APPLICATION SUMMARY CASE: CITY OF TIGARD SEWER EXTENSION NEAR 106TH & JOHNSON Sensitive Lands Review SLR 99-0001 PROPOSAL: The applicant is requesting Sensitive Lands Review approval and Water Resources Overlay approval to extend a sanitary sewer line across a drainageway and City inventoried wetlands in order to provide sewer service to homes in the area. APPLICANT: City of Tigard OWNER: City of Tigard Project Engineer: Letha Thomas 13125 SW Hall Boulevard 13125 SW Hall Boulevard Tigard, OR 97223 Tigard, OR 97223 COMPREHENSIVE PLAN DESIGNATION: Low Density Residential; 1-5 Dwelling Units Per Acre. ZONING DESIGNATION: Single-Family Residential - 7,500 Square Feet Per Unit, 4.5 Units Per Acre; R-4.5. The purpose of the R-4.5 Zoning District is to establish standard urban low-density residential sites. The R-4.5 zone allows, among other uses, single-family residential units, public support facilities, residential treatment homes, farming, manufactured homes, family day care, home occupations, temporary uses, residential fuel tank, and accessory structures. LOCATION: Derry Dell Creek is approximately 500 feet east of the intersection of SW 106'h and SW Johnson Street. The proposed sanitary sewer line will cross the stream and continue west for approximately 400 linear feet along the centerline of SW Johnson Street where it will then connect to another sanitary sewer line at SW 106'h Avenue. APPLICABLE REVIEW CRITERIA: Community Development Code Chapters 18.390, 18.775 and 18.797. SECTION II.

Submit a copy of the permit approval from the US Army Corps of Engineers or a letter from said agency indicating that a permit is not required. 2. Install erosion control measures prior to construction. Erosion control measures may not be removed until construction has been completed. 3. Upon completion of construction, the site shall be restored to its original state with natural vegetation and replacement of soil. THIS APPROVAL SHALL BEVAtiDfOrt EIGHTEEN 418) MONTHS FROM THE EFFECTIVE DATE OF THIS DECISION. SECTION III. BACKGROUND INFORMATION. Site History: The area of SW Johnson Street and SW 106' Avenue was recently annexed into the City of Tigard so that city sewer services could be extended to serve the properties abutting these streets. Upon annexation a reimbursement district was formed which would allow the City to design and construct the sewer extension and then be reimbursed by the property owners. The sewer connection requires the crossing of Derry Dell Creek. Vicinity Information and Proposal Description: The sewer project is in an area zoned R-4.5. The sewer line will be extended across Derry Dell Creek, which is a minor stream on the Water Resources Overlay. There are City inventoried and jurisdictional wetlands within the area to be crossed. Because the proposal is to cross a drainageway, Sensitive Lands Review (SLR) approval is required. Because the drainageway is listed as a minor stream and identified on the City's inventory, Type II review is required for the Water Resources Overlay. SECTION IV. APPLICABLE REVIEW CRITERIA AND FINDINGS COMPLIANCE WITH COMMUNITY DEVELOPMENT CODE SECTIONS: SENSITIVE LANDS Section 18.775 states that the Director shall have the authority to issue a sensitive lands permit in the following areas by means of a Type II procedure, as governed in Section 18.390.040, using approval criteria contained in Section 18.775.070 C-E: • Drainageways; • Slopes that are 25% or greater or unstable ground; and • Wetland areas which are not regulated by other local, state, or federal agencies and are designated as significant wetlands on the Comprehensive Plan Floodplain and Wetland Map. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 2 OF 12 Drainageways. The appropriate approval authority shall approve, approve with conditions or deny an application request for a sensitive lands permit within drainageways based upon findings that all of the following criteria have been satisfied: The extent and nature of the proposed land form alteration or development will not create site disturbances to the extent greater than that required for the use; The site disturbances are the minimum necessary to install the sewer extension. In addition, the ground will be returned to its original state after the construction has been completed. The proposed land form alteration or development will not result in erosion, stream sedimentation, ground instability, or other adverse on-site and off-site effects or hazards to life or property; The applicant has submitted an erosion control plan that shows erosion control measures will be employed during the construction period. In addition, the US Army Corps of Engineers permit will regulate erosion control. The water flow capacity of the drainageway is not decreased; The proposed extension will not affect the water flow capacity of the drainageway because the alteration is temporary and the ground after construction will be restored to its original state. Where natural vegetation has been removed due to land form alteration or development, the areas not covered by structures or impervious surfaces will be replanted to prevent erosion in accordance with Chapter 18.745, Landscaping and Screening; The applicant's narrative states that natural vegetation will be replanted upon completion of the project. A condition of approval will be attached requiring the area to be restored to its original state upon completion of the sewer extension in this area. The drainageway will be replaced by a public facility of adequate size to accommodate maximum flow in accordance with the adopted 1981 Master Drainage Plan; The drainageway is not being replaced, therefore, this standard does not apply. The necessary U.S. Army Corps of Engineers and State of Oregon Land Board, Division of State Lands (DSL) approvals shall be obtained; The applicant has submitted for permit approval from DSL and the US Army Corps of Engineers. DSL has stated that the wetland delineation has been approved and no permits are required. The US Army Corps of Engineers has indicated that a permit is required but has not been approved yet. A condition of approval will be attached requiring that evidence of permit approval be submitted prior to the start of any construction within this area. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 3 OF 12 Where landform alterations and/or development are allowed within and adjacent to the 100-year floodplain, the City shall require the consideration of dedication of sufficient open land area within and adjacent to the floodplain in accordance with the Comprehensive Plan. This area shall include portions of a suitable elevation for the construction of a pedestrian/bicycle pathway within the floodplain in accordance with the adopted pedestrian bicycle pathway plan. The area of alteration is not within or adjacent to a floodplain, therefore, this standard does not apply. FINDING: Based on the analysis above, the applicant's plan will fully comply with the SLR standards for alteration in drainageways provided that the required permits are obtained from the US Army Corps of Engineers. CONDITION: Submit evidence of permit approval from the US Army Corps of Engineers or a letter from the appropriate representative at the US Army Corps of Engineers that permit approval is not required. WATER RESOURCES DEVELOPMENT STANDARDS (18.797.080) The following shall apply to all development, including native vegetation removal and excavation, within the WR overlay district. No application for a use identified in Section 18.797.050 shall be deemed complete until the applicant has addressed each of these standards in writing. Alternatives considered. Except for stream corridor enhancement, most Type II and III uses are expected to develop outside of water resource and riparian setback areas. Therefore, Type II and III development applications must carefully examine upland alternatives for the proposed use, and explain the reasons why the proposed development cannot reasonably occur outside of the water resource or riparian setback area. Due to the topography of the area, there are no alternate routes available to provide sanitary sewer service to the properties seeking service. Therefore, no other alternative could be considered. FINDING: Because the applicant has provided information indicating that no alternative location is available due to the topography necessary to provide sanitary sewer service to the properties, this criterion has been satisfied. Minimize siting impacts. The proposed use shall be designed, located and constructed to minimize excavation, loss of native vegetation, erosion, and adverse hydrological impacts on water resources. For Type II and III uses, the civil engineer with experience in water quality must certify that any adverse water quality impacts of the development proposal will be minimized consistent with best management practices; SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 4 OF 12 For all uses, the development shall be located as far from the water resource, and use as little of the water resource or riparian setback area, as possible, recognizing the operational needs of the proposed development. The applicant's narrative states that every attempt has been made to insure minimum impact to the water resources. The project has been designed under the supervision of a Civil Engineer licensed in Oregon, and any adverse impacts will be minimized consistent with the best management practices. Staff concurs that the proposal has been designed to minimize impacts as much as possible given that the crossing of Derry Dell Creek is necessary in this location. FINDING: Because the proposal was prepared by an Engineer utilizing best management practices and will minimize the impacts will be minimized as much as possible, this standard has been satisfied. Construction materials and methods. Where development within the riparian area is unavoidable, construction materials or methods used within the riparian setback area shall minimize damage to water quality and native vegetation. The applicant's narrative indicates that the proposed construction will follow adopted City of Tigard, Unified Sewerage Agency (USA), DSL and US Army Corps of Engineers materials and methods for work in wetland areas. Erosion control methods will insure that impact to the drainage during construction is minimized and vegetation removal will be limited to the work area and replaced after the project is completed. FINDING: Because the applicant has proposed methods which will insure that damage to the water quality and native vegetation will be minimized, this standard has been satisfied. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Minimize flood damage. Above-ground residential structures shall not be permitted within the WR overlay district, where such land is also within the 100-year floodplain. On-site flood storage capacity shall not decrease as a result of development. The cumulative effects of any proposed development shall not reduce flood storage capacity or raise base flood elevations on- or off-site. Any new commercial or industrial land development proposed within the 100-year floodplain shall be designed consistent with Chapter 18.775, Sensitive Lands. No residential structures are proposed. The proposed extension will not decrease the flood storage capacity because the construction will return the site to its original state upon completion. FINDING: Because the applicant has indicated that the site will be returned to its original state upon completion of the project, this standard has been satisfied. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106T"&JOHNSON PAGE 5 OF 12 Avoid steep slopes. Within 50 feet of any water resource, excavation and vegetation removal shall be avoided on slopes of 25% or greater and in areas with high erosion potential (as shown on SCS maps), except where necessary to construct public facilities or to ensure slope stability. This standard does not apply because the project is necessary to construct a public facility. FINDING: Because the project is necessary to construct a public facility, this standard does not apply. Minimize impacts on existing vegetation. The following standards shall apply when construction activity is proposed in areas where vegetation is to be preserved. Temporary measures used for initial erosion control shall not be left in place permanently; The applicant has stated that, upon completion, all temporary erosion control devices will be removed. Work areas on the immediate site shall be carefully identified and marked to reduce potential damage to trees and vegetation; The applicant has indicated, and a condition will be required insuring that prior to construction, the pipe alignment and work area will be staked and clearly marked. Trees shall not be used as anchors for stabilizing working equipment. During clearing operations, trees and vegetation shall not be permitted to fall or be placed outside the work area; The applicant has stated that no trees will be used for anchoring or stabilizing equipment and that trees will not be permitted to fall or be placed outside of the work area. The condition to clearly mark the work area will help to insure that this standard is met. In areas designated for selective cutting or clearing, care in falling and removing trees and brush shall be taken to avoid injuring trees and shrubs to be left in place; The applicant has stated that the utmost care will be taken during tree and vegetation removal to avoid injuring adjacent trees and vegetation. In addition, staff will require as a condition of approval that the applicant install construction fencing around trees that will not be removed in the work area to insure that they are protected. Stockpiling of soil, or soil mixed with vegetation, shall not be permitted on a permanent basis. The applicant states that there may be temporary stockpiling of material, however, there will be no permanent stockpiling of materials on-site. FINDING: Based on the analysis above, the applicant's plan indicates that the above standards will be satisfied provided that the following conditions are met. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 6 OF 12 CONDITIONS: The applicant shall install construction fencing around trees that will not be removed within the work area to insure that they are protected. Prior to construction, the pipe alignment and work area shall be staked and clearly marked. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Vegetation mitigation plan. If a Type II or III use is proposed within a water resource site or riparian setback area, or mitigation is proposed as a method to reduce the riparian setback in accordance with Section 18.797.100, a mitigation plan shall be prepared and implemented. The applicant shall be responsible for re-vegetating areas temporarily disturbed by excavation on a 1:1 basis; The applicant has indicated that re-vegetation will occur after the installation of the proposed sanitary sewer line. The re-vegetation will consist of re-seeding the areas disturbed by construction and will include off-site tree planting in a 1:1 basis. A condition of approval has been attached requiring the applicant to re-vegetate any disturbed areas after completion of the construction. The applicant stated that any additional planting requirements of the US Army Corps of Engineers permit approval will be incorporated into the plan prior to construction. Where approval is granted to reduce the riparian setback area, the applicant shall be responsible for mitigating for the reduced setback by replacing non-native vegetation within the remaining, protected riparian setback area on a 1.5:1 basis. That is, for each 100 square feet of riparian setback that is lost to development, at least 150 square feet of existing disturbed area within the riparian setback or wetland shall be re-planted with native plant species; The proposal does not request a reduction in the riparian setback area, therefore, this standard does not apply. The re-vegetation plan shall provide for the replanting and maintenance of native plant species designed to achieve pre-disturbance conditions. The applicant shall be responsible for replacing any native plant species that do not survive the first two years after planting, and for ensuring the survival of any replacement plants for an additional two years after their replacement. The applicant's re-vegetation plan provides for the replanting and maintenance of native plant species designed to achieve pre-disturbed conditions. The applicant has acknowledged responsibility for the replacement of plants that do not survive the first 2 years following construction and any replacement plants for an additional two years thereafter. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106T"&JOHNSON PAGE 7 OF 12 FINDING: Based on the analysis above, the applicant's plan indicates that the vegetation mitigation plan standards will be satisfied. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Water and sewer infiltration and discharge. Water and sanitary sewer facilities shall be designed, located and constructed to avoid infiltration of floodwaters into the system, and to avoid discharges from such facilities to streams and wetlands. The proposed sewer line has been designed using adopted City of Tigard, USA and American Public Works Association Design Standards. Because this is simply a line crossing the drainageway, infiltration of floodwaters and discharges into the stream and wetlands is unlikely. FINDING: Because the sanitary sewer line has been designed using appropriate design standards and the line itself is not likely to be discharged into stream and wetlands or be infiltrated with floodwaters, this standard has been satisfied. On-site systems. On-site septic systems and private wells shall be prohibited within the WR overlay district. No septic systems or private wells are proposed. FINDING: Because no septic systems or private wells are proposed for this project, this standard does not apply. Erosion control plan. If a Type II or III use is proposed within a water resource site or riparian setback area, the following erosion control standards shall apply within the WR overlay district: Specific methods of soil erosion and sediment control shall be used during construction to minimize visible and measurable erosion; The applicant has submitted an erosion control plan which will insure that visible and measurable erosion control measures will be in place. A condition will be attached requiring the erosion control measures be in place prior to construction and removed only after construction has been completed. The land area to be grubbed, stripped, used for temporary placement of soil, or to otherwise expose soil shall be confined to the immediate construction site only; The applicant has submitted an erosion control plan that shows the area of disturbance will be confined to the construction area. The condition to clearly mark the construction area will insure that this is further satisfied. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 8 OF 12 Construction activity will take place during the dry season (June-October), whenever feasible, and the duration of exposure of soils shall be kept to a minimum during construction; The applicant has indicated that construction will not begin until July of 1999 and is anticipated to be completed in August of 1999. The applicant has stated that trenches will be back-filled immediately after placement of pipe thus keeping exposure of soils to a minimum during construction. Exposed soils shall be covered by mulch, sheeting, temporary seeding or other suitable material following grading or construction, until soils are stabilized. During the rainy season (November through May), soils shall not be exposed for more than 7 calendar days. All disturbed land areas which will remain unworked for 21 days or more during construction, shall be mulched and seeded; The applicant has indicated that the exposed soils will be hydro-seeded immediately after construction and soil will be stabilized prior to the rainy season. During construction, runoff from the site shall be controlled, and increased runoff and sediment resulting from soil disturbance shall be retained on-site. Temporary diversions, sediment basins, barriers, check dams, or other methods shall be provided as necessary to hold sediment and runoff; The applicant has submitted an erosion plan that will insure that this standard will be met. In addition, the US Army Corp of Engineers permit and a condition of this approval will insure that erosion control measures are in place. A stabilized pad of gravel shall be constructed at all entrances and exists to the construction site. The stabilized gravel pad shall be the only allowable entrance or exit to the site; The applicant has stated that, with the exception of the creek crossing, all construction will occur on an existing paved surface, thus satisfying this standard. Topsoil removal for development shall be stockpiled and reused on-site to the degree necessary to restore disturbed areas to their original or enhanced condition, or to assure sufficient stable topsoil for re-vegetation. Additional soil shall be provided if necessary to support re-vegetation; The applicant's plans indicate that the topsoil removed will be reused to re-establish existing grades and support re-vegetation. The removal of all sediments which are carried into the streets, water resources or on to adjacent property, are the responsibility of the applicant. The applicant shall be responsible for cleaning up and repairing streets, catch basins, water resource areas and adjacent properties, where such properties are affected by sediments or mud. In no case shall sediments be washed into storm drains, ditches or drainageways; SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106T"&JOHNSON PAGE 9 OF 12 The applicant has proposed erosion control measures which will insure that sediments due to erosion are controlled on-site, however, the applicant will be responsible for the removal of any sediments carried into the street, water resources, or private property. The applicant has acknowledged this and this approval is based on this being the responsibility of the applicant. Any other relevant provisions of the Erosion Prevention and Sediment Control Plans Technical Guidance Handbook (City of Portland Bureau of Environmental Services and Unified Sewerage Agency of Washington County, Revised February 1994), required by the Planning Director. The plans have been designed using the standards above. The Director will not require any additional requirements. FINDING: Based on the analysis above, the applicant's plan indicates that the above standards will be satisfied. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Plan implementation. A schedule of planned erosion control and re-vegetation measures shall be provided, which sets forth the progress of construction activities, and mitigating erosion control measures. An approved Erosion Control of Re- vegetation Plan shall be implemented and maintained as follows: Erosion control measures shall be installed prior to any stripping or excavation work; The applicant shall implement the measures and construct facilities contained in the approved Erosion Control Plan in a timely manner. During active construction, the applicant shall inspect erosion control measures daily, and maintain, adjust, repair or replace erosion control measures to ensure that they are functioning properly; Eroded sediment shall be removed immediately from pavement surfaces, off-site areas, and from the surface water management system, including storm drainage inlets, ditches and culverts; Water containing sediment shall not be flushed into the surface water management system, wetlands or streams without first passing through an approved sediment filtering facility or device; In addition, the applicant shall call for City inspection, prior to the foundation inspection for any building, to certify that erosion control measures are installed in accordance with the erosion control plan. The applicant has submitted an erosion control plan that will insure the standards are met. A condition will be required that all erosion control measures be in place prior to beginning construction. FINDING: Based on the analysis above, the applicant's plan indicates that the above standards will be satisfied.

Based on the data presented, I concur with your conclusions The wetland area mapped in Figure 5 of your report is subject to permit requirements of the state Removal-Fill Law (ORS 196.800-196.990). A state permit is required for fill or excavation of 50 cubic yards or more in the wetland area. Per Bill Parks (DSL Permit Coordinator) letter of February 3, 1999, the 50 cubic yard threshold will not be exceeded and a state permit will not be required for the proposed work. Federal or local wetland permit requirements may apply. Division approval of wetland delineation reports is based upon the information provided to us. Should additional information be brought to our attention or should site conditions change, we would consider the new information and re-evaluate the site and our jurisdictional determination as needed. If you have any questions regarding the delineation review, please do not hesitate to contact me at (503) 378-3805 ext. 233. Sincerely, 1 11 adv.

APPLICATION SUMMARY CASE: CITY OF TIGARD SEWER EXTENSION NEAR 106TH & JOHNSON Sensitive Lands Review SLR 99-0001 PROPOSAL: The applicant is requesting Sensitive Lands Review approval and Water Resources Overlay approval to extend a sanitary sewer line across a drainageway and City inventoried wetlands in order to provide sewer service to homes in the area. APPLICANT: City of Tigard OWNER: City of Tigard Project Engineer: Letha Thomas 13125 SW Hall Boulevard 13125 SW Hall Boulevard Tigard, OR 97223 Tigard, OR 97223 COMPREHENSIVE PLAN DESIGNATION: Low Density Residential; 1-5 Dwelling Units Per Acre. ZONING DESIGNATION: Single-Family Residential - 7,500 Square Feet Per Unit, 4.5 Units Per Acre; R-4.5. The purpose of the R-4.5 Zoning District is to establish standard urban low-density residential sites. The R-4.5 zone allows, among other uses, single-family residential units, public support facilities, residential treatment homes, farming, manufactured homes, family day care, home occupations, temporary uses, residential fuel tank, and accessory structures. LOCATION: Deny Dell Creek is approximately 500 feet east of the intersection of SW 106' and SW Johnson Street. The proposed sanitary sewer line will cross the stream and continue west for approximately 400 linear feet along the centerline of SW Johnson Street where it will then connect to another sanitary sewer line at SW 106th Avenue. APPLICABLE REVIEW CRITERIA: Community Development Code Chapters 18.390, 18.775 and 18.797. SECTION II. DECISION Notice is hereby given that the Community Development Director's designee has APPROVED the above request subject to certain conditions of approval. The findings'and condusio on which the decision is based are noted in Section IV of this Decision. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 1 OF 12 CONDITIONS OF APPROVAL PRIOR TO CONSTRUCTION, THE FOLLOWING CONDITIONS SHALL BE SATISFIED: 1 . Submit a copy of the permit approval from the US Army Corps of Engineers or a letter from said agency indicating that a permit is not required. 2. Install erosion control measures prior to construction. Erosion control measures may not be removed until construction has been completed. 3. Upon completion of construction, the site shall be restored to its original state with natural vegetation and replacement of soil. THIS APPROVAL SHALL BE VALID FOR EIGHTEEN (18) MONTHS FROM THE EFFECTIVE DATE OF THIS DECISION. SECTION III. BACKGROUND INFORMATION Site History: The area of SW Johnson Street and SW 106`h Avenue was recently annexed into the City of Tigard so that city sewer services could be extended to serve the properties abutting these streets. Upon annexation a reimbursement district was formed which would allow the City to design and construct the sewer extension and then be reimbursed by the property owners. The sewer connection requires the crossing of Derry Dell Creek. Vicinity Information and Proposal Description: The sewer project is in an area zoned R-4.5. The sewer line will be extended across Derry Dell Creek, which is a minor stream on the Water Resources Overlay. There are City inventoried and jurisdictional wetlands within the area to be crossed. Because the proposal is to cross a drainageway, Sensitive Lands Review (SLR) approval is required. Because the drainageway is listed as a minor stream and identified on the City's inventory, Type II review is required for the Water Resources Overlay. SECTION IV. APPLICABLE REVIEW CRITERIA AND FINDINGS COMPLIANCE WITH COMMUNITY DEVELOPMENT CODE SECTIONS: SENSITIVE LANDS Section 18.775 states that the Director shall have the authority to issue a sensitive lands permit in the following areas by means of a Type II procedure, as governed in Section 18.390.040, using approval criteria contained in Section 18.775.070 C-E: • Drainageways; • Slopes that are 25% or greater or unstable ground; and • Wetland areas which are not regulated by other local, state, or federal agencies and are designated as significant wetlands on the Comprehensive Plan Floodplain and Wetland Map. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 2 OF 12 Drainageways. The appropriate approval authority shall approve, approve with conditions or deny an application request for a sensitive lands permit within drainageways based upon findings that all of the following criteria have been satisfied: The extent and nature of the proposed land form alteration or development will not create site disturbances to the extent greater than that required for the use; The site disturbances are the minimum necessary to install the sewer extension. In addition, the ground will be returned to its original state after the construction has been completed. The proposed land form alteration or development will not result in erosion, stream sedimentation, ground instability, or other adverse on-site and off-site effects or hazards to life or property; The applicant has submitted an erosion control plan that shows erosion control measures will be employed during the construction period. In addition, the US Army Corps of Engineers permit will regulate erosion control. The water flow capacity of the drainageway is not decreased; The proposed extension will not affect the water flow capacity of the drainageway because the alteration is temporary and the ground after construction will be restored to its original state. Where natural vegetation has been removed due to land form alteration or development, the areas not covered by structures or impervious surfaces will be replanted to prevent erosion in accordance with Chapter 18.745, Landscaping and Screening; The applicant's narrative states that natural vegetation will be replanted upon completion of the project. A condition of approval will be attached requiring the area to be restored to its original state upon completion of the sewer extension in this area. The drainageway will be replaced by a public facility of adequate size to accommodate maximum flow in accordance with the adopted 1981 Master Drainage Plan; The drainageway is not being replaced, therefore, this standard does not apply. The necessary U.S. Army Corps of Engineers and State of Oregon Land Board, Division of State Lands (DSL) approvals shall be obtained; The applicant has submitted for permit approval from DSL and the US Army Corps of Engineers. DSL has stated that the wetland delineation has been approved and no permits are required. The US Army Corps of Engineers has indicated that a permit is required but has not been approved yet. A condition of approval will be attached requiring that evidence of permit approval be submitted prior to the start of any construction within this area. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 3 OF 12 Where landform alterations and/or development are allowed within and adjacent to the 100-year floodplain, the City shall require the consideration of dedication of sufficient open land area within and adjacent to the floodplain in accordance with the Comprehensive Plan. This area shall include portions of a suitable elevation for the construction of a pedestrian/bicycle pathway within the floodplain in accordance with the adopted pedestrian bicycle pathway plan. The area of alteration is not within or adjacent to a floodplain, therefore, this standard does not apply. FINDING: Based on the analysis above, the applicant's plan will fully comply with the SLR standards for alteration in drainageways provided that the required permits are obtained from the US Army Corps of Engineers. CONDITION: Submit evidence of permit approval from the US Army Corps of Engineers or a letter from the appropriate representative at the US Army Corps of Engineers that permit approval is not required. WATER RESOURCES DEVELOPMENT STANDARDS (18.797.080) The following shall apply to all development, including native vegetation removal and excavation, within the WR overlay district. No application for a use identified in Section 18.797.050 shall be deemed complete until the applicant has addressed each of these standards in writing. Alternatives considered. Except for stream corridor enhancement, most Type II and III uses are expected to develop outside of water resource and riparian setback areas. Therefore, Type II and III development applications must carefully examine upland alternatives for the proposed use, and explain the reasons why the proposed development cannot reasonably occur outside of the water resource or riparian setback area. Due to the topography of the area, there are no alternate routes available to provide sanitary sewer service to the properties seeking service. Therefore, no other alternative could be considered. FINDING: Because the applicant has provided information indicating that no alternative location is available due to the topography necessary to provide sanitary sewer service to the properties, this criterion has been satisfied. Minimize siting impacts. The proposed use shall be designed, located and constructed to minimize excavation, loss of native vegetation, erosion, and adverse hydrological impacts on water resources. For Type II and III uses, the civil engineer with experience in water quality must certify that any adverse water quality impacts of the development proposal will be minimized consistent with best management practices; SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 4 OF 12 For all uses, the development shall be located as far from the water resource, and use as little of the water resource or riparian setback area, as possible, recognizing the operational needs of the proposed development. The applicant's narrative states that every attempt has been made to insure minimum impact to the water resources. The project has been designed under the supervision of a Civil Engineer licensed in Oregon, and any adverse impacts will be minimized consistent with the best management practices. Staff concurs that the proposal has been designed to minimize impacts as much as possible given that the crossing of Derry Dell Creek is necessary in this location. FINDING: Because the proposal was prepared by an Engineer utilizing best management practices and will minimize the impacts will be minimized as much as possible, this standard has been satisfied. Construction materials and methods. Where development within the riparian area is unavoidable, construction materials or methods used within the riparian setback area shall minimize damage to water quality and native vegetation. The applicant's narrative indicates that the proposed construction will follow adopted City of Tigard, Unified Sewerage Agency (USA), DSL and US Army Corps of Engineers materials and methods for work in wetland areas. Erosion control methods will insure that impact to the drainage during construction is minimized and vegetation removal will be limited to the work area and replaced after the project is completed. FINDING: Because the applicant has proposed methods which will insure that damage to the water quality and native vegetation will be minimized, this standard has been satisfied. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Minimize flood damage. Above-ground residential structures shall not be permitted within the WR overlay district, where such land is also within the 100-year floodplain. On-site flood storage capacity shall not decrease as a result of development. The cumulative effects of any proposed development shall not reduce flood storage capacity or raise base flood elevations on- or off-site. Any new commercial or industrial land development proposed within the 100-year floodplain shall be designed consistent with Chapter 18.775, Sensitive Lands. No residential structures are proposed. The proposed extension will not decrease the flood storage capacity because the construction will return the site to its original state upon completion. FINDING: Because the applicant has indicated that the site will be returned to its original state upon completion of the project, this standard has been satisfied. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 5 OF 12 Avoid steep slopes. Within 50 feet of any water resource, excavation and vegetation removal shall be avoided on slopes of 25% or greater and in areas with high erosion potential (as shown on SCS maps), except where necessary to construct public facilities or to ensure slope stability. This standard does not apply because the project is necessary to construct a public facility. FINDING: Because the project is necessary to construct a public facility, this standard does not apply. Minimize impacts on existing vegetation. The following standards shall apply when construction activity is proposed in areas where vegetation is to be preserved. Temporary measures used for initial erosion control shall not be left in place permanently; The applicant has stated that, upon completion, all temporary erosion control devices will be removed. Work areas on the immediate site shall be carefully identified and marked to reduce potential damage to trees and vegetation; The applicant has indicated, and a condition will be required insuring that prior to construction, the pipe alignment and work area will be staked and clearly marked. Trees shall not be used as anchors for stabilizing working equipment. During clearing operations, trees and vegetation shall not be permitted to fall or be placed outside the work area; The applicant has stated that no trees will be used for anchoring or stabilizing equipment and that trees will not be permitted to fall or be placed outside of the work area. The condition to clearly mark the work area will help to insure that this standard is met. In areas designated for selective cutting or clearing, care in falling and removing trees and brush shall be taken to avoid injuring trees and shrubs to be left in place; The applicant has stated that the utmost care will be taken during tree and vegetation removal to avoid injuring adjacent trees and vegetation. In addition, staff will require as a condition of approval that the applicant install construction fencing around trees that will not be removed in the work area to insure that they are protected. Stockpiling of soil, or soil mixed with vegetation, shall not be permitted on a permanent basis. The applicant states that there may be temporary stockpiling of material, however, there will be no permanent stockpiling of materials on-site. FINDING: Based on the analysis above, the applicant's plan indicates that the above standards will be satisfied provided that the following conditions are met. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 6 OF 12 CONDITIONS: The applicant shall install construction fencing around trees that will not be removed within the work area to insure that they are protected. Prior to construction, the pipe alignment and work area shall be staked and clearly marked. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Vegetation mitigation plan. If a Type II or Ill use is proposed within a water resource site or riparian setback area, or mitigation is proposed as a method to reduce the riparian setback in accordance with Section 18.797.100, a mitigation plan shall be prepared and implemented. The applicant shall be responsible for re-vegetating areas temporarily disturbed by excavation on a 1:1 basis; The applicant has indicated that re-vegetation will occur after the installation of the proposed sanitary sewer line. The re-vegetation will consist of re-seeding the areas disturbed by construction and will include off-site tree planting in a 1:1 basis. A condition of approval has been attached requiring the applicant to re-vegetate any disturbed areas after completion of the construction. The applicant stated that any additional planting requirements of the US Army Corps of Engineers permit approval will be incorporated into the plan prior to construction. Where approval is granted to reduce the riparian setback area, the applicant shall be responsible for mitigating for the reduced setback by replacing non-native vegetation within the remaining, protected riparian setback area on a 1.5:1 basis. That is, for each 100 square feet of riparian setback that is lost to development, at least 150 square feet of existing disturbed area within the riparian setback or wetland shall be re-planted with native plant species; The proposal does not request a reduction in the riparian setback area, therefore, this standard does not apply. The re-vegetation plan shall provide for the replanting and maintenance of native plant species designed to achieve pre-disturbance conditions. The applicant shall be responsible for replacing any native plant species that do not survive the first two years after planting, and for ensuring the survival of any replacement plants for an additional two years after their replacement. The applicant's re-vegetation plan provides for the replanting and maintenance of native plant species designed to achieve pre-disturbed conditions. The applicant has acknowledged responsibility for the replacement of plants that do not survive the first 2 years following construction and any replacement plants for an additional two years thereafter. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 7 OF 12 FINDING: Based on the analysis above, the applicant's plan indicates that the vegetation mitigation plan standards will be satisfied. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Water and sewer infiltration and discharge. Water and sanitary sewer facilities shall be designed, located and constructed to avoid infiltration of floodwaters into the system, and to avoid discharges from such facilities to streams and wetlands. The proposed sewer line has been designed using adopted City of Tigard, USA and American Public Works Association Design Standards. Because this is simply a line crossing the drainageway, infiltration of floodwaters and discharges into the stream and wetlands is unlikely. FINDING: Because the sanitary sewer line has been designed using appropriate design standards and the line itself is not likely to be discharged into stream and wetlands or be infiltrated with floodwaters, this standard has been satisfied. On-site systems. On-site septic systems and private wells shall be prohibited within the WR overlay district. No septic systems or private wells are proposed. FINDING: Because no septic systems or private wells are proposed for this project, this standard does not apply. Erosion control plan. If a Type II or III use is proposed within a water resource site or riparian setback area, the following erosion control standards shall apply within the WR overlay district: Specific methods of soil erosion and sediment control shall be used during construction to minimize visible and measurable erosion; The applicant has submitted an erosion control plan which will insure that visible and measurable erosion control measures will be in place. A condition will be attached requiring the erosion control measures be in place prior to construction and removed only after construction has been completed. The land area to be grubbed, stripped, used for temporary placement of soil, or to otherwise expose soil shall be confined to the immediate construction site only; The applicant has submitted an erosion control plan that shows the area of disturbance will be confined to the construction area. The condition to clearly mark the construction area will insure that this is further satisfied. SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 8 OF 12 Construction activity will take place during the dry season (June-October), whenever feasible, and the duration of exposure of soils shall be kept to a minimum during construction; The applicant has indicated that construction will not begin until July of 1999 and is anticipated to be completed in August of 1999. The applicant has stated that trenches will be back-filled immediately after placement of pipe thus keeping exposure of soils to a minimum during construction. Exposed soils shall be covered by mulch, sheeting, temporary seeding or other suitable material following grading or construction, until soils are stabilized. During the rainy season (November through May), soils shall not be exposed for more than 7 calendar days. All disturbed land areas which will remain unworked for 21 days or more during construction, shall be mulched and seeded; The applicant has indicated that the exposed soils will be hydro-seeded immediately after construction and soil will be stabilized prior to the rainy season. During construction, runoff from the site shall be controlled, and increased runoff and sediment resulting from soil disturbance shall be retained on-site. Temporary diversions, sediment basins, barriers, check dams, or other methods shall be provided as necessary to hold sediment and runoff; The applicant has submitted an erosion plan that will insure that this standard will be met. In addition, the US Army Corp of Engineers permit and a condition of this approval will insure that erosion control measures are in place. A stabilized pad of gravel shall be constructed at all entrances and exists to the construction site. The stabilized gravel pad shall be the only allowable entrance or exit to the site; The applicant has stated that, with the exception of the creek crossing, all construction will occur on an existing paved surface, thus satisfying this standard. Topsoil removal for development shall be stockpiled and reused on-site to the degree necessary to restore disturbed areas to their original or enhanced condition, or to assure sufficient stable topsoil for re-vegetation. Additional soil shall be provided if necessary to support re-vegetation; The applicant's plans indicate that the topsoil removed will be reused to re-establish existing grades and support re-vegetation. The removal of all sediments which are carried into the streets, water resources or on to adjacent property, are the responsibility of the applicant. The applicant shall be responsible for cleaning up and repairing streets, catch basins, water resource areas and adjacent properties, where such properties are affected by sediments or mud. In no case shall sediments be washed into storm drains, ditches or drainageways; SLR 99-0001 CITY OF TIGARD SEWER LINE EXTENSION NEAR 106TH&JOHNSON PAGE 9 OF 12 The applicant has proposed erosion control measures which will insure that sediments due to erosion are controlled on-site, however, the applicant will be responsible for the removal of any sediments carried into the street, water resources, or private property. The applicant has acknowledged this and this approval is based on this being the responsibility of the applicant. Any other relevant provisions of the Erosion Prevention and Sediment Control Plans Technical Guidance Handbook (City of Portland Bureau of Environmental Services and Unified Sewerage Agency of Washington County, Revised February 1994), required by the Planning Director. The plans have been designed using the standards above. The Director will not require any additional requirements. FINDING: Based on the analysis above, the applicant's plan indicates that the above standards will be satisfied. Note: The applicant, by submitting a proposal to comply with these standards, accepts responsibility in insuring that the proposed methods are utilized during construction. If construction activities do not comply with the standards specified, the applicant is responsible. Plan implementation. A schedule of planned erosion control and re-vegetation measures shall be provided, which sets forth the progress of construction activities, and mitigating erosion control measures. An approved Erosion Control of Re- vegetation Plan shall be implemented and maintained as follows: Erosion control measures shall be installed prior to any stripping or excavation work; The applicant shall implement the measures and construct facilities contained in the approved Erosion Control Plan in a timely manner. During active construction, the applicant shall inspect erosion control measures daily, and maintain, adjust, repair or replace erosion control measures to ensure that they are functioning properly; Eroded sediment shall be removed immediately from pavement surfaces, off-site areas, and from the surface water management system, including storm drainage inlets, ditches and culverts; Water containing sediment shall not be flushed into the surface water management system, wetlands or streams without first passing through an approved sediment filtering facility or device; In addition, the applicant shall call for City inspection, prior to the foundation inspection for any building, to certify that erosion control measures are installed in accordance with the erosion control plan. The applicant has submitted an erosion control plan that will insure the standards are met. A condition will be required that all erosion control measures be in place prior to beginning construction. FINDING: Based on the analysis above, the applicant's plan indicates that the above standards will be satisfied.

Application for Water Resources Overlay Distract Permit • • • • SW 1061h Ave & SW Johnson St Sanitary Sewer Extension Application for Water Resources Overlay Permit Introduction The proposed sanitary sewer extension project is located on SW 106th Avenue and SW Johnson Street in the City of Tigard, West of Deny Dell Creek (Township 2 South,Range 1 West, Section 3)(Figure 1). Deny Dell Creek is considered a minor stream by the City of Tigard (City) and is mapped within the Water Resources Overlay District as a Significant Water Resource in the Tigard Planning Area. Because the proposed sewer will cross Deny Dell Creek, Section 18.85 Water Resources Overlay District applies to the proposed project. Proposed Project Description The sanitary sewer extension project is proposed to provide service to the surrounding property owners. In recent years, especially during periods of rainy seasons, existing septic systems have experienced capacity constraints and/or are in the process of failing. Property owners to receive service have recently annexed to the City in order to take part of the City's Neighborhood Sewer Extension Program. The closest existing sewer is a 15"line adjacent to Deny Dell Creek. It has adequate capacity and is at an ideal location to provide service to the subject properties. The proposed sewer extension is within the existing Right of Way of the City. An 8" sewer line will be connected to the existing 15"sewer,will cross Derry Dell Creek and run 353'west on SW Johnson Street to a manhole at the intersection of SW 106th Avenue. The line will then extend 70'north on SW 106th Avenue terminating at a cleanout. The line will also extend 206'south on SW 106th Avenue terminating at a manhole. The project will provide service for nine properties(Exhibit A). There is no other available connection point that would be able to provide sanitary sewer service for the subject properties. The City has hired Pacific Habitat Services to provide a wetland delineation report, and to obtain the required U.S.Army Corps of Engineers and State of Oregon Division of State Lands permits(Exhibit B). Construction is scheduled to conform to the seasonal constraints of these permits. Erosion Control During construction the applicant shall conform to applicable erosion control criteria and Unified Sewerage Agency Standards. 2 Upon completion of the project, all existing ground elevations shall be re- established. All disturbed areas within the wetland boundary shall be re-seeded as • specified in the wetland mitigation plan prepared by Pacific Habitat Services consultants. Significant trees unavoidably removed by construction will be mitigated off site. 18.85.00 Water Resources Overlay District 18.85.60 Application Requirements for a Type II Use (A) Type I Uses. Response: Not applicable. The proposed project is not a Type I Use (B) Type II and III Uses: Site Specific Survey Required Response: A full set of drawings is included with this application, this information is shown in Exhibit A. (C) Site Specific Water Resource and Riparian Setback Determinations Response: A wetland Delineation Report was completed by Pacific Habitat Services, Inc. in January 1999. The wetland/water resource boundary was surveyed. This information is included in Exhibit B. (D) Type II and III Uses: Required Studies and Mitigation Reports Response: Refer to Exhibits A and B. Conclusion Based on the analysis of the Water Resources Overlay District issues and the City of Tigard's development goals,the proposal is in compliance with the City's Comprehensive plan. 3 I nom !r''� I `````\ C I T Y of T I G A R D ��`'` ■� GEOGRAPHIC INFORMATION SYSTEM .. `:, —r Figure 1 • ; � 'r `‘ _; _ , Vicinity Map •SIITAV/ ■v ` SW 106th Ave&SW Johnson St — ��� Sanitary Sewer Extension .c, r , 1mi ..... ��� ( February 1999 AOCAT'ON JECT ; ,��\�\� .��\% ��`.z._.r i)( 'N\ i awn TL r r 1 ` \\` 1 WALNUT ` / '1/ i \\\`t 1111 r Al 0./ / +11� F I I I � a / N' / s+�/ 1 i AL .'

(PHS) conducted a wetland determination and delineation on the site of a proposed sanitary sewer line extension along SW 106th Avenue and SW Johnson Street in Tigard, Oregon(Township 2 South, Range 1 West, Section 2). The site is located north of SW Walnut Street, southeast of SW Tiedeman Avenue, and west of Pacific Highway- 99W. The generalized location is shown in Figure 1. The study area for the delineation is located at the eastern end of the proposed sewer line extension, from the eastern end of SW Johnson Street, to an existing sewer line in an open field on the east side of a northerly flowing stream. This report presents the definitions and the methodology used to determine the location and extent of wetland and waters of the state along the eastern end of the proposed route, followed by a discussion of site characteristics as they pertain to the three required wetland criteria. Also included are the proposed sewer line alignment, proposed impacts to wetland and waters of the state, and mitigation and restoration to compensate for the proposed impacts. The wetland delineation was conducted on November 24, 1998. 2.0 WATERS OF THE STATE AND WETLAND DEFINITION AND CRITERIA 2.1 Regulatory Jurisdiction Wetlands and water resources in Oregon are regulated by the Oregon Division of State Lands (DSL) under the Removal-Fill Law (ORS 196.800-196.990) and by the US Army Corps of Engineers (COE) through Section 404 of the Clean Water Act. The primary source document for wetland delineations within Oregon is the Corps of Engineers Wetlands Delineation Manual, Technical Report Y-87-1 (Environmental Laboratory 1987)which is recognized by both DSL and COE. 2.2 Waters of the State and Wetland Definition Waters of the state are defined as "natural waterways including all tidal and nontidal bays, intermittent streams, constantly flowing streams, lakes, wetlands and other bodies of water in this state, navigable and nonnavigable...". "Natural waterways"is further defined as waterways created naturally by geological and hydrological processes, waterways that would be natural but for human-caused disturbances (e.g. channelized or culverted streams, impounded waters, partially drained wetlands or ponds created in wetlands)..."(DSL, 1995). A wetland is defined as "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" (DSL, 1995).

Location and general topo of a proposed sanitary sewer line extension along SW 106th Avenue and SW Johnson Street in Tigard, Oregon (U.S.G.S., Beaverton, OR, 7.5 minute quadrangle, 1961 photorevised 1984). ' 2.3 Wetland Criteria Based on the above definition, three major factors characterize a wetland: hydrology, substrate, and biota. 2.3.1 Wetland Hydrology Wetland hydrology is related to duration of saturation, frequency of saturation, and critical depth of saturation. The 1987 manual defines wetland hydrology as inundation or saturation within a major portion of the root zone (usually above 12 inches), typically for at least 12.5% of the growing season. The wetland hydrology criterion can be met, however, if saturation within the major portion of the root zone is present for only 5% of the growing season, depending on other evidence. The growing season is defined as the portion of the year when soil temperatures at 19.7 inches below the soil surface are higher than biological zero (41 degrees Fahrenheit, 5 degrees Celsius), but also allows approximation from frost free days, based on air temperature. The growing season for any given site or location is determined from United States Department of Agriculture (USDA), Natural Resources Conservation Service(NRCS) (formerly USDA, Soil Conservation Service (SCS))data and information. Wetland hydrologic indicators include the following: visual observation of inundation or saturation,watermarks, drift lines, sediment deposits, drainage pattern, and/or oxidized rhizospheres with living roots. Oxidized rhizospheres are defined as yellowish-red zones around the roots and rhizomes of some plants which grow in frequently saturated soils. 2.3.2 Wetland Substrate(Soils) Most wetlands are characterized by hydric soils. Hydric soils are those that are ponded, flooded, or saturated for long enough during the growing season to develop anaerobic conditions. Periodic saturation of soils causes alternation of reduced and oxidized conditions which leads to the formation of redoximorphic features (gleying and mottling). Mineral hydric soils will be either gleyed or will have bright mottles and/or low matrix chroma. The redoximorphic feature known as gley is a result of greatly reduced soil conditions which result in a characteristic grayish, bluish or greenish soil color. The term mottling is used to describe areas of contrasting color within a soil matrix. The soil matrix is the portion of the soil layer that has the predominant color. Soils which have brightly colored mottles and a low matrix chroma are indicative of a fluctuating water table. Hydric soil indicators include: organic content of greater than 50%by volume, sulfidic material or"rotten egg"odor, and/or presence of redoximorphic features and dark soil matrix, as determined by the use of a Munsell Soil Color Chart. This chart establishes the chroma, value and hue of soils based on comparison with color chips. Mineral hydric soils usually have a matrix chroma of 2 or less in mottled soils, or a matrix chroma of 1 or less in unmottled soils. Pacific Habitat Services, Inc. -2- 2.3.3 Wetland Biota (Vegetation) Wetland biota is defined as hydrophytic vegetation. A hydrophyte is a plant species that is capable of growing in substrates that are periodically deficient in oxygen as a result of saturated soil conditions. The US Fish and Wildlife Service, in the National List of Plant Species that Occur in Wetlands, has established five basic groups of vegetation based on their frequency of occurrence in wetlands. These categories, referred to as the "wetland indicator status", are as follows: obligate wetland plants (OBL), facultative wetland (FACW), facultative (FAC), facultative upland (FACU), and obligate upland (UPL). Indicator Code Status _ OBL Obligate wetland. Estimated to occur almost exclusively in wetlands (>99%) FACW Facultative wetland. Estimated to occur 67-99%of the time in wetlands. FAC Facultative. Occur equally in wetlands and non-wetlands (34-66%). FACU Facultative upland. Usually occur in non-wetlands (67-99%). UPL Obligate upland. Estimated to occur almost exclusively in non-wetlands (>99%). If a species is not assigned to one of the four groups described above it is assumed to be obligate upland. NI Has not yet received a wetland indicator status, but is probably not obligate upland. 3.0 PROJECT METHODOLOGY 3.1 Off-Site Research Prior to beginning field work, available information was reviewed in order to ascertain where potential wetland/waters of the state may exist on-site, and to facilitate the gathering of data. This review included the USGS topographic quadrangle, the Soil Conservation Service soil series maps, the list of Oregon hydric soils by County, the US Fish and Wildlife Service (USFWS)National Wetlands Inventory(NWI)map, and the Local Wetlands Inventory(LWI) map for the site. 3.2 Wetland Delineation Field Methodology Observations of hydrology, soils, and vegetation, were made using the "Routine On-site" delineation method as defined in the 1987 manual. One-foot diameter soil pits were excavated up to a depth of 18 inches in selected locations. The soil profiles were examined for hydric soil and wetland hydrology field indicators. Pacific Habitat Services, Inc. -3 - In addition, a visual percent-cover estimate of the dominant species of the plant community was performed using soil pit locations as a center of reference. Dominant plant species are based on estimates of percent cover for herbaceous, woody vine, and shrub species within a 5 foot radius of the sample point, and basal area cover for tree species within a 30 foot radius of the sample point. Plant species in each vegetative layer which are estimated at less than 20% are not considered to be dominant. The wetland indicator status is then used to determine if there is an overall dominance (greater than 50%) of wetland or upland plant species. Data documenting the three criteria for the representative sample locations are recorded in the field. This information is subsequently transferred to standard wetland delineation data sheets, which are included in Appendix A. In addition to the sample points, numerous other soil pits were excavated between the data points to verify changes in the three criteria. 4.0 WETLAND CRITERIA DISCUSSION 4.1 Topography The study area is relatively level,with site elevations ranging from approximately 150 to 155 feet National Geodetic Vertical Datum (NGVD). A channelized stream which flows to the north is located at the eastern end of the proposed sewer line extension. The stream flows into Fanno Creek, approximately 0.14 mile north of the site. The eastern end of SW Johnson Street and associated residential development, end at the western bank of the stream. The top of the eastern bank lies a few feet below the western bank and extends into an open field. 4.2 Hydrology The dominant hydrologic feature within the study area is the channelized stream that flows north towards Fanno Creek. Other factors that influence the site hydrologically include direct precipitation and storm water runoff from surrounding residential development to the west. The open field on the east side of the stream is slightly lower in elevation and subject to groundwater fluctuations associated with the stream. The hydrology criterion for jurisdictional wetland was satisfied along the east side of the stream by the presence of sulfidic odor, a shallow water table, soils saturated to the surface, active oxidized rhizospheres, evidence of ponding, and wetland drainage patterns. 4.3 Soils The US Department of Agriculture, Natural Resources Conservation Service (NRCS) (formerly, Soil Conservation Service (SCS)) has mapped the site as having Cove silty clay loam (map unit 13), and Woodburn silt loam, 3 to 7% slopes (map unit 45B). Only the Cove soil is considered to be hydric by the NRCS (USDA, SCS, 1989), however, the Woodburn series does contain hydric soil inclusions (Figure 2). Cove soils consist of poorly drained soils that formed in recent clayey alluvium on floodplains. In a representative profile, the surface layer is very dark gray, mottled silty clay loam about 8 inches thick. The subsoil is very dark gray, gleyed and mottled clay about 32 Pacific Habitat Services, Inc. -4- ■ Pacific Habitat Services, Inc.

The substratum is very dark gray clay that extends to a depth of 60 inches or more. Permeability is very slow. This soil is classified as a fine, montmorillonitic, mesic Vertic Haplaquoll. The Woodburn series consists of moderately well-drained soils that formed in old alluvium on low,broad valley terraces. In a representative profile, the surface layer is very dark grayish- brown silt loam about 11 inches thick. The subsoil is dark-brown and dark grayish-brown silt loam and silty clay loam about 30 inches thick. The substratum is dark grayish-brown silt loam about 19 inches thick. Permeability is slow. This soil is classified as a fine-silty, mixed, mesic Aquultic Argixeroll. Most of the soils observed on the west side of the stream were somewhat disturbed, which is likely due to the construction of SW Johnson Street. In contrast, the soils observed on the east side more closely resembled a native soil profile. Soils on the west side of the stream were very dark grayish-brown(10YR 3/2) silt loams without mottles, and those on the east side included very dark gray(10YR 3/1) and very dark grayish-brown silt loams with distinct mottles. The hydric soils criterion was satisfied along the east side of the stream, by the presence of sulfidic odor,and low chroma soils, both with and without mottles. 4.4 Vegetation The west side of the stream lacks any notable vegetation,with the exception of five mature black cottonwood (Populus trichocarpa, FAC)trees. The east side of the stream primarily consists of an open field dominated by herbaceous species including creeping bentgrass (Agrostis stolonifera, FACW), rice cutgrass (Leersia oryzoides, OBL), creeping buttercup (Ranunculus repens, FACW),reed canarygrass(Phalaris arundinacea, FACW), soft rush (Juncus effusus, FACW),meadow foxtail (Alopecurus pratensis, FACW), and American speedwell (Veronica americana, OBL). Also present along the eastern bank are Himalayan blackberry thickets (Rubus discolor, FACU) and an isolated red-osier dogwood (Corpus stolonifera, FACW). The hydrophytic vegetation criterion was satisfied on the east side of the stream by the presence of a dominance of wetland plant species (plants with a wetland indicator status of FAC, FAC+,FACW-, FACW, FACW+, or OBL). 5.0 WATERS OF THE STATE AND WETLAND DISCUSSION & CONCLUSIONS 5.1 National and Local Wetlands Inventory The US Fish and Wildlife Service, as part of the National Wetlands Inventory(NWI) program, has mapped palustrine forested, broad-leaved deciduous, saturated, semipermanent, seasonal (PFO1Y)wetland within the study area(Figure 3). The NWI maps are generated primarily on the basis of interpretation of color infrared aerial photographs (scale of 1:58,000), with limited"ground truthing"to confirm the interpretations.

National Wetlands Inventory information for a proposed sanitary sewer line extension along SW 106th Avenue and SW Johnson Street in Tigard, Oregon (I1.S.F.W.5.,1981). The City of Tigard's Local Wetlands Inventory (LWI) has also mapped wetland, associated with a tributary of Fanno Creek, within the study area(Figure 4). PHS has identified an area of wetland along the east side of the stream, which is consistent with the NWI and LWI mappings. 5.2 Waters of the State and Wetland Conclusions Based on an investigation of the three required wetland criteria(wetland hydrology, hydric soils, and a dominance of hydrophytic vegetation), PHS has identified areas of potentially jurisdictional wetland and waters of the state along the eastern end of the proposed sewer line extension. The wetland area is located along the east side of a stream channel and extends further to the east,beyond the study area. The stream itself is considered waters of the state. Figure 5 shows the locations of potentially jurisdictional wetland, waters of the state, the proposed sewer line extension, and sample points within the study area. This delineation does not become jurisdictional until DSL and COE review and approve our assessment. 6.0 PROJECT DESCRIPTION 6.1 Proposed Sanitary Sewer Alignment The City of Tigard proposes to extend a sanitary sewer line from an existing sewer line located east of SW Johnson Street to SW 106th Avenue, which is located at the west end of SW Johnson Street. Population growth has put increasing demands on existing sewer lines; the proposed extension will provide greater efficiency. The proposed sanitary sewer line extension will consist of an 8-inch diameter pipe that will connect to an existing sanitary sewer line in an open field on the east side of the stream. The proposed sewer line will cross the stream, and continue west for approximately 400 linear feet along the center line of SW Johnson Street, where it will then connect to another sanitary sewer line at SW 106th Avenue. The sewer alignment along the stream crossing at the eastern end of the route, will temporarily utilize dams, such as cofferdams. The cofferdams will be temporarily placed into the stream channel in order to aid in the construction of the trench, and the alignment of the sewer line pipe. During this time, water on the upstream side of the trench will be piped around the trench and back into the stream, on the downstream side of the trench. A maximum two-foot wide by two-foot deep trench will be excavated for approximately four feet across the stream channel. All in-water work will be conducted during the Oregon Department of Fish and Wildlife's recommended in-water work period (June 1 - September 30). The remaining sewer alignment, approximately nineteen feet in length and to the east of the stream crossing, will consist of a two-foot wide by four and a half-foot deep trench.

Figure 6 shows the location of the proposed sewer line extension. Figures 7 and 8 illustrate a typical cross section of the sewer alignment, and a cross section of the stream crossing, respectively. 6.2 Proposed Wetland Impacts The proposed sewer line extension will temporarily impact approximately 38 square feet of low quality wetland, dominated by pasture grasses, on the east side of the stream. It will also impact approximately 8 square feet of waters of the state, by crossing the stream at the eastern end of the proposed extension. The proposed impacts to wetland and waters of the state will be minimal, approximately 46 square feet (approximately 0.001 acre), involving cut and fill procedures that will require restoration. In addition, the proposed sewer line will require the removal of two mature cottonwood trees from an upland buffer on the western bank of the stream. Figure 9 shows the locations of the proposed impacts. The proposed impacts are unavoidable due to the location of the existing sewer hook up points, and the lack of adequate open space between the trees. The proposed sewer line makes use of an existing sewer line trunk located along the east side of the stream. In addition, the proposed sewer line satisfies the Unified Sewerage Agency's (USA) sanitary sewer alignment and uniform grading requirements. The pipeline was aligned to minimize impacts to wetlands, waterways, and trees, as well as provide the necessary gradient for the sewer line. 7.0 WETLAND MITIGATION AND RESTORATION During the sewer line construction,proper preservation, restoration and clean-up protocols will be followed. For example, the excavated material will be stored adjacent to the trench, and the contractor will replace topsoil (with a minimum finished depth of 12 inches) over all trenches. In addition, sufficient erosion control methods, such as silt barriers, will be employed, and impact to the drainageway will be temporary, with restoration of streambed structure within the channel crossing. 7.1 Proposed Wetland Mitigation The wetland in the eastern end of the proposed sewer line extension is primarily composed of a mixture of pasture grasses, and therefore, restoration by soil replacement and reseeding to prevent erosion should be appropriate for this area. Since the proposed impacts are temporary, and no trees or shrubs will be removed from the wetland, mitigation will not be required for the activities proposed within this area.

Locations of proposed impacts to wetland and waters of the state for a proposed sanitary sewer line extension along SW 106th Avenue and SW Johnson Street in Tigard, Oregon (base map provided by City of Tigard, Oregon, 1998). The two trees to be removed along the western bank of the stream are not in wetland, however, the City of Tigard does require mitigation at a ratio of 1:1 (per diameter) for the trees. The trees to be removed are a 16-inch diameter breast-height (dbh) and a 32-inch dbh black cottonwood. Therefore, a total of 48-inches in diameter worth of trees will need to be planted. The City of Tigard is proposing to plant two thousand trees in 1999, a portion of which will satisfy the mitigation required for the removal of the two cottonwood trees during the construction of the proposed sanitary sewer line extension. The portion of trees to be planted as mitigation for the proposed sewer line extension will be installed at Cook Park in Tigard, Oregon. The plantings will include native species such as Douglas' hawthorn (Crataegus douglasii, FAC), willow (Salix spp., FAC-FACW), and red- osier dogwood. 8.0 PROJECT SUMMARY • The proposed sanitary sewer line extension is located along SW 106th Avenue and SW Johnson Street,north of SW Walnut Street, southeast of SW Tiedeman Avenue, and west of Pacific Highway-99W in Tigard, Oregon(Township 2 South, Range 1 West, Section 2). • The proposed sanitary sewer line extension will connect to an existing sanitary sewer line in an open field on the east side of a stream. The proposed sewer line will cross the stream, and continue west along the center line of SW Johnson Street, where it will then connect to another sanitary sewer line at SW 106th Avenue. • Areas of potentially jurisdictional wetland and waters of the state are present along the eastern end of the proposed sewer line extension. • The proposed sewer line extension will temporarily impact approximately 38 square feet of low quality wetland, and approximately 8 square feet of waters of the state. In addition, it will also require the removal of two mature cottonwood trees from an upland buffer along the western bank of the stream. These impacts are unavoidable due to the location of the existing sewer hook up points, and the lack of adequate open space between the trees. • The proposed impacts to wetland and waters of the state will be minimal, approximately 46 square feet(approximately 0.001 acre), involving cut and fill procedures that will require restoration. Impact to the drainageway will be temporary, with restoration of streambed structure within the channel crossing. • Mitigation for the proposed wetland impact will consist of restoration by soil replacement and reseeding. Mitigation for the removal of the two trees from the upland buffer will be satisfied by a portion of the City of Tigard's planting of two thousand trees in 1999. The portion of trees which will satisfy the required mitigation will be installed at Cook Park in Tigard, Oregon, and will consist of native species.

Is the project site near a Wild and Scenic River? 0 Yes • No PROPOSED PROJECT PURPOSE & DESCRIPTION Project Purpose and Need: The City of Tigard proposes to extend a sanitary sewer line from an existing sewer line located east of SW Johnson Street to SW 106th Avenue, which is located at the west end of SW Johnson St. Population growth has put increasing demands on existing sewer lines; the proposed extension will provide greater efficiency. Project Description: The proposed sanitary sewer line extension will consist of an 8-inch diameter pipe that will connect to an existing sanitary sewer line in an open field on the east side of the stream. The proposed sewer line will cross the stream, and continue west for approximately 400 linear feet along the center line of SW Johnson Street, where it will then connect to another sanitary sewer line at SW 106th Avenue. The sewer alignment along the stream crossing at the eastern end of the route will temporarily utilize dams, such as cofferdams. The cofferdams will be temporarily placed into the stream channel in order to aid in the construction of the trench and the alignment of the sewer line pipe. During this time, water on the upstream side of the trench will be piped around the trench and back into the stream, on the downstream side of the trench. A maximum two-foot wide by two-foot deep trench will be excavated for approximately four feet across the stream channel. All in-water work will be conducted during the Oregon Department of Fish and Wildlife's recommended in-water work period (June 1 - September 30). The remaining sewer alignment, approximately nineteen feet in length, and to the east of the stream crossing, will consist of a two-foot wide by four and a half-foot deep trench.

The proposed sewer line extension will temporarily impact approximately 38 square feet of low quality wetland, dominated by pasture grasses, on the east side of the stream. It will also impact approximately 8 square feet of waters of the state, by crossing the stream at the eastern end of the proposed extension. The proposed impacts to wetland and waters of the state will be minimal, approximately 46 square feet (approximately 0.001 acre), involving cut and fill procedures that will require restoration. In addition, the proposed sewer line will require the removal of two mature cottonwood trees from an upland buffer on the western bank of the stream. The proposed impacts are unavoidable due to the location of the existing sewer hook up points, and the lack of adequate open space between the trees. The proposed sewer line makes use of an existing sewer line trunk located along the east side of the stream. In addition, the proposed sewer line satisfies the Unified Sewerage Agency's (USA) sanitary sewer alignment and uniform grading requirements. The pipeline was aligned to minimize impacts to wetlands, waterways, and trees, as well as provide the necessary gradient for the sewer line. Described what measures you will use (before and after construction) to minimize impacts to the waterway or wetland. During the sewer line construction proper preservation, restoration, and clean-up protocols will be followed. For example, the excavated material will be stored adjacent to the trench, and the contractor will replace topsoil (with a minimum finished depth of 12 inches) over all trenches. In addition, sufficient erosion control methods, such as silt barriers, will be employed. Impact to the drainageway will be temporary, with restoration of streambed structure within the channel crossing. All in-water work will be conducted during the Oregon Department of Fish and Wildlife's recommended in-water work period (June 1 - September 30).

SUPPLEMENTAL WETLAND IMPACT INFORMATION* (For Wetland Fills Only) Site Conditions of impact area Impact area is 0 Ocean 0 Estuary O River O Lake • Stream • Freshwater Wetland Note: Estuarian Resource Replacement is required by state law for projects involving intertidal or tidal marsh alterations. A separate Wetlands Resource Compensation Plan may be appended to the application. Has a wetland delineation been completed for this site? • Yes 0 No If yes, by whom: Pacific Habitat Services, inc. Describe the existing Physical and biological character of the wetland/waterway site by area and type of resource(use separate sheets and photos, if necessary) The project site is relatively level, with elevations ranging from approximately 150 to 155 feet National Geodetic Vertical Datum (NGVD). A channelized stream which flows to the north is located at the eastern end of the proposed sewer line extension. The stream flows into Fanno Creek, approximately 0.14 mile north of the site. The eastern end of SW Johnson Street and associated residential development, end at the western bank of the stream. The top of the eastern bank lies a few feet below the western bank and extends into an open field. The dominant hydrologic feature within the study area is the channelized stream that flows north towards Fanno Creek. Other factors that influence the site hydrologically include direct precipitation and storm water runoff from surrounding residential development to the west. The open field on the east side of the stream is slightly lower in elevation and subject to groundwater fluctuations associated the stream. The west side of the stream lacks any notable vegetation, with the exception of five mature black cottonwood trees. The east side of the stream primarily consists of an open field dominated by herbaceous species, including meadow foxtail, creeping bentgrass, creeping buttercup, and reed canarygrass. Also present along the eastern bank are Himalayan blackberry thickets and an isolated red-osier dogwood. Resources Replacement Mitigation Describe measures to be taken to replace unavoidably impacted wetland resources The wetland in the eastern end of the proposed sewer line extension is primarily composed of a mixture of pasture grasses, and therefore, restoration by soil replacement and reseeding to prevent erosion should be appropriate for this area. Since the proposed impacts are temporary, and no trees or shrubs will be removed from the wetland, mitigation will not be required for the activities proposed within this area. The two trees to be removed along the western bank of the stream are not in wetland, however, the City of Tigard does require mitigation at a ratio of 1:1 (per diameter)for the trees. The trees to be removed are a 16-inch diameter breast- height (dbh)and a 32-inch dbh black cottonwood. Therefore, a total of 48-inches in diameter worth of trees will need to be planted. The City of Tigard is proposing to plant two thousand trees in 1999, a portion of which will satisfy the mitigation required for the removal of the two cottonwood trees during the construction of the proposed sanitary sewer line extension. The portion of trees to be planted as mitigation for the proposed sewer line extension will be installed at Cook Park in Tigard, Oregon. The plantings will include native species such as Douglas' hawthorn, willow, and red-osier dogwood. *Because this information is not necessary for a complete application, you may submit this sheet and other environmental information after submitting your application.

Alternatives considered: Except for stream corridor enhancement, most Type II and Ill uses are expected to develop outside of water resource and riparian setback areas. Therefore, Type II and Ill development applications must carefully examine upland alternatives for the proposed use, and explain the reasons why the proposed development cannot reasonably occur outside of the water resource or riparian setback area. There were no other alternatives considered for this project. Due to the topography, there are no alternate routes available to provide sanitary sewer service to the subject properties. B. Minimize site impacts: The proposed use shall be designed, located and constructed to minimize excavation, loss of native vegetation, erosion and adverse hydrological impacts on water resources. 1 . For Type II and III uses, the civil engineer with experience in water quality must certify that any adverse water quality impacts of the development proposal will be minimized consistent with best management practices. The project has been designed under the supervision of a Civil Engineer licensed in Oregon, and any adverse impacts will be minimized consistent with best management practices. 2. For all uses, the development shall be located as far from the water resource, and use as little of the water resource or riparian setback area as possible, recognizing the operational needs of the proposed development. Every attempt has been made to ensure minimal impact to the water resource. C. Construction materials and methods: Where development within the riparian area is unavoidable, construction materials or methods used within the riparian setback area shall minimize damage to water quality and native vegetation. The proposed construction will follow adopted City of Tigard, Unified Sewerage Agency, Oregon Division of State Lands and Corps of Engineers materials and methods for work in wetland areas. Proper erosion control methods will be employed during construction to minimize impacting the creek. Vegetation removal will only occur in the work area and reseeding/planting will occur immediately after construction to stabilize the site. D. Minimize flood damage: Above ground residential structures shall not be permitted within the WR overlay district, where such land is also within the 100-year flood plain. On site flood storage capacity shall not decrease as a result of development. The cumulative effects of any proposed development shall not reduce flood storage capacity or raise base flood elevations on or off site. No residential structures will be constructed as a result of this project. No decrease in flood storage capacity will occur, and base flood elevations will not rise as a result of this project. E. Avoid steep slopes: Within 50 feet of any water resource, excavation and vegetation removal shall be avoided on slopes of 25% or greater and in areas with high erosion potential (as shown on SCS maps), except where necessary to construct public facilities or to ensure slope stability. Because it is necessary to cross the existing creek channel to install a public facility, this standard does not apply. F. Minimize impacts on existing vegetation: The following standards shall apply when construction activity is proposed in areas where vegetation is to be preserved. 1 . Temporary measures used for initial erosion control shall not be left in place indefinitely; Upon completion of construction, all temporary erosion control devices shall be removed from the site and properly disposed of by the Contractor. 2. Work areas on the immediate site shall be carefully identified and marked to reduce potential damage to trees and vegetation; Prior to beginning construction, the pipe alignment will be staked for the pipe alignment and work area. 3. Trees shall not be used for anchors for stabilizing working equipment. During clearing operations, trees and vegetation shall not be permitted to fall or be placed outside the work area; No trees will be used for anchoring or stabilizing equipment. During clearing operations, trees and vegetation shall not be permitted to fall or be placed outside the work area. 4. In areas designated for selective cutting or clearing, care in falling or removing trees and brush shall be taken to avoid injuring trees and shrubs left in place. All care will be taken during tree and vegetation removal to avoid injuring adjacent trees and vegetation. 5. Stockpiling of soil, or soil mixed with vegetation shall not be permitted on a permanent basis. During construction there may be a temporary stockpile of material. There will be no permanent stockpiling of materials on site. G, Vegetation mitigation plan: If a Type II or III use is proposed within a water resource or riparian setback area, or mitigation is proposed as a method to reduce the riparian setback in accordance with Section 18.797.100, a mitigation plan shall be prepared and implemented. 1 . The applicant shall be responsible for re-vegetating areas temporarily disturbed by excavation on a 1:1 basis. Re-vegetation shall occur after installation of the proposed sanitary sewer line. The revegetation will consist of re-seeding the areas disturbed by construction and will include off site tree planting on a 1:1 basis. The Corps of Engineers permit, which is currently being reviewed, may have some additional planting requirements, which will be incorporated into the plan prior to construction. 2. Where approval is granted to reduce the riparian setback area, the applicant shall be responsible for mitigating for the reduced setback by replacing non- native vegetation within the remaining, protected riparian setback area on a 1.5:1 basis. That is, for each 100 square feet of riparian setback that is lost to development, at least 150 square feet of existing disturbed area within the riparian setback or wetland shall be replanted with native plant species. There will be no loss of riparian area to development for this project. 3. The re-vegetation plan shall provide for the replanting and maintenance of native plant species designed to achieve pre-disturbed conditions. The applicant shall be responsible for replacing any native species that do not survive the first two years after planting, and for ensuring the survival of any replacement plants for an additional two years after their replacement. The revegetation plan provides for the replanting and maintenance of native plant species designed to achieve pre-disturbed conditions. The applicant (City of Tigard) will be responsible for replacement of native plant species that do not survive the first two years and will ensure the survival of any replacement plants for an additional two years after their replacement. H. Water and sewer infiltration and discharge: Water and sanitary sewer facilities shall be designed, located and constructed to avoid infiltration of floodwaters into the system, and to avoid discharges from such facilities to streams and wetlands. The proposed sanitary sewer is designed using adopted City of Tigard, Unified Sewerage and American Public Works Association Design Standards. Refer to Exhibit "A". I. On-Site Systems: On-site septic systems and private wells shall be prohibited within the WR overlay district. There are no septic systems or private wells proposed for this project. J. Erosion control plan: If a Type II or III use is proposed within a water resource site or riparian setback area, the following erosion control standards shall apply within the WR overlay district: 1 . Specific methods of soil erosion and sediment control shall be used during construction to minimize visible and measurable erosion; Refer to Exhibit "A". 2. The land area to be grubbed, stripped, used for temporary placement of soil, or to otherwise expose soil shall be confined to the immediate construction site only. Clearing and grubbing is confined to the trench area. 3. Construction activity will take place during the dry season (June-October), whenever feasible and the duration of exposure of soils shall be kept to a minimum during construction. Construction will not begin until July, in conformance with the Corps of Engineers permit, and is anticipated to be completed in August. Trenches shall be backfilled immediately after placement of pipe, exposure of soils shall be kept to a minimum during construction. 4. Exposed soils shall be covered by mulch, sheeting, temporary seeding or other suitable material following grading or construction, until soils are stabilized. During the rainy season (November through May), soils shall not be exposed for more than 7 calendar days. All disturbed land areas which will remain unworked for 21 days or more during construction, shall be mulched and seeded. Exposed soils shall be hydroseeded immediately after construction and soil will be stabilized prior to the rainy season. 5. During construction, runoff from the site shall be controlled, and increased runoff and sediment resulting from soil disturbance shall be retained on site. Temporary diversions, sediment basins, barriers, check dams, or other methods shall be provided as necessary to hold sediment and runoff; Refer to Exhibit "A". 6. A stabilized pad of gravel shall be constructed at all entrances and exists to the construction site. The stabilized gravel pad shall be the only allowable entrance to the site. With the exception of the creek crossing, all construction will occur on an existing paved surface, this standard does not apply. 7. Topsoil removal for development shall be stockpiled and reused on site to the degree necessary to restore disturbed areas to their original or enhanced condition, or to assure sufficient stable topsoil for re-vegetation. Additional soil shall be provided if necessary to support re-vegetation; It is intended that all topsoil in the WR overlay area be reused to re-establish existing grades and support re-vegetation. 8. The removal of all sediments which are carried into the streets, water resources or on to adjacent property, are the responsibility of the applicant. The applicant shall be responsible for cleaning up and repairing streets, catch basins, water resource areas and adjacent properties, where such properties are affected by sediments or mud. In no case shall sediments be washed into storm drains, ditches or drainageways; The applicant is responsible for cleaning up and repairing streets. No sediments shall be washed into storm drains, ditches or drainageways. 9. Any other relevant provisions of the Erosion Prevention and Sediment Control Plans Technical Guidance Handbook (City of Portland Bureau of Environmental Services and Unified Sewerage Agency of Washington County, Revised February 1994), required by the Planning Director. The plans have been designed using these standards. Any additional requirements will be incorporated into the plans prior to construction. K. Plan implementation: A schedule of planned erosion control and re-vegetation measures shall be provided, which sets forth the progress of construction activities, and mitigating erosion control measures. An approved Erosion Control and re- vegetation plan shall be implemented and maintained as follows: 1 . Erosion control measures shall be installed prior to any stripping or excavation work. Erosion control measures shall be in place prior to beginning any construction activities. 2. The applicant shall implement the measures and construct facilities contained in the approved Erosion Control Plan in a timely manner. During construction, the applicant shall inspect erosion control measures daily, and maintain, adjust, repair or replace erosion control measures to ensure that they are functioning properly. Erosion control measures shall be in place prior to beginning any construction activities. Erosion control measures shall be inspected and maintained daily throughout construction. 3. Eroded sediment shall be removed immediately from pavement surfaces, off site areas, and from the surface water management system, including storm drainage inlets, ditches and culverts. Erosion control measures shall be inspected and maintained daily throughout construction. 4, Water containing sediment shall not be flushed into the surface water management system, wetlands or streams without first passing through an approved sediment filtering facility or device. Refer to Exhibit "A". 5. In addition, the applicant shall call for City inspection, prior to the foundation inspection for any building, or to certify that erosion control measures are installed in accordance with the erosion control plan. This project is a City of Tigard capital improvement project, and will be inspected daily by the City;s construction inspector to ensure erosion control measures are installed in accordance with the erosion control plan. • L. Type III conditional uses The procedural and substantive provisions of Chapter 18.330, Conditional Uses, in addition to Section 18.797.080 L1-2 below and 18.797.080A-K above, shall apply to determine whether a Type III use listed below may be approved. The applicant for conditional use approval shall; 1. Demonstrate that there will not be any net loss in the values of the resource area; and 2. Submit a detailed mitigation plan to show that any loss of riparian values will be fully compensated through the enhancement program. The proposed project is a Type ll use therefore, this standard does not apply.

[Refer to R&0 96-44/USA Regulations-Chapter 3,Design for SWM) WATER RESOURCES OVERLAY DISTRI W ER RESOURCES (WR) OVERLAY DISTRICT implements the policies of the Tigard Comprehensive Plan and is intended to resolve conflicts between development and conservation of significant wetlands, streams and riparian corridors identified in the City of Tigard Local Wetlands Inventory. Specifically, this chapter allows reasonable economic use of property while establishing clear and objective standards to: protect significant wetlands and streams; limit development in designated riparian corridors; maintain and enhance water quality; maximize flood storage capacity; preserve native plant cover; minimize streambank erosion; maintain and enhance fish and wildlife habitats; and conserve scenic, recreational and educational values of water resource areas. Safe Harbor: The WR OVERLAY DISTRICT ALSO MEETS THE REQUIREMENTS OF STATEWIDE PLANNING GOAL 5 (Natural Resources) and the "safe harbor" provisions of the Goal 5 administrative rule (OAR 660, Division 23). These provisions require that "significant" wetlands and riparian corridors be mapped and protected. The Tualatin River, which is also a "fish-bearing stream," has an average annual flow of more than 1000 cfs. Major Streams: Streams which are mapped as "FISH-BEARING STREAMS" by the Oregon Department of Forestry and have an average annual flow less than 1000 cubic feet per second (cfs). D Major streams in Tigard include FANNO CREEK, ASH CREEK (EXCEPT THE NORTH FORK AND OTHER TRIBUTARY CREEKS) AND BALL CREEK. Minor Streams: Streams which are NOT "FISH-BEARING STREAMS" according to Oregon Department of Forestry maps . Minor streams in Tigard include Summer Creek, Derry Dell Creek, Red Rock Creek, North Fork of Ash Creek and certain short tributaries of the Tualatin River. Riparian Setback Area: This AREA IS MEASURED HORIZONTALLY FROM AND PARALLEL TO MAJOR STREAM OR TUALATIN RIVER TOP-OF-BANKS, OR THE EDGE OF AN ASSOCIATED WETLAND, whichever is greater. The riparian setback is the same as the "riparian corridor boundary" in OAR 660-23- 090(1)(d). D The standard TUALATIN RIVER RIPARIAN SETBACK IS 75 FEET, unless modified in accordance with this chapter. D The MAJOR STREAMS RIPARIAN SETBACK IS 50 FEET, unless modified in accordance with this chapter. D ISOLATED WETLANDS AND MINOR STREAMS (including adjacent wetlands) have no riparian setback; however, a 25-foot "water quality buffer" is required under Unified Sewerage Agency (USA) standards adopted and administered by the City of Tigard.
