Appeal Issues and Hearings Officer Response  Noncompliance with Zoning Code Chapters (Conditional Uses) and (Conditional Use Master Plans) No specific details were given as to why the decision does not comply. The Hearings Officer decision details how all approval criteria for the Conditional Use and Conditional Use Master Plan are met.  Adjustment to tree removal regulations should be limited to species on the Nuisance Plant List. No reason was given as to why tree removal should be limited to nuisance species. Findings of the Hearings Officer concluded that removal of non- nuisance species was appropriate and necessary in order to develop water facilities on the Butte (particularly the pump station).  Noncompliance with G.2(b) for Environmental Violation review. The Hearings Officer determined that removal of non-native nuisance plants, replanting with native plants, and opening a forested area provide increased habitat for meadow wildlife, increased diversity of food (plants), and increased scenic values.

Appeal Issues and Hearings Officer Response (continued)  Noncompliance with A.1(c) for Environmental Review for Master Plan development. The Hearings Officer determined that restoration and replanting of disturbed areas will provide adequate mitigation and met this criterion (conditions I and J). In addition to and beyond the required mitigation, future reviews are included in the Plan to ensure no net loss of resource values (condition H).  Would like reinclusion of the Mitigation Bank into the Master Plan (removed by the Land Use Hearings Officer). There was not enough information on the mitigation bank to determine that it met the applicable approval criteria. As details of the mitigation bank are developed, the applicant will request an amendment to the Master Plan.  Violation of A-D because there is no mention of a water treatment plant for Phase I. The water treatment plant is not part of the Master Plan because: (1) need of the treatment plant has not been established; (2) preferred location of the treatment plant has not been chosen; and (3) any construction of the treatment plant would be beyond the ten-year lifespan of the Master Plan. A possible water treatment plant on Powell Butte was mentioned in the Master Plan for compliance with C as a “…possible future use.”

Appeal Issues and Hearings Officer Response (continued)  Noncompliance with for tree removal. The Hearings Officer determined that, because of the need for regrading of the area around the pump station and its parking area, and for maintenance-related activities for the pipeline (resulting in the environmental violation), the Adjustment to allow tree cutting beyond the limits set in the Johnson Creek Basin Plan District were justified.  The proposed maintenance yard size and location is not justified. The applicant submitted justification for the maintenance yard. The Hearings Officer determined that there was sufficient justification for a 40,000 square-foot yard and approved the Plan element. No reason was given as to how the Hearings Officer’s conclusion and decision was in error.  Oppose the use of herbicides for vegetation removal. Herbicide application per se is not prohibited within an Environmental Zone, as long as it is used only to remove targeted vegetation (in this case non- native nuisance plants), and not surrounding plants.

Conclusion The Master Plan is an update and expansion of one adopted by City Council in 1996 that never received land use approvals. The Plan is generally renovation, relocation, replacement, or expansion of existing water supply and recreation development and activities. The Plan includes a maintenance program to enhance scenic and natural resources. Implementation of the Plan will have little impact on the surrounding area after construction. Park facilities are only a moderate expansion of fairly low-impact recreation activities, so any increase in traffic, noise, and other impacts to the neighborhood should be negligible. Environmental impacts are offset by restoration and ongoing enhancement and maintenance. Because of the large scale of the Master Plan, it is not possible to have the details necessary to give full land use approvals at this time. Future land use reviews will be necessary, and are outlined in the Plan.

Recommendation Uphold the Land Use Hearings Officer’s Decision to Approve: – Conditional Use Master Plan for Powell Butte Park and surrounding area. – Environmental Review for both proposed development and vegetation removal violations. – Adjustment to A to allow removal of trees greater than six inches in diameter. – Approvals are subject to conditions generally: Updating the plan and site plan Modifying development standards Modifying approval criteria for future reviews Constructing transportation access improvements Specifying planting and restoration requirements
