STAFF: Barbara Rich, Assistant Planner The Hearings Officer hereby adopts the Staff Report, as modified below, and the ESEE analysis referred to in the Staff Report as Exhibit A. The finding set forth at page 13 of Staff Report under DCC 18.136.030(D) is modified by the addition of the following language: Normally, just having more information available regarding a property is not sufficient to establish a change in circumstances which warrants a zone change. However, a request to rezone property to SM is unique in that the gathering of more information is specifically listed as the first step in the Goal 5 inventory resource process. See OAR 660-16-000. In addition, the act of gathering of more information for the Goal 5 inventory process is relatively comprehensive and therefore, relatively expensive. These two circumstances present a unique situation in which the existence of more information after the current zoning qualifies as a change in circumstances necessary to support a request for a zone change. Accordingly, the Hearings Officer recommends approval of the applicant's requests to amend the Comprehensive Plan to list its site on the county's inventory of mineral and aggregate resources, designate the site surface mining on the plan map, and rezone the site from EFU to SM, except for the southwest portion of the site above 3,800 feet in elevation. -1- (PA -96-3 & ZC-96-4) Mailed this 2�Qy of September, 1996. -0 156} Christo C.

PA-96-3/ZC-96-4 Page 1 This land use action is a quasi-judicial zone change and plan amendment that involves lands designated for agricultural use. DCC 22.28.030(3) requires the Board of Commissioners to hold a de novo hearing on the plan amendment application. DCC 22.28.030(4) states that if the plan amendment has been consolidated with a zone change, that any party wishing to appeal the Hearings Officer's decision on the zone change must file an appeal of that decision. FINDINGS OF FACT: A. LOCATION: The subject property is approximately 15 miles southeast of Bend off of the Old Bend -Burns Highway. The subject property is identified on Deschutes County Assessor's Map #19-14 as Tax Lot #700. B. ZONING AND COTSIVE PLAN DESIGNATION: The entire property, 205.15 acres, is zoned EFU-HR, Exclusive Farm Use, Horse Ridge Subzone. This property is also within a Surface Mining Impact Area (SMIA) Combining Zone due its location adjacent to tax lots 500 and 600 which are SM zoned property. The entire property is located within a Wildlife Area (WA) Combining Zone. The Comprehensive Plan designates the subject property as Agriculture. C. LOT OF RECORD: The subject property is a legal lot of record as it is first described in its present form in a deed dated November 20, 1930 and recorded in Volume 49, Page 319 of Deschutes County Records. D. SITE DESCRIPTION: The property is 205.15 acres in size and is located approximately one-half mile off of Highway 20 along the Old Bend -Burns Highway. Approximately 10 acres of the property lies north of the Old Bend -Burns Highway. The northern portion of the subject property is basically level but the southern portion is steeply sloped upward and forms the north flank of Horse Ridge. The highest elevations are found on the southwest corner of the parcel. Vegetation on the site consists of juniper, sage brush and other vegetation native to the region. E. SURROUNDING PROPERTY: Surrounding properties include land managed by BLM, a state owned surface mine which is currently inactive, a recently rezoned privately owned surface mine, and small privately owned farm parcels. The recently enlarged "Moon Pit" surface mine PA-96-3/ZC-96-4 Page 2 is located proximately 2 miles east ,f the-� - property and the Horse Ridge Research Natural Area is located approximately one mile southeast of the subject property. This geographic area of interest, designated Scenic and Vegetated Communities, encompasses a portion of Horse Ridge, a feature which comprises the. southern portion of the subject property and which extends west beyond the boundary of the subject property. E. REQUEST: The applicant is requesting that the County place the subject property on the County's inventory for sites with significant mineral resources and amend the plan map designation from Agriculture to Surface Mining. A zone change from EFU to SM is also requested. The applicant has submitted a burden of proof statement, revised on August 16, 1996, in support of this application. This statement includes attachments relevant to the plan amendment and zone change requests, including: 1. Geotechnical Survey of the site prepared by Siemens & Associates, including a Quantity/Quality Assessment of mineral resources on the site, 2. Proposed ESEE Analysis Findings and Conclusion, 3. Photographs of site.and surrounding area 4. Vicinity map, and S. ODFW Proposed Changes to Surface Mining Operating Guidelines in Zoned Big Game Winter Ranges. F. AGENCY COMMENTS: The Planning Division solicited comments from affected agencies and departments. Their responses are as follows: Deschutes County Public Works: "Please note that the old state highway is under the jurisdiction of the Oregon Department of Transportation and not Deschutes County. The state may well want the applicant to make improvements to this road to offset the wear and tear that the heavy trucks serving this proposed land use would make on the old state highway. The site adjoins to existing SM zoned sites and is an area generally surrounded by open range land owned and managed by the Bureau of Land Management. The old state highway connects with Highway 20 to the west which in turn provides a direct level route into Bend which would be the major market for the aggregate from the applicant's proposed construction aggregate mine. It is up to ODOT serving the site is it is a state road PA-96-3/ZC-96-4 Page 3 to determine if the road system adequate for the intended site as serving the site. County Public Works will have some additional comments i� this -land use request is approved and a specific site or development plan is submitted at a later date." Deschutes County Environmental Health: "Any outbuildings or offices requiring toilet facilities would require a septic site evaluation and septic system." Deschutes County Property Address Coordinator: "The address of record for this property is 26300 Highway 20." Deschutes County Assessor: "No Comments." watPx=ster, District 11: "No Comments." Oregon Department of Fish and Wildlife: "1. The property is located in the northern portion'of the County recognized (as the] North Paulina mule deer winter range. The area encompassed by this site is of particular importance for mule deer during severe winters. ODFW would like to recommend that any plan amendment/zone change for this site apply the Deschutes County winter range operation standards applicable for this area (Ordinance No. 95-080). 2. The tree cover on the slope of Horse Ridge provides winter security (hiding) and thermal cover in addition to foraging habitat. ODFW would prefer that this habitat not be altered because of its importance to wintering deer during severe weather. We therefore recommend that Deschutes County limit the zone change to the flats and lower slope, below the 3800ft elevations." The following agencies had not commented at the time the staff report was prepared: Department of Geology and Mineral Industries (DOGAMI), Highway Division, ODOT, and ELM. G. PUBLIC COMMENTS: The Planning Division sent notice of the application to all property owners within 500 feet of the subject property. One letter was submitted from the public regarding these applications expressing the following: "As owners of a grazing allotment that adjoins the proposed surface mines, we have no objection to the zoning change. R&R Equipment. rental should be aware that there is a fence crossing the proposed mine that is a border of our allotment. We would like a PA-96-3/ZC-96-4 Page 4 IV. A. condition of he zoning change [be] t protect and re -align this fence with their property boundaries. "It is our understanding that the property was once a part of Evans Well Ranch and that is why the fence is on deeded property." REOUIRED FINDINGS AND CONCLUSIONS: Comprehensive Plan Inventory Listing and Plan Amendment The goal of the Surface Mining chapter of the comprehensive plan is: "To protect and utilize appropriately, within the framework established by Statewide Land Use Planning Goal 5 and its implementing administrative rules, the mineral and aggregate resources of Deschutes County, while minimizing the adverse impacts of mineral and aggregate extraction and processing upon the resource impact area." STAFF FINDING: Statewide Planning Goal 5 and its implementing rule, OAR Chapter 660, Division 16, require local governments to identify aggregate resources through an inventory of resource sites throughout the county and to determine the significance of a mineral resource site by evaluating the location, quantity and quality of a particular site. This application is being reviewed within the framework established by Statewide Land Use Planning Goal 5 and its implementing administrative rules. The following plan policies, from the Surface Mining section of the Resource Management section of the Comprehensive Plan are applicable to review of this application: 6. Land use decisions of the County shall be based upon balanced consideration of the location, availability and value of mineral and aggregate resources, and conflicting resources and uses as designated in the comprehensive plan. STAFF FINDING: The County's decision regarding this application will -be based upon a balanced consideration of the location, availability and value of the mineral and aggregate resource and conflicting resources and uses designated in the comprehensive plan. The plan identifies this area for deer winter range use and designates Highway 20 as a Landscape Management feature. These factors have been considered in this review. PA-96-3/ZC-96-4 Page 5 8. Sufficient SM (Surface Mining) zoning shall be maintained by the County to satisfy, at a minimum, the demand for mineral and aggregate resources of the County as reflected by the data contained in the comprehensive plan. The County shall not deny SM zoning for any mineral and aggregate resource site for the sole reason that the demand of the County for that resource has been satisfied by the SM zoning of other sites. STAFF FINDING: The geotechnical report prepared by Siemens & Associates for the applicant (Burden of Proof) indicate that the 205 -acre property contains three types of mineral resources in sufficient quality and quantity for extraction: sand and gravel, cobbles and boulders, and basalt. The quantities of material estimated to be present in these categories are 3,600,000 cubic yards, 200,000 cubic yards and 3,900,000 cubic yards, respectively. Other sites exist in the County for these resources, including two surface mines adjacent to the subject property. The County's inventory includes approximately 35 years worth of sand, gravel and rock based on the use rate of 2 million cubic yards per year determined in the comprehensive plan. The resource identified at this mine comprises approximately 3% of the resources identified in the county as a whole. It is anticipated that use of aggregate resources will continue to occur and will fluctuate with market demand, as is the case at other sites designated for surface mining. 10. A mineral and aggregate resource site not on the current inventory shall be placed on the inventory and zoned SM when the following conditions are met: (a) A report is provided verifying the location, type, quantity and quality of the resource; and STAFF FINDING: -The applicant has submitted a geotechnical report by Siemens & Associates dated November 10, 1995. The report indicates that significant resource material is present on the property of sufficient quality to meet highway or general construction standards. The location of the different types of materials in the southern portion of the property is indicated on a site map and cross- sections developed with seismic testing, test pits and borings. PA-96-3/ZC-96-4 Page 6 The report estimates the following amounts of material (in million cubic yard estimates for volume) within the 205 -acre area: Stratum Material Thickness Volume 2m Topsoil 0-20' 1.2 2s Sand w/ Gravel 0-60'+ 3.6 2g Cobbles & boulders 0-151+ 0.2 3q Basalt 0-201+ 2.2+ 3m Basalt 1001+ 1.7+ The conclusions in the report are drawn from on-site examination and laboratory analysis of the results of 29 trackhoe test pits, 10 air percussion drill cutting samples, and 7 seismic surveys. The report concludes that the Stratum 2s sand and gravel comprises the primary aggregate resource on the subject property. The other aggregate resources identified on the site are limited by either quality or quantity but are still considered to be viable resources. The geotechnical report states that the topsoil available on site could be marketed or retained on-site to facilitate reclamation. (b) The Goal 5 conflict identification and resolution (ESEE) process results in a determination that the resource is of sufficient importance relative to conflicting resources and uses, if any, to require protection. STAFF FINDING: The applicant submitted an ESEE Findings and Decision (attached to the Burden of Proof statement) to identify and resolve conflicts with surface mining. Planning staff has revised this document into a Conflict Analysis and ESEE Findings and Decision for Site No. , attached as Exhibit A to this staff report and incorporated herein by this reference, for possible adoption by the Board of County Commissioners, as required by OAR 660-16-000. Both documents conclude that the use of the property as deer winter range is a conflicting Goal 5 resource. The County's ESEE concludes that preservation of the property to maintain scenic views is a conflicting Goal 5 resource. PA-96-3/ZC-96-4 Page 7 �kju The County, in !990, developed a program in which surface mining operations are prohibited during the winter- months in designated winter ranges. Subsequently, ODFW and the operators/owners of the Moon Pit developed a modified winter closure program for the North Paulina winter deer range. The subject property is near the southern border of the North Paulina deer winter range. The recommended program to meet Goal 5 at this site, therefore, includes closure of the site for blasting, mining and rock crushing activities, during winter months when snow depth for the month is more than 85% of the long term total for the month and a total of 20 deer are counted in any combination of four transects (to be determined in consultation with ODFW). [Reference: ODFW Proposed Changes To Surface Mine Operating Guidelines In Zoned Big Game Winter Ranges.] In addition, based on the site visit and comments from ODFW, staff finds that the most significant habitat -on the site and the area which would most impact the scenic views from Highway 20 are found on the sloped area in the southwest corner above an elevation of 3,800 feet. This area includes approximately 23 acres or approximately 11% of the subject property. Retaining the Agriculture/EFU designation in this area would not impact the applicant's ability to extract sand and gravel from the 2s stratum identified in the geotechnical report as the primary aggregate resource on the site. In addition, while the relationship between the quantity of a particular aggregate resource and its spatial distribution on the subject property is not explicitly stated in the geotechnical report, basalt resources will still be available for extraction at lower elevations and in other portions of the property. Highway 20 is a designated landscape management feature in the comprehensive plan. While the Landscape Management Combining Zone extends a quarter mile from the centerline of Highway 20 and the subject property lies outside this zone, the purpose of the zone is to maintain and enhance scenic vistas and natural landscapes as seen from designated roads. The southwest portion of the subject property is visible across a valley running parallel to Highway 20. The majority of the area within the combining zone slopes downward away from the highway. However, the County program does not allow exclusion of a potential surface mine from the inventory of aggregate resources for protection of scenic views alone. PA-96-3/ZC-96-4 Page 8 Therefore, i order to protect confl ting Goal 5 resources, the significant winter deer range habitat, staff recommends the plan amendment/zone change exclude the southwest area of the property above the 3,800 foot elevation as a save zone where no mining, construction or other land disturbance shall take place. 11. The County shall identify and protect sites for the storage, extraction and processing of mineral and aggregate resources within the framework of Goal 5 and its implementing administrative rules. STAFF FINDING: The rezoning and plan designation process presently being conducted for this property by the county identifies this site for extraction, processing and storage of mineral and aggregate resources within the framework of Goal 5 and its implementing administrative rules. The goal of the Open Space chapter of the comprehensive an is: "1. To conserve open spaces and areas of historic, natural or scenic resources. 2. To maintain and improve the quality of the air, water and land resources of Deschutes County." STAFF FINDING: Highway 20 is a designated landscape management feature and a portion of the subject property is visible from the road. However, as stated above, the County program for identifying and inventorying aggregate resources in the county does not allow excluding resources for the protection of scenic values alone. The goals of the Fish and are wildlife chapter rto f this the comprehensive plan which applicable proposal are: To conserve and protect existing fish and wildlife areas, and To maintain wildlife diversity and habitats that support the wildlife diversity in the county. STAFF FINDING: The subject property is in the deer winter range and portions of the property have been identified by ODVW staff as having excellent habitat for deer and other wildlife. Specifically, the sloped portion of the subject property in the southwest corner contains high quality vegetative cover for browse, security and warmth during the winter months. ODFW staff noted during a site visit that the lower elevations and the flat portion of the property are PA-96-3/ZC-96-4 Page 9 IM C. significantly _ower in habitat quality areas. Land Use Planning Goals in the slope,., Goal 5 and Imnlementina Administrative Rules STAFF FINDING: The County's Conflict Analysis and ESEE Findings and Decision document for Site No. , Exhibit A attached, identifies Goal 5 resources existing on the subject property, determines the quality of the resources, identifies conflicting use, analyzes the conflicts between those uses and recommends a program to achieve Goal 5, as required by Goal 5 and its implementing administrative rules. Other Goals STAFF FINDING: Deschutes County addressed compliance with Statewide Land Use Goals, other than Goal 5, at the time that it adopted its surface mining inventory in 1990 (Ordinance No. 90-029). Those findings are general, but are appropriate for applying to the present rezoning/plan designation request. Rezoning Standards eschutes Countv Code, Section 18.136.030: The applicant for a quasi-judicial rezoning must establish that the public interest is best served by rezoning the property. Factors to be demonstrated are: A. That the change conforms with the Comprehensive Plan, and the change is consistent with the Plan's introductory statement and goals. STAFF FINDING: The applicant's proposal to change the designation of the property on the comprehensive plan maps from Agriculture to Surface Mining is consistent with the goal of the Surface Mining chapter of the Comprehensive plan to identify and protect mineral and aggregate resources if the analysis of conflicting uses results in a conclusion that such resource should be protected outright or protected with limitations to minimize conflicts with other uses. The proposed zone change to Surface Mining will be consistent with the proposed surface mining comprehensive plan designation, once the plan map has been amended by the Board of County Commissioners. B. That the change in classification for property is consistent with the purpose of the proposed zone classification. PA-96-3/ZC-96-4 Page 10 the subject and intent STAFF FINDING: The purpose and intent of the proposed rezoning to SM is to implement the goals and policies of the comprehensive plan. These include allowing the development and use of identified deposits of mineral and aggregate resources consistent with Statewide Planning Goal 5, protecting health and safety of the public and residents, adjoining properties and conflicting natural resources, providing for reclamation and protection of land and water resources and providing for cooperation between private parties and governmental entities in order to achieve the purposes of the zone, comprehensive plan and state and federal agencies. The proposed zone change, from EFU to SM, is consistent with the purpose and intent of the SM zone to allow development and use of identified deposits of mineral and aggregate. resources consistent with Statewide Planning Goal S. The restrictions imposed in the SM zone on mining operations, through site plan review, are designed to assure compliance with local, state and federal regulations. The health and safety of the public and residents of adjoining properties will be protected by State of Oregon air quality regulations and county site plan review. Conflicting resources are identified and balanced against the value of the mineral and aggregate resource in the attached Conflict Analysis and ESEE Findings and Decision document. Limitations on the area to be designated for mining and seasonal use of the site for resource extraction are recommended to protect conflicting resources identified in the ESEE and this staff report. C. That changing the zoning will presently serve the public health, safety and welfare considering the following factors: a. The availability and efficiency of providing necessary public services and facilities. STAFF FINDING: This site is served by a graded and paved access road (the Old Bend -Burns Highway) from Highway 20. The road is lightly used and has not been maintained recently. The applicant estimates mining activity at the site will generate up to 50-75 truck loads per, day at maximum output with normal traffic levels being around 20 loads. The County's Surface Mining zone allows the County to require road improvements or fees in lieu of improvements to public roads, as a conditions of site plan approval. If the traffic resulting from this proposal warrants off-site improvements, those improvements will be required pursuant to site plan PA-96-3/ZC-96-4 Page 11 review. The .iposition of such conditic ; of will ensure that the old state highway will be to serve the needs of this site. F.- -t approval adequate The applicant states that no other public services or utilities will be required for surface mining activity on the site with the exception of water. Water is generally needed during surface mine operation for dust control and County site plan review criteria and DEQ ambient air quality and emissions standards typically require that the mine operator control dust emissions. The applicant has proposed to obtain required water off-site and haul it to the subject property if the site plan for the mine requires water to control dust. b. The impacts on surrounding land use will be consistent with the specific goals and policies contained within the Comprehensive Plan. STAFF FINDING: Surface mining is an activity that impacts surrounding lands. DCC 18.55.020 provides that a SMIA zone shall apply to all property within one-half mile of the boundary of a surface mining zone and that the extent and location of the SMIA zone shall be designated at the time the adjacent surface mining zone is designated. The SMIA zone limits the use of adjoining property for noise or dust sensitive uses or structures, effectively requiring adjoining owners to provide setback areas for the mining operation. Farm use is exempted from the provisions of the SMIA zone. The proposed rezoning will result in an expansion of the SMIA boundary presently surrounding the state owned and privately owned surface mines adjacent to this site. The imposition of a SMIA zone on adjoining properties will not prevent their use for mining or agricultural uses or other uses allowed in the EFU zone. Adjoining land is under the management of the BLM, the state and private owners and does not show evidence of any recent use although the BLM does lease land for grazing. The SMIA zone will place limitations on the siting of dwellings, but the large size of the surrounding parcels, evidenced by County Assessor Maps of the surrounding area; and the minimum lot size of 320 acres applicable to the EFU-HR subzone, would allow owners to site homes in locations that are such a distance from the subject property as to eliminate or mitigate any conflicts. Staff finds that approval of this application for rezoning will be consistent with the Surface Mining goals of the comprehensive plan and will have minimal impact on surrounding agricultural lands and the goals of the Agricultural Lands section of the plan. PA-96-3/ZC-96-4 Page 12 U- ,1 r,- I J , D. That there has been a change in circumstances since the property was last zoned, or a mistake was made in the zoning of the property in question. STAFF FINDING: At the time the property was zoned for Exclusive Farm Use, no geotechnical information existed demonstrating that mineral and aggregate resources exist on the subject property. The applicant has obtained the services of J. Andrew Siemens of Siemens & Associates, a geotechnical engineering consultant, to determine the quantity and quality of these resources on the property. Mr. Siemens has examined the property, sampled the mineral and aggregate deposits and concluded that approximately 3.6 million cubic yards of sand and gravel select fill and more than 4.1 million cubic yards of crushable basalt, cobbles and boulders for fill and aggregate use exist on the site. This new information constitutes a change in circumstances which warrant reconsideration of the County's decision to zone the subject property EFU. OAR 660-12-060, Plan and Land Use Regulation Amendment 1. Amendments to functional plans, acknowledged comprehensive plans, and land use regulations which significantly affect a transportation facility shall assure that allowed land uses are consistent with the identified function, capacity, and level of service of the facility. This shall be accomplished by either: (a) Limiting allowed land uses to be consistent with the planned function, capacity and level of service of the transportation facility; (b) Amending the TSP to provide transportation facilities adequate to support the proposed land uses consistent with the requirements of the division; or (c) Altering land use designations, densities, or design requirements to reduce demand for automobile travel and meet travel needs through other modes. 2. A plan or land use regulation amendment significantly affects a transportation facility if it: (a) Changes the functional classification of an existing or planned transportation facility; PA-96-3/ZC-96-4 Page 13 B. ,'_136_0564 (b) Changes standards implementing a functional classification system; (c) Allows types to levels of land uses which would result in levels of travel or access which are inconsistent -vith the functional classification of a trar portation facility; or (d) Would reduce the leve- of service of the facility below the minimum acceptable level identified in the TSP. 3. Determinations under section (1) and (2) of this rule shall be coordinated with affected transportation facility and service providers and other affected local governments. STAFF FINDING: The Planning comments from the Oregon Departs (ODOT) on this proposal and comm Deschutes County Department of Pu ODOT on the impacts of mini transportation facility serving However, given the fact that the was designed to serve volumes c than will be generated by mii subject property, the plan amen should not significantly affect facility. The applicant es activities on the subject propez more than 50-75 truck trips periods, and fewer trips in g Division received no ent of Transportation :nts received from the clic Works deferred to ng activity on the the subject property. Dld Bend -Burns Highway E traffic much higher Ing activity on the iment and zone change this transportation timates that mining ty should generate no per day during peak :neral. The current volume of traffic on the old state highway is very small and stems mainly from traffic to the adjacent Hap Taylor surface mine site (recently rezoned), the existing state owned surface mine, and outdoor recreation. The level of travel or access required by the surface mine will not be inconsistent with the functional classification of 'the facility nor will it reduce the level of service of the facility below the minimum acceptable level identified in the TSP. Title 22 of the County Code, Procedures Ordinance Chapter 22 of the County Code sets forth the procedures for processing applications. This application has been processed in accordance with the requirements set forth in the County Code with respect to notice, preparation of a staff report and record keeping. PA-96-3/ZC-96-4 Page 14 F. Implementing Ordinances All zone changes and comprehensive plan amendments must be adopted by the Board of County Commissioners by ordinance. Such ordinances will be prepared by the Planning Division and Legal Counsel if the Hearings Officer recommends approval of the proposed plan amendment to the Board of County Commissioners and approves the proposed zone change. CONCLUSION AND RECOMMENDATION: Based upon the findings above, staff recommends that the Hearing's Officer recommend approval of the applicant's request to amend the Comprehensive Plan to list this site on the county's inventory of mineral and aggregate resources, designate the site for Surface Mining on the plan map, and approve the proposed zone change of the subject property from Exclusive Farm Use to Surface Mining excluding the area in the southwest corner of the property above the 3,800 foot elevation. No mining activity, construction or land disturbance shall take place in this area. BJR:slr PA-96-3/ZC-96-4 Page 15 r 'JCVIW -a _ 16 \` F 1 1 n
