This letter is to inform you that additional materials will be needed in oxdex to deem your application complete. The necessary materials are as follows: 1. Sensitive Lands Review (SLR�. A sensitive lands review may be required for work withul the wetland vegetated corridor because the Tigard wedand regulations apply to both the wedand and vegetated corridor (per 18.775.050. Could the new wetland and wedand corridor be labeled on the plans to show that work is outside of the wedands and only in the vegetated corridor? If wedands sensitive lands review is required, please submit that application fee at half the cost ($2,428 x .5 = $1,214). 2. Narrative. Please provide a revised narrative that addresses the following: • Is woxk being done within the vegetated corridor of Fanno Creek? If yes, then please address section 18.775.090.B.

I am assuming because this is a restoration project and because it is assumed that the wetlands affected by the new meander, would be replaced the filling of the old channel (i.e., farmer wetland become stream and former stream become wetland). On the east side of the channel, i would not expect the ultimate wetiand boundary to change from what it is today. In summary, the current boundary(i.e., perimeter} should be the future boundary. Where the pond is going is currentEy a wetland/stormwater treatment facility and upland. To the best of my knowiedge, Clean Water Services was not required to identify the extent of wetiand�s. open water created-the pond design as a whole was submitted. I suggested to Ben that if the City needs a "boundary"to use the 2 year water surface elevation. The pond was designed to detain/retain water up to this elevation. If you need some additional information , please let me know and I will do my best to address it on Friday.

Included are redlines to the narrative and plans. The biggest question we have is with regards to the new wetlands to be created with the CWS Remeander. It seems like CWS should have received a permit from DSL/COE for wetland mitigation. I am guessing that the planting shown on Sheet L3.0 should be a reflection of the mitigation. I have requested the DSL/COE permit from CWS, but I have not received anything yet. We need to resolve this issue prior to resubmitting for completeness.

The recreational and commuter trail will connect the Willamette River in Southwest Portland to the confluence of Fanno Creek and the Tualatin River. Phase One Improvements of Lower Fanno Creek Park includes reconstructed bike and pedestrian trails, two bridges,and landscaping within the limits of the Clean Water Services(CWS)Re-Meander project in Lower Fanno Creek Park in downtown Tigard. This project submittal does not include the Re-Meander and restoration work by CWS. This project only includes the trails,bridges and landscaping within the limits of and in response to the Re-Meander. The description below is provided for reference. CWS Proiect Description(FOR REFERENCE ONLY) The CWS Re-Meander is a stream and wetland enhancement project along Fanno Creek with the intent to restore habitat and improve water quality in the Tualatin River Basin. Past land use activities straightened a portion of Fanno Creek in the project area. The CWS project is an aTtempt to remedy this straightening by creating a large meander to lengthen the channel, reducing the sfope and slowing the water down. Questions about the Re-Meander project should be directed to Clean Water Services(Rich Hunter at(503) 681-3638 HunterR@cleanwaterservices.or�). Existing trails and a bridge will be removed by the CWS work.Therefore,this requires the City and CWS to work together to replace the trails and bridge and to enhance the park in Phase One to meet the goals of the 2008 Master Plan for Fanno Creek Park and Plaza. The site improvements for Phase One include: • Replacing the Ash Avenue Bridge with a steel truss pedestrian bridge and raising the bridge deck to clear the 2-year flood elevation so it does not obstruct the creek flow and collect debris during annual rain events. • Replacing the pedestrian and bike trail to be removed during the CWS Re-Meander project. All new trails will be rebuilt to meet ADA accessibility standards. • Providing an enhanced trailhead at the end of Ash Avenue which includes pavers,seatwalls,a park entry sign,and native plantings. Page� 1 � T • Planting and seeding along the edges of the trail to create a safety corridor,and to blend with native plant habitats proposed for the park as outlined in the 2008 Master Plan. In the plan,a 10 foot wide asphalt trail is proposed for pedestrian and bicyc�e users,to serve as the regional multi-modal Fanno Creek Greenway.The regional trail runs through the park from Hall Boulevard to Ash Avenue. At Ash Avenue,this trail crosses the Ash Avenue pedestrian bridge,and heads north along the CWS high-water area on the west side of Fanno Creek connecting to the existing regional trail. As shown in the 2008 Master Plan for Fanno Creek Park,the future regional trail runs north on the east side of Fanno Creek between Ash Avenue and Main Street to connect to a future public plaza. For the Phase One improvements,the trail extending to the Ash Avenue trailhead is proposed to be 10 feet wide to meet the standards of the future trail alignment. The current regional trail on the east side of Fanno creek, north of Ash Avenue,will be a secondary trail in the future and therefore is proposed to be only 8' wide for the Phase One Improvements. Trail Width and Cross Sections The width of the trail should be the minimum necessary to serve the intended use,but should not be so narrow that it compromises the safety of the users.The Fanno Creek Greenway Trail Action Plan recommends typical cross sections for its multi-modal trail. It calls for a trail width of 8 to 12 feet,with a 2 foot gravel shoulder on either side,making a total corridor of 12 to 16 feet.It requires a vertical clear zone of 8 to 10 feet.For this park,we recommend a trail width of 10 feet with 12"gravel shoulders,for a total corridor of 12 feet.The secondary trails,inctuding the trail section through the high water area,will be 8 feet wide with 12"gravel shoulders. Trail Safety Corridors Fanno Creek Park is a known location for indiscriminate uses,and a major priority for current park users is that the trail be designed to increase user safety.With this need in mind,the 2008 Master Plan proposes that the vegetation on either side of the trail be managed to allow clear sight lines within the region of the trail.The landscape design and management technique would maintain a naturalistic look,and would enhance the overall aesthetic of the park by allowing for a greater variety of views. For the wider regional trail,there should be no trees within 5 feet of the shoulder of the trail,and no shrubs within 10 feet.The vegetation in this area should be a naturalized rough meadow,and kept clear of shrubs through annual mowing. For the more narrow 6 to 8 foot secondary trails,there should be a 5 foot zone clear of trees or shrubs,with the natural condition allowed to continue outside of the 5 foot zone. Project Impacts The project will replace and improve existing trails and the Ash Avenue pedestrian bridge. The trails are being redeveloped to meet ADA guidelines. The Ash Avenue Bridge will be replaced and raised to improve hydrology, park maintenance, and reduce erosion. Restoration planting will improve wildlife habitat. Restoration planting will be performed by CWS within the project limits. Impacts from construction activities will include the following: • Temporary closure of the park within the construction limits shown on the plans. • Closure of the bike and pedestrian trails within the limits shown on the plans. • Construction trucks and equipment will use Ash Avenue south and stage within the construction limits of the project as shown on the Demolition Plan—Sheet LD1.0. Construction equipment will include: o Standard earth moving machinery to sculpt the paths to meet the desired grade. o Standard trucks and machinery to transport and lay base rock and asphalt for the paths and trailhead improvements. o Standard trucks and machinery to transport and construct concrete for the bridge abutments. o Standard trucks and cranes to transport and place prefabricated bridge in place. o Construction staging and parking in designated areas—see Demolition Plan LD.O. • No Pub►ic Utilities will be impacted by this project.

Project Narrative The following Project Narrative describes compliance with applicable sections of Title 18: Community Development Code and approval criteria as specified in the Pre-Application Conference Notes. 18.390 Decision Making Procedures/Impact Study This project is within Sensitive Lands and within the 100-year Floodplain and therefore requires a Type III procedure. This application is for Sensitive Lands Review(18.775)to be decided by the Hearings Officer with appeals of the decision going to the City Council. Impact Study The city improvements will not create impacts beyond the limits of work shown in the drawings. The impacts the project will incur include a temporary closure of Fanno Creek Park and Greenway within the work limits. The temporary closure will affect bicycle and pedestrian traffic from Main St.to Ash Ave.The water system,drainage system,and sewer system will not be impacted by the improvements.The City improvements are enhancements to Fanno Creek Park and Greenway. 18.39Q.050 Type III Procedure A.

The following base flood data is taken from Figure 3 of the Hydraulics Report: • Glulam Bridge spanning the stormwater channel (see Sheet 51.1): o Existing Base Flood Elevation=148.54 o Proposed Base Flood Elevation=148.31 • Ash Avenue Bridge spanning Fanno Creek(See Sheet 51.2) o Existing Base Flood Elevation=148.00 o Proposed Base Flood Elevation=147.99 E. Resistant to flood dama�e All new construction and substantial improvements,including the trails and bridges,are proposed to be constructed with materials and utility equipment resistant to flood damage. Seasonal maintenance of the park will be required by the City after flood events,which would include the removal of debris from the trails and bridges. The Glulam Bridge will be prefabricated and made of pressure treated lumber structural members and decking with stainless steel cables guardrails(See Sheet 51.1). The Ash Avenue Bridge will be prefabricated and made of weathered steel structural members and cast-in-place concrete decking(See Sheet 51.2). The abutments for both bridges will be cast-in-place concrete. F. Minimize flood damase The City Improvements and construction methods and practices will minimize flood damage.The placement of the abutments back from the ordinary high water mark and the placement of the bridge chord at a higher elevation will minimize flood damage. Proper erosion control,revegetation and compaction around the abutments will also minimize flood damage. I. Anchorin� New bridges will be anchored to concrete abutments sized to prevent lateral movement or failure during flood events. Ash Creek Geotechnical Engineers provided geotechnical investigation and parameters for sizing the bridge abutments. KPFF Structural Engineers worked with Contech Bridge Company(70'steel truss bridge)and Western Wood Structures(30'wood bridge)to adequately design the pre-fabricated bridge and size anchoring members based on Fanno Creek velocities during flood events. The details for the bridges and abutments are included in this submittal—Sheets S1,S2,and S3. The structural designs for the bridges are based on the requirements of the 2007 Oregon Structural Specialty Code as well as the requirements of the Tigard Municipal Code for Anchorage and Buoyancy. The Geotechnical report by Ash Creek Geotechnical Engineers and Structural Memo by KPFF Structural Engineers are also included in this Page�4 submittal. Structural calculations will be provided to the City Building Department for review and approval prior to issuance of the Building Permit. M. Non-Residential construction See notes above responding to 18.775.040(I)Anchoring. 18.775.050 General Provisions for Wetlands The CWS Re-Meander project has obtained ACOE and DSL permits for impacts to wetlands. CWS is performing wetland mitigation and enhancements as part of the Re-Meander project. Existing and proposed wetland boundaries are shown on the plans for reference. Pacific Habitat Services addressed mitigation in the submittal to CWS to obtain the Service Provider Letter. The City improvements wilf be outside of the limits of the reestablished wetlands. 18.775.070 Sensitive Land Permits This submittal is applying for a Sensitive Lands Permit Type III per 18.775.020.G. Because it is within the 100-year floodplain,the application will be reviewed and approved by a hearings officer. B. Within the 100-vear floodplain 1. The land form alterations—proposed grades—within the 100-year floodplain sha►I preserve the floodplain storage. A"No-Rise" letter and report by HDR is included in this submittal. The grade changes proposed for this project improves ADA accessibility and stream flow. The grading to the trails will be modified to be 5%or less. The two bridges will be elevated so that the bottom of the bridge is above the 2 year flood elevation to enhance stream hydrology,and reduce erosion and maintenance. 2. The City improvements in Fanno Creek Park are for the purpose of community recreation and therefore land form alterations within the 100-year floodplain are allowed. 3. The land form alterations shall preserve the water surface elevation of the 100-year flood. A "No-Rise"letter and report by HDR is included in this submittal. 4. The proposed trails within this project are part of the Fanno Creek Regional Greenway and the 2008 Fanno Creek Park Master Plan which was approved and adopted by Tigard City Council. 5. A Wildlife Habitat Assessment by Pacific Habitat Ser�ices is included in this submittal. 6. CWS has obtained necessary U.S.Army Corps of Engineers and Department of State Lands permits for the Re-Meander project. The City improvements will be outside of the limits of the reestablished wetlands and ordinary high water of Fanno Creek and therefore do not require additional permits from these agencies. A CWS permit(Service Provider Letter)has been obtained for the City improvements and is included in this submittal. 7. The proposed trails within this project are part of the Fanno Creek Regional Greenway and the 2008 Fanno Creek Park Master Plan,which are in accordance with the adopted pedestrian/bicycle pathway plan. C. Within steep slopes This application does not propose work on slopes of 25%or greater or on unstable ground. D. Within draina�e wavs Fanno Creek and the Stormwater Channel coming from the east are considered drainage ways. There will be no impact to the drainage ways by the City construction improvements. E. Within wetlands 1. As noted above,CWS has obtained necessary U.S.Army Corps of Engineers and Department of State Lands permits for the Re-Meander project. The City improvements will be outside of the limits of the reestablished wetlands and ordinary high water of Fanno Creek and therefore do not require additional permits from these agencies. City improvements are located within the Vegetated Corridor. Mitigation and enhancements are proposed for the impacts per CWS requirements. A CWS Service Provider letter has been obtained for the City improvements and is included in this submittal. The proposed trails are within the Vegetated Corridor and therefore Page� 5 � . we have provided a mitigation plan which has been approved by CWS—see figures A, B,and C within the CWS SPL Material. 2. The project landform alterations for the City improvements are minimal. The intent of the landform alterations are such that the trail is on grade but rises to the trailhead at Ash Avenue and the Ash Avenue Bridge to span Fanno Creek. The resultant slopes for the trail are ADA accessible. See Fine Grading Plan: L2.0. 3. The City improvements do not impact on-site or offsite drainage. 4. Ail disturbed areas will be restored. See Pianting Plan: L3.0. 5. This submittal packet addresses tne applicable sensitive lands requirements outlined in the Sensitive Lands Code 18.775. 6. As noted above,CWS has obtained necessary U.S.Army Corps of Engineers and Department of State Lands permits for the Re-Meander project. The City improvements wifl be outside of the limits of delineated wetlands and the ordinary high water of Fanno Creek and therefore does not require additional permits from these agencies. 7. The provisions of Chapter 18.790 are addressed. See below. 8. For the City improvements, physical limitations and natural hazards,floodplains and wetlands, natural areas, and parks recreation and open space policies of the comprehensive plan have been satisfied. 18.775.080 Application Submission Requirements The following is included in this submittal: Sensitive Lands Application Documents • Sensitive Lands Application Form • Pre-Application Meeting Notes • Tax Lot Map CWS Service Provider pocuments • CWS Service Provider Letter • CWS Stamped Approved Plans and Figures(4) Plans CWS PLANS: FOR REFERENCE ONLY • Existing Conditions Plans: EX1.0 • CWS Re-Meander Plan: EX2.0 • Erosion Control Plans: E-01—E-04 CITY 1MPROVEMENT PLANS: BY APPLICANT • Demolition Plan: LD1.0 • Limit of Work: L0.0 • Site Plans: L1.0 and L1.1 • Grading Plan: L2.0 • Landscape Plans: L3.0 and L3.1 • Site Details: L4.0 and L4.1 • StructuralPlans: S1—S3 Reports • Arborist Tree Plan and Report • Habitat Assessment • Geotechnical Report • Hydraulics Report Memos • No-Rise Certification • Structural Memo Page� 6 Y • Stormwater Filtration Memo Neighborhood Meetin�Documents • Neighborhood Meeting Affidavit • Neighborhood Meeting Sign In Sheet • Neighborhood Meeting Notes 18.775.090 Special Provisions for Development along Fanno Creek A. Wetlands mitigation and enhancements are not part of this project. As noted above,the CWS Re- meander project has addressed this and obtained Amy Corps and DSL permit. B. Vegetated Corridor requirements are set by CWS. The SPL is included in this submittal demonstrating adherence to these parameters. The standard width of vegetated corridors along Fanno Creek is 50 feet.Wetlands within the standard setback are locally significant and therefore the vegetated corridor extends an additional 50 feet from the edge of wetlands,where present.As explained in section 18.775.040.B.5,ihe standard vegetated corridor width applies to all development within or partially within the vegetated corridors,except where specific exceptions are allowed.Proposed trail sections fall within several of the allowed exceptions.These sections include 18.775.090.8.5.subsections a,c,e,and g. All proposed trail sections are either 8 or 10 feet wide(plus shoulders)and meet CWS Design and Construction Standards,which are allowed exceptions under Section 18.775.090.6.5.c. Proposed sections have been designed to limit impacts to the vegetated corridor to the extent practicable.The new alignment west of the Fanno Creek remeander will impact"degraded condition"vegetated corridor near its intersection with the existing east west regional trail,cross sensitive areas west of Fanno Creek,and then cross a narrow strip of"good condition"vegetated corridor between the wetland and the existing trail before aligning with the existing trail.These impacts are allowed per Section 18.775.090.6.5.a. Impacts to vegetated corridor in the immediate vicinity of the new bridge,and the trail realignment to the east,are allowed under Section 18.775.090.6.5.g;because the bridge is a replacement of an existing structure and associated impacts to"marginal and degraded condition"plant communities do not encroach further into the vegetated corridor than allowed by CWS. Finally,some of the impacts to vegetated corridor are simply the result of modifications to CWS'enhancement.These modifications to provide safety corridors along portions of the regional and secondary trail have been approved by CWS. These areas will remain vegetated,though mowing and trimming of trees and shrubs will occur periodically to provide clear sight lines within the vicinity of the trail.This is being implemented as a measure to improve safety along the trail(as allowed in Section 18.775.090.6.5.e.). 18.775.140 Significant Habitat Areas Map Verification Procedures A Wildlife Habitat Assessment was completed by Pacific Habitat Services to address 18.775.140 and is included in this submittal. 18.790 Tree Removal An Arborist's Tree Plan and Report was completed by Walter H.Knapp&Associates to address 18.790 and is included in this submittal. The Demolition Plan—Sheet LD1.0 shows trees 6eing removed within the work limits. Preserved trees will be protected as noted on the Demolition Plan and Arborist's Report. Trees will be planted within vegetated communities as shown on the Landscape Diagram—Sheet L3.0. 18.810 Street and Utility Improvements No street or utility work is proposed for this project. 18.810.100 Storm Drainage Pagc� 7 . Provisions for stormwater are proposed to meet the standards of CWS. The CWS Service Provider Letter (SPL)is included in this application. A stormwater filtration memo is also included by KPFF Civil Engineers to respond to stormwater treatment for impervious areas. 18.810.110 Bikeways and Pedestrian Pathways The proposed trail is a multi-use path 10 foot wide asphalt trail with 12"gravel shoulders, proposed for pedestrian and bicycle users and serving as the regional multi-modal Fanno Creek Greenway Trail. This trail is recognized by the Fanno Creek Park Master Plan,Fanno Creek Trail Action Plan,City of Tigard TSP, and the Metro Regional Trails and Greenway System.The secondary trails,including the trail section through the high water area,will be 8 feet wide with 12"foot gravel shoulders.

Sc�nnad 7 t D �• Page 1 of 4 � ' � CWS rile Number �0-000519 ' CWS File No. 10-000519; Memo to Respond to Tier 2 Re�ulations Acceptance of the encroachment proposed as part of a T'ier 2 Alternatives Analysis shall be based on meeting all the following criteria: 1. The proposed encroachment area is mitigated in accordance with Section 3.08. • The proposed permanent Vegetated CoiTidor encroachments will be mitigated onsite (tax lots 2s�o2ACOO�oo,2s�ozn�a3000,and zsto2�soosoo) in accordance with Section 3.08 of R&O 07-20. 2. The reptacement mitigation protects the funetions and values of the Vegetated Corridor and Sensitive Area. • Replacement mitigation areas have been proposed in areas where continuity with existing Vegetated Corridors can be maintained. The proposed mitigation areas east of the Fanno Creek remeander and adjoining wetlands result in proposed corridor widths of up to 90 feet. The Vegetated Corridor west of the trail will be reduced to no less than 40 feet wide. West of Fanno Creek, the proposed Vegetated Corridor mitigation area will also be contiguous with the existing Vegetated Corridor. In addition,the Vegetated Corridor south of the trail will be as wide as l 30 feet. 3. Enhancement of the replacement area, if not already in Good Corridor Condition, and either the remaining Vegetated Corridor on the site o�• the first 50 feet of wiclth closest to thc resource,whichever is less, to a Good Corridor Condition. • The proposed vegetated corridor mitigation plan includes the enhancement oi�all replacement vegetated corridor to good condition. 13,216 sq. ft. of mitigation is proposed for enhancement. 4. A District Stormwater Connection Permit is likely to be issued based on proposed plans. • Not applicable. The project shall not require a Stormwater Connnection Permit. 5. Location of development and site planning minimizes incursion into the Vegetated Corridor. • Because of the remeander of Faimo Creek as a restoration project(approved under ER File No. 10- 000519), the existing trail location will be impacted; therefore, incursion into the Vegetated Corridor is necessary to replace the trail alignment. 6. No practicable alteroative to the location of the development exists that will not disturb the Sensitive Area or Vegetated Corridor. • Due to the nature of the project and the location of Sensitive Areas in the park, there are no trail alignments through the park that will not disturb Sensitive Areas or Vegetated Corridor. The proposed alignments follow existing alignments where possible. Where avoidance is not possible,the trail has been sited to minimize encroachment. The north-south trail section west of Fanno Creek was placed as far west as possible, to minimize impacts to proposed Sensitive Areas. This alignment ties back into the existing alignment just north of grading associated with the remeander. 7. The proposed encroachment provides public benefits. • Though maintaining a network of trails in Fanno Creek Park provides number public benefits, there is no direct benefit from a water quality standpoint. However,the proposed project is part of a comprehensive plan of urban renewal associated with a master plan for the park and adjoining areas. The trail project is in part the result of the need to maintain pedestrian traffic through the park following implementation of the Fanno Creek remeander. The creek project will itself result in a local benefit to water quality by increasing water storage and decreasing stream velocities, which results in less bank erosion and increased water quality. For the trail project,required enhancement will also provide water quality benefits.

March 16, 2010 FANNO CREEK PARK— PHASE I ARBORIST REPORT AND TRF.E PLAN too� Purpose This arborist report is the Tree Plan for the Fanno Creek Park project, specifically for Phase I, the City's trail realignment work. The Phase I project boundary also includes the Clean Water Services creek remeander work which is a separate project. This report is provided for Sensitive Lands Review per City of Tigard Code Chapters 18J75 and 18.790. This report describes the existing trees located within the Phase I project limits, as well as recommendations for tree removal and for tree retention and protection. Site Description The Phase I project boundary includes a natural area park with existing trails, a pedestrian footbridge crossing Fanno Creek, and trees scattered along the creek, trails, and across the site. A site visit was conducted on March 1, 2010 in order to collect tree inventory data. Sixty-two trees measuring six inches in diameter and larger were inventoried. Twelve species of trees were identified, with hawthorn, black cottonwood, and red alder accounting for approximately half of the inventoried trees. Table 1 provides a summary of the count of trees hy species. Table 1.

I.I.(' Tree Plan Recommendations Of the 62 inventoried trees, 21 are recommended for retention and 4l are recommended for removal. The trees to be retained will require special protection during construction and recommendations are provided herein. In addition, post- construction regular monitoring is recommended for all trees to be retained in order to evaluate trees for increased hazard potential. Safety pruning is also recommended for tree 117 if retained as recommended. Of the 41 trees recommended for removal, 30 appear in poor and hazardous condition, of which two are recommended for removal for condition and 28 are recommended for removal for both condition and construction. The remaining 11 trees are recommended for removal for construction with no major defects noted. Table 2 provides a summary of the treatment recommendations for trees locate within Phase I. Table 2.

No mitigation is required since more than 75-percent of the trees measuring over 12- inches in diameter located within the entire Fanno Creek Park property will be preserved as part of the entire project, which spans from Main Street to Hall Boulevard. Tree Protection Requirements Before Construction: 1. Trec Protection Zone. The project arborist shall designate the �I'ree Protection Zone (TPZ). Where feasible, the TPZ shall be established at the dripline of the tree or grove as a minimum. If infrastructure (roads, sidewalks, and utilities) must be installed closer to the tree(s), the TPZ may be established within the dripline area if the project arborist determines that the tree(s)will not be unduly damaged. The location of the TPZ shall be shown on construction drawings. 2. Protection Feneing. All trees to be retained shall be protected by chain link or other fencing as approved by the project arborist. Protection fencinb shall be secured to steel posts placed no further than 15 feet apart and shall be - installed at the edge of the TP7,. 3. Designation of Cut Trees. 'I�rees to be removed shall be clearly marked with construction flagging, tree-marking paint, or other methods approved in advance by the project arborist. 7615 SW Dunsmuir Lnne,Beaverlon,OR 97007 Phone:(503)646-4349 Fax:(503) 747-4863 ' Page 3 � 100�Fanno Realignment-Phase I :\rhonst Report 3-I6-IO.doc N uh�� I! f��iapp&Assocrates,LLC' 4. Preconstruction Conference. �I�he project arborist shall be on site to discuss methods of tree removal anci tree proteetion prior to any construction. During Construction: 1. Tree Protection Zone Maintenance. The protection fencin� shall not be moved, removed, or entered hy equipment except under direction of the project arborist. 2. Storage of Material or Equipment. The contractor shall not store materials or equipment within the �I�PI. 3. Excavation within the TPZ. • Excavation with the �fP"1, shall be avoided if alternatives are available. � If excavation within the TPZ in unavoidable,the project arborist shall evaluate the proposed excavation to determine methods to ininimize impacts to trees. This can include tunneling, hand digging, or other approaches. • All construction within the TPZ shall be under the on-site technical supervision of the project arborist. 4. Tree Protection Inspection. The project arborist shall monitor construction activities and progress, and provide written reports to the developer and the City at regular intervals. 5. Final Report. After the project has been completed, the project arborist shall provide a final report that describes the measures needed to maintain and protect the remaining trees. Summary Sixty-two trees are located within the Fanno Creek Park, Phase 1 project boundary. A complete description of individual trees is provided in the enclosed tree inventory. Twenty-one trees will be retained during construction and tree protection measures are recommended. Regular monitoring is recommended for these trees following construction and at least one should be safety pruned. The remaining 41 trees are recommended for removal for poor and hazardous condition and for the purposes of construction. No mitigation is reyuired since more than 75-percent of the existing trees measuring more than 12-inches in diameter will be preserved across the entire Fanno Creek Park property.

The study area for the assessment is located in Fanno Creek Park between SW Hall Boulevard and SW Main Street. As part of the City of Tigard's Master Plan, the City proposes to develop new and modified pedestrian trail sections in Fanno Creek Park. The project will include the realignment of existing trail sections, four new bridges over Fanno Creek(one new creek crossing, two location changes of existing bridges, and one realignment of an existing bridge),boardwalks, and adjacent sensitive areas habitat enhancements. Significant fish and wildlife habitat areas are present within the site, and are designated on the City of Tigard Significant Habitat Areas Map. Therefore, the purpose of this document is to address the City of Tigard's Sensitive Lands Ordinance 18.775.140 Significant Habitat Areas Map Yerification. As such, the Significant Habitat Areas Map is the basis for determining the general location of significant areas on or adjacent to the site. General Contractors • OR: CCB#94379 �WA: PACIFHS062QZ � Fanno Creek Park—Wildlife Habitat Assessment PHS Project No.4368 March 15,2010 Page 2 Pacific Habitat Services conducted two site visits on September 22 and 23, 2009, in order to assess the types and quality of wildlife habitat present within the Fanno Creek Park study area. Based upon the site visits and available site information, it appears that the study area includes varying degrees of wildlife habitat including a perennial waterway (Fanno Creek), wetlands, riparian forest associated with the creek, scrub-shrub, and open fields (see Attachment 1). The locations of wetlands and water bodies are shown in the concurrence letter and maps (Attachment 2) from the Oregon Department of State Lands (DSL) for the wetland delineation work conducted by SWCA Environmental Consultants in 2007 (DSL File No.: WD#07-0721). Attachment 3 is the "Fanno Creek Park Wetland Delineation and Natural Resource Assessment" map from the Natural Resource Assessment(NRA) submitted to CWS in 2008 (CWS File No.: 08-003606), this map shows the CWS-regulated vegetated corridors. The 100-year floodplain line is shown on Figure A (Attachment 4). Wildlife Habitat Assessment and Findin�s Species observed within the study area during the September site visits primarily consisted of birds including those listed in Table 1. Table 1.

Two fish species listed by the State and/or Federal Endangered Species Act(ESA) are present in Fanno Creek: Lower Columbia River Coho (Oncorhynchus kitsuch) ESU (State endangered and Federal threatened), and Upper Willamette River winter steelhead(Oncorhynchus mykiss) (Streamnet 2010). Best Management Practices (BMPs), including but not limited to, erosion and sediment control plans will be implemented prior to construction. Western pond turtles (Actinemys marmorata) are federally-listed as Species of Concern (SOC) and state-listed as Sensitive-Critical (SC). Although none were observed within the study area during the time of the site visits, their presence and nesting sites have been documented within undeveloped portions of City property and private property located east of the study area, immediately east of SW Hall Boulevard. These turtles have also been documented traveling back and forth across SW Hall Boulevard to and from Fanno Creek Park and these undeveloped parcels. Therefore, it is not unlikely that the turtles may be present at times within the Fanno Creek Park study area and adjacent areas, as these areas may provide potential refugia and over- wintering and summering habitat for the turtles. Fanno Creek Park—Wildlife Habitat Assessment PHS Project No.4368 March 15, 2010 Page 5 The proposed project will be limited to work within the limits of construction; for construction limits, refer to landscape plans (Site Plan, Shcet No. L 1-0)provided by WALKER MACY. Turtles are extremely sensitive to human and human-associated disturbances. In order to avoid and minimize potential impacts to this species, it is recommended that the City confer its proposed construction schedule with the area's Oregon Department of Fish and Wildlife (ODFW) wildlife biologist prior to commencing construction activities. The proposed trail improvements are within the vicinity of existing trails in Fanno Creek Park; however, it is unlikely that the trail improvements alone will deter the presence of turtles already using the site. In addition, the proposed vegetation enhancement plan for the adjacent vegetated corridor areas will provide continued connectivity to the surrounding area and habitat potential for the turtles. The surrounding areas adjacent to the project site are contiguous with and composed of similar type and quality of habitat as that of the project site. These adjacent areas will provide potential refugia for wildlife present at the time of construction. The areas adjacent to the completed trail system will be enhanced with native vegetation and remain contiguous with the sunounding areas within the park; therefore, the temporary loss of wildlife habitat during construction will not be permanent. The restoration of native plants will provide habitat and food sources to areas disturbed during construction in addition to supporting habitat in adjoining areas. Based on our site assessment of existing conditions within the study area and review of available site information, including wetland delineation and natural resource assessment reports, proposed project information, and the City of Tigard Significant Habitat Areas Map, PHS concurs with the the general location of designated significant habitat areas located on the Signifrcant Habitat Areas Map within the subject site.

Based on the information presented in the report, and additional information submitted upon request, we concur with the wetfand and waterway boundaries as mapped in the revised Figures 5A-5C. Within the study area, 13 wetland units (Wetlands A-G and I-N) and were identified, totaling approximately 10.69 acres. !n addition, the site has state waters consisting of�anno Creek and two side channels. The wetlands and waters are subject#o the permit requirements of the state Removal- Fill Law. Generally, a state permit is required far fill or excavation of 50 cubic yards or more in a wetland area or below the ordinary high water line of a waterway (the 2 year recurrence interval fload elevation, if OHWL cannot be determined). However, Fanno Creek is an essential salmonid stream; therefare, fill or removal of any amount ofi material below the ordinary high water line and in associated wetlands may require a state permit. Per the report, all wetlands except for Wetiands J and M are hydrologically connected to the creek. This concu�rence is for purposes of the state Remova!-Fill Law only. Federal or tocal permit requirements may apply as weEl. This concurrence is based on information provided to the agency. The jurisdic#ionaf determination is valid for five years from the date of this letter, unless new information necessitates a revision. Circumstances under � which the Department may change a determination and procedures for renewal of an � expired determination are found in OAR 141-090-0045 (available on our web site or � upon request). The applicant, Iandowner, or agent may submit a request for � reconsideration of this determination in writing within 60 calendar days of the date of this letter.

Fanno Park is located south of the intersection of SW Ash Avenue and SW Burnham Street in the City of Tigard, OR. Figure 1 shows the site location. The project will consist of the replacement of one of the existing pedestrian bridges with a new, approximately 70-foot span prefabricated steel truss bridge. In addition, a new 30-foot span glulam bridge will also be constructed over a new, excavated, water inlet channel. The approximate locations of the two bridges correspond with the locations of our boring locations shown on Figure 2. Borings B-1 and B-2 correspond approximately with the east and west abutment areas of the proposed 70-ft span steel truss bridge. Borings 6-3 and B-4 correspond approximately with the Northwest and South East abutments of the proposed 30-foot Glulam Bridge. 2.0 Purpose, Scope, and Proiect Understandin_q 2.1 Purpose of Work The purpose of our work was to provide a geotechnical engineering assessment of the site, as well as to provide recommendations for the proposed project. Our recommendations include: • Site preparation and excavation; • Grading; • Foundation design parameters; and • Other pertinent geotechnical design criteria and construction considerations. 2.2 Scope of Work Our scope of work for this project included: • A review of general geologic literature and previous geotechnical reports in the project vicinity; • Surficial reconnaissance; • Review of past subsurface explorations; • Geotechnical engineering analyses;and • Preparation of this report. Fanno Park Pedestrian Bridges,Geotechnical Foundation Report Page 1 City of Tigard,Oregon March 16,2010 1576-DO 3.0 Limitations Ash Creek completed this work in general accordance with the approved scope of work for the project. This work was performed for the exclusive use of Walker Macy, and their client(s} and consultant(s), for specific application to this project and site. The work was performed in accordance with generally accepted professional practices in the same or similar localities and related to the nature of the work accomplished at the time the services were performed. No other warranty, express or implied, is made. 4.0 Overview of Subsurface Conditions 4.1 Regional Geology The Tualatin Valley is a partially isolated northwestern extension of the Willamette Valley syncline (or trough) located between the Cascade Range and the Coast Range. The Tualatin Valley was most likely formed by a combination of major folding and crustal faulting, which resulted in more localized major down-warping (syncline formation) and uplifting (anticline formation). Fault displacement of as much as 1,000 feet is not uncommon. The resultant topography is characterized by a series of northwest-southeast trending valleys (Tualatin, Newberg and Wilsonvilie) and ridges (Tualatin Mountains, Cooper Mountain, Bull Mountain, and Parrett Mountain-Chehalem Mountains). The Tualatin Mountains and much of the basaltic terrain surrounding the Tualatin Valley are composed of the Columbia River Basalt(CRB) Formation, a Tertiary Age series of lava flows that erupted over a period of six to 17 million years before present (BP). The CRB has been down-warped, creating a northwest-southeast trending valley as much as 1,200 feet deep. The southwestern margin of the Tualatin Basin is composed of marine sedimentary rocks that make up the eastern margin of the Coast Range. The down-warped valley was subsequently filled with fine-grained, sedimentary fluvial (stream-borne) and lacustrine (lake) deposits derived from the surrounding hills, frequently termed the Troutdale Formation equivalent. More recently, near the end of the Pleistocene Epoch (up to approximately 14,000 years BP), large periodic glacial floods poured through the Columbia Gorge and deposited boulders, gravels, sands, and silts in the Portland Basin. Between the glacial floods, vast clouds of Aeolian (i.e., wind-blown) silt(loess} were swept off the Columbia River flood plain and deposited on the hillsides and valleys in the Tualatin Mountains and drainages. This silty aeolian deposit remains above approximately elevation 350 and have been named the Portland Hills Silt Formation, aged approximately 34,000 to 700,000 years BP (Lentr M.S. Thesis, 1977). Since the Pleistocene Epoch, the Tualatin Basin was filled with slackwater clayey silts from a series of floods spanning 10,000 to 34,000 years BP(Spokane or Missoula Flood Deposits), commonly known as the Willamette Silt Formation. The Willamette Silts extend the entire length of the Willamette Valley from Fanno Park Pedestrian Bridges,Geotechnical Foundation Report Page 2 Ciry of Tigard,Oregon March 16,2010 1576-00 Eugene to Portland. These deposits are generally found below Elevation 350, but some areas in the southern valley are thought to have exposures up to Elevation 400. The most recent deposits consist of recent (less than 10,000 years BP) alluvial deposits derived from erosion of nearby hilis and mountains. The alluvial deposits are most commonly found along active streams and rivers and in broad floodplains. Depending upon the source antl depositional environment, the alluvium can range from coarse sands and gravels to clay and peat. 4.2 Subsurface Explorations Ash Creek conducted subsurface explorations at both proposed bridge locations on February 18 and 19, 2010. Two borings were drilletl at each of the proposed bridge sites. Due to site access limitations, subsurface explorations were conducted with a small man portable"Big Beaver" drilling rig. The rig utilizes 4.5-inch O.D. solid stem auger. Standard Penetration Tests (SPT) were conducted at regular intervals in each boring. Detailed logs of each boring have been included in the appendices of this report. The following is a summary of the key subsurface conditions underlying the project. Topsoil. The areas adjacent to the existing walking trails are typically mantled in approximately 3 or 4 inches of silty topsoil. Fill. Shallow fill soils were observed in several of the borings. The fill soil typically consisted of soft or medium stiff,damp or moist, brown to gray, silt Native Soils Near the 70-foot Steel Truss Bridge. At the site of the Fanno Creek Crossing(the steel truss bridge),the native soils observed in our borings consisted of soft,damp to wet,gray,clayey silt to silt. Native Soils Near the 30-foot Glulam Bridge. At the site of the proposed inlet channel and glulam bridge, the native soils encountered consisted of very loose to medium dense, moist to wet, gray, silty fine sand or fine sand with a little silt. The sandy soils were observed to slough, heave and ravel. This will likely present challenges during all excavation work within this soil unit, particularly when attempting to advance trenches and excavations below the groundwater table. Groundwater. Groundwater at the time of our subsurface exploration was observed at depths of between 6 and 9 feet below the ground surface (bgs). It is likely that groundwater depths beneath the project site will generally fluctuate with surface water elevations within Fanno Creek. Excavation work occurring near the creek may require dewatering when such excavation work entails excavating below elevations corresponding to surface water elevations within the creek. Fanno Park Pedesbian Bridges,Geotechnical Foundation Report Page 3 Ciry of Tigard,Oregon March 16,2010 1576-00 4.3 Regional Seismicity The seismicity in the vicinity of the proposed project, and hence the potential for grountl shaking, is controlled by three separate fault mechanisms. These include the Cascadia Subduction Zone (CSZ), the mid-depth intraplate zone, and the relatively shallow crustal zone. Descriptions of these potential earthquake sources are presented below. The CSZ is located offshore and extends from no�thern California to British Columbia. Within this zone, the oceanic Juan De Fuca Plate is being subducted beneath the continental North American Plate to the east. The interface between these two plates is located at a depth of approximately 15 to 20 kilometers(km). The seismicity of the CSZ is subject to several uncertainties, inclutling the maximum earthquake moment magnitude (MW) and the recurrence intervals associated with various MW earthquakes. (M,,, is used by seismologists to measure larger earthquakes and is based on fault displacement and area of fault rupture while, for smaller earthquakes, the MW is approximately equal to the familiar Richter Scale Magnitude.) Anecdotal evidence of previous CSZ earthquakes has been observed within coastal marshes along the Oregon and Washington coasts. Sequences of interlayered peat and sands have been interpreted to be the result of large subduction zone earthquakes occurring at interoals on the order of 300 to 500 years, with the most recent event taking place approximately 300 years ago. A definitive study of Oregon seismic hazards completed by Geomatrix (1995) suggests that the maximum earthquake associated with the CSZ is M,,, 8 to 9. This is based on an empirical expression relating MW to the area of fault rupture derived from earthquakes that have occurred within subduction zones in other parts of the world. An M,�, 9 earthquake would involve a rupture of the entire CSZ. As discussed by Geomatrix(1995),this has not occurred in other subduction zones that have exhibited much higher levels of historical seismicity than the CSZ and is considered unlikely. For the purpose of this study, an earthquake of M„, 8.5 was assumed to occur within the CSZ. The intraplate zone encompasses the portion of the subducting Juan De Fuca Plate located at a depth of approximately 30 to 50 km below western Washington. Very low levels of seismicity have been obseroed within the intraplate zone in Oregon and southwestern Washington. However, much higher levels of seismicity within this zone have been recorded in the Puget Sound region and California. Several reasons for this seismic quiescence were suggested in the Geomatrix (1995) study and include changes in the direction of subduction between Oregon and British Columbia, as well as the effects of volcanic activity along the Cascade Range. Historical activity associated with the intraplate zone includes the 1949 Olympia (M,,,, 7.1) and the 1965 Puget Sound (M,�, 6.5) earthquakes. Based on the data presented within the Geomatrix (1995) report, an earthquake of M,N 7.25 has been chosen to represent the seismic potential of the intraplate zone. The third source of seismicity that can result in ground shaking is near-surface, crustal earthquakes occurring within the No�th American Plate. The historical seismicity of crustal earthquakes in western Fanno Park Pedesbian B�idges,Geotechnical Foundation Report Page 4 City of Tigard,Oregon March 16,2010 1576-00 Washington is higher than the seismicity associated with the CSZ and intraplate zones. The 1993 Scotts Mills(M,N 5.6)and Klamath Falls(M,,,6.0)earthquakes were crustal earthquakes. The maximum Mw associated with most of the near-vicinity fault zones is estimated to be less than 6.0 to 6.5 (the exception is the Portland Hills Fault, which has been determined to be capable of developing an M„,6.8 event). Seismic and geologic parameters such as slip rate, horizontal and vertical offset, rupture length, and geologic age have not been determined for the majority of the above faults. This is primarily due to the lack of surface expressions or exposures of faulting because of urban development and the presence of late Quaternary soil deposits that overlie the faults. The low level of historical seismicity (particularly for earthquakes greater than M,N 5) and lack of paleo-seismic data result in large uncertainties when evaluating individual crustal fault maximum Mw earthquakes and recurrence intervals. 5.0 Conclusions and Recommendations Our recommendations are based on our current understanding of the project. As the nature and level of detail associated with project design progress, Ash Creek should be contacted so that we may develop or revise our recommendations. Soil design parameters presented in the following sections were developed in accordance with the AASHTO LRFD Bridge Design Specifications(2007}. ` 5.1 Site Preparation Topsoil should be stripped from all embankment fill subgrade areas and road subgrade areas. Stripping depths within grassy areas will typically range from 3 to 4 inches. Localized areas of heavy brush or wooded area duff will require stripping depths of 4 to 8 inches. Topsoil stripping should not be reused in road embankment fills or structural fills. Subgrade Preparation. Soft subgrade soils encountered in areas of proposed embankment fills, structural fills, pavement subgrade areas, and shallow spread footing subgrade areas should be overexcavated. Failure to remove soft soils from these areas could result in long-term differential settlements within the proposed structure or cracking and/or pot-holing within new pavements. The overexcavated areas will require backfilling with compacted structural fill. We recommend use of select granular fill within overexcavated areas. Fanno Park Pedestrian Bridges,Geotechnical Foundation Report Page 5 City of Tigard,Oregon '" March 16,201 D 1576-00 5.2 Compaction Recommendations Significant embankment fill construction is not presently anticipated for the proposed project. Materials employed in embankment fills and structural fills should be free from organics and clay. Topsoil should not be reused in embankment fills or structural fills. Embankment fills that are constructed should be installed on a subgrade that has been prepared in accordance with the above recommendations. Fills should be installed in horizontal lifts not exceeding 8 inches in thickness (loose—prior to compaction). Fill materials should not be placed as in embankments fill or as backfill until excess moisture within the fill soil is within minus 4 percent to plus 2 percent of optimum moisture as determined by laboratory moisture-density relationship testing (AASHTO T-99 Standard Proctor Test). The embankment shoultl be compacted to at least 95 percent of the material's maximum dry density. In addition to moisture-density testing, conduct at least one deflection test according to ODOT TM 158 for each 3 feet, or portion of 3 feet, of embankment placed. If the layer being tested exhibits any yielding, deflection, reaction,or pumping, rework the area to provide acceptable test results prior to placement of any additional material. This may entail ripping and soil turning to promote soil drying via aeration, sun, and windrow drying. 5.3 Embankment Fills and Structural Fills Embankment and structural fills should be installed on a subgratle that has been prepared in accordance with the above recommendations. Final embankment fill slopes should not exceed finished gradients of 2H:1V for fills that do not terminate or cross into pond or creek areas. Fill slopes should not exceed slopes of 3H:1V for pond area side slopes of slopes that will be located in creek or pond areas. In order to achieve acceptable levels of compaction, it is generally desirable to maintain moisture contents of embankment fills to within the range of 3 to 4 percent of the optimum moisture content. During extended periods of warm dry weather,the on-site native soils can be aerated via air drying and soil turning to remove excess moisture. During wet weather grading,fill materials should consist of clean granular material. Structural fills or embankment fills placed over ground with slopes in excess of 5H:1V should be keyed and benched into existing slopes. Seeps encountered during grading on sloping ground should be intercepted via area drains. Outfalls for such drains should be routed to the toe of such slopes and should not be allowed to drain freely over slopes. Area drains are typically field-designed on a case-by-case basis. Usually seeps will be intercepted via 6-inch perforated drain pipes surrounded by clean crushed rock or drain-rock fill. Fanno Park Pedestrian 8ridges,Geotechnical Foundation Report Page 6 City of Tigard,Oregon March 16,2010 1576-DO 5.5 Foundations Overview. This section detaiis possible foundation options best suited to subsurface conditions and limitation of structural settlements to tolerable levels. Foundation design parameters were developed in accordance with AASHTO LRFD Bridge Design Specifications, 2007 Edition, Chapter 10. The native soils underlying the site will function adequately as load-bearing strata for lightly loaded structures founded upon conventional, shallow, spread footings. This could potentially include short to medium-height retaining walls antl wing walls depentlent upon backfiil loading conditions and wall geometry. In addition deepened spread footings should function adequately for both bridge locations as foundations loads for both bridge locations are anticipated to be light to moderate. Moreover it is our understanding that bridge foundation loads will not exceed approximately 75 kips per abutment. If structural loads are determined to be higher than 75, we should be informed so that we can reassess both our foundation bearing estimates and settlement estimates. 5.5.1 Shallow Foundations Lightiy loaded structures can be supported on shallow, spread foundations. The near-surface native soils adjacent to the bridges will function adequately as bearing strata for conventional spread footings for light to moderately loaded fountlations. For wall or retaining wali line loads not exceeding 6 kips per lineal foot (Klfl or point loads not exceeding 75 kips, we recommend that foundations be designed for a factored bearing resistance (qR) of 1.3 kips per square foot (Ksfl. The factored bearing resistance assumes a footing depth (Dfl in excess of 2 feet bgs. Total settlement of foundations designed under the above conditions should be less than 1 inch and differential settlements between individual footing elements are not anticipated to exceed 0.5 inch. Deepening foundations will result in a higher qR. For footings established at least 6 feet below all surrounding grades, a qR of 2.9 Ksf can be employed for sizing purposes.

The foundation design values presented above can be increased by 1/3 for short-term loading such as wind or seismic. Foundation Subgrade Preparation for Bridge Abutments and Retaining Wall or Wing Walls. The foundation subgrade soils exposed at the base of footing excavations will likely be soft and wet. We recommend that a minimum of 12 inches of clean compacted crushed rock be placed over the foundation subgrade to both establish a firm work base for foundation work and to dampen long-term elastic settlement beneath the bridge foundations. The crushed rock should be placed over a geotextile filter fabric. This crushed rock pedestal should extend a minimum of 12 inches beyond the edge of the footing itself in all Fanno Park Pedestrian Bridges,Geotechnical Foundation Report Page 8 City of Tigard,Oregon March 16,2010 1576•00 directions. The crushed rock back fill should consist of either'/4-inch(-) or 1-inch(-) material containing less than 6 percent fines by weight. The crushed rock petlestal should be compacted to at least 95 percent of the material maximum dry density as determined by ASTM D-1557. 5.6 Retaining Walls and Wing Walls Soil conditions and earth pressure for all walls were developed in accordance with the AASHTO LRFD Bridge Design Specifications, 2007 Etlition. The type of earth pressure used for design depends on the ability of the wall to yield in response to the earth loads. For walls that are free to translate or rotate (i.e., flexible walls), active pressures shall be usetl in the retained soil. Flexible walls are further defined as being able to displace laterally at least 0.001 H,where H is the height of the wall. Standard concrete walls, mechanically stabilized earth (MSE) walls, soil nail walls, soldier pile walls, and anchored walls are generally considered as flexible retaining walls. Non-yielding walls shall use at-rest earth pressure parameters. Non-yielding walls include, for example, integral abutment walls, wall corners, cut-and-cover tunnel walls, and braced walls(i.e., walls that are cross-braced to another wall or structure). Where bridge wing and curtain walls join the bridge abutment, at-rest earth pressures should be used. At distances away from the bridge abutment equal to or greater than the height of the abutment wall, active earth pressures may be used. This assumes that at such distances away from the bridge abutment, the wing or curtain wall can deflect enough to allow active conditions to develop. We have evaluated the proposed retaining walls and wing wall in accordance with Chapters 3, 10,and 11 of AASHTO LRFD Bridge Design Specifications, U.S. Customary, 4th Edition, 2007; Sections 15.4.2.7 and 15.4.2.9 of the ODOT GDM; and detailed the appropriate soil design parameters in the foliowing tables. Soil cohesion should be assumed as zero.

Precautions in utility trenches and other excavations will be requiretl due to the potential for cavinglsloughing within native soils underlying the site. Any excavations deeper than 4 feet should be sloped or shored in accordance with Occupational Health antl Safety Administration (OSHA) regulations. Normally, shoring systems are contractor-designed and -installed items. The contractor will therefore be responsible for temporary shoring systems. Subgrade soil at the base of trenches and excavations should be firm, or dense, prior to the placement of bedding, or base material. The base of excavations and trenches should also be free of mud and muck, and should be sufficientiy stable to remain firm and intact under the feet of the workmen. Where necessary,a layer of lean mix or clean gravel of su�cient strength and thickness to withstand subsequent construction activity should be placed at the base of trenches and excavations. This will require installation below the specified subgrade elevation. Trenches and excavations near or below the groundwater table may require dewatering to reduce the potential for base heave,flowing soil,and sidewall blowouts. Temporary Excavation Slopes and Shoring. In general, temporary excavation slopes may be suitable in areas where adjacent improvements are not located within a horizontal distance equal to the depth of the excavation(measured from the top of the excavation}. Unsupported temporary excavation slopes within native fine-grained soils or embankment fill soils should not exceed slopes of 1H:1V in the dry or 2.5H:1V in wet sandy soils or cuts that will be advanced below either surface water elevations the groundwater depths. Actual slopes used during construction should be determined by the contractor on a case-by-case basis. We anticipate that the majority of the utility excavations will be constructed using "co�n-box"-type shoring and vertical excavation slopes. Foundation Subgrade. Excavations for spread footings should be prepared in accordance with the recommendations in the foundation section of this report. Heaving and Sloughing Sands. Heaving, raveling/sloughing, saturated sandy soils were encountered in several of our borings. These types soils are typical of ineandering creek and stream areas. Both the General Fanno Park Pedeshian Bridges,Geotechnical Foundation Report Page 10 City of Tigard,Oregon March 16,2010 1576-00 and Earth Work Contractors should be prepared for the challenges associated with advancing excavations and trenches into these types of soil conditions. Dewatering. For excavations near or below the groundwater table, intensive excavation dewatering will be required. Shallow groundwater should be anticipatetl throughout the site. We expect that dewatering via well points within these areas will be required prior to starting excavations. Attempting excavation within the project boundaries without dewatering prior to the commencement of excavation will result in extreme caving and heaving. This will result in significant project delays, large amounts of additional excavation work, as well as the requirement for increased quantities of backfill. In addition, significant caving and heaving can result in the undermining and settlement of adjacent structures, pavements, roads, sidewalks, utilities, etc. For all excavations, the groundwater table should be maintained at a minimum of 2 feet below the depth of excavation. Draw-down of the water level should be maintained from before subgrade excavation until after the excavation has been backfilled. In the case of trenches, the dewatering should be conducted by means of well points or other acceptable means until the pipe has been laid and backfill has been completed to a stage where tlanger from flotation or base heave is eliminated via the downward pressure exerted by the trench backfill. The disposal of the wastewater from dewatering operations should be 6ght-lined to existing disposal locations(i.e.,ditches, channels,or drains)subject to permit approval. Settlement of suspended silt or sand will likely be required prior to discharge of wastewater from trench and excavation dewatering. Surface water and rainwater runoff should be diverted to prevent it from entering trenches and excavations to the greatest extent possible without damage to adjacent property from dikes, ditches, or impounded water. From the perspective of potentially reducing the amount of project dewatering, groundwater levels will typically be at their deepest levels from mid-summer through early fall months; however, even during summer months significant dewatering will still be required in trenches and excavations. 6.0 Additional Geotechnica/ Services Prior to construction, we recommend that Ash Creek be retained to review the final design plans and specifications. This review will allow us to evaluate whether any change in concept may affect the validity of our recommendations and whether our recommendations have been correctly interpreted; to correlate preliminary soil data with actual soil conditions encountered during construction; and to assess construction conformance to our report.

Summary of No-Rise Condition within the Project Area..................................... 6 Introduction This report describes the approach and presents the results of a hydraulic analysis conducted for the proposed improvements of portions of Fanno Creek Park between Highway 99W and the Ash Avenue pedestrian bridge in Tigard, Oregon. The purpose of this project is to restore channel planform and morphology for a reach that was previously straightened, enhance the pedestrian facilities in the park, and improve fish and aquatic wildlife habitat in the surrounding areas. The topics addressed in this report include: ■ General site description (including a description of existing conditions and the proposed project enhancements) ■ Regulatory and municipal standards including floodplain development regulations ■ Site hydrology ■ Stream channel hydraulic analysis ■ Analysis results and no-rise summary Hydraulics Report 1 Lower Fanno Creek Park Project Site Description `I'he Lower Fanno Creek Park Project is located in Tigard, Oregon between Highway 99W to the north and the Ash Avenue pedestrian bridge to the South (Figure 1). Fanno Geek itself flows generally south from its origin in the West/Vermont Hills of Portland, through portions of Washington County, Beaverton, and Tigard to its confluence with the Tualatin River at Durham. The project site is situated downstream of historic downtown Tigard and adjacent to City Hall and includes a series multi-use trails making it an important recreational area for the community. Existing Channel Characteristics Presently within the project site, Fanno Creek shows signs of a changing stream as a result of past development in the basin. The channel is incised in a number of locations and failing banks are not uncommon. Immediately downstream of Highway 99W, the channel has very little complexity, having been straightened and realigned to its present location in the 70's during a large sewer project. The average bankfull width and depth of the channel is 31 feet and 6.8 feet respectively, which are significantly less than what would be expected given the channel's soils, morphology and flow regime. The overall longitudinal slope within the project area is relatively flat at 0.2%, resulting in channel and overbank flood velocities consistently less than 4 and 2 fds during a 100-year flood. Vegetation varies considerably throughout the site, ranging from dense blackberries to stands of deciduous trees to maintained grasses for recreation. The project reach currently includes three bridges. From upstream to downstream they are the Highway 99W bridge, A-Boy pedestrian bridge, and Ash Avenue pedestrian bridge. Proposed Channel Improvements The following paragraphs describe the proposed conditions for the project site separated into three areas; 1) a reconstructed channel meander, 2) construction of a wetland habitat area, 3) replacement of the existing pedestrian path and the addition of new pedestrian bridges at Ash Avenue and the confluence of a small tributary upstream of Ash Avenue. Because the bridge over the tributary is a glulam structure, the tributary is referred to Glulam Creek in this report. See the design drawings submitted with this permitting package for more detailed information. Channel Meander The proposed channel meander is approximately 1000 feet long and is comprised of a two-stage cross-section with a bottom width of l 1 feet, a top width varying from 37-45 feet depending existing �round elevations and 1:1 side slop�,s. Although relatively steep, the side slopes were chosen to reflect natural bank conditions seen in more established reaches of Fannu Creek. The channel benching elevation has been set to 3.5 feet above the channel bottom to provide adequate water depths during average summer low flows and varies horizontally depending on its location within the sinuous channel planform. The longitudinal profile of the channel includes pool-riffle sequences at each meander curve, with approximate pool depths and lengths set to 3 feet and 50 feet respectively. To establish and maintain the pool-riffle sequence and to strengthen the outer banks of the constructed channel, combined root wad/log/j-hook structures are included above each pool. At the downstream end of the newly realigned channel,the existing Ash Avenue pedestrian bridge is slated to be removed and replaced with a larger bridge(described below). Due to the presence of buried utilities at the crossing, a constructed riffle with habitat boulders Hydraulics Report 2 Lower Fanno Creek Park Project followed by series of grade control structures has been included to maintain the integrity of the utilities. Wetland Habitat Area In the abandoned channel area formed by the newiy constructed channel meander, a wetland habitat area has been included as a series of shallow ponds. Flows entering these ponds come from both a natural drainage to the northwest and runoff from the southwest. The area is intended to provide aquatic wetland habitat, however stormwater treatment may occur as a secondary benefit. Habitat logs have been included in the ponds for complexity and the outfall back to Fanno Creek is design as a vegetated riprap chute. The total area and volume of the constructed wetland is approximately 30,000 square feet and 3,300 cubic yards, respectively. Pedestrian Path and Bridge Replacements/Additions The existing pedestrian path between the Ash Avenue bridge and the reconnection location of the channel meander will be removed and relocated west of the wetland habitat area. The existing Ash Avenue pedestrian bridge will be removed and replaced with a prefabricated steel truss bridge. The low chord of the new Ash Avenue bridge will be set at the approximate elevation of the 2-year storm water depth, which is above the current low chord elevation. In addition, a new bridge will be constructed at the Glulam Creek crossing. Currently, a 48-inch diameter culvert conveys Glulam Creek flows under the existing path into Fanno Creek. The culvert will be removed and replaced with a bridge having a low chord elevation set at the approximate 2-year storm water depth. Regulatory Standards The goal of the Fanno Creek Enhancement Project is to conform to the standards specified in the Clean Water Services Design and Construction Standards, the Washington County Submittal Requirements for Floodplain and Drainage Hazard Areas, and other applicable local regulations. The entire project area is located within the effective 100-year floodplain of Fanno Creek(Flood Insurance Studyfor the City of Tigard, Oregon, Washington County, February 18, 2005). In addition, floodways also present throughout the project area and a majority of the project impacts are located within the floodway. In terms of the net effect to flood elevations,the design of all channel improvements conforms to the City of Tigard's municipal code, Chapter 18.775, which states the City's goal of preserving natural sensitive areas from encroaching uses and to maintain a zero-foot rise condition for the floodplain when compared to existing conditions. Other Regulatory Targets [n most cases, rock structures used will be countersunk below finished grade and covered with native streambed materials. Native streambed materials can be stockpiied during excavation and stored above the bankfull elevation until reused. If stabilization is necessary above the Ordinary High Water Elevation, the Contractor will use bioengineering techniques as the primary means of achieving such stabilization. Hydraulics Report 3 Lower Fanno Creek Park Project Hydrology Design flows were established for the project using results from two sources; 1)the hydrologic analysis from the Fanno Creek Watershed Management Plan (Unified Sewerage Agency of Washington County„ 1997) and 2) flows documented in the effective Flood Insurance Study for Fanno Creek in the City of Tigard (FEMA, 2005). Flows from the 1997 Fanno Creek Watershed Management Plan, which are believed to be more accurate that the FEMA flows, were compiled and used for the design of the channel and spot treatments. Data from the plan include stream nodes at key locations including bridges, tributaries and cross sections throughout the reach. Both existing and future condition flows are provided at each location and both were used during the design process to establish critical elevations for channel banks and habitat structures. .� . •� ..• �• . • Location 2•Yr 5-yr 10•yr 25-yr 50•yr 100•yr 500•yr (cfs) (cfs) (cfs) (cfs) (cfs) (cfs) (cfs) N o Highway 99W 1,254 1,633 1,873 2,183 2,407 2,637 3,207 � � c� Tributary downstream of 99W 1,273 1,654 1,894 2,204 2,426 2,655 3,227 � � w Hall Blvd 1,275 1,651 1,887 2,195 2,412 2,636 3,198 o Highway 99W 1,360 1,803 2,072 2,424 2,658 2,898 n/a � � � Tributary downstream of 99W 1,364 1,805 2,072 2,426 2,661 2,896 n/a � `_ ,i Hall Blvd 1,417 1,871 2,142 2,506 2,751 2,999 n/a Flows rates from the 1999 FEMA Flood Insurance Study(extracted from the effective HEG2 model) were used to prepare the No-Rise Flood Certification letter to conform to Clean Water Services Design and Construction Standards and the City of Tigard's municipal code. Based on subsequent work done as part of the 1997 Fanno Creek Watershed Management Plan, it is acknowledged that the FEMA flows may be somewhat high. However, for consistency with the effective regulatory floodplains,the FEMA flows were used to confirm the no-rise condition is being met for the project. This is a cons�rvative approach since it confirms a no-rise condition far a wider range of flows. .. • �• . � Lacation(Section ID) 10•yr(cfs) 50-v,r(cfs) 100-yr(cfs) 500-;r(cfs) Upstream of Tiedeman Ave(32646) 2,733 3,518 3,869 4,700 Upstream of Hwy 99W(26370) 2,845 3,672 4,038 4,901 Downstream of Main St(26008) 2,858 3,695 4,063 4,932 600 ft Upstream of Hall Bivd(22618) 2,862 3,702 4,072 4,943 Downstream of Hall Blvd(21597) 2,889 3,749 4,125 5,009 Hydraulics Report 4 Lower Fanno Creek Park Project Hydraulics The hydraulic conditions of Fanno Creek were analyzed using the U.S. Army Corps of Engineers' HEGRAS model (version 4.0). A single model, originally developed in HEG2 for the Fanno Creek Watershed Management Plan was created for the entire stream reach from immediately downstream of SW Tiedeman Ave to its confluence with the Tualatin River. Prior to making any model revisions, the original HEC-2 model was converted to HEC-RAS and the results were compared to one another and the water surface profiles in the effective FIS to confirm overall consistency. Within the original project area(Highway 99W to Hall Blvd), the model was refined by replacing the 8 unique HEC-2 cross-sections with 50 new sections extracted from survey data collected during 2007 as part of this project. Although the model was developed for the entire Fanno Creek reach between Highway 99W and Hall Boulevard, the results discussed in this report are specific to the project area between the Ash Avenue pedestrian bridge and Highway 99W. Figure 2 illustrates the location of the new model cross-sections. With the baseline model complete, two scenarios were evaluated; existing conditions and proposed conditions. Hydraulic analyses were performed using the steady-state computational method, with downstream boundary conditions established at the Tualatin River from corresponding return-period water levels. This is consistent with the previous FEMA/HEC-2 modeling. Channel and overbank roughness values (Manning's "n") ranging from OA25 to 0.091 were assigned to each cross-section within the project reach based on values used in the original HEC- 2 model and estimates of surface roughnesses.At each section,the roughness values were compared to field observations and values published in Open Channel Hydraulics(Chow, 1959) to confirm their applicability. Hydraulics Report 5 Lower Fanno Creek Park Project Analysis Results Due to the significant grading and excavation activities within the channel and floodplain (nearly 1 1,000 cu-yds or material will be removed from the site), it was initially anticipated prior to any modeling that 100-year water levels throughout the project area would be reduced. Based on results from the steady-state HEC-RAS analysis, this conclusion was confirmed along the entire stream channel. At each model cross-section within the project area and upstream of Highway 99W, water levels remain unchanged, or are reduced by as much as 0.2 feet. Table 3 and Figure 3 illustrate these results at five key locations throughout the project reach and Figure 4 illustrates a continuous profile of existing and proposed water levels throughout the project area.

Vegetated filter strips are proposed along the edges of the Fanno Creek trail as part of the re-meander project within Lower Fanno Creek Park in Tigard, Oregon.The filter strips will be gently sloping areas that are designed to receive sheet flow from the adjacent impervious trail. The facilities run parallel to the length of the trail and will be filled with plant material capable of slowing sheet flow to provide pre-treatment and promote infiltration. According to the CWS 2007 Design and Construction Standards Manual, vegetated filter strips are acceptable for use in public systems and are a viable Low Impact Development Approach to stormwater runoff treatment (Table 4-2). CWS has a form for properly sizing the vegetated filter strips. A single facility (vegetated filter strip areaj can treat a maximum of 15,000 square feet of impervious area. The trail section includes a 10-foot wide landscaped improvement area on either side of the path that is more than adequate in effectively treating the stormwater prior to conveyance into the adjacent Fanno Creek. The terrain of this path is relatively flat with minimal slopes.Throughout the project it is anticipated that storm flows will primarily flow across the trail. On the east side of Fanno Creek there is a large existing vegetated buffer between the new trail and the creek that will effectively treat the storm drainage prior to entering the waterway. On the west side of Fanno Creek, the stormwater will pass through the vegetated filter strip prior to entering into the CWS high water area shown on the plans. The CWS high water area will promote additional treatment and settlement prior to storm flows entering the main channel of Fanno Creek.

Answers were provided by Ben and Jeff. Q: Where is the regional trail going through Fanno Creek Park up to Ash? Why is it not shown on the plan? A:The seciion of the regional trail going through the Pubfic Works yard is not part of the Phase 1 project. !t is not shown because it has not been designed. � Q: I don't see why you need a 10'wide regional trail. A:The regiona!trail width is a guideline set 6y Metro. Comment from public participant—I believe the 10'trail width is for fire life and safety access. Comment from public participant—There is flexibility in the trail width. Across Hall Blvd,the trail and bridge were reduced to 8'wide. There should be some flexibility in the trail width. Q: How many more segments are required to complete the entire Fanno Creek Trail system? A:Not sure how many more segments are required io complete rhe troil. Q:Will you be repaving the trails? A: Yes, the irails that are affected by the Clean Water Services remeander wi!!be repaved. Q: I was told you were moving the trail away from Verizon? A:The moster pJan shows the trai!moving away from the Verizon property but ir is noc a part of this project. Q:What is your schedule to do Phase 1? A: This summer if possibfe during the in-woter work period, but it moy go nexf summer. Q:What is the Sensitive Lands Review? A:li is a review process you go through when you are in o sensifive areo like weilonds ond a floodplain. The trail is in the flood plain and has to go through rhe Sensitive Londs Review. Comment from participant—The postings in the park are great. Hard to miss. Q: How do I get notified about this meeting? If someone didn't tell me, I would have never known this meeting was going to be held. A: The neighborhood meeting process requires notificotion of residences within o 500'radius of the pork, organizaiions, and interesied parties. Q: How do I become an interested party? A:The question was answered by a member of the public—Mr. Frewing indicoted that you have io go io the City and sign up[o be nocified for upcoming projects in the City. Comment from public participant—The City needs to clarify street naming. We keep seeing Ash Street on the plans when this is Ash Avenue. Leads to confusion and would appreciate identifying Ash Ave correctly. The same participant also stated that he welcomes any proposed development within the park. Q:The master plan shows two dashed lines going across the trail. What are those lines? Improvements to the bridge would move it sideways to facilitate a roadway in the future. A: Those are left over lines from previous traffic studies showing possible roodway connections. They werer not port of the master plan study done by Walker Macy but provided to us to show on our plans. Kim McMi!!an stepped in to clorify the response. She indicated that there is right-of-way in the TSP that shows a future connection of Ash Avenue through the park. Wheiher or not ii will ever happen will be based on funding and a decision in the future. Q:Can citizen participation remove the right-of-way going through the park? A:Kim McMillan wos not sure and said citizens could tafk to planning staff. Q:Are trails staying in the same location? A:The trails are basically staying in the same location but we wil!be modifying the grades to motch the new bridge elevations. The new grades wil!be ADA compliant and S%maximum. Q:Where are the boardwalks? Weren't they in the master plan? A:The trai!was moved over io the south and a qlulom bridge was designed over the stormwaier channel. The boardwalks were eliminoced because they were too expensive. Q: Is the bank that is being eroded along the creek to the northwest being fixed with the project? A:The trail improvements end prior to ihe erosion area. Jeff stated that the City was looking at some bank stobilizotion projects, but he is not sure if ihis area is included. Comments provided by public participants—The garbage cans in the park are always full and do not get emptied enough. There is a fence down by Ash Avenue that needs to be removed. There is a lot of trash in the creek that needs to be cleaned up. The transients are the major reason why the area has so much trash. This is a maintenance and police monitoring issue. Q:Your project plan is different from the master plan. Do you have flexibility? A:The plans are minor tweaks from ihe master plan. Q:Can you eliminate the regional trail from Ash Avenue to Max's Pub and push the trail up Ash Avenue towards eurnham? A:!f the regiona!trail is shifted to Ash then we would be cutiing areos of the park off. The goal is to plug the gaps and not create new ones. Q:What is the funding source for this project and what is the estimate? A:The funding sources are park SDC's and the genera!fund. The estimate is being worked out,bur the project wil! likely cost between$250,000-$300,000. Q:Will you use wire mesh on the sides of the new Ash Ave bridge? A:No wire mesh, likely steel bars along ihe side. Q:Are you going to be using pervious pavement or regular asphalt? A:Regular asphalt. Pervious pavement creafes a major maintenance issues. The trail is in a flood plain and ii � would hove to be cleaned every time woter comes over it. Response from public participant—Good. Q: Are you adding much planting? A:CWS is doing the majority of the plantings with their project. The focus is on plant communities. There will be more conirolled planting at trailheads as part of this project,possibly using containerized plonts. Q:Are you going to use large soil vaults? A:The soi!vaults will be 1-1/2 times the size of the containers. Q:Are you going to clean up woody debris before planting and doing the trail? Cleaning out of bunch of the area would help eliminate transient problems because they are more visible. Comment provided by public participant Sue Beilke—seen other trail areas that have been cleaned up. It doesn't help eliminate the transient problem and it destroys wildlife habitat. Q: Brought up to the public by public participant. Do you hear owls in the park? Two kinds of owls asked about. One is the skreetch owl. Didn't get the name of the second owl. One public participant indicated she has heard Screech owls.
