It serves as a support document to the Tigard Comprehensive Plan and provides background information pertaining to public facil.ties which serve the City. Information pertaining to Tigard`s water, sanitary sewer, storm drainage and transportation systems is provided in the following report and support documents. These are the key physical facilities necessary to support urban development and are those for which specific documentation is required by the Public Facilities Plan Rule (OAR 660-11-000) . This report also references several public facility studies published between 1981 and 1991, Selected excerpts are attached as appendices. The entire documents are available at the City of Tigard City Hall, located at 13125 SW Hall Boulevard, Tigard, OR and are ,incorporated into this report by reference. PUBLIC FACILITIES PLANNING OAR 660-11-000 requires cities and counties to develop and adopt a public facility plan. Public facility plans are not detailed capital improvements pians but instead are more general facility plans that are intended to identify the significant facility improvements necessary to accommodate orderly development within urban growth boundaries. The following document examines the following major public facility systems within the Tigard urban growth area: { 1) Water System. Review of the water system includes the following: a) Sources of water. b) Treatment system. c) Storage system. d) Pumping system. e) Primary distribution system. 2) Sanitary sewer. Information pertaining to the sanitary sewer system includes the following: a) Treatment system. b) Primary collection system. 3) Storm Sewer: Review of the storm sewer system encompasses major storm drainage conveyances including major trunk lines, streams, ditches, pump stations and retention basins. 4) Transportation: The transportation portion of the public facility plan includes: a) Freeway system. { b) Arterial system. c) Significant, collector system. d) Bridge system (those on the federal bridge inventory) e) Mass transit facilities. f) Bicycle paths. _1- The following report or attached appendices and facility studies incorporated by reference include the following detailed information about each of the above facility categories: 1) Inventory and general assessment of the condition of existing public facility systems, including: a) Mapped location of the facility or service area. b) Facility capacity or size. c) General assessment of condition of the facility. 2) A list of significant future public facility projects and project descriptions, including: a) Rough cost estimates for each. b) Map or written description of each project's general location or service area. c) Policy statement or agreement identifying the provider of each System. d) Estimate,if possible, of when each facility will be needed. e) Discussion of existing funding mechanism and the ability of these and possible new mechanisms to fund the development of each public facility project. 3) Detailed facility maps and studies including engineering information. WATER The Tigard area is served by the Tigard and Metzger Water Districts which are two independent water service districts. The two districts, respectively, serve 80 and 20 per cent of Tigard area customers. Tgard Water District serves the area generally southwest of Highway 217, while Metzger Water District serves the area northeast of the highway. This is illustrated by Figure 1. The City ofTigardComprehensive Plan states in Policy 7.3.1 that: "The City of Tigard shall coordinate with the Tigard Water District and the Metzger water District to provide a high standard of water service to meet futuredemandsat all times." Tigard Water District The Tigard Water District is now supplied with water purchased from the City of Lake Oswego, the City of Portland, and from district-owned wells on Bull Mt. and Little Bull Mt. During the year-ago period ending June 1989, Lake Oswego provided 93% of the District's needs, Portland provided 4%, and District wells, 3%. An 800-scale map showing the complete location of all district facilities entitled "Map of Tigard Water District and Vicinity" is incorporated into this report by reference. The City cf Lake Oswego sells surplus water to the District. Lake Oswego's supply capacity is now at full use, and it is considering a plan to make major additions to its water system. One alternative includes facilities to fully supply the District until the end of the City's planning period, which is 2012. Portland is now relied upon to make up the balance between need and the availability of City of Lake Oswego water and well water. The District has not experienced difficulty in obtaining needed quantities from Portland. District wells are used in the warm months. The production costs associated with these is low relative to water purchases. Because these wells are in the Cooper -2- 1 ) LF CREEKtc!

Critical Ground Water Area designated by the State Water Resources Dept., future utilization will not significantly increase above the current level. Detailed information on future water supply alternatives is contained in a 1990 report prepared for the Tigard Water District by Economic and Engineering Services. The report is incorporated by reference into this document. The findings and conclusions of the report are attached as Appendix "A The water supply needs within the present boundaries of the District have been forecast to determine construction requirements and cost of additions to present supply facilities. These costs are compared to the cost of developing new supply facilities. The planning period extends to the year 2010. These forecasts are based on current City of Tigard and Washington County land use plans and METRO population projections. The four supply alternatives identified by the Economic and Engineering Services Report are summarized in the following: Alternative 1• Expansion of the Lake Oswego Source Lake Oswego obtains untreated water from the Clackamas River near Gladstone. The city's water rights at that location are for 32.3 mgd. It is possible that State of Oregon minimum flow requirements could prevent the city from using an additional water rights permit to obtain an extra 5.8 mgd. Treated water reaches the 4.0 mq Waluga Reservoir via the distribution system fed by high service pumps and transmission line. This reservoir's overflow is at elevation 320. The Tigard Water District owns 24 and 16 inch trunk lines which extend from the reservoir on Bonita Road to Interstate 5, where flow is metered. _ 2 inch .line that branches with a 16-inch line up to the I 5 is crossed with a 4 i " „ Bcnita Pump Station. The pump station pumps water into the District's 910 zone -which serves the majority of the district's customers. The Bonita station pumping capacity is about 7.9 mgd. The system connects into the distribution system at the railroad tracks. The 24 and 16 inch lines continue, except for about 350 feet of 12 inch Tine in place of 16-inch west of the tracks, along Bonita Road to Hall, northward on Hall to McDonald, and for about 600 feet on McDonald. These facilities are shown in the Map of Tigard Water District incorporated by reference. The Lake Oswego Water Master Plan recommends a_16.9 mgd expansion of`th,e,existing water treatment plant without regard to Tigard's needs. A second option under consideration is upgrading of the Lake Oswego system to m,iet Tigard's needs until- the year 2012. This later alternative includes: New raw water and finished water transmission lines. New raw water intakes and pumps. - New finished water pumps: Expansion of existing water treatment plant to 23.2 mgd capacity. - Construction of a 5 mgd water treatment plant to treat Willamette River water. Also, In order to upgrade the District's own pumping and transmission pipelines to convey peak flow to the "410" zone, the following additional projects will be ; needed: A second pumping station next to the existing station on Bonita Rd. This station needs to have a 9 mgd capacity. -3 - Extension of the 24 inch line on McDonald across S.W. Pacific Highway to j the 36 inch line on SW Gaarde. \ Total costs associated with these improvements would total - For the year 1991. . . . . . . .. . . . ...$19,136,000 - Between 1997 and 2004. . . . .. . . .... .2,296,000 Total $21,432,000 Alternative 2: Increase Capacity from the City of Portland (Bull Run) Sources Portland's primary supply is the Bull Run River. Present average use by approximately 700,000 customers amounts to about 558 of capacity. It is assumed that Portland could expand its Bull Run capacity for many decades before water availability becomes an issue. The Tigard Water district's distribution 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 Standpipes. The Tigard water District owns a 16 inch transmission line beginning at a meter located along Greenburg Rd. across State Highway 217 to Ash Creek. In order meet projected 1995 needs, the following improvements from Bradley Corner to Greenburg Rd. at Ash Creek have been identified. - Installation of a 24-inch line parallel with the existing 16-inch line from Bradley Corner to Highway 217 and installation of a new pressure regulating vault. - Replacement of the existing 16-inch line beneath Highway 217 with a 24-inch line. - Installation of another 24-inch line parallel with the existing 16-inch { line from Highway 217 to Ash Creek. - Development of a second tie to the Portland water system at Haines Road will require installation of a pressure reducing vault on a 12 inch line near Baylor Reservoirs, and construction of a 12 inch line crossing Interstate 5 in this location. Costs for increasing the capacity from Bradley Corner to the District's 24 inch main on Greenburg at Ash Creek and for connecting to the Portland system at Haines Road are 'estimated at $667,000. In about 1995, 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 increased supply from Portland is $5,667,000 for construction. Alternative 3: Joining the Joint Water Commission (JWC) A third supply option under consideration involves joining the 'Joint Water Commission composed of Hillsboro, Forest Grove, and Beaverton. The technical report included in the appendix describes in detail the facilities associated with developing a supply from JWC In outline, these include a 14 mgd raw water R 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 does not include any value that the JWC may set on the'facilit.ies now in place. Alternative 4: Acquiring Water From the Willamette River at Wilsonville A fourth supply option is the Willamette River at Wilsonville. Of the four potentially available sources under consideration, this option would have the most complicated requirements for treatment because of the usage of the watershed j -4- 4 upstream of the intake. Four facilities would be needed to develop a supply from the Willamette, with the intake assumed to be near the mouth of Corral Creek, about 1.3 miles upstream of the Interstate 5 bridge -- a 14 mgd intake, a 36- inch raw water pipeline, a 14 mgd water treatment plant and; a finished water transmission line. The total capital costs estimate for this alternative is $29,690,000. In order to evaluate the relative cost of the various water supply alternatives, a levelized cost analysis was undertaken. A levelized cost analysis determines the cost per 100 cubic feet of water assuming that the same rate would be paid over the study period. This analysis showed the two water supply options that appear the most economically viable to the District over the twenty year planning period to 2010 are the City of Lake Oswego and the City of. Portland options. At present, the district is in the process of choosing one water supply alternative. Future supply-related capital improvement projects depend on the option choosen and this is yet to be done. Bull Mountain Area Water Facilities: The Tigard Water District serves about 1,600 persons in the developing Bull Mountain area. The Bull Mountain area of the Tigard Water District includes some 2,800 acres of residential and agricultural land lying between elevations 200 to 700. Of this, about. 2,140 acres are zoned for residential use and the balance of 640 acres lies beyond the Tigard Urban Growth Boundary, but within the District's planning area. At present, the current water supply is adequate to meet existing demand. The Bull Mountain water distribution system and reservoir site are shown on the "Map of Tigard Water District and Vicinity" and also in Appendix "A" . The District's plan for storage and transmission within the Bull Mt. area envisions the development of a water system from the summit downwards through new residential subdivisions to reservoirs located at intermediate levels. In accordance with a master plan developed for this area in 1986 by Gilbert Meigs, Consulting Engineer, a number of new facilities have been constructed and a reservoir site acquired to serve the developing north and northwest sides of the mountain. The findings and conclusions of this report are discussed and updated in the previously referenced"Water Supply &Water Distribution for Tigard Water District" report. As shown in the master plan, two additional reservoirs serving the south side of the mountain are recommended for eventual construction. One 16 inch line and two 12 inch lines also are needed to complete the installation of major facilities.. The location of all facilities proposed for the Bull Mountain Area are based on a three phase schedule recommended by the "Water Supply & Water Distribution for Tigard Water District" report. The phases extend from 1991 to i005-and beyond and total about $5,000,000. Five-Year Capital Improvement Plan The 5-year capital improvement plan adopted May 1991 by the Tigard Water District is included in this report as appendix "B". This plan contains at least two alternative sets of improvements for each of the five years. All of the improvements are proposed to be funded from system development charges. Metzger Water District The Metzger Water District serves approximately 20% of the population located inside the City of Tigard. The City of Portland's Bull Run Reservoir is the source of one hundred percent of the district's water supplies. The district has i -5- , a contract with the City of Portland for supplies through 2005. The storage capacity of the district's reservoir is 8.5 million gallons. The distribution system is gravity feed and consists of approximately 80 miles of cast iron and ductile piping, ranging in size from 48 inches to two inches. A portion of this system is located within Tigard. A standby pumping system is also available. The location of these facilities is shown in the Metzger Water District Facilities Map. A study of the water system in the early 1980's indicated that the system is an average of 18 years old, a relatively young age for a water system, and that it is in very good condition. $4.75 million of general obligation bonds were sold in 1980 and were usad to fund projects to meet water storage and transmission requirements to the year 2010. District projects planned for the next three to five years within the City of Tigard include: 1) Installation of approximately one and half miles of 16" ductile iron water line from the area of SW Locust and 90th Ave easterly to Oak St and terminating at Pacific Highway and 78th Ave, The cost of this improvement is estimated at $500,000. The funding sources are expected to be 508 general revenues and 50% CIP funds. 2) Upgrade of the existing 3" to 6" line running between Pfaffle and Spruce to all 6" line. This involves the placement of approximately 1500 feet of 6" ductile iron pipe. The cost of this improvement is estimated at approximately $33,000. It will be funded half-and-half by general revenues and CIP funds. 3) The extension of a 12" line from SW 69th Ave to Pacific Highway near 78th Ave. This project would be funded by a local improvement district and would cost approximately $40 per foot. The length of the improvement has not yet been determined but is assumed to be in the 3,600 ft. range. The Property owners participating in the LID will pay the cost of the installation. No list of significant facility projects planned for the longer term is available. This is because the Metzger Water District is in the process of merging with the Wolf Creek Water District. -Complete maps of the Metzger and Tigard Water District transmission, distribution-are available 'at the Water Districts' offices to at d at 6501aSW Taylors Ferry Road and 8777 SW Burnham Road respective) yand from Tigard. These maps are incorporated into this report by,reference,the City of SANITARY SEWER The Unified Sewerage Agency (USA) was formed in 1970 with the authority to collect and treat sewage in the rapidly urbanizing portions of Washington County, including all of the Tigard Urban Planning Area. The agency owns interceptor and trunk lines located inside the,City. It also operates the Durham Treatment Plant, which treats sewage from Tigard and other areas within the Fanno Creek basin of east Washington County. An interagency agreement between the City and USA has been in force continuously since the district's formation. A copy of the current agreement and a related "Cities"/USA Coordination Agreement are attached as Appendices "C" and "D", respectively. Furthermore, the Tigard Comprehensive Plan states in policy 7.4.1: -6- ..J .rF "The Cit shall; T Y w a) Develop a comprehensive sewer plan that identifies the present and future capacity needs for a sewage system in the planning area, and probable routes of tuture trunklines. b) Require that future extensions of collector sewer lines shall be consistent Tigard, Washington C orhe City dinances Unified Un ed Sewage Agency (USA) . of (USA) . c) 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 septic tanks. The City of Tigard owns and maintains the collection system. With few exceptions, its lines are limited to Tigard's incorporated territory. Presently, the City requires that development be connected to sanitary sewer service when sufficient collection capacity in its gravity sewers are available. Tigard has lines to handle expected future development in each basin. Durham Treatment Plant The wastewater treatment plant was constructed in 1978. The current plan operating capacity is 16 million gallons. In 1990 contracts were let for the construction of a new primary clarifier and raw sludge pumping . When completed in late-1993 these and a series of other planned improvements will increase existing design capacity by 50%. The $22.5 million Durham project is being financed by revenue bonds already issued and by the scheduled sale of $40 million in additional bonds in mid-1991. The bonds are to be retired by service charges the sewerage agency imposes on residents and businesses. i Collection System The City of Tigard Sanitary Sewer Facility Plan is attached as Appendix "E". The plan, completed in 1991, shows how sanitary sewer servicleme is thewill epcurrent throughout the Tigard Urban Planning Area. The plan supe U.S.A. Master Plan. it divides the planning area into 68 service areas. This provides sufficient detail to show improvements required to serve each individual parcel within the study area. According to this plan, the condition of existing facilities is generally rated in good to fair condition. An up s attached as adate index oan "Extensions Required to Provide Service to Unsevered Areas, " is appendix to the Sanitary Sewer Facility Plan. Also included as a map exhibit in the facility plan is a summary of areas that are currently served and not served by sanitary sewer. This map also indicates lines that require additional capacity. These lines will be either replaced or parallel lines will be installed. With two exceptions, the Sanitary Sewer Facility Plan indicates that the planning area can be fully served through local improvement districts or by requiring developers to install facilities. The two locations which will require the expenditure of public funds are indicated on the sanitary sewer plan map exhibit in Appendix "E They include: S.W. McDonald Street Sanitary Sewer: A sewer in S.W. McDonald Street will be installed as part of a street capital improvement project. The ; estimated cost of this project was $165,000 and will be completed in 1991. Industrial Sewer Area: The line serving the area bounded 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 1 -7- grade On!iy a portion of the line below S.W. Hunziker was considered for improvement. If demands significantly exceed those expected, improvements above S.W. Hunziker Street will be considered. The estimated cost of this project is $52,000. The Sanitary Sewer Facility Plan makes four recommendations. First, 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 property owners in developed but unsevered areas to fund needed sewers. Third, construction of the industrial area sanitary sewer capital improvement project should be completed during the summer of 1991. Benefitting property owners will likely be assessed for the S.W. McDonald St. sanitary sewer. project. Fourth, the need for improvements to provide increased capacity to portions of 17 U.S.A. and City owned lines identified in the report should be determined by a flow monitoring program. U.S.A. should be notified of the need for improvements that are the responsibility of the Agency. No major transmission line improvements in the area are planned by U.S.A. at this time. STORM SEWER The regional stormwater service provider throughout the urbanized area of Washington County is the Unified Sewerage Agency. In response to new water quality standards for the Tualatin River established by the Oregon State Department of Environmental Quality in 1989, U.S.A. has developed a stormwater management program for the preservation of water quality. The plan addresses non-point source pollution, rainfall-related erosion and sedimentation, and flood control. Furthermore, the City of Tigard has entered into an agreement with U.S.A. to address surface water management functions. This agreement is attachedas Appendix "D". The City is responsible for all storm and surface water facilities within the corporate limits of the City except for those specifically identified on the attached Figure 2, 'U.S.A. Maintenance Areas • The "U.S.A. Maintenance Areas" include the floodplain and wetlands associated with the drainage courses. They are, shaded in blue on Figure 2. The City of Tigard Comprehensive Plan policies provide direction as to how storm water management will be addressed. 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 development study be submitted for development in arias subject to poor drainage, ground instability or flooding which shows that the development is safe and will not create adverse off-site impacts: b) Natural drainage ways shall be maintained unless submitted studies show that alternative drainage solutions can solve on-site drainage problems and will assure no adverse offsite impacts; c) All drainage can be handled on--site or there is an 'alternative solution which will not increase the offsite impact; d) The 100-year floodplain as established b y the 1981 Flood Insurance Study conducted by the U.S. Army Corps of Engineers be protected; and e) Erosion control, techniques be included as part of the site development plan." -8 a � r AV rlk, T I G R D i t' S 1& _ _AREAS 7 , B .

It further outlines the requirements and cost for development of an effective drainage management system. In the ren years since this study was completed many of these recommended improvements have been completed. The "Master Drainage Plan -- City of Tigard, CH2M-Hill is incorporated by reference into this report. The report's introductory chapter outlining its purpose is attached as Appendix "F•. Despite the "Master Drainage Plan's" usefulness, many of its recommendaticns have been superseded by U.S.A.'s Surface Water Management Program. Furthermore, the Fanno Creek Sub-basin Study will likely result in additional changes in the way the City manages storm drainage. Several projects in the "Master Drainage Plan" have yet to be completed. Furthermore, the scope and methodologies associated with these projects will likely be quite different than that originally proposed. This is because of the need to conform to current wetland, floodplain, and floodway management regulations. The following outlines areas where additional storm water management is needed. No date has been assigned to these projects. They will, for the most part, occur as development warrants. Fanno Creek Mouth to Southern Pacific Railroad: This length of the stream is subject to inundation from the 100-year flood on the Tualatin River. Southern Pacific Railroad Tracks to Hall Blvd. Management of Fanno Creek flooding is recommended for this stream reach.. Hall Blvd. to North Dakota St. Channel improvements and six bridge replacements are recommended for this reach of the stream. These include: - Replacing the Hall Blvd. bridge. Improving the storm water carrying capacity of the channel 360 feet '... upstream of the bridge 9,740 feet of downstream, and; - Replacing the Main St. , Grant Ave., Tiedeman Ave., Tigard St., and North Dakota St. bridges. North Dakota St. to Scholls Ferry Rd. Management of Fanno Creek flooding is recommended. Ash Creek Recommended Plan Management of Ash Creek flooding is recommended for theientire length of the stream inside Tigard. 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 crossing to eliminate upstream flooding along Summercrest Dr. if deposition is found to be_occurring ¢' downstream of the existing culvert, a major channel improvement of 1,800 feet is recommended. Tualatin River Recommended Plan Management of flooding along the Tualatin River is recommended for the entire reach of the river that forms Tigard's southern border. -10 x Cast estimates for the recommended drainage improvements are included in the 4 master plan. However, in many cases these cost estimates are not applicable because of the time which has elapsed since they were first developed and the changes that have occurred in storm water and drainageway management practices. The Unified Sewerage 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 maintenance activities. Monies dedicated to transportation projects, such as local bonds and Oregon Highway Division Revenues, may be used to replace bridges. UP-Coming Storm Drainage Projects. In the ten years since the Baster Drainage Plan: was completed, several of the recommended improvements have been completed or scheduled for completion. These include the replacement of 135th Avenue bridge, the planned replacement of the Hall Street and Scholls Ferry Rd. Bridges and the Main St. Bridge. The Oregon Department of Transportation (ODOT) is the funding source for the proposed Hall St, and Scholls Ferry Rd. bridge projects. City of Tigard transportation bond funds will provide the funding source for rebuilding the Main Street Bridge. It is expected that these projects will all be completed within the next three to five years. The estimated costs of the ODOT projects are unknown. The Main Street bridge is estimated to cost $710,000. TRANSPORTATION The location of Tigard's arterial and major collector streets is indicated on the attached Comprehensive Plan Transportation Map, Figure 3. The City of Tigard works closely with the Oregon Department of Transportation and Washington County, and METRO in planning for increased capacity and level of service for the area's arterial and collector network. In this regards, the Tigard ComprehensivePlan Mates in policies 8.1.1 and 8.1.2 respectively: "The city shall plan for a safe and efficient street and roadway system that meets current needs and anticipated future growth and development.." "The City shall provide for efficient management of the transportation planning process within the city and metropolitan area through cooperation with other federal, state, regional, and local jurisdictions. The general condition of the arterial and collector network within the planning area is fair to good. The state, county and city all maintain their respective roadways. The City of Tigard has developed a pavement management program for roads under its jurisdiction and engages in a systematic program of maintenance. Short Term Transportation Projects: 1991-1995 Numerous Tigard area street improvement_projects are listed in the current and proposed Oregon Department of Transportation (ODOT) Six Year Plan (1991-96) . . r ODOT's Six Year Plan for the Tigard area is incorporated by,reference into this report. It is available at Tigard City Hall.' ODOT is the exclusive funding source for all of these except one. The Pacific Highway at Gaarde St. project y assumes City participation. Matching funding is proposed to come from the City's "Major Streets Traffic Safety Improvement Bond Sale."" This $8.5 million general obligation bond that provides funding for improvements to segments of ten major streets in the City was passed by Tigard voters in 1988. The projects were initiated in 1989 and are ongoing. This improvement-program-is anticipated to be finished in 1991. These improvements will solve several of Tigard's street capacity and safety problems. The Road Bond projects are shown on Figure 4. -11- 1 FIGURE 4 CIT OF TOGARD0AQ BOND PROJECTS qcc o e CITY I QF TIGARD TAYLORS FFq�r RO. ` 40 40 LOCUST > o ST. . m SCttoLLS > W', W a �Tm a NORTH DAKOTA ST_ rn PFAFFI_E to 14 t y�1- In y v W.

Major ODOT I-5 Improvement Projects: The Oregon Department of Transportation has completed preliminary engineering for a project to improve traffic flow and capacity at the interchange between Interstate 5 and Highway 217. ODOT is currently evaluating the impacts of a number of realignment alternatives on traffic flow, adjacent land uses, and other aspects of the environment. Construction is anticipated in 1994. The general areaa of the project is shown by Study Area 6 on Figure 3. City of Tigard Bridge System: An inspection of all the bridges located inside the City was completed by CH2M Hill in 1990. Among other items, the inspection reports included bridge component condition ratings and recommendations for maintenance or repair. CH2M Hill's report did not provide cost estimates for those bridges that need rep!,Ar. These will be incorporated into the Public Facility Plan as they become available.

Bus routes inside Tigard are shown in Figure 5. The City has also identified corridors for the extension of light rail on its Comprehensive Plan Transportation Map, Figure 3. Furthermore the City's Comprehensive Plan states in policy 8.2.1: "The City shall coordinate with Tri-Met to provide for a public transit ' system within the planning area which: a) Meets both current and projected needs for the Tigard Community; b) Addresses the special needs of the transportation disadvantaged; C) Reduces pollution and traffic; and d) Reduces energy consumption In 1988, Tri-Met, the regional public transit agency, completed construction of a transit transfer station on Commercial Street in downtown Tigard. Plans are currently underway for the construction of a park and ride station located at as yet undetermined siteonPacific Highway in Tigard. The size, 'design; and parking capacity of the facility also have not been determined as yet. A summary description of the proposed Tigard Park and Ride is attached as Appendix "F•. The eventual extension of a light rail line is in the conceptual stage. The City of Portland has engaged a consultant to undertake preliminary planning or systems level analysis of potential light rail alignments in the Barbur.Blvd. Corridor between downtown Portland and Tigard. This study will also examine potential light rail service to Washington Square. Tigard Area Comprehensive Pedestrian-Bicycle Pathway 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 { -15- i r updated in 1985 and is included as Figure 6. Future updates of the Pedestrian- AMW Bicycle Plan will be incorporated into the Public Facility Plan as they are developed, The City of Tigard Comprehensive Plan provides policy direction for bicycle and pedestrian facilities. The plan statas in policy 8.4.1; "The City shall locate bicycle/pedestrian corridors in a manner which provides for pedestrian and bicycle users safe and convenient movement in all parts of the city by developing the pathway system shown on the adopted pedestrian/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 required to provide for bicycle and pedestrian paths when developing adjacent to a floodplain, city designated greenway, or wetland. Short Term Bicycle/Pedestrian Path Proiects: In addition to bikeways to be constructed as part of street projects, the City will implement five major bikeway projects as part of the Tigard Three Park Levy which was passed by Tigard voters in 1989. The estimated cost of this effort is $364,000. The projects involved include: - Reconstruction of 1.5 miles of Englewood Park Paths. - Connecting Durham Road and Cook Park along 92nd Avenue. - Extending the Path/Finder Genesis Trail approximately one mile., and; - Connecting Cook Park and 113th Avenue. -16- f i t LIST OF FIGURES, APPENDICES AND TECHNICAL REPORTS AND FACILITY MAPS INCORPORATED BY REFERENCE FIGURES 1.

INTRODUCTION Tigard Water District continues to increase its water supply requirements,but its Epnmary supplier, the City of Lake Oswego, is increasingly unable to meet the District's hot weather needs because Lake Oswego,too,has increasing needs for ` ! supply. In response to this situation, and because Lake Oswego now has received an engineering report on expansion of its supply system that could involve the District, the District retained Economic and Engineering Services, Inc. (EES) to prepare this study of future sources, including Lake Oswego and three other alternatives. Additionally, &rowth continues within the Bull Mountain area, and the District included a review of facilities to provide water to and within that area. Finally, long term replacements and reinforcements as well as main extensions to serve new customers has continued in the"410"zone. The District included a review of the mains and storage within this, the preponderant zone within the 4 District,to provide a more complete study of all waterworks facilities. t 2. PROJECT AUTHORIZATION This report isprepared in accordance with the contract made on October 11, �. 1989 between the Tigard Water District and EES. 3. FINDINGS AND CONCLUSIONS 7 A Flow Rates for Supply Planning Flow rates are based on records from 1986 through 1989, with extrapolation t based on population forecasts made by the Metropolitan Service District and Washington County Planning Division through the year 2010. (, Populations,average flows and peak flows recorded and forecasted are: 1 . Average Peak ( Year Population Flow Flow 1987 27,529 3.83 mgd 8.10 mgd ( 1995 36,934 5.50 mgd 12.70 mgd , 2010 45,607 6.80 mgd 15.70 mgd The peak flow forecast for year 2012 made by CH2M Hill for the Lake Oswego "Water System Master Plan" in 1988 is 16.9 mgd,virtually the same as by EES if the 2010 flow is extrapolated for two years. t . , l I 1 ■ B. Water SuoDly Facilities and Capital Costs 1. In the fiscal year 1988/89, the District bought 92.8% of its supply from Lake Oswego and 3.7% from the City of Portland, and pumped 3.5% i from wells at Stations No. 1 and No.2. 2. Basic sources considered in this study and their exposure to raw water contaminants are: Source Owner Famosure Level Clackamas River Cit;f of Lake Oswego Average Bull Run River City of Portland Least Upper Tualatin River Joint Water Commission Minor Willamette River Tigard,if developed Worst (� Regulations being developed by the State and Federal authorities will - 1 ` most likely add to the cost of all sources, but it is impractical to attempt to quantify the cost impacts. I3. Lake Oswego sells surplus water, and in hot weather is unable to fully supply the District. Lake Oswego is considering expansion of its suply system on the Clackamas River to serve (1) only its own needs or (2�its needs and those of the District. The present and proposed point of 4 delivery to the District is the 4.0 mg Waluga reservoir at elevation 320, which is 90 feet lower than the District's receiving reservoirs. The District owns a system of pi lines and a pamping station. on Bonita Road to �... transmit water from Waluga reservoir to the District. The District has been well-served by Lake Oswego for nearly 20 years. Growth within Lake Oswego now has reduced peak surplus water for Tigard to about 4 mgd and the forecast is for no surplus peak supply in 1997. "Scenario 2" of Lake Oswego's Master Plan includes provision for all of the District's needs until 2012 by construction of a new intake,water treatment plant on the Willamette River,pipelines,and pumping stations in addition to expanding existing capacity on the Clackamas where feasible. The capital costs allocable to the District are estimated at: Year Cost 1991 $18,297,004 Between 1997 and 2004 $2,296,000' To enable the District to transmit the expanded supply, another pumping station will be needed on Bonita Road and the 24-inch transmission line will be extended on McDonald Street westerly to Gaarde. The capital costs related to this work are: t Year Cost 1991 $839,000 Realistically, no expenses of these magnitudes will be made until the j I-2 g f t ( District and Lake Oswego make major policy decisions. The first phase probably would extend from 1991 to 1994. Bearing this in Hund, the schedule and total capital costs for a firm supply from Lake Oswego amount to: i Year Total Capital Costs 1991 to 1994 $19,136,000 t Between 1997 and 2004 2,296, Total $21,432,000 If the District were to commit 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 is the Bull Run River,and it is backed-up by a groundwater supply for intermittent use. There is an adequate supply((, pply at Bull Run, but the future nature and cost of disinfection, Lt impoundment utilization and additional transmission lines are not yet defined by studies now in progress. fThe District is now under contract with Portland to purchase at least 3.6% of its sales from a meter at Bradley Corner. This water is transmitted onward to the District through a pressure-controlled system of pipelines. Portland has advised EES that 6 to 8 mgd now are available at Bradley Comer. The residual pressure is adequate for gravity flow to the 10 mg LL, reservoir on Bull Mountain. Further, Portland states that there is a potential 1 mgd now available on the east side of Highway I-5 at Haines Road and that 3 mgd will be there available in 1993. Portland further states that a new transmission system will be needed to meet the District's forecasted peak demands of year 2010. EES estimates __. that this system will be needed in 1995, although storage utilization and/or conservation may postpone the need for a few years. Costs for increasing the capacity from Bradley Corner to the District's 24- inch main on Greenburg Road at Ash Creek and for connecting to Portland at Haines Road are estimated at $667,000 and would be scheduled for FY91. In about 1995,about$5,Aa0,000 will be needed for a ti new system to Bradley Comer. The allocation of this cost has yet to be made. Thus, the total,assuming Tigard pays all capital costs, for a supply from Portland is$5,667,000 for construction. 5. Hillsboro, Forest Grove, and Beaverton operate a Joint Water Commission that manages treatment, treated water storage, and certain Enear Dilley. Treated water originating in the Tualatin River headwaters, Scoggins Reservoir, and the Trask River Darn is sold by the Commission to its members. Transmission to Hillsboro and Beaverton is by means of pipelines jointly owned by those cities. I-3 t Each member city owns its own water rights to free-flowing and stored i water. Were the District to join. the Commission, it should expect to assist in financing storage at Trask River or at the Mt. Richmond Reservoir site being studied by the U.S.Bureau of Reclamation.' Were the District to join the Commission,it should also expect to finance, initially, 14 mgd of intake, treating, and pumping capacity at the ( Commission's plant site,a 30-inch pipeline about 5,000 feet long from the ( intake through the plant and to a reservoir at elevation 520, a portion of another reservoir at the same elevation, and about 93,000 feet of 42-inch pipe onward to the District's 10 mg reservoir at elevation 470. The capital cost of this first phase is estimated at$35,760,000,including cost of storage at Trask River Dam. Treatment is expected to include pre- ozonation,coagulation,sedimentation,filtration and disinfection. In about year 2000, a 4 mgd addition to intake, plant, and pumping capacity is forecast, at a capital cost of$2,100,000. Thus, the total cost estimate for a supply from the Joint Water Commission is estimated to be about$37,860,000 No allowance is made ` for any allowances for values that might be set on facilities now in place. About 44% of the cost is for pipelines. The route chosen for this study passes near the Wolf Creek Highway Water District and the City of Beaverton. If this alternative is selected for further study,cost sharing of ^'^clines :=.^.th these entities should benefit the estimated cost for the )Figard Water District 6. The Willamette River at Wilsonville has beer,a source of interest to the District since 1973. New questions as to the availability of"free water" have arisen and ever-increasing regulations dealing with contaminants in drinkin& water have clouded the cost of water question. Before any L : design is undertaken, a raw water quality testing program should be implemented. For the District to draw on the Willamette River as a source of drinking water,this study assumes an intake 13 miles upstream of highway I-5 and a 6,500 foot line to a 14 mgd treatment plant west of Dammasch State Hospital. The treatment process of' pre-ozonation, coagulation, sedimentation, filtration and disinfection, would be supplemented with granulated activated carbon beds for synthetic organic removal. Pumps �` at the treatment plant would force water through about 54,500 feet of 36- inch line onward through a route that passes the Cities of Tualatin and Sherwood enroute to the District's 10 mg reservoir. The capital cost of s this first phase is estimated at$26,950,000. In about year 2000, a 4 mgd addition to intake, plant and pumping capacity is forecast at the capital cost of$2,740,000. Thus the total cost estimate for a supply from the Willamette River is estimated to be about$29,690,000. 1 1-4 � I If this alternative is selected for further study,cost sharing of the pipeline capacity with Wilsonville, Tualatin, and Sherwood should benefit the District's costs. C.Ann al Costs of Alternate�,-.- Py- 1. In addition to debt service on capital costs, there are recurring costs for treatment labor, chemicals, in-plant power, for pumping power, and where appropriate,for costs of water purchased. j 2. Debt service is based on uniform annual payments to retire 20-year bonds J bearing 7.5%v interest. Chemical and labor costs vary with the source. Power is based on the current Rate Schedule 32 of Portland General -� Electric. 3. Financial studies yield the following results based on levelized annual costs over the 20 year planning period: City of Lake Oswego $1.158/ccf City of Portland $1.098/ccf Joint Water Commmission $1.723/ccf Willamette River $1.683/ccf We recommend that the District further investigate the City of Lake . Oswego and City of Portland water supply options to determine the most favorable based on cost and management considerations. D.Facilities for the Bull Mountain Area 1. Growth within this area, which is that part of the District receiving internally pumped water, is forecast at 70 households per year. Peak { usage is forecast, for year 2010,,at a rate of about 75% of presently installed internal pumping capacity. Completion of the 12-inch line to High Tor from SAS 132ndd Avenue on the north side of the mountain will k soon be needed. Another 12-inch line, this from Bull Mountain Road to the 12-inch line from S.W. 132nd, should be constructed. Phasing and total costs are: Phase Year Total Cost 1 1991 $126,000 2 1995 $65,000 1 i 1-5 t 2. Within the Bull Mountain area, reservoirs proposed in the 1986 study are still proposed. A section of 16-inch line is needed on Beef Bend Road to connect the lower area of the Barrington subdivision into the "410"zone. �y No additions are needed at High Tor pumping station,but a 12-inch line J from its discharge main to Three Mountains subdivision is needed for ire protection. The 16-inch line proposed in 1986 to a reservoir on S.W. 150th and a 12-inch line on S.W. 150th to Hawkridge Road are still proposed. Phasing and total costs are: Phase Year Total Costs ; f 1 1991 $158,000 2 1995 $1,200,000 3 2000 and beyond $3,363,000 E Improvements within the"410"Zone 1. Few improvements appear to be necessary and are confined to J reinforcements of the water network. 2. In 1986, pipeline improvements to fill Reservoir No. 3 were proposed. This recommendation is continued. Twelve-inch lines around King City, 12-inch lines from Walnut to North Dakota Street and on North Dakota, and a 12-inch line on Scholis Ferry Road from S.W. 135th to Fem are recommended. 3. No further storage at Stations No. 1,2,3,4, or Baylor is recommended in this report,but land recently made available for other use at Station No. 1 should be kept for additional storage in several decades. 4. Phasing and costs are: Phase Year Total Costs 1 1991 $5000 J 2 1995 $591,000 3 2000 and beyond $330,000 t l j r l 1-6 APPENDIX ECONOMIC AND ENGINEERING SERVICES, INC. 4380 S W.Macadam Avenue.Suite 365 Portland.OR 97201 15031 223 3033•FAX(503)274-6248 May 8, 1991 File aY: 60030 Mr. John•Miller Administrator Tigard Water District 8777 SW Burnham Road Tigard, Oregon 97223 Re: 55-year Capital Improvements Plan Dear Mr. Miller: Pursuant to your request, Economic and Engineering Services has prepared the attached 5-year Capital Improvements Plan (CIP) for the District. The CIP contains at least two alternative sets of improvements for each of the five years. In preparing this_CIP,we have employed reports prepared by the writer in 1971, 1986 and 1990 after discussions with District staff to ascertain project work completed within the last year and to ascertain projects that the District expects to be largely financed by property developers. All of the pipeline and reservoir projects proposed will increase the system capacity and thus may be financed from the full System Development Charge(SDC). It is our opinion that the telemetry system, however,may be financed from the reimbursement component of the SDC. The alternatives are proposed so that changes of events may be accommodated and the internal specifics to the CIP may be reshaped as the years pass. In each year, the total CIP cost is the same, regardless of alternative chosen. In order to make the total yearly cost equal, we have adjusted the amount reserved for future reservoir construction. A note on the last page of the CIP contains information on the minimum and maximum accumulation of funds into this reserve. Very truly yours, ECONOMIC AND ENGINEERING SERVICES, INC. Gilbert R.

Pi eline Extension: S.W. MacDonald Street Hall Blvd. to Pacific Highway, 5,100 feet of $367,200 24" D.I. pipe @ $72/ft Justification: "This is the last phase of the instal- lation of a 24-inch transmission main, paralleling a 16-inch main, (or 30-inch equivalent) from Lake Oswego's Waluga Reservoir to the 10-MG (terminal) reservoir located on SW 125th and Bull Mountain Road. This provides the district with its primary source of water supply, the Clackamas River via the City of Lake Oswego. The City of Tigard plans to widen McDonald this year and this pipeline should be installed prior to the widening. A2. Future Reservoir Site: Purchase 2 acres of land near Mtn. Gate subdivision on Bull Mountain for future 100,0002.5-MG reservoir at elevation 550 feet above sea level z; Justification: An engineering study of 1986 advised that sites for four (4) new reservoirs should be purchased before the land was taken up for houses. This is the last of the four sites to be purchased upon which a 2.5-MG reservoir project will begin FY 95/96. 1 A3. Reserve for construction of future 2.5-MG reservoir to be located at S.W. 141st Avenue, between Beef Bend Road and Bull Mountain Road 36,000 Justification: The district has adopted a policy of paying for needed capital improvements from current revenue. Engineering studies of 1986 and 1990 advised that to keep up with growth, the district must construct a 2.5-MG reservoir near SW 141st on Bull Mountain. This will provide the district with a total of 23.5 million gallons of storage. The reservoir will serve all residents below elevation 350 feet above sea level on the south side of Bull Mountain. The expenditure is too large to accrue in one or two years and this is just the start in savings for that reservoir construction.

Pipeline Extension: S.W. 121st and Walnut Street, from Former to 135th Avenue, 5,600 feet of 24" D.I. pipe @ $72/ft $403,200 _jus*d-ficaton: In the summer time, No. 3 reservoir will not fill because the pipelines serving it are too small. With high growth in this area, along with the requirement that water be pumped from the 132nd Street pump station to High Tor, it is deemed important that this main be installed as soon as possible. Additionally, fire flows are deficient in some parts of the area. The engineering study of 1986 recommended that this main be constructed. If the City defers the MacDonald street project, then this pipeline would be built. B2. Future Reservoir Site: Purchase 2 acres of land near Mtn. Gate subdivision on Bull Mountain for future 2.5-MG reservoir at elevation 550 feet above sea level 100,000 Justification: An engineering study of 1986 advised that sites for four(4) new reservoirs should be purchased before the land was taken up for houses. This is the last of the four sites to be purchased upon which a 2.5-MG reservoir project will begin FY 95/96.

If this project is not built in FY 91/92, then it should be built in FY 92/93. A2. Telemetry System: New telemetry system to monitor and record data about all pump stations and reservoirs 150,000 Justification: With the huge growth in the Tigard area it is now impossible to monitor the water system without an updated telemetry system. This system was recommended in the engineering study of 1971. It allows one person to monitor the water system at a glance. Problem areas can be identified immediately and resolved without long lag times. Major leaks and main breaks can be identified and located within minutes, instead of hours.

This 24-inch main will parallel an existing 16-inch main and will allow higher flow rates to be purchased from Portland to meet the demands of the district well beyond year 2000. An equivalent 30-inch main (16-inch plus 24-inch) was recommended in the'engineering study of 1971. This line would be built in FY 92/93 if the City of Tigard cancels MacDonald street widening or if there is a material decrease in the supply for Lake Oswego. C2.

INTRODUCTION The goal of this study is to provide a plan for ensuring adequate sanitary sewer service throughout the City when felly developed. This will require accomplishing the following objectives: - Ensure that lines constructed for new developments can be readily extended to serve other areas within the basin as development occurs; Provide a guide for providifig- sewers to developed but unsewered areas within the study area; Identify portions of the future collection system that should be considered for a capital improvement project; and Determine adequacy of each existing line to meet the demands from the area it serves when fully developed. The plan is for the area described on the City's Comprehensive Plan Map - Land Use, as the Urban Planning Area Agreement. In 1970, the City entered into an agreement with the Unified Sewerage Agency of Washington County that provided that the City would enforce construction standards, rules and regulations, and rates and charges governing the use of and connection to the City's sanitary sewerage system. In turn, U.S.A. agreed to provide trunk and interceptor lines, as well as treatment facilities. In 1985, the U.S.A. adopted the Master Plan Update as its current plan. That plan was an update of the Tualatin Basin water and Sewerage Master Plan prepared for Washington County 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 within the City's Planning Area Agreement. This will provide sufficient detail to show improvements required to serve each individual parcel within the study area. 2 . EXISTING FACILITIES 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 inspection program. Damaged or improperly constructed facilities were repaired as encountered resulting in a system that is generally rated in good to fair condition. City staff has prepared an index map of existing facilities from as-constructed-drawings. The map is continuously revised as as-constructed drawings are received. SANITARY SEWER FACILITY PLAN PAGE 1 r 3 , SYSTEM EVALUATION The system was evaluated by first determining the adequacy of the capacity of existing lines to meet expected demands. Next, the sewer extensions necessary to serve areas currently unsewered were determined. 3.1 Capacity of Existing Lines The U.S.A. Master Plan included an evaluation of the capacity of the larger existing lines within the City. Improvements were recommended to accommodate various extents of development; short term improvements are required for existing development, long term improvements for development expected to occur by 2005, and improvements required for ultimate development. Recommended improvements require that lines with inadequate capacity be either replaced or provided with a parallel line as shown on TABLE 1. The location of the improvement required for expected increased demand are shown on Map 1 by project number. Anticipating the need for these improvements can be best accomplished by monitoring the rate of flow in the manhole immediately downstream of the proposed improvement. By projecting the increased rate of flow, the time the proposed improvement will be required can be determined. Future development at less than expected intensities may eliminate the need for some of the proposed improvements.

Anticipated wastewater flows into the sewer are expressed in gallons per acre per day (gpdd) . The various sources of flows shown are described in the U.S.A. Master Plan Update. Domestic flows are determined by using 70 gallons per capita per day as suggested by the Master Plan and 2.3 persons per housing unit as reported by the Portland State University Population Research and Census Center. The rate of inflow/infiltration is the rate expected of a system in good to fair condition without storm drainage connections. With the exception of the line serving the area bounded by Sw Pacific Highway, Interstate 5, and Highway 217, all of the smaller existing lines have adequate capacity for future expected development.

SANITARY SEWER FACILITY PLAN PAGE 4 ` 3.2 Recguired Extensions Many areas within the City are completely served and are not in need of improvements except perhaps for the extension of an existing line to serve an individual parcel. These areas are shown on Map 1.. Improvements required to completely serve the other service areas are shown in APPENDIX 1. Unless otherwise shown, the improvement requires the extension of a public 8-inch sanitary sewer to the- area or tax lot indicated. The service area boundaries and proposed extensions are shown on the maps. 3.3 Recommended Cayital Improvement Pro3ects With the exception of the two projects noted below, the planning area can be fully served without publicly financed capital improvement projects. Developed areas may be provided with sewers as shown on the Facility Plan maps with financing provided by Local Improvement Districts specifically formed to construct the sewers. Sanitary sewers for undeveloped and developing areas could be provided by developers as the demand requires. S.W. McDonald Street sanitary sewer - A sewer in S.W. McDonald Street will be installed as part of a street capital improve- ment project. The line will not be functional until it is extended across S.W. Hall Blvd. to the Fanno Creek Interceptor. These improvements will permit abandoning a pump station on S.W. McDonald Street. The estimated cost of the project of $165, 000 shown in TABLE 3 was determined using the Master Plan Update (Engineering News Record CCI of 4600) method and does not include the portion of the line installed as part of the McDonald St. capital improvement project. Moreover, if financing is provided by a Local Improvement District, the cost of adminis- tration of the District should be added. Industrial Area Sewer- The line serving the area bounded 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 grade, causing a mainte- nance problem because of grease accumulation at a manhole. Only the portion of the line below S.W. Hunziker Street was considered for improvement. If demands significantly exceed those expected, improvements above S.W. Hunziker Street should be considered. Since design and easement acquisition is nearly completed for this project, only a 15% construction contingency was added to SANITARY SEWER FACILITY PLAN PAGE 5 Al i the expected construction cost to determine the total project cost of $52,000 as shown in TABLE 3. The expecten construction cost was determined by detailed estimated quantities rather than the Master Plan Update method.. TABLE_3 PROPOSED CAPITAL IMPROVEMENT PROJECTS Proiect Total Cost S.W. McDonald St. $ 165,000 Industrial Area $ 52, 000 4 . RECOMMENDATIONS A. Sanitary sewer service should be extended to undeveloped areas as development occurs. The sewers should be provided by the developer and installed as described in Section 3 and APPENDIX 1. B. The City should continue its policy of facilitating agreements among owners, in developed but unsewered areas that will fund improvements required to provide sanitary sewer service. As with undeveloped areas, sewer extension should be installed as described in Section 3 and APPENDIX 1. C. Construction of the Industrial Area sanitary sewer capital improvement project should be completed during the Summer of 1991 as currently proposed. The S.W. McDonald St. sanitary sewer- project should depend upon the benefitting 'owners providing the funding. D. The need for improvements to provide increased capacity as shown on TABLE 1 and MAP 1 should be determined by a flow monitoring program conducted by the Wastewater Division.- Each winter; the depth of flow, time, and date should be recorded SANITARY SEWER FACILITY PLAN PAGE 6 s ..

Implementation of the drainage plan should reduce the public cost for storm sewers, channels, culverts, ' and bridges and lower the costs for maintenance and rehabilita- tion following floods. The drainage pan identifies both existing and future drainage problems. The goal of the master plan is to eliminate those problems through a defined j implementation process. The master drainage plan prepares a course of action for implementation and maintenance of urban drainage works through corrective and preventive measures. Corrective measures seek to mitigate flood damage potential that has been created by the urban development encroaching on the natural flood plains. Preventive measures are achieved through flood-plain management with the objective of reducing both minor and major storms' damage potential before future development can encroach on the flood plain. Master drainage planning for the urban drainage network is based on the premise that two separate and functionally distinct drainage systems exist. The first, or minor, system accommodates the storm runoff expected once every 2 to 10 years. It consists of property line swales, streets and gutters, storm sewers, and smaller open drainageways. It provides convenience drainage, reduces street maintenance costs, and directly affects the orderliness of an urbanized area. The second, or major, system handles runoff from 1 the 100-year storm runoff event in order to prevent loss J of life and major damage. Storm rur_off follows the major drainage system route during a major storm, ,whether or not the route is planned or development is wisely situated vela -T� tive to that 'route. The 100-year storm is studied to ensure compatibility with state and Federal flood-plain manage- ment policies, although facilities may, in some cases, be designed for lesser events for economic reasons. In these cases, the effect of the 100-year storm is considered when assessing the impact of the improvements. aThroughout this report, "existing conditions" refers to the conditions in 1979, 'when both the COE's and CH2M HILL's hydrological studies were conducted. "Future con- ditions" refers to projected conditions of development or land use in the year 2000. 274A 1-1 i The management strategies developed in this plan are for open drainageways because they provide the basic outlet for bath minor and major stormwater in each drainage basin. If the open drainageways are not preserved or improved, they will not be able to handle increased amounts of storm- water runoff, which can be expected as further urbanization takes place. The planning effort in this study has concen- trated on the drainage system of Fanno Creek and its two major tributaries, Ash Creek and Summer Creek. However, Many of the plan recommendations will be applicable to other drainage systems outside Fanno Creek. In addition, the problems of flooding on the Tualatin River are identified. Many demands are being made on the land and water resources in the Tigard area. These demands are associated with ef- forts to achieve a variety of objectives, such as economic development, local and regional development, transportation, social well-being, and environmental quality. Because land resources are limited, these objectives compete with one another. Those that concern the drainage system will be reconciled through a formal drainage planning strategy that includes: • Identification of the comprehensive goals and policy objectives of the City of Tigard and its surrounding urban growth area • Hydrologic simulation of drainage basins for a range of drainage strategies that reflect existing and expected future conditions of development • Delineation of flood hazard areas • Identification and evaluation of a range of drain- age management alternatives, including corrective and preventive measures - • Recommendation of a proposed course 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 planning process there has been an attempt 1 ti combine urban runoff management with other urban systems 1 to enhance the overall urban setting. Many urban drainage systems can accommodate other benefits besides achieving ` the purpose of stormwater management. Systems that are more functional can be achieved economically by integrating the urban systems. Some of the secondary benefits efits realized through an effective drainage program include reduced street construction and maintenance costs, an improved public health environment, lower costs for open space and park areas, and development of otherwise undevelopable land. 1-2 274A The master drainage planning process results in production of a recommended plan for management of the open drainage- =� ways. The plan is a product of engineering and economic studies of the present physical environment and of the ex- pected development changes through the planning period (the next 20 years) . Throughout this planning process, input from municipal of- ficials has been solicited to ensure compatibility of the recommended strategies with the City of Tigard's goals and objectives. 4 I l 4 1 _1 274A 1-3 �t APPKNDIX , G TIGARD PARK & RIDE I. PROJECT DESCRIPTION The proposed project consists of ,design and support sarvices and construction of an approximately 200 space park and ride in Tigard, Oregon. The project would include between 175 - 200 parking spaces, land- scaping, sidewalks, bus stop improvements on Pacific Highway, and lighting. The exact number of spaces will depend on the final design of the lot and the extent to which a water detention feature will be required on the site. Please refer to exhibit 2. The project will be constructed on land provided by the Oregon Department of Transportation. Total UMTA-eligible project costs are estimated at $335,000 for design and construction. A cost allocation plan will be sub- mitted at a later date. A cost breakdown is provided in exhibit 1. II. PROJECT JUSTIFICATION The Transit Development Plan Update adopted by the Tri-Met Board of Directors in 1987 calls for improvements to transit service and facilities in the Tri-Met District, including construction of a Tigard Park and Ride. The Tigard Park and Ride is an important part of Tri-Met's Plans to improve transit service in the 99W Corridor. The Tigard Park and ride would provide an opportunity for current and potential transit patrons to access the trunk line service in this corridor. Today, the lack of transit trunkline or feeder service in the high growth areas north and south of 99W is deterrent to transit usage. The existing Park and ride facility on Barbur Boulevard, approximately 3.2 miles northeast of the site, is over capacity despite recent modifications to increase the number of spaces. A significant amount of unauthorized park and ride activity currently occurs at a number of locations along the 99W trunkline route. These existing riders may be lost as unauthorized park and ride spaces are lost to redevelopment. Expanded park and ride capacity will allow for increased transit ridership and is expected to contribute to the amelioration of growing congestion levels along Pacific Highway. The proposed facility is the outgrowth of a cooperative planning effort (} involving Tri-Met, the Oregon Department of Transportation, and the city of Tigard to provide expanded park and ride capacity in this corridor. E { III. ENVIRONMENTAL DOCUMENTATION An Environmental assessment (EA) was completed in December 1989. Tri-Met enlisted the cooperation of other agencies and jurisdic- tions in the environmental review. The findings of the EA are that no significant environmental impacts will result from the project. A Finding of No Significant Impact is requested from UMTA for the project. IV. PROJECT IMpL.. -TEMPLAN Final design of the Park and Ride lot is expected to commence in August - September of 1990 and extend through March of 1991. The timing of construction will depend on acquisition of the site, which is expected between January and September of 1991, depending on the availability of Federal Highway Administration funds. ` Construction will commence as soon as possible after land acquisition and will take approximately four months. ,Encumberment and Disbursement Data Estimated Estimated Est.
