II: General Information A. Background is action to amend the UGB was precipitated by the discovery that the City of Th rin field had mistakenly issued a residential building permit for tax lot 900. Sp. g ometime after the final occupancy had been This error was not discovered until s ranted. The other lots have been included in this UGB amendment for several g reasons includin similarities in development, lot size, common•boundar~es• and • $ B, Tax Lot 800 also is occupied by a single proxlm~.ty and relationship to the UG famil home but construction occurred prior to state law requiring adoption of urban Y rowth boundaries. Tax Lots 901 and 902 are vacant and Tax Lot 500 is the site of a g Weyerhaeuser Company water discharge structure. ., B. Description of Site Each of these lots front on Hayden Bridge Road and extend east and/or north to the McKenzie~River a roximately 22fl feet}. The UGB abuts each of these lots along ~ PP their entire Ha den Bridge Road frontage and along the western and southern y ivel . boundaries of lots 800 and 500, respect y The to o rah of these lots is characterized by a uniformly steep slope away from P g~ P y 'v r. The maximum elevation is 510 feet ion lot Hayden Bridge Raad towards the rl e 500 and the minimum elevation is 452 feet blot 800} which is the ,mean high water } , mark of the McKenzie. The 100 year flood elevation along this portion of the river is 4b0 feet. All but the narrowest margin of lot 800 and 902 is above 4b0 feet. The 4b0 foot mark for lots 901, 900 and 500 is precipitous. FEMA flood naps show a small area of lot 800 adjoining the river in Zone A-b X100 year flood}. An equally small area of Zone B (between 100 and 500 year flood} abuts the A-b Zone on lot 804. The remainder of lot 800 and literally all of lots 540, 900, 901 and 902 are in Zone C. Zone C is described as an area which may be subject to minimal flooding during a_.. 500 year event. There are two soil types found on these lots. Nelda Silty Clay Loam predominates on lots 500 900 and 901 .and intrudes nominally into 1ot~902. Chapman Urban Land Complex makes up the remainder of lot 902 and all of lot 840. Nelda is used for hay, pasture, cultivated crops, timber production, recreation and homesites. Because this soil is underlain with deep deposits of gravel, it is ' 1 drained and re wires substantial irrigation during droughts. This soil does raped y Q not rovide maximum yield unless fertilized with lime, nitrogen and phosphorous. P Its subclass is IIIe. Cha man is used mainly for urban development.. It is also used for yards and open P areas around and between buildings. Because of the mixture of natural and man--made deposits, na capability rating is assigned to Chapman. C. Plan Designation and Zoning The lots are zoned E--40 and the Metro~Plan diagram does show these properties as a ricultural although it could be argued that lot 500 is shown as park and open g s ace. The matrix found in Appendix C of the Metro Plan keys the exclusion of these P lots from the UGB to one or more of the following characteristics: Exhibit A -~ Findings -- 2
