Dick Kangas testifiod for the applicant and accepted the�mmended condirions of �$` approval. He argued the sign saze is needed to make it legible to drivers on 72nd - �v��f ,,�� Avenue,because of the natur�of tl�activity(i.�.,a commencial activity in an area of �, indnstrial uses)and ba:ausa of the tc�pographic and road alignment cons�raints in the '�'` �_ vacinity,particularly foP southbound tra�°ic.

EVALUATION OF REQUEST A. Sign ex�ept��n. 1. The size of the proposed sign is within 25°l0 of the permitted sign size. £; � 2. T'he sign size will not cieter�'rom the purposes of the sign chapter,becaus�or�e�,f t' us the purposes of the chapter is to avoid sign clutter and the proliferarion of signs. By 'i� combining messages for two businesses on one sign,the appfi�ant reduces the number �� ,� of signs necessary ta identify thosc businesses. Also,assurning each business had its w� own 70 square foot sign,a tatal of 140 square feet of signage could be providcd for the �� two businesses, By advertising both busincsses with only 87.5 square feet of sign,the x� applicant avoids having signage that might otherwise be buil� This fulfills the �� parposes of the chapter. � �� ;fi 3.The sign size pmposed is necessary to make sign sufficiendy legible,particulazly for �. southbound drivers,because the topography to t,he north obstructs views of the sign; � because the businesses are set back from the street and not clearly visible from the � street;because 72nd Av�nue makes a sharp twm at the entry to the site,further � clisteacting drivers'attemdon;and because most other nsers in the area are Yndustrial and attract drivers who ane mare familiar with the site from repeated�risits,whereas the Power R�nts use is conunercial and is used by the general public many of whom have not been there before. 4. Condidons are warranted to require the applicant to reYnove ithe sign at the applicant's cost when necessary for the City to undertake warlc zn the right of way. B. Sigra uariance. 1. 'd'he proposed variance,allowing the sign in the�ght of way,will not be materially j: detric�ental t�the purposes of the Code,because the proposed sign location dc?es not obstruct visibility or lead to clutter along the right of way. 'Th�narrow diameter of the ;; sign gost and its elevation above the ground minimizes the intrusion of the sign in the � right af wa}�. The locadon of the sign identifies th�sub,j�ct business better than would ,; ; a sigr�ent�rely�n private property,because an on-si�e sigri would nat be visible for t€ southbound tra€fic and would have W be much larger to be visible for northbound ,.,� traffic. The Code ptomotes visibility of bUSinesses. :';� 2. The�lag lot design of the site,topography,and street alignment are special � - circumstances that apply to the site that do not apply to other pr�operties in the district. �� The lot design and street alignment dictate that the street frontage be used entirely for �� access;a sign in the flag pole portion of the lot would be an obstacle to traffic.

Section 18.114.].45 (A)(�) of Tigard's Community Development Code contains the criteria whereby the Hearing� Officer ehall approve, apprave with conditione ar deny an application for a Sign Code Exception. This code section states: 1) Up to an addi.tional 25 percent of sign area or height may be permftted when it is determined that the increaee will not deter from the purpose of �his chapter. Thie increase ahould b� judged � according to sp�ci.fic needs and circumetaa�ces whieh neceeeitate additional area to make the aign sufficiently l�gible.

Specifically, staff feele that � although approval of this Sign Code Exception would permit the inetallation of a sign which is 25 percent larger than that which the code i� ' norntally allaw�, the applicant has propoaed the combining of two ;� freeetanding signs (Power Rente and Finlandia Saunae) anto one �,� freestandinq sign structure. Thia results in a aign with a total sign �� FE area ot 175 aquare feet; which ia a 37.5 percent reduction in the 280 i:s aquare feet of sign axea which may otherwiee be approved should each ?;� respective bueiness appl.y for ite' own freestanding sign. Therefore, th@ �1 approval nf this Sign Cnde Exception would not produce the effect of a Y� ;=z "proliferation of eigns'° or add to "sign clutter" as referred to by the s� etated purpose of this chapter. `i,� � SIGN CODE VARIANCE FOR SIGN PLAC�MENT IN THE PiTBLIC RIGHT-OF-WAY � � Ccsde Section 18.114.070 (L) �tates that no aign� ahall be located in the � public right-of-way in whole or in part, except for signs legally erected �} for informational purpoaes by or on behalf of a government agency. �� Cnd� Section 18.134.050 (A) lists the critezia necessary for the approval 's .. of a Vari�nce. The criteria are epecifi�d as follows: �"� ' ;�:;j 1) The proposed varianc� will not be materially detrimental to the ;;� � purposes of �hie title, be in conflict with th� poliaies of the ��! comprehensive plan, to any other applicable policies and atandards, `'� and to other properties in the same zoning district or vicinity; 2) There are speaial circumstances that �xist which are peculiar to the �� lot size or shape, topography or other circumstances over vahich �he ''} ;;�fi applicant hae no control, and �hich are not applicable to otherc ; properties in �he same zoning district; ;:,:� as 3) The uee propoeed will be the eam� as permitted under this title and =�� City atandards wil�. be maintained ta �he greatest ext�nt that ie ;i reasonable pogeible while permitting eome economic uae of the land; � 4) Existing physical and natural systems, auch as but not limited to � traffic, drainage, dramatic land foraie, or parka will not be � adversely affected any more than would occur if the development were ,� located as specified in the title; and 5) 'The hardship is not aelf-imposed and the variance requested ia the � minimum variance whi,ch would alleviate the hardehip. � STAFF ANALYSIS OF SIGN CODE VARIANCE 1) The purpose af this code is to reduce the amount o£ sign area and numbers af signs within the City limits in order to provide for an �esthetically pleasing environment. Although the applicant ia regueating a�dditional eign area above that which ie normally permitted by tti.�s code, i:his proposal is coneistent with the intent of the Code because the total number of signe and the total sign area being proposed at thie location are both significantly less f than that which could be approved �houl.d Power Rents and Finlandia ; &aunas each cYsoose to construct �eparat� f.reestanding eigne. i Additionally, the pla��ment of this sign shall not in�erfere witl� � STAFF REPOI�T - 3CE 91-0003 SCFIIMMEL/SI.P►ZE SIGNS PAGE 4 �r � �� ''?� �`� �;�: A ` ,��'.uu..>,��r:a....�1...:4,�.:.,�n.i,._ .r ...„s, n.,.. ..,.,...av+s.L�,..n4.l...ts.. ...._w.f.Lu�,..�ti...,zL ...+."u . �T� F '..... !.�.� ^f , .,_ , � `vSe_��.:'�[}...i.11.)�'U�..�r.,..

SubsequentlY. plaCement of the aign onsite is li.mited at b�at. Traveling south to north, SW 72nd Avenue turns in a northweaterly � direction and begins to climb a �izable hill. Staff contencls tha� the combination of both the curve and elevation of SW 72nd Avenue �nd �pecific site characterietics preclude the reasonable placement �� ; of a freestanding sign on ths property itself.

Existing uses and structures : There is a dweUing and separate garage on the site. T'here is vehicular access from the site to 79th Avenue. D. Propased uses and structures: l. The applicamt proposes to divide the site into four lots of 9,403 to 9,446 square feet. Two lots would front on 5W 79th Avenue,argd two lots would front on SW 80th Avenue. All lots have an average width of at least 66 feet and an average depth of at least 140 feet. Single family deeached dwellings will be built on the proposed lots after the existing structures are demolished. �, 2o Access will be provided to the two westerly lots by means of separate driv€s onto 80th Avenue. Access wi11 be prnvided t4 che tw�easterly l�ts frorn a common driveway to be situated on the propased southeasterly lot; however,if the applicant impraves sight distance alung SW 79th Avenue,the common drive could be moved to the common property line between the n�artheasterly and southeasterly lot or separate access drives to 79th Aven�ue could be approved. If adequate sight distance cannot be pmvided consistent vaxth C:ity Code,then the proposed northeasterly and southeasterly lots will be combined and only lot v�ill fmnt SW 79th Avenue. See also finding II.I. E. Existing and proposed vegetation: �� The site contains dense mature vegetation,including substandal deciduous and c�nifer trees. The applicant did not provide a tre�inventory an�l did not describe or justify the need t� cut ar substantially affect existang vegetadnn as a r�esult of the pro�osal. However,the Hearings Officer assumes some vegetarion includi�ng trees will be removed,consistent with applicable laws�d pursuant to duly issued permits,to provide space for structures, utilides,access, and yards. F. Topography and drainag�: �,; 1. The site slopes from a high point�f about 190 feet neaz the southeast boundary along SW 74th Ave�ue to�low point of about 170 feee near the nmrthwest boundary along proposed SW 8(hh Avenue. A knoll exists at the eastern boundary of the site vvhich impedes sight distance along S�V 79th Avenue. 2. The applicant proposes to cut and�ill as shown on page 3 of the prelimanary plat to midgate the sight distance impediment or to otherwise achieve adequate sight distance by situating a cnmmon drive�.t the peak of the knoll. A portion of the frontage of the lot south of the site along SW 79th Avenue also will was proposed to tse regradecl to irnprove sight distance and moderate grades. 3. The applicant submitted a preliminary storm drainage plan. It provides that storm water from the two westerly lots will lbe directed onto 80th Avenue. Storm water from tt�e easterly lots will be directed to a storrn sewer easernent across the north edge of the northeasterly lo�:. The agplican�t will improve a 10-foot vvid�rig rap swale along the north edge of the two northerly lots. The applicant will discharge storm water f.rom 8Qth Avenue into the swale. Storm water will flow east tlarough�ae new swale, ; northeast through an exisdng broad swale across an intervening pri�rate property �;Y; (Skoyar),through a neev culvert the applicant will install under SW 79th Avenue, and � east acrc,ss other private garoperties (�Iawley and Marciene In to Fanno Creek. ;; �< +�� ;.Y r��' Page 2 - Hearings Officer decision Ss SU�9d-(KlU7(Raze tbfeadows!I!) �s ��,i . r..-. .�.,,,..,...-_. ... _ ,.. ...-: �,,:.?.: -� nrn. �-� -� ..�...,.--,.�,F-.,;,.-•:�-r� ;..,., � :- � .4a ��- - ... _ _ . � � � � � � r .i ti7_ 3 � F`. � +' � Y., a � ; ti �. r �.,..,�_...G„ � .. . � .�...o,. _..x�._ _ ...r. ..1..,:;(r �..�,_U.��...»�.,�». .._;�,..�.... _._.,.,,.<,. .��.,_t.^r�>ur.,,�Mtz: .�,r.u..,_,..w t.._�...,.w � �:F:�...., i.,,'...,�.u.....1.. _, ,�..,�..i.._»..�ii._. .�,...,....�..., . � � 4. City staff have reviewed the preliminary plans and calculations,and concluded the propc>sed systern will have adequate capacity to accornmadate storm water,althongh grading around the 80th Avenue outfall and along the rip rapped swale may be needed to prevent starm water froYn flowing onto yards on the site. G. Plara designation and zoning : The site and vicinity are designated Low Density Residential on the Comprehensive Plan Map and are�oned R-4.5(Residential). H. Public services a�d utilities: The applicant proposes ta connect to extensions of exisdng sanitary sewer and water lines to the west. I, Streets and access: t 1. The site has about 13B feet of frontage on both SW 79th and propased S'W 80th Avenues. SW 79th Avenue is a minmr eoll�ctor street with a rougtrly lU-foot wide half- width paved secsion in a 20-foot half-width right of way with a 25 mph speed limi� � The road is in poor condidon and subject to sight distance constraints due to the knoll along the site's southeast b�undary. Substantial on-and off-site�ng would be necessary to conform 39th Avenue to the City gcade and site distance standards fur a minor eollector street,as shown on Sheet 3 of 3 aceompanying the application. � Somewhat less gra�g on-and off-site raaay rernedy the sight distance problem from one driveway on the site. 2. SW 80th Avenue will be partially built as a condido�n of approval of SUB 9t)-0007 (Raze Meadows I and lf�. The final plat for that su}xl�vision has not been approv�ci and SW 80th Avenue adjoining the site has not baen accepted as a publia right of way yet. ' Therefore,�t this time,that stm�e dces not exist. 3. The applicant groposes to dedicate an additional l�feet of right of way ad.join'vng the �' east and west sides of the site for future strect widening. The applicant propases to improvc SW 80th Avenue to full width local street standards which will requu�e dedication of right of way and construction of stneet,gutter,curb,sidewallc and utilities along the west boundary of the site. The applicant does not propose to unprove 79th Avenue except as necessary to accommodate sight distance and access to one or two driveways on the site. 4. There is access from 79th an.d 80th Avenues north eo Bonita Road,an east-west arterial stree� There will be access from 80th Adenue west via SW Viola to SW Hall Boulevard. However,there is a lack of east-west cross-str�ets in the area generally. J. Surrounding land uses: � � ' Surrounding land generally cmnsists of oversized parcels developed with single far�ily detached dwellings and associated accessory autbuildings.

FiEARING,TESTIMONY,AND NPO&AGENCY CQMINENTS A. Hearing. The examiner received testimony at the public hearing about this application on May 29, 1991,and received addidonal written evidence during the p�rri�ci while the record �� rera�ained open until June 27. A record of that tesdmony is included.herein as Exhibit A (Parties of Record),Exhibit B (Taped Proceedings),and.Exhibit C(Writ�en Testimony). These exhibits are filed at the Tigard City Ha11. B. Sum»iary of testirnonyo 1. Dick Bewersdorf testified for the City and samnx�ized the staff repoat and recommendatnun. Chris Davies,fi:om the Cit�,�Engiateering Department,testifieci about r�ads and drainage. He discussed concerns about achieving the 250-foot sight distance �' ' required fcx lots 2 and 4 along SW 7'�th Avenue. If the applicant built a common drivevc+ay for the two lots wholly on lot 4, 10 feet south from where 'vndicated on the proposal,th�250-foot sight distance could be aChieved. 2. Randy Klarna and JiYn Raze testified for the applican� Mr. Klarno introduced a written statement dated March 2S. He su�marized proposed grading for sight distance alang 79th Avenue,noting the adjoining prop�rty owner to the south has provicied a right of entry to facilitate grading that extends onto his pnoperty. He described efforts to meet with area pro�erty own�rs to discuss drainage plans. He opined that the , subdivision�will not result an an increase of storm water discharge from the property. I Mr.Klarno argued the property north of the site is hydric due ea storm water baek-up ' west ef 79th Avenue and the lack af a culvert under the street. The proposed culvert ' will end up drai�ing the property to the north rather than increasing drainage unpacts on that site. SV�r.Raze confirrned seiected testimony by Mir.Klarna 3. Sheldon Skolar and Williarn and Wendi Hawley with the follawing concerns: a. Drainage of storrn water discharge from the the site to the adjac�:�t north � �� pnoperty would create a creek. 44 i �f�i. � k Page 6- Hear+ings O,jJ`'rc�r dscision � SUB 91-0007(Razs Meadows I!I) �� ?: ur t - � �; r��i`. . . � . ... .., :___.��_ _ .�.. .___.._. . . . .. . . . ,i 1"r�; e.

Lac�C of plans for a culvert across SW 79th Avenue and failure of the City to regard the increased volume of storm water as a pmblern. Ms.Hawley testi�f"ied that at a meeting of NPO#5,Mr.Klarno predicted a 20 percent increase in the storm water dischazge from the site aitd had agreed to provide a culverk with a velocity , dissipator on the downhill side of SW 7yth Avenue. � � C. NPO and'Agency Comments. ;. 1. NPO#5 recomrnended tt�at proposal should not be approved until a new storm �; drainage plan which mirigates impacts to adjoining property is submitted. The peak � which impedes sight distance,mentioned in the following secaon, also creates a �.,�es±�?n hazard�d should be reduced to provide adeqaat�sight distance. r 2, 'i he City Engineering Division recommends the applicant be requ��d tc��irnit development to one parcer along SW 79th Avenue or to improve SW 79th A�enue to comply with minor collector sight distance standards. Thc Di�rision bases its comments on the lega125 mph speed limit and resulting 250-foot sight distiance requirernents and on the eacistence of a steep hill along th�eastern boundary of the site on SW 79th Avenue. 'The hill impecles sight distance and the proper�y may have to be graded or driveway reYocated to achieve sight distance for two lots. 'I'hey also recommend certain sewer extens�ons to serve the site. These extensions depend on complerion of sewer extensions in Raze Meadows I and II. 'I'hey also recommend the applicant be required to contribute a fee in lieu of build'ua$a storm water quality enhancement facility on the site,and that the applicant show that storm water from the site will not signif'�cantly affect downstream preperties. 3. 'The Fire District recommends provision of adequate fire hydrants coordinated and approv�d by the Water District Praposed lots 3&4 should not be allowed to be creattedd before a�ccess to SW 80th Avenue is created. The�Vater Di.strict notes that the $�inch water line on Slst Av�nue must be exrended by the developer to serve the propose€1 lots. 4.Tigard Sehool Dist!rict identitaed the s�hoals served by the property and noted its concern regarding groevth in the ar�a�enerally as it relates to school capacity. School cap�city is ex�ected to be exceedecl as a result of this and othcr cievelopments i�n the area,and core f�ilities are insufficient to use portable classr�oans< [However,Mr. Off'er noted the Distriat has applied to the CiYy for pernvts for more poa�table classmoms.] It�commends prospective purchasers be advised that students may have to be bused to other schools because of exceeded school capacity due w this and other developments. Other steps to address overcapa�ity may be taken by the District. 5. The City of Tigard Public Worlcs Division cammente,�i that�he e�cisring buildings will have to be removed to cons�uct the proposed saautary acid storm sewer in the propused easem.ent. A deed restricdon should be noted on the plat prohibidng building t on the eas�ment. f. The City of T'igard Building Division couunented that a building demolition permit must be abtained prior¢o remo�nng the exi$ting stivctures. In addition,if adequate lot slope exists to access either SW 79th Avenue and S�V�Oth Avenue,roof and pavernent draiu�s should be run to the public xight o�'way and to an apprnved public storcm drainage system, i��i�Yuuii��t.e�'t�':�rain as�v�il�ble,eaah a�ew buildin�will require an on-site disposal system approved by the plum�bing inspector.

Dear Greg: . • - Pursuant to your �equest, this lett€r x°eviews the c�rainage im� pacts tn property owners dowristream of the Raze Me�dows subdivi- sion. Specific comm�nts address the Scolar property, fihe I�awley property and the Marciene II Apartm�nt si.te. • In general, the bas3n in �ons�.deratian extends from approximately thP intersect3on of S�.W. Ross Street and S.W, Hall �lvd. to th� west side nf the Marciene II Apartment site near S .W. ?6th A�enue. The basin is appror,imat�ly 19 acres. Slopes a��era�e 2� to 5� longidutinally along the natux°al swal�. Raze M�adows sub- division is � �G acre development of which 305 acres a�re within the basin of coacern. Two and a half acres drains to a seperate basin. Tl�e Raze M�aciows subdivision develops approximafiely 20� of the basin. Desian Consideratic�n� Agencies typically require storm draYn systems to be designed for � either 10-year events or 25-year �vents, Cu�*�ent design trencls are to use a 10-year event being the prc�bab].e size oF a typical storm. Th3s bas3n was reviewed based on th� more consPsvative 25-�jear event, a larger starm, which would be less likely to oc- cur. Therefore statisitics pertaining to run-off given in this r@v3ew or pxevious calculations wi11 be larger in magnitude thara �would actually �ccur with a typical storm. In consideration of downs�r�am property owners. two elements of design could ?ae oon- sidered, detentior� and er�sion control. Detention �returns fih� increased runoff, due tp develapment back to i�s natural rate. It fs our und�rstandin.g that the city does not all�w detention, therefore this was not consid�red. Erosion control is �ddressed by providing a rip-rap pad which reduces the run-off to a n4n- erodable veloca.ty. Ses Dra3nage Discharge protection calcula- tians d�ted May 30, 1991 . Scolar Pra erty The natural swale of � the existing b�sin runs through the south- ,,; w�st portion of the Scolar p�oper�y. Directl�� e�st (on fihe ��,:. downstream side) the swale is blocked by S.W. ?9th Av�nue. The Y � sw�le_as we],I c1e�3ned b � n�t,.�ral terrain and has established SUITE 19 • 1750 S.W.SKYLINE BWD. • PORTLAND,OR�GON 97221 ■ (503)297-1458 � , �� _� ,:. � _ -- �w- ; , r _. � , t, ..,x,� , „ -: -.r z+ "{--�n -T^^Rt.. h � _,.., �� ,:., � �f!�. . r'.7 ' '��`1., ..n G T"`,'1'1':'�.-.'lc * ;.. ..� ,.,:,: „., _. . ,... .. ., .. , . . _ , . �,, . ., . . ...... .. . ... ..... .. ... „ ..._ ,..,_.._ ....,._ . . ..... . ...., ,. >. . _. � � . _._ ,�� ..J��'� . .✓, � . �_,�, r'. vegetation. Runoff released directly upstream of the praperty due to a large storm (25-yearj calculates ta be 9.4 cfs. The rip-rap pad will release the runaff at a depth vf 0.46 feet w3th 1 .6 fps velocity. This is a nara-eradable velocity wh3ch wauld � not adversly etPec� the property. During an '"average" stcrm, �he runoff will be �ign3ficantly less . A culvert is to be con- r' structed under 139th which will �relieve ex.isting of potential �` ponding on the Scolar property. � � Hawle�r Pro�ertY ti Tha basins natural swale travels from the west �ide of the property to th� nortMeast side . The �wale is braad and less defined. Runoff is released �t 11 . 5 �fs f�°�m th� �'?9th Ave. culo� vert v��ssing. - The��existing swale has we11 establistxed vegeta-- tian with tl�e installation of the �YT9th Ave. CLtIV�I"�a �the deten- tion effect ar�if3cially created by ?�th Avenue w311 b� e13.minated, returning the runoff in the natur�l swale closer to its origina.l state. A rip-rap pad is to be construted at t�e outfall W�1�GY1 wi11 reduce the velocity to pro�ect against ero- sior�a The Hawley's have participated in direcfiing the location � of th� Autfall in consideration of future devel�pment to their property. See letter dated June 11 , 1991 . Their concerns were t� minimize seaonstruct3on efforts on the future ext�nsion af the public storm system. The culvert is extended near the right-of- way, eliminating the ne�d for a concrete headwall and reduGing the amount of rip-rap. The runoff would be dit�hed ta the natural swale and allowed to re�kurn ta its natural basin. Max�ciene II Apartments ' This property is loc�ted approximately 1,200 LF downstream of �the Raze Meadows developanent. The existing swrale directly up�tream (to the west of the apartments) is a broad swale. A portion �f th� apartm�nt site was built near the swale with no aparent can- sideration for upstream drainage. Considering the entire basin, the Raze Mead�w� subdivision would increase the run�ff rate � clirectly txpstream by approximately 5�. In review of the tngog- � raphy it appears a ma�or portion vP �he runoff bypasses tY�e si�e to the sou.th�. As a result of the Raze Meadows development, �the �� apartment s3te would not be receiving a significant increase 3n i; runoff tkxan what would normally occur in the unimproved basin. Based vn th� above discussivn, I bel3eve the proposed developnt�nt would not significantly impact the downsfiream property ownerso Thank You.
