FINDINGS OF FACT The City Council of the City of Port Townsend, Washington, hereby adopts the following Findings of Fact: mo Standards for vegetation clearing and planting are necessary to mitigate environmental consequences of land development, and to maintain and improve the quality of Port Townsend's urban environment; and Bo Significant additional time will be required to complete adoption of a tree ordinance with comprehensive standards for vegetation clearing and planting; and Co The remaining amount of vacant land remaining in Port Townsend may be cleared of vegetation in a manner which produces adverse aesthetic and environmental impacts not envisioned in new vegetation clearing and planting standards; and D. Implementation of interim tree clearing and planting standards is necessary to protect the health and welfare of the City's residents; and mo The standards and procedures contained in the Interim Tree Ordinance reflect the minimum desired standards, and could be used by the City in evaluation and approval of vegetation clearing activities until a comprehensive tree ordinance is adopted; and Page 1 Ord. 2 799 Fo Significant trees and forest areas are an integral part of the City's character and enhance the City's appearance and livability, as well as providing significant environmental benefits and natural resource values; and Go Removal of forest lands and significant trees may cause loss of wildlife habitat, increased soil erosion, water and air quality degradation as well as loss of aesthetic value; and Ho The City has authority under RCW 76.09.240 to set standards for certain forest practices within the City, but has not yet exercised its authority to do so; and I. Current development regulations and land use policies do not provide for the preservation of significant trees; and Jo The City Council finds that it is in the public's interest and welfare that the City of Port Townsend has effective regulations that will contribute to the preservation of significant trees; and Ko The City of Port Townsend is currently reviewing its land use policies in its Comprehensive Plan, and further reviewing and updating its development regulations, including those relating to critical areas regulations (including GMA's mandate to use best available science), storm water regulations and shoreline regulations. This review and update should be done in a manner that takes into account the need to preserve significant trees to accomplish City goals and objectives in these areas; and The City needs to further study appropriate development regulations and land use policies that will achieve the objective of preserving significant trees; and M. There have been in the recent past several actions by property owners that have resulted in the loss of significant trees and harvesting of forest lands without accompanying development; and N° Immediate action is needed to adopt interim regulations to prevent the loss of significant trees. During the effective period of the interim Ordinance, which the Council declares should not exceed six months, the Planning Commission, City Council, and staff will review the City's policies and receive public comment to determine whether development regulations must be revised or implemented to prevent the removal of significant trees or harvesting of forest lands, where this is done without accompanying approved development or conversion plans, and where, if plans were in place, it would lead to the preservation of significant trees as part of Page 2 Ord. 2799 approved development or conversion of forest lands to urban development; and Oo It is necessary this Ordinance go into effective as soon as possible, to place interim controls prior to the cutting, damaging or removing of significant trees, or harvesting of forest lands, in order to provide for replacement tree planting, and/or to allow for the incorporation of existing significant trees into future land development plans; and P. This Ordinance is necessary to protect the health and safety of citizens; and Q. RCW 36.70A.390 authorizes the City Council to adopt moratoria and interim controls during periods of land use review and study. SECTION II. ADOPTION AND APPLICABILITY The Interim Tree Ordinance is hereby adopted, and shall become binding as of the effective date of this Ordinance on all properties within the City. SECTION III. FUTURE ADOPTION OF CODIFIED TREE ORDINANCE The Building and Community Development is instructed to prepare and present a tree ordinance to the Council by May 31, 2002. SECTION IV.
