SUMMARY The applicant requests approval of a conditional use permit to build an 8310-square foot church on a roughly 4-acre, relatively long and narrow parcel. Preliminary plans and elevations show the proposed building complies with applicable dimensional standards. The applicant will build two parking areas for the church, which together contain the number of parking spaces required by the applicable standards. A wetland crosses the site. There is not enough area north of the wetland for the church and all parking needed for it. The applicant proposes one parking area south of the wetland, at the end of a driveway that extends 400 feet from the church. The City Code requires parking to be within 200 feet of the building it serves. The applicant requests a variance to the parking location standard. The driveway between parking areas and other grading will affect roughly 3500 square feet of the wetland buffer. The applicant requests approval of a sensitive lands review to do so, and proposes to create more than 5300 square feet of wetlands on the site as mitigation. The applicant proposes to provide emergency access from Steve Street to the driveway between the two parking areas. Steve Street terminates at the east edge of the south half of the site. A crash gate or similar obstacle approved by the fire district will prevent access to the site from Steve Street generally. Other access to the site will be onto Spruce Street. Hearings Officer Larry Epstein received public testimony and evidence at a duly noticed public hearing in this matter on November 28, 1994. City staff recommended conditional approval of the applications. The applicant accepted the staff report and recommended conditions without correction or objection. Five area residents testified orally and several more testified in writing with concerns and objections. Most concerns involved traffic on Steve Street and 83rd Avenue, security from trespass and protection of the wetland. For the reasons listed herein, the hearings officer concludes each of the applications complies with the applicable approval criteria, subject to the conditions of approval recommended by City staff as modified and added to herein.

The hearings officer incorporates by reference the findings regarding the site and vicinity in Section III of the City of Tigard Staff Report dated November 18, 1994. 2. The tree survey submitted with the application does not reflect all of the trees in the north half of the site, based on the unrebutted public testimony at the hearing and the aerial photograph of the site in the record. III. APPLICABLE APPROVAL STANDARDS, 1. The hearings officer incorporates by reference the approval standards cited in Section III of the City of Tigard Staff Report dated November 18, 1994. 2. It was argued during the hearing that the Metzger Community Plan applies to the application, because it applied before the site was annexed from unincorporated Washington County, and residents were told it would continue to apply after annexation. The hearings officer finds the Metzger Community Plan is not an applicable standard in this case, because it is not a standard set out in the City's Comprehensive Plan or Development Code (ORS 227.173(1)), and it is not relevant based on an intergovernmental agreement or other law. IV. HEARING AND RECORD 1. Hearings Officer Larry Epstein received testimony at the duly noticed public hearing about this application on November 28, 1994. A record of that testimony is included herein as Exhibit A (Parties of Record), Exhibit B (Taped Proceedings), and Exhibit C (Written Testimony). Exhibit C includes the application and related evidence submitted by the applicant, letters from Bradley Tolliver, Mrs. Kristen Miller, S.L. Davidson and James Pease, and a petition dated August 8, 1994. The hearings officer also incorporates by reference the agency comments in Section IV of the City of Tigard Staff Report dated November 18, 1994. These exhibits are filed at Tigard City Hall. 2. City planner Will D'Andrea testified for the City. He summarized the staff report and recommendation. He highlighted conditions of approval requiring the applicant to obtain Division of State Lands permits for fill and excavation of wetlands, to relocate the building to comply with setbacks, to provide more detailed landscape and tree plans, and limits on access to Steve Street. 3. Leslie Ann Hauer testified for the applicant. She accepted the staff report and recommendation without objection. She summarized the process leading to the application. She responded to concerns about traffic on Steve Street by noting that street provides only emergency access. She responded to concerns about impacts on the wetland by noting the steps the applicant took to minimize those impacts. 4. W. Steven Royce, Don Graham, Bill Ford, Pat Fogg and Donna Zinter testified with objections, questions and concerns. The greatest concern was with the potential for traffic on Steve Street and 83rd Avenue. If access is to be allowed at all, it should be restricted by a locked gate to emergency situations only. Another concern was with the need for visual and physical security on the site. A six-foot high fence is proposed around only portions of the site, and six-foot tall trees (at planting) and fences will not protect visual privacy on the second floors of homes adjoining the site. Concerns also were raised about protecting wildlife habitat and about the inaccuracies on the tree survey. Page 2 Hearings Officer Final Order CUP 94-00071VAR 94-00091SLR 94-0005 (Japanese lnt'1 Baptist Church) 0 0 5. Mr. Royce also requested the hearings examiner continue the hearing to another night so the applicant could address the concerns he raised. The hearings officer denied that request, because evidence in support of the application was not introduced within 20 days of the hearing, and because the issues raised by Mr. Royce are addressed in the findings or are or can be addressed in conditions of approval to the extent those concerns are relevant to applicable standards. The hearings officer offered to hold open the record for seven days, but no party requested it, so the record closed when the hearing closed. V. EVALUATION OF REQUEST 1. The hearings officer incorporates by reference the findings about compliance with the Community Development Code and Comprehensive Plan in Section V of the City of Tigard Staff Report dated November 18, 1994. 2. The principal issue raised by the testimony is whether the conditional use complies with the standards in CDC section 18.130.040. a. CDC section 18.130.040 requires the characteristics of the site to be suitable for the proposed use. It was argued that the site is unsuitable, because of the wetlands and trees on the site and because of the proximity and design of adjoining homes and lack of detail on landscape plans. b. The hearings officer finds that the site is suitable, because it can be developed for the proposed use in a manner that complies with applicable development and design standards (save one), including standards designed to protect the wetland and the privacy and security of adjoining land uses, based on the preliminary plan. The site is larger than necessary to meet the needs of the proposed use; the south end of the site will remain undeveloped. The applicant can provide the setbacks, fencing and landscape buffers required by the CDC with certain modifications to the preliminary plan. The applicant can provide required landscape materials, and conditions of approval are recommended to assure they are provided. c. The characteristics of the site are such that the driveway will approach and adjoin the east property line for a distance. The drive cannot be moved farther west to provide more room for landscaping without further reducing the wetland area. City regulations do not expressly prohibit the drive adjoining the property line (see, e.g., CDC section 18.106.050.17, G & K and CDC Chapter 18.108). In contrast, further reduction of the wetland violates CDC section 18.84.040.D.2, because it is not necessary to do so to accommodate the proposed use. Therefore, the hearings officer finds that the site is suitable, notwithstanding the proximity of the drive to the adjoining residential land uses, provided: (1) The applicant should install a minimum 6-foot high sight- obscuring fence or wall along the east edge of the site from Spruce Street to the south edge of the site or to and along the south edge of the southern-most parking area to protect the privacy of adjoining residents. Where there is less than a 10-foot buffer between a drive or parking area and a property line, the fence should be 8 feet high and should be built of wood or masonry materials. This is permitted by CDC 18.100.090.A, subject to a building permit for the fence. (2) The applicant should plant conifer trees at least five feet high at planting and at a spacing designed to achieve a continuous and relatively opaque barrier between property lines and parking areas or drives where there is sufficient room for that purpose, in addition to other required landscaping, where the applicant does not preserve Page 3 Hearings Officer Final Order CUP 94-00071VAR 94-00091SLR 94-0005 (Japanese Intl Baptist Church) 0 9 existing trees providing the same effect in those areas; and (3) The applicant should retain existing deciduous trees larger than 10 feet in height and conifer trees larger than 5 feet in height to the maximum possible extent in landscape and buffer areas. This is consistent with CDC section 18.150.030.A.2 and 5, and can be administered as part of the City tree removal regulations; and (4) The impact of traffic on the site on adjoining residential uses can be minimized by restricting vehicular access to the site or to the area south of the main parking lot except when needed for events at the church. See paragraph (5) below. (5) Parking and access drives on the site are required to be lighted, and that lighting is required to be directed away from adjoining residences. See CDC sections 18.106.106.020.P and 18.106.050.N. Recommended condition of approval 10.b requires the applicant to submit a lighting plan for review and approval. This is the primary means by which security and safety is provided at the site. CDC section 18.120.108.A.10. (6) However, the south end of the site is not readily visible from the church due to distance and intervening vegetation. Given the lack of that observation, the hearings officer finds that additional measures should be taken to address the security of the site and adjoining land uses. In this case, one or more of the following measures could be used. The applicant should choose which measure or measures to use, and should include them on the final site plan submitted pursuant to condition of approval 10. (a) The applicant could restrict vehicular access to the site generally by installing a gate or other obstacle across the entry to the site and at least twenty feet from Spruce Street. This gate should be locked unless the church is in use; and/or (b) The applicant could restrict vehicular access south of the main parking area by installing a gate or other obstacle in the driveway. This gate should be locked unless the area south of the main parking lot is needed for parking for events at the church; and/or (c) The applicant could install a minimum 6-foot high fence around the southern-most parking area where not otherwise required to comply. d. CDC section 18.130.040 also requires public facilities to have adequate capacity to serve the proposal. Public streets are a form of public facility. There was testimony against allowing use of Steve Street and 83rd Avenue for access to the site, even for accessory purposes. However, the examiner finds that the physical characteristics of the site, i.e., its relatively long narrow configuration in which parking is distant from the main entry, warrant such an emergency access point. SW Steve Street and 83rd Avenue are sufficiently improved to accommodate emergency traffic, based on the written testimony by the City. Vl. CONCLUSION AND DECISIQNI 1. The hearings officer concludes that the proposed conditional use permit, variance and sensitive lands review does or will comply with the applicable criteria and standards of the Community Development Code, provided development that occurs after this decision complies with applicable local, state, and federal laws and with conditions of approval warranted to ensure such compliance occurs.

The City of Tigard Maintenance Services Department, Tualatin Valley Water District, Portland General Electric have reviewed the proposal and have offered no comments or objections. V. EVALUATION OF REQUEST 1. Compliance with Community Development Code. Section 18.52. The applicant is proposing to build a church facility. A church is classified in code section 18.42 (Use Classifications) as Religious Assembly. Code Section 18.52.040 allows Religious Assembly as a Conditional use. The impervious surface/landscape requirement is satisfied as the applicant is proposing to devote approximately 57,930 square feet (33%) as impervious surface. The proposed building height, as defined by code, is approximately 24 feet. The top of the building will in effect be at a height of approximately 33 feet. In either case, the proposed building meets the applicable height requirement. While the R-7 zone ordinarily limits building heights to 35 feet, the provisions of section 18.98 apply to this proposal. This section states that projections such as spires not used for human occupancy, are not subject to the building height limitations of this title. The proposed spire is therefore not restricted to a maximum height of 35 feet. Section 18.130.040: This proposal is consistent with the applicable approval standards. The site will provide adequate area for the proposed church. The irregular lot shape and presence of wetlands may not make for the best site for this proposal, however site characteristics are suitable to accommodate the proposed church. Adequate public facilities are present and currently serve the site or shall be provided by conditions of approval. Compliance with the applicable zoning district requirements, Conditional Use Review and Comprehensive Plan Policies can be satisfied by this proposal as demonstrated by the analysis presented within this report and review process. Section 18.130.150(C)(10) is satisfied. The subject site is approximately 4 acres, well in excess of the minimum 20,000 square foot lot area. As indicated on the site plan, the church facility setbacks are in compliance with the R-7 zone standards. The HEARINGS OFFICER - CUP 94-0007NAR 94-0009/SLR 94-0005 Japanese Int'1 Page 12 0 0 conditional use criteria for a church also requires increased setbacks for buildings over 45 feet in height. This criteria is not applicable as the building is not greater than 45 feet in height. Section 18.120.180.A.2. is satisfied as the building and improvements are proposed to be located so as to preserve the existing wetland, drainageway and trees. The applicant has requested a variance to the parking standard to allow preservation of the wetland and has requested for the removal of 4 trees. Section 18.120.180.A.4 is satisfied as the plan shows that the building meets the required side yard setback standard of 20 feet. Section 18.100.130 (Buffer Matrix) does not have requirements for buffers related to church facilities. Staff recommends that in order to further buffer the properties on the west property line the applicant shall relocate the church building 10 feet to the east, creating a 30 foot setback. It is also recommended that the applicant provide either a six foot fence or plant material in accordance with the screening standards as found in section 18.100.080 in an effort to provide a further noise barrier between the church and existing residences located to the west. A fence shall also be provided to screen the access drive south of SW Steve Street. Section 18.120.180.A.5 is satisfied as the plan shows a 20 foot buffer along the west property line and a recommendation has been made that the plan be revised to increase that buffer to 30 feet. To further protect adjoining private spaces the entrance to the building is located on the east side of the building, as is the required parking. The buffer along the east property line is recommended to be reduced to a 10 foot buffer. This width is in accordance with the buffer matrix requirements and is expected to have less of an impact on the adjoining property than would the building itself. An exterior lighting plan shall be submitted which shows that adjoining properties will not be impacted by parking lot lighting or building lighting. Section 18.120.180.A.10 shall be satisfied as the applicant shall be required to provide an exterior lighting plan for review and approval. Section 18.84.040.D is satisfied. The wetland is not designated as significant on the Comprehensive Floodplain and Wetland Map. The wetlands report stated that the wetland were found to have low value for active recreation, nutrient retention/removal, on- and offsite runoff flood storage/ desynchronization, sediment trapping and food chain support and also that the site had low to moderate value for wildlife habitat. The site disturbance will be the minimum necessary to accomodate the proposed HEARINGS OFFICER - CUP 94-0007NAR 94-0009/SLR 94-0005 Japanese Int' 1 Page 13 0 0 improvements. The proposal would effect approximately 3,536 square feet of the 48,390 total square feet of wetland area (approximately 7 percent) and will be mitigated with the creation of approximately 5,358 square feet. Drainageway changes will not adversely impact wetland characteristics. The existing culvert will be extended approximately 25 feet and will continue to drain into the wetland area, which will remain undisturbed. Erosion control measures and replanting related to proposed improvements shall be satisfied through the applicable Division of State Lands permits. Other sensitive lands sections are not applicable to this site. The applicant has been conditioned to obtain a tree removal permit for all trees greater than 6" in diameter. The applicable Comprehensive Plan policies have been satisfied and are addressed below. Section 18.100.015. This requirement has been satisfied as the applicant has submitted a plan indicating the type and location of trees and shrubs, and as addressed in the applicable sections below. Section 18.100.030. The preliminary landscape plan does not address the provision of street trees, therefore a revised landscape plan shall be submitted which complies with this section. Section 18.100.110W. A revised landscape plan shall be submitted which provides parking lot trees, in landscaped islands, based on one per seven spaces in order to provide the required canopy effect. The revised plan shall also indicate the type and form of landscaping which screens the parking lot. Section 18.100.130. All three parking areas abut residential uses. A 10 foot buffer, with screening, shall be required between all three parking areas and the adjoining property. A revised site plan shall be submitted which provides for these required buffers. The 48 space north parking lot buffer area contains approximately 2,750 square feet. Therefore, this buffer shall contain 25 five gallon or 50 one gallon shrubs in addition to the one row of trees. The five space parking area shall provide for a 10 foot buffer along the entire length of the adjacent north property line and for approximatley 95 feet along the east property. This buffer area is approximately 2,400 square feet. Therefore, this buffer shall contain 25 five gallon or 50 one gallon shrubs in addition to the one row of trees. A revised landscape plan shall be submitted indicating landcaping and screening within the buffer areas in accordance with this section. The applicant has proposed to locate an access drive within the required buffer area. The applicant is limited in locating the driveway due to the wetlands. The size of the parking area combined with the useage associated with a church facility HEARINGS OFFICER - CUP 94-0007NAR 94-0009/SLR 94-0005 Japanese Int'l Page 14 0 0 should not create a high volume or demand for this lot. Given the locational restrictions and expected demand, staff would recommend approving the drive within the buffer area. Section 18.102.020. This criteria shall be satisfied as the revised landscape plan shall be reviewed for compliance with vision clearance criteria. Section 18.106.030(B)(8). The santuary has been proposed with a seating capacity of 240 seats. Requiring 1 space for every 3 seats results in a total parking requirement of 80 spaces. The site plan shows the provision of 80 parking spaces. The site plan also indicates the provision of 4 handicapped accessable parking spaces, satisfying this requirement. Section 18.106.020(H). The applicant is providing 48 of the required 80 parking spaces within 200 feet. The applicant is requesting for a variance to allow 32 spaces to be located beyond the required 200 feet, and is address in section 18.134 below. Section 18.106.050(B). A revised plan shall be submitted which provides for parking area dimensions in accordance with the provisions of this section. Section 18.106.050(N). The preliminary site plan does not show the location of lighting fixtures. A lighting plan shall be submitted which provides lighting in accordance with this section. Section 18.106.020(P) . Based on the ratio of 1 bicycle rack per 15 vehicular spaces this site requires 5 bicycce parking spaces. The site plan does not show any bike racks. A revised site plan shall be submitted which shows the provision of 5 bicycle parking spaces, thereby satisfying this criteria. The applicant states that a church is a use which typically draws persons dressed in clothing not suitable for bicycle riding and as such believes that very few, if any, church members will arrive by bicycle. If bicycles are used by members provisions can be made adjacent the the building. While staff understands that members arriving for service may prefer to drive, service is not the only activity which draws people to a church. There are many church activities which would allow for dress that is bicycle compatible. The applicant states that the site was chosen within a residential area where it could best be able to serve its community. Staff believes that providing convenient bicycle accessibility could make the church more attractive a destination for nearby residents. In addition, the Transportation Planning Rule encourages offering alternatives to driving the automobile and nearby residents would be given that alternative. HEARINGS OFFICER - CUP 94-0007NAR 94-0009/SLR 94-0005 Japanese Int'l Page 15 0 0 Section 18.108.080. The proposed plan shows a 20 foot wide driveway. A revised plan shall be submitted which provides a 24 foot paved accessway. Section 18.108.050(A). The preliminary plan shows the provision of a 4 foot sidwalk connecting the building to SW Spruce Street. To provide for a pedestrian connection to existing surrounding development the applicant shall provide a walkway connection from the proposed driveway to the sidewalk on SW Steve Street. Section 18.114.130(A). All signs shall conform to the provisions listed in this code section. All signs shall be approved through the Sign Permit process as administered by the Planning Division. Section 18.134.050. The applicant is requesting a variance to allow 32 of the required 80 parking spaces to be located more than 200 feet from the building. The special circumstances that exist are the shape of the subject property and the presence of wetlands. The wetland area and width of the lot prohibit the applicant from providing the parking within the required distance. The wetland divides the property in half such that the applicant is placing the remaining parking as close to the church as possible, without proposing to fill the wetland area. The proposed variance will in no way affect the conditional use status of this proposed church. All other applicable City standards will be maintained, as discussed in this report. Existing physical and natural systems would be adversely affected if it were not for this variance as the applicant would propose to fill wetland area. The applicant is proposing to preserve the wetland by incorporating it into the site plan, and can only accomplish this by the granting of the variance. The hardship related to this variance is not self-imposed and is the minimum variance which alleviates the hardship. The applicant is attempting to design the project around the existing wetland while locating the parking as close as possible within existing property boundary. Section 18.150. This requirement will be satisfied as a tree removal permit will be required for the removal of trees with trunk diameters of six inches or more in diameter. PUBLIC FACILITY CONCERNS: Sections 18.164.030 (Streets), 18.164.090 (Sanitary Sewer), and 18.164.100 (Storm Drains) shall be satisfied as specified below: 1. STREETS: HEARINGS OFFICER - CUP 94-0007NAR 94-00091SLR 94-0005 Japanese Int'1 Page 16 9 0 The applicant proposes access from SW Spruce Street, a local residential street, with emergency access only from the end of SW Steve Street. Although the project property was recently annexed to the City, SW Spruce Street is a County Road and the applicant shall obtain a County Facilities permit. SW Spruce Street right-of-way is 60 feet wide and is sufficient for the proposed use. The applicant should be required to improve the street along the frontage and over to the intersection with SW 85th Avenue, as shown on the proposed site plan, to City standards with concrete curb, sidewalk and asphalt concrete pavement, with the curb to be located 17 feet from centerline. In addition, the existing pavement in SW Spruce Street is of unknown origin and the improvements should include an additional 12 foot lane on the opposite side of the street and an asphalt concrete overlay of the existing pavement over to SW Hall Boulevard, to provide an adequate access to the church. With respect to SW Steve Street, the applicant does not propose to modify the existing street end although the street is 160 feet long. The applicant notes that the existing wetland at the end of SW Steve Street precludes the ability to extend the street. Instead, the site plan proposes to cross the wetland with a narrow driveway only, to connect the principal church parking lot with an additional parking lot at the rear of the site. The driveway would be located adjacent to the end of SW Steve Street, which would enable an emergency vehicle to access the site from the end of the existing street. Staff concurs with this proposal. In addition, the street end should be provided with sufficient signage to inform the general public that SW Steve Street is a "dead end", with no outlet. Overhead utilities are existing on the southerly side of SW Spruce Street. The overhead wires should be placed underground or the applicant should pay the fee in- lieu of undergrounding. Also, a street light should be installed at the easterly edge of the driveway to illuminate the intersection with SW 85th Avenue. 2. SANITARY SEWER: The site is served by the existing 8 inch public sanitary sewer that crosses the site in an existing easement. The sewer has sufficient capacity for the proposed development. There is also an existing sewer in SW Spruce Street. 3. STORM SEWER: HEARINGS OFFICER - CUP 94-0007NAR 94-0009/SLR 94-0005 Japanese Int'l Page 17 0 0 The site currently drains to the existing swale that crosses the site through the wetland described above. The applicant proposes an underground storm drain system to collect the stormwater from the proposed buildings and parking lots, that would drain to an on-site water quality facility, before being deposited into the swale. The Unified Sewerage Agency has established and the City has agreed to enforce (Resolution and Order No. 91-47) Surface Water Management Regulations requiring the construction of on-site water quality facilities or fees in-lieu of their construction. As noted, the proposed use of an on-site dry pond will provide the required water quality facility. The facility should be designed to comply with the minimum USA standards and shall be maintained by the applicant. 2. Compliance with Comprehensive Plan Policies: This proposed Conditional Use complies with all applicable Comprehensive Plan Policies as follows: 1. Citizen Involvement. Policy 2. 1.1 is satisfied as the applicant was required to hold a neighborhood meeting with nearby property owners, notice of the application and public hearing on this item was provided to the Citizen Involvement Team East Representative, to owners of property in the vicinity of the site and in a newspaper of general circulation. The site has also been posted with a sign which states that a land use development application is pending for this property. 2. Wetlands: Policy 3. 1.1 is satisfied as the applicant shall be required to comply with Division of State Lands Removal/Fill Permit criteria. 3. Water Oualitv.

CLIENT: Japanese International Baptist Church site, c/o Buck Lane 520 N.W. 80th Street, Vancouver, WA 98665 AREA: Approx. 4 acres (including homestead on Tax lot 790). ELEVATION: 180 to 220 feet Mean Sea Level (from Beaverton, Ore& quadrangle). TOPOGRAPHY: Gently sloping, alluvial terrace with intermittent creek, portions of site just north of creek filled between 1979 and 1985. WATERWAY: Unnamed tributary to Ash Creek, then Fanno Creek and Tualatin River. WETLAND TYPE: Palustrine, Emergent, Saturated (PEMC) and Palustrine, Scrub/Shrub, Saturated (PSSC). PROPOSED USE: Congregational church. PRESENT USE : Currently vacant (filled portions are abandoned). PAST USE: Former junkyard and residence.

Field study conducted on February 16 (Tax lots 701 and 709), April 16 (Tax lot 4400 hydrology and soils), and June 18, 1992 (Tax lot 4400 vegetation). VEGETATION: The site has the following major plant communities: emergent meadow, grassland on fill material, and scrub/shrub bottomland. Only the emergent meadow and scrub/shrub bottomland areas have more than 50 percent OBL, FACW, and/or FAC dominance. The transition from these communities to the upland grasslands community is generally an abrupt one, and is marked by an absence of ash trees, red osier dogwood, sedges, rushes, and other common hydrophytic (orbs. SOIL: The soils present in the study area include Cove silty clay loam, Aloha silt loam, and Urban fill. Only the Cove soil type, found at the lowest elevations on the south part of the site, is considered hydric. An aquic moisture regime, low chroma matrix, and distinct mottling are all apparent in this soil type. Post Office Box 3558 Jibc WL c 920619.rev Page I Portland.

The portion of the site north of the creek has been significantly altered, including selective clearing, creek channelization, filling, and nearby land development. The areas where wetland hydrology is present include the remaining emergent grassland and scrub/shrub bottomland in the south parts of the site, and a small remnant segment of emergent grassland between Tax lots 701 and 4400. The wetland hydrology indicators noted in these areas were soil saturation in the major portion of the root zone and to the surface, pondinQ in the lowest elevations, wetland drainage pattern, and water- stained leaves. DETERMINATION: The jurisdictional wetlands within the study area identified under both the 1987 Corns of Engineers Wetlands Delineation Manual and the 1989 Federal InteraQencv Wetlands Manual for Identifvins and De ' na Jurisdictional Wetlands include the remaining emergent grassland along the west boundary of the site, the scrub/shrub bottomland in the south parts of the site, and the small remnant segment of emergent grassland between Tax lots 701 and 4400. The area of wetland at the site is 1.1 acres, which was calculated from field measurements of the wetland flagging.

The study area is located at 8500 S.W. Spruce Street (north edge of property) and it is bounded by residential properties to the east, west and south. Access to the property is easiest from the west terminus of Steve Street which intersects the east property line. About half of the surrounding lands have already been partially filled or developed for residential use (Figure 1). Site Use Present and Past As a rural homestead and former junkyard, the condition of the site reflects a history of disturbances, including selective clearing, upgradient creek channelization (culvert), filling, and dumping. At present, the site includes an older residential home, an detached multi-bay garage, and areas of older fill now overgrown with grasses and blackberries. The Japanese International Baptist Church acquired the property from the previous owner who used the land as a rural junkyard. That owner filled part of the south portion of Tax lot 701 just north of the intermittent creek before 1975, and the north portion of Tax lot 4400 between 1979 and 1985. The 1979 aerial photograph included in Appendix A shows the south part of Tax lot 701 already filled (a 1975 aerial shows the same, although it was not included with this report). The 1985 aerial shows the north portion of Tax lot 4400 filled, but to a lesser degree than on Tax lot 701. In fact, only 12 to 18 inches of fill was added to this area and the Oregon ash trees were left (hence, the fill was placed between the trees). Five years later, the 1990 aerial shows that all of the area south of the intermittent creek has remained undisturbed, while the areas to the north have become re-vegetated with grasses and blackberries (it appears the areas north of the intermittent creek have been effectively filled). The fill material is composed of mixed soil materials and varies in depth from 1 to more than 3 feet thick. In places, the fill also includes rocks and construction/road debris. Over the past several years since the Church has owned the property, the congregation has removed nearly Post Office Box 3558 Jibc WL delin. 920619.rev PAGE 1 Portland, ore. 97208 (503) 221-2811 F70LES ASSOCIATES REVISED JAPANESE INT'L BAPTIST CHURCH WETLAND REPORT W4TYX k ATTIANTn SCR%MSTS all of the junk: left behind by the previous owner. The Church has never placed any additional fill on any portion of the site. RegulaLMv Back-,round Wetlands, whether they are marshes, bogs, wet meadows or bottomlands, can provide essential habitats for wildlife, provide flood protection through absorption of storm water, improve water quality by retention of sediments and add scenic diversity and aesthetic value to the landscape. To curb loss of wetland acreage, federal and state legislation exists to preserve wetland values and functions. The Clean Water Act (33 U.S.C. 1344) was enacted by the U.S. Congress to maintain and restore water quality, biological integrity and chemical balance of all Water of the United States. The Act empowered the U.S. Army Corps of Engineers (CE) with a jurisdiction over filling of wetlands and authorized the U.S. Environmental Protection Agency (EPA) to oversee the CE fill permitting process. Through the Oregon Removal/Fill law, the Division of State Lands (DSL) also has jurisdiction over filling and dredging of wetlands and issues a concurrent permit with the CE. In January 1987, the C ps of Engineers Wetlands Delineation Manua( was issued to provide technical guidelines for identifying wetlands, and provide supporting information and methods for applying the technical guidelines. This manual was later revised and adopted in January 1989 by the CE, EPA, U.S. Fish and Wildlife -Service (USFWS), and Soil Conservation Service (SCS) as the Federal Manual for Identifvina and Delineating Jgrisdictional Wetlands. For administrative and political reasons, the federal regulatory agencies currently relies on the 1987 CE Manual as their official delineation procedure, while the DSL uses the 1989 Interagency Manual for delineations. Definitions Wetlands The Clean Water Act and both wetland Manuals define wetlands as: "Those areas that are inundated or saturated by surface or ground water at a frequency and duration Post Office Box 3558 Jibc WL delin. 920619.rev PAGE 2 Portland, Ore. 9:208 (503) 224-2811 • REVISED JAPANESE INT'L BAPTIST CHURCH WETLAND REPORT PIOUS ASSOCIATES s~ .mxvr. sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." (33 CFR 323). Nonwetlands The 1987 CE Manual for clarification defines nonwetlands as uplands and lowlands that are rarely to frequently inundated, have saturated soil conditions for a very short time in the growing season and support nonhydrophytic vegetation adapted to aerobic soil conditions. Appendix B includes a more detailed definition and lists the diagnostic conditions that typify a nonwetland. WETLAND CLASSIFICATION In 1979, the U.S. Fish and Wildlife Service (USFWS, Dept. of Interior, Cowardin, et al.) developed a classification system for use in identifying, categorizing, and mapping deep- water habitats and special aquatic sites, including wetlands. The classification system beeins with five broad classes Marine, Estuarine, Riverine, Lacustrine, Palustrine that further break down into many subclasses defined by water regime, substrate condition, vegetation cover, and human-influenced factors. The National Wetlands Inventory (NWI) maps identify these natural resources as overlays to U.S.G.S. quadrangle maps The accuracy of the NWI maps is limited, since the mapping utilized high-resolution aerial photographs and topographic data as the primary basis for wetland identification. Consequently, the NWI rarely identify agricultural wetlands, disturbed wetlands, very small seasonal wetlands and urbanized (remnant) wetlands, even though these are true jurisdictional wetlands. Generally, onsite field study is necessary to confirm the presence or absence of NWI-identified wetlands, in addition to defining the jurisdictional boundary.

Hydrophytic species, due to morphological, physiological, and/or reproductive adaptation(s), have the ability to grow, effectively compete, reproduce, and/or persist in anaerobic soil conditions. ,Soil: Soils are present and have been classified as hydric, or they possess characteristics that are associated with reducing soil conditions. BvdrolDay: The area is inundated either permanently or periodically at mean water depth <_6.6 feet, or the soil is saturated to the surface at some time during the growing season of the prevalent vegetation. Under normal circumstances, both delineation manuals require that positive indicators of wetland hydrology, hydric soil and hydrophytic vegetation be present for an area to qualify as wetland. Many natural situations exist where one or two of the evaluation parameters have positive indicators, but remaining indicator(s) is misleading. For example, low chroma matrix colors may reflect the soil mineralogy instead of anaerobic conditions and many wetland plant species can grow in non-wetland environments. Furthermore, hydric soil indicators or hydrophytic plant dominance may persist long after the wetland hydrology has changed due to local/regional flood control, historic/pre-jurisdictional draining or surrounding development. For these reasons, the manuals require positive indicators of all three parameters to ensure consistent and technically accurate wetland delineations. There are circumstances when one or more of the mandatory wetland criteria are not present as a result of natural events or human activities. Natural events, like river course changes, avalanches, or beaver dams, may create new wetlands that lack a predominance of Post Office Boa 3558 Jibc WL delin. 920619.rev PAGE 4 Partland, Ore. 97208 (503) 224.2811 • REVISED JAPANESE INT'L BAPTIST CHURCH WETLAND REPORT "SCOLES ASSOCIATES StIIL %VAIU a ri'LTI.V.77h s0t_."TiM hydrophytic vegetation or hydric soil characteristics. Human activities, such as ditching (or tile draining), filling, diversion construction (berms or levees), irrigation, grading or clearing, may obscure or disguise some of the mandatory wetland criteria. In these or similar situations, both manuals have provisions to define the wetland based on fewer parameters. Specifically, the 1987 CE Manual considers unauthorized filled or drained wetlands, newly- formed wetlands (by natural event) and human-induced wetlands as atypical wetlands, which by definition lack one or more of the mandatory criteria. The 1989 Interagency Manual renamed this category to disturbed wetlands and expanded it to include wet agricultural lands, wet pastures, wet lowlands, and recently-cleared wetlands. Both manuals also identify the following problem area wetlands which might lack hydrophytic plant dominance during the later part of the growing season, and/or have marginal or no hydric soil characteristics: Wetlands on glacial till, variable seasonal wetlands, prairie potholes, vegetated flats, interdunal swale wetlands, vegetated river bars and adjacent flats, caprock limestone wetlands, newly created wetlands, entisols, red parent material soils, spodosols, mollisols and wetlands dominated by facultative upland species (the later eight categories apply to the 1989 interagency Manual only). Atypical, disturbed and problem area wetlands generally need additional site study to confirm the wetland boundary. HYDROPHYTIC VEGETATION Definitions The 1987 CE Manual defines hydrophytic vegetation "as the sum- total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present." The 1989 interagency Manual defines hydrophytic vegetation as "macrophytic plant life growing in water, soil or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content." The presence of a few individual hydrophytic plants amidst an upland plant community is not evidence of hydrophytic vegetation or visa versa.

For both manuals, the hydrophytic vegetation criteria is met when the dominant species comprising the plant community are typically adapted to saturated soil conditions. The manuals specify an area has hydrophytic vegetation when more than 50 percent of the dominant species from all strata are designated on national or regional lists as obligate (OBL), facultative wetland (FACW) or facultative (FAQ. Table 1 describes the frequency in which each of these categories occur in wetlands. For Oregon and Washington, the National List of Plant S ecif+s That Occur in Wetlands: Northwest (Region 9) (Reed, 1988) compiled by the USFWS assigns one of these ratinss to indigenous and introduced plant species. If a particular plant species. has inconclusive data regarding its occurrence in wetlands, then it is designated as non-indicator (NI). Since the list does not focus on upland species (far too many to include), a not listed (NL) designation is used and is normally inferred to be an upland (UPL) species. - The 1989 Interagency Manual alternatively permits the use of a frequency analysis of species within a designated area to qualify as hydrophytic vegetation if the prevalence index value totals '3.0 or more, provided the hydric soil and wetland hydrology criteria are met. In addition to the plant dominance criteria described above, the 1987 CE Manual allows the following indicators to be used as positive indicators of hydrophytic vegetation: visual observation of plants species growing in areas of prolonged inundation and/or soil saturation, morphological plant adaptations, technical literature which document the presence of specific plant species in saturated soils for long periods, physiological adaptations, and reproductive adaptations.

Soils are composed of varied percentages of organic and mineral fractions sand, silt, clay and rock fragments. Both delineation manuals define hydric soil as one "that is saturated, flooded or ponded long enough during the growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic vegetation." The 1987 CE Manual defines the duration of saturation, flooding, or ponding as S and 12.5% of the growing season, while the 1989 Interagency Manual defines this as seven days or more in the crowing season.. Both manuals concur that the growing season begins when the soil temperature rises above 41 degrees F and ends when the soil temperature drops below this "biological zero". For the lower elevations of the Tualatin Valley, the growing season (on the average) be-ins March 1 and ends October 31. Soil Criteria and Indicator The National Technical Committee for Hydric Soils (NTCHS) in December 1986 developed the following hydric soil criteria: "1. All Histosols except Folists; or 2. Soils in Aquic suborders, Aquic subgroups, Albolls suborder, Salorthids great group, or Pell great groups of Vertisols that are: a. somewhat poorly drained and have water table less than 0.5 feet from the surface for a significant period (usually a week or more) during the growing season, or b. poorly drained or very poorly drained and have either: (1) water table at less than 1.0 feet from the surface for a significant period (usually a week or more) during the growing season if permeability is equal to or greater than 6.0 inches per hour in all layers within 20 inches, or Post Office Box 3558 Jibc WL delin. 920619.rev PAGE 7 Portland.

Soils that are ponded for long duration or very long duration during the growing season; or 4. Soils that are frequently flooded for long duration or very long duration during the growing season." This criteria encompasses both drained or undrained soils, so only those hydric soils which support hydrophytic vegetation and have positive wetland hydrology indicators are considered wetland soils. Drained hydric soil, that which no longer supports hydrophytic vegetation, can be characterized by the presence of dikes or levees, ditches or subsurface drains, flood control and upgradient diversions of runoff or ground water flow. Over time, soil profiles develop diagnostic horizons (layers) and color patterns that reflect environmental influences. Climate, organisms, parent material, topographic relief and time are considered the primary influences in soil formation. Physical and chemical weathering of the parent material varies from location to location, so different soil characteristics evolve within a short distance of each other. Under saturated or flooded conditions that become reduced (anaerobic) for part of the Growing season, soil profiles usually acquire unique characteristics that can be relied upon as positive indicators of hydric soil. Most organic soils (Histosols) are hydric, while mineral soils tend to develop one or more of the following characteristics when associated with a reducing environment: Histic epipedon (organic surface horizon), hydrogen sulfide odor and other sulfidic material, aquic moisture regime (oxygen-deficient soil saturation), reduced soil conditions, gleyed soil matrix color, low chroma matrix color with or without bright mottling, soil series on hydric soil lists, and segregated iron and manganese concretions. Hydric sandy soils may lack these characteristics, but may have a high organic matter content in the surface horizon, organic matter streaking in the subsoil, and illuviated organic and/or spodic horizons.

This definition includes all those areas where the surface and/or ground water has an overriding influence on the soils and vegetation by facilitating anaerobic conditions. The 1989 Interagency Manual defines wetland hydrology in a similar manner. Both manuals concur that hydrology is the driving force of wetland creation, and as an evaluation parameter it is often the least precise and most difficult to document due to seasonal changes in soil saturation, ponding, and flooding. CAteria Like soil formation, climate, topography, stratigraphy, soil permeability, plant cover, and land use all influence soil wetness. The duration of soil saturation and/or inundation varies due to seasonal fluctuations of the ground water, precipitation events and flooding, surface ditches and/or subsurface tilina. local and/or regional flood control, and adjacent land use. The hydrologic regime is frequently summarized as one of the classes shown on Table 2. Actual observation of wetland hydrology is sometimes difficult to document due to the timing of the field evaluation and seasonal nature of many wetlands. For the purposes of wetland delineations, the following indicators are regarded as evidence of sufficient hydrologic conditions: Visual observation of inundation and ground water saturation, watermarks, sediment deposition, drift lines, drainage patterns, stream gauge data, and historic records. The 1989 Interagency Manual also allows the use of hydric soil characteristics as a surrogate for the absence of other hydrology indicators.

Offsite inspections are commonly done for wetland inventories or when only an approximation is needed for a particular purpose. Onsite inspections are done when a precise wetland boundary is needed to assess potential impacts from new development, chance of land use or simply total the wetland acreage for a specific area. The standard routine level approach generally involves assembling existing information (maps, aerials, etc.) and an onsite inspection/study to conclude on the location of the wetland boundary. The comprehensive-level approach is infrequently needed, since it applies to very complex situations and requires extensive field research and data analysis to complete. More commonly, the Routine, Level 2 (1987 CE Manual) and intermediate-level (1989 Interagency Manual) approaches are utilized since they incorporate more field study than the standard routine level methods, and they usually determine the wetland boundary using site-specific data. This wetland determination was made using the techniques described in both manuals to meet CE and DSL requirements. At the request of the client, site conditions on Tax lots 701 and 790 were studied on February 16, 1992 by the consultant team. For additional planning purposes, Tax lot 4400 was later studied on April 16 to characterize the hydrology and soils, and on June 18, 1992 to identify the vegetation. For regulatory purposes, these lots were determined to have normal circumstances, since the site was hydrologically altered more than 5 years ago (previously discussed). The site has remained undisturbed, except for hand-removal of junk auto parts left behind by the previous owner. The field observations were recorded on data sheets (Appendix C), and the wetland determinations are summarized in the following report text. Five transects were established to document existing site conditions and locate the wetland boundary. Transect 1 was located parallel to the west property line, which includes sample plots in native soil and fill material. Transect 2 was set on the east side of the site and through a remnant segment of land that did not get filled (unlike surrounding land) to document similar native and fill conditions there. Transects 3 and 4 were established on the Post Office Box 3558 Jibc WL delin. 920619.rev PAGE 11 Portland.

Finally, Transect 5 was located on the south side of the intermittent creek to describe the natural wetland to upland transition (no fill). Figure 2 shows the of the transects and geographical features mentioned in this report. The wetland boundary was marked in the field with wooden stakes and blue flagging and later measured in the field by Buck Lane a representative of the Japanese International Baptist Church. For each transect and sample point, the intermediate-level approach was used to visually estimate percent vegetative cover for each plant species observed within a-foot radius for herbaceous ground cover and a 30-feet radius for trees and shrubs. For the 1987 CE Manual, all species were ranked (based on spatial cover for each vegetative layer), then the dominants species were selected and evaluated. For the 1989 Interagency Manual determination, both dominant species and others with a spatial cover equal to or more than 20 percent in the strata within the sampling radius were evaluated according to specified criteria. Soils and hydrology were evaluated at each of these points using a Dutch (mud) auger to examine the upper part of the soil profile and observe ground water levels (if present) within the upper 16 inches (1987 CE Manual) to 18 inches (1989 Interagency Manual). Typically, the test holes were dug to a depth of 24 inches or more to describe the fill material, topsoil and subsoil characteristics. DISCUSSION EXISTING ENVIRONMENT Vegetation Vegetation studies for this site were conducted in February and June 1992, so plant communities on the site can be described only by species that were identifiable during those visits. Plant community composition reflects that the area was historically cleared, portions filled, and the upgradient creek was channelized. These factors change the informational value of the vegetation parameter for assessing wetland boundaries. For these reasons, vegetation as a factor was evaluated at face value for the 1987 CE Manual, but not weighed Post Office Box 3558 Jibc WL delin. 920619.rev PAGE 12 Portland.

Only the emergent meadow and scrub/shrub bottomland areas have more than 50 percent OBL, FACW, and/or FAC dominance. The transition from these communities to the grasslands is generally an abrupt one where there is fill material, and gradual for the native landscape. The transition is marked by an absence of ash trees, red osier dogwood, meadow (oxtail, sedges, rushes, and common hydrophytic forbs. Soils The soils for the study area were mapped by the SCS as Cove silty clay loam (mapping unit 13 on Figure 3), and Aloha silt loam (mapping unit 1).

The Aloha silt loam is a very deep, somewhat poorly drained soil formed in alluvium or lacustrine silt on broad valley terraces. The Urban fill is also present since portions of the site have been altered or obscured by urban works and/or structures. During the field study, the SCS soil delineations were checked and generally found in the same pattern as indicated in the soil survey, except the fill material was not identified by (or present) at the time of SCS mapping. Also, much of the Cove soil has been buried under fill material on the north side of the intermittent creek. The Cove silty clay loam is a very deep, poorly drained soil that formed in slightly concave areas along streams. The parent material consists of recent clayey alluvium (of mixed sources) and typically occurs on slopes usually less than 2 percent. The Cove topsoil on site is a very dark gray (10YR 311 or 5Y 2.5/1) silt loam and extends to a depth of 8 to 10 inches. This is underlain by a very dark gray or dark gray brown (5Y 2.511 or 2.5Y 412) silty clay loam subsoil that extends to a depth of 40 inches or more, and has many medium to large prominent dark brown to strong brown (7.5YR 3-4/4-6) mottles. The substratum consists of very dark gray clay or heavy silty clay loam that may show some mottling. The Cove soil is classified as Vertic Haplaquoll, which means it is a dark, wet, weakly-developed soil which forms deep wide cracks during the summer months. The Cove soil occurs in the lowest elevations on either side of the intermittent creek. The Aloha silt loam is a very deep, somewhat poorly-drained soil that formed on broad valley terraces. It generally has slopes of 0 to 3 percent and developed from alluvium or lacustrine silt. The Aloha topsoil generally has a dark brown (10YR 3/3) silt loam topsoil that extends to a depth of 8 inches. The underlying dark brown to dark yellowish brown (10YR 4/3-4) silt loam layer is typically 38 inches thick and is mottled throughout The Aloha soil type is classified as Aquic Xerochrept. It occurs only on the adjacent terrace slopes further south and north of the creek (Plot 4 on Transect 5).

Hydric characteristics (low chroma matrix and distinct mottling) were sometimes present in the Urban fill, but most likely originated offsite; thus, these characteristics were not evaluated. Jurisdictional wetlands must have hydric soils, which are soils that are saturated or flooded long enough during the growing season to develop anaerobic conditions. At the time of the field study, standing water or soil saturation at the surface was apparent in the bottomland soil (Cove) only. The field team concluded that the observed water table and soil saturation near the surface is present for the required time in early March (beginning of the wowing season). In terms of hydric soil characteristics, the soils only in these areas exhibited low chroma matrix with distinct mottling, and an aquic moisture regime with soil saturation within the criteria depth designated in both the 1987 CE Manual and the 1989 Interagency Manual. Topographically, these soils occupied lower positions in the landscape, relative to the fill material added to the remainder of the site. Generally those areas filled with more than 9 inches of imported material are effectively filled. The boundary between the upland and wetland soils is quite abrupt (as defined by the presence of the fill material) to gradual (as apparent by the native landscape). Hvdroloev The Japanese International Baptist Church site lies on an alluvial terrace with the south portion divided by a wide, flat bottomland with an intermittent creek. The portion of the site north of the creek has been significantly altered, including selective clearing, filling, upgradient channelization (in culvert), and nearby land development. At present, the source of water is mostly rainfall and runoff from upgradient lands. As discussed in the beginning of this report, the site has been significantly altered, including selective clearing, creek channelization, filling, dumping, and nearby land development. In evaluating these site alterations, the consultant team concluded the creek channelization and filling of the land just north of the intermittent creek have greatly reduced the degree of inundation and soil saturation in the native land over the past 11 to 7 years (approximate timing of filling).

On the basis of other wetland determinations in the Tualatin Valley, the consultant team concluded that the observed ponding and soil saturation near the surface persists for the required time in early March (beginning of the growing season). The areas where wetland hydrology is present include the remaining emergent grassland and scrub/shrub bottomland in the south part of the site, and a small remnant segment of emergent grassland between Tax lots 701 and 4400. The wetland hydrology indicators noted in these areas were soil saturation in the major portion of the root zone or at the surface, distinct mottling, concretions, and wetland drainage pattern. The boundary between wetland and non-wetland hydrology is generally abrupt as defined by the presence of fill. material, or gradual as evident in the native landscape. Ep lctions and Values Wetland functions and values of the site were evaluated for the Japanese International Baptist Church project. It was found to have low value for active recreation, passive recreation, nutrient retention/removal, on- and offsite runoff flood storage/desynchronization, sediment trapping, and food chain support. The site had low to moderate value wildlife habitat as it was a small, but significant area of scrub/shrub bottomland. The site had no functional value for the remaining wetland values and functions reviewed in the evaluation process, including endangered or threatened species habitat, fisheries habitat, ground water modification, unique/rare wetland, or shoreline stabilization. Several of these values could be enhanced by selectively removing blackberry brambles and removing old fill adjacent to the intermittent creek.

The following areas within the subject site satisfy the wetland requirements identified in both the 1987 CE Manual and the 1989 Interagency Manual: Q the remaining emergent grassland, A the scrub/shrub bottomland in the south part of the site; and A the small remnant segment of emergent grassland between the tax lots. The area of wetland at the site is 1.1 acres, which was calculated from field measurements of the wetland flagging (original map in Appendix Q. Federal and State Jurisdiction All of the wetlands identified on the site fall under the jurisdiction of the U.S. Army Corps of Engineers pursuant to Section 404 of the Clean Water Act, and the Oregon Division of State Lands under the Oregon Removal/Fill Law. The wetland boundary determined by the 1987 CE Manual is identical to the wetland boundary determined by the 1989 Interagency Manual. The Church would like to build a congregational complex consisting of buildings, landscaping, and parking. The proposed building would not necessarily fill any of the wetlands, but a small road crossing is needed to access Tax lot 4400 for parking. Present plans would require about 40 cubic yards to make this crossing near the northwest corner of Tax lot 4400. If the fill remains less than 50 cubic yards and other conditions are met, then no permit is necessary from the DSL. A permit application should be submitted to the CE for further review and determination if it meets a nationwide permit criteria. It is generally necessary that the wetlands be replaced or restored such that no net loss of wetland value (or acreage) occurs. Approval of any wetland fill permits will likely be based on the Church's proof that 1) no alternative site with less wetland impact is available in the vicinity; 2) that site design minimizes onsite wetland impacts; and 3) that any wetland mitigation is preferably situated onsite, rather than offsite.

The Act defines waters of the U.S. as follows: a. The territorial seas with respect to the discharge of fill material. b. Coastal and inland waters, lakes, rivers, and streams that are naviYgable waters of the United States, including their adjacent wetlands. C. Tributaries to navigable water of the United States, including adjacent wetlands. d. Interstate waters and their tributaries, including adjacent wetlands. e. All other waters of the United States not identified above, such as isolated wetlands and lakes, intermittent streams, prairie potholes, and other waters that are not a pan of a tributary system to interstate waters or navigable waters of the United States, the degradation or destruction of which could affect interstate commerce. Special aquatic sites The Environmental Protection Agency (EPA) defines Special aquatic sites as the following six categories in their Section 404 b. (1) guidelines (Federal Register 1980): a. Sanctuaries and refuges. d. Vegetated shallows. b. Wetlands. e. Coral reefs. C. Mudflats. f. Riffle and pool complexes. Nonwetlands "Uplands and lowland areas that are neither deepwater aquatic habitats, wetlands, nor other special aquatic sites. They are seldom or never inundated, or if frequently inundated, they have saturated soils for only brief periods during the growing season, and, if vegetated, they normally support a prevalence of vegetation typically adapted for life only in aerobic soil conditions." Nonwetlands have the following general diagnostic environmental characteristics: (1) Vegetation. The prevalent vegetation consists of plant species that are typically adapted for life only in aerobic soils. These mesophytic and/or xerophytic macrophytes cannot persist in predominantly anaerobic soil (2) Soil. Soils, when present, are not classified as hydric, and possess characteristics associated with aerobic conditions. (3) Hydrology. Although the soil may be inundated or saturated by surface water or ground water periodically during the growing season of the prevalent vegetation, the average annual duration. of inundation or soil saturation does not preclude the occurrence of plant species typically adapted for life in aerobic soil conditions. When any one of the diagnostic characteristics identified above is present, then the area is a nonwetland. Post Office Box 3558 Portland.

Humphrey Blvd. Portland, OR 97221 REPRESENTATIVE Denali Engineering, Inc. 15345 S.E. 82nd Drive, Suite 200 Clackamas, OR 97015 Lynn Harnisch, (503) 655-2971 LEGAL DESCRIPTION Tax Lots 701, 790, & 4400, Section 36, T1 S, R1W PROPOSAL Applicant proposes to construct a new, 8,310 square foot building for use as a church with associated parking area EXISTING CONDITIONS The site is 3.98 acres in size and includes a wetland of 1.11 acres. The site has frontage on S.W. Spruce Street on the north. S.W. Steven Street abuts the east side of the site. The property is surrounded by existing single family residences on the north, east, and west; land to the south is vacant and/or underdeveloped. The site was recently annexed to the City of Tigard. Zoning designation is R-7, similar to surrounding properties. • Japanese International Baptist Church - Page 1 a • • APPLICABLE CRITERIA AND STANDARDS PROCEDURES The procedures of quasi-judicial decision making incorporated into Chapter 18.32 will be used for this request. CRITERIA AND STANDARDS Chapter 18.52 R-7 Single Family Residential Buildings for religious assembly are permitted as conditional uses in the R-7 District (18.52.040.9). The maximum lot coverage for building and impervious surfaces is 80%. The building area is 8,310 square feet and the parking/drive area is 49,620 square feet, or 33% ofthe total site area of 173,561 square feet (3.98 acres). • Minimum yard setbacks are 15 feet for the front yard setback, 5 feet for side yard setbacks, and 15 feet for the rear yard setback. These required yards may be modified by additional requirements of 18.96 and 18.100.130, discussed in following sections. Maximum building height is 35 feet; the church building is proposed to be approximately 24 feet high, equivalent to a two story house. Chapter 18.130 Conditional Use The proposed church is reviewed as a conditional use in the R-7 District. A pre application conference was held with City of Tigard staff on July 21, 1994. Standards for approval are listed in this chapter in 18.130.040: The Hearings Officer, shall approve, approve with conditions, or deny an application for a conditional use.. based on findings of fact with respect to each of the following criteria: 1. The site size and dimensions provide adequate area for the needs of the proposed • use; Japanese International Baptist Church - Page 2 • • 10 2. The characteristics of the site are suitable for the proposed use considering size, shape, location, topography, and natural features; 3. All required public facilities have adequate capacity to serve the proposal; 4. The applicable requirements of the zoning district are met except as modified by this chapter; S. The supplementary requirements set forth in Chapter 18.114, Signs, and Section 18.120.180, Approval Standards, if applicable, are met; and 6. The use will comply with the applicable policies of the comprehensive plan. APPLICANT'S RESPONSE TO CONDITIONAL USE CRITERIA The site was chosen for its location within a residential area, where it could best be able to serve its community. The site plan and landscaping plan demonstrate that the proposed building and parking area can be placed on the site, in compliance with requirements of the City's Zoning Code. The City has advised that all public facilities are available and have capacity to serve the site, or can be made satisfactory. Sanitary sewer crosses the property, from S.W. Steve Street. Water is available in S.W. Spruce. Storm drainage will be detained on site and treated before being released into the wetland and related drainage way. The S.W. Spruce frontage will be improved with half street, curb, and sidewalk to appropriate standards.' Applicable standards of the zoning code are discussed in the following sections of this narrative. The Church proposes to install a sign at the Spruce Street entrance to the property. The sign will comply with all size and placement requirements. A separate permit will be requested when the sign is to be installed. The applicable Approval Standards listed in 18.120.180.1 include the following: 40 1S.W. Spruce is a Washington County owned and maintained public right of way. Japanese International Baptist Church - Page 3 9 • Chapter 18.84 Sensitive Lands A portion of the site has been identified as a wetland. The "wetland" was created by failure of previous land owners to maintain the drainage way west from the culvert at the west end of S.W. Steve Street. Water was impounded by poor drainage conditions on the subject property and properties to the west, and the wetland was created. Minimal disturbance of the wetland is proposed: The on site driveway must connect the north parking area to the south parking area and, in addition, provide an emergency access by way of S.W. Steve Street. The road was located along the edges of the property to minimize intrusion into the wetland area. A total of 3,536 square feet of the 48,390 total area of the wetland will be removed for construction of the road and building; 5,358 square feet will be created for mitigation. Proposed development activities in the identified wetland will • not alter present drainage patterns. The existing culvert in S.W. Steve Street will be extended under the proposed driveway along the east property line, approximately 25 feet. Water will continue to flow from the culvert into the existing drainage way and wetland. Appropriate permits will be sought from the Oregon Department of State Lands and/or Army Corps of Engineers. The Applicant's overall intention is to maintain the wetland in an undisturbed condition. Earlier site plans had no intrusion into the delineated area. The present proposal is an attempt to balance the requirements for parking and emergency access with the requirement to avoid development of wetland areas. As mitigation, the Applicant proposes to add approximately 800 square feet to the total wetland area. Chapter 18.94 Manufactured/Mobile Home Regulations - does not apply. Chapter 18.92 Density Computation - does not apply. 0 Chapter 18.144 Accessory Use and Structures - does not apply. Japanese International Baptist Church - Page 4 • • Chapter 18.96 Additional Yard Area Requirements - does not apply. Chapter 18.98 Building Height Limitations; Exceptions - does not apply. Chapter 18.100 Landscaping and Screening Please refer to the proposed landscaping plan for details on plant locations and varieties. Buildings used for religious assembly are not listed in the buffer matrix; therefore no extraordinary measures are required to be taken around the building.2 Parking areas are required to be screened (18.100.110). The Applicant believes that the buffer matrix requirement for "4-50 parking spaces" should apply, as the parking area consists of two distinct, separated areas, each with less than 50 spaces each (18.100.130 Buffer Matrix). The requirement is a 10 foot setback with screening as specified in 18.100.110. In addition, street trees will be installed along the S.W. Spruce Street frontage and along the private driveway as specified in 18.100.030 and 18.100.035. Chapter 18.102 Visual Clearance Areas The provisions of this section apply at the intersection of the driveway with S.W. Spruce Street. Proposed plantings will comply with requirements of this section and will not exceed three feet in height within a 30 foot triangle formed by the property line and the line of the driveway. Please refer to the landscaping plan for plant locations and varieties in the visual clearance area. Chapter 18.106 Off Street Parking and Loading Buildings used for religious assembly are required to provide one parking space for every 3 fixed seats or 6 feet of bench length or 2Chapter 18.42 Use Classifications includes "Religious Assembly" as a "Civic Use Type" (18.42.8.1 1). Japanese International Baptist Church - Page 5 0 0 every 50 square feet of floor space in the assembly area, which ever is greater. The main assembly area is 3,074 square feet with 240 non-fixed seats anticipated. The parking requirement is 80 spaces. Eighty (80) parking spaces are provided. The Zoning Code requires that one lockable bicycle space be provided for each 15 parking spaces (in this instance, 6 bicycle spaces), unless it can be shown that bicycle parking would not normally be necessary. The Applicant proposes a church, a use that typically draws persons dressed in clothing not suitable for bicycle riding. The Applicant believes that very few, if any, church members will arrive by bicycle. If bicycles are used by church members, provisions can be made adjacent to the church building. Parking stalls and aisles will meet the minimum dimensions • specified in 18.106.050. Please refer to the site plan for details. Chapter 18.108 Access, Egress, and Circulation The Applicant proposes a primary access to be-from S.W. Spruce Street. The identification sign will be located on this frontage. The Applicant proposes that the second frontage, where the S.W. Steve Street abuts the site, be blocked in a manner to permit only emergency vehicle access. Persons who attended a public meeting on August 3, 1994, at Tigard City Hall, voiced near unanimous concern that the construction of a driveway from S.W. Steve Street to S.W. Spruce Street would create a short cut for traffic, thereby causing increased out of area trips through the neighborhood and across the church's property. The Applicant believes that blocking S.W. Steve Street as proposed is the best solution, because a public street extension is not necessary to provide access either to the south portion of Tax Lot 4400, Tax Lot 1000 to the south, or adjacent properties. Please refer to the Future Street Plan map included with this submission, Japanese International Baptist Church - Page 6 • • • that demonstrates that adjacent properties are either developed or have other means for access.3 A walkway will be constructed adjacent to the on site driveway, to permit pedestrian movements between the two adjacent public streets, the parking area south of the wetland, and the church building. Chapter 18.114 Signs - please refer to preceding discussion relating to signs. Chapter 18.150 Tree Removal - Four trees with a trunk diameter exceeding six inches are proposed to be removed, including two fruit trees, one walnut, and one Western Red Cedar. Criteria for Issuance of Permits are listed in 18.150.030: A.I. None of the trees is dead or obviously diseased. A.2. The trees must be removed so that the building and parking area can be constructed as proposed. Moving these elements to other parts of the site to avoid the four trees would endanger others and the wetland. A.3. The site is nearly flat, so trees do not need to be retained for reasons of topography. A.4. The four trees do not serve as windbreaks for other trees, as far as can be determined. A. 5. The aesthetic character of the area will not be harmed by removing four trees. Other mature trees will remain on the site and landscaping will be added around the building and around the property's perimeter. A.6. Numerous trees and other plants will be added as the site is developed. Please refer to the landscape plan for details. Chapter 18.164 Street and Utility Improvement Standards Improvements to S.W. Spruce Street's frontage will be constructed to appropriate standards. No extension of S.W. Steve 318.1 64.030.F. 1 requires a Future Street Plan in conjunction with a land division. No land division is proposed, therefore the Applicant believes that, technically speaking, a Future Street Plan is not required for this proposal. However, the Applicant has provided sufficient information for the City to verify the conclusion that an extension of S. W. Steve Street is unnecessary. Japanese International Baptist Church - Page 7 0 9 • Street is proposed, as discussed in a previous section of this narrative. A cul de sac should not be necessary to terminate S.W. Steve Street on the Applicant's property because the public street is approximately 143 feet in length from its intersection with S.W. 83rd Street and provides driveway access for only three residences (two residences have frontage and access only on S.W. Steve Street). Also, if a cul de sac was to be constructed on the Applicant's property, considerably greater area of intrusion would be required into the wetland than is now proposed. 18.120.180.2 - Requires generally that buildings shall be located to preserve existing natural features. The Applicant has made every effort to avoid the identified wetland, intruding into the delineated area only as necessary to provide a driveway connection to the south parking area and an emergency vehicle connection to the west end of S.W. Steve Street. No trees will be removed and grading will be the minimum necessary • to provide for the building foundation, parking, and on site driveway. 18.120.180.3 - Requires offsets in the vertical face of certain residential structures; this section does not apply. 18.120.180.4 - Requires appropriate buffering and screening. Please refer to discussion in response to the Landscaping and Screening standards of Chapter 18.100. 18.120.180.5 - Provides standards and criteria for residential buildings; this section does not apply. 18.120.180.6 & 7 - Requires private outdoor areas for residential uses; these sections do not apply. 18.120.180.8 - Requires dedication of land for greenway purposes adjacent to the 100 year flood plain; no flood plain has been identified on this property. 18.120.180.9 & 10 - Requires measures for crime prevention: The Applicant proposes on site lighting in the parking areas and around the building as a means to thwart unauthorized activities. Lighting will be oriented to avoid glare onto adjacent properties. Japanese International Baptist Church - Page 8 • • • 18.120.180.11 - Access and circulation comply with other sections of the Zoning Code, as previously discussed. An on site pedestrian pathway will link the public street, the church building, and both parking areas. 18.120.180.12 - Neither S.W. Spruce Street nor S.W. Steve Street have public transit. 18.120.180.13 - Parking areas are designed in accordance with Code requirements, as previously discussed. 18.120.180.14 - Landscaping will be designed and installed in accordance with Chapter 18.100 (please refer to landscaping plan). Of the total site area of 3.98 acres, 8,310 square feet is covered by building (0.19 acres) and1.13 acres will be parking and driveway, leaving 2.16' acres or 62% of the site either formally landscaped or remaining in natural condition (primarily, the wetland). 18.120.180.15 - Drainage plans are included with this submission. Storm water from the developed site will be detained and treated before release to the existing drainage way through the wetland. 18.120.180.16 - Four handicapped parking spaces are provided immediately adjacent to the church building. 18.120.180.17 - Signs will be in accordance with requirements of Chapter 18.114. A separate permit application will be submitted for the proposed sign adjacent to S.W. Spruce Street. 18.120.180.18 - The Applicant believes that the plans and narrative submitted to the City of Tigard demonstrate that all requirements of the City's Code are met or can be met with conditions of approval. Finally, the Applicant notes that provisions are made within the City's Zoning Code to permit places of religious assembly. The Applicant concludes that the City intends these facilities to be part of the fabric of neighborhoods and the community. Therefore, the proposed church complies with the policies of the comprehensive plan. Japanese International Baptist Church - Page 9 0 0 s CONCLUSION The Applicant's submitted narrative and plans demonstrate that all requirements of the City's Code either are met or can be met through conditions of approval. Therefore, the Applicant requests that the proposal be approved as submitted. • • Japanese International Baptist Church - Page 10 0 0 • Letter of Authorization WHEREAS: The Japanese International Baptist Church is the owner of record of property in the NW 1/4 and the SW 1/4, Sec 36, T1S, R1W W.M., City of Tigard and Washington County, Oregon; AND WHEREAS: The Japanese International Baptist Church wishs to apply to the City of Tigard for a Development Permit to construct Church facilities on said property and request the annexation of one parcel into the City of Tigard; THEREFORE: The Japanese International Baptist Church hereby grants to Denali Engineering, Inc., 15345 SE 82nd Drive, Suite 200, Clackamas, Oregon 97015 the right to act as representative in the attached application(s) and approval process.

This presentation was interrupted by a number of the neighbors present at the meeting. The primary concern was the extension of S.W. Steve Street terminating with a cul-de-sac within the property belonging to the Church. The neighbors absolutely did not want any extension of S.W. Steve Street, particularly those currently living on S.W. Steve Street. The overall concept of extending S.W. Steve Street to provide for a through street was discussed. The neighbors did not see any reason why the street should be extended nor any land that would be served by an extension. Mr. Frank Wood, IMF Development, Inc. explained the size, configuration, seating and other architectural aspects of the church building. Ms. Allison McPherson, Alterra, Inc., presented the conceptual landscape plan. The landscape plan seemed to be acceptable by the neighbors.

Only the Cove soil type, found at the lowest elevations on the south part of the site, is considered hydric. An aquic moisture regime, low chroma matrix, and distinct mottling are all apparent in this soil type. HYDROLOGY: The Japanese International Baptist Church site lies on an alluvial terrace with the south portion divided by a wide, flat bottomland with an intermittent creek. The portion of the site north of the creek has been significantly altered, including selective clearing, creek channelization, filling, and nearby land development.

The study area is bounded by Southwest Spruce Street to the north and by residential properties in the remaining directions. Most of the surrounding lands have already been partially filled or developed for residential use (Figure 1). bite Use Present and Pam Presently the property is vacant and its condition reflects a history of disturbances, including selective clearing, upgradient creek channelization (culvert), filling, and dumping. The Church acquired the property from the previous owner who used the land as a rural junkyard. That owner presumably filled the south portion of the lot just north of the intermittent creek. The fill material is composed of mixed materials and varies in depth from 1 to more than 3 feet thick. Over the past several years since the Church has owned the property, the congregation has removed nearly all of the junk left behind by the previous owner. The Church has never placed any additional fill on any portion of the site. Regulatory Backsround Wetlands, whether they are marshes, bogs, wet meadows or bottomlands, can provide essential habitats for wildlife, provide flood protection through absorption of storm water, improve water quality by retention of sediments and add scenic diversity and aesthetic value to the landscape. To curb loss of wetland acreage, federal and state legislation exists to preserve wetland values and functions. The Clean Water Act (33 U.S.C. 1344) was enacted by the U.S. Congress to maintain and restore water quality, biological integrity and chemical balance of all Water of the United States. The Act empowered the U.S. Army Corps of Engineers (CE) with a jurisdiction over filling of wetlands and authorized the U.S. Environmental Protection Agency (EPA) to oversee the CE fill permitting process.

In January 1987, the Corps of Engineers WetlMl s Delineation Manual was issued to provide technical guidelines for identifying wetlands, and provide supporting information and methods for applying the technical guidelines. This manual was later revised and adopted in January 1989 by the CE, EPA, U.S. Fish and Wildlife Service (USFWS), and Soil. Conservation Service (SCS) as the Federal Manual for Identifving and Delineating ,Lurisdictional Wetlands. For administrative and political reasons, the federal regulatory agencies currently relies on the 1987 CE Manual as their official delineation procedure, while the DSL uses the 1989 Interagency Manual for delineations. Definitions Wetlands The Clean Water Act and both wetland Manuals define wetlands as: "Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, hogs, and similar areas." (33 CFR 323). Nonwetlands The 1987 CE Manual for clarification defines nonwedands as uplands and lowlands that are rarely to frequently inundated, have saturated soil conditions for a very short time in the growing season and support nonhydrophytic vegetation adapted to aerobic soil conditions. Appendix A includes a more detailed definition and lists the diagnostic conditions that typify a nonwetland.

The classification system begins with five broad classes Marine, Estuarine, Riverine, Lacustrine, Palustrine that further break down into many subclasses defined by water regime, substrate condition, vegetation cover, and human-influenced factors. The National Wetlands Inventory (NWI) maps identify these natural resources as overlays to U.S.G.S. quadrangle maps The accuracy of the NWI maps is limited, since the mapping utilized high-resolution aerial photographs and topographic data as the primary basis for wetland identification. Consequently, the NWI rarely identify agricultural wetlands, disturbed. wetlands, very small seasonal wetlands and urbanized (remnant) wetlands, even though these are true jurisdictional wetlands. Generally, onsite field study is necessary to confirm the presence or absence of NWI-identified wetlands, in addition to defining the jurisdictional boundary. MANDATORY CRITERIA AND INDICATORS The premise of a jurisdictional wetland focuses on having all of the following criteria (or diagnostic environmental characteristics), as defined in both manuals: Vegetation: A prevalence of vegetation typically adapted for life in saturated soil conditions (hydrophytic vegetation). Hydrophytic species, due to morphological, physiological, and/or reproductive adaptation(s), have the ability to grow, effectively compete, reproduce, and/or persist in anaerobic soil conditions. Soil: Soils are present and have been classified as hydric, or they possess characteristics that are associated with reducing soil conditions.

Under normal circumstances, both delineation manuals require that positive indicators of wetland hydrology, hydric soil and hydrophytic vegetation be present for an area to qualify as wetland. Many natural situations exist where one or two of the evaluation parameters have positive indicators, but remaining indicator(s) is misleading. For example, low chroma matrix colors may reflect the soil mineralogy instead of anaerobic conditions and many wetland plant species can grow in non-wetland environments. Furthermore, hydric soil indicators or hydrophytic plant dominance may persist long after the wetland hydrology has changed due to local/regional flood control, historic/pre-jurisdictional draining or surrounding development. For these reasons, the manuals require positive indicators of all three • parameters to ensure consistent and technically accurate wetland delineations. There are circumstances when one or more of the mandatory wetland criteria are not present as a result of natural events or human activities. Natural events, like river course changes, avalanches, or beaver dams, may create new wetlands that lack a predominance of hydrophytic vegetation or hydric soil characteristics. Human activities, such as ditching (or tile draining), filling, diversion construction (berms or levees), irrigation, grading or clearing, may obscure or disguise some of the mandatory wetland criteria. In these or similar situations, both manuals have provisions to define the wetland based on fewer parameters. Specifically, the 1987 CE Manual considers unauthorized filled or drained wetlands, newly- formed wetlands (by natural event) and human-induced wetlands as atypical wetlands, which by definition lack one or more of the mandatory criteria. The 1989 Interagency Manual I renamed this category to disturbed wetlands and expanded it to include wet agricultural lands, wet pastures, wet lowlands, and recently-cleared wetlands. Both manuals also identify the following problem area wetlands which might lack hydrophytic plant dominance during the later part of the growing season, and/or have marginal or no hydric soil characteristics: Wetlands on glacial till, variable seasonal wetlands, prairie potholes, • vegetated flats, interdunal swale wetlands, vegetated river bars and adjacent flats, caprock limestone wetlands, newly created wetlands, entisols, red parent material soils, spodosols, Post Office Box 3558 Jibc WL delin. 920330.rev PAGE 4 Portland, Ore. 97208 (503) 224-28 L I 0 0 PS 70 L E S JAPANESE INT'L BAPTIST CHURCH WETLAND REPORT ASSOCIATES SOIL WAR71 d 1VETLLN175 Sc[umsrs mollisols and wetlands dominated by facultative upland species (the later eight categories apply to the 1989 Interagency Manual only). Atypical, disturbed and problem area wetlands generally need additional site study to confirm the wetland boundary. HYDROPHYTIC VEGETATION Definitions The 1987 CE Manual defines hydrophytic vegetation "as the sum total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present." The 1989 Interagency Manual defines hydrophytic vegetation as "macrophytic plant life growing in water, soil or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content." The presence of a few individual hydrophytic plants amidst an upland plant community is not evidence of hydrophytic vegetation or visa versa. Ve ion Criteria and Indicators Hydrophytic vegetation develops in areas having hydrologic, geologic, topographic and climatic conditions which form an anaerobic growing environment in saturated soil. For both manuals, the hydrophytic vegetation criteria is met when the dominant species comprising the plant community are typically adapted to saturated soil conditions. The manuals specify an area has hydrophytic vegetation when more than 50 percent of the dominant species from all strata are designated on national or regional lists as obligate (OBL), facultative wetland (FACW) or facultative (FAQ. Table 1 describes the frequency in which each of these categories occur in wetlands. For Oregon and Washington, the National List of Plant Species That Occur in Wetlands: Northwest tRg%!ion 91 (Reed, 1988) compiled by the USFWS assigns one of these ratings to indigenous and introduced plant species.

Since the list does not focus on upland species (far too many to include), a not listed (NQ designation is used and is normally inferred to be an upland (UPL) species. The 1989 Interagency Manual alternatively permits the use of a frequency analysis of • species within a designated area to qualify as hydrophytic vegetation if the prevalence index value totals 3.0 or more, provided the hydric soil and wetland hydrology criteria are met. In addition to the plant dominance criteria described above, the 1987 CE Manual allows the following indicators to be used as positive indicators of hydrophytic vegetation: visual observation of plants species growing in areas of prolonged inundation and/or soil saturation, morphological plant adaptations, technical literature which document the presence of specific plant species in saturated soils for long periods, physiological adaptations, and reproductive adaptations. HYDRIC SOIL Definitions Soil has many definitions, but for the purposes of wetland delineation it is considered • the "unconsolidated natural material that supports, or is capable of supporting plant life." Soils are composed of varied percentages of organic and mineral fractions sand, silt, clay and rock fragments. Both delineation manuals define hydric soil as one "that is saturated, flooded or ponded long enough during the growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic vegetation." The 1987 CE Manual defines the duration of saturation, flooding, or ponding as 5 and 12.5% of the growing season, while the 1989 Interagency Manual defines this as seven days or more in the growing season.. Both manuals concur that the growing season begins when the soil temperature rises above 41 degrees F and ends when the soil temperature drops below this "biological zero". For the lower elevations of the Tualatin Valley, the growing season (on the average) begins March 1 and ends October 31.

Soils in Aquic suborders, Aquic subgroups, Albolls suborder, Salorthids great group, or Pell great groups of Vertisols that are: a. somewhat poorly drained and have water table less than 0.5 feet from the surface for a significant period (usually a week or more) during the growing season, or b. poorly drained or very poorly drained and have either: (1) water table at less than 1.0 feet from the surface for a significant period (usually a week or more) during the growing season if permeability is equal to or greater than 60 inches per hour in all layers within 20 inches, or (2) water table at less than 1.5 feet from the surface for a significant period (usually a week or more) during the growing season if permeability is less than 60 inches per hour in all layers within 20 inches, or 3. Soils that are ponded for long duration or very long duration during the growing season; or 4. Soils that are frequently flooded for long duration or very long duration during the growing season." This criteria encompasses both drained or undrained soils, so only those hydric soils which support hydrophytic vegetation and have positive wetland hydrology indicators are considered wetland soils. Drained hydric soil, that which no longer supports hydrophytic vegetation, can be characterized by the presence of dikes or levees, ditches or subsurface drains, flood control and upgradient diversions of runoff or ground water flow. Over time, soil profiles develop diagnostic horizons (layers) and color patterns that • reflect environmental influences. Climate, organisms, parent material, topographic relief and time are considered the primary influences in soil formation.

Most organic soils (Histosols) are hydric, while mineral soils tend to develop one or more of the following characteristics when associated with a reducing environment: Histic epipedon (organic surface horizon), hydrogen sulfide odor and other sulfidic material, aquic moisture regime (oxygen-deficient soil saturation), reduced soil conditions, gleyed soil matrix color, low chroma matrix color with or without bright mottling, soil series on hydric soil lists, and segregated iron and manganese concretions. Hydric sandy soils may lack these characteristics, but may have a high organic matter content in the surface horizon, organic matter streaking in the subsoil, and illuviated organic and/or spodic horizons. HYDROLOGY Definitions The 1987 CE Manual defines wetland hydrology as "areas that are periodically inundated or have soils saturated to the surface at some time during the growing season." This definition includes all those areas where the surface and/or ground water has an overriding influence on the soils and vegetation by facilitating anaerobic conditions. The 1989 Interagency Manual defines wetland hydrology in a similar manner. Both manuals concur that hydrology is the driving force of wetland creation, and as an evaluation parameter it is often the least precise and most difficult to document due to seasonal changes in soil saturation, ponding, and flooding. Criteria Like soil formation, climate, topography, stratigraphy, soil permeability, plant cover, and land use all influence soil wetness. The duration of soil saturation and/or inundation varies due to seasonal fluctuations of the ground water, precipitation events and flooding, surface ditches and/or subsurface tiling, local and/or regional flood control, and adjacent land Is use.

METHODS Both manuals prescribe similar methods to define the wetland boundaries based on offsite and onsite evaluations, and different degrees of study (routine, intermediate, and comprehensive). Offsite inspections are commonly done for wetland inventories or when only an approximation is needed for a particular purpose. Onsite inspections are done when a precise wetland boundary is needed to assess potential impacts from new development, change of land use or simply total the wetland acreage for a specific area. The standard routine level approach generally involves assembling existing information (maps, aerials, etc.) and an onsite inspection/study to conclude on the location of the wetland boundary. The comprehensive-level approach is infrequently needed, since it applies to very complex situations and requires extensive field research and data analysis to complete. More commonly, the Routine, Level 2 (1987 CE Manual) and intermediate-level (1989 Interagency Manual) approaches are utilized since they incorporate more field study than the standard routine level methods, and they usually determine the wetland boundary using site-specific data.

For • regulatory purposes, the subject site was determined to have normal circumstances, since the site was hydrologically altered more than 5 years ago (previously discussed). The site has remained undisturbed, except for hand-removal of junk auto parts left behind by the previous owner. The field observations were recorded on data sheets (Appendix B), and the wetland determinations are summarized in the following report text. Two transects were established to document existing site conditions and locate the wetland boundary. Transect 1 was located parallel to the west property line, which includes sample plots in native soil and fill material. Transect 2 was set on the east side of the site and through a remnant segment of land that did not get filled (unlike surrounding land) to document similar native and fill conditions there. Figure 2 shows the of the transects and geographical features mentioned in this report. The wetland boundary was marked in the field with wooden stakes and blue flagging and later measured in the field by Buck Lane, Japanese International Baptist Church representative. For each transect and sample point, the intermediate-level approach was used to • visually estimate percent vegetative cover for each plant species observed within a 5-foot radius for herbaceous ground cover and a 30-feet radius for trees and shrubs. For the 1987 CE Manual, all species were ranked (based on spatial cover for each vegetative layer), then the dominants species were selected and evaluated. For the 1989 Interagency Manual determination, both dominant species and others with a spatial cover equal to or more than 20 percent in the strata within the sampling radius were evaluated according to specified criteria. As an "off-season" delineation, other plant species may exist, but were not present or identifiable. For both manuals, species dominance was broadly estimated, since the field work was conducted during winter months. Soils and hydrology were evaluated at each of these points using a dutch (mud) auger to examine the upper part of the soil profile and observe ground water levels (if present) within the upper 16 inches (1987 CE Manual) to 18 inches (1989 Interagency Manual). Typically, the test holes were dug to a depth of 18 inches or more to describe the topsoil and subsoil characteristics.

WATER & WETIANM SCIENTISTS DISCUSSION EXISTING ENVIRONMENT Vesetation Field studies for this site were conducted in February 1992, so plant communities on the site can be described only by species that were identifiable in the winter. In addition, the area was historically cleared, filled to some extent, and the upgradient creek was channelized, all of which further change the plant community composition and complicate the identification process. These two factors, winter assessment and historic disturbances, change the informational value of the vegetation parameter for assessing wetland boundaries. Identifying the plant community composition is necessary for the wetland assessment, but composition in the grassed areas was somewhat less precise than it would be later in the • season. For these reasons, vegetation as a factor was evaluated at face value for the 1987 CE Manual, but not weighed as heavily as soils and hydrology parameters in making the boundary determinations for the 1989 Interagency Manual. The site has the following major plant communities: emergent meadow, grassland on fill material, and scrub/shrub bottomland. Emergent Meadow. This community remains only along the west and east edges of the site adjacent to filled areas as observed at Plots 2 and 3 on Transect 1, and Plots 2 and 3 on Transect 2.

If not controlled, the fill material would probably support more dense brambles of Himalayan blackberry (Rubes discolor, FACU-) and clustered wild rose (Rosa pisocarga, FACU) as apparent in nearby areas during the field study. Scrub/Shrub Bottoml Id. This community occupies the abandoned land adjacent to creek and in the extreme south portion of the site. Species identified during the field study include wild rose (Rosa sp., FACU), Oregon ash saplings (FACW), soft rush (,l_uncua gfusus, FACW+), red osier dogwood (Corpus stolonifera, FACW), hawthorn (_ratac%U dou lasii, FAC), mixed grasses, and trailing and Himalayan blackberry (R.ubus ursinus, NL and R. discolor, FACU-). No sample plot was described for this community because of the obvious hydrophytic plant dominance. Composition of the dominant species in jurisdictional wetlands must be more than 50 percent obligate wetland (OBL), facultative wetland (FACW) and/or facultative (FAC) species, while the adjacent upland areas have less than 50 percent of such dominance. Given the limitations of an "off-season" determination (as described above), only the emergent meadow and scrub/shrub bottomland areas have more than 50 percent OBL, FACW, and/or FAC dominance. The transition from these communities to the grasslands is generally an abrupt one (due to old fill), and is marked by an absence of ash trees, red osier dogwood, sedges, rushes, and common hydrophytic forbs. Soils The soils for the study area were mapped by the SCS as Cove silty clay loam (mapping unit 13 on Figure 3), and Aloha silt loam (mapping unit 1). These soils are described in detail in the Soils of Wigton Countv . OrePann (Green, 1982). The Cove silty clay loam is a very deep, poorly drained soil, formed in recent clayey alluvium on • slightly concave areas along streams on floodplains. The Aloha silt loam is a very deep, somewhat poorly drained soil formed in alluvium or lacustrine silt on broad valley terraces.

During the field study, the SCS soil delineations were checked and generally found in the same pattern as indicated in the soil survey, except the fill material was not identified by (or present) at the time of SCS mapping. Also, much of the Cove soil has been buried under fill material on the north side of the intermittent creek. The Cove silty clay loam is a very deep, poorly drained soil that formed in slightly concave areas along streams. The parent material consists of recent clayey alluvium (of mixed sources) and typically occurs on slopes usually less than 2 percent. The Cove topsoil on site is a very dark gray (10YR 3/1 or 5Y 2.5/1) silt loam and extends to a depth of 8 to 10 inches. This is underlain by a very dark gray or dark gray brown (5Y 2.5/1 or 2.5Y 4/2) silty clay loam subsoil that extends to a depth of 40 inches or more, and has many medium to large prominent dark brown to strong brown (7.5YR 3-4/4-6) mottles. The substratum consists of • very dark gray clay or heavy silty clay loam that may show some mottling. The Cove soil is classified as Vertic Haplaquoll, which means it is a dark, wet, weakly-developed soil which forms deep wide cracks during the summer months. The Cove soil occurs in the lowest elevations on the south portion of the site. The Aloha silt loam is a very deep, somewhat poorly-drained soil that formed on broad valley terraces. It generally has slopes of 0 to 3 percent and developed from alluvium or lacustrine silt. Although not sampled at the subject site, the Aloha topsoil generally has a dark brown (10YR 3/3) silt loam topsoil that extends to a depth of 8 inches. The underlying dark brown to dark yellowish brown (10YR 4/3-4) silt loam layer is typically 38 inches thick and is mottled throughout The Aloha soil type is classified as Aquic Xerochrept. It presumably occurs only on the adjacent terrace slopes at the site. The areas of fill are not identified on the SCS maps, but would currently be mapped as Urban fill. They are composed of mixed materials of unknown source). Color and texture vary with the sampling site, but drainage is much better than that of the native soils. Hydric characteristics (low chroma matrix and distinct mottling) were sometimes present in the Urban fill, but most likely originated offsite; thus, these characteristics were not evaluated.

At the time of the field study, standing water or soil saturation at the surface was apparent in the bottomland soil (Cove) only. The field team concluded that the observed water table and soil saturation near the surface would be present for the required time in early March (beginning of the growing season). In terms of hydric soil characteristics, the soils only in these areas exhibited low chroma matrix with distinct mottling, and an aquic moisture regime with soil saturation within the criteria depth designated in both the 1987 CE Manual and the 1989 Interagency Manual. Topographically, these soils occupied lower positions in the landscape, relative to the fill material added to the remainder of the site. The boundary between the upland and wetland soils is quite abrupt (again as defined by the presence of the fill material). Hydrology • The Japanese International Baptist Church site lies on an alluvial terrace with the south portion divided by a wide, flat bottomland with an intermittent creek. The portion of the site north of the creek has been significantly altered, including selective clearing, filling, upgradient channelization (in culvert), and nearby land development. At present, the source of water is mostly rainfall and runoff from upgradient lands. As discussed in the beginning of this report, the site has been significantly altered, including selective clearing, creek channelization, filling, dumping, and nearby land development. In evaluating these site alterations, the consultant team concluded the creek channelization and filling of the land just north of the intermittent creek have greatly reduced the degree of inundation and soil saturation in the native land over the past 10 years. Wetland hydrology is defined by the presence of permanent water inundation, seasonal inundation or soil saturation near the surface for a significant period during the growing season. On the basis of other wetland determinations in the Tualatin Valley, the consultant team concluded that the observed ponding and soil saturation near the surface would be present for the required time in early March (beginning of the growing season).

The wetland hydrology indicators noted in these areas were soil saturation in the major portion of the root zone or at the surface, distinct mottling, concretions, wetland drainage pattern, and hydric soil appearance (1989 Interagency Manual only). The boundary between wetland and non-wetland hydrology is generally abrupt as defined by the presence of fill material. Functions and Values Wetland functions and values of the site were evaluated for the Japanese International • • Baptist Church project. It was found to have low value for active recreation, passive recreation, nutrient retention/removal, on- and offsite runoff flood storage/desynchronization, sediment trapping, and food chain support. The site had low to moderate value wildlife habitat as it was a small, but significant area of scrub/shrub bottomland. The site had no functional value for the remaining wetland values and functions reviewed in the evaluation process, including endangered or threatened species habitat, fisheries habitat, ground water modification, unique/rare wetland, or shoreline stabilization. Several of these values could be enhanced by selectively removing blackberry brambles and removing old fill adjacent to the intermittent creek.

WA,FR & 5c3errnsrs Jurisdictional wetlands are defined by the "common area" where all three parameters 9 wetland hydrology, hydric soil and hydrophytic vegetation are present. The following areas within the subject site satisfy the wetland requirements identified in both the 1987 CE Manual and the 1989 Interagency Manual: A the remaining emergent grassland, A the scrub/shrub bottomland in the south part of the site; and A the small remnant segment of emergent grassland along the east property line. The area of wetland at the site is 0.60 acres, which was calculated from field measurements of the wetland flagging (original map in Appendix B). Federal and State Jurisdiction All of the wetlands identified on the site fall under the jurisdiction of the U.S. Army Corps of Engineers pursuant to Section 404 of the Clean Water Act, and the Oregon Division of State Lands under the Oregon Removal/Fill Law. The wetland boundary determined by the 1987 CE Manual is identical to the wetland boundary determined by the 1989 Interagency Manual. The Church would like to build a congregational complex consisting of buildings, landscaping, and parking. The proposed project would not necessarily fill any of the wetlands. If site plans change such that it would be necessary to fill any portion of these wetlands, then permits from the CE and DSL are required. It is generally necessary that the wetlands be replaced or restored such that no net loss of wetland value (or acreage) occurs. Approval of the permits will likely be based on the Church's proof that 1) no alternative site with less wetland impact is available in the vicinity; 2) that site design minimizes onsite wetland impacts; and 3) that any wetland mitigation is preferably situated onsite, rather than offsite.

WAM 8 wrums SCIENTISTS The breadth of Section 404 of the Clean Water Act applies to both deep-water aquatic habitats and special aquatic sites, including wetlands (Federal Ref>ister 1982). The Act defines waters of the U.S. as follows: a. The territorial seas with respect to the discharge of fill material. b. Coastal and inland waters, lakes, rivers, and streams that are navigable waters of the United States, including their adjacent wetlands. C. Tributaries to navigable water of the United States, including adjacent wetlands. d. Interstate waters and their tributaries, including adjacent wetlands. e. All other waters of the United States not identified above, such as isolated wetlands and lakes, intermittent streams, prairie potholes, and other waters that are not a part of a tributary system to interstate waters or navigable waters of the United States, the degradation or destruction of which could affect interstate commerce. Special aquatic sites The Environmental Protection Agency (EPA) defines Special aquatic sites as the following six categories in their Section 404 b. (1) guidelines (Federal Reeister 1980): a. Sanctuaries and refuges. d. Vegetated shallows. b. Wetlands. e. Coral reefs. C. Mudflats. £ Riffle and pool complexes. Nonwetlands "Uplands and lowland areas that are neither deepwater aquatic habitats, wetlands, nor other special aquatic sites. They are seldom or never inundated, or if frequently inundated, they have saturated soils for only brief periods during the growing season, and, if vegetated, they normally support a prevalence of vegetation typically adapted for life only in aerobic soil conditions." Nonwetlands have the following general diagnostic environmental characteristics: (1) Vegetation. The prevalent vegetation consists of plant species that are typically adapted for life only in aerobic soils. These mesophytic and/or xerophytic macrophytes cannot persist in predominantly anaerobic soil conditions.* (2) Soil. Soils, when present, are not classified as hydric, and possess characteristics associated with aerobic conditions. (3) Hydrology. Although the soil may be inundated or saturated by surface water or ground water periodically during the growing season of the prevalent vegetation, the average annual duration of inundation or soil saturation does not preclude the 0 occurrence of plant species typically adapted for life in aerobic soil conditions. When any one of the diagnostic characteristics identified above is present, then the Ps"COLES ASSOCIATES area is a nonwetland.

Part of the required parking spaces will be more than 200 feet from the building, owing to the location of the wetland and topography of the site. A variance is requested to Section 18.106.020.1-1, which specifies that required parking spaces be located not further than 20.0 feet from the building they serve. Japanese International Baptist Church Parking Variance Page 1 BACKGROUND INFORMATION EXISTING CONDITIONS The site is 3.98 acres in size. The site has frontage on S.W. Spruce Street on the north. S.W. Steven Street abuts the east side of the site. The property is surrounded by existing single family residences on the north, east, and west; land to the south is vacant and/or underdeveloped. The site slopes gently from its frontage on S.W. Spruce Street to its mid-section, where an intermittent stream/drainage ditch flows west from a culvert at the end of S.W. Steve Street. A regulatory wetland 1.11 acres in size has been created in and around this area, caused by failure of downstream property owners (to the west) to maintain a clear drainage channel. South of the wetland, the land rises more steeply to approximately the same elevation as at the north property line. The site was recently annexed to the City of Tigard. Zoning designation is R-7, similar to surrounding properties. REASON FOR THE VARIANCE The required parking for the proposed church is 80 spaces. Forty-eight of the spaces are located immediately adjacent to the building. Measured in a straight line from the closest corner of the building, five spaces are at a distance of approximately 240 feet and the remaining 27 spaces are nearly 400 feet away. Tigard Zoning Ordinance requires off street parking to be located within 200 feet of the building it serves (18.106.020.H). To locate the remaining spaces closer to the building would mean drastically altering the wetland and topography of the site or intruding into setback areas which are needed to maintain a buffer for existing residences. In addition, the logical area for wetland mitigation is the area to the north of the existing wetland, as the slope of the site is more gradual to the north of the wetland than on the south side. Japanese International Baptist Church Parldng Variance Page 2 4 APPLICABLE CRITERIA AND STANDARDS CRITERIA AND STANDARDS Chapter 18.106.020.H The Zoning Code requires off street parking to be located within 200 feet from "the building or use they are required to serve, measured in a straight line from the building." Thirty two of the 80 required parking-spaces are located more than 200 feet from the proposed church building. A variance is requested to this requirement. Chapter 18.134 VARIANCE The Director may grant a variance when the requirements of this chapter are met. 18.134.050 Criteria for Granting a Variance 1. The proposed variance will not be materially detrimental to the purposes of this title, in conflict with the policies of the comprehensive plan to any other applicable policies and standards, and to other properties in the same zoning district or vicinity. Response: The purpose of the zoning ordinance as applied to this circumstances would be to guarantee that adequate parking is provided in a location convenient to the use, so that neighbors would not be affected by undue congestion, noise, and so on. The proposed variance will not be materially detrimental: The congregation is presently small and is not expected to use all of the spaces provided adjacent to the building for several years. The use is isolated from surrounding neighborhoods on S.W. Spruce and S.W. Steve, so even a modest walk from the south parking area will be shorter than would be required by parking on adjacent streets. All of the required parking will be provided on site and all of the parking areas will be screened and landscaped. Japanese International Baptist Church Parking Variance Page 3 • The only deviation from requirements is that some of the required parking spaces will be greater than 200 feet from the proposed church building. 2. There are special circumstances that exist which are peculiar to the lot size or shape, topography or other circumstances over which the applicant has no control and which are not applicable to other properties in the same zoning district. Special circumstances that apply to this site include the wetland and the topography which directs the wetland mitigation to particular areas. These conditions were discussed in a previous section. The lot size and shape is long and narrow, and offset, with a street (S.W. Steve) abutting the property's east side. There is insufficient width to locate additional parking spaces in the vicinity of the church, without intruding into required setback and buffer areas. The applicant did not create this property in its present form and certainly did not create the wetland. No adjacent property is affected by these circumstances, to the same degree. An adjacent property to the west is almost entirely wetland and probably not usable. Residential lots surrounding this site have already been developed with homes. 3. The use proposed will be the same as permitted under this title... Churches are allowed as conditional uses in this district. Concomitant to the request for variance is an application for conditional use permit. 4. Existing physical and natural systems... will not be adversely affected any more than would occur if the development were located as specified in the title. Physical and natural systems will be affected if the variance is not approved: To be within 200 feet of the building, the required parking would have to be located in the wetland or in the area proposed for mitigation. The value of the wetland would be reduced or eliminated, Japanese International Baptist Church Parldng Variance Page 4 0 0 or would have to be replaced elsewhere on the site at much greater cost and much greater impact on the existing land conditions. The proposal to located required parking south of the wetland places the value of the wetland higher than the potential inconvenience to parishioners who might have to walk a little farther to attend services. 5. The hardship is not self-imposed and the variance requested is the minimum variance which would alleviate the hardship. As noted, the applicant did not create the wetland or the property in its present form and size. The applicant is attempting to design the project around the existing natural features and to incorporate these features into the site plan. The applicant believes that the requested variance is the minimum necessary and serves to balance the intentions of the code with the conditions of this site. CONCLUSION The Applicant's request for variance complies with all requirements of the City's Code and that, therefore, the variance should be approved.

W. Hall Blvd. Tigard, Or. 97223 Re: CUP 0007/VAR 94-0009/SLR 94-0005 Japanese Int'l. Baptist Church Dear Sir: • 11200 S. W. 83rd Avenue Tigard, Or. 97223 November 23, 1994 RECEIVED A v' 2 IS 1994 COMMUNITY DEVELOPMENT We, the undersigned, wish to protest the issuance of a variance for the above lasted property. The wetlands designation of this property, not only provides a sanctuary for a variety of wildlife, but acts as a sound barrier for the residents from the noise on Hall Blvd. and Hwy. 217. If you issue this variance, and the trees and shurbs are destroyed on this property, the quality of life for the residents east of these two main arteries will deteriorate dramatically. Too many of our buffer zones are being eliminated with no regard for the effect it is going to have on future generations. On these grounds alone, we protest this variance. Although we property owners have been assured that the only access to this church will be from Spruce St., it seems likely that a future var- iance will be requested for access from Steve St. once the church and parking lot are built. In an effort to prevent this, we wish to point out what a horrendous traffic problem will be created on S. W. 83rd and, potentially, S. W. 81st. There are no street lights in our neigh- borhood and any increase in traffic will create a real danger to children and pets. The City gave little consideration to o. the traffic congestion and pol- lution on Pfaffle when they approved construction of Cub Foods and Costco. Access to our neighborhool has becore a nightmare with outsiders trying to avoid Pacific Highway by cutting across Pfaffle to Hall Blvd. Even more traffic will be created by the people attending this church. We respectfully reque j.). 'op"Ze Bradley D. Tolliver 11207 S. W. 81st Tigard, Or. 97223 st that you deny the above variance request. Sincerely yours, Mrs. Kristen Miller S. L. Davidson 7960 S. W.

I own the home located at 8513 SW Lucille Court, which is probably the closest one to the proposed project. The homes on Lucille Court are on small lots. The side setback will probably place the church closer than 30 feet to my house. My concern is with an adequate visual and noise buffer. I would like to see an eight foot fence or berm with vegetative cover as part of the project. Also, I would like assurance that noise during church activities is controlled by noise barriers in the church design or an adequate setback to assure that noise associated with the church will not interfere with the tranquil enjoyment of my home. Thank you for your attention to my concerns. Sin erely, James R.
