Senior P1anner a�vised that the Transportation Advisory Comnittee was ir�yelved in th� drafting of �he map, and they wi11 review it again before it is pre�ented to the City Council on April 23� He spoke abou�t input received from NPOs, stating that NPO #`s and #7 were opposed to th� Murray �oulevard alignment, suggesting that the alignment of the roads shou�d, at the minimum, be d�signated as a study area from Scholls Ferry ° �oad to 121st Avenue. He advised NP0 #4 and #1 will have the opportunity to review the map on April 10, and their recommec�dations wi11 be forwarded to City Coun,cil.

He said NPO #�3, #7, and CPO #4 are opposed tn the Murray Road extens�on because the result would be an increased traffic fiaw c�ming from Beaverton into Tigard. As an alternative solution, they proposed directing traffic from Beaverton bound for Highway 99 to use Beef Bend Road, and avoid Bull Mountain neighborhood. o There was further discussion after wh7Ch Comnissi�ners and Senior Planner recflrtimended that Mr. Gro§s speak to the City Council about their co�rcerns. � � PUBLIC HE1lRING CLOSED '� , �, ,; o Corrmissioner Castil� s oE�e about the im urtance oF s -- � p� p p�ovi di r� �u�r• gbod traffic flow be�ween Scholls Ferry Road and 99W.

' WATER The Tigard area is served by the Ti�ard and Metzger Water Distric•t's which are �.wo independent wAter service districts. The two di.stricts, respectively, serve 80 and 2.0 p�r��ent' of Tigard area custo�ners. Tigard Water Distric�. ser✓es the area generally sou�thwest of the Highway 217, while Metzger Water District serves the area northeas� af the highway. This is illustrated by Figure 1. The City of Tigard•Comprehensive Plan states in Policy 7.3.1 that: "The City of �Tigard shall caordinate with the Tigard Wat�r District and the Metzger water Distriat to provide a high standard of water service to meet futwre d�tnands at a11 times." Tictard Water District The Tigard Water District is nota supplied with water purchased from the City of Lake Oswego, the City of Portland, and from district-owned wells on Bull Mt. and Littl� Bull Mt. During the year-ago period from June 1989, Lake Oswego provided 93� of the ISistrict's needs, Portland provided 4�, and District welis, 3�. An 800-scale map showing the eomplete Iocation of all district facilities entitled � "Map of Tigard Water District and V'icinity" is incorporated into this report by refer�nce. The City of Lake Oswego sells surplus water to the District. Lake Oswegc's supply capacity is naw at fu11 use, and it is c�nsidering a plan to make major additaons to its water system. One alternative includes facilities to fully � supply the Districti until the end of the City's p3anning period, which is 2012. Portland is now relied upon to make up the balance between need and the � availability af Cit,y af Lake Oswego water and well water. The District has not experien�ced difficul.ty in obtaining needed quantities from Portland. District � wells are used in the warm mont2is.

DetaiLed information on futuze water supply alternativ�s is contained in a 1990 ,;`. reporti. prepared. for the Tigard' Water District by Economie and Engineering : ' Serv�ices. The report is incorporated by r�fer�nce into this document. The findings ar�d conclusions of the report are attached as Appendix �'A" . '. The water sup�ly needs within the present boundaries of the District have been � forecas� to de��rm�.ne cor�struction requirements and aost of additions to present ' � supply facilities. These costs axe compared to the cost of developing new supply faaili-ties. The p].an�ing period extends to �he year 2010. �`hese forecasts are ba�ed on current C'ity of Tigard and Washington County land use plans and METRO i populatio�. projQ�tions. Tk�e four sup�a�.y alternat�.ves identified by the Econamic and Engineering Services :�- ; Report :are �ummarized in tihe followings Alternative 1: ��ansion of the Lake Osweao Source ' Lake Oswega obtains untrea�ed water from the Clackamas River near Gladstone. The ;; ci�.y's water x�.ghts at tl�at loaation are for 32.3 mgd. It i� possibie that State of Oregon min�mtam �l:ow reqwirements could pzevent the city from using an ,; addit�.onal water rights pezanit to obtain an extra 5.8 mgd. 5 �� Treated water reaches �he 4.0 mg Waluga Reservoir via the distribution system fed '!' by hi.gh service pumps and transmiasion line. This reservoir's. overflow is at �� elevaCion 320. 'She Tigard Wa�er Distric� owns 24 and 16 inch trunk Iines whicka extend frem the reservoir on Bqnita Road to Intierstate S, whexe flow is metered. , s`�; I-5 is crossed with a 24 inch line that branches with a r6-inch line up to the �on�ta Pump Station. The pump station pumps water into th� District's '410" zone whicii serves tlze majority of the district's custc+mers. The Bbnita station pumping capacit�y is about 7.9 mgd. The system cc�nnects into the distri.bution s�rst�m at th� railroad tracks. The 24 and 16 inch lines continue, except for � •�< aliout 350' feet of 12 in�h 3ine in place of 16-inch w�st of the tracks, along Bonita lt�acl to Iial1, northward on Hs11: to IMCDonald, and for about 600 feet nn MCDanald, Tk�es.e facilities are shown in the Map of Tigard Water District incorparated by refe�ence. The La]ce Ostvego Wa�er Master Plan recommends a 16.9 mgd expansion of the existi,ng �'� water tr�atment plant wa.thou� regard to Tigard's needs. A second•option under r ` cons�dexa.tion is upgrading of the Lake Os�ego system to meet Tigard's needs until '?� the year 2012. This later alt�rnative includes: ; ,,� - New r�w watex and £inished water transmission lines. - New raw water intakes and pum�s. � - New finished water pumps. 4 �- Expansian of existing water treatment plant to 23.2 mgd capacity. - Construction of a 5 mgd water treatment plant to treat Willamette `'' River wrat�r. Also, In order to upgrade the Aistrict's own pumping and transmission pipelines �' to �onwey pe�k flow to the "410" zone. the gollowing additional projects will be needed: � `i - A second pumping statinn nex� to the existir�g station on Banita Rd, This ''; station needs to have a 9 mgd capacity. i -3- :.>,,� 1� ;� „ �� ,'; �f� . . ... - - � . . . . . . . ^t...�.._.��_..��,_.�.._._...�.�....�v.t.�_......_,,,.........�_�._�_. . .. , . , . . _:�. �.,.�y..,...,�. �... __.....�. ......,.�_�.�__.._ ...,�:..,. .�,... �....._� _,..__�-,___ 3��.��.�_:�:.�: :; �_ � - Esctension of the 24 inch line on McDonald across S.W.

Present average use by i approxima�tely 700,000 customers amounts to about 55� of capaci�y. It is assumed that Portland could expand its Bull Run capacity for many decades before water availability becomes an issue. The Tigard Water distri.ct's distributian system ties to the Portland system at Bradley Corner at the intersection of Hall Blvd. and SW Greenburg Rd. through a 24 inch line connected to the Burlingame Stan.dpipes. The Tigard w�ter District owns a 16 inch transmission line beginning at a meter located along Greenburg Rd. across State FIighway 217 to Ash Creek. In order meet projeated 1995 needs, the following improvements from Bradley C�rner �o Greenburg Rd, at As,h Cre�k have been identified. - - Installation of a 24-inah line parallel with the existing 16-inch line from Bradley Corner to kiighw.ay 217 and installation of a new pressure xegulating vault. ,� - Replac�ment of the exis�ing 16-inch line beneath Highway 217 with a 24-inch l:ine. ` - Instiallation of another 24-inch line parallel with the exis�ing 16-inch ' :' line from Highway 217 ta Ash Creek. - Development of a second tie to the Portland water system at Haines Raad tvill require installatican of a pressure reducing vault o� a 12 inch line s near Baylor Reservoirs, and constructxon nf a 12 inch line crossing Interstate 5 in this location. Costs Eor increasing the capacity from Bradley Gorner ta the Dis�rict's 24 inch main on Greenburg at Ash Creek and for connecting to the Partland system at Haines Road are estimated at $667,OOQ. In about 1g95, about $5,000,000 will be :: needed for a new transmission system to Bradley Corner to meet the District's �' forecasted peak demands oF year 2010. Thus, the total, assuming the Tigard Water District pays all capital costs for incrpased supply from Portland is $5,66'7,000 for construction. Alterna�ive 3: Joinina th� Joxnt Water CAmmission (JWC) `r,: A third supply option under consideration involvLs joining the Joint Water Commissian composed of Hillsbora, Forest Grove, and Beaverton. The technical report included in the appendix describes in detail the facilities associated with devel.oping a supply from JWC. In outline, these include a 14 mgd raw water intake, a 14 mgd treatment plant, a 20 mg water tank, and various new pipelinES. The total capital costs associated with these improvements is estimated at $37,860,000 and do�s not include any value that the JWC may set on the £acilities now in place. Alternative 4: Acquirina Water �rom the Willamette River at Wilsonville `+ i A fourth supply option is the Willamette River at Wilsonville.

The total capital costs eatimate for this alternati�e is � $29,690,000. t ; In o�der to evaluate the relativE cast of the various water supply alternatives, '� a levelized cost analysis was undertaken. A levelizerl cost analysis determines ' the cost per 1:00 cubic Eeet of water assuming that the same rate would be paid 'i over the study period. This analysis sk�owed the two water supyal5j options that �i appear the most economically viable to the District over the twerity year planning , peri:od to 2010 �re the City of Lake Oswego and the City of Portland options. At ,� present, the da:strict is in the process of choosing one water supply alternative. c j; Bu11 Mountain Area Glater Facilities: k ... ... _ _. . . .. . . .. ; The Tigard Water District serves about 1,600 persons in the developing Bull ; Mountain area. ; j The Bul� Mountain area af the Tigard Water District includes some 2,800 acres oE ; residentYal and agricultural ].�nd lying between elevations 200 to 700. Of this, about 2,140 acres ar�e zoned for residential use and the balane� of 640 acres lies ' beyond th� Tigard Urban Growth Boun,dary, but within the Distric.t's planning area. ' At present, the current water supply i� adequate to meet existing demand. The Bull Mount�in water distribution system and xeservoir site are shown on the "Map of Tigar-d Water Distriet and Vicinity" and a].so in Appendix "A". The District's plan for storage and transmission within the Bull Mt. area envisi.ons the development of a water system from the summit downwards through new residential subdivisians ta reservoirs located at intermediate levels. In accordance wa.th a master plan developed for this area in '1986 by Gilbert Meigs, Consulting Engineer, a number of new facilities have been constructed and a reservos.r site acquired to serve the developing narth and northwest sides of the mountain. The fxndings and canclusians of this report are discussed and upciated in the previously referenced "Wat+er Swpply & 4�later Distzibution for Tigasd Wate� Da.str.ict" report. As shown an the master plan, two additional reservoirs serving the south side of the mountain ar�e recommended for eventual construction. one 16 ir�ch line and two 12 9.nch lihes al�a are needed to complete the installation of major Eacilities. The location of all facilities proposed fnr the Bull Mountain Area are based on a three phase schedule recommended by the "Water Supply & Water Distribution for Tigard Water Distriet" repor�. The phases extend from 1991 to 2005 and beyond and tatal about $5,000,000. Metzqer Water Distr.ict The Metzger Water District serves agproximately 20� of �he pnpulation located inside the City of Tigard. The City of Portlanci's Bull Run Reservoir is the source of one hundred percea�t of the district's water supplies. The district has a contract witih the City af Portland for supplies th�ough 2005. The storage capacity of the distric�'s resertroir is 8.5 million gallons. The distribution syst�m is gravity feed and consi�ts of approximately 80 miles of cast iron and ductile piping, ranging in size from 98 inches to two inchea A portion of this system i.s loeated within Tigard.

The plan, completed in 1991, shows how �anitary sewer service wi11 be provided thraughaut the Tigard Urban Planning Area. The plan supplements the current U,S.A. Maste� Plan. It divides the planning area into 68 service areas. This provides suEficient detaal to show improvements required �o serve each individual pa:rcel �rithin the s�udy area. According to this plan, the condition of existing facilities is generally rated in good to fair condition. An up to date index of, "Extensions Required to Provide Service to Unsewered Areas, " is attar,hed as an appendix to the Sanitary Sewer Facility Plan. Also included as a map exhzbit in the faaility plan is a summary of areas tha�t are currently served and not served l�y sanitary sewer. This map also indicates lines that require additional eapaci�y. These lines will be either replaced or para11e1 lines will be � • -- ins�aTled. �! ^� With two exceptions, the Sanitary Sewer Facility Plan indicates that the planning r` area can be fully served through local improvemen� distriets or by rec�uiring �levele.pers to ins�all facilities. The two locations which will recguire the expenditure of public funds are indicate�l on the sanitary sewer plan map exhibit in Appendix "B". They include: - S.W. McDonald Street 5anitary Sewer: A sewer in S.W. McDonald Street will be installed as part of a street capital improvement projeat. The estimated cost of this project was $165,000 and will be completed in 1991. �` - Industrial Sewer Area: The line serving the area. baunded by Pacific Highway, Interstate 5 and Highway 217 has been identified as having - inadequate capacity. Furthermore, a portion of the line is at an adverse gr�de. Only a �ortion of the line belaw SoW. Hunziker was considered for improvement. If demands significantly exceed those expected, improvements above S.W. Hunziker Street will be cQnsidered. The estim�ced cost of this pro�ect is $52,Q00. xhe Sanitarv Sewer Facilitv Plan makes €our recommendations. Fir�t, sanitary sewers should be extended to undeveloped areas as development occurs, with the developer building the sewers. Second, the City should continue its policy of facilitating agreements among pxoperty owners in r3eveloped but unsewered areas ta fund needed sewers. Third, construction of the industriai area sanitary sewer capital improvement project sYAOUld be completed during tha summer of 1991. Benefitting property owners will likely be assessed for the S.W. McDonald St. sanitary sewer praject. Fourth, the need for improvements to provide increased capacity to portions of 17 U.S.A. and City awnecl lines identified in the report should be determined by a flow monitoring program. U.S.A, should be notified of the need F�� in�pr�vetnents tha� are tih� responsiba.lity of the �,gency. ,:; -7- ; �1, ' h�i i �.: 1 r �� h '1''�-iry ^c _ -c "r-'r-.�: r �. ,� F ^-+ � - - r. r " . . `taa i . ..-:. . , ._,3-�� .„-i.. . .,�. . . �4.. ...,.

K STORM SEWER r ; The regxonal stormwater service pravicier throughout the urbanized area of Washington County is the Unified Sewerage Agency. In response to new water quality sGandards for the Tualatin River established by the Oregon State Department af Environmental Quality in 1989, U.S.A. has develo�ped a stormwater management program fQr the preservation of water quality. The plan addresses ` nan-point source pollution, rainfall-related erosion and sedimentation, and flood control. Furthermore, the City of Tigard has enicered into an agreement wa.th II.S.A. to ; address surface water management functions. This agreement is attached as Appendix "C" . The City is resp4nsible for all storm and surface water facilities within the corpnrate limits of the City except for thase specifically identified on the attached Figure 2, "U.S.A. Mair►tenance Areas " . The "U.S.A. Maintenance Areas" include the floodplain and wetlands associated with the drainage courses. � Th�y are shadpd in blue on Figure 2. The City of Tigard Comprehensive Plan policies provide direction as to how storm water manageanent wil� be acidrassed. ; Policies 7.2.1 and 7.2.2 respectively state: ' "The City shall require as a pre-condition of development approval to development that: a) A site develapment study be submitted for development in areas subject to poor drainage, ground instability or flooding which shows that tha d��relopment is safe and will not create adverse off-site impacts: z b) Natural drainage ways shall be maintained unless submitted studies show that al'cernative drainage solutions aarx solve an-site drainage problems ;i . • � and will assure no adverse offsite impacts; i c) A11 drain�.ge can be handled on-site or there is an alternative solution ; which will not increase the offsite impa�ct; • d) The 100-year flo�dplain as established b y the 1981 Flood Insurance Skudy conducted by the U.S. Army Corps of Engineers be prntected; ancl ;� e) Erosion control techniques be included as part of the site development s plan." � "ThE City sha11: ` a) Include it its capital imgrovements program, plans for s�lvin� drainage prablems in the existing developed areas; i b) Recognize anci assume its responsibility for operating, planning and �egulating wastewater systems as designated in the MSD Wastewatex Treatmen't Management "208" Plan; and �; c) Apply a1Z applic�ble federal and state laws and regulations wzth respect ' to wastewater. � The City retains ownership of and maintenance responsibility for all public park facilities and public pathways within the "U.S.A.

Citv of Tiaard Master Drainage _Plan The Current city-wide master .drainage plan for the City was prepared by CH2M Hill in 1981. This pla.n incorpox�ates procedures and standards regarding subdivision and storm�water detention along with recommQnded flood plan managem�nt measures. The study also contained a series of recomm�ndations and solutions t�he study increase the flow efficiency of the Fanno Creek floodway. Fc�r example, stated that numerous bridges, i.e. the Tigard Street and North Dakota Street bridges, are curzently below flood elevation and these bridges substantially decrease the flowr of water along Fanno Creek. •It is suggested in the study that raisi.ng the bridge deck would alleviate much of the reatricted water flow along Fanno Creek. Tt further outlines the requirements and cost for development of an effective draina�e management system. In the ten years since this study was compl�ted many of these recommended improvements have been completed. The "Master DrainaQe Plan -- Citv of Tiaard, CH2M-Hill is incarporated by referer�ce into this r�pox°�• The report's antroductory chapter outlining its purpose is attaahed as Appendix "E"• Despite the "Master Drainage Plan's" usefulness, many of i.ts recommendations h�ve I been superseded by U.S.A.

Summer Creek Recommended Plan Management of Summer Creek flooding is recommended for the entire length of the stream included in the study area. 121st Ave. Crossing. The 121st Ave culvert should be replaced by a bridge crassing �o eliminate upstream flaoding along Summercrest Dr. If deposition is found to be occurring downstream o£ the existing culvert, a major channel i: improvement o€ 1,800 feet is recommended. Tualatin River Recommended Plan: Management of flooding along the Tualatin River is recommended for the enti.re reach of tlie river that forms Tigard's sou�hern border. Cost estimates for the recomm�nded drainage improvements are 3ncludec3 .in the master plarao biowever, i�a anaaxy cases these cost estimates are not applicable because of the time which has elapsed since they were fixst developed and the changes that have occurred in storm water and drainageway management practices. � ;, The Unified 6ewerage Agency currently collects a storm water management fee from the owners of developed parcels to be used for major storm drainage improvement . projects and certain maxntenanr.e activities.

Plw.ns are currently underway for th� constructa.on of a park and ride station located at as y�t u�determined site on Pacifia Highway in Tigard. The size, design, and parks.ng capacity ag the facility also have not been determined as yet. A summary description of the proposed Tigard Park and Ride is attached as Appendix "r^". The eventual extension of a light rail line is in the conceptual stage. The City of Portland has engaged a consultant undertakP preliminary planning or systems level ana:lysis af poten�ial light rail alignments in the Barbur Blvd. Corridar between dorantown Portland and �'igard. This study will alsu examine potential light rai.l serviee to Wasl�ington Square. Ti.ctard Area Gomprehensive Pedestrian-Bicvcle Pathwav Plan The Tigard Area Comprehensive Pedestrian-Bicycle Pathway Plan was first prepared in 1974. It contained a recommended phasing of improvement projects for a City initiated pedestrian-�bicycle pathway program. The Pedestrian-Bicycle Plan was updated in 1985 and is included as Figure 6. Future updates of the Pedestrian- Bicycle Plan will be incorporated into the Public Faci7.ity Plan as they are developed. The City of Tigard Com�rehensive Plan provides policy direction for bicycle and pec�estrian facilities. The plan states in policy 8.4.1; "The City shall located bicycle/pedestrian corridnrs in a manner which provides for pedestrian and bicycle users saf� �nd convenient movement in all parts of the city , by developing the pathway system shown on the adopted pedestri,an/bikeway plan. The pedestrian and bikeway plan is implemented incrementally along with major transportation improvements conducted by ODOT and the City of Tigard. In � addition, developers are reguiLed to provide for bicycle and p2destrian paths whe�, developing adjacent to a floodplain, city designated greenway, or wetland. Short Term Bicvcle/Pedestrian Path Proiects: In addition to bikeways to be constructed as part of street projects, the City � wi11 implement £ive major bikeway projects as part of the Tigard Tt►ree Park Levy which was passed by Tigard voters in 1589.

In response to thi� situation, and because La]ce Oswego now has a�eceived an engineering repart on expansion of its supply system that could , involve the District, th� �istnct retained Econo�ic and Engmeering Servaces, I Inc. (EES) to prepaze this study of future sources, including Lake Oswe$o and � three other alternattves. { Additionally, growth coatinues withui the Bull Mountain area, and the Di�trict I included a revievc►of facilities to provide water to and within tl�ai area. Finally, long term replacernents and reinforcements as well as �ain extensions f to s�rve new customers has continued in the "410" zone. The Di�tri�ct included a review of the mains and storage within this, the preponderant zone dvithin th� Distriet,to provide a tnore complete s�udy of all waterworles facilities. �� 2.

In the �iscal year 1988/89, t�e District bought 92.8% of its supply from � �;� Lake Qswego and 3.7% frarn the City of Portland, and pumped 3.5% from wells at Stations No. 1 and No,2. 2. Basic sources considered in this study and their exposure to raw water cont�xa�n�ts are: ;�r �� Expasure Level Clackamas River City�nf Iake Oswego Average Bull Run River City of Po�rtland ��t �` Upper Tualatin River Joint Water Commission Minor VV'illam�tte River _. Tigard,if developed Wc►rst ' Regulations being developed by the State and Federal authorities will - � :;►: most hkely add to the cost of all sources, but it is impractical t� attempt .,.. to quaaitify the cost impacts. "' 3. Y..ake Oswego sells surplus water, and in hot weather is unable to fuily `� supply the Distric�t. I..�:ke Oswego is eonsidering expansion Af its su ply {:� system on the Clackamas River to serve (1) only its own neecls or (2� its j needs and those of the Distric�t. The present and pr�pnsed �oint of ��•. deliv�� to the District is tlae 4.0 mg Waluga reservoir at elevat�on 320, " � " .�►hic��s 90 feet lovver than the Distnct's rseeivsng reservoirs.

District and Lake Oswego make major policy decisions. The �rst phase probably would extend from 1991 to 1994. Bearin.g this in mind, the schedule and total capital costs for a �rm supply from Lake Oswego � amount to: Year Total Capital Costs 1991 to 1994 $19,136,000 ' ' Between 1997 and 2004 2.296.000 'Y'otal $21,432,000 If the Distcict were to cornmit to a long-term supply based on Lake �Oswego's sources, then it should become a partner in managing and financing the supply system. -� 4. Portland's primary water source i�the Bull Run River, and it is backed-up by a groundwater supply for intermittent use. There is an adequate '°' supply at Bull Run, but the future nature and cost of disinfection, ' '�{ impoundment utilization and additionaZ transmission lines are not yet - defined by studies now in progress. The lDistrict is now under contract with Portland to purchase at least '''''' 3.6% of its Sales from a meter at Bradley Comer. This water is transmitted onward to the District through a pressure-controlled system ,: of p�pelines. �� Portland has advised EF,S that 6 to 8 mgd now are available at Bradley �"�` Corner. 'The residual pressure is adequate f�r gravity flow tc� the 10 mg '�` reservoir on Bull Mountain. Further, Portland states that there is a �� pntential 1 mgd aow available on tk�e east side of Highway I-5 at �-iaines ,;�i., Road and that 3 mgd will be there available in 1993. `:� Pc�rtland further states that a new transmission system will be needed to ',;�, meet the�istrict's forecasted peak demands of year�J10. EES estimates � + that this system will be needed in 19g5, althnugh storage utilization �� and/or conservation may postpone the need for a few yeazs. C.osts for increasing t�e capacity froan Bradley Corner to the DiStrict's 24- �.� inch anain on Greenburg Road at Ash Creek and for cQnnecting tc� Porilaa�d at �€ai�es R�ad are estimated at $66�,OOQ and would be scheduled for FY91. In about 1995, about$5,000,000 will be needed for a ``� new system to Bradl�ey Coraer.

The �� ' � capxtal cost of this�rst phase is estimated at$35,760,000,including cost of ;� storage at Trask River Dam.

Before any �� design �s undertalcen, a a�aw water quality testing program should be � �;; in , implemented. � �r � y,� �;� For thc District to draw on the Willamett� River as a source af drinking �� water,this study assumes an intake 13 miles upstreazn of highway I-5 and �� a 6,500 foot lime to a 14 mgd treatment lant west of Danimasch State k� e� � Hos�pital. The treatment process o pre-ozonatioa, coagulation, }'� sedimentation, filtaration and disinfection, would be supplemented with �� granulated activated carbon beds for synthetic organic removal.

INTRODUCTIOl�7 The goal of this study is to provide a plan for ensuring adequate sanitary s�wer service throughout the City when fully developed. This will require accomplishing the following objectives: Ensu.re that lines canstructed for new developments can be readily extended to serve other areas within the basin as development occurs; Provide a guide for �roviding= sewers to developed but unsewered areas within the study area; Identify portions of the future colleGtion system that should be considered for a capital improvement project; ; and De�er�eaine adequacy of each existing line to meet the demands from the area it sexves when fully devel�oped. The plan is for the area des'cribed on the City°s Comprehensive Plan Map - Land Use, as the t3rban Planning Area Agreement. Ia� 1970, the �ity entered into an �greemen� with the Unified Sewexage Agency of ' WashingCon C�unty that provided that the City would enforce �onstruction standards, rules and regulatians, and rates and charges governing th� use of and connection to the City's sanitary sewerage syst�m-e In turn, U..S�A. agreed to provid� trunk and . interceptar lines, as well .as t�eatment facilities. ]Cn 1985, the U.5.A. adopted the Master P1an Upd�te as its current plan. That plan, was an update of the Tualatin Basin Wat�r and Sewerage Master P1an prepared for Washington Caunty in 1969. The intent of this plan is to provide a supplement to the U.S.A. plan �� by dividing the planning area into 68 service areas rather than the 4 sub-basins of the U.S.A. plan that are wi�hin the Ci.ty's Planning Area Agreeanent, This will provide sufficient detail to show improvements required to serve each individual parcel within the study area. 2 . EXISTING FA�ILITIES � The condition of the existing facilities have been evaluated by� inspecting the pipe interiors with a video camera. Nearly the . entire system has been inspected as a result of a routine � - irispection program. Damaged or improperly canstructec� facilities wer� repaired as encountered resulting in a syst�m tha.t is �. generally rated in good to fair condition. City staff has pre�ared �: an index map of existing facilitie� from as-constructed drawings. Th� map is continuous�.y revised as as-constructed d�awings are received, � SANITARY SEVaER FACILITY PLAN PACE 1 r' / •:,,.._ . . _.,, , _.; ,.:. , ,,,, ._._..._. _,.,r---, _ - - , , ,� , � �� ...: .., . , ; ,',.` , ..:: < .', - - , ,. „ .._.� -�-„�;..,.�:,�.,, .�. . .�..._ ..:.:.-_�,�, =�..... :-,.:: -�. .�:.,�.,u:�_ ____.. ._.-.�_ w�;.:�,:_�� . _.:�.�,� �n se�...k..J.t.:^.... ........�_., ...._.�t ...., ...-. _.....,_., ......._......................,...+r.uaµ ^s._e�.sc_...�_�......... ......,„._........_....b...,....w.,....�w.t.......>.w.�we..,,.� ,. ..__.....�..�..m.._w.,........�......,�w..,..-................o....�...,., � . �f .Y .t � . wd :':. 3a SYSTEM EVALUATION' � �.'he system was evaluated by first d�termining the adequacy of the capacity of existing lines to me�t expect�ed demands. Next, the ' sewer extensions necessary to serve areas currently unsewered were detiermin�d. �: " 3.1 Capacitv oE �xistin Lines �? Tkie U.S.A, Ma;ster Plan included an evaluation of the capacity of the large� existing lines within the Gity. Impro�tr�ements were recoatunended to accommodate various extents of dev�lopment, short term improvements are required fnr existing - deve3opm�nt, long term improveanents for development expected '4" � : to oc�ur �iy 2U05, and improvements required for ultimate dewelopm�nt. Recommended improvements require that lines witZ� inadequate aapaci�t� b� either replaeed or provided �nrith a Par�1.1�1 �.ine as shown or� TABLE 1. 4 : r ° The location o� the improvement required fo� expected ,,,= increased demand are shown on Map 1 by projec� number. � i Antia�.�ating the need for these impravements aan be l�est accamplislied by znanitoring the rate of flow in the manhole ` imtnediatel� downstream of the propos�d improvement. By �a ? projecting the increased rate of flow, the time the proposed improvement will be r�quired can be de�eranined. Future deVelopment at less than expected intensit�es may eliminate the neecl for some of the proposed improv+ements. ;.';,; ;_; ;:;_� ;;;;;; ;;�,� .. ��:� \=s: `;i !,' ,;,� �z; ;', ,� , '<, � .a . ;z; r'� SANSTARY �EWER F`ACI.LTTY PLAN PAGE 2 � r� � t ' t' z4 !-�n �r 4 ; 1 �' f r ;4 :3 � ^-r , � ,... . ., �.. . .�� ',� . ,_,� ��. , ... , � .,'-�i7-,. �,� �� ,�� r._,<„ � ��_� .,1„ ,. ,1, _ _ _ — �.-� .. _�...._:.. . ._�.,.

' �'3 �� Chapter 1 INTRODUCTION " ::�•l Master dxainage planning involves a broad planning process . for uxban drainage and flood control that will assist the ::;:� City of Tigaxd in achieving its stated goals and policy objectives. Implementatian of the drainage plan should� reduce the public c�st for storm �ewers, channels, culverts, ' and bridges an3 lowe.r the costs for mainten�nce and rehabilita- . �';;� tion followingt floods. The. drainage p�an id�ntifies both �xis�ing and future drainage problems. The goal af the master plan is to eliminate those problems through a de£ined ;;:� implementation process. � '`''� The mast�r drainage plan prepares a course of action for ;r� implem�nta-�ion and maintenance of urban drainage works through correcti.�e and preventive measures. Corrective measures ';�� seek tci z��,tigate flood damage potential ��,hat has been cr�ated by the urban development encroaching on the natural flood ..`� plagns. Preventive measu�es are a�hi�v�ed through flood-plain mana�ement with the abjective of reducing both rainor and �ajor starms' damage potential before future development � can encroach on fihe flood plain. � Mastex drainage plan�ing for the urban drainage network is � based on the premise that two separate and functionally :'� distinct drainage systemns exist. The firs�t, or minor, system aceommodates the storm �unoff' exgected once every 2 to 10 years. It consi��s o£ property la.ns swales, stxeets and c�utters, starr� sew�rs, and sartaller ope� drainageways. It ';'� � provid�� convenience drai.nage, reduces street maintenance eosts, and directly aff�cts the orderliness of aa� urbanized . �rea. The second, ar major, system handles runoff from � th� JL00-year storm runoff event in ordex to prevent loss of life and major d�nage. Storm runoff� follaws the major drainage system rout� during a majoac storm, whether or not I� the rout� is planned or deeelopment is wisely situa��e� r�ya- tive �o t�±?± ��te_ T;�� -yea� stax�n is studied to ensure compatibilitp with state and Federal f].00d-plain manage- ment p�licies, although facilities may, in sorae cases, b� � designed for lesser events for economic reasons_ In these cases, the effect of the 100-year storm is considered when assessing th� impact of the impravements. � ---- - i aThxoughout this �eport, "existing conditions" refers to � the conditions in I979, whe� both ttle COE's and CH2M ` HILL's hydrological studies were conducted. "Future con- ditions" refers to projected condi�ions of development or 1 land use in tYie year 2a00. � t .� � ::j � 274A 1-I , � ' ' r r t - _ � . , .. . . , . . � � .. . _. , , ...�. ... .. .. .... _. - '_ __ - � �� 1 ^� The management strategies developed in this plan are for � open drainageways because they provide the basic out�.et --� for both minor and major stormwater in each drainage basin. If the open drainageways are nat preserved or improved, they will not be able to handle increased amounts of stoxm- water runof�', wh�ich can be expected as furt�ier urbanization � � takes place. The plannin.g effort in this study has concen- trated an the drainage system of Fanno Creek and its two major tributaries, Ash Creek and Summer Creek. However, 1 � many of the plan recommendations will be applicable to other 1 dra�.nage systems outside Fanno Creek. In addition, tYxe problems of flooding on the Tualatin River a.re identified. ._� Many demands are being made on the land and water resou�c�s in the �Tigard area. These demands are associated wit;h ef- forts to achieve a variety of objectives, such a� ecanom�.c ;°;� developraent, iocal and regional development, transportation, sa�cial well-�being, and environmental quality. Because land resources are limited, these objectives compete with one another. Thos� that concem the drainage system will be � reconciled thrQUgh a formal drainage planning stra�.egy that includes: s Identification of the c�mprehensive goa�.s and � policy objectives of the City of Tigard and its �, sur.�aunding urban �rowth area ,,, • H drolo ic si.mulation of drainage basins for a �� Y g range o�' drainage stratec�ies that r�flect existing and expected £uture conditions of development � e Del.ineation o� flood hazard areas • Identificat�on ar,� PtT4�;��;,Ll �i � range of drain- � ' a g e m a n a g e m e n t a l t e m at iv�s, includin g corrective � a�nd preventive measures ' • Recommendation of a proposed cou.rse of action :_� the City may follow to implement, legislate, and maintain the drainage system so it serves as a � functional system within the total development strategy for the City of Tigard Throughout the plaz�ning p�ocess there has been an attempt ,. • I Lo combine urban runoff managesnent with other urban systems � � " to enhance the overall urban setting. Many urban drainage systems can accommodate othez benefits besides ��hieving � the Dt�rnn�p �i stv�tnwater management. Sy�tems that are tnore functicsnal can be achieved economically by integratin� the urban systems. Some of �he secondary benefits realized thxoc�gh an. e££ecti.ve dr�i.nage progra�n include reduced stree� � construction and maintenance costs, an improved pubiic health � znvironment, lower costs for open space and park areas, and ~� development of othenaise undevelopable land. �-# I 274A 1-2 . � �., .,, � - .�,�,.__ � . _ . ., s, � � " � r t i � + 7 ' ,1 .,,�.,.�..�.�,.�.,,��,,._ �,.:�,;.�,:»,.�..0 . . . .r.�:,..r.:;u.,. . . .- _ . . ,....._..d.w...,...�,a..,�wwu.�.,�..,�...,rT,r,.4........�_._..._ �-4-.. `�-..J x �: ` � � � . . . � .. !c; �;�' . . . . , � . . � . � .. . . :� The master drainage planning process resul�.s in production '' o�' a recommended plan. for management o� �he open drainage- �� ,l ways_ , �he: pl�n'is a pxoduct of engineering and economic '�i studies of` the present ghysical env�ronment and af the ex�- ', p�c�ed, dev�lopment changes through the pl,anning period (the } 4 � � rie�xt 20 ye�a-rs)�. � � � ',{� �� > �� Thr.oughout; this planning process, input from municipal of- a:� fia�.aZ's has beeri solicited to ensure co�npati�ilit� af the �>. .� r�cciaunended strategi�s �ith the city of Tigard's goals and .

'a . � The proj�ct will. be constructed on land provided hy the Oregon ` L9epartment of Transporta�ion. Total UMTA�eligible project costs axe estimated at $335,000 for design and construction. A cost allocation plan wi�.l be sub- mitted at a later da�e. A cost breakdown is provided in �xhibit 1. II. PROJECT �ITSTI�'ICATIONf The Transit Develapment Plaxa Update adopted by the Tri-Me� Board ; of Directors in 1987 calls �or improvements to txansit s�rvice and facilities in the Tri-Met District, including con�tructi.�r� of a Tigard Pa�k and Ride. The Tiga�d Park and Ride is an i.mpar�ant part of Tri-Met's Plans to improve transit service in the 99W � Corridor. The Ti.gard Park �nd ride would provide an opportunity for current � and pc�tential transit patrons to acce�s the trunk line service in ; this corridor. Today, the lack af transit trunkline or feeder � service in the high growtYi areas north and sout� of 99W is � deterrea�� to transit usage. The exis�ing Park and ride facility � on Barbus Boulevard, approximately 3.2 miles nortlxeast of the '� site, is over capacity despite recent moda.fications to increase � the n�nber of spa�es. A significant amoun� og unauthoriz�d park � and ride activity currently occurs at a number of locations along _ �� the 99W trunklin� route. These existing ra�ders may be lost as y� unauthorized park aa�d ride �paces are los� to rerievelopment. �� Expanded park and ride capacity will all.ow for increased transit �� ridership and is expected to contribu�te to the ameliorati�n of . i� growing conges�ion levels �long Pacific Highway. The �roposed z� � facility is the outgrowth of a cooperative planning effort �� involving Tri-Met, the Oregon Departzuent of Transpoxtation, and f� a • the City of Tigard ta pravide eatp�nded �ark and ride capacity in ;� �"�r this corx�idor. � � � � �� . � �__•,�SYV".... _il . .w,L+r _ .::.. __ _ " ' - ��'e� �' • . � A ti C• �;_. - III. ENVIRONIrYENTAL DOCLTMENTA�ION � An �x�vironmenta� Assessment (EA) was coznpleted in December 1989. Tri-Met enlisted the coagerativn o€ o�her agencies and jurisdic- tions in the environm�ntal review. The findings of the EA aze that n� significant environmental impacts will result from the proj�ct. A Findinq of No Significant Impact is requeste+d �rcaaa DMTA far the prnject, N. PROJECT IMPLEMENTAT�ON PI�AN Final design of the Park and Ride� Iot is expected to cammence in � August - September of 1990 and extend through March of 1991. The � timinq of constructi�n will depend on acquisition of the site, which is expected between Ja�nuary and Septemk�er of 1991, depending _ on the avaal�bility of Federal Highway Adnairaistr�tion funds. Construction wi11 coa�ence as soon as possible after lanc� acc;uisition and wi�l take app�oxima�ely four months. Encuaiberm�r�� nd Disbursement Data ,°s; -- ' �S`. Estimated Estimated Fed. �'Y Otrs.
