specifically noted:  The Applicant would not be able to develop the lot without the requested RUEX. Lot coverage of 1,200 square feet is considered reasonable on lots encumbered by critical areas or associated buffers. Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 9 of 16  Given the small lot size, site topography, and the property’s location, there do not appear to be any other reasonable alternatives to the proposed use that would achieve the same purpose for the Applicant with less impact to the critical area buffer.  The proposal minimizes impacts on the wetland buffer in accordance with mitigation sequencing requirements under BIMC 16.20.030. Specifically: the residence would be located outside of the wetland itself and in the outermost portion of the wetland buffer; the proposal avoids the use of fill and/or retaining walls by placing the septic system on the flat, southern portion of the site; the project avoids grading within the wetland buffer by incorporating natural topography into the site design; the proposal includes a garage as part of the 1,200 square foot SFR, which would help minimize pollutant runoff; a low impact approach would be used to minimize ground disturbance and excavations; the residence would be cantilevered over the wetland buffer, minimizing impacts; fencing and signing would be provided along the wetland buffer edge, to prevent encroachment; light would be direct away from the wetland and buffer and the Applicant would establish covenants to restrict the use of pesticides on-site; invasive species would be removed from the site; enhancement of an 1,800 square foot mitigation area would be provided; and site monitoring would occur for at least 7 years.  The proposed impact to the critical area is the minimum necessary to allow reasonable use of the property. The City considers a 1,200 square foot building envelope as reasonable when a lot is encumbered by critical areas, provided enough mitigation is proposed to adequately compensate for impacts. Site alternatives were considered and deemed infeasible.  The inability of the Applicant to derive reasonable use of the property is not the result of actions by the Applicant or the Applicant’s predecessor.  Proposed total lot coverage would not exceed 1,200 square feet.  The proposal would not pose an unreasonable threat to the public health, safety, or welfare on or off the property. Exhibit 1, Staff Report, pages 10 through 16. Testimony 20. City Planner Annie Hillier testified generally about the property and the process of reviewing the proposal. She noted that the wetland and buffer cover the majority of the property and that the request to allow the construction of a single-family residence on the lot is consistent with the Comprehensive Plan and zoning. Ms. Hillier explained that the proposed single-family residence would be sited as far south as possible, away from the wetland on-site, while still allowing for an appropriate buffer with the residence to the south and an adequate area for an on-site septic system and septic drainfield. She also explained that a 1,200 square foot residence is equivalent to others in the area and is the maximum the BIMC allows through a RUEX. Ms. Hillier noted that the slopes on-site Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 10 of 16 do not meet the definition for geologically hazardous or steep slopes. She also noted that a final mitigation plan must be submitted that specifically addresses the wetland functions and values and how the proposed mitigation would impact these functions and values. Testimony of Ms. Hillier. 21. Applicant Representative Richard Langendoen testified that the Applicant looked at several possible site configurations and determined, ultimately, that the curr ent proposal would have the fewest impacts on the wetland and its buffer. He explained that the site layout would allow perpetual access to the septic drainfield, through the 16 -foot setback between the residence and southern property line, and that the same area would provide a construction staging area and privacy for the property to the south. Mr. Langendoen stressed that low-impact development techniques would be emphasized, including cantilevering much of the single-family residence above the wetland buffer, and that best management practices would be used during construction. He also noted that hydrologic recharge would occur on-site in that diffusers would be installed to capture and divert rainwater into the wetland buffer. Testimony of Mr. Langendoen. 22. Area resident Steve Christensen testified that he owns property to the north and does not object to the proposal but wanted to ensure that stormwater from the proposal would not impact his own property and that discharged stormwater would be appropriately treated prior to discharge. Testimony of Mr. Christensen. 23. Danielle Gordon, who lives south of the property, testified that she is concerned the development will impact the privacy of her own property, based on the proposed location of the residence. She noted that the project would seem to have significant impacts on the wetland and believes developing the property would negatively impact quality of life in the neighborhood. Testimony of Ms. Gordon. 24. Mr. Langendoen testified in response to Mr. Christensen’s concerns and stressed that stormwater from the proposal would have no additional impacts on adjoining properties because all stormwater would be infiltrated on-site and post-development conditions would mimic pre-development conditions. He further noted that discharged stormwater would likely be of higher quality than currently exists. In response to Ms. Gordon’s concerns, Mr. Langendoen noted that the Applicant takes quality of life issues seriously and would take measures to ensure t hat impacts to the southern property are limited but impacts from construction would be temporary. He stressed, however, that protection of the wetland and buffer is considered a priority under the municipal code and that has dictated where the proposed residence would be located. Mr. Langendoen also explained that the inhabited portion of the home would be focused toward the north and that any windows on the south side of the residence, facing south, would actually be located in the garage. He noted that existing vegetation along the south property line could be retained Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 11 of 16 but access to the septic drainfield to the east must be retained in perpetuity. Testimony of Mr. Langendoen. 25. Applicant Mercury Michael testified that he has no intention of impairing the privacy of adjacent property owners. He intends to build a fence between the property lines but would be happy to explore installing a vegetative buffer , such as with bamboo, instead. Mr. Michael stressed that the house is oriented toward the north (i.e., the garage is sited on the south), which would further ensure privacy between the two residences. Testimony of Mr. Michael. Staff Recommendation 26. Ms. Hillier testified that City staff recommends approval of the application, with conditions. Mr. Langendoen testified that the Applicant would adhere to the conditions of approval. Exhibit 1, Staff Report, pages 13 through 15; Testimony of Ms. Hillier; Testimony of Mr. Langendoen. CONCLUSIONS Jurisdiction The Hearing Examiner has authority to hear and approve, approve with conditions, deny, or remand a request for a reasonable use exception. BIMC 2.14.030; BIMC 2.16.100; BIMC 16.20.080.E. Criteria for Review Criteria for review and approval of reasonable use exceptions are as follows: 1. The application of this chapter would deny all reasonable use of the property; 2. There is no reasonable alternative to the proposal with less impact to the critical area or its required buffer; 3. The proposal minimizes the impact on critical areas in accordance with mitigation sequencing (BIMC 16.20.030); 4. The proposed impact to the critical area is the minimum necessary to allow reasonable use of the property; 5. The inability of the applicant to derive reasonable use of the property is not the result of actions by the app licant, or of the applicant’s predecessor, that occurred after February 20, 1992; 6. The proposed total lot coverage does not exceed 1,200 square feet for residential development; 7. The proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the property; 8. Any alterations permitted to the critical area are mitigated in accordance with mitigation requirements applicable to the critical area altered; Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 12 of 16 9. The proposal protects the critical area functions and values consistent wit h the best available science and results in no net loss of critical area functions and values; 10. The proposal addresses cumulative impacts of the action; and 11. The proposal is consistent with other applicable regulations and standards. BIMC 16.20.080.F. The criteria for review adopted by the City of Bainbridge Island City Council are designed to implement the requirement of Chapter 36.70B RCW to enact the Growth Management Act. In particular, RCW 36.70B.040 mandates that local jurisdictions review proposed de velopment to ensure consistency with City development regulations, considering the type of land use, the level of development, infrastructure, and the characteristics of development. RCW 36.70B.040. Conclusions Based on Findings With conditions, the proposal would comply with the reasonable use exception criteria of BIMC 16.20.080.F. The City provided reasonable notice and opportunity to comment on the application. The City determined that the proposal was exempt from SEPA review. A wetland and wetland buffer cover the majority of the Applicant’s property to the extent that strict application of the City’s critical areas ordinances would deny all reasonable use of the property. Neither the City nor public comments suggested any alternative uses for the property. The Applicant is proposing lot coverage of 1,200 square feet. The Applicant submitted a wetland delineation and a mitigation plan setting out mitigation sequencing that would minimize the impact on critical areas. The mitigation plan also det ermined that the proposal would be the minimum necessary to allow reasonable use of the property. Alternative site plans were considered but the Applicant, the Applicant’s consultants, and City staff determined that the present proposal would have the few est impacts on the wetland and its buffer. The lot was created prior to the adoption of the City’s critical area ordinances and is not the result of any action of the Applicant . The Applicant proposes construction of a 1,200 square foot, single -family residence with a 500 square foot driveway and on-site septic system. To minimize adverse impacts to the wetland and buffer, the residence would be constructed in the southwestern corner of the parcel. Low Impact Development (LID) techniques would be employed to minimize ground disturbance activity and excavation, especially within the wetland buffer. Specifically, pin piles or piers would provide foundation support for the residence (as opposed to slab-on-grade construction), resulting in minimal excavat ion and/or ground disturbance within the wetland buffer. This would result in much of the residence being cantilevered above the ground by 10 to 12 feet over the wetland buffer. No stairway or direct access to the proposed wetland mitigation area, wetland buffer, or wetland would be provided from the residence. Because the property is not located within the City’s sewer service area, an on-site septic system would be installed south of the residence, along with a septic drainfield, which would be installed in the southeast corner of the property. The 16-foot “alley” where the septic system would be installed, between the residence and the Findings, Conclusions, and Decision City of Bainbridge Island Hearing Examiner Michael Reasonable Use Exception, No. PLN51139 RUE Page 13 of 16 southern property line, would remain undeveloped to allow future access to the septic drainfield. This site configuration would also allow for a staging area along the southern property line during construction of the residence, and provide additional privacy for the residence sited on the property to the south. As proposed, the site layout would result in a reduction of the required wetland buffer from 40 to 25 feet. As noted, however, much of the residence would actually be cantilevered above the impacted buffer, minimizing buffer impacts. The Applicant’s mitigation plan contains monitoring and contingency plans, along with enhancement of the remaining wetland buffer. The City determined that the wetland delineation and mitigation plan are based on the best available science and would result in no net loss of critical area functions and values. The mitigation plan addressed the cumulative impacts of the proposed development and determined that there would be no negative cumulative impacts if the request is approved. Conditions are necessary, including those to ensure that work is completed in substantial compliance with submitted plans; construction limits are temporarily fenced; a split -rail fence is installed along the edge of the wetland buffer; appropriate signs are installed on the split -rail fence; a final mitigation plan is submitted for approval; all mitig ation plantings are installed; that a maintenance assurance device is provided prior to the issuance of a certificate of occupancy; that the Applicant record a notice of title regarding the presence of the wetland; that no refuse is placed in the wetland buffer; that stormwater on-site is appropriately managed; and that the project complies with relevant construction, building, and fire codes. Findings 1 – 26.

Hearing Examiner Review The hearing examiner shall review the reasonable use exception (RUE) application and conduct a public hearing pursuant to the provisions of BIMC 2.16.100. The hearing examiner shall approve, approve with conditions, or deny the request based on the proposal’s compliance with the RUE review criteria discussed below. Staff Recommendation Approval of the RUE, with conditions. 2 Part I: SUMMARY OF PROPOSAL The proposal is for a single-family residence (SFR) and associated driveway and septic facilities. The applicant requests a reasonable use exception (RUE) to develop the property, as the parcel is significantly covered by a category IV wetland and its associated buffer. To mitigate for impacts to the wetland buffer, the applicant proposes enhancement in the remaining buffer on-site. Four red alder trees, 13 to 16 inches at diameter breast height, will be removed, all of which are located outside of the wetland buffer. As conditioned, the project meets the eleven decision criteria for RUE review and approval in BIMC 16.20.080.F. Figure 1 – Site Plan 3 Part II: GENERAL INFORMATION AND SITE CHARACTERISTICS Assessor’s Record Information: Tax lot number 41670000240003 Owner of record Larry R. Pritchard Lot size 0.37 acres (16,117.2 sq. ft.) Terrain: The topography generally slopes to the north and east, with a total vertical relief of about 14 feet.

Public Services: Police City of Bainbridge Island Police Department Fire Bainbridge Island Fire District Schools Bainbridge Island School District Water Port Madison Water Co. Sewer n/a – septic proposed Surrounding Uses: Surrounding uses are primarily single-family residential, except the Port Madison Water Co. owns several properties nearby. Existing Zoning: The site is zoned R-2 (2 units per acre). Surrounding Zoning: The surrounding zoning is R-2 (2 units per acre) and R-1 (1 unit per acre). Existing Comprehensive Plan Designation: The Comprehensive Plan designates the site as a Residential District area. Surrounding Comprehensive Plan Designation: The Comprehensive Plan designates the surrounding area as a Residential District area. 4 Figure 2 – Vicinity Map, Aerial Image, and Zoning: Part III: APPLICATION BACKGROUND Date: Action: May 8, 2018 Preapplication conference held May 15, 2018 Preapplication summary sent to applicant (Exhibit 4), including comments from Development Engineering August 16, 2018 Original application for RUE submitted, then resubmitted on 12/19/19 with revision to project contacts (Exhibit 2) September 7, 2018 Application deemed incomplete (Exhibit 5) December 19, 2018 Applicant submitted responses to Notice of Incomplete Application (Exhibit 6) January 2, 2019 Application deemed complete, and information request sent (Exhibit 12) 5 January 11, 2019 Notice of Application with hearing date published (Exhibit 13) January 22, 2019 Applicant submitted response to information request (Exhibit 15) Part IV: PUBLIC COMMENTS (1 total) (Exhibit 16) Note: an additional comment was received after the end of the comment period on February 1, 2019; the additional comment is available in the project file. Questions/concerns raised: One commenter expressed concern about the location of the proposed SFR relative to his home, and suggested that the septic system be placed on the south side of the proposed SFR to allow for more space between structures. The commenter also stated that the proposal does not seem like the best ecological choice. Staff Response: The proposed SFR is located 16 feet from the shared lot line to the south, and the septic system is proposed between the SFR and the lot line, as suggested by the commenter. The mitigation plan concludes that the proposal will result in no net loss of wetland function, as required under by the City’s critical areas ordinance (BIMC 16.20). The granting of an RUE balances private property rights with necessary and reasonable regulation to protect the island’s designated critical areas. Part V: AGENCY COMMENT Agency: Action: Fire District Approved, no conditions City Development Engineering Approved, with conditions (Condition 12, Exhibit 17) City Building Official Approved, with conditions (Condition 13, Exhibit 18) Part VI: COMPREHENSIVE PLAN ANALYSIS The project aligns with the following Comprehensive Plan goals and policies: 1. Environmental Element Policy EN 1.2: Taking into account the present and future need to reduce the potential for personal injury, loss of life, or property damage due to flooding, erosion, landslides, seismic events, climate change or soil subsidence, properties adjoining or adjacent to critical areas must be developed in observance of the following principles in descending order: [see mitigation sequencing, below]. Staff response: The proposal utilizes mitigation sequencing, as described below. Steps taken to avoid, minimize, and compensate for impacts are described in review criteria #3 for RUE approval. Policy EN 4.1: Employ conservation design methods and principles such as low impact development techniques for managing storm and waste water, green building materials, high- efficiency heating and lighting systems. Staff response: The proposal includes a low-impact foundation design, which will reduce soil disturbance and storm-water impacts on the site. Policy EN 5.6: Protect wetlands and riparian areas. 6 Staff response: The applicant is proposing to enhance a wetland buffer. The SFR will be cantilevered above the wetland buffer and will not encroach on the wetland edge. A fence will be installed to prevent intrusion into the wetland and buffer. 2. Land Use Element Policy LU 14.1: The Residential District area is designated for less intensive residential development and a variety of agricultural and forestry uses. Staff response: The proposal is for a single-family residence with limited lot coverage. Part VII: LAND USE CODE ANALYSIS The following Bainbridge Island Municipal Code (BIMC) regulations apply to the proposal: 1. BIMC Title 18 Zoning A. 18.06.020 Purpose The purpose of the R-2 zone is to provide residential neighborhoods in an environment with special Island character consistent with other land uses such as agriculture and forestry, and the preservation of natural systems and open space, at a somewhat higher density than the R-1 district. Staff response: The proposal is for the construction of one home and the preservation of the wetland buffer outside of the area impacted by the development and as conditioned by the project. B. 18.09.020 Permitted Uses Single-family dwellings, and accessory uses and buildings to single family residences, are permitted uses in the R-2 zone. Staff response: The request is for the construction of a single-family residence, a permitted use in this zone. C. 18.12.010 Dimensional Standards Maximum Density and Minimum Lot Dimensions The minimum lot area per dwelling unit is 20,000 square feet, with a minimum lot depth and width of 80 feet. Staff response: The lot area is 16,117.2 sq. ft. The lot width and depth are approximately 110 ft. The lot is nonconforming to minimum lot area for the R-2 zoning designation. Pursuant to BIMC 18.30.050, any nonconforming single lot, tract or parcel of land that was lawfully created and recorded with the county auditor’s office may be used for the purposes permitted by this title notwithstanding the minimum lot area, lot width and lot depth required. Maximum Lot Coverage The maximum allowed lot coverage is 20% in R-2 zoning. Staff response: The maximum lot coverage allowed on the lot is 3,223.44 sq. ft. However, the maximum allowed lot coverage for RUEs is 1,200 sq. ft. 7 Setbacks In R-2 zoning, the front yard setback is 25 feet. Side setbacks are 5 ft. min, 15 ft. total. The rear setback is 15 feet. Staff response: The applicant is proposing a 25 ft. front setback, and a 16 ft. setback from the south, side lot line. The north side setback and rear setback exceed the standard setbacks. D. BIMC 18.15.020 Parking and Loading Residential dwelling units are required to provide two spaces for each primary dwelling. Staff response: The applicant is proposing a garage and driveway that will accommodate two parking spaces for the dwelling. 2. BIMC Title 16 Environment The wetland delineation report submitted with the application (Exhibit 9) identifies a category IV wetland on the north side of the subject property. The impact of land use is considered moderate, therefore the wetland requires a 40 ft. buffer by BIMC. The 40 ft. buffer consists mostly of herbaceous vegetation and groundcover. The wetland area contains forested canopy. English ivy and nettle, invasive species, are also identified in the report as present on the site. Figure 3 – Wetland and buffer 8 A. BIMC 16.20.080 Reasonable Use Exceptions Applicability and Intent An applicant may request an RUE pursuant to BIMC 16.20.080.A when a site assessment review pursuant to BIMC 15.20 or a pre-application conference demonstrates that: 1. The subject property is encumbered to such an extent by critical areas and/or critical area buffers that application of this chapter would deny all reasonable use of the subject property; 2. Reasonable use of the subject property cannot be achieved through Buffer Modification (BIMC 16.20.110 and 140) or a Habitat Management Plan (BIMC 16.20.110); and 3. Alternatives to development through an RUE are not available or acceptable. Staff response: The wetland and buffer cover approximately 2/3s of the subject property. Buffer modification allows the buffer to be reduced up to 25 percent of its required width. The applicant attempted to reduce the buffer by 25 percent but found that this would not provide a reasonable building area that also provides the required 15 ft. setback from the buffer (Exhibit 11). A Habitat Management Plan is a report that evaluates measures necessary to maintain, enhance and improve terrestrial and/or aquatic habitat on a proposed development site, and is not applicable to the development proposal or site. The only way for the applicant to develop the site with the proposed SFR is through a reasonable use exception. Reasonable Use Review Criteria The hearing examiner shall approve, approve with conditions, or deny the request based on the proposal’s compliance with all of the RUE review criteria described below. 1. The application of this chapter would deny all reasonable use of the property; Staff response: The applicant evaluated buffer modification and found that the resulting building area would not be large enough to accommodate the proposed development, while also providing the required 15 ft. setback from the reduced buffer edge. Without an RUE, application of the critical areas ordinance would not provide a building envelop large enough to accommodate a 1,200 sq. ft. SFR. 2. There is no reasonable alternative to the proposal with less impact to the critical area or its required buffer; Staff response: Single-family residential development is permitted in the R-2 zoning district. Other permitted uses in the same zoning district, such as a passive recreation park, may have less impact to the critical area buffer. However, given the small lot size, the steep-sloping topography into the wetland, and property’s location, which offers no unique viewpoints or specific recreational opportunities, such a use would not be a reasonable alternative to a single-family residence. There do not appear to be any other reasonable alternatives to the proposed use that would achieve the same purpose for the applicant with less impact to the critical area buffer. A reasonable alternative to the proposal might also be an SFR with less impact to the critical area or buffer, which is evaluated below under review criteria #4. 3. The proposal minimizes the impact on critical areas in accordance with mitigation sequencing (BIMC 16.20.030); 9 Staff response: Avoiding impacts • The SFR is located outside of the wetland and in the outermost portion of the buffer. • The proposal avoids the use of fill and/or retaining walls by placing the septic system on the flat, southern portion of the site (described in Exhibit 15). • The project avoids grading within the wetland buffer by incorporating natural topography into the site design. Minimizing impacts • The proposal includes a garage located within the SFR, which will minimize pollutant runoff. • The proposal includes incorporation of a Low Impact Development (LID) approach to minimize ground disturbance and excavations. • The SFR will be cantilevered over the wetland buffer with no stairway or other direct access to the wetland mitigation area, buffer, or wetland, which minimizes the potential for intrusion. • Temporary construction entrances and access roads will be comprised of inert materials. Recycled concrete will be prohibited. • The proposal includes fencing and signage along the wetland buffer edge, to prevent encroachment. • The proposal includes directing lights away from the wetland and establishing covenants to restrict the use of pesticides. Additional minimization steps are documented on pages 3-5 under “Proposed Site Development” in the Revised Project Narrative (Exhibit 7). The project is required to implement these steps as proposed, unless otherwise stated in the written findings, conclusions, and conditions. Rectifying impacts There are no opportunities to repair, rehabilitate, or restore the affected environment as the project represents a permanent impact to the buffer. Reducing or eliminating impacts The project cannot reduce or eliminate impacts over time by preservation and maintenance, as the project represents a permanent impact to the buffer. Compensating • The proposal includes the removal of invasive species. However, it is not clear from the proposal if invasives will be removed throughout the buffer or only in the replanting area. Staff recommends that invasives be removed throughout the entire buffer, in order to prevent re-establishment. (Condition 6) • Enhancement with native species is proposed in an 1,800 sq. ft. area of buffer, between the proposed SFR and the wetland. Monitoring the impact The proposal includes monitoring reports on an annual basis for a minimum of seven years. 4. The proposed impact to the critical area is the minimum necessary to allow reasonable use of the property; 10 Staff response: The project proposes to impact approximately 20% of the onsite wetland buffer (in the area to the west and south of the wetland), but will be cantilevered above the ground surface within this area. Staff asked the applicant to consider reversing the orientation of the septic tanks and SFR, to move the SFR even farther away from the buffer edge. As described in Exhibit 15, the applicant concluded that this would impact more of the wetland buffer, as approximately 700 cubic yards of fill and possible retaining walls would be necessary to support the septic tanks and SFR, due to the sloping topography of the site. The original proposal, which includes an LID foundation system and the septic system located on the flattest portion of the site, appears to present the least impact to the wetland buffer. A smaller SFR may result in less impact to the critical area. However, the underlying zoning supports the proposed size of the SFR, which is limited to 1,200 square feet. The City has considered an SFR of 1,200 square feet reasonable for a lot that is encumbered by critical areas, provided enough mitigation is proposed to adequately compensate for impacts. An SFR located closer to the right-of-way – for example, with a front setback reduced to 5 ft. – may also have less impact to the wetland buffer, as an even smaller portion of the SFR would be cantilevered over the wetland buffer edge. Such a proposal would require a zoning variance in addition to an RUE. However, staff did not recommend that the applicant apply for a zoning variance, based on the Hearing Examiner’s decision for another RUE (Olsen RUE, PLN51183 RUE), where the applicant testified that although a variance from the front yard setback might be possible, the cost was excessive, and the front yard play area would be reduced. In this instance, the City had recommended that the applicant seek a zoning variance as one way to significantly reduce the overall impact area, per the Department of Ecolo gy’s guidance on impact avoidance and minimization. The Hearing Examiner’s decision upheld the applicant’s proposal, which included other means of reducing impacts such as shifting the house one foot away from the wetland edge and removing a boardwalk in order to reduce the impact area. For this application, the Euclid House RUE, the applicant is proposing to reduce impacts by limiting the amount of fill and ground disturbance within the wetland buffer, and locating the majority of the SFR and the driveway completely outside of the buffer. 5. The inability of the applicant to derive reasonable use of the property is not the result of actions by the applicant, or of the applicant’s predecessor, that occurred after February 20, 1992; Staff response: The inability of the applicant to derive reasonable use of the property is not the result of actions by the applicant, or of the applicant’s predecessor, that occurred after February 20, 1992. The wetland and buffer were likely present before the current owner purchased the site in 1985. 6. The proposed total lot coverage does not exceed 1,200 square feet for residential development; Staff response: Under BIMC 18.12.050, Rules of Measurement, lot coverage means that portion of the total lot area covered by buildings, excluding up to 24 inches of eaves on each side of the building, any building or portion of building located below predevelopment and finished grade. Any portion of a slatted or solid deck located more 11 than five feet above grade shall be counted towards lot coverage. The proposed total lot coverage is 1,200 square feet. 7. The proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the property; Staff response: As conditioned, the proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the property (Conditions 1-13). 8. Any alterations permitted to the critical area are mitigated in accordance with mitigation requirements applicable to the critical area altered; Staff response: Wetland mitigation plan requirements are provided in BIMC 16.20.180.G. Note that a replanting ratio of 1.5:1 is not required, as stated in the mitigation plan. Rather, the mitigation plan is required to contain goals and objectives that are related to the functions and values of the original critical area, in accordance with BIMC 16.20.180.G.3.b. As described in the mitigation report, “much of the existing buffer consists of non-native plant species, English ivy (Herdera helix) and dead nettle (Lamium galeobdolon).” However, a discussion of the functions and values of the original critical area is not provided. To compensate for the impact to the wetland buffer, the applicant is proposing to remove invasive vegetation on the site, and to install native vegetation within an 1,800 sq. ft. area. While this may be adequate to compensate for the loss of wetland buffer function, it is not clear from the mitigation plan what those functions are. It is also not clear in what area the invasive species will be removed – the entire buffer and wetland, or only in the replanting area. Staff also observed a significant amount of English laurel on the site, an invasive species that is not identified in the mitigation plan. To meet all of the environmental goals and objectives under BIMC 16.20.180.G, the following conditions should be required: • A final mitigation plan shall be submitted and approved prior to the issuance of any permits for development, vegetation removal, land clearing, or grading. The final mitigation plan shall address the criteria under BIMC 16.20.180.G.3.b, Environmental Goals and Objectives, including: identification of functions and values; a complete description of the relationship between and among structures and functions sought; review of available literature and/or known like projects to date in restoring or creating the type of critical area proposed; likelihood of success of the proposed compensation project at duplicating the original critical area; and likelihood of the ability of the created or restored critical area to provide the functions and values of the original critical area. (Condition 5) • The final mitigation plan shall clarify the area in which invasives species will be removed. Consideration shall be given to removing invasive species throughout the project site to the maximum extent practicable, to improve the likelihood of success of the mitigation plan. If this is deemed infeasible, justification must be provided and the likelihood of success must be discussed. Any bare areas after invasive species removal shall be replanted with native vegetation, in addition to the native species proposed to be planted with the 1,800 sq. ft. mitigation 12 area. Consideration shall also be given to removing the English laurel on the site, and any other invasive species that may be present. (Condition 6) Figure 4 – Mitigation proposal 13 9. The proposal protects the critical area functions and values consistent with the best available science and results in no net loss of critical area functions and values; Staff response: The mitigation plan does not identify the functions and values of the original critical area. However, the protection measures proposed and conditioned are consistent with best available science. The mitigation plan also concludes that the proposal will result in no net loss of critical area functions and values, but supporting analysis is not provided. If Condition 5 is upheld by the Hearing Examiner, it will be clear which functions and values are protected by the proposal and how no net loss of those functions and values will be achieved. 10. The proposal addresses cumulative impacts of the action; Staff response: Cumulative impacts are the combined effects on the environment caused by past, current, and future activities. The proposal addresses, and is conditioned to address, cumulative impacts by siting and designing the development to have a minimal impact on the critical area and mitigating for any permanent loss of buffer function. Future impacts are addressed by ensuring that mitigation areas will be maintained in perpetuity and monitored for success, and by taking measures to prevent future encroachment into the critical area by installing fencing along the buffer (Condition 3). 11. The proposal is consistent with other applicable regulations and standards. Staff response: The proposal is consistent with other applicable regulations and standards of the BIMC. An analysis of these regulations and standards is provided throughout the staff report. B. BIMC 16.20.100 Aquifer Recharge Protection Area (ARPA) Aquifer recharge areas are areas that have a critical recharging effect on groundwater used for potable water supplies and/or that demonstrate a high level of susceptibility or vulnerability to groundwater contamination from land use activities. In accordance with WAC 365-190-100, the entirety of Bainbridge Island is classified as an aquifer recharge area to preserve the volume of recharge available to the aquifer system and to protect groundwater from contamination. Staff response: Pursuant to BIMC 16.20.100.E.2.b, the ARPA shall include all existing native vegetation on a site, up to a maximum of 65 percent of the total site area. A lower percentage is allowed if necessary to achieve a development area of at least 12,500 square feet on a parcel. The lot is 16,117.2 square feet in size. With an allowed development area of at least 12,500 square feet, only 3,617.2 square feet would be required to be retained in the ARPA. The wetland and buffer occupy more than this area and must be protected and maintained in perpetuity (Condition 10), therefore designating a second and smaller ARPA is unnecessary. C. BIMC 16.20.140 Wetlands Wetland Buffers Buffer widths are based on wetland category, scores for habitat functions on the rating form, and the intensity of the proposed land use. A 15-foot structure or hard surface setback is also required from the edge of any wetland buffer. Any other buffer modification 14 resulting in a reduced buffer area, other than noncompensatory enhancement or buffer modification, requires a Reasonable Use Exception pursuant to BIMC 16.20.080. Staff response: The wetland is a category IV wetland with a low level of function for habitat and a moderate impact of land use. The required buffer is 40 ft. The proposal results in a reduced buffer area and is appropriately requesting an RUE. Fencing and Signs Wetland buffers shall be temporarily fenced or otherwise suitably marked between the area where the construction activity occurs and the buffer. Fences shall be made of a durable protective barrier and shall be highly visible. Silt fences and plastic construction fences may be used to prevent encroachment on wetlands or their buffers by construction. Temporary fencing shall be removed after the site work has been completed and the site is fully stabilized per city approval. Staff response: The project is conditioned to provide temporary fencing prior to commencing construction and to maintain the fencing until the work is complete and site is fully stabilized (Condition 2). The director may require that permanent signs and/or fencing be placed on the common boundary between a wetland buffer and the adjacent land. Such signs will identify the wetland buffer. The director may approve an alternate method of wetland and buffer identification, if it provides adequate protection to the wetland and buffer. Staff response: Permanent fencing and signs are proposed by the applicant. Fencing shall be installed along the buffer edge, and shall be a maximum of 5 feet from the proposed residence. Fencing shall be indicated on building permit plans. (Conditions 3 and 4) Wetland Mitigation Requirements All development, uses and activities proposed to impact wetlands shall be mitigated according to this section and the mitigation sequencing steps outlined in BIMC 16.20.030. The applicant shall demonstrate to the satisfaction of the director that each step of mitigation sequencing has been adequately addressed prior to approval of impacts to wetlands. Staff response: As described above, the mitigation plan is required to contain goals and objectives that are related to the functions and values of the original critical area. The project is conditioned to meet this requirement (Condition 5). The project also adequately utilizes mitigation sequencing and is conditioned to further minimize impacts to the buffer. A wetland critical areas report and wetland mitigation plan is required to address impacts to the wetland and associated buffer. Compensatory mitigation may occur at the site of the allowed impacts or at an off-site location. Staff response: A wetland delineation report (Exhibit 9) and wetland mitigation plan (Exhibit 10) have been provided. The mitigation plan proposes on-site mitigation in the form of buffer enhancement. It appears that on-site mitigation is feasible, although a final mitigation plan shall be submitted prior to site development (Condition 5). The City shall require monitoring reports on an annual basis for a minimum of five years and up to 10 years, or until the director determines the mitigation project has met the performance standards specified in the wetland mitigation plan. The wetland mitigation 15 plan shall provide specific performance standards for monitoring the mitigation project. Performance standards shall be project-specific and use best available science to aid the director in evaluating whether or not the project has achieved success. Staff response: The monitoring plan proposes a seven-year monitoring period. Reports will be submitted to the City by December 31st of each monitored year. It is not clear that the performance standards are project specific, which include monitoring the survival rate of all planted vegetation and invasive species. The final mitigation plan shall include performance standards based on the goals and objectives identified in the revised plan. (Condition 8) Consideration should be given to performance standards that are specific to controlling the particular species of invasive plants on this site, survival rates of specific species to be installed, and percent cover by native species, for example. Previously approved mitigation plans have proposed a 90% survival rate for native plants and no greater than 10 percent cover by invasive species. Consideration should be given to the rates proposed, which are 75 percent and 20 percent, respectively. D. BIMC 16.20.160 Performance and Maintenance Surety The director shall decide when a performance surety is required of an applicant, and the acceptable form of such surety. The amount and the conditions of the surety shall be consistent with the purposes of this chapter; provided, that the minimum amount of the surety, when required, shall be 125% of the estimated cost of performance. A performance surety shall not be required when the actual cost of performance, as documented in a form acceptable to the director, is less than $1,000. Staff response: All plantings that are a part of the mitigation plan shall be installed prior to final building permit inspection, or an assurance device shall be provided in accordance BIMC 16.20.160 (Condition 7). E. BIMC 16.20.070.G Notice on Title The owner of any property with field-verified presence of critical area or buffer on which a development proposal is submitted shall file for record with the Kitsap County auditor a notice approved by the director in a form substantially as set forth in Subsection 2 of BIMC 16.20.070.G. Such notice shall provide notice in the public record of the presence of a critical area and buffer, the application of this chapter to the property, and that limitations on actions in or affecting such areas may exist. The applicant shall submit proof that the notice has been filed for record before the city shall approve any development proposal for such site. The notice shall run with the land and failure to provide such notice to any purchaser prior to transferring any interest in the property shall be in violation of this chapter. Staff response: The applicant shall submit a recorded notice to title prior to the issuance of the building permits, documenting the presence of the critical area onsite (Condition 10). Part VIII – CONCLUSIONS 1. Site Characteristics The property contains a category IV wetland and a 40 ft. wetland buffer that together cover a significant portion of the lot. 16 2.

A summary of the land use review process, applicable Bainbridge Island Municipal Code (BIMC) regulations, comments from reviewers, fees, submittal requirements, and next steps is provided below. General Information Pre-Application Conference Date: Nov. 14, 2017 Project Name and Number: Euclid SFR PRE - PLN51139 Project Description: Construct SFR on lot encumbered by wetland and wetland buffer Project Address: Lot 24 at Port Madison Tax Parcel Number(s): 41670000240003 Tax Parcel Size: 0.37 acres Zoning/Comp Plan Designation: R-2 Planning Contact: Annie Hillier Development Engineer: Peter Corelis Land Use Review Process Land Use Applications Required Reasonable Use Exception: BIMC 16.20.080 – A reasonable use exception (RUE) is intended to ensure reasonable use of a property when reasonable use of that property cannot be achieved through any other means. Given the extent of the wetland and wetland buffer, and the inability to achieve reasonable use of the property through other means, an RUE appears to be the only way to develop the property as proposed. Criteria for review and approval under BIMC 16.20.080.F must be addressed in the application materials, which includes a maximum total lot coverage of 1,200 square feet, and a mitigation plan developed in accordance with BIMC 16.20.180.G. A complete and detailed written statement of the reason(s) for requesting the RUE and how the proposal will meet the decision criteria (11) for review and approval under BIMC 16.20.080.F is an application requirement. One of the decision criteria (#2) requires that the applicant demonstrate that there is no reasonable alternative to the proposal with less impact to the critical area or its required buffer. It does not appear that buffer modification (BIMC 16.20.140.I.8), either through 280 Madison Avenue North Bainbridge Island, Washington 98110-1812 www.bainbridgewa.gov 206.842.7633 buffer width averaging or buffer width reduction, is feasible on the site given the small lot size and the extent of the encroachment. The applicant shall provide an analysis of alternatives considered, including buffer modification, as a part of the written statement. The RUE application requires a critical areas report prepared in accordance with BIMC 16.20.180.F, which includes a site plan that shows surveyed wetland boundaries, and a mitigation plan prepared in accordance with BIMC 16.20.180.G. I recommend providing these code references and a copy of the new CAO to the wetlands professional working on this proposal, as a new CAO was recently adopted. See the attached Administrative Manual for additional submittal requirements. Fees Planning Fees: $3,816 Approval Body Quasi-judicial decision by Hearing Examiner (BIMC Table 2.16.010) City staff will send a tentative hearing date to the applicant prior to the Notice of Application. Review and Recommendation BIMC 2.16.100: Director (review and recommendation) Planning Commission (optional) Public Hearing (report presented to hearing examiner) Other required reviews and supplemental information: Critical Area Report, including Mitigation Plan Kitsap Public Health District review Bainbridge Island Fire Department review Planning Division review Development Engineer review Bainbridge Island Municipal Code Requirements – Planning Checklist BIMC 2.16 – Land Use Review Procedures Review procedures for a Reasonable Use Exception are outlined in BIMC 2.16.100 and BIMC 16.20.080. BIMC 16.04 – Environmental Policy The project is subject to the State Environmental Policy Act, as provided in WAC 197-11-800. BIMC 16.12 – Shoreline Master Program The subject property is outside of shoreline jurisdiction. BIMC 16.20 – Critical Areas 280 Madison Avenue North Bainbridge Island, Washington 98110-1812 www.bainbridgewa.gov 206.842.7633 The wetland delineation and categorization provided with the preapplication materials identifies a category IV wetland onsite. Note that under the new CAO, residential development in R-2 zoning adjacent a category IV wetland requires a 40 ft. buffer. The majority of the subject parcel appears to be encumbered by the wetland, buffer, and 15 ft. impervious surface setback from the edge of the buffer. Refer to BIMC 16.20.140.H for standards for specific development, uses, and activities within wetlands and buffers. Compliance with these standards must be demonstrated in application materials (in the critical areas report and mitigation plan, for example), to the extent that they are applicable. It appears that H.1 (private road construction, i.e. driveway) and H.5 (utilities) are applicable to this proposal. Refer to BIMC 16.20.100 for Aquifer Recharge Protection Area requirements. For this project, the ARPA shall include all existing native vegetation on a site, up to a maximum of 65 percent of the total site area. A lower percentage is allowed if necessary to achieve a development area of at least 12,500 square feet on a parcel. The ARPA may include the wetland and wetland buffer. Please show the proposed ARPA on the site plan submitted with RUE application materials. Note that the ARPA shall be documented on a notice to title prior to building permit issuance; this will be a condition of the RUE approval. BIMC 18.09 – Use Regulations Development of single family residences is a permitted use under BIMC 18.09.020. BIMC 18.12 – Dimensional Standards Lot Coverage: 20%* Front Yard Setback: 25 ft. Side Setback: 5 ft. min,15 ft. total** Rear Yard Setback: 25 ft. Max Building Height: 30 ft. *Lot coverage is limited to 1,200 square feet for RUE’s. Lot coverage is defined as: that portion of the total lot area covered by buildings, excluding up to 24 inches of eaves on each side of the building, any building or portion of building located below predevelopment and finished grade. Any portion of a slatted or solid deck located more than five feet above grade shall be counted towards lot coverage. **the applicant is encouraged to establish the minimum side setback from the south lot line. Any alternative, such as that proposed on the application materials submitted with this pre-application conference, must be demonstrated necessary through mitigation sequencing. BIMC 18.15 – Development Standards and Guidelines Development shall comply with the parking standards as set forth in BIMC 18.15.020, which requires two spaces for each primary dwelling unit.

The following LID recommendations apply to the site as it has been presented in the application to reduce vegetation removal, minimize hard surface installation, and mimic natural hydrology. This assessment is non-binding, unless the recommendations are as required under BIMC 15.20. Application for permits with the City of Bainbridge Island for which a SAR is required shall be in substantial conformance with this proposal, or, else a new SAR shall be required. Project Surfaces/Thresholds: Threshold Proposed Project Proposed New/Replaced Hard Surface Total 1,700 SF Proposed Land Clearing/Disturbance 3,600 SF Existing Site Impervious Coverage (0%) Total Site Area 16,117 SF Site Previously Developed Under Adopted Stormwater Regulations (after 2/10/1999) NO Type of Development (New or Redevelopment) Redevelopment Recommendations: • This project proposes to construct an approximate 1,200 SF residence with a 500 SF driveway and an associated on-site septic (OSS) drainfield. Part of the house will be located in a wetland buffer. • An application for a building permit will require the project demonstrate compliance with applicable minimum requirements (MRs) # 1 through 5 of the City’s adopted stormwater manual through development of a Stormwater Site Plan (SSP – MR #1), which is the comprehensive report containing all the technical information and analysis necessary for the City to evaluate a proposed development project for compliance with stormwater requirements. Contents of the SSP will vary with the type and size of the project, and individual site characteristics, and contain site-appropriate development principles, as required, to retain native vegetation and minimize impervious surfaces to the extent feasible. • The project requires a Stormwater Pollution Prevention Plan (SWPPP), also called an Erosion Control Plan (MR #2) that applies to all land-disturbing activities and temporary impacts associated with the project. A well followed SWPPP with established clearing and disturbance limits and clearly thought out phasing helps to minimize unnecessary destruction of healthy soils during the construction process. • The SWPPP should accompany any clearing, grading, or building permit submittal. 280 Madison Avenue N Bainbridge Island, Washington 98110 www.bainbridgewa.gov 206.842.2016 • Temporary construction entrances and access roads shall be constructed of inert materials. Recycled concrete is strictly prohibited. • All soils disturbed and compacted during construction/clearing must be amended to restore soil health to ‘GOOD’ hydrologic conditions by tilling in compost or stripped and stockpiled topsoil where soils allow. • Retaining or planting trees within 20 feet of hard surfaces is recommended to reduce peak stormwater runoff amounts. • Site soils and areas that support infiltration (shown not to meet the infeasibility criteria of the stormwater manual) would require full-downspout infiltration or a rain garden sized per the Rain Garden Handbook For Western Washington meeting the ‘GOOD’ performance standard. Please follow List No. 1 of MR #5 for the required on-site best practices to achieve compliance with the stormwater code for hard surfaces. • The project shall consider utilizing minimal excavation foundation systems per the 2012 Low Impact Development Guidance Manual For Puget Sound as means of minimizing impacts to the site and the adjacent wetlands. A bid comparison/analysis shall be submitted demonstrating the applicant has engaged the appropriate design and construction professionals to explore this foundation system option. The bid shall be obtained from a designer or installer with previous experience building with this technology. • Surface stormwater from driveway and parking surfaces shall receive pre-treatment prior to discharging to the wetlands or leaving the site by directing stormwater to vegetated dispersion strips, rain gardens where soils allow, or the use of permeable pavement (outside of the ROW only), or other alternatives consistent with MR #5, On-Site Stormwater Management of the stormwater manual. • Hardscaping should be constructed of permeable materials or contain wide permeable jointing where feasible to allow infiltration or shallow subsurface filtration of surface stormwater. • Diffuse flow methods (i.e. BMP C206: Level Spreader) should be used to discharge bypass surface stormwater from the adjoining southern lot into the wetland. It is recommended that where a level spreader dispersion trench is utilized to that it be placed a minimum of 25 feet upgradient of the wetland boundary, 50 feet is preferable. • Full-dispersion does not appear to be feasible given that the wetland may not be included as part of the 65% retention area, nor used in the 100-foot overland dispersion path for stormwater management per BMP T5.30 of the stormwater manual. [Note, the wetland may be used as part of the designated 65% Aquifer Recharge Protection Area (ARPA)]. Summary These recommendations are not fully inclusive of all requirements for the site proposal, but represent a comprehensive look at addressing low impact development based on a site specific analysis of the project proposal.

Page 1of 14 Exhibit 7 December 19, 2018 City of Bainbridge Island Planning & Community Development Attn: Anni e Hillier, City Planner 280 Madison Avenue North Bainbridge Island, Washi ngton 98110 RE: Revised Narrative Statement Supporting Reasonable Use Exception Application Euclid Avenue Vacant Parcel,Lot 24,Port Madison On behalf of the applicant, Mr. Mercury Michael,this document presents to the City of Bainbridge Island (CoBI) the reasons for requesting a Reasonable Use Exception (RUE) for the subject property, which is encumbered by a wetland. This application is provided subsequent to the preapplication PLN51139 PR - Michael Single Family Residence (SFR) dated May 8, 2018. The Site Assessment Review (SAR) was completed per SmartGove Case No.: SAR80087 and a SAR letter was provided by CoBI to the applicant as of the same date mentioned above. This application has also been revised to address the "Notice of Incomplete Application" dated September 7, 2018, which follows this narrative statement with the specific pages where the respective responses can be found in this application. Existing Conditions Referring to Figure 1,the followi ng summarizes the existi ng site conditions of the subject parcel: • Approximatel y 16,117 square feet (0.37 acres) in size and situated on the east side of Euclid Avenue Northeast, approximately 200 feet north of the intersection with Northeast Lafayette Avenue. • Located in Section 34, Township 26N, Range 02E, and legally summarized as Lot 24, Plat of Port Madison. • The tax parcel number is 4167-000-024-0003. • Bounded to the west by Euclid Avenue Northeast, and to the north,east and south by lots with SFRs. • The Bainbridge Island Comprehensive Plan designates the subject property zoning as R-2. • The topography generally slopes to the north and east, with a total vertical relief of about 14 feet. • Is undeveloped, and the vegetation consists of a forested canopy within and surrounding a wetland, including deciduous trees (mostly red alder and one maple), lady fern, sword fern,salmonberry, and Indian plum. Invasive vegetation includes English ivy, nettles and non-native blackberries. The red alder trees range in diameter between 12 and 21 inches, and the single maple tree is 43 inches in diameter. • The wetland is situated within the northern portion of the parcel. The center of the wetland is seasonally ponded and fed by the upstream watershed that discharges surface water to the wetl and via a 12-inch diameter culvert beneath Euclid Avenue. The surface Page 2of 14 water then flows to the east through the wetland and exits the property via another 12- inch diameter culvert. • Based on the wetland delineati on (AquaTearra 2018a) and subsequent site civil survey, the wetland is approximately 3,488 square feet (0.08 acres) in size, which is about 22 percent of the total parcel'.The wetland is bounded to the east by the eastern property boundary and coincident fill soil associated with the adjacent parcel. • The wetland was rated based on functions according to the Revised Wetland Rating System for Western Washi ngton {Ecology 2014b) as Category IV, which are regulated according to the Bainbridge Island Municipal Code (BIMC) Critical Area Ordinance (CAO) Title 16.20.160. o The land use impact is high. o Category IV wetlands with a high land use receive a standard buffer width of 40 feet from the delineated edge. o The total buffer width for the wetl and is 40 feet with an additional 15 feet of building setback. o All activities are prohibited within the wetland and its buffer except those specified in BIMC CAO (AquaTerra 2018a). • After applying the wetland buffers, the proposed site development would not be feasible in the absence of the RUE. Referring to Figure 2 through 4, the following summarizes the existing soil conditions and slopes greater 10 percent: • The majority of the parcel is mapped as underlain by McKenna gravelly loam (USDA 1980). The stated properties and qualities are as follows: o Slope: O to 6 percent o Depth to restrictive feature: 20 to 39 inches to densic material o Natural drainage class: Poorly drained o Capacity of the most limiting layer to transmit water (Ksat): Very low to moderately low (0.00 to 0.06 in/hr) o Depth to water table: About O to 6 inches o Frequency of flooding: None o Frequency of ponding: Frequent o Available water storage in profile: Low (about 3.7 inches) • The southeastern corner of the parcel is mapped as underlain by Kapowsin gravelly ashy loam (6 to 15 percent slopes) (USDA 1980). The stated properties and qualities are as follows: o Slope: 6 to 15 percent o Depth to restrictive feature: About 29 inches to densic material;About 25 inches to cemented horizon o Natural drainage class: Moderately well drained o Capacity of the most limiting layer to transmit water {Ksat): Very low {0.00 to 0.00 in/hr) o Depth to water table: About 11to 24 inches o Frequency of flooding: None 1The northern wetland boundary was not delineated. However, the southern delineated boundary approximately follows the 36 foot topographic contour so the northern boundary is shown continuing in this fashion Page 3of 14 o Frequency of ponding: None o Available water storage in profile: Low (about 5.3 inches) • The entire parcel is mapped by the U.S. Geological Survey (Haugerud 2005) as underlain by Vashon till, which is typically "glacially consolidated, low-permeability unit comprising unstratified clay, silt, cobbles and boulders with ubiquitous coarse-grai ned lenses and is an extensive surficial unit throughout the south-central Puget Lowland" (Knoedler 2014). • The slopes outside the wetland are generally more than 10 percent, but generally less than 15 percent. Isolated slopes are as steep as about 32 percent. Proposed Site Development The following summarizes the proposed site development: • The applicant proposes to construct a two-three story 1,200 square foot single-family residence (SFR) with a 500 square foot driveway and associated on-site septic (OSS) drainfield (Figures 3 through 5). • The proposed site development would incorporate all recommendations presented in the SAR review letter to allow reasonable use of the property; the recommendations were as follows: o The application for a building permit would include demonstrated compliance with applicable minimum requirements (MRs) 1through 5 of the City's adopted stormwater manual through development of a Stormwater Site Plan (SSP) (MR 1), which is the comprehensive report containing all the technical information and analysis necessary for the City to evaluate a proposed development project for compliance with stormwater requirements. MRs 1through 5 are as follows: • MRl- Preparation of SSPs' • MR2 - Construction Stormwater Pollution Prevention (SWPP)3 • MR3 - Source Control of Pollution • MR4 - Preservation of Natural Drainage Systems and Outfalls • MRS - On-site Stormwater Management, including Applicable Best Management Practice (BMP) T5.14A: Rain Gardens. o It is understood that the contents of the SSP would vary with the type and size of the project, and individual site characteristics, and contain site-appropriate development principles, as required, to retain native vegetation and minimize impervious surfaces to the extent feasible. o A Stormwater Pollution Prevention Plan (SWPPP), also called an Erosion Control Plan (MR2), would be prepared to address all land-disturbing activities and temporary impacts associated with the project. • A well followed SWPPP with established clearing and disturbance limits and clearly thought out phasing would minimize unnecessary destruction of healthy soils during the construction process. 2 MRl - Preparation of SSPs would normally not apply because the 2,000 square feet threshold for hard surfaces and 7,000 square feet for land disturbances would not be exceeded. However, the applicant would implement the SAR letter-related recommendation to prepare the SSPs. 3 MR2 - Preparation of Construction SWPP would normally not apply because the 2,000 square feet threshold for hard surfaces and 7,000 square feet for land disturbances would not be exceeded,but the project would at a minimum consider all 13 Elements of Construction Stormwater Pollution Prevention and develop controls for all elements that pertain to the project site (Ecology 2014a). Page 4of 14 • The SWPPP would accompany any clearing,grading, or building permit submittal. o Temporary construction entrances and access roads would be constructed of inert materials. Recycled concrete would be prohibited. o All soils disturbed and compacted during construction/clearing would be amended to restore soil health to 'GOOD' hydrologic conditions by tilling in compost or stripped and stockpiled topsoil where soils allow. o Retaining or planting trees within 20 feet of hard surfaces would be implemented to reduce peak stormwater runoff amounts. o Site soils and areas that support infiltration (shown not to meet the infeasibility criteria of the stormwater manual) would include full-downspout infiltration (splash blocks) combi ned with permeable pavement". List No. 1of MRS would be implemented for the required on-site best practices to achieve compliance with the stormwater code for hard surfaces. o The project would utilize minimal excavation foundation systems per the 2012 Low Impact Development Guidance Manual for Puget Sound as means of minimizing impacts to the site and the adjacent wetlands. A bid comparison/analysis would be submitted demonstrati ng the applicant has engaged the appropriate design and construction professionals to explore this foundation system option. The bid would be obtained from a designer or installer with previous experience building with this technology. o Surface stormwater from driveway and parking surfaces would receive pre- treatment prior to discharging to the wetlands utilizing permeable pavement (outside of the ROW only), or other alternatives consistent with MRS, On-Site Stormwater Management of the Stormwater manual. o Hardscaping would be constructed of permeable materials or contain wide permeable jointi ng where feasible to allow infiltration or shallow subsurface filtration of surface stormwater. o Diffuse flow methods (i.e. BMP C206: Level Spreader) would be used to discharge bypass surface stormwater from the adjoining southern lot into the wetland. The level spreader dispersion trench would be placed 2S to SO-plus feet upgradient of the wetland boundary. o Full-dispersion would likely not be feasible given that the wetland may not be included as part of the 6S percent retention area, nor used in the 100-foot overland dispersion path for stormwater management per BMP TS.30 of the stormwater manual. However, the wetland would be used as part of the designated 6S percent Aquifer Recharge Protection Area (ARPA). • To minimize adverse impacts to the wetland, the SFR is proposed to be constructed in the southwesternmost corner of the parcel (Figure 3). • The proposed development would incorporate a Low Impact Development (LID) approach to minimize ground disturbance and excavations, especially where wetland setbacks would be encroached upon. 4 Due to the site civil survey determining that the site slopes are steeper than mapped by the Bainbridge Island GIS maps, it was determined that a rain garden sized per the Rain Garden Handbook for Western Washington meeting the 'GOOD' performance standard was not feasible. Page 5of 14 • The type of proposed foundation support would minimize the amount of excavation and ground disturbance needed. Pin piles or piers are proposed for foundation support within the designated wetland buffer and building setback area, which would result in minimal excavation and/or ground disturbance (Figures 3 and 4). • The site development would require a new right-of-way access to Euclid Avenue, and transportation impact fees (TIF) would be applied. An approximately 500 square foot driveway would be constructed between Euclid Avenue and the SFR garage (Figures 3 and SJ. • The site is not located within the COBI water or sewer service areas and would therefore require an OSS. The septic tank and related features would be installed south of the proposed SFR, and the drain field would be installed to the east of the SFR (Figures 5 and 6). o The primary drainfield would avoid both the wetland buffer and building setback buffer. o The reserve drainfield would be within the building setback buffer but avoid the wetland buffer. o Both the primary and reserve drainfields would be situated apparently cross- gradient to the onsite wetland. Therefore, groundwater discharge from the septic drainfields would likely not impact the onsite wetland. • Four red alder trees ranging in diameter from 13 to 16 inches would need to be removed to allow the constructi on of the SFR and related site development (Figure 1). All four trees are outside the wetland buffer area. Existi ng invasive plants (primarily English ivy, nettles and non-native blackberry) would be removed and wetland mitigation planting with native vegetation would be implemented per the wetland Mitigation Plan to enhance the existing wetland function (AquaTerra 2018b). • A 16-foot-wide building setback area would be established between the SFR and the southern property boundary to allow the installation of the septic system and provide for a critical construction-related staging area. No other areas are available onsite outside the wetland and related buffers, or within the immediate proximity of the site, for construction-related staging. Criteria and Applicant Responses for the Review and Approval of the RUE The following are the eleven criteria for the review and approval of an RUE {BIMC Title 16, Section 16.20.080), all of which have been addressed by the proposed site development as presented in the above narrative and attached supporting documents. Responses describing how the proposed site development would address each decision criterion are also presented: 1. The application of this chapter would deny all reasonable use of the property. o After applying the wetland buffers, the proposed site development would not be feasible in the absence of the RUE. o All reasonable use of the property would be denied per the application of the BIMC Title 16, Section 16.20, under other forms of application for SFR construction on the subject parcel. 2. There is no reasonable alternative to the proposal with less impact to the critical area or its required buffer. Page 6of 14 o As described above under Proposed Site Development, the proposed site development has been minimized to the least reasonable extent and designed to mitigate impacts to the wetland, and may improve the function of the wetland when compared to the exi sting conditions due to the implementation ofthe Mitigation Plan (AquaTerra 2018b) and the diversion of stormwater from the adjacent parcel to the south to the wetland. 3. The proposal minimizes the impact on critical areas in accordance with mitigation sequencing {BIMC 16.20.030). o The proposed site development would include the following actions to minimize impacts to the wetland and buffer in accordance with mitigation sequencing: • Low impact fencing between the SFR and wetl and buffer,and signage to prevent future encroachment; • Plants between SFR and wetland would be chosen based on their ability to provide light and noise screeni ng,i.e. densely planted trees/hi gh stature shrubs; • Using elevated walkways around the SFR within the wetland buffer, rather than at-grade; • Directing lights away from the wetland; • Low-impact foundation designs; • Establish covenants to avoid the use of pesticides within the parcel; • Disperse stormwater runoff from the adjacent parcel to the south into the wetland; and • Utilize full-downspou t infiltration (splash blocks) combined with permeable pavement to disperse stormwater collected from the SFR- related roof and driveway into the near-surface soil upgradient of the wetland. • Other actions described above under Proposed Site Development, including the SAR letter recommendati ons. 4. The proposed impact to the critical area is the minimum necessary to allow reasonable use of the property. o The proposed site development has been reduced to the extent practicable utilizing best avai lable science for mitigati ng adverse impacts to the envi ronment through the implementation of actions presented in the Mitigation Plan (AquaTerra 2018b), SAR letter recommendations,and BMPs. 5. The inability of the applicant to derive reasonable use of the property is not the result of actions by the applicant, or of the applicant's predecessor, that occurred after February 20, 1992. o The applicant and the applicant's predecessor did not engage in property- related actions after February 20, 1992. Page 7of 14 6. The proposed total lot coverage does not exceed 1,200 square feet for residential development. o The proposed SFR footpri nt woul d not exceed 1,200 square feet. 7. The proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the property. o The proposed site development would not pose an unreasonable threat to the public health, safety, or welfare on or off the property through the implementation of actions presented inthe Mitigation Plan (AquaTerra 2018b), SAR letter recommendations, and BMPs. 8. Any alterations permitted to the critical area are mitigated in accordance with mitigation requirements applicable to the critical area altered. o The proposed site development would mitigate impacts to the wetland area through the implementati on of actions presented in the Mitigation Plan (AquaTerra 2018b), SAR letter recommendati ons, and BMPs. 9. The proposal protects the critical area functions and values consistent with the best available science and results in no net loss of critical area functions and values. o The proposed site development would protect the critical area functions and values consistent with the best available science and results in no net loss of critical area functions and values through the implementation of actions presented in the Mitigation Plan (AquaTerra 2018b), SAR letter recommendations, and BMPs. 10. The proposal addresses cumulative impacts of the action. o The proposed site development would address cumulative impacts through the implementation of actions presented inthe Mitigation Plan (AquaTerra 2018b), SAR letter recommendations, and BMPs. The parcel to the west and upgradient of the subject property is owned by the Port Madison Water Company and it is our understanding would not be developed in the future. All other adjacent parcels have been developed. Therefore, no adverse cumulative impacts are anticipated within the foreseeable future. 11. The proposal is consistent with other applicable regulations and standards. o The proposed site development would be consistent with all relevant and applicable regulations and standards. Summary of Reasons for RUE Request Per the CoBI Administrative Manual Planning Permit Submittal Requirements, and the documents received during the Pre-Appl ication meeting,the followi ng summarizes the reasons for requesting the RUE: • Per the applicati on of BIMC Chapter 16, Section 16.20, under other forms of application for SFR construction on the subject parcel,all reasonable use of the property would be denied. • Upon review and consideration by all the professionals engaged for this project (including architect, wetlands biologist, civil engineer, and septic designer), the collaborative Page 8of 14 #Br Mtltaet evaluation of the parcel has shown the RUE be the only viable alternative to allow construction of a SFR on the subject parcel,considering the wetland-related constraints. • The inability of the applicant to derive an expected and reasonable use at this subject parcel is not due to any actions of the applicant or the current seller (applicant's predecessor). • The proposed development would not pose an unreasonable threat to the health,safety, or welfare, on or off the subject property, and off-site mitigation would not be required. • The proposed development is consistent with all relevant and appl icable regulations and standards, including all eleven above-mentioned criteria for considering the approval of an RUE.

The property is 0.37 acre in size. It belongs to Larry Pritchard and is located in Section 34, Township 26N, Range 02E. The wetland is located in the northern portion of the subject property. The purpose of the wetland delineation was to establish the wetland boundary and its associated buffer for a future structure. The parcel slopes down to the north towards the wetland. There are no existing structures on the property. The vegetation consists of a forested canopy surrounding the wetland. The remainder of the property is consists of a few alders, shrubs, and herbaceous species. There is one existing wetland that is located on the northern property boundary. The center of the wetland is seasonally ponded and has a permanently flowing outlet. The outlet is a culvert through which the water flows to the east and exits the property. It is unknown where the water travels to the surface again. A second culvert crosses under Euclid Ave NE, feeding the wetland. NRCS Soil Survey The Natural Resources Conservation Service (NRCS) Soil Survey shows one type of soil on the subject property: 32-McKenna gravelly loam. Norma soil is a 10 percent minor component of the soil type and known as a hydric soil. National Wetland Inventory (NWI) The US Fish and Wildlife Service NWI mapper does not show the onsite wetland. There are four other wetlands within a mile of the subject wetland. The subject wetland is within 0.1 mile from the Puget Sound. None of the wetlands shown on the mapper tool are associated with the onsite wetland. The City of Bainbridge Island (COBI) GIS mapper shows the onsite wetland. The COBI mapper has several wetlands within a mile of the subject property. None of them are associated with the subject wetland. Page 3 of 4 Wetland Delineation Methodology for a routine wetland delineation was used in accordance with guidelines in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region Version 2.0 (US Army Corps of Engineers 2010). Fieldwork was conducted on February 5, 2018 under cloudy skies and approximately 50°F temperatures. The property is accessed from Euclid Ave NE. There is one depressional wetland in the northern portion of the property (Figure 2). The onsite wetland vegetation is a forested canopy with emergent vegetation. Pink flagging tape was used to mark the wetland edge and labeled W-1 through W-7 (Figure 2). The onsite wetland vegetation is a forested classification. It consists of red alder (Alnus rubra), English ivy (Hedera helix), lady fern (Athyrium filix-femina), salmonberry (Rubus spectabilis), sword fern (Polystichum munitum), and Indian plum (Oemleria cerasiformis). No signs of recent disturbance were noted. Therefore the delineation was done on the basis of the existence of normal circumstances on the site. Two data points were dug. The first data point (Test pit 1) was dug 10 feet north of flag W-3, a second data point (Test pit 2) was dug uphill of the wetland, just south of flag W-3. The vegetation surrounding Test pit 1 was dominantly hydrophytic. The soils met the parameters for hydric soils. The soil was found to be a silty loam with a Munsell reading of 10YR 2/1 and no redoximorphic features from 0-6 inches below the surface. The soil from 6-21 inches was a loam with a Munsell reading of 10YR 4/1 with 10% soft masses (10YR 4/6). There was water in the pit to 8 inches below the surface and the soil was saturated to the surface (See Data Forms in Appendix A) The vegetation surrounding test pit 2 was not dominantly hydrophytic. The soil did not meet the parameters for hydric soils. The soil was found to be a loam with a Munsell reading of 10YR 3/3 and no redoximorphic features from 0-22 inches below the surface. There were no signs of hydrology present (See Data Forms in Appendix A). Page 4 of 4 Wetland Rating The wetland was rated based on functions provided by the wetland according to the Revised Wetland Rating System for Western Washington (Ecology 2014). The hydrogeomorphic classification for the wetland is depressional and was rated as a depressional wetland. The overall score for the wetland is 14, making it a Category IV wetland. The water quality function score is 6 and the hydrologic function score is 4. The potential for providing habitat function is 5. (See Rating Form in Appendix B) Category IV wetlands are regulated according to Bainbridge Island Municipal Code (BIMC) Critical Area Ordinanace (CAO) Title 16.20.140. The land use impact is moderate. Category IV wetlands with a moderate land use receive a standard buffer width of 40 feet from the delineated edge (CAO 16.20.140, Table 6). The total buffer width for the wetland is 40 feet with an additional 15 feet of building setback. All activities are prohibited within the wetland and its buffer except those specified in BIMC CAO. Summary There was one freshwater wetland found on the southern portion of the property. The wetland was delineated on parcel 4167-000-024-0003. The wetland is rated as a Category IV wetland and regulated under the Bainbridge Island Municipal Code and Critical Area Ordinance. Category IV wetlands with moderate land use receive a buffer total of 40 feet. The total wetland buffer will be 40 feet with an additional 15 foot building setback from the delineated edge of the wetland.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go 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 If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. 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). NO – 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. For questions 1-7, the criteria described must apply to the entire unit being rated. 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. Wetland Rating System for Western WA: 2014 Update Rating Form – Effective January 1, 2015 4 Wetland name or number 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 some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland 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. 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 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 If you 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 property belongs to Larry Pritchard. It is 0.37 acres in size and is located in Section 34, Township 26N, Range 02E. The wetland is located in the northern portion of the subject property along the property boundary. A wetland delineation was conducted in 2018. The purpose of this mitigation plan is to apply for a Reasonable Use Exception (RUE) for a future single family residence. The majority of the property is encumbered by the wetland and its buffer. The applicant has designed a building plan that will avoid the greatest amount of impact to the wetland and its buffer. Existing Conditions The parcel is located on the eastern side of Euclid Drive NE. It slopes down to the north toward the existing wetland. There are no existing structures on the property (Figure 2). The property consists of undisturbed vegetation. The northern portion of the property is a forested canopy with a small seasonal ponding area. There is a seasonal stream that flows out of the ponding area to the east. The seasonal stream continues on to the eastern adjacent property. The southern portion of the property consists of groundcover and herbaceous vegetation. A fair amount of the center of the property is encumbered by English ivy (Hedera helix). The herbaceous vegetation in the northern portion is mainly dead nettle (Lamium galeobdolon), an invasive species. The onsite wetland is regulated by Bainbridge Island Municipal Code (BIMC). Project Description The wetland and its buffer cover the majority of the parcel. Plans for the construction of a single family residence will be submitted with a building permit. The building will be situated on the Page 3 of 6 property to minimize the impact to the buffer and be as far away from the wetland as practicably possible considering the need for a 15- to 20-foot-wide staging area between the building and southern property boundary during construction. The single family residence will have a 1200 square foot footprint to meet the RUE regulations of no larger than a 1200 square foot footprint (BIMC 16.20.080). A driveway will be installed to access the single family residence from Euclid Ave. A significant portion of the property is covered with English ivy (Hedera helix) and dead nettle (Lamium galeobdolon). It is recommended to remove the English ivy and dead nettle to be replanted with native vegetation (listed below). Environmental Goals and Objectives It is the goal of this mitigation plan to uphold the function and value of the wetland and its buffer. There will be no net loss of wetland function due to the construction of a single family residence. Much of the existing buffer consists of non-native plant species, English ivy (Herdera helix) and dead nettle (Lamium galeobdolon). The removal of this low lying invasive vegetation will benefit the wetland habitat. The function and value of the buffer will only increase by replacing the invasive species with native shrubs and trees. The native vegetation will provide a dense vegetation buffer for wildlife. The planting area includes the area between the single family residence and the wetland. This area in particular is important to remove invasive species in order to minimize the impact of the single family residence on the wetland. The effects to the wetland will be best minimized by replacing the current ground-cover vine and herbaceous vegetation. Minimization and Mitigation Measures Minimization/Avoidance for Temporary Impacts During the course of the restoration, standard best management practices (BMPs) will be implemented. These BMPs include, but are not limited to: • Installing appropriate sedimentation and erosion control where necessary, such as silt fencing Page 4 of 6 • Plant buffer with dense vegetation • Minimize light pollution by directing lights away from the wetland • Minimize noise impacts by placing noise generating equipment away from the wetland • All toxic materials to be kept out of the wetland and its buffer • Prevention of all materials and debris of entering the wetland and its buffer • Keeping noise and artificial light to minimum, artificial light should be directed away from the wetland when possible Mitigation for Permanent Impacts In order to mitigate for loss of vegetation from the impacted area, native plants will be installed. All invasive vegetation will be removed prior to the planting process. English ivy and dead nettle are the primary invasive vegetation. Once the invasive vegetation is removed, mulch will be added to help prevent the re-establishment of invasive species and promote the growth of the planted native species. Regulatory Requirements The impacted portion of the buffer will be no greater than 1200 square feet which will be replanted at a ratio of 1.5:1. This is in accordance with 16.20.140 Table 8. This will require a total of 1800 square feet of buffer restoration. Planting must occur during the spring or autumn seasons in order to promote the survival of new vegetation. Therefore, planting will be implemented October through November or March through June. Plants can be bare root or potted. If planting is implemented during the fall, all plants must be watered when there has been no precipitation for 2 days for a full year. If planting is implemented in the spring, watering must occur when there has been no precipitation for 2 days. In both cases watering will continue every other day while no precipitation occurs. Restoration and Enhancement When construction is completed and the blackberries have been removed at least 3 inches of mulch will be laid down to promote vegetation growth and deter growth of invasive species. All invasive species in the section of the buffer to be re-established will be removed by hand. The following are recommended species to be planted within the restored area: Page 5 of 6 Common Name Latin Name Size Spacing Quantity Western red cedar Thuja plicata 3 gal 15 ft 2 Red alder Alnus rubra 3 gal 15 ft 5 Salmonberry Rubus spectabilis 1 gal 6ft. 20 Indian plum Oemleria cerasiformis 1 gal 6ft 10 Sword fern Polystichum munitum 1 gal 3ft. 20 Lady fern Athyrium filix femina 1 gal 3ft 20 The approximately 1800 square feet of restored buffer is highlighted within the red polygon in figure 3. Monitoring Program The re-established area will be monitored for no less than 7 years. This is in accordance with BIMC 16.20.180.G. No less than 7 sample plots will be randomly chosen after the project is completed. These sample plots will be photographed every year and submitted to the City of Bainbridge Island to demonstrate the success of the planted vegetation. Performance Standards, Maintenance, and Contingency Plan All restoration and enhancement will be completed within the compliance of the mitigation plan (BIMC 16.20.180.G). In the first year, all planted vegetation will have 100% survival and the removed invasive vegetation should have a coverage of less than 20%. Vegetation survival should be at least 80% for the second year and at least 75% of the original planting for the third year. Every year after, the survival shall be no less than 75% of the original as built mitigation plan. If the percentage of surviving plants falls below the required amount, the vegetation shall be replaced at the expense of the applicant. The applicant shall demonstrate financial resources required to complete the scope of this mitigation plan. Page 6 of 6 Summary A category IV wetland and its buffer encompass the majority of the subject property. The property qualifies for a reasonable use exception permit. A single family residence with no more than a 1200 square foot footprint, with proper minimization and mitigation, will be allowed to be built on the property (BIMC 16.20.080). The applicant will minimize the impact to the wetland and its buffer and restore the buffer by implementing the mitigation plan presented above.

SOURCE OF BOUNDARY AND TOPOGRAPHY: ADAMS, GOLDSWORTHY OAK, 9/28/2018. 1 Annie Hillier From: Ann Hillier Sent: Thursday, December 20, 2018 9:44 AM To: Rik Langendoen Subject: RE: Response to PLN51139 RUE Euclid House RUE Thank you, Rik. I’ve received all of the documents. Now that the wetland boundaries have been surveyed and the wetland appears to occupy a bit less area on the project site, I thought that a buffer width reduction might be an option. Buffer modification allows the buffer width to be reduced up to 25% for a home site, and septic facilities could go in the buffer with a critical areas permit if necessary. This would be a less expensive and faster permit process, with no hearing, so I wanted to make sure that it has been considered. In fact, an applicant is required to first consider this option, but the previously mapped wetland boundary made it seem infeasible. Here is the buffer modification section, taken from BIMC 16.20.140: 8. Buffer Modification. On each site, only one of the following modifications to buffer widths may be allowed provided the applicant demonstrates the need for modification through mitigation sequencing pursuant to BIMC 16.20.030 and the modification that results in the retention of the greatest area of buffer is used. a. Buffer Width Averaging. The width of a required buffer may be averaged if the applicant can demonstrate that averaging can provide equal or greater functions and values as would be provided under the required buffer and all of the following conditions are met: i. The total area of buffer after averaging is equal to the area required without averaging. ii. Averaging cannot result in any portion of the buffer being reduced more than 25 percent of its required width. b. Buffer Width Reduction. The width of a required buffer may be reduced if the applicant can demonstrate that the reduction will provide equal or greater functions and values as would be provided under the required buffer and that this will improve the protection of wetland functions and all of the following conditions are met: i. The buffer may not be reduced more than 25 percent of its required width. ii. Native vegetation on other portions of the site is retained in order to offset habitat loss from buffer reduction. After playing around with the site plan, it seems like this still might not leave enough of a homesite area (even if the front setback were reduced), but I would love your thoughts. Please let me know what you think, and if you have any questions, do not hesitate to reach out. If we need to proceed with the RUE, then I will be going through the RUE completeness review over the next two weeks and will let you know what the outcome is. We will discuss a hearing date once the application is deemed complete. During the 120-day review process, it is common for the City to reach out with recommended revisions. I will try to send those to you as early on in the review process as possible. Thanks very much and I look forward to hearing from you, 1 Annie Hillier From: Rik Langendoen <rik.langendoen@gmail.com> Sent: Thursday, December 27, 2018 4:09 PM To: Ann Hillier Subject: Re: Response to PLN51139 RUE Euclid House RUE Annie, As noted in my voice mail message a moment ago, I am back from home after holiday travels.

Mercury and I had several questions following up with the telephone conversation you and I had last week in order to better understand whether a single family residence could be constructed without requiring an RUE. Assuming we are able to demonstrate that the wetland function of the developed parcel would be equal to or greater than the pre-site development-related conditions: 1. Would the 15’ building setback from the wetland buffer still apply? Yes, the 15 ft. setback still applies. The code reads: “A structure or hard surface setback line of 15 feet is required from the edge of any wetland buffer. Minor structural or impervious surface intrusions into the areas of the setback, such as but not limited to fire escapes, open/uncovered porches, landing places, outside walkways, outside stairways, retaining walls, fences and patios, may be permitted if the department determines upon review of an analysis of buffer functions submitted by the applicant, that construction and/or maintenance of such intrusions will not encroach into the wetland buffer or adversely impact the wetland. The functional analysis shall include a functional methodology supported by best available science. The setback shall be identified on a site plan and filed as an attachment to 2 the notice on title as required by BIMC 16.20.070.G (Notice on Title).” If this still leaves too little of a building envelop, we can also see if reducing the front setback would help any (minor variance) – it looked like there was unencumbered area along the front lot line. 2. Would it be possible to allow a larger septic system (i.e. 3 or 4 bedroom) if the RUE is not required? This is subject to health district approval, but I would think yes. The septic system would have to be located outside of the buffer to the extent possible, and then if it is necessary to utilize the buffer, you would need to meet the standards under 16.20.140.H.5 (for utilities) and mitigate for any permanent impacts (to be described in wetland mitigation plan). We would process this as a major critical areas permit, but it would be reviewed through the building permit. The septic system would be allowed in the 15 ft. setback from the buffer without a critical areas permit, provided it is demonstrated that the buffer/wetland will not be impacted. 3. What would be the anticipated permitting-related time frame? If only buffer modification is requested, then we would review the buffer enhancement/mitigation plan with the building permit, which can take anywhere from 10-16 weeks. If buffer modification and a major critical areas permit is requested, we can still do concurrent review with the building permit, but we would follow different administrative review procedures, which can take up to 120-days. Fees: RUE – $3,816 (already paid for; refund issued if application is cancelled) Buffer modification only - $1,526 Buffer modification and critical areas permit - $2,034.67 Buffer modification and minor variance - $3,942.67 The fees should not be used in making a decision as to which permit to apply for, but it is still valuable information. The decision should come down to whether buffer modification is feasible on the site, either with another permit or not. If it isn’t, then we should proceed with the RUE. I’m very sorry that we did not go into this detail during the pre-app phase – again, at that point the wetland boundaries seemed to occupy more of the site. If you do decide to adjust the site plan and apply for something other than the RUE, I can sit down with you to go over any submittal items that need to be adjusted. I do not think it would be much… I’m curious what your thoughts are after digesting all this – let me know when you are ready to discuss. Thank you! -Annie Thank you.

A determination of a complete application does not preclude the department from requesting additional information or studies. Please consider the following: • The City recommends that the SFR and septic tanks be reversed, with the SFR setback the minimum distance (5 ft.) from the south lot line and the septic tanks located immediately north of the SFR. o This would allow for the standard 15 ft. impervious surface setback between the SFR and the mitigation area edge (with septic tanks located between), helping to prevent future encroachment into the mitigation area than if it were directly abutting the SFR. o This would also allow for construction staging area within the 15 ft. setback. o Finally, the City bases its recommendation to the hearing examiner off the proposal’s compliance with the RUE review criteria in BIMC 16.20.080. Placing lower impact development (i.e. buried septic tanks with vegetation/lawn above) within the existing wetland buffer and closest the wetland edge, as opposed to the SFR which represents a permanent, substantial impact, would demonstrate compliance with RUE review criteria #3 and #4. o Please see the attached document, illustrating this comment. o If this is infeasible, please provide detailed information for staff to relate to the hearing examiner. • Please provide the proposed total impact to the wetland buffer, including any area necessary for access and maintenance around the SFR. • Please note that the following information is missing from the wetland report: o a map of the ‘Hydroperiods’ is needed to answer question D1.4 and H1.2 o a map of the ‘Boundary of area within 150 ft of the wetland’ is missing from figure 3 and is needed to answer question D2.2 and D5.2 o a map of the ‘Cowardin plant classes’ is missing from figure 4 and is needed to answer question D1.3, H1.1 and H1.4 City of Bainbridge Island Department of Planning & Community Development 280 Madison Avenue North, Bainbridge Island, WA 98110 Phone: 206-842-2552 Email: pcd@bainbridgewa.gov Website: www.bainbridgewa.gov Portal: https://ci-bainbridgeisland-wa.smartgovcommunity.com/portal o the math is not shown on question H2.1 or H2.2 o question H2.3 needs to be justified o the impact of land use is incorrect (it is considered moderate) It does not appear that this information will impact the rating of the wetland or its boundaries, so the City will continue to process the application based on the information provided.

The applicant received a Notice of Complete Application (NoCA) from CoBI dated January 2, 2019 in which CoBI requested consideration of an alternative that consists of reconfiguring the locations of the proposed single-family residence (SFR) and associated infrastructure presented in the above-mentioned RUE application. If the alternative was found to be infeasible, CoBI requested detailed information for staff to relay to the RUE-related hearing examiner. This technical memorandum presents the requested detailed information. The following presents a brief summary of both the applicant’s proposed site development and the alternative presented in the NoCA, and then the results of an alternatives assessment that compares the two different approaches and their respective anticipated outcomes. SUMMARY OF APPLICANT’S PROPOSED SITE DEVELOPMENT As presented in the Narrative Summary submitted to CoBI in the above-mentioned RUE application, the subject parcel is constrained by a Category IV wetland. After applying the relevant 40-foot-wide wetland buffer and associated 15-foot-wide building setback per the Bainbridge Island Municipal Code (BIMC), there is insufficient space available for the construction of the proposed SFR with a 1200-square-foot footprint, associated required infrastructure (on-site septic (OSS) system, stormwater drainage system, combined driveway / off-street parking), and construction-related staging unless an RUE is approved (Figures 1 and 2). In addition, the subject parcel has a total vertical relief of about 12 to 14 feet, which creates challenges in terms of providing foundation support for the SFR and related infrastructure without impacting the wetland. In summary, and as discussed in more detail in the above-mentioned Narrative Summary, the proposed site development would incorporate all recommendations presented in the CoBI Site Assessment Review (SAR) review letter dated May 8, 2019 to allow reasonable use of the property, including the following key elements: • The application for a building permit would include demonstrated compliance with applicable minimum requirements (MRs) 1 through 5 of the City’s adopted stormwater manual through development of a Stormwater Site Plan. Page 2 of 8 • Site soils and areas that support infiltration would include full-downspout infiltration (splash blocks) combined with permeable pavement1. • Surface stormwater from driveway and other hard surfaces would receive pre- treatment prior to discharging to the wetlands utilizing permeable pavement. • The project would utilize minimal excavation foundation systems per the 2012 Low Impact Development Guidance Manual for Puget Sound as means of minimizing impacts to the site and the adjacent wetlands, which would include pin piles or piers (https://www.diamondpiers.com/how-it-works). Therefore, negligible fill placement and/or ground disturbance would occur within the wetland buffer and building setback area. • To minimize adverse impacts to the wetland, the SFR is proposed to be constructed in the southwestern corner of the parcel (Figure 1). The house would be cantilevered from the street level utilizing the pin piles or piers, creating a 10 to 12 feet vertical separation from the ground surface (Figure 2) with no stairway or other direct access to the wetland mitigation area, wetland buffer and wetland, which would prevent encroachment and demonstrate compliance with RUE review criteria 3 and 4 to the extent practicable considering the site constraints. • The proposed site development has been minimized to the least reasonable extent and designed to mitigate impacts to the wetland, and may improve the function of the wetland when compared to the existing conditions due to the implementation of the Mitigation Plan2 and the diversion of stormwater from the adjacent parcel to the south to the wetland. The need for the OSS system creates several challenges in terms of the proposed site development. Due to site constraints associated with the wetland-related buffer, topography, and soil conditions, the OSS would require a buried pressurized system that would include two tanks and mechanical components consisting of wastewater treatment and air blower, in addition to the drainfield. The OSS-related tanks and mechanical system cannot be realistically installed on a slope without fill placement due to the need for vehicle access for maintenance and possible repair after installation. Therefore, these components are proposed to be installed between the SFR and southern property boundary, as highlighted on Figure 1. The OSS tanks and mechanical system installation would be at or near the existing site grades. The 16-foot wide alleyway created by the underground OSS tanks and mechanical system would also allow for vehicle and equipment access to the primary and reserve drainfields for maintenance and possible repair after installation (Figure 1), as well as provide a critical staging area during the construction of the SFR. 1 Due to the site civil survey determining that the site slopes are steeper than mapped by the Bainbridge Island GIS maps, it was determined that a rain garden sized per the Rain Garden Handbook for Western Washington meeting the ‘GOOD’ performance standard was not feasible. 2 Existing invasive plants (primarily English ivy, nettles and non-native blackberry) would be removed and wetland mitigation planting with native vegetation would be implemented to enhance the existing wetland function. Page 3 of 8 SUMMARY OF ALTERNATIVE PRESENTED IN NOCA As described in the above-mentioned NoCA, and as shown on Figures 3 and 4, the recommended alternative to the site development layout includes reversing the SFR and OSS in the north-south orientation, with the SFR setback the minimum 5-foot distance from the southern property boundary/lot line, and the OSS situated north of the SFR. The intent was to: • Allow for the standard impervious surface setback between the SFR and the wetland mitigation area edge, with the OSS tanks and mechanical components located between the SFR and the wetland mitigation area edge, and to help prevent future encroachment into the wetland mitigation area. • Provide a construction staging area within the 15-foot impervious surface setback area. • Improve on compliance with RUE criteria 3 and 4 as presented in the BIMC 16.20.0803 by placing lower impact development (i.e. buried septic tanks and mechanical components) with vegetation/lawn at the ground surface within the wetland buffer and closest the wetland edge. The alternative as presented in the NoCA would be feasible and likely achieve the above-mentioned intent if the subject parcel was flat lying with minimal topographic relief. However, due to the roughly 12 feet of topographic relief the alternative would require on the order of 700-plus cubic yards of fill soil placement within the wetland buffer and mitigation area, and possibly encroach upon the wetland4. Therefore, the mitigation area would be reduced in size by roughly 30-plus percent. The fill would need to be imported and compacted in order to prevent post-construction settlement and possible damage to the OSS-related piping and prevent erosion. It may be possible to construct retaining walls to reduce the amount of fill placement, but the retaining walls and related fill soil placement would need to occur within the wetland buffer and reduce the size of the mitigation area. ALTERNATIVE ASSESSMENT RESULTS & COMPARISON In summary, the alternative recommended in the NoCA would be feasible and effective at achieving the intended outcomes if the site was flat lying. However, when the site topographic relief is considered the alternative would likely result in significant adverse impact to the wetland due to the need to add significant quantities of fill soil and/or retaining walls. The alternative would likely not comply with RUE criteria 3 and 4 as intended. In comparison, the applicant’s proposed site development would include negligible if any fill placement within the wetland buffer and building setback area, and minimal ground disturbance due to use of low impact pin piles or piers for foundation support of the SFR. Because the SFR would be cantilevered from the street level utilizing columns placed on pin piles or piers, thereby creating a 10 to 12 feet vertical separation with no stairway or other direct access to the wetland mitigation area, wetland buffer and wetland, it would prevent encroachment and demonstrate compliance with RUE review criteria 3 and 4 to the extent practicable considering the site constraints. The following table summarizes the comparison between the applicant’s proposed site development and NoCA-related alternative. 3 See BIMC 16.20.080, criteria 3 and 4, and BIMC 16.20.030 mitigation sequencing as required under criterion 3. 4 This is based on the assumption that the maintenance vehicle access corridor around the SFR would be 10 feet wide, and the corridor for the OSS-related tanks and mechanical system would be 16 feet wide as required by the OSS system engineer. Page 4 of 8 TABLE 1 – COMPARISON BETWEEN THE APPLICANT’S PROPOSED SITE DEVELOPMENT AND NOCA-RELATED ALTERNATIVE Comparison Criteria Applicant’s Proposed Site Development NoCA-Related Alternative Proposed layout • OSS tanks and mechanical system located along south parcel boundary, and installed near existing grade. • SFR located between OSS tanks with mechanical system and wetland mitigation area with SFR cantilevered over the slope using pin piles or piers for foundation support within the wetland buffer and mitigation area. • SFR located along south parcel boundary • OSS tanks and mechanical system located between SFR and wetland mitigation area. • Both the SFR and OSS tanks and mechanical system would require significant fill soil and possible retaining walls for foundation support, which would significantly impact the wetland buffer, mitigation area, and possibly the wetland. Amount of fill in wetland buffer, building setback & mitigation area5 Negligible if any Approximately 700 cubic yards (not including swell/shrinkage of the soil from loose in truck to compacted condition) Encroachment upon wetland mitigation area6 None Approximately 30% Encroachment upon wetland buffer7 Approximately 20%, but the cantilevered above the ground surface. Approximately 50% with possible impact to the wetland Compliance with RUE review criteria Would comply with RUE criteria 3 and 4 due to minimizing the impact on critical areas in accordance with mitigation sequencing (BIMC 16.20.030), and the proposed impact to the critical area would be the minimum necessary to allow reasonable use of the property (BIMC 16.20.080). Would not comply with RUE criteria 3 and 4 as intended due to not minimizing the impact on critical areas in accordance with mitigation sequencing (BIMC 16.20.030), and the proposed impact to the critical area would not be the minimum necessary to allow reasonable use of the property (BIMC 16.20.080). 5 Assuming all fill placement and no retaining walls. The slope of the fill soil as shown is likely at the steepest practicable angle (2H: 1V), and would likely be less steep, depending on geotechnical engineering recommendations. Even if retaining walls were utilized, ground disturbing construction and fill soil placement would be necessary within wetland buffer, building setback and mitigation area. 6 Same as footnote 4. 7 Same as footnote 4.

I am writing to express my concern with the proposed home building at the adjacent property to the North PLN 51139. First the fence that was in place for many many years was found to be significantly located into this adjacent property, so when Mercury Michael moved and placed a temporary fence we realized just how close this proposed home would be to our present structure. I did not want to argue this issue of correct property line but it is a large intrusion to our present space. The proposed location of the home would be very close to the bedroom windows of our home at 15520. If the new home is allowed then I would strongly suggest the septic be able to be on the South side or closer to our bedroom window to allow some more room between the two structures. I also have some issues with building in what at one time was a protected wetland. The slope of the property and the potential drainage into a seasonal pond and the shared Port Madison Water Company property or to the Puget Sound in the other direction, does not seem like the best ecological choice to me. Thank you very much for your consideration. Please contact me with any comments or questions. Andrew Fiscus Cell 206‐949‐9652 1 Page 1 of 2 Department of Public Works - Engineering Memorandum Date: March 19, 2019 To: Annie Hillier, Planner, Planning and Comm. Development From: Peter Corelis, P.E., Development Engineer Subject: PLN51139 RUE – Euclid House SFR Project Description: The proposal seeks a reasonable use exception to construct a single-family residence within a wetland buffer on lot 24 of the Plat of Port Madison. The subject parcel is identified by tax ID no. 4167-000-024- 0003 and is located east of Euclid Avenue NE between NE Endicott Road and NE Lafayette Road in the City of Bainbridge Island. Recommendation For Approval: I have completed a review of the above-referenced project materials received by the City on August 16, 2018. The reasonable use exception is recommended for APPROVAL based on the following findings pursuant to Bainbridge Island Municipal Code (BIMC) 16.20.080 and subject to the conditions. 1. The proposal is consistent with applicable regulations and standards as it pertains to surface stormwater drainage per BIMC 15.20 and 15.21; 2. The proposal protects the critical area functions and values consistent with the best available science as it pertains to the incorporation of low impact development (LID) for the purpose of handling of stormwater, retaining vegetation, and mimicking natural hydrology to the maximum extent feasible; 3. The site plan conforms to the City of Bainbridge Island Design and Construction Standards and Specifications, “the Standards”, where applicable; Recommended Conditions of Approval: 1. The project shall utilize minimal excavation foundation systems for portions of the structure within the wetland buffer. The minimal excavation foundation system proposed shall conform to the definition as cited in the City’s adopted LID manual, published as the 2012 Low Impact Development Guidance Manual For Puget Sound, and shall contain a combination of driven piles and connecting Page 2 of 2 components at, or above grade and allow the foundation system to engage deeper load-bearing soils without having a to dig out and disrupt upper soil layers. 2. Surface stormwater from the proposed structure and from the adjacent property to the south shall discharge and disperse at a location and in a manner consistent with BMP T5.10B – Downspout Dispersion Systems. A dispersion trench is required where less than 50 feet of vegetative flow path is provided. Trenches shall be placed as far upland from the wetland as feasible, but no closer than 10 feet downgradient from the reserve on-site septic field. Individual splash blocks may be utilized where the vegetative flow path is at least 50 feet downgradient of the discharge locations.

I would like to add my husband’s and my input concerning this project. I have read over many of the requirements that the developer needs to complete in order to obtain a reasonable use exception. The land has been classified as a category 4 wetland area, and in one of the documents it reads that “The land use impact is high.” And in the project narrative, it is written: “After applying the wetland buffers, only a small portion of the parcel is available for construction of the SFR (Single Family Residence). Therefore, in the absence of the RUE, the proposed site development would not be feasible.” Based on just these 2 comments excerpted from the paperwork I am trying to understand how the development of a house can proceed once these basic truths have been noted. The land has been labeled unfeasible. If you were to visit the site in real life and see the lot, it is basically a wetland ditch. There is a steep bank on the right hand side of the property, which directly abuts the property where we are living. This must be the buildable space as it’s been outlined in the paperwork the developers have submitted. The impact this will have on anyone living on our property would be high. Again, in the project narrative, this comment is included: “To minimize adverse impact to the wetland, the SFR (Single Family Residence) is proposed to be constructed in the southwestern most corner of the parcel, immediately north of the adjoining parcel with a SFR.” Based on the site map, the structure would be built between 5 and 15’ from the property line. Our buildings are currently also located very close to the property line. So although the lot next to us is large, because it is basically a slanted ditch, the house would need to be situated as close as possible to our house. This would affect the light coming into our yard and house, and I assume will affect the vegetation that is currently there. There are mature trees on the property which I’m thinking might have to be removed to build, which could make the remaining slope susceptible to erosion or slides. This would additionally affect our quality of life as our current house is situated in a quiet little corner of Port Madison, where there is privacy and a large amount of surrounding nature. We are new to the Port Madison neighborhood, and in walking around the streets, this does not seem the type of neighborhood where houses are crammed in one next to the other. Houses are situated on generous pieces of land, and this feels like a project with little regard for the existing feel of the neighborhood. Directly across the street from our house is one of the other wetlands that is mentioned in the report, where ducks roam and peeper frogs and other animals live. It’s a very pleasant spot. Building on the site adjacent would affect the neighborhood and our quality of life in a negative way. Having reviewed much of the related documentation on the Hearing Examiner’s page of your website, I do understand that the developer is within legal limits on this project. With all the new development going on all over the island, some of it tastefully done, some of it not, I wonder if moral rights could one day be considered in how the city approves or rejects proposals like this. I would like to request a review of if and how this development relates to the comprehensive plan of the island. In my opinion it seems to be in opposition to the goals of this plan. Thank you.
