The proposed trunk line will run from SW McDonald Street, west of SW Hall Boulevard, northeasterly along a ravine to SW Hall Boulevard, then easterly to an area near Fanno Creek. USA has held two meetings with neighboring property owners to discuss the project and refine the project design. The City of Tigard requires an application for a Sensitive Lands Review because the project involves work within the floodplain and/or wetlands. USA is aiming to submit the land use application in April 1994 with a goal of starting project construction this Summer. Planning staff with the City of Tigard have indicated that a land use application must be submitted by the recorded property owner or contract purchaser. USA has not yet secured easements for the project and we are therefore requesting property owner signatures to allow USA to submit the land use application to the city of Tigard and act as authorized agent for the SenSitive Land Permit. tour signature only authorizes USA to submit the land use application and does not represent grant of any easement rights for project construction. We would appreciate it if you could sign the enclosed land Use application authorization and return it to me in the enclosed envelope by Aril 15, 1994. If you have any questions regarding this letter or the land use process, please contact me at 648-8621, or Dick Bewersdorf with the city of Tigard Planning Department (639-4171).

This letter is also intended to provide clarification concerning the submittal requirements for quasi-judicial public hearing items. Because the City has no immediate plan to develop a trail design or alignment for this portion of the Greenway Trail System, it is premature to have your landscape replacement plan address impacts to future bicycle or pedestrian trails. Section 18.32.040 of the CommUnity Development Code states that the following parties may initiate a quasi-judicial land use application: 1. Order of Council; 2. Resolution of a majority of the Cortmission; 3. The Director; 4, Application of a recorded owner of property or Contract. .purchasers. The Sensitive Lands Review •pplication cannot be considered complete for prodesSinq to public hearing before the Hearings Officer Until signed permission has been obtained from each owner of the affeeted properties (See attached Code excerpt) .

Hall Boulevard Tigard, OR 97223 Re Request for Planning Director Initiation of Land Use Application for McDonald Sewer Trunk Project Dear Dick The Unified Sewerage Agency has made an effort to obtain property owner consents for submittal of the land use application required for the McDonald Sewer Trunk Project in Tigard. I have enclosed a copy of the letter that USA mailed out to fifteen (15) affected property owners on April 8, 1994. We asked for return of the land use application authorization by April 15, 1994, As of April 15, USA had received authorizations from 8 property owners. Terry Chamberlin (project engineer for USA) expects that he may not receive authorizations from all of the property owners by the time we hope to submit the land use application to the City, Therefore, we request that the Planning Director initiate the application as allowed by the Code. USA will pay all required fees for the application, We have made a good faith effort to coordinate with affected property owners and obtain consents for submittal of the land use application. However, if we do not receive all of the consents, we do not want to rug the risk that the land use process will be flawed because it was not initiated by 100% of the affected property owners. Given that the decision on this application will be made by the Hearings Officer and not 4 the Planning Director, initiation of the application process by the Planning Director should not compromise the review or decision on the request, • • 6ia kE ALOIEbA .o. tiottfiAN't OREGON • FAX .60J/101,0$14 .

Backed Information: The general area in which the sewer line is proposed to be extended is within portions of the Edgewood Subdivision. The sewer line would also abut portions of the Filbert Park Subdivision. The alignment which was selected is within an area designated as a natural Greenway Area within the Park and Open Space Master Plan. The Greenway system is planned to contain bicycle and pedestrian trails to allow public recreational use. To date, dedication of these areas for Open Space has not taken place. The sewer trunk line has been proposed in order to discontinue use of the last remaining sewer pump station in Tigard. Site Information_ and Pro osal Descri t The project proposes construction of approximately 2,717 lineal feet of eight inch plastic sewer line. The project also proposes to install 17 sewer manholes. Upon com p letion, the Unified Sewerage Agency will restore ground elevations to their natural contours and reestablish and/or enhance naturally occurring plant species. The alignment of the sewer has been designed to avoid larger trees, ponds, sloping areas and to preserve large dead trees where possible due to their value as nesting sites. The entire length of this drainage area flows through private lots. The proposed sewer trunk line is within the rear and side yard of 14 developed single family residential properties., The proposed sewer line location is natural drainage area which contains deciduous and coniferous trees. A stream, ponds and emergent marsh areas exist over rntich of the proposed Sewer line alignment. The majority of the stream is channelized and does not contain marsh or wetlands area Portions of the stream towards SW McDonald Street have retained natural vegetation: Much of the natural vegetation in this area has been removed or replaced with ornamental species: Drainage ditches and open meadows predominate the sewer line alignment east of SW Hall Boulevard: The presence of various bird and small animal Species were confirmed in the vicinity through a wildlife survey of the area The Unified Sewerage Agency has also received required permits from the Army Corps of Engineers which are contingent upon completion of permits required by the HEARINGS OFFICER SLR 94.0001 MCDONALD SEWER TRUNK Page 2 State of Oregon. The Unified Sewerage Agency is also in the process of obtaining permits from the Division of State Lands. These agencies also review impacts to natural resources and may require measures to minimize environmental impacts. C. Vicinilanforrnation: The affected properties are developed with single family residences. This area is designated as a future Greenway Area within the City's Comprehensive Plan. The area is presently a drainage area located within a portion of the rear and side yards of properties developed primarily with single family residences. 1/1. APPLICABLE APPROVAL STANDARDS AND REQUEST EVALUATION A. COMMUNITY DEVELOPMENT CODE: Use Classification: Section 18.84.015(B) allows underground utilities as a permitted use within areas defined as a sensitive lands area subject to approval of a Sensitive Lands Permit by the City of Tigard and permit approval by the Division of State Lands, the Army Corps of Engineers and the Unified Sewerage Agency. splicable Am:oval Standards: Section 18.84.040(A)(C) sets forth the applicable approval standards for a sensitive land review involving areas within the 100-year flood plain and drainage ways. Section 18.84.040(A) provides the following criteria for development within the 100-year flood plain: 1. Land form alterations shall preserve or enhance the floodplain storage function and maintenance of the zero-foot rise floodway shall not result in any narrowing of the floodplain boundary. The proposed design of the project will restore the ground elevations within the 100-year flood plain to the current elevation contours upon completion. The applicant does not propose any net fill within the 100-year flood plan' 1, The drainage basin framework of necessity follows drainage features such as floodplains to allow for sewer gravity flow, 2. Land form alterations within the 100-year floodplain Shall be allowed only in areas designated ag commercial or industrial on the Comprehensive Plan Land Use Map, except that :alterations or developments associated with community recreation uses, utilities or public support facilities as defined ha Chapter 18,42 of thei Continuality Development Code shall be allowed in AiZINGS OPPICtit - SLR 94-0001 - MCDONALD SgWER TRUNIt. Page , , , • •,';•,-"` .4. areas designated residential subject to applicable zoning standards. Preconstruction ground contours will be reestablished upon completion of work. No buildings or impervious surfaces are proposed to be constructed. Where a land form alteration or development is permitted to occur within the floodplain it will not result in any increase in the water surface elevation of the 100 -year flood. The applicant proposes to restore contour elevations upon completion of the sewer line. Manholes within the 100 -year floodplain will be installed flush so that no increase in water surface elevation will occur within the 100-year flood plain. The land form alteration or development plan includes a pedestrian/bicycle pathway in accordance with the adopted pedestrian/bicycle pathway plan, unless the construction of said pathway is deemed by the Hearing's Officer as untimely. Although this area is designated within a portion of the City's Park and Open Space as a Greenway Area to be developed in the future with a bicycle and pedestrian pathway route the exact path alignment in this area has not been determined, This area is presently private property and not dedicated for Open Space use The Unified Sewerage Agency is negotiating a temporary 60 foot construction easement and a permanent 15 foot utility easement. Development of a trail in this area by the City of Tigard is not eminently contemplated. The proposed utility structure does not preclude the ability of the City to develop a trail through this area at a later date. By design the p ermanent utility tY easement will utilize low lying portions of this drainage area which may not be suitable for construction of a permanent bicycle and pedestrian pathway, The plans for the pedestrian/bicycle pathway indicate that no pathway will be below the elevation of the average annual flood: A bicycle or pedestrian pathway is not proposed to be constructed as a part of this project. The necessary U.S, Army Corps of Engineers and State of Oregon Land Board, Division of State Lands approvals shall be obtained, USA has Obtained a nationwide permit from the Corps of Engineers for this project: The applicant has also applied for project permits through the Division of State Lands. where land forth alterations amldior development are allowed within and adjacent to the 100 -year floodplaaiai, the City shall require the dedication lit A:RINGS OFFICER SLR .0 4.0001 Mc DONALD S WE'R TRUNK Page 4.

This utility project involves land form alterations but not new development. The Unified Sewerage Agency is not the owner in fee properties. applicant have the of the affected xo ernes. For this reason the a l�caunt does not ability to dedicate areas within and adjacent to the 100 -year floodplain to the City. Should the City pursue design and construction of a pathway at a later date, right -of -way issues will, be addressed. Section 18.84.040(C) provides the following criteria for issuance of a sensitive lands permit for areas within a drainageway based upon compliance with the following criteria: 1. 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 applicant conducted Wetlands and Wildlife Habitat Evaluations. Both studies concluded that with appropriate erosion control and landscape replacement measures that no long term environmental impacts would result due to this project. Ground contour levels will be restored to their existing elevation upon completion of work. The pipe alignment is designed to avoid large trees and wildlife habitat areas to the extent feasible. A landscape plan has been provided which replaces existing vegetation which presently includes various ornamental species with native plant species. 2. The proposed p.. result in be r® Deed eland form alteration or development will not resu erosion; stream sedimentation, ground instability, or other adverse on -site and off -site effects or hazards to life or property. Construction work would take lace during s .. p during unnnier months to minimize erosion, stream sedimentation and ground instability, Construction of temporary clay dams along the pipeline will be constructed to ensure the project will not drain the existing wetland. The Unfified Sewerage Agency will monitor erosion control methods with the contractor. No fill of soil is proposed in conjunction with this project. The water flow capacity of the dra' . P � unag e�`a y is not decreased, The applicant states that the installation of an underground sewer line will not decrease the waterflow capacity of this drainageway. MARINES OFFICER:.

All other applicable City requirements must be satisfied, including sensitive land permits for areas meeting non - wetland sensitive land criteria. All requisite permitting is underway or completed with both the Division of State Lands and the U.S. Army Corps of Engineers. Other City review requirements for potential environmental impacts to areas of this project within the 100 -year floodplain and drainageways are addressed within this report. Tree Removal Section 18.150 contains standards for obtaining a required permit for removal of trees on site which have a trunk six inches or more in diameter measured four feet above the ground. The site plan indicates that several mature trees are proposed to be removed. Because this project is within an area developed with single family homes of less than three acres each, the Development Code exempt these properties from tree removal permit requirements. The property located at 13560 SW Hall Boulevard exceeds three acres. Condition of Approval #2 requires that prior to removal of trees on this parcel that the applicant will obtain tree removal permits. The proposed design � of the project, sensitive construction techniques, landscape replacement, and enhancement plan will preserve trees where possible. The project design would replace trees with native species which will eehance or reestablish native habitat in the area. COMPREHENSIVE PLAN POLICIES: l.

The Agency conducted a study of existing pump station to determine the feasibility of removing the pump station by construction of a gravity sewer line or upgrading the pump station to meet the current federal standards. The study recommendation was to remove the McDonald Pump Station by constructing a gravity sewer line to the ranno Creek Sewer Interceptor. PROJECT DESCRIPTION The project consists of constructing 2,740 feet of 8-inch sanitary sewer line. The project is located mostly in an unnamed drainage just north of the intersection of SW McDonald Street and SW Hall Blvd. The project starts on the east side of Fanno Creek, crosses the creek and follows the property line to SW Hall Blvd., then crosses SW Hall Blvd. and travels up the drainage swell in a southwesterly direction to SW McDonald Street. Currently, there is a dry sewer line existing in SW McDonald Street that dead ends where this Project ends. The existing sewer line was constructed by the City of Tigard when SW McDonald Street was improved. PROJECT IMPACTS AND ALTERNATIVES The project impacts are described in the attached Wetland Evaluation Report Prepared by OTAK, Inc. In order to provide sewer service to this area of the City of Tigard, the proposed project is needed and there are no other alternatives. DESCRIBE.

The proposed impact areas were assessed in a wetland determination and evaluation. During the field work for this project, OTAK'o wetland biologist characterized and analyzed the wetland functional value along the corridor proposed for placement of the sewerline trunk. The wetland boundary and the four different types of wetlands along the length of the stream can be shown adequately and since the project will not impact more than a narrow corridor within the drainage basin, the exact wetland boundary related to the width is not required for the mitigation plan. The placement of the sanitary sewerline within the stream corridor will impose minimal impacts to the wetland and any material removal will be replaced directly back in the wetland upon the completion of the construction. SITE DESCRIPTION The site is located in Tigard, Oregon in the vicinity of the intersection of S.W, McDonald Street and Hall Boulevard, (Figure. 1) The proposed trunk begins at McDonald Street and runs east along a tributary of Fanno Creek flowing east to Hall Boulevard. The proposed trunk continues east perpendicular to Hall Boulevard along a property easement to Fanno Creek, It crosses the creek and terminates approximately one hundred feet east were it ties into an existing sanitary sewer trunk. METHOD Site information was collected by OTAK's wetland biologist, Jack D Dalton on September 4, 1993. Areas on either side of the tributary to Fanno Creek and Fanno Creek were surveyed to ensure the review of all of the wetland areas in the vicinity of the proposed sewer line trunk. Subsequent to the background research, Mr. Dalton completed the proposed determination, evaluation, and mapping of the wetland area. The following steps were included: • Project plans were reviewed; o Appropriate topographic, geological, and soil maps were consulted; o Recent aerial photographs were reviewed, • Oriusite vegetation, soils, and hydrology were characterized; and • Proposed determination and evaluation was made, The determination 'Ind evaluation report have been prepared in accordance with the Routine Method and Atypical Situation Method found in the 1987 Corp orgrigineett Wetland Delineatian Manual, The Routhie method was used rather than the Intermediate Method which uses transect lines i because the wetlands are primarily 4118/wetitihd,tep 0993,22 ,442, OTAX associated with a stream channeliaed, the boundaries of which can be located relatively easily by analyzing the topography of the area. Upon determination of the wetland indicators on site, an evaluation and delineation of the wetland boundaries has been re ared. As discussed before, the impacts from the p p proposed construction within the wetland area nn site are confined only to the stream bed and along an upland section east of Hall boulevard. For this reason, a wetland boundary was not surveyed by locating flagging in the field. Instead the wetland ry upon preformed by which determined the boundary is based u on the field work reformed b I�dr.

Essentially, this means that the ground must be saturated between 8 to 12 consecutive days during this time for the criterion to be satisfied. The hydrological regime of this site includes a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard through a series of channelized and undisturbed drainages and diked ponds. The tributary flows under Hall and continues east through two more diked ponds and feeds into Fanno Creek. The entire length t stream has been lea h of the stream flows through private lots= In some areas the s ` i stream has been g allowed to expand and the backside of lawns and under small bridges channelized into narrow along such as in the section between McDonald and Hall. The impoundments found periodically along the stream provide different habitat, but these are limited in sizes Only in a few short sections has the stream remained in its natural condition and the diversity of the vegetation in these areas reflect this observation. One of these sections is located west of Hall Boulevard and the other is along Fanno Creek itself on the eastern edge of the project site. The U.S. Fish and Wildlife NWI characterizes four wetland types in the drainage system associated with this project` The stream west of Hall Boulevard is listed as palust,.rine, forested, broad -leaf deciduous, saturated \semipermanent\seasonal for most of the length except for the emergent areas listed as palustrine, emergent marsh, persistent, as ed ip p.

Obligate wetland plants are those found in wetlands greater than 99% of the time. The vegetative communities along the Fanno Creek tributary are comprised of a mixed with some areas possessing an emergent or forest of deciduous and coniferous trees w g fir, open water component: big-leaf Within the mixed forest are included understory � �1 o �iirubs small maple, willow species, red alder and Western red cedar. The ry trees, and forbs varied depending upon the condition of the hydrology and the extent of the human disturbances. Vegetation found at the individual data points is recorded on the data sheets (Appendix A) and a species list for the project area is in Table 2. In (Figure vegetation exists along a nar;�cw stream n section 1 lF� re 2) thwide tfrom the outflow of the culvert under McDonald Street and then becomes an emergent marsh area extending to the first fenceline crossing the s tream: In this area, Himalayan imala y an blackb er ry and horsetail ow the edges es of the draina a basin int o the wetland area.

The diked pond area° tend to support a good diversity of plant species as well, where the emergent community is contained within the mixed forest community, Emergent species such as slough sedge, bulrush, and spreading rush are found in the more saturated soils and wood violet, waterleaf, curly dock, morning glory, wood fern, himalayan blackberry, English ivy, and willow form the vegetative community lining the stream and ponds. The tree layer contains the same deciduous and coniferous species found previously. Section 3 (Figure 4) of the project area includes the drainages adjacent to Hall Boulevard and the open meadow area on the property directly east of Hall. The vegetation in the drainage ditches and surrounding the culverted crossing is minimal. A small amount of reed canarygrass and horsetail has established itself in the bottom of the drainage and velvet grass, cultivated grasses (fescue and rye species), Himalayan blackberry, orchard grass extend from the drainages dip into the open meadow and lawn areas on the adjacent properties. The Fenno Creek tributary flows through the open field on the east side of Hall Boulevard and drains into a diked pond. This length of the stream is off of the project site, but the stream continues out of the diked pond and flows p north across the p easement highly where proposed y li ne trunk k route passes. The stream at this location is disturbed by human activities and the most p revalent vegetation is Himalayan blackberry, Along the north side of the easement, a row of trees exists containing hawthorne, Oregon ash, willow mixed with a thick growth of blackberry, There is a zone of saturation extending from the easement south where it forms a small emergent area between the portion of the tributary the trunk crosses and Fanno Creek, This marsh area is outside of the proposed trunk line, The proposed trunk route follows the row of trees until it reaches the west bank of Fenno Creek which is the last section, section 4, assessed in this report (Figure 5), Fan i Farina Creek is dominated by red -oiser dogwood, willow, Oregon ash with a mix of red alder, hawthorne, himalayan blackberry, Pacific ninebark, and scotchbroonn lining the banks, The structure and diversity is extensive and provides significant habitat. The open meadow area south of the property easement contains bent grass, velvet grass, thistle, common trn.s Yt Phalars, and isolated clumps of Pacific willow. 47 i8 /wetU5nd,i'ep 6998,2 1 w MODONALD SANITARY SE' EBLINE TRUNK a WETLAND DELINEATION REPORT OTAK EVALUATION As a functioning biological system, wetlands can serve an ecosystem in a number of capacities. Wetlands function as habitat for wildlife, as a storage place for floodwaters, or they can function to purify the water that moves through them. The level at which a wetland functions is termed its value or functional value. It is this value that the regulations intend to protect in the `no net loss' rules. The wetland areas on this site were evaluated based on the WET II evaluation method. This teethed identifies 11 wetland functions (see Table 1) and provides the parameters to determine if these functions for a particular wetland area have a high, medium, or low value. Section 1 and 2: These sections are moderate to moderate -high. They are less disturbed in general than the assessed wetlands east of Hall Boulevard. Food chain support and wildlife habitat , remain presence of are both moderate to high. These functions ret�air� high due bthe od structure essentially continuous habitat along the entire stream course providing ... both vertically and horizontally. positioning the emergent area directly adjacent e nt to the mixed forest community p rovide higher diversity as a food source and greater habitat availabilit Y n Shoreline protection remains moderate and floodwater storage is moderate. The presence as directly along the bank of the stream in these sections lower the ability of the wetland to absorb greater stream flow and don't s t Y contribute as much to the protection of the banks from erosion The presence of the pond , however, adds value to the floodwater storage function. The groundwater recharge and discharge a ual out in this type of drainage basin. The semi - permanent condition of the stream increases the ability of the discharge function and the slow permeability of the soils here limit the amount of recharge function. The periodic ponds alg drainage the draina e tend to increase the extent of the recharge and serves to limit the � discharge: Functions contributing to water quality value in the drainage range from moderate to moderate -high due to the high density of the forb and shrub vegetative layers. Again, the presence of lawn directly iy saturation zone of the wetland tends in the saturati to lower the water quality from levels found in emergent areas as well as contributes to the amount of nutrients and sediment which result from fertilization and ground disturbances on the lots along the stream= Section 3 and 4 These sections e noderate and slightly lower quality on the average compared a i to the other two sections, are are smaller er in 1 ns, Als o the wetlands within the proposed trunkl�ne a acreage e and this tends to lower the value, support and wildlife habitat are g Food chain sup moderate-high function due the continuous habitat in of layer o to -hi h to n tree and shrub la g forested ,.. d corridor of Fenno contribute and the foreste between the open meadow +al� along s�t� °oritrtbute to both functions, Functions the strewn course diversity describing and ha se and the baulks are difficti ►t to assess within the easement g because the proposed truhkline crosses the Fahno Creek tributary and Fenno Creek and 4j7 (��18�y/wetland,rep 0993, y 2 10 �yi:i1, yy OTAK these functions are valuable only when an entire length of stream bank or stream is assessed. There is a presence of vegetative structure contributing to the integrity of the bank. (See data sheet 13) The groundwater discharge is moderate -high due to the intermittently a osed/pery nent condition of Fanno Creek and the lack of any significant areas where ondin can develop and contribute to the groundwater recharge. .... The remaining functions are low to moderate either due to the absence of significant amounts of emergent vegetation and the high degree of bank erosion on this portion of Fanno Creek. In these new, the crossing must not impact the present condition of the stream banks, which specifically can be measured by the vegetation present, because the impacts would likely effect areas downstream in Fanno Creek.The minimal impact acreage results in lower mitigation requirement and if the construction is conducted appropriately the impacts to the drainage system will also be minimal, 41 3 /wet1and,rep 0993,12 r • TABLE 1.

During the field work for this project, OTAK's wetland biologist characterized and analyzed the wetland functional value along the corridor proposed for placement of the sewerline trunk. The wetland boundary and the four different types of wetlands along the length of the stream can be shown adequately and since the project will not impact more than a . narrow corridor within the drainage basin the exact wetland boundary related to the width is not required for the mitigation plan. The p lacement of the sanitary sewerline within the stream corridor will impose minimal impacts to the wetland and any material removal will be replaced directly back in the wetland upon the completion of the construction. SITE :3ESCRIPTION The site is located in Tigard, Oregon in the 'Vicinity of the intersection of S.W. McDonald Street and Hall Boulevard: (Figure: 1) The proposed trunk begins at McDonald Street and runs east along a tributary of Fanno Creek flowing east to Hall B proposed trunk Boulevard. The p k continues east perpendicular to Hall Boulevard along a property easement to Fanno Creek: It crosses the creek and terminates approximately �' one hundred feet east were it ties into an existing sanitary sewer trunk. METHOD Site collected by OTAI{'s wetland biologist, Jack D. Dalton on Site information wa$c September 4, 1993. Areas on either side of the tributary to Fanno Creek and Faith() Creek were sury ' r view of all of the wetland areas in the vicinity of eyed to ensure the the proposed � fine Subsequent o the background research, Mr, Dalton sewer line trunk. Subse uent t Completed proposed determination, evaluation, and mapping of the wetland area. The following the ste s were included: P • • • Project plans were rev ie ed; Appropriate to Fd �a hlc, eo lo e g ical, and soil oil maps were consulte d, Recent aerial photographs werreviewed; vegetation, soils, and hydrology were chara. cerized; and Proposed determination and evaluation was Made: The l �i ., : n.. and evaluation report have been prepared in a ccordance with the Routine Method and Atypical Situation Method found in the 19$7 Corps o f Engineers Del�ation Manual. The Routine method was used rather than the Intermediate Method which uses transect lines, because the wetlands are primarily Inter d7 i8 /*& itaidiep 099322 MCDONALD SANITARY SEWERLINE TRUNK WETLAND DELINEATION REPORT OTAK morommowommorwrar. associated with a stream channelized, the boundaries of which can be located relatively easily by analyzing the topography of the area. Upon determination of the wetland indicators on site, an evaluation and delineation of the wetland boundaries has been prepared. As discussed before, the impacts from the proposed construction within the wetland area on site are confined only to the stream bed and along an upland section east of Hall boulevard. For this reason, a wetland boundary was not surveyed by locating flagging in the field. Instead the wetland boundary is based upon the field work preformed by Mr. Dalton which determined the approximate boundary and shown on the 1"=50' map prepared by Westlake Consultants, Inc. (See figures 2-5.) The areas impacted by the proposed activities can be located easily from the detailed topographic information. The stream is divided into four sections to aid in reference to the narrative. • The functional value analysis has been preformed using the Wetland Evaluation Technique 2.0 (WET II) developed by the Federal Highways and Army Corps of Engineers. a •••0093,4 • InLIL''f'1 LAI MI waft itqks PI PI FIGURE 1. lnceep ebted i*mt sw n i., Lod osh aoR v7o3s (500 .9e1e f t° IgM 1Wadi, loo; ideid end WA ems, l • MCDONALD SANITARY T RUNK - ETgA.ND DELINEATION REPORT OTAK WETLAND HYDROLOGY In order for the hydrologic criterion for a jurisdictional wetland determination to be satisfied there must be enough water in a given area to saturate the soils within 12 inches of the surface for a duration of no less than 5% of the growing season. The growing season of the prevalent vegetation is loosely defined as the time in which a majority of the vegetation has begun to grow, generally between the months of March through or hrough S Se p tember in the Pacific Northwest. Essentially, this means that the ground must be saturated between 8 to 12 consecutive days during this time for the criterion to be satisfied. The hydrological regi me of this site includes a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard through a series of channelized and undisturbed drainages and diked ponds.

This soil is classified as being hydric by the SCS. This soil is generally located in concave surfaces in broad valley basins. It is a poorly drained soil formed in mixed silty alluvium and the permeability is slow. Runoff is slow to ponded and the hazard of erosion is slight. On Dither side of the stream basin the soil is identified as Quatama silt loam This soil series is not documented as being hydric, however, inclusions of the hydric Huberly soil series are possible in this region. This soil is described as being moderately well drained forming in mixed, loamy alluvium on old terraces. The permeability is moderately slow and the hazard of erosion is slight. The soil forms on gently sloping terraces of 3 to 7 percent slope.

Wetlands function as habitat for wildlife, as a storage place for floodwaters, or they can function to purify the water that moves through them. The level at which a wetland functions is termed its value or functional value. It is this value that the regulations intend to protect in the `no net loss' rules. d The wetland areas on this site were evaluated based on the WET i1 evaluation method. This method identifies II wetland functions (see Table Ii and provides the parameters to determine if these functions for a particular wetland area have a high, medium, or low value. Section 1 and 2: These sections are moderate to moderate -high. They are less disturbed general than the assessed wetlands east of Hall Boulevard: Food chain support and wildlife habitat are both moderate to high, These functions remain) high due to the presence ood structure i g. e:: providing arn g essentially continuous habitat along the .,stirs stream hec emergent vid ea directly adjacent both vertically and horizontally.

There is a presence of vegetative structure contributing to the integrity of the bank. (See data sheet 13) The groundwater discharge as moderate-high due to the intermittently exposed/permanent condition of Fanno Creek and the lack of any significant areas where ponding can develop and contribute to the groundwater recharge. The remaining functions are low to moderate either due to the absence of significant amounts of emergent vegetation and the high degree of bank erosion on this portion of Fanno Creek. In these areas, the crossing must not impact the present condition of the stream banks, which specifically can be measured by the vegetation present, because the impacts would likely effect areas downstream in Fanno Creek,The minimal impact acreage results in lower mitigation requirement and if the construction is conducted appropriately the g 9 impacts to the drainage system will also be minimal. 4'' iii /wetlar d,rep 0000g 11 C ;`. */1. •■?* MC/DONALD SANITARY SEWERLINE TRUNK WETLAND DELINEATION REPORT OTAK TABLE 1.

The riparian corridor is associated with a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard. The tributary includes natural riparian areas as well as channellzed drainage and diked pond areas. The stream flows under Hall Boulevard and continues east to Fanno Creek. The site was evaluated for current wildlife habitat conditions and for potential impacts associated with the proposed project. As planned, the project is expected to have minor p J. ,p ; � P J ; ,p . effects upon wildlife populations in the riparian area, Opportunities for minimization of impacts exist and have been identified in this report; Similarly, recommendations regarding the wetland mitigation landscaping plans can also be found in Appendix B. This report was organized to complement the Wetland Delineation Report prepared for this i . site b y OTAK in September of 1993 The stream ha s been divided into four sections for easy reference. The stream sections and data points n sed in the Y . p used are identical following guidelines delineation report. This wildlife habitat assessment was performed g gu found in the Habitat Evaluation Procedure developed by the Portland Audobon Society, the Oregon Department of ' j Wildlife, U S Fish and Wildlife Service, U.S. EPA, and the f Fish and ' Wetlands Conservancy: Additional protocol development support was obtained from the U.S. EPA's Stream Walk. program.

In the original report, wetland functional values were evaluated for the proposed project impact areas. USA has since requested OTAK to provide further information regarding wildlife and wildlife habitat values associated with the project area. This additional evaluation will address short and long term impacts on existing wildlife and provide additional information regarding the wetland mitigation plan. SITE DESCRIPTION The site is located in Tigard, Oregon, in the vicinity of the intersection of S.W. McDonald Street and Hall Boulevard (Figure 'gu 1), The proposed trunk begins at McDonald Street and runs east along a small tributary of Fanno Creek to Hall Boulevard, The trunk continues east, perpendicular to Hall Boulevard, along a property easement to Fanno Creek, It crosses the creek and terminates in approximately one hundred feet, where it ties into an existing sanitary sewer trunk, METHOD Site information was collected during two site visits. The first Was performed by Jack Dalton and John Lee (OTAK) for the purpose urpose of evaluating remaining wetland mitigation issues g e, This occurred between the hours of 1:00 pm and 4,00 m on and documenting wildlife us p sues March 22, 1994, The second site visit occurred between 9,30 am and 12.00 pm on. March 24, 1994 and was performed by Michelle Wilson (OTAK) to assess potential wildlife impacts associated with the planned project, In e f i rails assessment, the following steps were included. • J plans reviewed; • The wetland delineation report was reviewed; Recent topographic maps were consulted; • Wildlife habitat, cover; and food Values were characterized, A list of wildlife species present on the site or thought to be present on the site wag compiled, An assessment of potential short and long term impacts to wildlife was made, based on the anticipated effects of the proposed project, The wildlife habitat assessment was performed following guidelines found in the Habitat Evaluation Procedure develo p ed b y ihe Portland Audobon Society the Oregon Department of Fish and Wildlife, U,S, Fish _:. a nd Wildlife Service) U,S, EPA ) and the Wetlands Conservancy, Additional protocol development support was obtained from the U,S', EPA ''s Stream Walk program P3��7i8��BREP' 49446 ~r' ti " v � " '' ,.r'4. t . .' - S SPARE S SSI IN Mall S4 IR:11 ' S'Silt.

Where possible, the general habitat types have been discussed in relationship to the wetland value data previously collected (Data Forms, Appendix A). Section 1 This section, which contains the highest quality wildlife habitat of the project area, extends east from McDonald Street to the private sports court area located downstream (Figure 2). The western portion of this section contains a narrow stream which emerges from a culvert passing under McDonald Street. The stream opens into an emergent wetland, filled with reed canarygrass and Himalayan blackberry, and is surrounded by a mixed forest with a diverse understory, The proximity of this forest to the emergent wetland enhances the value of this site, as does the presence of numerous standing dead trees (snags). The habitat diversity in this area is demonstrated by the concentration of numerous bird species. The dense forest canopy and the understory shrub layer provide good structure and diversity, resulting in excellent habitat values, The forb layer, mostly intact at the time of this Visit, contributes to the high habitat and forage values. At the eastern edge of the meadows the stream becomes confined to its channel again as it p asses through g a light g forest into a residential area The homes located on the north side of the creek have impacted habitat value. The stream has been channelized in this area and several small dikes have created ponds adjacent to residential backyards, As the creek moves east toward the sports courts dominant hydrophytic drophytic vegetation (skunk k ca b bage) is replaced by lawn grasses. B are soil and a barking dog also detract from ha bitat value in this deciduous area. However, the southern side of the creek remains a mixed d c ous forest, whose presence helps to preserve some of the habitat values in this area, This forest provides i g high quality ity i +., ... the moderately high quality area linkage e between the hi h uali habitat upstream and downstream. The understory and forb layers in this forest are minimal.

This forest contains mixed deciduous and coniferous species and the shrub layer ranges from intact to absent. Several large western red cedars exist in this area Wildlife cover, nesting, and escape values are moderate to high here, and the presence of food and a consistent water supply further add to the value of this portion of the riparian corridor. Upon emerging from this forested area, the stream flows into a large pond with rip - rapped banks. The pond is surrounded by mowed lawn grasses and has the feel and appearance of a back -yard water feature. The proximity of this feature to residences makes it unlikely that it supports much wildlife, with the exception of ducks. The pond has a silty substrate dominated by decaying organic material and the water quality is moderate to poor. Vegetative diversity is low, food values are low to moderate, and the pond is exposed and lacks significant cover. Section 3 The pond terminates in a culvert, which carries stream flow under a fence and into a rip- rapped channel '� back yard (Figure 4)i The habitat values in this area are very low, as the dominant vegetation consists almost exclusivel. of mowed lawn grasses and the low, g exclusively creek is fenced and culverted as it passes through multiple private property lots, rd provides an effective barrier to all ., Hall Boulevard, traveling along the creek, Hall Bouleva p barrier wild). species elan a on into p es: After passing under a l it not in th culvert, the with the exception of bird species. p g levard via a cu creek flows into an open field, where it is again ponded.

WILDLIFE Numerous species of birds were observed using the project area for habitat, including; robins, jays, wrens, chickadees, finches, sparrows, ducks, and a red tail hawk (Table 1). Evidence also exists to indicate that woodpeckers frequent the project area Bird activity is particularly heavy in the western portion of the site. Species not visually confirmed on site, but whose presence are suspected due to indicators include: frogs, newts, snakes, field mice, raccoons, possums and other small mammals. The indicators include ideal habitat conditions, burrows, nests, runs and evidence of serrated and chewed vegetation, In addition, fish species known to be present in Fanno Creek include: cutthroat trout, crappie, red side shiners, bluegill, carp, dace, sculpin, three-spine sticklebacks (Tualatin Fish and Water Quality Report, DEQ 1987). SHORT TERM IMPACTS/MITIGATION OPPORTUNK AES Removal of 'Vegetation Removal and damage of vegetation during construction is an unavoidable impact associated with this project, However, many of the points located along the proposed aligninent are dominated by invasive vegetative species, Removal of these species is expected to have a low to moderate impact upon habitat values. Thee impact can be mitigated for by replacement vegetation that is higher in wildlife forage) cover) and habitat value, An effort to avoid removal of snags is encouraged. Water Quality Short term impacts to water quality are possible as a result of sewer line installation in the riparian corridor, To minimize potential sediment loading of th0 ponds and stream, USA is encouraged to complete the conStruction during the dry weather season. In addition, filter fabric or some other sediment barrier Should be placed between construction work and the water body, In area Where vvork may occur directly in the stream channel, downstream silt barriers should be in place to prevent excessive downstream silt and debris migration, Guidance regarding these iSgues can be obtained from ]SL and ODF&W. An additional effort should be made to revegetate diattrbed soils as quickly as poSsible following constrtiction, Exposed soils create the potential for erosion and sediment loading during rain storms and a hOtild be stabilized immediately after construction, PM/ ifi\HAB.REP 494d3 9 COMMON NAME Aix aponsa Anas platyrhynchos Aphelocoma coerulescens Buteo jamaicensia Carpodacus mexicanus Junco hyemalis Pans atricapillus Passerella iliaca Pipilo erythrophthalmus Regulus calendula Troglodytes troglodytes Turdus migratorius Wood Duck Fox Sparrow Rufous- sided Towhee Ruby- crowned Ringlet Winter Wren American Robin Pt\PRoJEc 718 \WILDrt8 MCDONALD STREET SANITARY SEWERLINE TRUNK - HABITAT ASSESSMENT OTAK Direct WffilirrIrancts No significant impacts to wildlife are anticipated. The tributary stream does not provide suitable fish habitat and direct impacts to fish are unlikely. Placement of sediment control devices should protect Fanno Creek fish apecies, but input on this issue will be required from the Division of State Lands and the Oregon Department of Fish and Wildlife prior to project initiation. Impacts to small mammals and bird species are expected to be minimal. LONG TERM IMPACTS Long term impacts associated with the proposed project are expected to be minimal to non- existent in their effects upon wildlife, Impacts resulting from installation of the sewer line can be effectively mitigated for and minimized through cautious planning. The impacts associated with long term maintenance and sewer line repair are not expected to pose a threat to wildlife or habitat values, provided that heavy equipment is kept out of the riparian area. However, long term impacts would be anticipated if an access road or trail system were developed in the riparian corridor, Habitat values along this site are somewhat fragmented and placement of such a structure, without habitat mitigation, could further add to this fragmentation. Similarly, the increase in human activity levels associated with the improved access and physical habitat disturbances would detract from the current wildlife habitat value, CONCLUSION The proposed McDonald Trunk sewer line is expected to have minimal impacts upon wildlife and wildlife habitat in the project area Cummulative impacts anticipated off site and downstream of the crossing point on Fanno Creek are expected to be negligible, PA47181/TABAEP 494,16 4 , , MCDONALD STREET SANITARY SEWERLINE TRUNK OTAK HABITAT ASSESSMENT ADDITIONAL WETLAND MITIGATION RECOMMENDATIONS Upon reviewing the landscaping plans for the McDonald trunk sewer line, OTAK makes the following observations and recommendations: ® Replace "Laurel" with "Scouler Willow"; Replace "Holly" with "Service Berry "; Replace "Maple" with "Red Alder'; Replace "Ash" with "Red Alder "; Replace "Nootka Ross" with " Nootka Rose "; Specify "Red -Osier Dogwood ", rather than just "Dogwood'; Scouler willows should be planted in pods; planted pods three. A triangular pattern is recommended, � Dogwoods should be lamed to enhance seed dispersal; rather than a linear pattern, Spirea clusters of 30 plants are recommended (4 -5 pods of 6 plants in each group, 3 feet on center); al Woody plants (trees and shrubs) should be planted where the soil is moist from creek saturation, If outside of this moist area, artificial irrigation will be necessary to ensure long -term plant survival, ` details have in Section 1 and Section 2 planting ve been made , A (See: trRevised Landscaping ng Plans), Ground covers of meadow fescue, meadow foxtail and clumping rye grass arer recommended for soil stabilization and fort) la er development.

INTRODUCTION A. Description of Project The Unified Sewerage Agency (USA) is requesting City of Tigard approval of a Sensitive Lands Permit to remove the McDonald sewer pump station and install a gravity sewer line extending from S.W. McDonald Street on the southwest to an existing USA transmission main on the northeast side of Fanno Creek, Construction of this project will allow the city to activate the dry line installed in McDonald Street in 1992 and will convey sewage by gravity flow to the Durham Wastewater Treatment Plant. The project involves construction of approximately 2,717 lineal feet of 8 inch plastic sewer line, Elevations range from approximately 178 feet on the west where the new line will tie in with the existing 8" sewer in McDonald Street to approximately 120 feet on the east side of Fanno Creek where the gravity line will tie in with the existing 60" USA transmission main to the Durham Treatment Plant. Existing contours will be restored following construction of the sewer line. The project will also involve installation of 17 manholes as illustrated on the plan & profile drawings. As part of the update of the USA Facilities Plan, the agency evaluated all pump stations for compliance with EPA standards (dual power grid, etc.) The existing McDonald pump station is old and USA concluded that it would cost less to remove the pump station and construct a new gravity line relative to the cost associated with upgrading and maintaining the pump station, including power requirements, When this pump station is removed, there will be no sewer pump stations remaining in Tigard. The McDonald Trunk Project is included in the Unified Sewerage Agency 5-Year Capital Improvement Plan, The proposed alignment for the new 8 inch gravity sewer line is illustrated on the following exhibit, Detailed plan & profile drawings are included in the Appendix. Following construction, the McDonald Trunk will become part of the City of Tigard sewer collection system and vvill be maintained by the City, The City will have jurisdiction over any hook-ups to the new sewer line. Several dwellings in the project vicinity are served by septic systems, The City of Tigard provided a letter to USA on January 11, 1994 which noted that the following permits were required for the McDonald Sewer Trunk Project: Street Opening permit The Engineering Department issues street opening permits to review connections to the City sewer line, Three sets of plans are required. No fees or performance assurance is required, USA has obtained the Street Opening Permit from the Tigard t ngineering Department (Pennit #641), 1 [Page Too Large for OCR Processing] Sensitive Lands. _ Permit Work within the floodplain or wetlands requires a sensitive lands review from the Planning Division. The process involves public notice and a hearing and decision by the Tigard Hearings Officer: Based on the letter from the City of Tigard, no other local land use permits are required for the project. Representatives of USA met on two occasions with Tigard planning staff to discuss submittal requirements for the Sensitive Lands Permit.

At the second meeting, USA shared the proposed design and OTTA K wetland report. Additionally, input was requested on the proposed landscape restoration plan. Sunnnary notes of the two neighborhood meetings are included in the Appendix. Elements of the J ro'ect design have been modified in response to input from neighbors. p g In particular, USA has attempted to align the sewer line to minimize the need to cut large trees and avoid impacts on existing ponds. In April of 1994, USA mailed out letters to affected property owners requesting authorization to submit this land use application to the City of Tigard. To date, .T SA has � received written authorization from 10 of the affected property owners. A copy o ; the letter from USA requesting authorizations for the land use application is also included in the Appendix. In February of 1994, Mark Jockers of USA spoke with Liz Newton of the City of Tigard regarding the need to take this project to the . Team. Because South Citizen Involvement Tea affected of the small area involved, Ms. Newton recommended working directly with the a neighborhood as USA has done. II. GENERAL INFORMATION A. Vicinity Conditions 1. Location & Land Characteristics The McDonald Trunk project covers a distance of about one -half mile, extending from S.V. McDonald Street on the west to about 100 feet east of Fanno Creek. Elevations range from 178 feet Mean Sea Level (MSL) on the west end of the project to a little above 120 feet MSL on the east: The 100 -year flood elevation for Fanno Creek is identified at 140 feet in this vicinity. review of the plan and profile drawings (See Appendix) illustrates that a pproximately 523 lineal feet of sewer line and four manholes will be located within the 100- year floodplain. The majority of the project is located above the floodplain elevation. 2. Pan Designations The McDonald Trunk project is located entirely within the Regional Urban Growth Boundary (UGB) and within the City of Tigard. The project area is designated for Low Density Residential use to the west of S.W. Hall Boulevard, and the area east of Hall Boulevard is designated for Medium Density Residential use An Open Space Overlay applies to the Fanno Creek riparian corridor as illustrated on the project map. The City of Tigard Park Plan (1987) identifies the entire project alignment as a "Greenway," ' public g ` y or adopted plans for trail However, the City has not secured land for a reenwa improvements in this segment of the Fanno Creek Corridor extending west of Hall Boulevard: 3.

Natural Resources OTAK prepared a Wetland Functional Value Assessment and a Wildlife Habitat Assessment of the project area. Two copies of these reports are submitted with this land use application. An abbreviated description of the natural resources within the project area follows. The wetlands in the project area are associated with a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard. The tributary includes natural riparian areas as well as channelized drainage and diked pond areas. The stream is culverted under Hall Boulevard and continues east to Fanno Creek. As illustrated by the plan profile drawings, proposes . p the tributary, with portions of lan & rofile drawin s, line � USA to follow the path of ds and ponds in other the sewer line crossing wetlands in certain areas and avoiding wetlan p segments. Fanno Creek will be crossed at a 90 degree angle with 66 lineal feet of sewer pipe and the project will terminate approxiina Lely 100 feet east of Fanno Creek with a connection to an existing USA transmission main, The entire length of the stream flows through private lots.

OTAIC observed numerous species of birds irds using the project area for habitat, including: robins, jays, wrens, chickadees, finches, sparrows, ducks, and a red tail hawk. Evidence also exists to indicate that woodpeckers frequent the project area Bird activity is particularly heavy in the western potion of the project area Species not visually confirmed on site, but whose presence are suspected due to indicators include: frogs, newts, snakes, field mice, raccoons, possums and other small manimais. The re p ort concludes des that the sewer ewe r construction project is expected to have minor P t upon wildlife populations in the riparian area Opportunities for minimization of impacts exist and are identified in the report. Although the project will result in a temporary disruption of the wetland/riparian corridor 2 months), the ground contours will P � C ) ground restored and native plantings enhanced following construction. 1 HI. COMPLIANCE WITH COMPREHENSIVE PLAN AND COMMUNITY DEVELOPMENT CODE A. Tigard Comprehensive Plan .mom The McDonald sewer trunk will serve property located within the Urban Growth Boundary: The line has been designed and sized to accommodate development on the basis of land uses and densities established in the Tigard Comprehensive Plan. The Plan was adopted by the City of Tigard in November of 1983. The Land Conservation & Development Commission (LCDC) has acknowledged that the Tigard Comprehensive Plan complies with the statewide planning goals. The policies and findings of the Plan are implemented in the Community Development Code. The Plan does, however, provide an important context to evaluate code consistency: Pertinent policy statements from the Plan are ' highlighted I cy , in italic type below, with brief findings provided to describe why the proposed gravity sewer line is consistent with thee policy statements. 1. Floodplans and Wetlands The C shall prohibit any rise form alterations or develop which w �' P y f testa developments in the 100 -year floodplan Quid result in any rise in elevation of the 100-year floodplain. Findings: Only the easterly . g y ly portion of the proposed sewer line will be located within the Y P (below the sewer fine, 100-year flood lain below elevation of 140 feet After installation of th existing land contours will be restored and the project will not result in `any change i g in flood plain. of the seventeen manholes will be located within the 100 -year flood plain elevations, Three , p Thr lain: designed to be w of st rmwat�er i manholes will be g watertight to prevent. infiltration and inflow into the sanitary sewer system. 2. Natural Areas The City shall protect fish and wildlife habitat along stream corridors by managing the riparian n. dn dabitat and controlling erosion, and by requiring that areas o f standing trees and natural Vegetat ion along natural drainage co urse and Waterways be maintained to the maximum extent possible: Fin' ,i. ....�, t g ,. p . ,, ..p , p Y thin tributary to din sr '�'he 'VFlild ife habitat �e ort re are�� Panno Creek su orts varied urban wild this life but �TA�� notes that . � pP , .. fish � it will is not a � fish habitat, Fanno Creek, however, + does provide fish habitat and it will be very important to ensure careful construction practices to protect the fisheries value of Fanno Creek, „'d4,'. �' ,. �, `� ° -.'':i 9 ..��} 1” • ., 4 �: A.,+f 'w ' r 'FL.. 3 ,y,3 �w ''ve u. �'' x,; '.,0. Gravity sewer facilities are designed on the basis of a drainage system and of necessity follow lowland areas such as floodplains and drainage hazard areas. USA has selected an alignment and designed the project to minimize impacts on the riparian habitat area to the extent feasible. The alignment west of Hall . Boulevard avoids steeper slopes which are highly sensitive to erosion. USA has also made an effort to select an alignment which avoids large trees and ponds. The contractor will be required to implement an erosion control plan for the project. Additionally, restoration of disturbed areas will emphasize native plantings to enhance wildlife habitat values. USA will also direct the contractor to retain large snags within the temporary construction easement as suggested in the OTAK report. 3. Parks, Recreation and Open Space The City shall designate the 100 -year f oodplain of Fanno Creek it's tributaries, and the Tualatin River as Greenway, which will be the backbone of the open space system. Findings: The 1987 Tigard Parks Plan identifies the entire alignment of this project as "Greenway." Fanno Park has been secured as public open space between Highway 99W on the north and Hall Boulevard on the east. USA will not be buying the land for the sewer line alignment and is not in a position to "dedicate" the land as public open space. Additionally, the City of Tigard has not prepared plans for a public pathway in this segment of the Fanno Creek Corridor. Approval of the McDonald sewer trunk project will not compromise the designation or protection of the Fanno Creek tributary as Greenway 4. Public Facilities and Services The City shall prepare and implement a capital improvements program in conjunction with Washington County and the applicable service districts. Findings! The McDonald sewer trunk project is identified as a needed capital improvement project in the USA 5 -year capital improvement plan. Additionally, construction of this segment of sewer will allow the city to "activate" a dry sewer line that was installed in S.W. McDonald Street in 1992 as part of a coordinated street/faci 2. Public sewer (new development on septic tanks shall not be allowed within the City); and 3. Storm drainage. b. The facilities are: 1. Capable of adequately serving all intervening properties and the proposed development; and 2. Designed to City standards. c. All new development utilities to be placed underground. Findings: The McDonald trunk line will serve lands within the Regional UGB and the City of Tigard which are planned for urban development. Oregon's land use system requires that "urban" uses be served with full urban facilities, including public sewer. Existing uses in the project area which are on septic systems will have the opportunity to connect with the public sewer and connection to the sewer will be required for any new development. The sewer line has been aligned, sized and designed to serve all properties within this drainage basin and will provide a link of the McDonald Street sewer line with the transmission trunk east of Fanno Creek, USA has coordinated with the City of Tigard engineering department to ensure that the facility is designed to City standards: The City typically requires paved access to all manholes for maintenance. Given the sensitive character of the drainageway and the fact that the line will run through parcels, the City has agreed that the line can be maintained without the need for road access to the manholes, The 100 -y ear floodplain elevation as e s tablshed by the 1981 Flo od Insurance Study y conducted by the U.S. Army Corps of Engineers shall be protected. Finding: Only the easterly portion of the line close to Fanno Creek has a land contour below the 100 -year fioodplain elevation of 140 feet. After excavation and installa tion of the sewer line, the natural ground contours will be restored and there will be no fill or alteration of the 100 -year floodplain, Erosion control techniques shall be included as a part of the site development plan, F..in 3 USA is the stormwater management agency for Washington County and has responsibility for responsibility implementation of DEQ administrative rules mandating erosion control measures in the Tualatin River Basin, A specific erosion control p re will be lan 'p prepared f or the project per the `'Erosion Control p p Plans Technical Guidance Book, Following approval of the land use permit; USA will put the McDonald trunk project out to bid, The selected contractor will be required to adhere to the erosion control plan and use construction practices designed to minimize erosion, 11 1— ILI USA also anticipates that the Division of State Lands and the Oregon Department of Fish Wildlife will specify erosion control conditions for the sewer line crossing of Fanno Creek to protect water quality, fish and wildlife habitat values. The City shall adopt a clear and concise agreement with USA, implementing the City's policies for extending the availability of sewer services and encouraging the phasing out of septa tanks. Findings: The McDondald sewer trunk project is proposed for three primary reasons. First, construction of the gravity line will allow USA to take the McDonald pump station off line and avoid on- going costs associated with upgrading and maintaining the facility. Second, construction of the gravity line will provide the linkage needed to activate the "dry" sewer line in McDonald Street and transmit sewer flows to the Durham Treatment Plant. Third, the gravity line will provide the infrastructure to accommodate future development within the drainage basin and will also provide an opportunity to phase out existing septic tanks: In the development of new sewer systems, priority shall: a: First, be given to areas having health hazard problems which will be determined by DEQj and Second, be given to areas where the cost - benefits are the greatest in terms of the number of potential connections. g The project vicinity has not been designated problem by DEO Findings: vicinity ated a health hazard the Oregon Health Division because of failing septic s y stems. However, the project is a priority for USA and the City of Tigard because of the cost-benefits of a gravity system relative to continued use of he pump station and because of the number of potential connections existing and future) which will be served with this line connection. The City will coordinate with the Unified Sewerage Agency in the construction of new trunk and collector lines through both the City's and USA's capital improvement programs: Find n s USA has coordinated with the city of Tigard in the planning and desf ern for the � .g � p g ld trunk line: Representatives of the City of Tigard neighborhood McDonald i and attended nee hborhoo meetings with USA to discuss issues of connections to the new line, etc: The project cost is being funded through agency-wide capital improvement program ram rather than a local improvement district which zssigns costs to adjacent property owners: Energy The Clty shall encourage land use development which emphasizes sound energy conservation, design gn and construction: 12 Findings: The USA Facilities Plan identifies a preference for a gravity system over use of pump stations because of reduced energy costs, maintenance requirements and reliability. The McDonald pump station is old and would require upgrading to meet new EPA requirements such as a dual power source. When the new gravity line is constructed and the pump station removed, there will be no sewer pump stations remaining in the City of Tigard. 6. Greenway Park System Goal: To preserve the. riparian area of the Tualatin River, certain creeks and natural drainage smiles which will retain and improve livability of the community and serve the leisure and aesthetic needs of City residents. Findings: USA retained OTAK to perform wetland and wildlife habitat assessments of the project area The riparian area adjacent to Fanno Creek and the relatively undisturbed riparian area at the west end of the project are described as moderate -high value resources. .. , gn p . ip extent feasible. USA, has selected an alignment to minimize impacts to riparian areas to the extent , Additionally, landscape restoration is proposed to mitigate for the short -term construction impacts. The landscape plan emphasizes native plantings to diversify and enhance the riparian/habitat values of the drainageways Acquire remaining land in the greenway system through dedication or easements. Findings: USA will only acquire easements for the sewer line and will not have fee ownership of the property, Therefore, USA is not in a position to 'dedicate' the sewer line corridor to the City as a condition of the Sensitive Lands Permit. To preserve, protect and enhance plant, wildlife and fish areas and habitats; water areas, and wetlands. dings" i the OTAK wetland and habitat assessment reports the Findings: Multiple , As ocun�ented in , . . � ;, s an._. wetlan ri anan areas of this tributa to I'ann p ry a Creek. are valuable for functions. corridor for wildlife habitat, water quality, open . value of this cor space amenity, and o0 recognizes the v p ty flood d water storage, Although installation of the fine will involve a minimizes .. the .. . . p disruption of th area USA has selected an alignment tell temporary i p ` significant , g for the sewer line wh ` . vegetation nd en _ has demonstrated a commitment work with net hbors and resource and the Agency c}, s P neighbors r o rce agencies to mitigate for the temporary Impacts with landscape restoration. .',nhance landscaping where necesiiary with natural vegetation.

The following plantings are proposed as illustrated in the drawings in the Appendix: • Scouler Willow • Service Berry • Red Alder • Nootka Rose • Red-Osier Dogwood O Sputa clusters Woody plants (trees and shrubs) are planned where the soil is moist from creek saturation. Ground covers of meadow fescue, meadow foxtail, and clumping rye grass are proposed for soil stabilization and forb layer development in the westerly portions of the project. B. Tigard Community Development Code The chief function of the Community Development Code is to assist in the implementation of the Tigard Comprehensive Plan. The Development Code does not require a land use approval for installation of an underground sewer line. However, a Sensitive Lands Permit is required because the project will cross wetland/floodplain areas. 1. Application Process As noted earlier in this report, the Tigard Community Development Code states that a quasi-judicial land use application may be initiated by any of the following: 1.■ Tigard City Council (by order) Tigard Planning Commission (by resolut!on) Tigard Community Planning Director Application of recorded owners of property or contract purchasers Findings: USA will work with the affected property owners to secure easements for the sewer line, A 15 foot permanent sewer easement will be acquired, along with a wider temporary construction easement (typically 60 feet), However, USA will not become the owner of record of the affected property, USA will make every effort to work with affected property owners on the acquisition of easements, The Agency, however, does have authority to use condemnation if required, USA made an effort to obtain written authorizations from the affected property oWners to submit this land use application, A majority of the affected property owners (10 of 15) did return the authorizations, To avoid a procedural issue relative to the application process; USA obtained a letter from the City of Tigard authorizing the Planning Director to initiate the application as allowed by the Community Development Code, USA will pay all required • , , „,„„ 14 , • application fees and tiva decision on the Sensitive Lands Permit will be made by the Hearings Officer and not the Planning Director. 2. Sensitive Lands The City of Tigard has adopted a specific chapter in the Community Development Code to address sensitive lands (Chapter 18.84). Sensitive lands are described as lands potentially unsuitable for development because of their location within the 100 -year floodplain, within a natural drainageway, within a wetland area, on steep slopes, or on unstable ground. The sensitive land regulations are intended to maintain the integrity of the river, streams, and creeks in Tigard by minimizing erosion, promoting bank stability, maintaining and enhancing water quality, and fish and wildlife habitats, and preserving scenic quality and recreational potentials. The regulations are also intended to implement the flood insurance program and to maintain the September 1981 zero -foot rise f loodway elevation. A Sensitive Lands Permit is required for the McDonald Sewer Trunk project because of two categories of sensitive lands. First, the easterly 523 feet of sewer line, including four manholes, will be located at or below the 100 -year floodplain elevation of 140 feet. The sewer line will be placed in a trench, with natural contours restored following installation of the line. This easterly portion of the line represents the only segment where the natural ground contours are below the 100 -year floodplain elevation. Second, the ose ro d sewer line will cross or impact a drainageway and wetlands. Again, p P natural contours will be restored following construction and a landscape restoration plan implemented to mitigate for the construction impacts.* There will be no long -term fill, P development associated wit the sewer line However, the temporary s • ; ,cause o. removal, or with with weder, be i disruption associated wi the construction of the sewer line in a drainageway and wetlands, a Sensitive Lands Permit is required .. u fro m the City of Tigard and permits are also required uired from the Corps of Engineers/Division of State Lands. Pertinent standards and criteria of the Sensitive Lands Chapter are addressed below. 18.84.01 5 Applicability ,. abllty of Uses Sensitive Land Permits shall B. be obtained from the appropriate community development division for the following 1 Ins underground utilities and roadway improvements . � n o raadwa arrt roo�emet�ts M d cvrtstrtictto Installation of und�rgt including sidewalks, curbs, street lights, and driveway aprons, 2.

Land form alterations or developments within the 100-year floodplain shall be allowed only in areas designated as commercial or industrial on the comprehensive plan land use map, except that alterations or developments associated with community recreation uses, utilities, or public support facilities as defined in Chapter 18.42 of the Comh2unity Development Code shall be allowed in areas designated residential subject to applicable zoning standards. Eitglii_Lgi a: Installation of underground utilities within 100-year floodplains is clearly contemplated by this Code provision, As described above, pre-construction contours will be restored and there will be no long-term land form alteration, buildings or impervious surfaces associated with this project. 3. Where a land form alteration or development is permitted to occur within the floodplain it will not result in any increase in the water surface elevation of the 100-year flood; Findings: Given that pre-construction contours will be restored and manholes will be installed flush with the ground surface, this project will not result in any increase in the water surface elevation of the 100-year flood. 4. The land form alteration or development plan includes a pedestrian/bicycle pathway in accordance with the adopted pedestrianlbicycle pathway plan, unless the construction of said pathway is deemed by the Hearings Officer as untimely; Findings: USA will negotiate with property owners for a permanent 15 foot wide sewer easement for the McDonald sewer think. However, USA will not hold fee title to the land, The City of Tigard has not prepared plans or designs for a pedestrian/bicycle pathway in this portion of the Fanno Creek Greenway. It is therefore inappropriate and untimely to require that USA include a pedestrian/bicycle pathway within the sewer line easement as a condition of the Sensitive Lands Permit, The City of Tigard has the opportunity, if necessary, to negotiate with property owners for expanded use of the sewer easement for a recreational trail. 5, The plans for the pedestrian/bicycle pathway indicate that no pathway will be below the elevation of an average annual flood; FinOings: Based on direction from the City of Tigard, this Sensitive Lands Permit does not include any analysis of a pedestrian/bicycle pathway relative to floodplain elevations, The necessary US Army Corps of Engineers and State of Oregon Land Board) Division of State Lands approvals shall be obtained; and Findings: USA has obtained a nationwide permit from the Corps of Engineers for this pitied (See Appendix). Additionally, an application to t e of State Lands is pending for work within wetlands, USA understands that the City of Tigard will defer to 1 the Corps/DSL for permit authority and conditions relating to the work within the wetlands. A copy of the DSO, permit and conditions will be forwarded to the City following approval and USA understands that no work can begin until all of the regulatory approvals are in hand. 7 Where land f orm alterations and /or development are allowed within and adjacent to the 100 -year floodplain, the City shall require the dedication of sufficient icient 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 pedestrianlbicycle pathway within the floodplain in accordance with the adopted pedestrian /bicycle pathway plan. Findin a, The issue of the pathway has already been addressed.

The need to construct the gravity line to replace the McDonald sewer pump station is identified in the Agency's capital improvement plan. Additionally, because USA's regional system is largely designed on a gravity basis, transmission lines must of necessity follow creeks and lowland areas: In selecting the alignment for the project USA has taken steps to avoid impacts to significant trees and riparian areas. A detailed landscape restoration plan has been prepared to ensure that the natural resource values of this Fanno Creek tributary are enhanced and protected on a long- term basis.

During the field work for this project, OTAK's wetland biologist characterized and analyzed the wetland functional value along the corridor proposed for placement of the sewerline trunk. The wetland boundary and the four different types of wetlands along the length of the stream can be shown adequately and since the project will not impact more than a , narrow corridor within the drainage basin, the exact wetland boundary related to the width is not required for the mitigation plan. The placement of the sanitary sewerline within the stream corridor will impose minimal impacts to the wetland and any material removal will be replaced directly back in the wetland upon the completion of the construction. SITE rdESCRIPTION The site is located in Tigard, Oregon in the vicinity of the intersection of S.W. McDonald Street and Hall Boulevard. (Figure. I) The proposed trunk begins at McDonald Street and runs east along a tributary of Fanno Creek flowing east to Hall Boulevard. The proposed trunk continues east perpendicular to Hall Boulevard along a property easerneht to Fenno Creek. It crosses the creek and terminates approximately one hundred feet east were it ties into an existing sanitary sewer trunk, METHOD Site information was collected by OTAX's wetland biologist; Jack D. Dalton on SepteMber 4, 1993, Areas on either bide of the tributary to Fenno Creek and Fanno Creek were surveyed to ensure the review of all of the wetland areas in the vicinity of the proposed sewer title trtiiik, Subsequent to the background research; Mr, Dalton completed the proposed determination, evaluation, and mapping of the wetland titea. The t011oWing steps were itielUded: Project plans were reviewed, • Appropriate topographic, geological, and soil maps were consulted; • Recent aer!al photographs were reviewed; • On-site vegetation; soils, and hydrology were characterized, and Proposed determination and evaluation WAS Made: The deterinination..and .evaluation. tspott. have .beeri .pieepered in SOCOtiiiitioe With the ItOUtitie .Method and Atypical 8ituatiori.

Upon determination of the wetland indicators on site, an evaluation and delineation of the wetland boundaries has been prepared. As discussed before, the impacts from the proposed construction within the wetland area on site are confined only to the stream bed and along an upland section east of Hall boulevard. wetland For this reason, a boundary was not surveyed by locating flagging in the field. Instead the wetland i y field work preformed by Mr. Dalton which determined the boundary i® based upon the p by approximate boundary and shown on the 1 " =50° map prepared by Westlake Consultants, Inc. (See figures 2.5.) The areas impacted by the proposed activities can be located easily from the detailed topographic information. The stream is divided into four sections to aid in reference to the narrative. The functional value analysis has been preformed using the Wetland Evaluation Technique 2.0 (WET II) developed by the Federal. Highways and Army Corps of Engineers. 1'.

The growing season of the prevalent vegetation is loosely defined as the title in which a majority of the vegetation has begun to grow, generally between the months of March through September in the Pacific Northwest. Essentially, this means that the ground must be saturated between 8 to 12 consecutive days during this time for the criterion to be satisfied. The hydrological regime of this site includes a tributary of Fanno Creek flowing east from a ,culvert under McDonald Street to Hall Boulevard through a series of channelized and undisturbed draaages and diked ponds. The tributary flows under Hall and continues east through two more diked ponds and feeds into Fanno Creek. The entire a length of the stream flows through private lots. In some areas the stream has been allowed to expand and forms broad emergent marsh areas or the stream has been channelized into narrow ditches along the backside of lawns and under small bridges such as in the section between McDonald and Hall. The impoundments found periodically y g stream provide different habitat, but these are limited in size. 1 along the stye Only in a few short sections has the stream remained in its natural condition and the diversity of the vegetation in these areas reflect this observation: One of these sections is located west of Hall Boulevard and the other is along Fanno Creek itself on the eastern edge of the project site The U.S. Fish and Wildlife NWI characterizes four wetland types in the drainage system associated with this project. The stream west of Hall Boulevard is listed as palustrine, forested, broad -leaf deciduous, saturated `semipermanent\seasonal for most of the length except for the emergent areas listed as palustrine, emergent m persistent, arsh , sat uratedsemiper manent\seasonal. The dikedponds � rd are re listed as Palustrine ! open water, artificially flooded, intermittently ex p osed\p ermanent , diked\impounded. Fenno Creek is listed as riverine, upper perennial, open wa ter, intermittently exposed \permanent.(Figure 6.)

The primary soil types found on the study area are listed as having hydric soil characteristics in. Washington County. Field data collected supports this listing, which revealed that the soils found in the Wetland areas possess hydric soil indicators such as Soil mottling, loW chrome., and reducing conditions 417 i9 /watlarid,r'ep 11993:22 drigNIEMEEMCEMENUM......11.M2111 MCDONALD SANITARY SEWERLINE TRUNK - WETLAND DELINEATION REPORT MAK alCSIOMMIWOMMIN.. The soil on site along the stream basin is identified as Huberly silt loae the Soil Conservation Service (SCS) Soil Survey of Washington County. This s i is classified as being hydric by the SCS. This soil is generally located in concave surfaces in broad valley basins. It is a poorly drained soil formed in mixed silty alluvium and the permeability is slow. Runoff is slow to ponded and the hazard of erosion is slight. On either side of the stream basin the soil is identified as Quatama silt loam. This soil series is not documented as being hydric, however, inclusions of the hydric Huberly soil series are possible in this region. This soil is described as being moderately well drained forming in mixed, loamy alluvium on old terraces. The permeability is moderately slow and the hazard of erosion is slight. The soil forms on gently sloping terraces of 3 to 7 percent slope. Soil samples collected along the stream drainages have a chrome value indicated by Mansell Soil Color Chart values of 10YR 3/1-2/1, dark grey to black, with grey mottles of 10 YR 4/1-6/1. These samples revealed a medium to very fine texture. These values/chromas have proven to indicate hydric soil conditions, Other indicators such as organic streaking and reducing conditions further support this data Samples collected along upper edges of the stream basins typically were in the color chart range of 10YR 3/3-4/3, dark brown to light brown, with very little mottling. These samples revealed dry, fine to moderate textured soil, (Figure 7) Soil samples taken in the drainages along the road embankments revealed gravel, asphalt, and sand typically found in fill material for roads. These areas were along McDonald Street near the outflow of the culvert there and along the edges of Hall Boulevard in the drainage channels, 4110MotiiiiiLieti • • 0901,Z, 5 [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] • ■i■ r. • . 6 , ' 1 ' /4 ;PEPIIY•-t- • 'Ai' :,• . : . %. • .e- • I . 1/4• ... ••-.. c • 1 $901 i 1 ,..... ,.• , i ' '. r:luto, .)

Wetlands function as habitat for wildlife, as a storage place for floodwaters, or they can function to purify the water that moves through them. The level at which a wetland functions is termed its value or functional value. It is this value that the regulations intend to protect in the 'no net loss' rules. The wetland areas on this site were evaluated based on the WET II evaluation method. This method identifies 11 wetland functions (see Table 1) and provides the parameters to determine if these functions for a particular wetland area have a high, medium, or low value. Section 1 and 2: These sections are moderate to moderate-high. They are less disturbed in general than the assessed wetlands east of Hall Boulevard. Food chain support and wildlife habitat are both moderate to high. These functions remain, high due to the presence of essentially continuous habitat along the entire stream course providing a good structure both vertically and horizontally. The positioning of the emergent area directly adjacent to the mixed forest community provide higher diversity as a food source and greater habitat availability. Shoreline protection remains moderate and floodwater storage is moderate. The presence of lawn areas directly along the bank of the stream in these sections lower the ability of the wetland to absorb greater stream flow and don't contribute as much to the protection of the banks from erosion, The presence of the pond areas, however, adds value to the floodwater storage function. The groundwater recharge and discharge equal out in this type of drainage basin. The semi-permanent condition of the stream increases the ability of the discharge function and the slow permeability of the soils here limit the amount of recharge function. The periodic ponds along the drainage tend to increase the extent of the recharge and serves to limit the discharge, Functions contributing to water quality value in the drainage range from moderate to moderate-high due to the high density of the forb and shrub vegetative layers, Again, the presence of lawn directly in the saturation zone of the wetland tends to lower the water quality from levels found in emergent areas as well as contributes to the amount of nutrients and sediment which result from fertilization and ground disturbances on the lots along the stream. Section 3 and 4t These sections are moderate and slightly lower quality on the average compared to the h proposed other two sections, Also the wetlands within the ropo ed truk n line are smaller in acreage and this tends to lower the value, Food chain support and wildlife habitat are moderate high in function due to the continuous habitat in tree and shrub layer between the open meadow along Hall Boulevard and the forested corridor of Fenno Creek, Structure and habitat diversity contribute to both functions. Functions describing the stream course and the bank are difficult to assess within the easement because the proposed trunk/file crosses the Fallho Creek tributary and Farm° Creek td/wetliiiatiti 934Z 10 . . „ MCDONALD SANITARY SEWERLINE TRUNK - WETLAND DELINEATION REPORT OTAK these functions are valuable only when an entire length of stream bank or stream is assessed. There is a presence of vegetative structure contributing to the integrity of the bank. (See data sheet 13) The groundwater discharge is moderate -high due to the intermittently exposed /permanent condition of Fanno Creek and the lack of any ondin develop significant areas where ponding can p and contribute to the groundwater recharge. The remaining functions are low to moderate either due to the absence of significant amounts of emergent vegetation and the high degree of bank erosion on this portion of Fanno Creek. In these areas, the crossing must not impact the present condition of the stream banks, which specifically can be measured by the vegetation present, because the impacts would likely effect areas downstream in Fanno Creek.The minimal impact acreage results in lower mitigation requirement and if the construction is conducted appropriately the impacts to the drainage system will also be minimal. 47 t9 /wv th rid,rep 0993:22 11 '1,t Y ' ' :v Wit.. 6 ,� , [ 4 ■t,,k sj'" .7 . 1 TABLE 1.

Sewerage Agency (USA). In the original report, wetland functional values were evaluated for the proposed project impact areas. USA has since requested OTAK to provide further information regarding wildlife and wildlife habitat values associated with the project area long term p existing This additional evaluation will address short and ton terxn impacts on existin wildlife and provide additional information regarding the wetland mitigation plan. SITE DESCRIPTION The site is located in Tigard, Oregon in the vicinity of the intersection of S.W. McDonald Street and Hall Boulevard (Figure 1). The proposed trunk begins at McDonald Street and runs east along a small tributary of Fanno Creek to Hall Boulevard The trunk continues east, perpendicular to Hall Boulevard, along a property easement to Fanno Creek. It crosses the creek and terminates in approximately one hundred feet, where it ties into an existing sanitary sewer trunk. METHOD Site information was collected during two site visits, The brat was performed by Jack Dalton and John Lee (OTAK) for the purpose of evaluating remaining wetland mitigation issues and documenting wildlife use This occurred between the hours of 1.00 pm and 4:00 ram on March 22, 1994, The second site visit occurred between 9.30 am and 12:00 pm on March 24, 1994 p by , j potential and was performed b Michelle Wilson (OTAK) to assess otential wildlife impacts associated with the planned project. In performing this assessment, the following steps were included: • Project plans were reviewed; • The wetiand delineation report was reviewed, • Recent topographic maps were consulted; • Wildlife habitat, cover, and food values were characterized; 0' A list of wildlife species present on the site or thought to be present on the site was compiled; assessment of potential ..

Where possible, the general habitat types have been discussed in relationship to the wetland value data previously collected (Data Forms, Appendix A). Section 1 This section, which contains the highest quality wildlife habitat of the project area, extends east from McDonald Street to the private sports court area located downstream (Figure 2). The western portion of this section contains a narrow stream which emerges from a culvert passing under McDonald Street. The stream opens into an emergent wetland, filled with reed canarygrass and Himalayan blackberry, and is surrounded by a mixed forest with a diverse understory, The proximity of this forest to the emergent wetland enhances the value of this site, as does the presence of numerous standing dead trees (snags). The habitat diversity in this area is demonstrated, by the concentration of numerous bird species. The dense forest canopy and the understory shrub layer provide good structure and diversity, resulting in excellent habitat valdes, The forb layer, mostly intact at the time of this visit, contributes to the high habitat and forage values. At the eastern edge of the meadow, the stream becomes confined to its channel again as it passes through a light forest into a residential area The homes located on the north side of the creek have impacted habitat value, The stream has been channelized in this area and several small dikes have created ponds adjacent to residential backyards. As the creek moves east toward the sports court, dominant hydrophytic vegetation (skunk cabbage) is replaced by lawn grasses, Bare soil and a barking dog also detract from habitat value in this area However, the southern side of the creek remains a mixed deciduous forest) whose presence helps to preserve some of the habitat values in this area This forest provides linkage between the high quality habitat upstream and the moderately high quality area downstream, The understory arid forb layers in this forest are minimal, Section 2 The stream is channelized in this area, with bare banks and minimal vegetation present on the western portion of the site (Figure 3). The first of two ponds lacks adjacent vegetation and 18 low in habitat value, Another pond area just downstream, offers more significant opportunities for wildlife, The banks of this pond are well protected by hydrophytic vegetation and the area demonstrates high structure and diversity values for amphibians, birds, and small mammals, Water quality in this pond is moderate, with fairly high turbidity levels. The pond 8tibstrate is composed prirnarily of silt and organic; material, Terrestrial vegetation in this area is diverse, including bamboo, dattallg, sedges, mixed deciduous tree species, and several significant snags, • 13;\411Aftiki3Xtis' 404,i6 3 [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] s�.r _:. ...... i...- ....- �..�.. ... _ _� -. .. . <. .c. ..._ _ . 4.¢ , -rv- - .. w A . .. 1. -'S .

This forest contains mixed deciduous and coniferous species and the shrub layer ranges from intact to absent. Several large western red cedars exist in this area Wildlife cover, nesting, and escape values are moderate to high here, and the presence of food and a consistent water supply further add to the value of this portion of the riparian corridor. Upon emerging from this forested area, the stream flows into a large pond with rip-rapped banks. The pond is surrounded by mowed lawn grasses and has the feel and appearance of a back-yard water feature, The proximity of this feature to residences makes it unlikely that it support much wildlife, with the exception of ducks. The pond has a silty substrate dominated by decaying organic material and the water quality is moderate to poor, Vegetative diversity is low, food values are low to moderate, and the pond is exposed and lacks significant cover. Section 3 The pond terminates in a culvert, which carries stream flow under a fence and into a rip- rapped channel in another back yard (Figure 4), The habitat values in this area are very low, as the dominant vegetation consists almost exclusively of mowed lawn grasses and the creek is fenced and culverted as it passes through tnultiple private property lots. Hall Boulevard provides an effective barrier to all wildlife species traveling along the creek, with the exception of bird species. After passing under Hall Boulevard) via a culvert, the creek flows into an open field) where it is again ponded, This and is not in the proposed project area, which lies just north of the pond along a public easement, This easement runs along a fence line separating an open field from a row of trees. Habitat values are low to moderate in this area due to disturbance, proximity to the road) and lack of vegetative structure and diversity, Section 4 The proposed trunk line continues east along the fence line to Fanno Creek (Figure 5). The western portion of this section is overgrown with shrubs and blackberry, which almost completely conceal the small stream, The stream resembles a shallow drainage ditch and exhibits low to moderate habitat values. This meadow is bordered to the north by a large pond) which retains significant trees along its perimeter, The trunkline easement however, is South of this area.

WILDLICFE Numerous species of birds were observed using the project area for habitat, including; robins, jays, wrens, chickadees, finches, sparrows, ducks, and a red tail hawk (Table 1). Evidence also exists to indicate that woodpeckers frequent the project area Bird activity is particularly heavy in the western portion of the site Species not visually confirmed on site, but whose presence are suspected due to indicators • include newts, , , mice, r, raccoons, possums and other small mammals.

In addition, fish species known to be present in Fenno Creek include: cutthroat trout, crappie, red -side shiners, bluegill, carp, dace, sculpin, three-spine sticklebacks (Tualatin Fish and Water Quality Reports DEQ 1987). SHORT 'TERM IM ?ACTS/mrITIGATION OPPORTUNITIES Removal of Vegetation Removal and damage of vegetation during construction is an unavoidable impact associated with this project: However, many of the points located along the proposed alignment are dominated by invasive vegetative species: Removal of these species is expected to have a low to modera g`mp upon habitat values, These impacts can be mitigated for by replacement veg etation that is hi g her in wildlife forage, cover, and habitat value.

Impacts to small mammals and bird species are expected to be minimal. LONG TERM IMPACTS Long term impacts associated with the proposed project are expected to be minimal to non- existent in their effects upon wildlife. Impacts resulting from installation of the sewer line can be effectively mitigated for and minimized through cautious planning: The impacts associated with long term maintenance and sewer line repair are not expected to pose a threat to wildlife or habitat values, provided that heavy equipment is kept out of the riparian area However, long term impacts would be anticipated if an access road or trail system were developed in the riparian corridor, Habitat values along this site are somewhat fragmented and placement of such a structure, without habitat mitigation, could further add to this fragmentation, Similarly, the increase in human activity levels associated with the improved access and physical habitat disturbances would detract from the current wildlife habitat value.

The western lo t line of 1500 is not drawn in on profile. This produced much confusion for property owner Nancy Young. Ms. Young also spent much time with Greg Barry and Terry discussing moving alignment south, closer to her property. After much discussion, we agreed that we could move it line south by moving manhole 16. Sue Vincent is concerned about a tree that was planted at the birth of her son. Our plans avoid it, but we should keep a close eye on it. Told he we would note its location in easement negotiation. Questions: What effect Will trench have on earthen dame near Hall Blvd? Contractor wil/ be below it and should not impact it at all. Has there been a cost analysic of this project versus upgrading pump station? How long will the project last? 3-4 weeks Where would equipment come in from? It is up to contractor, probably from both ways. If another way is needed, the contractor will secate. 1 have a fence, how long until the fence is replac ed and how will it be replaced? e . Contractor will either restretch fence or replace. Conditions of contract call for replace in "aS good or better condition," What are restrictions on easements? No buildings may be placed on permanent easementS, but dtiveways, sidewalks, parking may. How high will manholes be? We can make them flush, but may be a foot aboVe ground in Some areas. All will have water-tight lids. What', guarantees do we have the contractor will abide by contract? USA will have construction inspedtors and retains b percent of payment Until work is cotpleted approved, Will USA replace ornamental plants in my yard? Yes Do you take before pictures? USA prefers to video site before works, begins. What about replacement of top soil We can ask contractor to put 12 inches of top soil back on top after work is completed although they don't like to do this. Will USA put Ts in for tie in from properties? That's up to the city of Tigard. If Tigard wants y • g g and is willing to pay then USA will install. We would prefer putting in a T and 10 feet of pipe. What about putting in T as part of easement arrangement? What about trade of easement for connection? It is Agency policy to keep connection fee and easement compensation separate. What are costs of hooking up?

INTRODUCTION A. Description of Project The Unified Sewerage Agency (USA) is requesting City of Tigard approval of a Sensitive ,Lards Permit to remove the McDonald sewer pump station and install a gravity sewer line extending from S.W. McDonald Street on the southwest to an existing USA transmission main on the northeast side of Fanno Creek. Construction of this project will allow the city to activate the dry line installed in McDonald Street in 1992 and will convey sewage by gravity flow to the Durham Wastewater Treatment Plant. The project involves construction of approximately 2,717 lineal feet of 8 inch plastic sewer line. Elevations range from approximately 178 feet on the west where the new line will tie in with the existing 8" sewer in McDonald Street to approximately 120 feet on the east side of Fanno Creek where the gravity line will tie in with the existing 60" USA transmission main to the Durham Treatment Plant. Existing contours will be restored following construction of the sewer line. The project will also involve installation of 17 manholes as illustrated on the plan & profile drawings. As part of the update of the USA Facilities Plan, the a g en cy valuated all ll p u p stations for compliance with EPA standards (dual power grid, etc.) The existing McDonald pump station is old and USA concluded that it would cost less to remove the pump station and construct a new gravity line relative to the cost associated with upgrading and maintaining the pump station, including power requirements, When this pump station is removed, there will be no sewer pump stations remaining in Tigard. The McDonald Trunk Project is included in the Unified Sewerage Agency 5 -Year Capital ed alignment for the new 8 inch gravity sewer line is Improvement Plan. o os drawings are included The hep p �+ . g .. illustrated on the following exhibit.

The process involves public notice and a hearing and decision by the Tigard Hearings Officer, Based on the letter from the City of Tigard, no other local land use permits are required for the project. Representatives of USA met on two occasions with Tigard planning staff to discuss submittal . . letter, noted that requirements for the Sensitive Lards Permit In a follow-up letter staff of the q p the City has no immediate plan, to develop a trail design or alignment for this portion Greenway Trail System, it is premature to have the USA landscape replacement plan address impacts to future bicycle or pedestrian trails. Additionally, the City confirmed that they will accept maintenance responsibilities for the facility after construction even though there will be no paved access to the manholes. To provide input to the sewer line alignment and the Sensitive Lands Permit, USA hired OTAK to prepares a determination and evaluation of the wetlands associated with the project site.

Applicant The Unified Se aerage Agency (USA) is acting as the applicant for this project. USA is securing all required permits and will also provide oversight of the project construction. The project is being funded through the Agency'scimprovement program rather than a local improvement district. Following construction, the City of Tigard will assume maintenance responsibility for the sewer line. USA was formed as a county service district in 1970 to assume responsibility for wastewater treatment in response to a growing need for a regional water quality management framework in the Tualatin River basin. Prior to the formation of USA, a number of smaller districts provided sanitary sewer service in Washington County communities. USA constructed two regional wastewater treatment plants at Durham and Rock Creek to replace numerous older facilities which were not providing an adequate level of wastewater treatment: USA maintains and operates all of the municipal treatment plants that discharge to the Tualatin River. USA also constructs and maintains all "regional" trunk facilities. Cities within the USA district typically construct and maintain "local" sanitary sewer collector facilities within their jurisdictions. 18.32.040 of the Tigard Community Development Code states that a quasi judicial land use . .. application may be initiated by any of the following. L Order of Council; 2. Resolution of a majority of the Planning Commission; 3. The Community Development Director;. 4. Application of a recorded owner of property or contract purchasers: At the direction of Tigard staff, USA made an effort to obtain authorizations for this land use pp from i the 15 property owners affected by the project. USA obtained authorizations from p .. _ ... m 10 of the 15 property owners. Given that USA has condemnation authority to obtain easements if necessary, and given the efforts of USA to work cooperatively with property owners in the area, the Director authorized this Sensitive Lands Permit with Section 1832.040 y . � (3) Community Development rmit a 1�cat�on in accordance wit Code. A copy of the letter � of the Commu ,. py er from Dick Bewersdorff noting the authorization by the Director is enclosed in the Appendix. C. Public Involvement Process USA conducted two neighborhood meetings with the property owners affected by the. proposed McDonald trunk project (February 15, 1993 and November 18, 1993). Notice of The initial meeting the. two meetings was mailed in advance to affected property owners. g included a discussion of the need for the project and highlighted issues the property owners wanted USA to consider in the project design. At the second meeting, USA shared the proposed design and OTA:K wetland report. Additionally, input was requested on the proposed landscape restoration plan. Summary notes of the two neighborhood meetings are included in the Appendix. Elements of the project design have been modified in response to input from neighbors. In particular, USA has, attempted to align the sewer line to minimize the need to cut large trees and avoid impacts on existing ponds. In April of 1994, USA mailed out letters to affected property owners requesting authorization to submit this land use application to the City of Tigard. To date, USA has received written authorization from 10 of the affected property owners. A copy of the letter from USA requesting authorizations for the land use application is also included in the Appendix. In February of 1994, Mark Jockers of USA spoke with Liz Newton of the City of Tigard regarding the need to take this project to the South Citizen Involvement Team. Because of the small area involved, Ms: Newton recommended working directly with the affected neighborhood as USA has done. . II ilw t•rt � a5 �..r r Y �F4ar i �.. �... ., II. GENERAL INFORMATION o_ eTION A. Vicinity Conditions 1. Location & Land Characteristics The McDonald Trunk project covers a distance of about one -half mile, extending from S.W. McDonald Street on the west to about 100 feet east of Fanno Creek. Elevations range from 178 feet Mean Sea Level (MSL) on the west end of the project to a little above 120 feet MSL on the east. The 100 -year flood elevation for Fanno Creek is identified at 140 feet in this vicinity. A revve°s of the plan and profile drawings (See Appendix) illustrates that approximately 523 lineal feet of sewer line and four manholes will be located within the 100- year floodplain. The majority of the project is located above the floodplain elevation. 2. Plan Designations The McDonald Trunk project is located entirely within the Regional Urban Growth Boundary (UGB) and within the City of Tigard. The project area is designated for Low Density Residential use to the west of S.W. Hall Boulevard, and the area east of Hall Boulevard is designated for Medium Density Residential use An Open Space Overlay applies to the Fanno Creek riparian corridor as illustrated on the project map. The City of Tigard Park Plan (1987) identifies the entire project alignment as a "Greenway." However, iowever, the City has not secured land for a public greenway or adopted plans for trail improvements in this segment of the Fanno Creek Corridor extending west of Hall Boulevard, 3. Surrounding Land Uses Properties abutting the proposed McDonald Sewer Project are largely developed with single family dwellings, ng s - - o erties take access from Edgewood Street, McDonald Street and Hall , i'r p g + Several parcels . larger than the minimum lot size established by zoning and Faulevard. k els are i there is potential for lnhil residential development in the vicinity.

Natural Resources OTAK prepared a Wetland Functional Value Assessment and a Wildlife Habitat Assessment of the project area Two copies of these reports are submitted with this land use application. An abbreviated description of the natural resources within the project area follows. The wetlands in the project area are associated with a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard. The tributary includes natural riparian areas as well as channelized drainage and diked pond areas. The stream is culverted under Hall Boulevard and continues east to Fanno Creek. As illustrated by the plan & profile drawings, USA proposes to follow the path of the tributary, with portions of the sewer line crossing wetlands in certain areas and avoiding wetlands and ponds in other segments. Fanno Creek will be crossed at a 90 degree angle with 66 lineal feet of sewer pipe and the project will terminate approximately 100 feet east of Fanno Creek with a connection to an existing USA transmission main. The entire length of the stream flows through private lots. In some locations the stream has been allowed to expand and forms broad emergent marsh areas or the stream has been channelized into narrow ditches along the backside of lawns and under small bridges. The stream retains its natural riparian character in only a few segments, primarily at the western end of the project: The vegetative communities along this Fanno Creek tributary are comprised of a mixed forest of deciduous and coniferous trees with some areas possessing an emergent or open water component, Douglas fir, big -leaf maple, willow species, red alder and Western red cedar are found within understory shrubs, ced ' hn the mixed forest, The understo of shrubs small trees, and fortis vary in the project area depending upon the condition of the hydrology and the extent of human disturbance: Wetlands to the west of Hall Boulevard are less disturbed in general than the wetlands east of Hall Boulevard: Food chain support and wildlife habitat are both moderate to high due to the c resene o p of essentially continuo - g +: provides � a us habitat along the stream course which good structure both vertically and horizontally: The presence of lawn areas directly in the saturation zone of the wetland tends to lower the water quality functions as a consequence e of ground disturbance and fertilization on the lots along the streams: Drainage ditches and open meadow areas p The var Th. the drainage ditches nd surrounding lithe culverted crossing ais minimal, North vegetation in i g of the sewer line, the stream continues i p side (hawthorn; s out of a diked and A row of e parallels the oe th e a rohosed Oregon ash and willow mixed with blackberry) par is h north si of h proposed sewer line further east until it reaches the west bank of Fanno Creek: Fanno Creek is dominated by red -osier dogwood, willow, Oregon ash with a mix of red alder, hawthorne, ■ • v r r r ;mow himalayan blackberry, and Pacific ninebark, with scotchbrooni lining the banks.

Tigard Comprehensive Plan The McDonald sewer trunk will serve property located within the Urban Growth Boundary. line designed development on the basis of land The line has been desa ed and sized to accommodate Plan. The Plan was adopted uses and densities established in the Tigard Comprehensive by City Tigard ewith h, the �x of 'Ta and in November of 1983. The Land Conservation & Development Commission (LCDC) has acknowledged that the Tigard Comprehensive Plan complies with the statewide planning goals, The policies and findings of the Plan are implemented in the Community Development Code. The Plan does, however, provide an important context to evaluate code consistency. Pertinent policy statements from the Plan are highlighted in italic type below, with brief findings provided to describe why the proposed gravity sewer line is consistent with thee policy statements, 1. Floodplains and Wetlands The City shall prohibit developments in the 100-year floodplain ��' p � any ► f an land form alterations or d ear ood loan: which would result in any rise in elevation of the 100 -year fl p Findin s Only the easterly ortion of the proposed sewer line will be located within the y p (below � of the sewer line, After installation 100-year flood lain below elevation of 140 feet). project will not result in any change in and the r y Y g i .. ° .. seventeen manholes will be located within the 100-year existing land contours will be restore a floodplain elevations= Three of the floodplain, The manholes will be designed to be watertight to prevent infiltration and inflow of stormwater into the sanitary sewer system, 2. Natural Areas The City shall p rotec� hand wildlife l_ abat at along stream corridors y� managing the riparian habitat and controlling erasion, and by requiring that areas of standing trees and natural vegetation along natural drainage and waterwa y s be maintained to the maximum extent possible. s; The Wildlife Habitat Report repared by OTAK notes es that this tributary to Fanno Creek su pp orts varied urban t ._ dlafe, but is not a fi sh hab itat= Vann() Creek; does provide ash habitat and it will be very important to ensure careful construction p ractices to protect the fisheries value of Fanno Creek= Gravity sewer facilities are designed on the basis of a drainage system and of necessity follow lowland areas such as floodplains and drainage hazard areas. USA has selected an alignment and designed the project to minimize impacts on the riparian habitat area to the extent feasible The alignment west of Hall Boulevard avoids steeper slopes which are highly sensitive to erosion. USA has also made an effort to select an alignment which avoids large trees and ponds. The contractor will be required to implement an erosion control plan for the project. Additionally, restoration of disturbed areas will emphasize native plantings to enhance wildlife habitat values. USA will also direct the contractor to retain large snags within the temporary construction easement as suggested in the OTAK report. 3. Parks, Recreation and Open Space The City shall designate the 100 year floodplain of Fanno Creeds it's tributaries, and the Tualatin River as Greenway, which will be the backbone of the open space system. Fi,]_tid ngs The 1987 Tigard Parks Plan identifies the entire alignment of this project as "Greenway."

Second, gravity provide g "dry" _. construction of the rave , line. will .rovide the linkage needed to activate the d sewer line in McDonald Street and transmit sewer flows to the Durham Treatment Plant. Third, the gravity line will provide the infrastructure to accommodate future development within the drainage basin and will also provide an opportunity to phase out existing septic tanks. In the development of new sewer systems, priority shall: a. First, be given to areas having health • hazard problems which will be determined by D,��,• gx g �' and Second, be given to areas where the cost - benefits are the greatest in terms of the nuanber of potential connections, Findings: The project vicinity has not been designated a health hazard problem by DEO of failing septic systems: However, project is ox the Oregon Health Division because o - the . a priority for USA and the City of Tigard because of the cost benefits of a gravity system A relative to continued use of the pump .sng uic .. will be served with this line connection. because of the number of potential connections (existing and future) which n The City will coordinate with the Unified Sewerage Agency ' an the construction of new trunk and Collector lines through both the City's and USA's capital improvement programs. Findings, USA has coordinated with the Cl of Tigard in the planning and design for the _ City . Tig McDonald trun k line, . Representatives of the City of Ti gard a tte n ded neighborhood meetings with USA to discuss issues of connections to the new line, etc. The project cost is being funded thr ou gh the agency-wide c apital improvemen t program rather than a local improvement district which assign s costs to adj acent property owners: 5. Energy The City shall encourage land use development which emphasizes sound energy conservation, design and construction. 12 ,Findings: The USA Facilities Plan identifies a preference for a gravity system over use of pump stations because of reduced energy costs, maintenance requirements and reliability. The McDonald pump station is old and would require upgrading to meet new EPA requirements such as a dual power source. When the new gravity line is constructed and the pump station removed, there will be no sewer pump stations remaining in the City of Tigard. 6 Greenway Park System Goal: To preserve the riparian area of the 714alatin River, certain creeks drainage leisure and certain ere,, and natural rains e males which will retain and improve livability of the community and serve aesthetic needs of City residents.

Therefore, USA is not in a position to dedicate the sewer line corridor to the City as a condition of the Sensitive Lands Permit. To preserve, protect and enhance plant, wildlife and fish areas and habitats; water areas; and wetlands. Findings: As documented in the OTAK wetland and habitat assessment reports, the wetlands and riparian areas of this tributary to Fanno Creek are valuable for multiple functions.

Tigard Community Development Code The chief function oLthe Community Development Code is to assist in the implementation of Comprehensive Plan. The Development Code does not require a land use f the oval Tigard Compr pp for installation of an underground sewer tine: However, a Sensitive Lands Permit is required because the project will cross wetland /floodplain areas: 1.

Sensitive Lands The City of Tigard has adopte a specific chapter in the Community Development Code to address sensitive lands (Chapter 18.84). Sensitive lands are described as lands potentially unsuitable for development because of their location within the 100 -year floodplain, within a natural drainageway, within a wetland area, on steep slopes, or on unstable ground. The sensitive land regulations are intended to maintain the integrity of the river, streams, and creeks in Tigard by minimizing erosion, promoting bank stability, maintaining and enhancing water quality, and fish and wildlife habitats, and preserving scenic quality and recreational potentials. The regulations are also intended to implement the flood insurance program and to maintain the September 1981 zero -foot rise floodway elevation. A Sensitive Lands Permit is required for the McDonald Sewer Trunk project because of two categories of sensitive la First, easterly 523 feet of sewer line, including four . lands. . First the easterl 5�3 f manholes, will be located at or below the 100-year floodplain elevation of 140 feet. The sewer line will be placed in a trench, with natural contours restored following installation of the line. This easterly portion of the line represents the only segment where the natural ground contours are below the 100 -year floodplain elevation: Second, the proposed sewer line will cross or impact a drainageway and wetlands,+ Again, natural contours will be restored following construction and a landscape restoration plan implemented to mitigate for the construction impacts. There will be no long -term fill, removal, development associated with the sewer line: However, because of the temporary disruption associated � assoc�at va or eve o me 9 p ' line m a drainageway and wetlands. ththeco construction of the sewer.,. a Sensitive Lands Permit is required from the City of Tigard and permits are also required from the Corps of Engineers/Division of State Lands, Pertinent standards and criteria of the Sensitive Lands Chapter are addressed below, 18.84.015 Applicability of Use B, Sensitive Land Permits shall be obtained from the appropriate community development' division for the following' 1, Installation o f underground , r utilities and construction of roadway improvements including sidewalks, curbs, street lights, and driveway aprons; Minimal disturbance(s) round gr but no landfonrt alteration; 15 Find` l�ngs: USA is submitting this application to install an underground sewer line in a designated sensitive lands area ( floodplain /drainageway/wetland). The Community Development Code clearly contemplates that permits may be issued for underground utilities and roadway improvements. Construction of the sewer line will result in minimal ground disturbance, with an approximately 2 month disruption within a 60 foot wide construction corridor. Following construction, USA will restore the natural landform contours and will maintain a permanent 15 foot sewer easement in the project corridor. C 1 andform alterations or developments within wetland areas that meet the jurisdictional requirements and permit criteria of the U.S. ,Army Corps of Engineers, Division of State Lands, Unified Sewerage Agency, and /or other federal, state, or regional agencies do not require a sensitive lands permit. All other applicable City requirements must be sate; fed, including sensitive land permits for areas meeting non - wetland sensitive land citeriai Fin,ding This section implies that a separate Sensitive Lands Permit from the City of Tigard is not required equired if other regulatory agencies (Corps/DSL) have approved permits for the work in the wetland area The Corps of Engineers has issued USA a nationwide permit project (See An application to the Division of State Lands is,p gi for the ro ect See u Jat findings must Based on direction provided by Dick Bewersdorff of the Planning Department, g address sensitive lanf ds criteria pertaining to it ®od p loins and draiaa g e.. vsa ys : The City will d efer to th e Corps/DSL on the wetland permit and sep arate findings are not req uired to address wetlands through the sensitive lands permit, 18.840040 Approval Standards The Hearings Officer shall approve or approve with conditions an application request within the 100 -year floodplain based upon findings that all of the following criteria have been satisfied: 1.

Findings: Installation of underground utilities within 100 -year floodplains is clearly contemplated by this Code provision. As described above, pre - construction contours will be restored and there will be no long -term land form alteration, buildings or impervious surfaces associated with this project. 3. 1l'here a land form alteration or development is permitted to occur within the floodplain it will not result in any increase in the water surface elevation of the 100 year flood; Finding Given that pre - construction contours will be restored and manholes will be installed flush with the ground surface, this project will not result in any increase in the water surface elevation of the 100 -year flood, 4.

SUMMARY Based on the information contained in this report and the plans and reports included in the Appendix and submitted with the application, USA encourages City of Tigard approval of the Sensitive Lands Permit. wee The McDonald sewer trunk is needed to accommodate existing and anticipated growth based on adopted land uses and densities identified in the Tigard Comprehensive Plan. The need to construct the gravity line to replace the McDonald sewer pump station is identified in the Agency's capital improvement plane Additionally, because USA's regional system is largely designed on a gravity basis, transmission lines must of necessity follow creeks and lowland areas. In selecting the aliranent for the project USA has taken steps to avoid impacts to significant trees quo riparian areas. A detailed landscape restoration plan has been prepared to ensure 'that the natural resource values of this Fanno Creek tributary an: enhanced and protected on a long- term basis. 1 20 • M+K; •6 , .y y" -',� a'a "fir: 'Ajrv;�p'- rt APPENDIX Al - Plan & Profile Drawings A -2 Landscape Plans A -3 OTAK Wetland Assessment Ai -4 OTAK Wildlife Habitat Assessment A•5 Public Meeting Summaries A-6 Planning Director Authorization A-7 Army Corps of Engineers Permit LEGIBILITY STRIP' [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] LBGIBILiTY STRIP is [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] e ••"" W ' `'. j4.,,,,,'. y " ',V..,...":',,,,, , h , -:. ,'44. r .IN, J-11 y,, ,. .4 {i f r. k.

The tributary flows under Hall and continues east through two more diked ponds and feeds into Fenno Creek. In this report, the streams are divided into four sections to ensure the greatest accuracy and clarity in the assessment. The wetland boundary and the different types of wetlands along the length of the stream were shown adequately on a detailed topographic map.

During the field work for this project, OTAK's wetland biologist characterized and analyzed the wetland functional value along the corridor proposed for placement of the sewerline trunk, The wetland boundary and the four different types of wetlands along the length of the stream can be shown adequately and since the project will not impact more than a , narrow corridor within the drainage basin, the exact wetland boundary related to the width is not required for the mitigation plan. The placement of the sanitary sewerline within the stream corridor will impose minimal impacts to the wetland and any material removal will be replaced directly back in the wetland upon the completion of the construction. SITE »ESCRIPTION The site is located in Tigard, Oregon in the vicinity of the intersection of S.W. McDonald Street and Hall Boulevard. (Figure. 1) The proposed trunk begins at McDonald Street and runs east along a tributary of Fanno Creek flowing east to Hall Boulevard. The proposed trunk continues east perpendicular to Hall Boulevard along a property easement to Fanno Creek. It crosses the creek and terminates approximately one hundred feet east were it ties into an existing sanitary sewer trunk. METHOD Site information was colleted by OTAK's wetland biologist, Jack D. Dalton on a September 4, 1993. Areas on either side of the tributary to Fenno Creek and Fanno Creek were surveyed to ensure the review of all of the wetland areas in the vicinity of the proposed sewer fine trunk. Subsequent to the background research, Mr, Dalton completed the proposed determination, evaluation, and mapping of the wetland area The following steps were included: • Project plans were reviewed; • Appropriate topographic, geological, and soil maps were consulted, • Recent aeriai photographs were reviewed; , „ • On-site vegstation, soils, and hydrology were characterized, and • Proposed determination and eal vuat w m ion as ade. _ The determination and evaludtioh tepott bate beet) prepared in accordance with the Routine Method and Atypical Situation Method found ih the 1087 Corps orgiteitteert Wellatid Delineation Manual, The Routine method was used rather than the Intermediate Method which uses transect hnes, because the wetlands are pthilarily 4110/woitinaioo. 69.90.2. MCDONALD SANITARY FJE TRUNK - WETLAND DELINEATION REPORT OTAK associated with a stream channelized, the boundaries of wvhich can be located relatively easily by analyzing the topography of the area. Upon determination of the wetland indicators on site, an evaluation and delineation of the wetland boundaries has been prepared. As discussed before, the impacts from the proposed construction within the wetland area on site are confined only to the stream bed and along an upland section east of Hall boulevard. For this reason, a wetland boundary was not surveyed by locating flagging in the field. Instead the wetland boundary is based upon the field work preformed by Mr. Dalton which determined the approximate boundary and shown on the 1 " =50' map prepared by Westlake Consultants, Inc. (See figures 2 -5.) The areas impacted by the proposed activities can be located easily from the detailed topographic information. The stream is divided into four sections to aid in reference to the narrative. The functional value analysis has been preformed using the Wetland Evaluation Technique 2.0 (WET II) developed by the Federal Highways and Army Corps of Engineers �7�s%v:►e��aidr®p 099322 St1.Q..., FIGURE le LOCATION OF SITE SITE ViciNITY MAP • Oa:intim m locnrpoeated 7356SWBoo s�d.,LakeOW gOOR (5°3 s3538ie ak, a;,d b , i 97x53, MCDONALD SANITARY SEWERL!NE TRUNK - WETLAND DELINEATION REPORT OTAK WETLAND HYDROLOGY In order for the hydrologic criterion for a jurisdictional wetland determination to be satisfied, there must be enough water in a given area to saturate the soils within 12 inches of the surface for a duration of no less than 5% of the growing season. The growing season of the prevalent vegetation is loosely defined as the time in which a majority of the vegetation has begun to grow, generally between the months of March through September in g p Essentially, this means that the ground. the Pacific Northwest. must be saturated between 8 to 12 consecutive days during this time for the criterion to be satisfied. The hydrological regime of this site includes a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard through a series of channelized and undisturbed drainages and diked ponds. The tributary flows under Hall and continues east through two more diked ponds and feeds into Fanno Creek. The entire length of the stream flows through private lots. In some areas the stream has been allowed to expand and forms broad emergent marsh areas or the stream has been a se long the backside of lawns and under small l bridges such as in the section between McDonald and Hall. The impoundments found periodically along the stream provide different habitat, but these are limited in size. Only in a few short sections has the stream remained in its natural condition and the diversity of the vegetation in these areas reflect this observation. One of these sections i is located west of Hall Boulevard and the other is along Fanno Creek itself on the eastern edge of the project site. The U.S. • . zes four wetland types in the drainage system associated with this project '' Wildlife NWI characters yp g project.

The vegetation covering the majority of the delineated site is categorized as obligate wetland, facultative wetland, or facultative in the National List of Plant Species That Occur in Wetlands: 1988 National Summary. Facultative vegetation, the minimal vegetational wetland classification, is defined as plants found in wetlands 33% to 67% of the time. Obligate wetland plants are those found in wetlands greater than 99% of the time The vegetative communities along the Fenno Creek tributary are comprised of a mixed forest of deciduous and coniferous trees with some areas possessing an emergent or open water component. Within the mixed forest are included Douglas fir, big-leaf maple, willow species, red alder and Western red cedar. The understory of shrubs, small trees, and forbs varied depending upon the condition of the hydrology and the extent of the human disturbances. Vegetation found at the individual data points is recorded on the data sheets (Appendix A) and a species list for the project area is in Table 2. In section 1 (Figure 2) the wetland vegetation exists along a narrow stream approximately eight feet wide from the outflow of the culvert under McDonald Street and then becomes an emergent marsh area extending to the first fenceline crossing the stream. In this area, Himalayan blackberry and horsetail have grown from the edges of the drainage basin into the wetland area Hydrophytic vegetation, however, is still Strongly presept within the saturation zone bordering the stream, These species include slough sedge, willow species, skunk cabbage, wood fern, and, along the edge of the drainage, Western red cedar, The tree canopy along the edge of the drainage basin is moderately dense and the understory and shrub layer both in the wetland corridor and in the upland areas is dense, Further east down the drainage in Section 2 (Figure 3), the wetland vegetation continues to be found, but activities by the property owners there have significantly modified the conditions of the hydrological regime and the condition of the native species. In all bUt one area along the stteam, the stream itself has either been chartheliZed along the edge of lawns or diked to form small ponds, The native vegetation along the channelized sections tends to be limited in coverage and diversity, pical1y these areas contain creeping buttercup, willow species, wood fern, slough sedge, and Western red cedar within the wetland corridor, Along the banks of the stream, Himalayan blackberry, red alder, big-leaf maple, and cultivated grasses (fescues and rye species) were present depending upon the proxiinitY to the lawns and the disturbances, Along one section of the streain, the natural state of the stream corridor has remained relatively undisturbed. The structure and diversity of this mea reflects this Creeping bUttercup, wood fern, wood violet, strawberry, willow, blackberry, vine Maple, Red elderberry comprise the forb a hd Understory layers and red alder, big-leafed 47iS/vvetiatid.rep 099122 8 maple, Western red cedar, Rocky Mountain maple, e:. ar comprise the upper Canopy layer. The diked pond areas tend to support a good diversity of plant: species as well, where the emergent community is contained within the mixed forest community. Emergent species such as slough sedge, bulrush, and spreading rush are found in the more saturated soils and wood violet, waterleaff curly dock, morning glory, wood fern, himalayan blackberry, English ivy, and willow form the vegetative community lining the stream and ponds. The tree layer contains the same deciduous and coniferous species found previously.

MCDONALD SANITARY SEWERLINE TRUNK - WETLAND DELINEATION REPORT OTAK EVALUATION As a functioning biological system, wetlands can serve an ecosystem in a number of capacities. Wetlands function as habitat for wildlife, as a storage place for floodwaters, or they can function to purify the water that moves through them. The level at which a wetland functions is termed its value or functional value. It is this value that the regulations intend to protect in the `no net loss' rules. The wetland areas on this site were evaluated based on the WET II evaluation method. This method identifies 11 wetland functions (see Table 1) and provides the parameters to determine if these functions for a particular wetland area have a high, medium, or low value. Section 1 and 2: These sections are moderate to moderate -high. They are less disturbed in general than the assessed wetlands east of Hall Boulevard. Food chain support and wildlife habitat are both moderate to high. These functions remain high due to the presence of essentially continuous entire . d structure both vertically horizontally. along the sty ear�l course providing a goo to the mixed y lly. The positioning of the emergent area directly adjacent forest community provide higher diversity as a food source and greater habitat availability. Shoreline protection remains moderate and floodwater storage is ty p moderate. The resent i presence of lawn areas directly along the bank of the stream. in these sections lower the ability of the wetland to absorb greater stream flow and don't contribute as much to the protection of the banks from erosion: The presence of the pond areas, however, adds value to the floodwater storage function. The groundwater out this t.. . g i . p ... condition of the stream increases type of drainage basin. The semi-permanent recharge discharge equal in th ar and daschar e e ual ses the p ' permeability i limit the amount of rechare function. The the slow ermeabtl� of the soils here discharge g periodic ponds along the drainage tend to increase the extent of the recharge and serves to limit the discharge. Functions contributing uttn to water quality t n the drat nage range from moderate to moderate -hig h due to the high density of the forb and shrub vegetative layers. Again; the presence of lawn directly in the saturation . . to lower the water quality from levels found in emergent ar as as well as c eland tends the amount of , . , � , trib�ztes to q y g can f nutrients and sediment which result from fertilization and ground disturbances on the lots along the stream. Section 3 and 4: lower quality on xthe average compared to the These sections are moderate and slightly to ���� �� � �ualit "° �� other two sections. Also the wetlands within the proposed trunkline are smaller in acreage i tends to lower value, h t support a nd Wildlife habitat are moderate-high infu � on due to taecontinuo g chain in tree and shrub layer between the open meadow along Hall Boulevard and the forested corridor of 1Fanno Creek. Structure and habitat diversity contribute to both functions. Functions describing the streard course and the banks are difficult to assess within the easement because the proposed trunkline crosses the Fanno Creek tributary and Fanno Creek and 4 t8lvvntitintliip 0993,22 10 OTAK these functions are valuable only when an entire length of stream bank or stream is assessed. There is a presence of vegetative structure contributing to the integrity of the bank (See data sheet 13) The groundwater discharge is moderate -high due to the intermittently exposed /permanent condition of Fanno Creek and the lack of any significant areas where ponding can develop and contribute to the groundwater recharge. The remaining functions are low to moderate either due to the absence of significant amounts of emergent vegetation and the high degree of bank erosion on this portion of Fanno Creek. In these areas, the crossing must not impact the present condition of the stream b anQ ld which specifically can be measured by the vegetation present, because the impacts likely effect areas downstream in Fanno Creek,The minimal impact acreage results in lower mitigation requirement and if the construction is conducted appropriately the impacts to the drainage system will also be minimal. 47 isiwe.ininctrep 0993;22 • TABLE 1.

The riparian corridor is associated with a tributary of Fanno Creek flowing east from a culvert under McDonald Street to Hall Boulevard. The tributary includes natural riparian areas as well as channelized drainage and diked pond areas. The stream flows under Hall Boulevard and continues east to Fanno Creek. The site was evaluated for current wildlife habitat conditions and for potential impacts associated with the proposed project. As planned, the project is expected to have minor effects upon wildlife populations in the riparian area Opportunities for minimization of impacts exist and have been identified in this report. Similarly, recommendations regarding the wetland mitigation landscaping plans can also be found in Appendix B. . p organized complement the Wetland Delineation Report prepared for this site b report t eras or anized to com lenient th .. y OTAK in September of 1993. The stream has been divided into four sections for easy reference. a o� The stream sections and data points used are identical to those used in the p `� y This wildlife habitat assessment was performed following guidelines found in the Habitat Evaluation Procedure developed by the Portland Audobon Society, the Oregon Departrient of Fish and Wildlife, U.S. Fish and wildlife Service, U.S. EPA, and the Wetlands Conservancy. Additional protocol development support was obi ,tained from the U.S. EPA's Stream Walk programs.

Where possible, the general habitat types have been discussed in relationship to the wetland value data previously collected (Data Forms, Appendix A). Section 1 This section, which contains the highest quality wildlife habitat of the project area, extends east from McDonald Street to the private sports court area located downstream (Figure 2). The western portion of this section contains a narrow stream which emerges from a culvert passing under McDonald Street. The stream opens into an emergent wetland, filled with reed canarygrass and Himalayan blackberry, and is surrounded by a mixed forest with a diverse understory. The proximity of this forest to the emergent wetland enhances the value of this site, as does the presence of numerous standing dead trees (snags). The habitat diversity in this area is demonstrated by the concentration of numerous bird species. The dense forest canopy and the understory shrub layer provide good structure and diversity) resulting in excellent habitat values, The forb layer, mostly intact at the time of this visit, contributes to the high habitat and forage values. At the eastern edge of the meadow, the stream becomes confined to its channel again as it passes through a light forest into a residential area The homes located on the north side of the creek have impacted habitat value, The stream has been channelized in this area and several small dikes have created ponds adjacent to residential backyards, As the creek moves east toward the sports court, dominant hydrophytic vegetation (skunk cabbage) is replaced by lawn grasses, Bare soil and a barking dog also datract from habitat value in this area. However, the southern side of the creek remains a mixed deciduous forest, whose presence helps to preserve some of the habitat values in this area, This forest provides linkage between the high qua* habitat upstream and the moderately high quality area downstream, The understory and forb layers in this forest are minimal, Section 2 The stream is channelited in this area with bare banks and minimal vegetation present on the western portion of the site (Figure 3), The first of two ponds lacks adjacent vegetaiion and is low in habitat value, Another pond area just downstream, offers more significant opportunities for wildlife, The banks of this pond are well protected by hydrophytic vegetation and the area demonstrates high structure and diversity values for amphibians, birds, and small mammals, Water quality in this pond is moderate, with fairly high turbidity levels, The pond substrate is composed primarily of silt and organic material, Terrestrial vegetation in this area is diverse, including bamboo, cattails, sedges, mixed deciduott8 tree Species, and several significant snags, PA4716\11ABilttP 494,it• 3 • [Page Too Large for OCR Processing] [Page Too Large for OCR Processing] MCDONALD STREET SANITARY SEWERLINE TRUNK - HABITAT ASSESSMENT OTAK oetstett leaving the pond, the stream again resumes its eastward course, flowing through another heavily vegetated forest. This forest contains mixed deciduous and coniferous species and the shrub layer ranges from intact to absent, Several large western red cedars exist in this area Wildlife cover, nesting, and escape values are moderate to high here, and the presence of food and a consistent water supply further add to the value of this portion of the riparian corridor. Upon emerging from this forested area, the stream flows into a large pond with rip- rapped banks. The pond is surrounded by mowed lawn grasses and has the feel and appearance of a back -yard water feature. The proximity of this feature to residences makes it unlikely supports exception of ducks. The pond has a silty substrate Tr p dominated it ated b decaying n organic material and the water quality is moderate to poor. domrn y y g g Vegetative diversity is low, food values are low to moderate, and the pond is exposed and lacks significant cover.

WILDLIFE Numerous species of birds were observed using the project area for habitat, including; robins, jays, wrens, chickadees, finches, sparrows, ducks, and a red tail hawk (Table 1). Evidence also exists to indicate that woodpeckers frequent the project area Bird activity is particularly heavy in the western portion of the site Species not visually confirmed on site, but whose presence are suspected due to indicators include: frogs, noks, snakes, field mice, raccoons, possums and other small mammals, The indicators include ideal habitat conditions, burrows, nests, runs and evidence of serrated and chewed vegetation, In addition, fish species known to be present in Fanno Creek include: cutthroat trout, crappie, red-side shiners, bluegill, carp, dace, sculpin, three-spine sticklebacks (Tualatin Fish and Water Quality Report, DEQ 1987). SHORT TERM IMPACTS/MITIGATION OPPORTUNITIES Removal of Vegetation Removal and damage of vegetation during construction is an unavoidable impact associated with this project. However, many of the points located along the proposed alignment are dominated by invasive vegetative species. Removal of these species is expected to have a low to moderate impact upon habitat values, These impacts can be mitigated for by replacement vegetation that is higher in wildlife forage, cover, and habitat value. An effort to avoid removal of snags is encouraged. Water Quality Short term impacts to wEiter quality are possible Et a result of sewer line installation in the riparian corridor, To minimize potential sediment loading of the ponds and streatn, USA is encouraged to complete the construction during the dry weather season. In addition, filter fabric or some other sediment barrier should be placed between construction work and the water body, In area where work may occur directly in the stream channel, downstream silt barriers should be in place to prevent excessive downstream silt and debris migration. Guidance regarding these issties can be obtained from DSL and ODF&W, An additional effort should be made to revegetate disturbed soils as quickly as possifile following construction, Exposed sol create the potential for erosion and sediment loading during rain storms and should be stabilized immediately after constructioik, P 404,0 9 at '4;■ • •1 4 ..- 44 , hl k tit r1 . . ✓.,«∎ ∎∎ ty SCIENTIFIC NAME Aix sponsa Anal platyrhynchos Aphelocoma coerulescens Buteo jarnaisensis Carpodacus mexicanus Junco hyemalis Parun atricapillus Passerella iliaca Pip Pi ilo erythrophthalmus Regulus calendula COMMON NAME Wood Duck Mallard Scrub Jay House Finch Oregon Junco Black- capped Chickadee Fox Sparrow Rufous -sided Towhee Ruby - crowned Kinglet Winter Wren American Robin 1 /STREET SEWERLINE TRUNK .

Impacts resulting from installation of the sewer line can be effectively mitigated for and minimized through cautious planning. The impacts associated with long term maintenance and sewer line repair are not expected to pose a threat to wildlife or habitat values, provided that heavy equipment is kept out of the riparian area. However, long term impacts would be anticipated if an access road or trail system were developed in the riparian corridor, Habitat values along this site are somewhat fragmented p y i . ` could further add to this and. placement of such a structure without habitat mitigation, P y, in human active levels associated with the fragmentation. �' Similarly, physical habitat disturbances would detract from the current wildlife improved access an y habitat value.

The western lot line of 1500 is not drawn in on profile. This produced much confusion for property owner Nancy Young. Ms. Young also spent much time with Greg Barry and Terry discussing moving alignment south, closer to her property. After much discussion, we agreed that we could move it line south by moving manhole 16. Sue Vincent is concerned about a tree that was planted at the birth of her son. Our plans avoid it, but we should keep a close eye on it. Told her we would note it's location in easement negotiation. Questions: What effect will trench have on earthen dame near Hall Blvd? Contractor Will be below it and should not impact it at all. Has there been a cost analysis of this project versus upgrading pump station?
