The following guidelines are suggested by staff: 41„ 1. The Commission be willing to grant a fill permit based upon the submission of a basic Hconcept proposal" if it can be /44 found to n3t violate the intent and purpose of the Flood ,1'.. Plain Ordinance. Using the concept as the basis of approval, the following standards are suggested as conditions to be met by a more detailed plan which would be submitted prior to any actual site work. i A. That before initiation of any filling or regrading, a lk i detailed site grading plan, meeting APWA and UBC standards, will be submitted to the Planning Commission for their approval. The submitted plan should include a sufficient number of cross sectional diagrams to enble the Public Works Department to properly determine compliance with the Flood Plain Ordillance and any conditions imposed by the granting of the permit. , t ,o, B. The submitted detailed plan should include the following ,) , ,, „ elements: ,.., 1. stream bank protection measures 2. stream banks of gentle enough slope to resist erosion , ft' and also to be aesthetically pleasing ;,.., 3, a landscape plan - f ,. 4, compatibility with the proposed Oreenway System, especially in terms of topography, which retains the ,',. _, -, natural aspects 01 the area adjacent the stream . 4 1.,„, ut . while providing for a bicycle/pedestrian path lo- l' :0 cation.

Box 23557 Tigard, Oregon 97223 CITY OE TIGARD Re: Flood Plain Ordinances Dear Wink: I have examined the alternative Flood Plain Ordinances being considered and offer the following commentary: ENGINEERING CONSIDERATIONS. Engineering requirements imposed by the ordinances should not resul: in either excessive costs or delays. There is, or should be, a Sufficient amount of existing data so that determination of 100 year flood elevations with, reasonable tolerances should be readily calculable by any competent Civil Engineer. Further, it is, most obviously, a responsibility of the professional • Civil Engineer to recognize drainage as a primary consideration, and he should not have any difficulty in coping with the specific ordinance teqdirements. PLANNING CONSIDERATIONS Of course, as You have recognized, the 100 year storm flood plain iS subject to both poSitive and negative changes due to develop- ment on the one hand, resulting from greater impervious areas, and channel improVement8 or flood control methodS, on the other hand, resulting in reddction of maximum flood heights. Ih my opinion, the latter, that iS reddction and/or containment • of flood , is both hedeSSary and inevitable and for reasons of both the. Constantly changing flood zone areaS and the indication of futUre control of these prgbleins, favor the Flood Plain Overlay District" rather than establiShing specific flood plain 119 OW.

That is, ,the City of Tigard should have a plan designating the .future use of those areas and an ordinance prohibiting that use until certain conditions are met, i.e. removal from theflood plain without adverse effects, on other properties. By using the. Overlay, the City of Tigard would accomplish the coilowing 1. Enable the.

Allow for automatic adjustment of flood plain prohibited construction areas as conditions change without rezoning and/or comprehensive plan changes. 3. ethe latitude necessaryto allow some desirable development t .in the, designated flood plain areas under other than adversative' conditions. For example, by regrading and relocation of water storage areas, some development may be desirable and workable with- out reduction in the flood storage cclpacity of the drainage basin.

Brooks said yes that this was the intent and that uses allowed would be defined by the underlying primary zone. C. Barkhurst stated 'his belief that thea,Plahning Commission • should hold another public hearing to allow more time for consideration of this important issue. He said the Washington county Flood Plain Ordinance , takes a different approach from the one being proposed by the Planning staff and he WoUld' like. more time to research their methods. He stated his preference for the Washington, County Ordinance because it resulted in allowing some development to take place .in the fl . PP flood " plain if the applicant could prove' no detrimental effects would occur. He disliked proposed ordinance because it would stop all development for a 2 year Period. U. Brookssaid that without a proper engineering study there is no basis for the City to evaluate the develop- ers proposal to ascertain if detrimental effects Would be proposed. E. Barkhurst said, its raise the question, is it fair to stop all development because the City has failed to carry out a study " • F. Al- Gerrard from the Washington County public Works office stated that the countyfs original Ordinance was similar to that being proposed by the City, but he then stated his opinion that the Citygs proposed ordinance Was too drastic a measure. He said the Ord -, Y,' inahce Which the County is proposing allows the devel - ; o er toplace certain develo ments in flood plain P p the . if he can prove that he Will not back Water oh his g , cease downstream flooding, or ih any net hbor . inc . way displace water onto adjacent property.

Fi‘e'-if, dersof said that the Was'11 ;;,ton County Ordinance had much to commend it 'and stated his belief that the ordinance proposed by the Planning Department was not yet ready to go to Council. He continued by saying the ordinance needed some type of conditional use or similar procedure to allow special exceptions where the intent of the ordinance would not be violated. He said that he did not think that a freeze on developments as proposed, would be justified. O. Hartman said he felt the Planning Commission' had enoughinforrnati'on to adopt. a Flood Plain Ordinance at this meeting. He stated hie preference for the approach taken by the County and suggested that the staff could be instructed to rewrite the proposed ordinance. Based upon the approach taken by the County. Whittaker suggested that the ordinanceK. 99 should be tabled to allow future time` for research and consideration. L. Hartman said if We are going to adopt an ordinance substantially similar to what has been presented, that the Planning Commission may as well carry out that action tonight. lie Nicoli expressed concern about an earlier remark made 1 • by the City Attorney that the City could retain a consulting engineer to review submitted development proposals for the flood plain. He said that if the developer were charged a fee for would in effect be pa paying for the cost of g the review, thathe P r 9 engineering ' services twice; one when he had the original plan prepared and twice when the city had reviewed the developer' s proposal. N. Chairman Whittaker asked the Planning Commissioners if theyfelt the staff should be instructed to do more accordingwork on the previous discussion ordinance TheconcensusWas that the ordinance should be sent back to staff for further work. O. Hartman moved to table the proposed flood plain ordinance to allow the staff further time to prepare the ordinance and to include the approach employed ►nthose the Washington Countyr Ordinance. Mickelson seconded and the motion passed by: unanimous vote of those Commissioners present. B.

By allowing continued filling, and the potentialplain development, for flood .,• , the City is creating a hazardous situation. It "�s now completely , •' legal; to fill or construct structure within the flood plain. This could include the construction{ of residential as well as commercial and industrial property, ; * an example being a in Tualatin. the recently flooded "Farmhouse Apartments" n and filling obstruct the flow of flood Both constructa.ra ,.' waters end also diminish the volume of water storage capacity within the flood plain. Construction and filling of the flood plain is an especially critical concern for a number of reasons. The Fenno Creek drainage area is currently developing et a rapid rate and is anticipated to grow even faster upon completion of the Durham Sewerage Treatment plant. This Urban growth end its related paving and roof structures decreases water retention on the ground and speeds normal storm drainage/ h " periodof •• increasing the - and filling is occur ` g storm runoff volume over a given time. At the same time development iocring along the rivers and streams , within the TigardCommunity, providing less volume and space for water storage and flow. The situation can be summed up as having an increasing storm water volume and decreasing storage capacity for this increased volume consequently a potential exits for floods of increasing seriousness. A given volume of water in a container of steadily decreasing size will rise over the top of the container. A similar situation is now ocouring in Tigard. Numerous .) s instances of filing flood plain areas have boon occuring within the City and are described as follows Crow Warehouse - Ash Ave and Burnham Street Oregon Food Service - Hall Blvd. southeast of Burnham Street. Ouvale Property - Hall Blvd. south of Burnham Street Atlas Steel Co. - Tigard St. , west of Main St. Dray Warehouse - "i igard St. , west of Grant St. Tigard Lumber - Pacific Highway, south of Johnson st Puget Ole Casting - unita Road, west of 72nd Ave. nine-hart Property - Shady Lane, at 95th Ave. A - Roy West, Main Street 61u th or Burnham Street Mv, yy •,.,:• .•.•, ... fib" .ay.w.yanw:l+a.nr.X . .r.. ..vs.�Iw. •+'+c✓ .Yawaw. J xua.., .T'hyyf .f.�I YVMW{'t.\,M_�K��AP/SMp, Bonita Plaza Apartments - Bonita Road at 76th Street Philadelphia Square Apartments -- Ash Avenue at Hill St. The Planning Staff is also aware of proposals to fill the following additional flood plain lands: Philadelphia Square Apt. Cxpansaon- Ash Ave at Hill St. Lee Property - Burnham Street between Ash and [lain St. Street. . , Johnson Property Tigard Street at Grant Filling can not only decrease the water storage capacity of the flood plain area, but also creates an obstruction to the flow of water within the Mood plain causing water velocity' to slow and sometimes causing erosion on adjacent stream banks. In some instances fills on buth sides of a stream can create a damming effect, increasing water depths on upstream properties. s Public roads, bridges and utility crossings can also adversely affect flood water flows. Often bridge openings constrict the flow of flood waters, creating an impoundment situation. The bridge and culvert on Hall Blvd. south of Burnham Street are currently inadequate to carry peakrun at Main flood orf as evidenced by last y bridge Street years flooding. The bx `�d also backed up water during last seasons flooding. (See Tale A for related data) A situation exists at the County bridge on Bonita Road where a downstream fill et Pudget Cconstricts channel to a greater Die Casting actually the charm degree than the existing bridge structure. At this point, given available data, it is difficult to predict the magnitude of the existing situation in terms of hazard to the public. We do know that, in similar situations concerning rapidly developing urban areas, flood water levels increase as development and filling occurs within givendrainage area. We can reasonablyexpect . t , than a flood danger and damage to increase if development and filling are allowed to continue uncontrolled. Consequently, the , proposed Interim Flood Plain Ordinance is designed to allow maintenance r f the flood plain as it exists, while a detailed engineering and environmental study is conducted to determine the magnitude of the situation and to suggest a method of managing the City's flood plain areas. 1 ;. 1 TENT_ or ROPOS D ORDINANCE As previously stated, the proposed Ordinance will allow maintenance of the existing situation within the flood plain, maintaining flood capacities and Plows storage cap and restricting developmentprone td flood damage.ga» The Ordinance is an ); �nter� interim m ordinance, proposed to be effective for a period of two years while the aforementioned engineering and environmental studies are completed.

"Policy and Standard 2 of the Plan states that it is desireable to "preserve natural drainage- ways by prohibiting development that would obstruct the flood plain, as provided by the zoning regulations. The flood plain of the Tualatin River and Fanno Creek have been delineated by the U.S. Army Corps of Engineers. " Although the Ti. nr.d Cnrnmun3,t Clan was adopted in 1971 and recognized the potential flood hazaad, this is the Cityts first attempt to implement a flood plain ordinance. Another subsidiary purpose for the adoption of a flood plain ordinance is the ability of business interests and homeowners in flood hazard areas of the City to continue their eligibility fear federal mart a e g 9 guarantees and insurance, mortgage loans, sand otherlending bconstructionfederally insured or regulated finance institutions for puroosas and other forms of federal assistance for financing capital costs of construction and equipment. The "flood Disaster Protection Act of 1973" provided the Department of Housing and Urban Development must identify flood prone communities and notify their executive officers by July 1974. Tigard has been preliminarily identified as such a community and had until January 1, 1975 to prove we are not flood-prone or can prove the existence of a local building permit system protecting againstflood hazards. The previously mentioned reva.ousl sanctions become effective July 1, 1974, faflood prone community cannot prove itisytflood prone and does not adopt ordinances satisfactory to protect developments within flood hazard areas. Adoptionof codes protecting against flooding will allow City businesses and homeowners to qualify for federally insured loans and federally subsidized flood insurance In addition to the above stated purposes for adopting a • flood plainWashington County has had a flood-plain ordinance ordinance for a number of years and has recently expended the extent of the ordinance to all tributaries within the county.

The reasons should be readily understood. If Tigard allows construction within the flood-plain of Fano and its tributaries, the, purpose of regulation set forth by the county government may be negated. Continuous ' regulation along all portions of ranno is needed to insure uniformity of control with the publicinterest as the goal. AREA OF APPLICATION The proposed FP District is intended to encompass those lands within the 1U0 year flood level. This level is recognized by HUD as a criterea for defining flood hazard areas and is a general definition of flood plain areas throughout the oountry., However, some communities have adopted SQ or 25 year flood levels. Tho 100f ' year flood is defined as a 1% chance of a flood occuring within a specific area within any particular year. The proposed base for determining the 100 year flood level • within the Tigard Community is a map prepared by Washington County in conjunction with several Federal agencies. The map is an aerial photograph depicting the 100 year flood plain and also indicating elevations of the 100 year flood at various points along the Tualatin River and Fenno Creek. Measurements from this map and use of elevation interpolution , on the Ciyyrsnow Phmetrimaps will be used to define the flood plainn areas on speoific properties. PERMITTED USES. . Y' Permitted and prohibited land uses are defined by thero osed ordinance P P 0a,aically, no fill or structures are allowed within the flood plain. Temporary structures, easily remuvable duringaerios of flooding, wouldb , allowed. Structures associated with recreation development, not significantly impeding the flow of water within the flood-plain shall also be allowed. Off-street parking and r maneuvering areas for all uses are allowed as well as landscaped areas and yards in residential zones. Non-conforming uses located within the FP District ere intended to be handled as non-conforming uses aro currently sse processed.cti, od. That is, they may increase floor areas by processed. approval by the Planning Commission at a public hearing. SPECIAL REVIEW This section of the proposed Ordinance allows any property owner, who has cause to dispute the City interpretation of the regulatory flood' boundary upon his property, to apply !^ Page cy to the Planning Commission for Special Review. The Planning Commission, at such a review, would determine if the appeal n of the regulatory flood boundary is valid and, if valid, '.would act to accept a modified flood boundary on the applicant's property. Of course, an appeal to the Council is possible if the Planning Commission rejects an applicant' s request. This provision of the Ordinance is designed to allow the property owner an administrative recourse if the City staff should interpret the regulatory flood to the perceived detriment of any flood, plain property owner., CONCLUSION In summary, there is a community need to restrict development end filling within the flood plain areas of the City in order to maintain the existing level of flood hazard t:and enablitig the City to formulate a detailed management plan of the flood plain. The proposed Interim Mood' Plain Ordinance P will allow the City to maintain the existing flood situation for two years, while developing data enabling the City to delineate the single flood-plain district into various ' components each exhibiting varying degrees of sansi , 'vi#ty to. developments ror instance, the flood plaint ea,,, we broken down into the floodway, the flood fringe and the flood' plain es distinct areas. Also proposed is to study and gather data concerning the grade of the stream, runoff characteristics and to identify environmentally sensitive conditions which will merit special consideration in the planning process. The interim status of this emergency ordinance is the means by which the City can borrow time to complete technical studies while decreasing the adverse effects on stream flow caused by development. It is hoped that s , proposed or modified ordinance may be adopted to protect the public interest and enable the ...., i City to accomplish a long-term management program for ite flood plain areas.

Mr. O'Mara who •lives on O'Mara Street and owns property • - on ranno Creek spoke oke to the need for a Flood Plen • Ordinance and especially for the proposed engineering study. { C. Bill McMonagle of Harris—Mc(lohage Engineersineers asked if the affects-of the dams on the Tualatin would affect flooding in the Fenno Basin. O. Nicoli said that he has spoken to an engineer familia projects Tualatin and he stated with. the dam ro acts oh the �`� that they would have little affect upon flooding in the ranno Basin. L4 Hansen said he recognized the need nor a I"lood plain Ordinance, but stated his objection to voting a total moratorium in the flood plain for a two year period. •. II E.

Q. ,„ THE FLOOD DISASTER PROTECTION ACT OF 1973 On December 31, 1973 President Nixon signed into law the Flood Disaster Protec- tion Act of 1973 (P.L. 93-234). This legislation significantly expands the avail- ability of insurance protection from floods, It will also lead an estimated 10,000 to 12000 flood-prone communities to control development in flood hazard '',",•c.,`'[c,'":,4,, areas through land use measures or be faced with the loss of various types of federal assistance within these areas. . BACKGROUND ' A''''''-' The flood insurance program, administered since 1968 by HUD's Federal Insurance Administration0 allowed property owners in flood-prone communities that carried out flood mitigation measures ( i .e., land use controls) to purchase federally- subsidized flood insurance. This insurance is sold by private agents at rates J,I.rs, subsidized 90 percent by the federal government, The 1968 legislation, which originally set up this program, provided that Insur- ance could be made available only after detailed studies had been made to esfab- lish actuarially sound rates for coverage and to determine levels at which new Construction would be reasonably safe from flooding. The definition of "reason- ably safe" level for any particular area Is the 100-year flood level , or a 1 per- cent risk of flood in any given year. Because this requirement severely restricted the number of communities able to ,44'... qualify, the Congress In 1969 enacted an emergency program that allowed insurance .„.::. to be made available to existing structures as soon as a community agreed to take general steps to reduce flood losses on new construction. This allwed 2,263 communities to enter the program, for a current total of 2,855 communities now participating. DETAILS OF THE FLOOD DISASTER PROTECTION ACT OF 1973 Incentives foLrIntlnity_Er±1.5.12tio . HUD must identify flood-prone communities , , ______ and notify their chief executive officers by July, 1974, These communities have until January 1 , 19750 to prove they are not flood prone or to apply for partici ,,,i potion, which includes proof of the existence of a local building permit system ,„4 protecting against flood hazards, Effective July 1 , 1975, federal mortgage guarantees and insurance, mortgage loans, and other lending by federally-insured or regulated finance institutions for con- struction purposes and other forms of federal assistance for financing capitol costs of construction and equipment, will not be available to businesses and In dividuals In identified flood hazard areas unless the community has qualified for the program by adopting federally-determined land use controls, (Notet "flood hazard areas" are within, flood-prone communities), „Incentives for Individual earticipation,, Upon enactment, individuals and businesses , 4 In flood hazard areas in participating communities would be required to purchase flood insurance In order to be eligible for federal mortgage Insurance or guarantees, borrowing frm federally-Insured or regulated financial institutions for construction purposes and receiving other forms of federal assistance for capital flhOhCItigi In, n , such Communities) moreover) flood insurance, If available, must be purchased as a ',..„i, condition of federal disaster assistance for construction or reconstruction, )14.

Subsidized rates will be available for all construction begun before December 31, 1974, or the date when the detailed rate and elevation studies are completed, which- ever is later. For all construction begun in flood hazard areas after such date, ,..4.'. the full actuarial rate, often five to ten times as high, will be charged. Because the actuarial rate takes risk into consideration, new construction conforming to improved land use, zoning and construction methods may be eligible for this un- subsidized insurance at lower rates. The basic subsidized chargeable rates for flood insurance on single-family resi- dential structures are 25 cents per $100 of coverage; thus a home owner with a structure valued at $20,000 would be able to buy flood insurance protection for about $50. Full coverage for homes valued above $350000, however, will necessitate ,......,,.: the purchase of unsubsidized insurance. (Note: Full coverage is necessary for structures in flood hazard areas as a precondition of eligibility for federally- financed assistance). Consultation with Local Officials. One of the primary stumbling blocks to passage of the legislation earlier in 1973 was concern that HUD would not adequately consult with local officials in carrying out the provisions of the act. Therefore, the law contains a provision requiring the secretary of HUD to "establish procedures assur- ing adequate consultation with the appropriate elected officials of general purpose • „ local governments." The identification of flood-prone areas and the application of land management criteria are areas generally subject to such consultation. Local officials must specifically be informed of the purpose and details of any flood elevation studies so that individuals in the community may have an opportunity to present their own data and facts. • AOPeals. The HUD secretary must also adequately publicize projected flood eleva- tions for land use purposes by publication for comment in the Federal Register,„ by direct notification to the chief executive officer of the community and by publi- ' cation in a prominent local newspaper, Publication of flood elevation determinations In a local newspaper must occur twice 4. during the ten-day period following notification to the local government. Property owners have 90 days during which to appeal these determinations to the local govern- merit on scientific or technical grounds, The local government must consolidate all such appeals and issue a written opinion stating "whether the evidence presented 1ufficient to justify an appeal on behalf of such persons by the community in 1ts 5 .8 own name, t I In every case$ individual appeals mus - 1 be forwarded immediately to (SJ HUD by the community, • v CA',1 Communities have ;.:the same 90-day period as do individual property owners to appeal rt .. it , to HUD. The secretary must resolve such appeals by consultation with officials of the local government involved, by administrative hearing, or by submission of the conflicting data to on independent scientific body or appropriate federal agency for advIe." Communities have 60 days after the socrefaryfs final deter , mination to appeal to U.S. district court.

A city may also apply ,t:./,', for participation in the program prior to recei',ing the boundary map, Within six to ten working days of _,,,' receipt by HUD of an application for participation in the program, a city becomes eligible for the sale of '4' 7', flood insurance and local citizens ma. agents, ,xt y purchase such insurai.ce from local insurance ��s ;i Ana pea appeal should be directed to the Secretary of HUD who has a number of alternatives in responding to y it.

"`Resolution 13-1" commits the city to applications to assure that sites will be reasonably safe from flooding later "w,,, when they receive a more detailed topographical rim of the flood plain from H safe 3 ,r map p UD,most cities will have to amend existing ordinances to control development in flood-hazard areas and in some cases, require floodproofingi Initially, however, the adoption of a building permit process and the two resolutions are all '�; that is required. 3 ' After HUD approves a citys application, subs becomes available for existing 1. subsidized flood insurance be ')i structures and new construction within flood-hazard areas regardless of their location.

Individuals residing '( in flood-hazard areas would be unable to secure mortgages or loans from the VITA or FHA. Following a city's application to and acceptance in the flood insurance "emergency program",HUD will ' contract with the Corps of Engineers, another federal agency or a private firm to make a more thorough study of the city's flood hazards. The typical ypicdl flood insurance study (which results in the issuance of 'xF topographical rate maps) includes (1) a profile of water surface elevation for 10, 25, 100 and 500 year floods; (2) a map showing the boundaries of flood insurance zones and subzones and base flood (100 year) ' elevation lanes; (3) flood-hazard factors for each zone and subzone; and (4) floodway data for streams and • •.c high hazard areas in coastal area areave Costs of the study are borne by HUD, CI ,, Before HUD can undertake such a flood insurance study in any community, the 1973'Act requires HUD ,} ft,re to designate a local coordinator who will consult with local officials and the contractor performing the ; study. When the study is completed,it is sent to HUD for review, The findings include designation of flood Y r elevation levels which in turn. may necessitate-local ordinances setting standards for construction and floodproofingi Local officials receive a copy of the study and HUD's findings based upon it. HUD is also required to publish its findings twice within a ten-day period in a local newspaper which will reach residents of the community. The city, or any citizen or group of citizens,then has 90 days to review HUD's findings and appeal them, Such appeals must be based upon technical information. If a city (or group of citizens) 'f disagrees with the determination which HUD makes on the appeal, it still has 60 days to take its case to the United States District Court of Appeals which has jurisdiction in the area. • ti When insurance rate maps are finally accepted and approved, the city enters the "regular" flood insurance program which doubles the amount of coverage available to individuals living within flood-hazard , I�i� g . ; prior : program, _ areas, For a single family residential home constructed riot to the city's entering the regular the e . amount of insurance increases from $35,000 to $70,,000.The first $35,000 continues to be subsidized (as it t a`� was under the emergency program) while the second $35,000 is available at actuarial rates, Buildings or ' r sidences constructed in the flood-hazard area after the rate map is adopted must pay actuarial rates for both first and second layer coverage, Once a community is enrolled in the regular programs emphasis is placed upon floodproofirig new structures within flood-hazard areas. If new buildings are constructed properly,the actuarial rates for flood. insurance will approximate the subsidized rates, "Proper" construction of a residential building requires that the lowest habitable floor in a residence be above the 100-year flood level Non-residential buildings must be built out of the floodway or floodproofed. Other measures aimed at mitigating flood damage o i i.....g u .. 1gi p Y'. i would include anchoring buildings to prevent their movement or collapse, using flood resistant materials for construction, regulating subdivisions and new developments to assure adequate p q provision of drainage, eliminating or minimizing infiltration in water or sewer systems, and designing waste disposal systems to resist flood damage. dam a e i F1oo dproofing, improvements, modifications and condemnations are not required for already head y existing structures located within flood-hazard areas, In fact, structures which already existed or were started prior to the completion of insurance rate maps are not required to have insurance at all unless or until there is a transaction involving a sale or alteration of the existing mortgage, PURTIIER INFORMATION G'' Further information about the flood insurance program and the Plood Disaster Protection Act of 1973 is available from Chuck.Steele, Flood Insurance Specialist,HUD, 520 S.W. 6th Avenue, 2nd Flood,Portland, Oregon 97204 (phone: 221.2608), The Federal Insurance Administration publishes a monthly list of . communities which have become eligible for the flood insurance program,To get on this mailing list, write to the PIA, 451 7th Street, S.W.,Washington,D,C, 20410, Cities desiring technical flood plain information 1{i should contact Robert Evans, Flood Plain 1Vlatiagement Specialist, Oregon Water Resources Board, 1158 ° n 1158: Cherimeketa Street, i ,E,, Salem,Oregon 97310(phone: 37813671), d,J•. ,n'ti. , n a, 'sui .„ 1.,�.t sv•i. .:. ,+s" -,e ro ._;.._, i w 1.'Ye IIWI= ___ ..;- +1:....... -....., - - .. .. .. . ,. kryryilMr+wn.yir. .,.+ 1', r"aat:.'Y r+V yt w..�ww>rt- w..ry:.•+r?rN..ww M ,rWw...«o-...:„xrr!.r ,.+«r+wwwr...;,.+..w.,:.,.^,....:...-�w-..+^.r„:nr^d-...^...c•?,,.,«...,w^—•v u w-r:wr. ,wy.r'.+.slt .wznam�www.rrrsrrv.a�;ra,..i-+ ..+ y.unw� Ottk0,11.

Use in Flood Hazard Areas The Tig ard, Commune. •ty Plan indicates the 100-year flood plain along I', the Tualatin purpose tin River and, Fanno. Creek. The ur ose of identifying the flood plain is to prevent loss of life and property from flooding, qualify existing development for subsidized flood in- , surance and s preserve the natural greenway along these streams, In order to implement this aspect of the Tigard Community Plan, the Tigard zoning and subdivision ordinances must be amended. Attached are examples of subdivision and zoning provisions that can be used in preparing amendments to Tigard's existing ordi- nances. In the subdivision regulations that are attached, the flood hazard provisions are integrated With the normal provisions of the ordinance, The attached coning ordinance describes provi- sions for three different flood hazard districts, Of these dis-- "tricts the "Flood Regulatory District" has the most direct applica- tion to the regulatory needs of the Tigard area. The Corps of to gineers has "Flood g prepared a report titled Plain znforrriation, Tualatin River and Tributaries, Washington County, Oregon, " June 1969, which provides the engineering data needed to establish flood hazard district boundaries° y 1■VES e" iMiEfAVrIEip .:. ,ry ,:Y e ,,DRAFT SUBDIVISION INANC) 5-420 :.. 79 920, , OUTLINE AND TEXT OUTLINE ' Page 1.

SECTION 6,0 PROCEDURE" FOR PLAT APPROVAL The procedure for review and approval of a subdivision plat consists of two separate stops. The initial step is the Prep- aration and submission of a preliminary sketch plat of the pro- posed subdivision , The second step is the preparation and sub-- mission of a final prat together with required certificates. This final plat becomes the instrument to be recorded in the ' office of the County Register when duly signed by the Secretary of the The subdivider should consult early (review agency) and informally with the and its technical staff (review agency) for advice and assistance before tepreparation of the p relimnarY... sketch plat and its formal application for approval. This will enable him to become thoroughly familiar With these standards and procOdures.

C' SJ 4. ---- ---~-=-- --- --- --- - ---` ---- ~\ • For many communities, correct flood-plain use is among the principal land-use planning and management goals. Often, as in the case of Tigard, flood plains constitute a consider- able portior) of the undeveloped lands. If improperly used, .0) they often become problem lands Oue to blighting of flood- damaged structures and public expense for relief and repair of flood-damaged developments. ft r Within the City of Tigard flows Fanno Cre,lk, a tributary to the Tualatin River to the south of Tigard, and many smaller tributaries to Fenno. These tributnries take the form of shallow ditches or small, intermittently flowing creeks which swell and overflow their banks during times of peak rainfall. This system of small tributaries, Fenno Creek, and the Tualatin are integral parts of a drainage system wt' ich must be considered for flood-plain management. If flood-prone lands are left open, practically no flood losses occur. nut those flood-prone lands tAra attractive Per a wide range of uses because of their loci,lbional advantoges. Flood-plain management must have as its principal objective the allocation of land to its moot appropriate use f'rom the viewpoint of the community as a whole, Several specific ,-,i„ objectives relate to minimization of flood damages by attempting tot p 4 n It'hA ,41;,1,:', 1 k 4. t ft%, ' ' VI * / N J"�t lFc,, yl ° Protect adjacent, upstream, and downstream private i s „,. and public landowners from direct and substantial x,, ,p. `,,`,,' increases in flood damages.

J.''' xwiy a Deduce risks to the individual or his family or guests §, , s,°;r Jr from threats to health and safety or, economic loss. „FF Yt, ,, The principal tool for the realization of these objectives 4' 4+4 is the food-plain zoning ordinance. Other, methods include Ol. ,�:, � the use of subdivision, building, health, and other ordiances rr, ,r , '” intended to protect people and property in the flood plain. Fy+' "4*A� The flood plain zone is more often established as it allows `'� a continuous area to be controlled as compared to the patchwork 1t4r„ effect of other ordinances. J, ' Washington County has had a flood-plain ordinance for a number ,,x� of years and has recently expanded the extent of the ordinance t P, i `w''' F to include all tributaries within the county. Of importance 1';"4' at this point is to understand that while Tigard has no flood- n ,-,:', plain management program, Washington County has developed ! a system encompassing all waterways within the county, a,' including the portions of Fanno. Creek under county jurisdiction. i ram+w t su• +aA t nl !¢. A, ..e' .1,A.rn.,6 1 y,�Jr i''.` n:+.'"*+^M�!Y 4's.h,M"A"Y :!.1 Y I b'cB�.0 T'!t ix,Y}f `S rW. ,W�.� r/ M.J i 1 rt pb:•, ..CA^pt,,..

The in�ent of the Tigard ordinance establishing the N,{Jtf. Flood plain... District is to provide the city with a regulatory ,.r"' document to be used on an interim basis for a period of two years from the date of acceptance. At the end of this period it is t s proposed' that dame will be available which will enable the City to delineate the single flood-plain district into various components each exhibiting varying degree of sensitivity 0; to development. FO:r instance, the flood plan can be broken y down into the floodway, the flood fringe and the flood, plain as distinct areas. Also proposed is to study and gather data f . concerning the grade or the stream, runoff chaacterist,i ca and to identify environmentally sensitive conditions which will r� �" merit special consideration in the planning process.
