LOCATION OF THE PROPERlY The subject property is located at 8067 Thurston Road, outside of Oty limits, but within the Urbanizable Fringe; and further described as Tax Lot 206 on Tax Assessor's Map #17-02-36-2. DECISION Tentative Plan approval, with conditions, as of the date of this letter. Datel Received. Planner: AL 7/;r1JcII / I . . , BACKGROUND/SITE INFORMA TlON The land area to be partitioned is approximately 10 acres. The property is located on the east edge of the Urban Growth Boundary. A dwelling is located on Parcel 1; a manufactured home is proposed for Parcel 2: Surrounding land uses are residential and agricultural. The zoning of adjacent property is: Exdusive Fann Use to the north, Rural Residential to the east, and LO'N Density Residential to the west and south. The property is not part of any Refinement Plan area. WRITTEN COMMENTS Umited Land Use Decisions require the notification of property owners/occupants within 300 feet of the proposed development allowing for a 14 day comment period prior to the staff decision. No written comments were received. CRITERIA OF APPROVAL Section 34.050 of the Springfield Development Code states: The Director shall approve. approve with conditions or deny the request based upon the following criteria: (1) THE REQUEST AS CONDITlONED FULLY CONFORMS WITH THE REQUIREMENTS OF THIS CODE PERTAINING TO: LOT SIZE AND DIMENSIONS, THE EFFICIENT PROVISION OF PUBUC FACIUTlES AND SERVICES, STREET IMPROVEMENTS AND CONSIDERATlON OF NATURAL FEATURES. Lot Size and Dimensions V'vtlere all of the requirements of Section 29.070(5) are met (see belO'N), the minimum lot sizes allO'Ned in the LO'N Density Residential DistrictlUF-10 under Section 16.030 of the Springfield Development Code is 4,500 square feet. Both parcels meet this standard. See belO'N, under "Other Applicable Standards," for discussion of parcel size standards in the UF-10 District.) Public Facilities and Services 1. Water SDC 32.120 states: "Each development area shall be provided with a water system having suffidently sized mains and less lines to fumish adequate supply to the development. Rre hydrants and mains shall be installed by the developer as required by the Fire Marshall and the utility provider." Water district service is not available to this property. Potable water will be provided by an on-site well that currently serves Parcel 1. Suffident evidence must be submitted to shO'N that each parcel will produce an adequate supply of potable water. The applicant must either prepare a well log report which demonstrates that 80% of the wells within the vidnity of the subject property produce at least five gallons/minute. or conduct a five-hour pump test. The recovery rate must be greater than 200 gallons per day (see endosure). 2 Date Heceived: i/~/)o'/ Planner: AL I t . . ~ - -., . - , ../ -.' -" ., .- Please contact Harry Youngquist at Lane County Environmental Health (687-4051) for assistance. A copy of a recorded easement showing legal access to the well on Parcel 1 must be provided. Fire protection will be provided by the Springfield Rre Department. 2. Electridty SDC 32.120 (5) states: "An applicant proposing a development shall make arrangements with the City and each utility provider for the dedication of utility easements necessary to fully service the development. The standard width for public utility easements adjacent to street rights-of-ways shall be seven feet. The minimum width for all other public utility easements shall be 10 feet unless otherwise specified by the utility provider or the City Engineer..." Eugene Water and Electric Board (BM::B) is the service provider for this property. Service is available from the overhead line in Thurston Road. Individual electric service is required for each parcel. No PUEs have been requested at this time. Please contact Rich Deluna at BM::B (484-2411) with any questions. 3. Surface Drainage Piped storm sewer is not available to these properties. The applicant has not indicated how surface drainage will flow from the property. A drainage plan must be provided prior to issuance of a building permit for the dwelling on Parcel 2. 4. Waste Water Disoosal .'~ The City sanitary sewer is located over 300 feet away and is not available to serve these parcels. A shared septic system will provide sanitary waste disposal to Parcel 2. Verification from the Lane County Sanitarian that both parcels can be served by the on- site septic system must be provided. A drainfield easement showing legal access to the septic system on Parcel 2 must be provided. Street Improvements 1. Right-of-Way Dedication Section 32.020 (1 O)(a) states; 'Wlenever an existing street of inadequate width is abutting or within a development area requiring Development Approval, additional right of way shall be required." Thurston Road is dassified as a minor arterial street. The minimum right-of-way for a minor arterial is 70 feet {Ref. SDC 32.020 (3)}. The right-of-way shown from the centerline of Thurston Road to the property 'frontage is 60 feet. In order to meet this standard, an additional five feet must be dedicated from the entire frontage {Ref SDC 32.020 (10) (a)}. A legal description of the area to be dedicated must be provided with the Final Plat. The City will prepare a letter in support of the dedication. 3 Date Received: 7!~/JbIf Planner: AL . . . Inventoried Natural Features The Metro Plan and the draft Natural Resources Special Study, the National VVetlands Inventory Map and the Hydric Soils Map; the Washburne Historic District and the list of Historic Landmark Sites, have been oonsulted. There are no inventoried natural or historic features located on the development site. (2) THE ZONING IS CONSISTENT WITH THE METRO PLAN DIAGRAM AND/OR APPUCABLE REFINEMENT PLAN DIAGRAMS. The Eugene-Springfield Metro Area General Plan designate the subject property as Low Density Residential. The property is zoned Low Density ResidentiallUrban Fringe Overlay District. The proposed partition would create two parcels in oonformance with the Plan designations and the prescriptions for lot size and dimensions specified in the Springfield Development Code. (3) DEVELOPMENT OF ANY REMAINDER OF THE PROPERlY IN THE SAME OWNERSHIP CAN BE ACCOMPUSHED IN ACCORDANCE WITH THE PROVISIONS OF THIS CODE. The property was previously partitioned in 1989 (Journal Number 89-03-34). The application was evaluated for oonformance with Section 34.050 of the SOC. Criteria (2) states: "(2) The Mure use for urban purposes of the remainder of the property under the same ownership shall not be impeded." The staff response to this criteria states, "Since this property is within the Oty's Urban Growth Boundary, only the two parcels proposed can be created until the land is annexed to the City." The finding was oonsistent with the existing administrative policy. Artide 34 was subsequently amended and no longer oontains this criteria. The Future Development Plan submitted with this application is intended to accurately reflect the Mure development potential of the parcels created by this partition and ensure that the property can be developed to urban densities. The draft Local Street Plan for the Oty of Springfield and the Urbanizing Area shows a Mure local street extending south from Thurston Road along the west property line of the subject property. In order to be oonsistent with Mure transportation plans for the area, the FDP must be revised to show this Mure street oonnection with the potential development of the property at urban densities. (4) ADJACENT LAND CAN BE DEVELOPED OR IS PROVIDED ACCESS THAT WILL ALLOW ITS DEVELOPMENT IN ACCORDANCE WITH THE PROVISIONS OF THIS CODE. . All adjacent properties have access to a public street. This partition has no adverse affects on access to adjacent land. 4 . -,1'-' ,";ccdiveu: i' ~/;()'I Planner: AL . . , DEVELOPMENT REQUIREMENTS OF SOC 29.070 (SPECIAL USE STANDARDS) In addition to the standards specified above, proposed partitions in the urbanizable area shall meet the additional standards and criteria specified in Section 29.070 and shown below: (1) General (a) The owner of any property requiring Type II, III, IV Development Approval, or Type I Development Approval with respect to new single family residences and Site Plan reviews, shall sign an Annexation Agreement An Annexation A:lreement will be required for each parcel. (b) The lane County Sanitarian shall certify that the proposed individual waste water disposal system meets D.E.a. standards prior to Development Approval. r2etter'~r other documentation from the Lane County Sanitarian will be required stating '- that the new parcel has been approve<;j for septic: A copy of the recorded easement document for joint use of the septic system must be provided.-' . (5) Partitions. In addition to the standards specified in this Subsection, proposed partitions in the urbanizable area shall meet the standards and criteria of Article 34 of this Code and the standards of Subsections (1)(a), (b), (c) and (f) of this Section. (a) The minimum area for the partitioning of land shall be 10 acres except as permitted below: (b) Except in areas designated MDRlUF-10, any proposed new parcel between 5 and 10 acres shall meet the following standards: 1. The efficient and full urban use of the property, or neighboring properties shall not be limited by the partition; See (3) and (4) above. 2. A Future Development Plan for the urban development shall be required where the property is redivisible into small parcels. The Future Development Plan shall be in accordance with the redivision plan procedures and requirements of Subsection (1)(c) of this section; The Future Development Plan shall provide sufficient detail for evaluating and ensuring redivision in accord with City requirements and Mure road plans for the area. 3. Proposed land uses and densities shall conform with the Metro Plan and this Code' . , The applicant proposes to site one manufactured home on the newly created 5 Date I~eceived: 7 It ,/J-<>J/ Planner: AL I I . . . parcel. The density range for Low Density Residential (LOR) is 1 to 10 dwelling units per acre. The FOP shows how future development of the parcel will conform with Metro Plan densities. The lot sizes proposed by this partition exceed the minimum lot size of 4,500 square feet allowed in the LOR District. (c) Any proposed new parcel less than five acres shall meet, in addition to the standards of Subsection (5)(b) of this Section, ~ of the following standards: 1. That the property to be partitioned shall be owned or operated by a governmental agency or public utility; or The parcel is privately owned and thus meets the standard cited above. 2. A majority of the parcels located within 100 feet of the property to be partitioned shall be smaller than five acres. There are seven parcels within 100 feet of the subject property of which three parcels are smaller than five acres. Thus, a majority of parcels located within 100 feet of the subject property are rnt smaller than five acres. SDC 29.070 (5) (c) is not met by either standard (1) or (2). In order to approve this application, the partition must show both parcels a minimum of five acres in size. The applicant has provided an altemate plan, showing this possibility, however, the plan must be consistent with future street plans. 8. In addition to the foregoing provisions, this partition process shall comply with Oregon Subdivision and Series Partition Control Law as set forth in ORS 92.305 to 92.495. This partition is processed in compliance with the state laws stated above. SDC 29.070 (5) (d) is not applicable to this partition because the provisions of this Subsection apply only to property in an area targeted for City sanitary sewer extension within 5 years. This area of east Springfield is not targeted for sanitary sewer extension, as shown on the City's Capital Improvement Program 1995-2000. CONDIllONS OF APPROVAL The Director has determined that the Tentative Plan satisfies the requirements of the Springfield Development Code and that conditions are necessary to satisfy the standards of this Code. The applicant will have up to one year from the date of this letter to meet any attached oonditions or Development Code standards and to obtain Final Partition Plat approval. For partitions in the urbanizing area, three copies of the Final Plat must be submitted to the Lane County Surveyor and Planning Manager prior to the signing of the mylar by the Planning Manager. A reproducible copy of the recorded Plat shall be submitted to the City Surveyor. No prooerty may be transferred until the Partition Plat is recorded. I)at~n~~c~~ed: ~~~/){)II . . . 1.

QUESTIONS Please call the Development Services Department at 726-3783 if you have any questions regarding this process. PREPARED BY Lauren Lezell Planner J .Endosure Date rbceived:4~/Jp/l Planner: AL . . f DEMONSTRATION OF WATER AVAILABILITY Lane Code 13.080 requires that when a division is to be served by individual water systems, sufficient evidence shall be submitted to show that each parcel or lot will have available at time of development an adequate supply of potable water. IF AN ADEQUATE SUPPLY OF WATER CANNOT BE DEMONSTRATED OR AN ALTERNATE WATER SUPPLY DEVELOPED; YOUR PARTITION OR SUBDIVISION WILL BE DENIED. THEREFORE IT IS IMPERATIVE THAT THE WATER ISSUE BE RESOLVED PRIOR TO EXPENDING SIGNIFICANT EXPENSE, TIME AND EFFORT. In areas designated by the B/CC as water quantity and quality limited areas (Lane Manual Section 13.010) Lane Code 13.050(13)(c)(i) requires that these areas have an aquifer test performed along with any additional work that may be required to demonstrate long term supply. Aquifer tests must be conducted and analyzed by a licensed geologist or engineer and must demonstrate: tra~smissivity, permeability, storage coefficient and specific yield. Chemical tests will Gt required as appropriate. A prediction of long term supply is also required. A qualified professional requires "a water budget including infiltration rate, recharge, change in storage J runoff, evapotranspiration and precipitation in order to support the prediction. In areas where water quantity and quality is a concern but not defined by the Board as limited, _the standards of Lane Code Ch l3.050(13)(a)(b)(d) will apply. These standards require that an adequate demonstration of water availability be made and the long" term supply addressed. In meeting these requiremments, the County may ask for any or all of the following: 1) an aquifer test as is required in quantity'- limited areas, 2) a 5 gpm well on each lot to affirmatively demonstrate water, 3) a minimum 5 hour well test (pumping test) with analysis or 4) an analysis and listing of wells and-we.ll. .logs.-f"". Iohe -a-l'ea.adj acent-to- the 'propos-edud-eve-r-opmen1: :----Arry-or--all- ---- of the above req~irements may be necessary to adequately demonstrate water. Again, we recommend a prudent approach and that you NOT wait for water adequacy demonstration until late in the process. If adequate water is not available, your development will be denied. Monies already spent on roads, surveys and other installations will be wasted. It is a very important step to prove water first; it is not a valid assumption that every parcel has adequate water available. Within the bounds of Lane Code and Lane Manual, the County Hydrogeologist will work wi.th applicants to meet these requirements. The applicant should ultimately be prepared to drill a well on each parcel, perform a five (5) hour pumping test in non-limited areas or be prepared for a full scale aquifer test in quantity and quality limited areas. New Wells Where a new well is being placed on each lot to demonstrate adequate water supply a 5 gpm minimum standard will be used. It may be required that the well have a 5 hour pump test to confirm the flow if the area is suspected or known to have highly variable flows. Pump tests will generally be required on wells more than 6 months old. (See below) Conducting an Acceptable Pump Test In those 'instances where the aquifer or water bearing for the hydraulic characteristics of the aquifer, formation need not be evaluated a pumping test can provide a 1r/~1/ / Date, r<:eceived: Planner: AL "-' . . , REgy I RUle~ TS FO~ SHi\~ED j,--A TEJ1_5J:5JJi~S Lane Code 9.552 defines community \1dt':'I' systcms to include t110'iC COI"!lIlmity systems not subject to State regulation because they Pl'ovide l'late,' to t,,/O (2) 01' tlwee (3) set'vices, These systeliis /lave cOI::e to be kr.Oivn as ushl'lred ~'h)tu~' SY$tCIlISll. In the case of new shared watcl' system, it is clear that the intent of Lane Code 9.550 to 9.568 and Lane i1anual 9.100 to 9.180 is to require that these systems meet the require"lents of cOllununity water syste'"s including all construction stan- dards which exist at the time of the creation of the Ivater systcm. If, however, a shared water system is already in existence and a par.ti tion, subdivision or property line change is prODosed, the fo110"lin9 guidelines sho,Jld be used: 1. If the proposal calls for additional connections to an existing system, the system must be upgraded to meet all applicable requirements as a condition of approval. 2. If no physical modifications to the existing system are proposed but a partition, subdivision or property line change results in a modification of the legal relationship between users of the shared system, the following requirements will be a condition for approval: (a) Necessary easements, including a 100' radius circle of leqal control around the I"ell, to the water source and documented for all parties; and .(b) Pipeline easements are provided to all parties; and (c) Chemical and Bacteriological anlaysis are requit'ed; and (d) An area for water source replacement is provided if the existing system does not meet the setback requit'ements which exist at the time of the partition, subdivision or property 1 i ne change. . , 3. If no physical modifications to the system are proposed and the parti- tion, subdivision or property line change does not effect the legal relationship between the users of the shared system, requirements are: (a) Chemical and Bacteriological analysis are required; and (b) An area for water source replacement is provided if the existing system, following the proposed action, does not meet the setback requirements which are in effect at the time of the partition, subdivision or property line change. In any case, the presence of a situation l'ihich could be deemed to threaten the heal th of the publ ic will result in a modification of those facto,'s "hich cause that problem.

The pumping test, if intended for use as part of a land division or loan review process, should be conducted by a licensed professional com~tent in the field and a report submitted by that professional to this office. The test should be of five hour pumping duration (as the name implies) and measure and record the following information as the minimum raw data: 1. Static Water level 2. Pumping level 3. Drawdown 4. Recovery 5. Residual Drawdown 6. Well Yield (pumping rate) 7. Specific Capacity These measurements should be made before pumping begins, during the oump- ing phase and during the recovery phase as necessary.

The measurement is then read off the markings of the electric cord that lowers the tip into the well. Also useful in measuring the water level in the pumped well is the air tube method. A rigid tube is put down the well and pumped full of air to evacuate all the wat8r from the tube. An air pressure gauge on the tube (some are calibrated in "feet of water" for this purpose) is read to determine the length of tube that is submerged. Therefore, you must know the total length of tube that is inserted down the well. If the air gauge is not calibrated in feet. of water, a conversion factor must be used. The reading in PSI is multiplied by 2.31 to convert it to feet of water. Depth to water is found by subtracting gauge reading from the total length of tube. Depth = Total length of tube - gauge reading in feet of water. In obs~vation wells, the wetted tape method may be used. The tape (with a weight attached) is covered by chalk at the lower end, lowered down until the end enters the water (an estimated distance to water is often needed). The top of the tape is read at a reference point (usually the top of the casing) and the wetted portion of the tape subtracted from the reading. A sample schedule of measuring water leve ls would be: -every 30 seconds for the first five minutes -every five. :minutes for the next one hour -overy 15 minutes for the next two hours -every hour after three hours.

The-more rapid the rate the- shorter, the sampling interval. 4) Observation wells do not need to be of the same diameter as the pumped well (two inch wells are common). They should be between 100 and 300 feet from the pumped well. One observation well may be sufficient, however, circumstances may require more. Occasionally a test may be completed without an observation well if sufficient data from the pumped well is available. Observation wells must be placed into the same aquifer or aquifers that are being tested. This may require setting observation wells at various depths. (See diagram C) 5) The pumped well should have had suffic.ient rest time from the time it was last pumped to be at completely static conditions. That is, it should be completely recovered from any previous pumping before the test begins. 6) A complete log of all pertinent events and associated observations should be kept, with times. Examples of items that should be logged are break downs, accidents, movement of heavy equipment near observation or pumped wells that may cause water level fluctuation ~ue to compression, temporary changes in flow rate or any other event that may cause a change in the procedure, flow rate, schedule or aquifer characteristics. ANALYSIS After completion of the aquifer test the collected data must be analyzed using one of the accepted procedures for deriving transmissivity, permeability, storage coeffient _J ',.;ceived: 1ff~fI Hanner: AL . . CONDUCTING AN ACCURATE AND ACCEPTABLE AQUIFER TEST An aquifer test is conducted to determine the ability of an aquifer to store and then deliver water to a ~ell. The information from the test is necessary to accurately assess the long term water supply available in the aquifer. By using several aquifer tests on wells covering a larger area, the maximum usage the aquifer can sustain can be determined and limits can be set to assure all users of an adequate long term water supply. In order to make this assessment accurate data must be supplied to the proffessionals doing the calculations to determine aquifer constants. DATA COLLECTION The data collected and the method of collection are as follows: 1) The rate of pumping (in gpm) must remain constant throughout th& test. 2) The water levels in the pumped well and one or more observation wells must be accurately measured beginning with static water level (the pre-pumping water level) and water levels measurements at prescribed intervals thereafter according to a schedule. 3) Each measurement and activity must be accurately timed from the beginning of the pump test until.the end of the recovery phase, in minutes. 4) Rec.overy. (water level rise after pumping has stopped) nlUst be recorded (and. timed) for either: a) a peri.od equa..1 to...one .half the time_pumped...or.J.Dng.er, .__ ______. _ . _ u.._ ... . . b) or until the water level returns to the static water level. Aquifer tests that do not conform to the above standards will not give acceptable results and will necessitate re-testing. An aquifer test should be approximately 24- 72 hours in duration, pumping at 1/4 to 1/2 the maximum yield expected of the well. In no case will an aquifer test of less than 24 hours be accepted. A pump or flow test (not an aquifer test) of less than 24 hours may be accepted in Some cases but the data collection requirements will remain the same. The following hints may be useful in meeting the above requirements: 1) The regulation of the rate of flow from the pump should be accomplished by adjusting valves rather than the pump speed. This is more accurate, subject to less fluctuation and can be accurately controlled. The pump, pipe and valve size should be such that the valve is about 1/4 open when the desired pumping rate is being maintained. 2) Several methods of measuring pump inK rates are available such as: a) Measuring the time reqUired to fill a known volume, i.e. a five gallon bucket in one minute is equal to 5 gpm. A commercial water meter that measures gpm directly. A meter which indicates the total amount pumped.
