BACKGROUND INFORMATION Site Description: The subject site includes one tax lot,WCTM 1S134CD00100,which is located on the east side of SW 12l Avenue between Merestone Ct and Katherine St.The parcel encompasses Summer Creek and is part of the Summer Creek Greenway. The property is owned by the city and is zoned Parks and Recreation (PR). The proposed work will also partially take place in the adjacent SW 121st Avenue right-of-way. Land uses surrounding the project area include single detached residences to the north and south and city-owned natural areas to the east and west. The project area also contains and is adjacent to numerous environmental resources, including Summer Creek, significant wetlands with associated vegetated corridors, and FEMA special flood hazard area. The existing 121"Avenue Bridge carries SW 121"Avenue across Summer Creek.Within the project area, SW Tigard Street is composed of two approximately eleven-foot-wide travel lanes with shoulders on each side for a total width of approximately 35 feet. Per the 2040 Tigard Transportation System Plan (TSP), SW 1215t Avenue is classified as a collector street. Proposed Request: The proposed project is identified in the City's Capital Improvement Plan as project#94057and includes: • Replacement of the SW 12151 Avenue bridge guardrail, foundation,and concrete footers. • Stabilization of the northeast and southeast creek banks through installation of riprap stone and vegetated slopes. • Replacement and extension of the deteriorating northeast and southeast wing walls. The northeast wall will be extended by six feet and the southeast wing wall will be extended by seven feet.The existing deteriorated storm sewer pipe will also be replaced and re-positioned to direct flows away from the wing walls. • Installation of riprap stone around both sanitary sewer manholes. • Installation of root wads at the base of the rip-rap stone on the northeast creek bank. • Clearing all sediment and debris from the northeast and southeast culverts. The purpose of the proposed project is to stabilize the eroding bank and replace deteriorating infrastructure to protect both city facilities as well as the privately owned residential property to the north. The proposed project will reduce erosion, sedimentation, and plant loss. In addition, stormwater and sanitary sewer infrastructure will be secured.The driveway at 11740 SW 121st Avenue will be better protected from damage or collapse due to bank erosion. Road safety will be ensured, as the road guardrail on SW 121st Avenue,along with its foundation and footers,will be replaced.Native vegetation will be planted, replacing the invasive vegetation that will be removed. Approximately 97 native trees, 1,226 native shrubs,and 100 native wetland plants (sedges,rushes,grasses)will be planted once construction is completed.

This amendment must be based on a specific development proposal. The STAFF RECOMMENDATION CMA2026-0001 /C-SLR2026-0001 SUMMER CREEK BRIDGE STABILIZATION PAGE 20 OF 26 effect of the amendment would be to remove Goal 5 protection from the property, but not to remove the requirements related to the CWS Stormwater Connection Permit, which must be addressed separately through an alternatives analysis, as described in Section 3.02.5 of the CWS "Design and Construction Standards."The applicant must demonstrate that such an amendment is justified by either of the following: B. ESEE analysis. The applicant may prepare an environmental, social, economic and energy (ESEE) consequences analysis prepared in compliance with OAR 660-23-040. FINDING: The applicant has chosen to demonstrate the amendment is justified through an ESEE analysis,rather than a demonstration that the wetlands are not significant. The applicant submitted an ESEE analysis dated March 2026 (Attachment 3) prepared in compliance with OAR 60-23-040,to justify removal of Goal 5 protection from approximately 1,331 square feet(0.03 acre) of significant wetlands and associated vegetated corridor. 1. The analysis must consider the ESEE consequences of allowing the proposed conflicting use, considering both the impacts on the specific resource site and the comparison with other comparable sites within the Tigard Planning Area; FINDING: As described in the ESEE analysis (Attachment 3), the applicant has considered the consequences of allowing the proposed conflicting use,in this case the proposed bridge and stormwater outfall repair and bank stabilization,and has considered the impacts on the specific resource site as well as other comparable sites within Tigard. As described in the applicant's analysis, the consequences of allowing the proposed conflicting use provide a net positive benefit by repairing and securing public infrastructure and protecting the adjacent private property by stabilizing the eroding bank. Since the proposal is specific to stabilizing the existing bank and repairing the existing bridge, there are no comparable sites within the Tigard Planning Area that can provide an alternative site with fewer impacts. This standard is met. 2. The ESEE analysis must demonstrate to the satisfaction of the city council that the adverse economic consequences of not allowing the conflicting use are sufficient to justify the loss, or partial loss, of the resource; FINDING:The ESEE analysis provided by the applicant demonstrates that the economic consequences of not allowing the conflicting use would be negative. As stated in the analysis, allowing the project to move forward will decrease the city's liability in the event of a motor vehicle crash impacting the guardrail on the northbound side of the bridge since the guardrail will be replaced along with secure concrete footers. Additionally, the project will decrease the city's liability for damages incurred involving the property located directly north of the bridge at 11740 SW 121st Avenue related to the driveway, motor vehicles parked in the driveway, or the fence and home, all of which are located near the north creek bank. Lastly, the proposed project includes the replacement of a broken stormwater outfall and stabilization of the creek bank around the two sanitary sewer manholes on the south creek bank, protecting critical utilities from further deterioration and preventing costly future repairs in the event of failure. For these reasons, prohibiting the conflicting use would result in negative economic consequences from impacts to the utilities, adjacent property, and additional expenses for repair and maintenance to the existing structure, which will continue to deteriorate should it not be replaced. This standard is met. STAFF RECOMMENDATION CMA2026-0001 /C-SLR2026-0001 SUMMER CREEK BRIDGE STABILIZATION PAGE 21 OF 26 3. The ESEE analysis must be prepared by a team consisting of a wildlife biologist or wetlands ecologist and a land use planner or land use attorney, all of whom are qualified in their respective fields and experienced in the preparation of Goal 5 ESEE analysis; FINDING: A qualified team consisting of land use planners, wetland scientists, and ecologists, all qualified in their respective fields with experience compiling such analyses,prepared the ESEE analysis submitted with this application as Exhibit C.This standard is met. 5. If the application is approved, then the ESEE analysis must be incorporated by reference into the Tigard Comprehensive Plan, and the "Tigard Wetland and Stream Corridor Map"be amended to remove the site from the inventory. FINDING: On approval of this request, the ESEE analysis will be incorporated by reference into the Tigard Comprehensive Plan, and the "Tigard Wetland and Stream Corridor Map" will be amended to remove protection from the subject portion of the site from the inventory. 18.790 TEXT AND MAP AMENDMENTS A.

Grading and Erosion Control: The City of Tigard and Clean Water Services Design and Construction Standards also regulate erosion control to reduce the amount of sediment and other pollutants reaching the public storm and surface water system resulting from development, construction, grading, excavating, clearing, and any other activity which accelerates erosion. Prior to commencing any site work, the applicant must obtain an Erosion and Sediment Control (ESC) Permit through the city of Tigard. The plan must comply to the "CWS Erosion Prevention and Sediment Control Design and Planning Manual" (current edition). The Federal Clean Water Act requires that a National Pollutant Discharge Elimination System (NPDES) erosion control permit be issued for any development that will disturb one or more acre of land. The area of disturbance is less than one acre. The following conditions of approval are required to meet this standard: • Prior to commencing any site work, the applicant must submit for an Erosion & Sediment Control (ESC) Permit. The plan must conform to the "CWS Erosion Prevention and Sediment Control Design and Planning Manual" (current edition). • Prior to commencing any site work, the applicant must submit a final grading plan showing the existing and proposed contours for approval. The plan must detail the provisions for surface drainage of all lots and show that they will be graded to ensure that surface drainage is directed to the street or a public storm drainage system approved by the Engineering Division. The design engineer must indicate areas that will have natural slopes between 10 percent and 20 percent, as well as areas that will have natural slopes in excess of 20 percent. This information will be necessary in determining if special grading inspections or permits will be necessary. Through the conditions of approval,this standard is met. SECTION VII.

SECTION VIII. AGENCY COMMENTS Clean Water Services issued a Service Provider Letter (CWS file 26-001070) for this proposal on June 5, 2026, and determined that this project will significantly impact the existing or potentially sensitive area(s) found near the site.The agency also submitted written comments,dated July 21,2026,requesting a condition of approval that requires the applicant to obtain Storm Water Connection Permit Authorization. This request has been incorporated into the conditions of approval. The City of Tigard and CWS have an intergovernmental agreement stating that the City will ensure implementation of CWS Design and Construction Standards;therefore,this approval is conditioned to satisfy CWS requirements. SECTION IX. ANALYSIS, CONCLUSION,AND RECOMMENDATION ANALYSIS: As shown in the analysis above, the applicant's ESEE analysis addresses the requirements of the Tigard Development Code, Chapter 18.510 Sensitive Lands. The subject property contains locally significant wetlands and vegetated corridors protected under Goal 5 safe harbor. The applicant has applied for a quasi-judicial comprehensive plan map amendment under a Type III-Modified procedure. The application is based on a specific development of repairs to the SW 121" Avenue bridge, bank stabilization,and utility repair.The applicant has demonstrated that such an amendment is justified by an ESEE analysis consistent with OAR 660-23-040. The ESEE analysis concludes that allowing the conflicting use to the bridge repairs, utilities, and bank stabilization would result in the most positive consequences of the decision options.A decision to allow the conflicting use will avoid many of the negative consequences attributed to either limiting or prohibiting the conflicting uses. Through the application of development standards to conflicting uses, the impacts on the significant wetland can be further minimized,and the remaining resource and off-site resource areas can be enhanced. There will be a relatively high level of economic, social, environmental and energy benefits achieved.Allowing the conflicting use offers the most benefit to the wetland(through restoration and enhancement) and to the community (safer utility and transportation infrastructure) and it strikes a balance between conflicting uses and the city's goals. CONCLUSION As demonstrated by the findings above,the Planning Commission finds,by a 7-0 vote in favor,that the proposed comprehensive plan map amendment and sensitive lands review comply with the applicable Statewide Planning Goals, applicable regional, state, and federal regulations, the Tigard Comprehensive Plan,and applicable provisions of the City's implementing ordinances. The Planning Commission recommends approval to the Tigard City Council of the proposed comprehensive plan map amendment and sensitive lands review.

EXECUTIVE SUMMARY The City of Tigard Department of Public Works is seeking a Comprehensive Plan Map Amendment to allow for the emergency repair of the guardrail,wingwalls,and stormwater outfall on the east side of the SW 121st Avenue Bridge,and the stabilization of the north and south banks of Summer Creek,to include the shoring of the creek bank immediately below the driveway at 11740 SW 121st Avenue and the road guardrail foundations on the SW 121st Avenue Bridge. The requested amendment would result in 0.010 acres (445.95 Sq. Ft.) of wetlands and 0.020 acres (884.49 Sq.Ft.)of vegetated corridor being removed from the Comprehensive Plan Map on the east side of the SW 121'Avenue Bridge. Once work is completed, the impacted wetland and vegetated corridor will be re-established with native species. All permanent impacts from the proposed work will be on the east side of the SW 121st Avenue Bridge. Temporary,construction related,impacts will be mitigated through the use of best practices promulgated by Clean Water Services (CWS), the Oregon Department of State Lands (DSL), and the Oregon Department of Environmental Quality (DEQ). Approximately 97 native trees, 1,226 native shrubs, and 100 native wetland plants (sedges, rushes, grasses) will be planted throughout the project area once construction is completed. These plantings will be done at the ratios and to the specifications required by CWS. 1.1 South Bank- Wetlands Approximately 0.010 acres (445.95 Sq. Ft.) of locally significant wetlands on the south side of Summer Creek will be impacted by the proposed work. These wetlands have been delineated on the as delineated on the City of Tigard Wetlands&Stream Corridors Map.t The proposed work, impacting these wetlands, includes the shoring of the road guardrail foundations on the SW 121 St Bridge, the extension of the existing concrete wingwall by seven feet, the installation of riprap stones and geocells in and around the exposed sanitary sewer manholes, and the replanting of wetlands plants. The herbaceous vegetation in these wetlands is "dominated by bird's-foot trefoil (Lotus corniculatus) and reed canarygrass (Phalaris arundinacea)."2 Both bird's foot trefoil and reed canarygrass are invasive species that outcompete natives, their predominance within the subject wetland area, highlight the wetlands' degraded condition. A full wetlands delineation, for the entire project area, was completed in June 2025 and can be found in Appendix A: June 2025 Wetlands Delineation. Once work is completed,the impacted wetland will be restored with native plants.All replanting will be done to the standards set forth by CWS, which are widely regarded as industry best practices.In simple terms,the wetland will be left better than it was found because of this project. 1 City of Tigard,Oregon, Wetlands&Stream Corridors: City of Tigard, Oregon,accessed 24Mar2026.Link. 2 Larsson,Ingrid and Feltus,Hallie, Wetland and Other Waters Delineation Report:Summer Creek Bank Stabilization Assessment and Design,WSP USA,Inc.,June 2025,Page 4. . Tigard Public Works 1.2 Summer Creek- Waterway Approximately 0.068 acres (2965.25 Sq. Ft.) of Summer Creek, below the ordinary high water mark(OHWM), in the waterway,will be impacted with the installation of extended culvert wing walls, riprap stone, washed stone, root wads, and macrophyte plants. Because this work occurs below the OHWM, it is not subject to the requested Comprehensive Plan Map Amendment and Economic, Social, Environmental, and Energy (ESEE) analysis. This information is included here for the reader's situational awareness of the overall project's full scope. 1.3 North Bank— Vegetated Corridor Approximately 0.020 acres (884.49 Sq. Ft.) of vegetated corridor on the north side of Summer Creek will be impacted with the installation of riprap stone, geocells, trees, and riparian plants; and the replacement of a broken stormwater line (from the roadway) with a new one. Invasive species in this area will be removed. The vegetated corridor will be enhanced and re-established with native species once work is completed. All replanting will be done to the specifications required by Clean Water Services. 1.4 Construction Related Impacts (Temporary) Temporary, construction related, impacts will occur on the west side of the SW 12l Avenue Bridge, in the waterway, for re-routing water during in-water work periods from July to September. These impacts will be mitigated through the use of best practices promulgated by Clean Water Services (CWS), Oregon Department of State Lands (DSL), and the Oregon Department of Environmental Quality (DEQ). Throughout the project area, it is estimated that approximately 97 native trees, 1,226 native shrubs,and 100 native wetland plants(sedges,rushes, grasses)will be planted once construction is completed. This restoration will replace the invasive plants and shrubs that are removed as part of this project,and the eight trees that will be removed on the north bank. 2. KEY FINDINGS The ESEE analysis that follows demonstrates that the positive economic, social, environmental, and energy outcomes of removing the Statewide Planning Goal 5 protections from the subject 0.010 acres of wetlands on the south creek bank and the 0.020 acres of vegetated corridor on the north bank outweigh maintaining the status quo protections for these areas and not allowing the bridge and bank stabilization work to occur.

The property owners at 11740 SW 121st Avenue contacted the City Tigard, concerned with the erosion that they were witnessing(over the course of years)on the south side of their property,where it borders Summer Creek. The City of Tigard Department of Public Works investigated and found the driveway at 11740 SW 121St Avenue to be at risk. Erosion of the creek bank was exposing the driveway retaining wall foundation. Both creekbanks (north and south) were witnessed to be severely eroded. As a result,the City included this project with its adopted Capital Improvement Project Budget FY2025-2026 (Stormwater Capital Improvement Plan #94057), with the goal of providing bank stabilization and mitigating the erosion. In 2025, the City contracted with WSP USA, Inc. (WSP) to conduct due diligence, including a wetland delineation, in the vicinity of the SW 121st Avenue Bridge. As part of the due diligence process,WSP found additional, significant, concerns. First,the erosion, caused by high volume, high velocity stormwater flows,was not limited to the creek banks. Eddies form near the bridge culvert wingwalls during high flow events and cause the road guardrail foundations to become exposed. The earth surrounding the road guardrail concrete footers was eroding away with each stormwater event. In addition, WSP found that the stormwater outfall, leading from SW 121st Avenue down from the roadway into Summer Creek, was broken, leading to water infiltrating behind the retaining wall supporting the driveway at 11740 SW 121st Avenue. In order to address these challenges, the following nine work items described in Section 3.3, 3.4, and 3.5 are being proposed as a part of this project. 3.2 Project Description There are nine work items proposed by the City of Tigard Department of Public Works Engineering Division. Each of these work items were carefully designed and vetted to (1) mitigate the adverse effects of erosion in the vicinity of the east side of the SW 121' Avenue Bridge and (2) enhance the environmental conditions of the area once work is completed (i.e. leave it in better environmental condition than it was found in). All of the proposed work will be completed in full accordance with the Clean Water Services (CWS) Design and Construction Standards, and the requirements specified by the Oregon Department of State Lands (DSL),the Oregon Department of Environmental Quality (DEQ), and the U.S. Army Corps of Engineers (USACE). 3.3 South Bank— Wetlands—0.010 acres (445.95 Sq. Ft.) 1. Shoring of the road guardrail foundations on the SW 121' Bridge. Replacement of the deteriorated road guardrails as required. 2. Installation of riprap stones and geocells in and around the exposed sanitary sewer manholes. • Tigard Public Works 3. Replanting of native wetlands plants and establishment of geocell vegetated upper slope. 3.4 Summer Creek— Waterway—0.068 acres (2965.25 Sq. Ft.)* 4. Extension of the existing concrete wingwall on the south side by seven feet. Extension of the existing concrete wingwall on the north side by six feet. 5. Cleaning of both the south and north bridge culverts of all sediment and debris. 6. Placement of native stone riffle breaks in the waterway. Root wads (six feet diameter) placed downstream. Macrophytes established as required(CWS, DSL,DEQ,USACE). *Because this work occurs below the OHWM, it is not subject to the requested Comprehensive Plan Map Amendment and Economic, Social, Environmental, and Energy(ESEE) analysis. This information is included here for the reader's situational awareness of the overall project's full scope. 3.5 North Bank— Vegetated Corridor—0.020 acres (884.49 Sq. Ft.) 7. Replacement broken stormwater line(from roadway)and outfall with new. Reposition to ensure that stormwater flows are directed away from the wing wall. 8. Secure north bank with riprap stones. 9. Establish geocell vegetated upper slope. Six trees on the north creek bank will be removed as a part of this project. In addition,all invasive species within the project area are to be removed. Approximately 97 native trees, 1,226 native shrubs,and 100 native wetland plants(sedges,rushes,grasses)will be planted once construction is completed. All replanting will be done to Clean Water Services' standards. • Tigard Public Works HIj &4 p W , I Q o b I. rc f Yp!

ECONOMIC,SOCIAL,ENVIRONMENTAL,AND ENERGY(ESEE)ANALYSIS A portion of the proposed project is located in area delineated on the City of Tigard Wetlands and Steam Corridors Map (September 2025) as a Significant Wetland and another portion of the proposed project area is a designated vegetated corridor.3 These designations were afforded to these areas pursuant to Statewide Planning Goal 5: Natural Resources, Scenic &Historic Areas, and Open Spaces (Statewide Planning Goal 5). Because the proposed work impacts a designated wetland and vegetated corridor, it represents a conflicting use and, as such, the applicant, in this instance the City of Tigard Department Public Works, Engineering Division, is seeking to remove the protections from the 0.010 acres (445.95 Sq.Ft.)of wetlands and the 0.020 acres(884.49 Sq. Ft.)of vegetated corridor through the completion of an economic, social, environmental,and energy(ESEE)analysis. Completion of an ESEE analysis is one of two ways specified in the City of Tigard Municipal Code to achieve the Comprehensive Plan Map Amendment required to address the conflicting use described above.The other avenue being a demonstration of change,which would require the applicant to provide evidence as to why delineated wetlands and vegetated corridor no longer meet the significance criteria in Statewide Planning Goal 5, when considered relative to similar environmental resources in the City of Tigard.4 With regard to the demonstration of change,the City of Tigard Department of Public Works, Engineering Division makes no such assertion and opts instead to complete the ESEE analysis based on the specific development proposal described above. The State of Oregon developed the ESEE process to assist local governments with implementing Statewide Planning Goal 5: Natural Resources, Scenic & Historic Areas, and Open Spaces. Oregon Administrative Rules (OAR) §660-023-0040 ESEE Decision Process requires that local governments complete following steps (not required to be completed in numerical order)when completing the ESEE process:5 1. Identify Conflicting Land Uses; 2. Determine the Impact Area; 3. Analyze the ESEE Consequences; and 4. Develop a Program to Achieve Goal 5. These steps are examined in detail in the analysis the follows, which will weigh the positives and negatives consequences associated with allowance of, or denial of, the proposed Comprehensive Plan Map Amendment. In this instance, the conflicting use described above, which would remove map protections for the 0.010 acres (445.95 Sq. Ft.)of wetlands and 0.020 acres (884.49 Sq. Ft.)of vegetated corridor, and allow for bridge and bank stabilization work to occur. 3 City of Tigard,Oregon, Wetlands&Stream Corridors: City of Tigard, Oregon,accessed 24Mar2026.Link.

To identify these uses, local governments shall examine land uses allowed outright or conditionally within the zones applied to the resource site and in its impact area. Local governments are not required to consider allowed uses that would be unlikely to occur in the impact area because existing permanent uses occupy the site. The following shall also apply in the identification of conflicting uses: (a) If no uses conflict with a significant resource site, acknowledged policies and land use regulations may be considered sufficient to protect the resource site. The determination that there are no conflicting uses must be based on the applicable zoning rather than ownership of the site. (Therefore, public ownership of a site does not by itself support a conclusion that there are no conflicting uses). (b) A local government may determine that one or more significant Goal 5 resource sites are conflicting uses with another significant resource site. The local government shall determine the level of protection for each significant site using the ESEE process and/or the requirements in OAR 660-023-0090 through 660- 023-0230(see 660-023-0020(1)). RESPONSE The entire project area is publicly owned, and the City is not proposing a change in the site's underlying zone (Parks and Recreation District), nor a deviation from the site's current use. However,the City is proposing a change to two areas within the site that are currently delineated on the City of Tigard Wetlands and Steam Corridor Map. The City is seeking to remove protections from the 0.010 acres(445.95 Sq.Ft.)of wetlands and the 0.020 acres(884.49 Sq.Ft.) of vegetated corridor. These changes will be permanent in that they will remove protection from these two areas (i.e. they will be removed from the City of Tigard Wetlands and Stream Corridor Map through a Comprehensive Plan Map Amendment). As such, it is this aspect of the City's proposal that presents the Conflicting Use. The City is making this request in order to provide permanent stabilization to the eroding creek banks and the SW 121 st Avenue Bridge, and to fix a broken stormwater outfall leading from SW 121'Avenue to the creek. This proposed action requires a ESEE analysis to be completed. This ESEE analysis will weigh the positives and negative consequences associated with allowance of,or denial of,the proposed Comprehensive Plan Map Amendment and applies only to those areas described above. THIS ESEE STEP IS MET. e •T igard Public Works 4.2 Determine the Impact Area (OAR§660-023-0040.3) (3) Determine the impact area. Local governments shall determine an impact area for each significant resource site. The impact area shall be drawn to include only the area in which allowed uses could adversely affect the identified resource. The impact area defines the geographic limits within which to conduct an ESEE analysis for the identified significant resource site. RESPONSE The work impact areas are described below. Of note, two of the work items (#2 and #4) are in Summer Creek, meaning that they are below ordinary high water mark(OHWM) and are in the waterway. As such, they are not mapped, unlike #1 and#3, which are both mapped on the City of Tigard Wetlands and Steam Corridors Map(September 2025), as a locally significant wetland and a designated vegetated corridor, respectively. For this Comprehensive Plan Map Amendment, the City requests that the mapped Goal 5 protections for work items #1 and#3 be removed to allow for the bank and bridge stabilization work to occur. (1)Approximately 0.010 acres (445.95 Sq. Ft.)of wetlands on the south side of Summer Creek will be impacted by the proposed work. The proposed work, impacting these wetlands, includes the shoring of the road guardrail foundations on the SW 121 st Bridge,the extension of the existing concrete wingwall by seven feet, the installation of riprap stones and geocells in and around the exposed sanitary sewer manholes, and the replanting of wetlands plants. (2)Approximately 0.068 acres(2965.25 Sq.Ft.)of Summer Creek,below the ordinary high water mark (OHWM), will be impacted with the installation of extended culvert wing walls, riprap stone, washed stone for riffle breaks, root wads, and macrophyte plants. (3)Approximately 0.020 acres(884.49 Sq.Ft.)of vegetated corridor on the north side of Summer Creek will be impacted with the installation of riprap stone, geocells, trees, and riparian plants; and the replacement of a broken stormwater line(from the roadway)with a new one. (4)Temporary,construction related,impacts will occur on the west side of the SW 121 st Avenue Bridge, in the waterway, for re-routing water during in-water work periods from July to September and throughout the project area which is delineated in Figure 1: Proposed Project Site Plan.

Local governments shall analyze the ESEE consequences that could result from decisions to allow, limit, or prohibit a conflicting use. The analysis may address each of the identified conflicting uses, or it may address a group of similar conflicting uses. A local government may conduct a single analysis for two or more resource sites that are within the same area or that are similarly situated and subject to the same zoning. The local government may establish a matrix of commonly occurring conflicting uses and apply the matrix to particular resource sites in order to facilitate the analysis. A local government may conduct a single analysis for a site containing more than one significant Goal 5 resource. The ESEE analysis must consider any applicable statewide goal or acknowledged plan requirements, including the requirements of Goal 5. The analyses of the ESEE consequences shall be adopted either as part of the plan or as a land use regulation. RESPONSE For this component of the ESEE analysis,positive and negative consequences are examined for the ECONOMIC, SOCIAL, ENVIRONMENTAL, and ENERGY categories under the following two scenarios: 1. Maintaining the Goal 5 protections for the 0.010 acres of wetlands on the south side of Summer Creek and the 0.020 acres of vegetated corridor on the north side of Summer Creek, which would not allow the proposed bridge and bank stabilization work to occur and would not allow for a conflicting use to occur. 2. Removal of the Goal 5 protections for the 0.010 acres of wetlands on the south side of Summer Creek and the 0.020 acres of vegetated corridor from the north side of Summer Creek, which would allow the proposed bridge and bank stabilization work to occur and would allow for a conflicting use to occur. ECONOMIC Scenario 1:Maintaining Goal 5 Protections Negative Economic Consequences • The primary negative economic consequences of maintaining the existing Goal 5 protections involve liability. Specifically, the City's liability should a northbound motor vehicle on the SW 121st Avenue Bridge hit the guardrail, with a foundation known to be compromised due to erosion, and suffer a catastrophic crash in or around Summer Creek. • Additional negative economic consequences of maintaining the existing Goal 5 protections also involve liability and specifically pertain to the private property at 11740 SW 1215t Avenue. A broken stormwater outfall and erosion are compromising the eCITY OF Ti gard Public Works driveway foundation at 11740 SW 1215t Avenue. The driveway itself, and any motor vehicles parked on it, are at risk should the driveway collapse into the north creek bank. • A final negative economic consequence of maintaining the existing Goal 5 protections involves the high costs associated with deferred maintenance for the broken stormwater outfall on the north creek bank and the exposed sanitary sewer manholes on the south creek bank. Eventually, if maintenance continues to be deferred and erosion is allowed to continue unmitigated, there will be a system failure involving one, if not both, of these critical utilities. Failure of the sanitary sewer line would result in a DEQ illicit discharge, which would require immediate action. Repair costs at such a time will be considerably higher than they are today. Positive Economic Consequences • Positive economic consequences of maintaining the existing Goal 5 protections are primarily short-term in that the City would not spend the money currently budgeted to perform the bridge and bank stabilization, and wetland and vegetated corridor enhancement($840,000). Scenario 2:Removing Goal 5 Protections Negative Economic Consequences • In the short-term,removing the Goal 5 protections for the subject wetlands and vegetated corridor, which would allow for the bridge and bank stabilization, wetland and vegetated corridor enhancement to occur,will cost the City the money it has budgeted for the project ($840,000). Positive Economic Consequences • One of the primary positive economic consequences of removing the Goal 5 protections for the subject wetlands and vegetated corridor,which would allow for the bridge and bank stabilization, wetland and vegetated corridor enhancement to occur, will decrease the City's liability in the event of motor vehicle crash impacting the guardrail on the northbound side of the SW 1215` Avenue Bridge. The compromised guardrail will be replaced, along with new—secured—concrete footers. • In addition, removing the Goal 5 protections for the subject wetlands and vegetated corridor, which would allow for the bridge and bank stabilization, wetland and vegetated corridor enhancement to occur,will decrease the City's liability for any damages incurred involving the private property at 11740 SW 1215t Avenue, specifically the driveway, and any motor vehicles park on it, and/or the fence and home,which are both proximate to the north creek bank. • Finally, removing the Goal 5 protections for the subject wetlands and vegetated corridor, which would allow for the bridge and bank stabilization, wetland and vegetated corridor . • Tigard Public Works enhancement to occur, will result in the replacement of the broken stormwater outfall leading from SW 121St Avenue to Summer Creek and the stabilization of the creek bank around the two sanitary sewer manholes on the south creek bank,protecting these critical utilities from further deterioration and preventing costly future repairs in the event of catastrophic utility failure. ECONOMIC—CONCLUSION The positive and negative economic impacts associated with both scenarios were analyzed above. In Scenario 1: Maintaining Goal 5 Protections, 3 negative consequences and 1 positive consequence were identified. In Scenario 2: Removing Goal 5 Protections, 1 negative consequence and 3 positive consequences were identified. In addition to the quantitative difference in outcomes,the qualitative differences(e.g.reduced liability)favor removing Goal 5 protections. On balance, Scenario 2: Removing Goal 5 Protections resulted in better economic outcomes. aTig'ard Public Works y., SOCIAL Scenario 1:Maintaining Goal 5 Protections Negative Social Consequences • The primary negative social consequence of maintaining the existing Goal 5 protections involves life safety. First, the guardrail on the northbound lane of the SW 121st Avenue Bridge has a concrete foundation that is currently being exposed by erosion. If a motor vehicle were to hit it, there is concern that the guardrail would fail and the driver and/or passenger would be seriously injured or killed. • An additional negative social consequence, related to life safety, of maintaining the existing Goal 5 protections pertains to the private property at 11740 SW 121' Avenue. The driveway foundation is being damaged due to erosion. The retaining wall supporting the driveway foundation and preventing it from sliding down the north creek bank is now less than 6"away from the drop-off(due to soil loss). The driveway,along with any adult or child walking on it, and any motor vehicle parked on it, are at risk for serious injury or death in the event of foundation collapse and a landslide into the creek. • There is a negative aesthetic consequence that result from maintaining the existing Goal 5 protections in that the erosive impacts from stormwater events will continue to go unabated resulting in further bank erosion, creek sedimentation,and plant, shrub, and tree loss. • Finally, an additional health risk would remain unmitigated if the existing Goal 5 protections are left in place. There are two sanitary sewer manholes on the south creek bank that are currently being repeatedly exposed to stormwater. The soil around these manholes is eroding away, leaving the manholes exposed. If left unaddressed (both of these manholes are in the subject wetlands), the City risks damage to the sanitary sewer line, which would present a health risk, as sanitary sewer functionality is a critical "no- fail"utility. Positive Social Consequences • There are no predicted positive social consequences that would come from maintaining the Goal 5 protections. Scenario 2:Removing Goal 5 Protections Negative Social Consequences • There are no predicted negative social consequences that would come from removing the Goal 5 protections. . • Tigard Public Works Positive Social Consequences ■ Removing the Goal 5 protections would allow for the guardrail on the northbound lane of the 121 st Avenue Bridge to be secured/replaced and for strengthened footers to be installed. This action would result in motorists being better protected in the event of a crash. • In addition,removing the Goal 5 protections will enable the City to perform the repairs on the north creek bank required to secure the bank and to reduce the risk of the driveway at 11740 SW 121' Avenue from catastrophically collapsing down the creek bank. The broken stormwater outfall would be replaced, and riprap stone and geocells will be installed to secure the creek bank. These actions would help mitigate the life safety risks that currently persist. • Aesthetic benefits would be realized through the removal of the Goal 5 protections. Both creek banks would be secured with riprap stone and geocells, and both will feature vegetated upper slopes. On the north creek bank root wads will be installed at the base of the riprap stone.On both creek banks,invasive plantings will be removed and,collectively, approximately 97 native trees, 1,226 native shrubs,and 100 native wetland plants(sedges, rushes, grasses) will be planted once construction is completed. These actions will help prevent further bank erosion, creek sedimentation, and plant, shrub, and tree loss. • Finally,public health would benefit from the removal of the Goal 5 protections. The two sanitary sewer manholes on the south creek bank would be secured with reinforced soil, riprap stone, and geocell. This would help prevent further erosion around them. SOCIAL—CONCLUSION The positive and negative social impacts associated with both scenarios were analyzed above. In Scenario 1: Maintaining Goal 5 Protections, 4 negative consequences and 0 positive consequence were identified. In Scenario 2: Removing Goal 5 Protections, 0 negative consequence and 4 positive consequences were identified. In addition to the quantitative difference in outcomes, the qualitative differences (e.g. life safety protections) favor removing Goal 5 protections. On balance,Scenario 2:Removing Goal 5 Protections resulted in better social outcomes. 0-Tigard Public Works • ENVIRONMENTAL Scenario 1:Maintaining Goal 5 Protections Negative Environmental Consequences ■ If the existing Goal 5 protections are maintained, the current environmental conditions will persist.Erosion will continue to pull earth,plants,shrubs,and trees off the creek banks and into Summer Creek during stormwater events. Sedimentation will continue unabated and turbid conditions will persist; water quality will continue to be degraded. ■ In addition, should the Goal 5 protections be maintained, invasive species will continue to dominate the creek banks. The June 2025 wetlands delineation determined that the herbaceous vegetation in the wetlands was "dominated by bird's-foot trefoil (Lotus corniculatus) and reed canarygrass (Phalaris arundinacea)."6 Both bird's foot trefoil and reed canarygrass are invasive species that outcompete natives, their predominance within the subject wetland area, highlight the wetlands' degraded condition. Positive Environmental Consequences • Maintaining the Goal 5 protections would prolong the life of the six trees on the north creek bank that are to be removed as part of the north bank stabilization component of the proposed project. These trees are valued environmental assets. Scenario 2:Removing Goal 5 Protections Negative Environmental Consequences • Removal of the Goal 5 protections for the for the 0.010 acres of wetlands on the south side of Summer Creek and the 0.020 acres of vegetated corridor from the north side of Summer Creek,would allow for the six trees on the north creek bank to be removed(required Tree Removal Permit would be obtained). Positive Environmental Consequences • If the Goal 5 protections are removed both the south (wetland) and north (vegetated corridor) creek banks will be stabilized and erosion will not have the impacts that it currently does during stormwater events. Riprap stone, with geocells underlay, and vegetated upper slopes will be installed on both the south and north creek banks. Native plants, shrubs, and trees will be planted. These plantings will be done to CWS standards, which are widely regarded as best practices. Sedimentation from soil loss will be minimized, turbidity, and water quality, will be improved. Plants, shrubs, and trees will maintain stability during stormwater events and will not be washed into Summer Creek. 6 Larsson,Ingrid and Feltus,Hallie, Wetland and Other Waters Delineation Report:Summer Creek Bank Stabilization Assessment and Design,WSP USA,Inc.,June 2025,Page 4. e,.Tigard • Public Works 1 ■ Furthermore, lifting of the Goal 5 protections will result in all the invasive plants, shrubs, and trees being removed from the subject wetlands (south bank) and subject vegetated corridor(north bank). • Removal of the Goal 5 protections will allow the project to move forward and will result in approximately 97 native trees, 1,226 native shrubs, and 100 native wetland plants (sedges,rushes, grasses)being planted once construction is completed. • Removing the Goal 5 protections will enable protection of the sanitary sewer manholes, which could prevent illicit discharges into the waterway. ENVIRONMENTAL—CONCLUSION The positive and negative environmental impacts associated with both scenarios were analyzed above. In Scenario 1: Maintaining Goal 5 Protections, 2 negative consequences and 1 positive consequence were identified. In Scenario 2: Removing Goal 5 Protections, 1 negative consequence and 4 positive consequences were identified. In addition to the quantitative difference in outcomes, the qualitative differences (e.g. restoration with native species) favor removing Goal 5 protections. On balance,Scenario 2:Removing Goal 5 Protections resulted in better environmental outcomes. Tigard Public Works ENERGY Scenario 1:Maintaining Goal 5 Protections Negative Energy Consequences ■ Maintaining the Goal 5 protections for the subject wetland the subject vegetated corridor could result in a motor vehicle crashing through the existing deteriorated guardrail and going into Summer Creek and/or a motor vehicle sliding down the north creek bank into Summer Creek, should the driveway at 11740 SW 121' Avenue collapse. In either instance, this would result in heavy machinery, powered by an internal combustion engine(s),being dispatched to retrieve the motor vehicle from the creek. Such an operation would likely require the temporary closure of the SW 121 St Avenue Bridge,which would impact motorist who use the bridge and could lead to more vehicle miles travelled(VMT). Positive Energy Consequences • If the existing Goal 5 protections are maintained, there will be no temporary construction related impacts to vehicular travel on the SW 121st Bridge.This could mean that motorists will not increase their respective VMT when the bridge is restricted to one travel lane (it is currently two)during work hours. Scenario 2: Removing Goal 5 Protections Negative Energy Consequences • In the short-term, removing the Goal 5 protections for the subject wetlands and vegetated corridor, which would allow for the bridge and bank stabilization, wetland and vegetated corridor enhancement to occur, would result in temporary construction related impacts. The SW 121' Bridge would be restricted to one travel lane (it is currently two) during work hours.This would impact motorists who use the bridge and could lead to more VMT. Positive Energy Consequences • Removing the Goal 5 protections for the subject wetland and the subject vegetated corridor would allow for the guardrail on the northbound lane of the SW 121st Avenue Bridge to be secured/replaced and for strengthened footers to be installed. It would also allow for the north creek bank to be stabilized and the broken stormwater outfall to be replaced, which would better protect the driveway at 11740 SW 121st Avenue. These actions would result in motorists being better protected in the event of a crash and would likely prevent vehicles from entering Summer Creek in the event of a crash(or driveway collapse),which eliminates the need for heavy machinery,powered by an internal combustion engine(s),to remove vehicles from the creek. • Tigar d Td Public Works ENERGY—CONCLUSION The positive and negative economic impacts associated with both scenarios were analyzed above. In Scenario 1: Maintaining Goal 5 Protections, 1 negative consequences and 1 positive consequence were identified. In Scenario 2: Removing Goal 5 Protections, 1 negative consequence and 1 positive consequences were identified. In this instance, there was no quantitative difference in outcomes, the qualitative differences (e.g. vehicle entering Summer Creek in the event of a crash or driveway collapse) favor removing Goal 5 protections. On balance,Scenario 2:Removing Goal 5 Protections resulted in better energy outcomes ESEE ANALYSIS SUMMARY This ESEE analysis found that, in this instance,the removal of the Goal 5 protections for the for the 0.010 acres of wetlands on the south side of Summer Creek and the 0.020 acres of vegetated corridor from the north side of Summer Creek is warranted because of the positive economic, social, environmental, and energy outcomes of allowing the bridge and bank stabilization work to occur significantly outweigh the risks and consequence of not allowing the bridge and bank stabilization work to occur both quantitatively and qualitatively. THIS ESEE STEP IS MET. aTigard ' Public Works 4.4 Develop a Program to Achieve Goal 5 (OAR§660-023-0040.5) (5) Develop a program to achieve Goal 5. Local governments shall determine whether to allow, limit, or prohibit identified conflicting uses for significant resource sites. This decision shall be based upon and supported by the ESEE analysis. A decision to prohibit or limit conflicting uses protects a resource site.A decision to allow some or all conflicting uses for a particular site may also be consistent with Goal 5, provided it is supported by the ESEE analysis. One of the following determinations shall be reached with regard to conflicting uses for a significant resource site: (a) A local government may decide that a significant resource site is of such importance compared to the conflicting uses, and the ESEE consequences of allowing the conflicting uses are so detrimental to the resource, that the conflicting uses should be prohibited. (b) A local government may decide that both the resource site and the conflicting uses are important compared to each other, and, based on the ESEE analysis, the conflicting uses should be allowed in a limited way that protects the resource site to a desired extent. (c) A local government may decide that the conflicting use should be allowed fully, notwithstanding the possible impacts on the resource site. The ESEE analysis must demonstrate that the conflicting use is of sufficient importance relative to the resource site, and must indicate why measures to protect the resource to some extent should not be provided, as per subsection (b) of this section. RESPONSE The applicant carefully considered the proposed work through the completion of the ESEE analysis.Any time protections are permanently removed from wetlands and/or vegetated corridor it should create a moment of pause. In this instance,the applicant—the City of Tigard Department of Public Work Engineering Division—efforted to design the project in a way that resulted in the minimal amount of protections being removed (0.010 acres/445.95 Sq. Ft. and 0.020 acres/884.49 Sq. Ft., respectively), while ensuring the bridge and bank stabilization work could still successfully occur and the environmental enhancement work could be maximized. In this instance,impacts will be mitigated through the use of best practices promulgated by Clean Water Services(CWS), Oregon Department of State Lands (DSL), and the Oregon Department of Environmental Quality(DEQ). Once work is completed,the impacted wetland will be restored with native plant species,and the impacted vegetated corridor will be restored with native plants, shrubs, and trees. In simple terms,the subject wetland and the subject vegetated corridor will be left better than they were found because of this project. In conclusion, after careful consideration, the applicant respectfully proposes that the City of Tigard allow for the conflicting use,in accordance with OAR§660-023-0040.5.C(listed above). gm.
